+# Hermes Agent v0.13.0 (v2026.5.7)
+
+**Release Date:** May 7, 2026
+**Since v0.12.0:** 864 commits · 588 merged PRs · 829 files changed · 128,366 insertions · 282 issues closed (13 P0, 36 P1) · 295 community contributors (including co-authors)
+
+> The Tenacity Release — Hermes Agent now finishes what it starts. Kanban ships as a durable multi-agent board (heartbeat, reclaim, zombie detection, auto-block on incomplete exit, per-task retries, hallucination recovery). `/goal` keeps the agent locked on a target across turns (Ralph loop). Checkpoints v2 rewrites state persistence with real pruning. Gateway auto-resumes interrupted sessions after restart. Cron grows a `no_agent` watchdog mode. A security wave closes 8 P0s — redaction is now ON by default, Discord role-allowlists are guild-scoped, WhatsApp rejects strangers by default, and TOCTOU windows close across auth.json and MCP OAuth. Google Chat becomes the 20th platform. Providers become a pluggable surface. Seven i18n locales ship.
+
+---
+
+## ✨ Highlights
+
+- **Multi-agent Kanban — delegate to an AI team that actually finishes** — Spin up a durable board, drop tasks on it, and let multiple Hermes workers pick them up, hand off, and close them out. Heartbeats, reclaim, zombie detection, retry budgets, and a hallucination gate keep the team honest. One install, many kanbans. ([#17805](https://github.com/NousResearch/hermes-agent/pull/17805), [#19653](https://github.com/NousResearch/hermes-agent/pull/19653), [#20232](https://github.com/NousResearch/hermes-agent/pull/20232), [#20332](https://github.com/NousResearch/hermes-agent/pull/20332), [#21330](https://github.com/NousResearch/hermes-agent/pull/21330), [#21183](https://github.com/NousResearch/hermes-agent/pull/21183), [#21214](https://github.com/NousResearch/hermes-agent/pull/21214))
+
+- **`/goal` — the agent doesn't forget what you asked it to do** — Lock the agent onto a target and it stays on task across turns. The Ralph loop as a first-class primitive. ([#18262](https://github.com/NousResearch/hermes-agent/pull/18262), [#18275](https://github.com/NousResearch/hermes-agent/pull/18275), [#21287](https://github.com/NousResearch/hermes-agent/pull/21287))
+
+- **Show it a video** — new `video_analyze` tool for native video understanding on Gemini and compatible multimodal models. (@alt-glitch) ([#19301](https://github.com/NousResearch/hermes-agent/pull/19301))
+
+- **Clone a voice** — xAI Custom Voices lands as a TTS provider with voice cloning support. (@alt-glitch) ([#18776](https://github.com/NousResearch/hermes-agent/pull/18776))
+
+- **Hermes speaks your language** — static gateway + CLI messages translate to 7 locales: Chinese, Japanese, German, Spanish, French, Ukrainian, and Turkish. Docs site gains a Chinese (zh-Hans) locale. ([#20231](https://github.com/NousResearch/hermes-agent/pull/20231), [#20329](https://github.com/NousResearch/hermes-agent/pull/20329), [#20467](https://github.com/NousResearch/hermes-agent/pull/20467), [#20474](https://github.com/NousResearch/hermes-agent/pull/20474), [#20430](https://github.com/NousResearch/hermes-agent/pull/20430), [#20431](https://github.com/NousResearch/hermes-agent/pull/20431))
+
+- **Google Chat — the 20th messaging platform** — plus a generic platform-plugin hooks surface so third-party adapters drop in without touching core (IRC and Teams migrated). ([#21306](https://github.com/NousResearch/hermes-agent/pull/21306), [#21331](https://github.com/NousResearch/hermes-agent/pull/21331))
+
+- **Sessions survive restarts** — gateway bounces mid-agent, `/update` restarts, source-file reloads — conversations auto-resume when the gateway comes back. ([#21192](https://github.com/NousResearch/hermes-agent/pull/21192))
+
+- **Security wave — 8 P0 closures** — redaction ON by default, Discord role-allowlists guild-scoped (CVSS 8.1 cross-guild DM bypass closed), WhatsApp rejects strangers by default, TOCTOU windows closed across `auth.json` and MCP OAuth, browser enforces cloud-metadata SSRF floor, cron prompt-injection scans assembled skill content, `hermes debug share` redacts at upload. ([#21193](https://github.com/NousResearch/hermes-agent/pull/21193), [#21241](https://github.com/NousResearch/hermes-agent/pull/21241), [#21291](https://github.com/NousResearch/hermes-agent/pull/21291), [#21176](https://github.com/NousResearch/hermes-agent/pull/21176), [#21194](https://github.com/NousResearch/hermes-agent/pull/21194), [#21228](https://github.com/NousResearch/hermes-agent/pull/21228), [#21350](https://github.com/NousResearch/hermes-agent/pull/21350), [#19318](https://github.com/NousResearch/hermes-agent/pull/19318))
+
+- **Checkpoints v2** — state persistence rewritten. Real pruning, disk guardrails, no more orphan shadow repos. ([#20709](https://github.com/NousResearch/hermes-agent/pull/20709))
+
+- **The agent lints its own writes** — post-write delta lint on `write_file` + `patch`. Python, JSON, YAML, TOML. Syntax errors surface immediately instead of shipping downstream. ([#20191](https://github.com/NousResearch/hermes-agent/pull/20191))
+
+- **`no_agent` cron mode — script-only watchdog** — cron jobs can now skip the agent entirely and just run a script. Empty stdout is silent, non-empty gets delivered verbatim. ([#19709](https://github.com/NousResearch/hermes-agent/pull/19709))
+
+- **Platform allowlists everywhere** — `allowed_channels` / `allowed_chats` / `allowed_rooms` config across Slack, Telegram, Mattermost, Matrix, and DingTalk. ([#21251](https://github.com/NousResearch/hermes-agent/pull/21251))
+
+- **Providers are now plugins** — `ProviderProfile` ABC + `plugins/model-providers/`. Drop in third-party providers without touching core. ([#20324](https://github.com/NousResearch/hermes-agent/pull/20324))
+
+- **API server — long-term memory per session** — `X-Hermes-Session-Key` header gives memory providers a stable session identifier. ([#20199](https://github.com/NousResearch/hermes-agent/pull/20199))
+
+- **MCP levels up** — SSE transport with OAuth forwarding, stale-pipe retries, image results surface as MEDIA tags instead of getting dropped, keepalive on long-lived lifecycle waits. ([#21227](https://github.com/NousResearch/hermes-agent/pull/21227), [#21323](https://github.com/NousResearch/hermes-agent/pull/21323), [#21289](https://github.com/NousResearch/hermes-agent/pull/21289), [#21328](https://github.com/NousResearch/hermes-agent/pull/21328), [#20209](https://github.com/NousResearch/hermes-agent/pull/20209))
+
+- **Curator grows subcommands** — `hermes curator archive`, `prune`, `list-archived`. Manual `hermes curator run` is synchronous now — you see results without polling. ([#20200](https://github.com/NousResearch/hermes-agent/pull/20200), [#21236](https://github.com/NousResearch/hermes-agent/pull/21236), [#21216](https://github.com/NousResearch/hermes-agent/pull/21216))

+- **Dashboard grows up** — Plugins page (manage, enable/disable, auth status) (@austinpickett), Profiles management page (@vincez-hms-coder), sortable analytics tables, reverse-proxy support via `X-Forwarded-Prefix`, new `default-large` 18px theme. ([#18095](https://github.com/NousResearch/hermes-agent/pull/18095), [#16419](https://github.com/NousResearch/hermes-agent/pull/16419), [#18192](https://github.com/NousResearch/hermes-agent/pull/18192), [#21296](https://github.com/NousResearch/hermes-agent/pull/21296), [#20820](https://github.com/NousResearch/hermes-agent/pull/20820))

+- **SearXNG + split web tools** — SearXNG ships as a native search-only backend; web tools now let you pick different backends per capability (search vs extract vs browse). (@kshitijk4poor) ([#20823](https://github.com/NousResearch/hermes-agent/pull/20823), [#20061](https://github.com/NousResearch/hermes-agent/pull/20061), [#20841](https://github.com/NousResearch/hermes-agent/pull/20841))

+
+- **`[[as_document]]` — skill media-routing directive** — skills can force the gateway to deliver output as a document on platforms that support it. ([#21210](https://github.com/NousResearch/hermes-agent/pull/21210))
+
+- **`transform_llm_output` plugin hook** — new lifecycle hook that lets plugins reshape or filter LLM output before it hits the conversation. Useful for context-window reducers and content filters. ([#21235](https://github.com/NousResearch/hermes-agent/pull/21235))
+
+- **Nous OAuth persists across profiles** — shared token store: sign in once, every profile inherits the session. ([#19712](https://github.com/NousResearch/hermes-agent/pull/19712))
+
+- **QQBot — native approval keyboards** — feature parity with Telegram / Discord approval UX. Chunked upload, quoted attachments. ([#21342](https://github.com/NousResearch/hermes-agent/pull/21342), [#21353](https://github.com/NousResearch/hermes-agent/pull/21353))

+- `plugin.yaml` `requires_env` / `optional_env` rich-dict entries —
+  auto-populate `OPTIONAL_ENV_VARS` in `hermes_cli/config.py` so the setup

+"""QQ Bot chunked upload flow.
+
+The QQ v2 API caps inline base64 uploads (``file_data`` / ``url``) at ~10 MB.
+For files between 10 MB and ~100 MB we have to use the three-step chunked
+upload flow::
+
+    1. POST /v2/{users|groups}/{id}/upload_prepare
+       → returns upload_id, block_size, and an array of pre-signed COS part URLs.
+    2. For each part:
+         PUT the part bytes to its pre-signed COS URL,
+         then POST /v2/{users|groups}/{id}/upload_part_finish to acknowledge.
+    3. POST /v2/{users|groups}/{id}/files with {"upload_id": ...}
+       → returns the ``file_info`` token the caller uses in a RichMedia
+       message.
+
+Error-code semantics (from the QQ Bot v2 API spec):
+
+- ``40093001`` — ``upload_part_finish`` retryable. Retry until the server-provided
+  ``retry_timeout`` elapses (or a local cap).
+- ``40093002`` — daily cumulative upload quota exceeded. Not retryable; surface
+  as :class:`UploadDailyLimitExceededError` so the caller can build a
+  user-friendly reply.
+
+Exceptions:
+
+- :class:`UploadDailyLimitExceededError` — daily quota hit (non-retryable).
+- :class:`UploadFileTooLargeError` — file exceeds the platform per-file limit.
+- :class:`RuntimeError` — generic upload failure (network, part PUT, complete).
+
+Ported from WideLee's qqbot-agent-sdk v1.2.2 (``media_loader.py::ChunkedUploader``)
+so the heavy-upload path stays in-tree. Authorship preserved via Co-authored-by.

+"""QQ Bot inline keyboards + approval / update-prompt senders.
+
+QQ Bot v2 supports attaching inline keyboards to outbound messages. When a
+user clicks a button, the platform dispatches an ``INTERACTION_CREATE``
+gateway event containing the button's ``data`` payload. The bot must ACK the
+interaction promptly via ``PUT /interactions/{id}`` or the user sees an
+error indicator on the button.
+
+This module provides:
+
+- :class:`InlineKeyboard` + button dataclasses — serialized into the
+  ``keyboard`` field of the outbound message body.
+- :func:`build_approval_keyboard` — 3-button ✅ once / ⭐ always / ❌ deny
+  keyboard for tool-approval flows.
+- :func:`build_update_prompt_keyboard` — Yes/No keyboard for update confirms.
+- :func:`parse_approval_button_data` / :func:`parse_update_prompt_button_data`
+  — decode the ``button_data`` payload from ``INTERACTION_CREATE``.
+- :class:`ApprovalRequest` + :class:`ApprovalSender` — high-level helper that
+  builds an approval message with keyboard and posts it to a c2c / group chat.
+
+``button_data`` formats::
+
+    approve:<session_key>:<decision>      # decision = allow-once|allow-always|deny
+    update_prompt:<answer>                # answer = y|n
+
+Ported from WideLee's qqbot-agent-sdk v1.2.2 (``approval.py`` + ``dto.py``
+keyboard types). Authorship preserved via Co-authored-by.

+"""Kanban triage specifier — flesh out a one-liner into a real spec.
+
+Used by ``hermes kanban specify [task_id | --all]``. Takes a task that
+lives in the Triage column (a rough idea, typically only a title), calls
+the auxiliary LLM to produce:
+
+  * A tightened title (optional — only replaces if the model proposes a
+    materially different one)
+  * A concrete body: goal, proposed approach, acceptance criteria
+
+and then flips the task ``triage -> todo`` via
+``kanban_db.specify_triage_task``. The dispatcher promotes it to
+``ready`` on its next tick (or immediately if there are no open parents).
+
+Design notes
+------------
+
+* This module intentionally mirrors ``hermes_cli/goals.py`` — same aux
+  client pattern, same "empty config => skip, don't crash" tolerance.
+  Keeps the surface area tiny and the failure modes predictable.
+
+* The prompt is a short system + user pair. We ask for JSON with
+  ``{title, body}``; if parsing fails, we fall back to treating the
+  whole response as the body and leave the title untouched. No
+  retry loop — one shot, keep cost bounded.
+
+* Structured output / JSON mode is not requested explicitly so the
+  specifier works on providers that don't implement it. The parse
+  is lenient (tolerates markdown code fences around the JSON).

+description: Build fully-integrated 3-statement models (IS, BS, CF) in Excel with working capital schedules, D&A roll-forwards, debt schedule, and the plugs that make cash and retained earnings tie. Pairs with excel-author.
+version: 1.0.0
+author: Anthropic (adapted by Nous Research)
+license: Apache-2.0
+metadata:
+  hermes:
+    tags: [finance, three-statement, income-statement, balance-sheet, cash-flow, excel, openpyxl, modeling]
+    related_skills: [excel-author, pptx-author, dcf-model, lbo-model]
+---
+
+## Environment
+
+This skill assumes **headless openpyxl** — you are producing an .xlsx file on disk.
+Follow the `excel-author` skill's conventions for cell coloring, formulas, named ranges, and sensitivity tables.
+Recalculate before delivery: `python /path/to/excel-author/scripts/recalc.py ./out/model.xlsx`.
+
+# 3-Statement Financial Model Template Completion
+
+Complete and populate integrated financial model templates with proper linkages between Income Statement, Balance Sheet, and Cash Flow Statement.
+
+## ⚠️ CRITICAL PRINCIPLES — Read Before Populating Any Template
+
+**Formulas over hardcodes (non-negotiable):**
+- Every projection cell, roll-forward, linkage, and subtotal MUST be an Excel formula — never a pre-computed value
+- When using Python/openpyxl: write formula strings (`ws["D15"] = "=D14*(1+Assumptions!$B$5)"`), NOT computed results (`ws["D15"] = 12500`)
+- The ONLY cells that should contain hardcoded numbers are: (1) historical actuals, (2) assumption drivers in the Assumptions tab
+- If you find yourself computing a value in Python and writing the result to a cell — STOP. Write the formula instead.
+- Why: the model must flex when scenarios toggle or assumptions change. Hardcodes break every downstream integrity check silently.
+
+**Verify step-by-step with the user:**
+1. **After mapping the template** → show the user which tabs/sections you've identified and confirm before touching any cells
+2. **After populating historicals** → show the user the historical block and confirm values/periods match source data
+3. **After building IS projections** → run the subtotal checks, show the user the projected IS, confirm before moving to BS
+4. **After building BS** → show the user the balance check (Assets = L+E) for every period, confirm before moving to CF
+5. **After building CF** → show the user the cash tie-out (CF ending cash = BS cash), confirm before finalizing
+6. **Do NOT populate the entire model end-to-end and present it complete** — break at each statement, show the work, catch errors early
+
+## Formatting — Professional Blue/Grey Palette (Default unless template/user specifies otherwise)
+
+**Keep colors minimal.** Use only blues and greys for cell fills. Do NOT introduce greens, yellows, oranges, or multiple accent colors — a clean model uses restraint.
+
+| Element | Fill | Font |
+|---|---|---|
+| Section headers (IS / BS / CF titles) | Dark blue `#1F4E79` | White bold |
+| Column headers (FY2024A, FY2025E, etc.) | Light blue `#D9E1F2` | Black bold |
+| Input cells (historicals, assumption drivers) | Light grey `#F2F2F2` or white | Blue `#0000FF` |
+| Formula cells | White | Black |
+| Cross-tab links | White | Green `#008000` |
+| Check rows / key totals | Medium blue `#BDD7EE` | Black bold |

+**That's 3 blues + 1 grey + white.** If the template has its own color scheme, follow the template instead.
+
+Font color signals *what* a cell is (input/formula/link). Fill color signals *where* you are (header/data/check).
+
+## Model Structure
+
+### Identifying Template Tab Organization
+
+Templates vary in their tab naming conventions and organization. Before populating, review all tabs to understand the template's structure. Below are common tab names and their typical contents:
+
+| Common Tab Names | Contents to Look For |
+|------------------|----------------------|
+| IS, P&L, Income Statement | Income Statement |
+| BS, Balance Sheet | Balance Sheet |
+| CF, CFS, Cash Flow | Cash Flow Statement |
+| WC, Working Capital | Working Capital Schedule |
+| DA, D&A, Depreciation, PP&E | Depreciation & Amortization Schedule |
+| Debt, Debt Schedule | Debt Schedule |
+| NOL, Tax, DTA | Net Operating Loss Schedule |
+| Assumptions, Inputs, Drivers | Driver assumptions and inputs |
+| Checks, Audit, Validation | Error-checking dashboard |
+
+**Template Review Checklist**
+- Identify which tabs exist in the template (not all templates include every schedule)
+- Note any template-specific tabs not listed above
+- Understand tab dependencies (e.g., which schedules feed into the main statements)
+- Locate input cells vs. formula cells on each tab
+
+### Understanding Template Structure
+
+Before populating a template, familiarize yourself with its existing layout to ensure data is entered in the correct locations and formulas remain intact.
+
+**Identifying Row Structure**
+- Locate the model title at top of each tab
+- Identify section headers and their visual separation
+- Find the units row indicating $ millions, %, x, etc.
+- Note column headers distinguishing Actuals vs. Estimates periods
+- Confirm period labels (e.g., FY2024A, FY2025E)
+- Identify input cells vs. formula cells (typically distinguished by font color)
+
+**Identifying Column Structure**
+- Confirm line item labels in leftmost column
+- Verify historical years precede projection years
+- Note the visual border separating historical from projected periods
+- Check for consistent column order across all tabs
+
+**Working with Named Ranges**
+Templates often use named ranges for key inputs and outputs. Before entering data:
+- Review existing named ranges in the template (Formulas → Name Manager in Excel)
+- Common named ranges include: Revenue growth rates, cost percentages, key outputs (Net Income, EBITDA, Total Debt, Cash), scenario selector cell
+- Ensure inputs are entered in cells that feed into these named ranges
+
+### Projection Period
+- Templates typically project 5 years forward from last historical year
+- Verify historical (A) vs. projected (E) columns are clearly separated
+- Confirm columns use fiscal year notation (e.g., FY2024A, FY2025E)
+
+## Margin Analysis
+
+**Note: The following margin analysis should only be performed if prompted by the user or if the template explicitly requires it. If no prompt is given, skip this section.**
+
+Calculate and display profitability margins on the Income Statement (IS) tab to track operational efficiency and enable peer comparison.
+
+### Core Margins to Include
+
+| Margin | Formula | What It Measures |
+|--------|---------|------------------|
+| Gross Margin | Gross Profit / Revenue | Pricing power, production efficiency |
+| EBITDA Margin | EBITDA / Revenue | Core operating profitability |
+| EBIT Margin | EBIT / Revenue | Operating profitability after D&A |
+| Net Income Margin | Net Income / Revenue | Bottom-line profitability |
+
+### Income Statement Layout with Margins
+
+Display margin percentages directly below each profit line item:
+- Gross Margin % below Gross Profit
+- EBIT Margin % below EBIT
+- EBITDA Margin % below EBITDA
+- Net Income Margin % below Net Income
+
+## Credit Metrics
+
+**Note: The following Credit analysis should only be performed if prompted by the user or if the template explicitly requires it. If no prompt is given, skip this section.**
+
+Calculate and display credit/leverage metrics on the Balance Sheet (BS) tab to assess financial health, debt capacity, and covenant compliance.
+
+### Core Credit Metrics to Include
+
+| Metric | Formula | What It Measures |
+|--------|---------|------------------|
+| Total Debt / EBITDA | Total Debt / LTM EBITDA | Leverage multiple |
+| Net Debt / EBITDA | (Total Debt - Cash) / LTM EBITDA | Leverage net of cash |
+| Interest Coverage | EBITDA / Interest Expense | Ability to service debt |
+| Debt / Total Cap | Total Debt / (Total Debt + Equity) | Capital structure |
+| Debt / Equity | Total Debt / Total Equity | Financial leverage |
+| Current Ratio | Current Assets / Current Liabilities | Short-term liquidity |
+| Quick Ratio | (Current Assets - Inventory) / Current Liabilities | Immediate liquidity |
+
+### Credit Metric Hierarchy Checks
+
+Validate that Upside shows strongest credit profile:
+- Leverage: Upside < Base < Downside (lower is better)
+- Coverage: Upside > Base > Downside (higher is better)
+- Liquidity: Upside > Base > Downside (higher is better)
+
+### Covenant Compliance Tracking
+
+If debt covenants are known, add explicit compliance checks comparing actual metrics to covenant thresholds.
+
+## Scenario Analysis (Base / Upside / Downside)
+
+Use a scenario toggle (dropdown) in the Assumptions tab with CHOOSE or INDEX/MATCH formulas.
+
+| Scenario | Description |
+|----------|-------------|
+| Base Case | Management guidance or consensus estimates |
+| Upside Case | Above-guidance growth, margin expansion |
+| Downside Case | Below-trend growth, margin compression |
+
+**Key Drivers to Sensitize**: Revenue growth, Gross margin, SG&A %, DSO/DIO/DPO, CapEx %, Interest rate, Tax rate.
+
+**Scenario Audit Checks**: Toggle switches all statements, BS balances in all scenarios, Cash ties out, Hierarchy holds (Upside > Base > Downside for NI, EBITDA, FCF, margins).
+
+## SEC Filings Data Extraction
+
+If the template specifically requires pulling data from SEC filings (10-K, 10-Q), see [references/sec-filings.md](references/sec-filings.md) for detailed extraction guidance. This reference is only needed when populating templates with public company data from regulatory filings.
+
+## Completing Model Templates
+
+This section provides general guidance for completing any 3-statement financial model template while preserving existing formulas and ensuring data integrity.
+
+### Step 1: Analyze the Template Structure
+
+Before entering any data, thoroughly review the template to understand its architecture:
+
+**Identify Input vs. Formula Cells**
+- Look for visual cues (font color, cell shading) that distinguish input cells from formula cells
+- Common conventions: Blue font = inputs, Black font = formulas, Green font = links to other sheets
+- Use Excel's Trace Precedents/Dependents (Formulas → Trace Precedents) to understand cell relationships
+- Check for named ranges that may control key inputs (Formulas → Name Manager)
+
+**Map the Template's Flow**
+- Identify which tabs feed into others (e.g., Assumptions → IS → BS → CF)
+- Note any supporting schedules and their linkages to main statements
+- Document the template's specific line items and structure before populating
+
+### Step 2: Filling in Data Without Breaking Formulas
+
+**Golden Rules for Data Entry**
+
+| Rule | Description |
+|------|-------------|
+| Only edit input cells | Never overwrite cells containing formulas unless intentionally replacing the formula |
+| Preserve cell references | When copying data, use Paste Values (Ctrl+Shift+V) to avoid overwriting formulas with source formatting |
+| Match the template's units | Verify if template uses thousands, millions, or actual values before entering data |
+| Respect sign conventions | Follow the template's existing sign convention (e.g., expenses as positive or negative) |
+| Check for circular references | If the template uses iterative calculations, ensure Enable Iterative Calculation is turned on |
+
+**Safe Data Entry Process**
+1. Identify the exact cells designated for input (usually highlighted or labeled)
+2. Enter historical data first, then verify formulas are calculating correctly for those periods
+3. Enter assumption drivers that feed forecast calculations
+4. Review calculated outputs to confirm formulas are working as intended
+5. If a formula cell must be modified, document the original formula before making changes
+
+**Handling Pre-Built Formulas**
+- If formulas reference cells you haven't populated yet, expect temporary errors (#REF!, #DIV/0!) until all inputs are complete
+- When formulas produce unexpected results, trace precedents to identify missing or incorrect inputs
+- Never delete rows/columns without checking for formula dependencies across all tabs
+
+### Step 3: Validating Formulas
+
+**Formula Integrity Checks**
+
+Before relying on template outputs, validate that formulas are functioning correctly:
+
+| Check Type | Method |
+|------------|--------|
+| Trace precedents | Select a formula cell → Formulas → Trace Precedents to verify it references correct inputs |
+| Trace dependents | Verify key inputs flow to expected output cells |
+| Evaluate formula | Use Formulas → Evaluate Formula to step through complex calculations |
+| Check for hardcodes | Projection formulas should reference assumptions, not contain hardcoded values |
+| Test with known values | Input simple test values to verify formulas produce expected results |
+| Cross-tab consistency | Ensure the same formula logic applies across all projection periods |
+
+**Common Formula Issues to Watch For**
+- Mixed absolute/relative references causing incorrect results when copied across periods
+- Broken links to external files or deleted ranges (#REF! errors)
+- Division by zero in early periods before revenue ramps (#DIV/0! errors)
+- Circular reference warnings (may be intentional for interest calculations)
+- Inconsistent formulas across projection columns (use Ctrl+\ to find differences)
+
+**Validating Cross-Tab Linkages**
+- Confirm values that appear on multiple tabs are linked (not duplicated)
+- Verify schedule totals tie to corresponding line items on main statements
+- Check that period labels align across all tabs
+
+### Step 4: Quality Checks by Sheet
+
+Perform these validation checks on each sheet after populating the template:
+
+**Income Statement (IS) Quality Checks**
+- Revenue figures match source data for historical periods
+- All expense line items sum to reported totals
+- Subtotals (Gross Profit, EBIT, EBT, Net Income) calculate correctly
+- Tax calculation logic is appropriate (handles losses correctly)
+- Forecast drivers reference assumptions tab (no hardcodes)
+- Period-over-period changes are directionally reasonable
+
+**Balance Sheet (BS) Quality Checks**
+- Assets = Liabilities + Equity for every period (primary check)
+- Cash balance matches Cash Flow Statement ending cash
+- Working capital accounts tie to supporting schedules (if applicable)
+- Retained Earnings rolls forward correctly: Prior RE + Net Income - Dividends +/- Adjustments = Ending RE
+- Debt balances tie to debt schedule (if applicable)
+- All balance sheet items have appropriate signs (assets positive, most liabilities positive)
+
+**Cash Flow Statement (CF) Quality Checks**
+- Net Income at top of CFO matches Income Statement Net Income
+- Non-cash add-backs (D&A, SBC, etc.) tie to their source schedules/statements
+- Working capital changes have correct signs (increase in asset = use of cash = negative)
+- CapEx ties to PP&E schedule or fixed asset roll-forward
+- Financing activities tie to changes in debt and equity accounts on BS
+- Ending Cash matches Balance Sheet Cash
+- Beginning Cash equals prior period Ending Cash
+
+**Supporting Schedule Quality Checks**
+- Opening balances equal prior period closing balances
+- Roll-forward logic is complete (Beginning + Additions - Deductions = Ending)
+- Schedule totals tie to main statement line items
+- Assumptions used in calculations match Assumptions tab
+
+### Step 5: Cross-Statement Integrity Checks
+
+After validating individual sheets, confirm the three statements are properly integrated:
+
+| Check | Formula | Expected Result |
+|-------|---------|-----------------|
+| Balance Sheet Balance | Assets - Liabilities - Equity | = 0 |
+| Cash Tie-Out | CF Ending Cash - BS Cash | = 0 |
+| Net Income Link | IS Net Income - CF Starting Net Income | = 0 |
+| Retained Earnings | Prior RE + NI - Dividends - BS Ending RE | = 0 (adjust for SBC/other items as needed) |
+
+### Step 6: Final Review
+
+Before considering the model complete:
+- Toggle through all scenarios (if applicable) to verify checks pass in each case
+- Review all #REF!, #DIV/0!, #VALUE!, and #NAME? errors and resolve or document
+- Confirm all input cells have been populated (search for placeholder values)
+- Verify units are consistent across all tabs
+- Save a clean version before making any additional modifications
+
+## Model Validation and Audit
+
+This section consolidates all validation checks and audit procedures for completed templates.
+
+### Core Linkages (Must Always Hold)
+
+See [references/formulas.md](references/formulas.md) for all formula details.
+
+| Check | Formula | Expected Result |
+|-------|---------|-----------------|
+| Balance Sheet Balance | Assets - Liabilities - Equity | = 0 |
+| Cash Tie-Out | CF Ending Cash - BS Cash | = 0 |
+| Cash Monthly vs Annual | Closing Cash (Monthly) - Closing Cash (Annual) | = 0 |
+| Net Income Link | IS Net Income - CF Starting Net Income | = 0 |
+| Retained Earnings | Prior RE + NI + SBC - Dividends - BS Ending RE | = 0 |
+| Equity Financing | ΔCommon Stock/APIC (BS) - Equity Issuance (CFF) | = 0 |
+| Year 0 Equity | Equity Raised (Year 0) - Beginning Equity Capital (Year 1) | = 0 |
+
+### Sign Convention Reference
+
+| Statement | Item | Sign Convention |
+|-----------|------|-----------------|
+| CFO | D&A, SBC | Positive (add-back) |
+| CFO | ΔAR (increase) | Negative (use of cash) |
+| CFO | ΔAP (increase) | Positive (source of cash) |
+| CFI | CapEx | Negative |
+| CFF | Debt issuance | Positive |
+| CFF | Debt repayments | Negative |
+| CFF | Dividends | Negative |
+
+### Circular Reference Handling
+
+Interest expense creates circularity: Interest → Net Income → Cash → Debt Balance → Interest
+
+Enable iterative calculation in Excel: File → Options → Formulas → Enable iterative calculation. Set maximum iterations to 100, maximum change to 0.001. Add a circuit breaker toggle in Assumptions tab.
+
+### Check Categories
+
+**Section 1: Currency Consistency**
+- Currency identified and documented in Assumptions
+- All tabs use consistent currency symbol and scale
+- Units row matches model currency
+
+**Section 2: Balance Sheet Integrity**
+- Assets = Liabilities + Equity (for each period)
+- Formula: Assets - Liabilities - Equity (must = 0)
+
+**Section 3: Cash Flow Integrity**
+- Cash ties to BS (CF Ending Cash = BS Cash)
+- Cash Monthly vs Annual: Closing Cash (Monthly) = Closing Cash (Annual)
+- NI ties to IS (CF Net Income = IS Net Income)
+- D&A ties to schedule
+- SBC ties to IS
+- ΔAR, ΔInventory, ΔAP tie to WC schedule
+- CapEx ties to DA schedule
+
+**Section 4: Retained Earnings**
+- RE roll-forward check: Prior RE + NI + SBC - Dividends = Ending RE
+- Show component breakdown for debugging
+
+**Section 5: Working Capital**
+- AR, Inventory, AP tie to BS
+- DSO, DIO, DPO reasonability checks (flag if outside normal ranges)
+
+**Section 6: Debt Schedule**
+- Total Debt ties to BS (Current + LT Debt)
+- Interest calculation ties to IS
+
+**Section 6b: Equity Financing**
+- Equity issuance proceeds tie to BS Common Stock/APIC increase
+- Cash increase from equity = Equity account increase (must balance)
+- Equity Raise Tie-Out: ΔCommon Stock/APIC (BS) = Equity Issuance (CFF) (must = 0)
+- Year 0 Equity Tie-Out: Equity Raised (Year 0) = Beginning Equity Capital (Year 1)
+
+**Section 6c: NOL Schedule**
+- Beginning NOL (Year 1 / Formation) = 0 (new business starts with zero NOL)
+- NOL increases only when EBT < 0 (losses must be realized to generate NOL)
+- DTA ties to BS (NOL Schedule DTA = BS Deferred Tax Asset)
+- NOL utilization ≤ 80% of EBT (post-2017 federal limitation)
+- NOL balance is non-negative (cannot utilize more than available)
+- NOL generated only when EBT < 0
+- Tax expense = 0 when taxable income ≤ 0
+
+**Section 7: Scenario Hierarchy**
+- Absolute metrics: Upside > Base > Downside (NI, EBITDA, FCF)
+- Margins: Upside > Base > Downside (GM%, EBITDA%, NI%)
+- Credit metrics: Upside < Base < Downside for leverage (inverted)
+
+**Section 8: Formula Integrity**
+- COGS, S&M, G&A, R&D, SBC driven by % of Revenue (no hardcodes)
+- Consistent formulas across projection years
+- No #REF!, #DIV/0!, #VALUE! errors
+
+**Section 9: Credit Metric Thresholds**
+- Flag metrics as Green/Yellow/Red based on covenant thresholds
+- Summary of any red flags
+
+### Master Check Formula
+
+Aggregate all section statuses into a single master check:
+- If all sections pass → "✓ ALL CHECKS PASS"
+- If any section fails → "✗ ERRORS DETECTED - REVIEW BELOW"
+
+### Quick Debug Workflow
+
+When Master Status shows errors:
+1. Scroll to find red-highlighted sections
+2. Identify which check category has failures
+3. Navigate to source tab to investigate
+4. Fix the underlying issue
+5. Return to Checks tab to verify resolution
+
+
+## Data sources — MCP first, web fallback
+
+Many passages below say "use the S&P Kensho MCP / Daloopa MCP / FactSet MCP". Those are commercial financial-data MCPs from the original Cowork plugin context. In Hermes:
+
+- **If you have any structured financial-data MCP configured** (Hermes supports MCP — see `native-mcp` skill), prefer it for point-in-time comps, precedent transactions, and filings.
+- **Otherwise**, fall back to:
+  - `web_search` / `web_extract` against SEC EDGAR (`https://www.sec.gov/cgi-bin/browse-edgar`) for US filings
+  - Company IR pages for press releases, earnings decks
+  - `browser_navigate` for interactive data portals
+  - User-provided data (explicitly ask when the context doesn't have it)
+- **Never fabricate**. If a multiple, precedent, or filing number can't be sourced, flag the cell as `[UNSOURCED]` and surface it to the user.

+# Formatting Standards Reference
+
+| Element | Format |
+|---------|--------|
+| Hard-coded inputs | Blue font |
+| Formulas | Black font |
+| Links to other sheets | Green font |
+| Check cells | Red if error, green if balanced |
+| Negative values | Parentheses, not minus signs |
+| Currency | No decimals for large figures, 2 decimals for per-share |
+| Percentages | 1 decimal place |
+| Headers | Bold, bottom border |
+| Units row | Include units row below headers ($ millions, %, etc.) |
+
+## Visual Separation Guidelines
+
+- Thin vertical border between historical and projected columns
+- Thick bottom border after section totals (e.g., Total Assets)
+- Single bottom border for subtotals
+- Double bottom border for grand totals
+
+## Total and Subtotal Row Formatting
+
+All total and subtotal rows must use **bold font formatting** for their numerical values to clearly distinguish aggregated figures from individual line items.
+
+### Income Statement (P&L) Tab
+| Row | Formatting |
+|-----|------------|
+| Gross Revenue | Bold |
+| Total Cost of Revenue | Bold |
+| Gross Profit | Bold |
+| Total SG&A | Bold |
+| EBITDA | Bold |
+| EBIT | Bold |
+| EBT | Bold |
+| Net Profit After Tax | Bold |
+
+### Balance Sheet Tab
+| Row | Formatting |
+|-----|------------|
+| Total Current Assets | Bold |
+| Total Non-Current Assets | Bold |
+| Total Other Assets | Bold |
+| Total Assets | Bold |
+| Total Current Liabilities | Bold |
+| Total Non-Current Liabilities | Bold |
+| Total Equity | Bold |
+| Total Liabilities and Equity | Bold |

+
+## Balance Sheet Check Row Formatting
+
+The Balance Sheet check row (below Total Liabilities and Equity) uses conditional number formatting that displays non-zero values in red. When the balance sheet balances correctly (check = 0), the values display in black or standard formatting.
+
+| Check Value | Font Color |
+|-------------|------------|
+| = 0 (balanced) | Black (standard) |
+| ≠ 0 (error) | Red |
+
+**Implementation:** Apply custom number format `[Red][<>0]0.00;[Red][<>0](0.00);0.00` or use Excel conditional formatting with the rule "Cell Value ≠ 0" → Red font.
+
+## Margin Row Formatting
+
+| Element | Format |
+|---------|--------|
+| Margin % rows | Indent, italics, 1 decimal place |
+| Positive trend | No special formatting (or subtle green) |

+| Quick Ratio | > 1.0x | 0.75x-1.0x | < 0.75x |
+
+## Conditional Formatting for Checks Tab
+
+- Cell contains pass indicator → Green fill
+- Cell contains fail indicator → Red fill
+- Cell contains warning → Yellow fill
+- Difference cells = 0 → Light green fill
+- Difference cells ≠ 0 → Light red fill
+
+## Margin Reasonability Flags
+

+# Formula Reference
+
+**IMPORTANT:** Use the formulas outlined in this reference document unless otherwise specified by the user.
+
+---
+
+## Core Linkages
+
+```
+Balance Sheet:        Assets = Liabilities + Equity
+Net Income:           IS Net Income → CF Operations (starting point)
+Cash Flow:            ΔCash = CFO + CFI + CFF
+Cash Tie-Out:         Ending Cash (CF) = Cash (BS Asset)
+Cash Monthly/Annual:  Closing Cash (Monthly) = Closing Cash (Annual)
+Retained Earnings:    Prior RE + Net Income - Dividends = Ending RE
+Equity Raise:         ΔCommon Stock/APIC (BS) = Equity Issuance (CFF)
+Year 0 Equity:        Equity Raised (Year 0) = Beginning Equity (Year 1)
+```
+
+## Gross Profit Calculation
+
+**IMPORTANT:** Gross Profit must be calculated from Net Revenue, not Gross Revenue.
+
+```
+Net Revenue - Cost of Revenue = Gross Profit
+```
+
+| Term | Definition |
+|------|------------|
+| Gross Revenue | Total revenue before any deductions |
+| Net Revenue | Gross Revenue - Returns - Allowances - Discounts |
+| Cost of Revenue | Direct costs attributable to production of goods/services sold |
+| Gross Profit | Net Revenue - Cost of Revenue |
+
+**Note:** Always use Net Revenue (also called "Net Sales" or simply "Revenue" on most financial statements) as the starting point for profitability calculations. Gross Revenue overstates the true top-line performance.
+
+## Margin Formulas
+
+```
+Gross Margin %      = Gross Profit / Net Revenue
+EBITDA              = EBIT + D&A  (or = Gross Profit - OpEx)
+EBITDA Margin %     = EBITDA / Net Revenue
+EBIT Margin %       = EBIT / Net Revenue
+Net Income Margin % = Net Income / Net Revenue
+```
+
+## Credit Metric Formulas
+
+```
+Total Debt            = Current Portion of Debt + Long-Term Debt
+Net Debt              = Total Debt - Cash
+Total Debt / EBITDA   = Total Debt / EBITDA (from IS)
+Net Debt / EBITDA     = Net Debt / EBITDA (from IS)
+Interest Coverage     = EBITDA / Interest Expense (from IS)
+Net Int Exp % Debt    = Net Interest Expense / Long-Term Debt
+Debt / Total Cap      = Total Debt / (Total Debt + Total Equity)
+Debt / Equity         = Total Debt / Total Equity
+Current Ratio         = Total Current Assets / Total Current Liabilities
+Quick Ratio           = (Total Current Assets - Inventory) / Total Current Liabilities
+```
+
+## Forecast Formulas (% of Net Revenue Method)
+
+```
+Cost of Revenue (Forecast) = Net Revenue × Cost of Revenue % Assumption
+S&M (Forecast)             = Net Revenue × S&M % Assumption
+G&A (Forecast)             = Net Revenue × G&A % Assumption
+R&D (Forecast)             = Net Revenue × R&D % Assumption
+SBC (Forecast)             = Net Revenue × SBC % Assumption
+```
+
+## Working Capital Formulas
+
+```
+Accounts Receivable
+  Prior AR
+  + Revenue (from IS)
+  - Cash Collections (plug)
+  = Ending AR
+  DSO = (AR / Revenue) × 365
+
+Inventory
+  Prior Inventory
+  + Purchases (plug)
+  - COGS (from IS)
+  = Ending Inventory
+  DIO = (Inventory / COGS) × 365
+
+Accounts Payable
+  Prior AP
+  + Purchases (from Inventory calc)
+  - Cash Payments (plug)
+  = Ending AP
+  DPO = (AP / COGS) × 365
+
+Net Working Capital = AR + Inventory - AP
+ΔWC = Current NWC - Prior NWC
+```
+
+## D&A Schedule Formulas
+
+```
+Beginning PP&E (Gross)
++ CapEx
+= Ending PP&E (Gross)
+
+Beginning Accumulated Depreciation
++ Depreciation Expense
+= Ending Accumulated Depreciation
+
+PP&E (Net) = Gross PP&E - Accumulated Depreciation
+```
+
+## Debt Schedule Formulas
+
+```
+Beginning Debt Balance
++ New Borrowings
+- Repayments
+= Ending Debt Balance
+
+Interest Expense = Avg Debt Balance × Interest Rate
+  (Use beginning balance to avoid circularity, or iterate if circular refs enabled)
+```
+
+## Retained Earnings Formula
+
+```
+Beginning Retained Earnings
++ Net Income (from IS)
++ Stock-Based Compensation (SBC) (from IS)
+- Dividends
+= Ending Retained Earnings
+```
+
+## NOL (Net Operating Loss) Schedule Formulas
+
+```
+NOL CARRYFORWARD SCHEDULE
+
+Beginning NOL Balance (Year 1 / Formation = 0)
++ NOL Generated (if EBT < 0, then ABS(EBT), else 0)
+- NOL Utilized (limited by taxable income and utilization cap)
+= Ending NOL Balance
+
+STARTING BALANCE RULE
+
+For a new business or first modeled period:
+  Beginning NOL Balance = 0
+  NOL can only increase through realized losses (EBT < 0)

+# SEC Filings Data Extraction Reference
+
+**When to Use:** Only reference this file when a model template specifically requires pulling data from SEC filings (10-K, 10-Q). For templates that provide data directly or use other data sources, this reference is not needed.
+
+---
+
+## Extracting Data from SEC Filings (10-K / 10-Q)
+
+When populating a model template with public company data, extract financials directly from SEC filings.
+
+### Step 1: Locate the Filing
+
+1. Use SEC EDGAR: `https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=[TICKER]&type=10-K`
+2. For quarterly data, use `type=10-Q`
+
+### Step 2: Identify Filing Currency
+
+Before extracting data, identify the reporting currency:
+- Check the cover page or header for reporting currency
+- Look at statement headers (e.g., "in thousands of U.S. dollars")
+- Review Note 1 (Summary of Significant Accounting Policies)
+
+**Common Currency Indicators**
+
+| Indicator | Currency |
+|-----------|----------|
+| $, USD | US Dollar |
+| €, EUR | Euro |
+| £, GBP | British Pound |
+| ¥, JPY | Japanese Yen |
+| ¥, CNY, RMB | Chinese Yuan |
+| CHF | Swiss Franc |
+| CAD, C$ | Canadian Dollar |
+
+Set model currency to match filing; document in Assumptions tab.
+
+### Step 3: Navigate to Financial Statements
+
+Within the 10-K or 10-Q, locate:
+- **Item 8** (10-K) or **Item 1** (10-Q): Financial Statements
+- Key sections to extract:
+  - Consolidated Statements of Operations (Income Statement)
+  - Consolidated Balance Sheets
+  - Consolidated Statements of Cash Flows
+  - Notes to Financial Statements (for schedule details)
+
+### Step 4: Data Extraction Mapping
+
+**Income Statement (from Consolidated Statements of Operations)**
+
+| Filing Line Item | Model Line Item |
+|------------------|-----------------|
+| Net revenues / Net sales | Revenue |
+| Cost of goods sold | COGS |
+| Selling, general and administrative | SG&A |
+| Depreciation and amortization | D&A |
+| Interest expense, net | Interest Expense |
+| Income tax expense | Taxes |
+| Net income | Net Income |
+
+**Balance Sheet (from Consolidated Balance Sheets)**
+
+| Filing Line Item | Model Line Item |
+|------------------|-----------------|
+| Cash and cash equivalents | Cash |
+| Accounts receivable, net | AR |
+| Inventories | Inventory |
+| Property, plant and equipment, net | PP&E (Net) |
+| Total assets | Total Assets |
+| Accounts payable | AP |
+| Short-term debt / Current portion of LT debt | Current Debt |
+| Long-term debt | LT Debt |
+| Retained earnings | Retained Earnings |
+| Total stockholders' equity | Total Equity |
+
+**Cash Flow Statement (from Consolidated Statements of Cash Flows)**
+
+| Filing Line Item | Model Line Item |
+|------------------|-----------------|
+| Net income | Net Income |
+| Depreciation and amortization | D&A |
+| Changes in accounts receivable | ΔAR |
+| Changes in inventories | ΔInventory |
+| Changes in accounts payable | ΔAP |
+| Capital expenditures | CapEx |
+| Proceeds from issuance of common stock | Equity Issuance |
+| Proceeds from / Repayments of debt | Debt activity |
+| Dividends paid | Dividends |
+
+### Step 5: Extract Supporting Detail from Notes
+
+For schedules, pull from Notes to Financial Statements:
+- **Note: Debt** → Maturity schedule, interest rates, covenants
+- **Note: Property, Plant & Equipment** → Gross PP&E, accumulated depreciation, useful lives
+- **Note: Revenue** → Segment breakdowns, geographic splits
+- **Note: Leases** → Operating vs. finance lease obligations
+
+### Step 6: Historical Data Requirements
+
+Extract 3 years of historical data minimum:
+- 10-K provides 3 years of IS/CF, 2 years of BS
+- For 3rd year BS, pull from prior year's 10-K
+- Use 10-Qs to fill in quarterly granularity if needed
+
+### Data Extraction Checklist
+
+- Identify reporting currency and scale (thousands, millions)
+- 3 years historical Income Statement
+- 3 years historical Cash Flow Statement
+- 3 years historical Balance Sheet
+- Verify IS Net Income = CF starting Net Income (each year)
+- Verify BS Cash = CF Ending Cash (each year)
+- Extract debt maturity schedule from notes
+- Extract D&A detail or useful life assumptions
+- Note any non-recurring / one-time items to normalize
+
+### Handling Common Filing Variations
+
+| Variation | How to Handle |
+|-----------|---------------|
+| D&A embedded in COGS/SG&A | Pull D&A from Cash Flow Statement |
+| "Other" line items are material | Check notes for breakdown |
+| Restatements | Use restated figures, note in assumptions |
+| Fiscal year ≠ calendar year | Label with fiscal year end (e.g., FYE Jan 2025) |
+| Non-USD reporting currency | Adapt model currency to match filing |

+
+## Environment
+
+This skill assumes **headless openpyxl** — you are producing an .xlsx file on disk.
+Follow the `excel-author` skill's conventions for cell coloring, formulas, named ranges, and sensitivity tables.
+Recalculate before delivery: `python /path/to/excel-author/scripts/recalc.py ./out/model.xlsx`.
+
+# Comparable Company Analysis
+
+## ⚠️ CRITICAL: Data Source Priority (READ FIRST)
+
+**ALWAYS follow this data source hierarchy:**
+
+1. **FIRST: Check for MCP data sources** - If S&P Kensho MCP, FactSet MCP, or Daloopa MCP are available, use them exclusively for financial and trading information
+2. **DO NOT use web search** if the above MCP data sources are available
+3. **ONLY if MCPs are unavailable:** Then use Bloomberg Terminal, SEC EDGAR filings, or other institutional sources
+4. **NEVER use web search as a primary data source** - it lacks the accuracy, audit trails, and reliability required for institutional-grade analysis
+
+**Why this matters:** MCP sources provide verified, institutional-grade data with proper citations. Web search results can be outdated, inaccurate, or unreliable for financial analysis.
+
+---
+
+## Overview
+This skill teaches the agent to build institutional-grade comparable company analyses that combine operating metrics, valuation multiples, and statistical benchmarking. The output is a structured Excel/spreadsheet that enables informed investment decisions through peer comparison.
+
+**Reference Material & Contextualization:**
+
+An example comparable company analysis is provided in `examples/comps_example.xlsx`. When using this or other example files in this skill directory, use them intelligently:
+
+**DO use examples for:**
+- Understanding structural hierarchy (how sections flow)
+- Grasping the level of rigor expected (statistical depth, documentation standards)
+- Learning principles (clear headers, transparent formulas, audit trails)
+
+**DO NOT use examples for:**
+- Exact reproduction of format or metrics
+- Copying layout without considering context
+- Applying the same visual style regardless of audience
+
+**ALWAYS ask yourself first:**
+1. **"Do you have a preferred format or should I adapt the template style?"**
+2. **"Who is the audience?"** (Investment committee, board presentation, quick reference, detailed memo)
+3. **"What's the key question?"** (Valuation, growth analysis, competitive positioning, efficiency)
+4. **"What's the context?"** (M&A evaluation, investment decision, sector benchmarking, performance review)
+
+**Adapt based on specifics:**
+- **Industry context**: Big tech mega-caps need different metrics than emerging SaaS startups
+- **Sector-specific needs**: Add relevant metrics early (e.g., cloud ARR, enterprise customers, developer ecosystem for tech)
+- **Company familiarity**: Well-known companies may need less background, more focus on delta analysis
+- **Decision type**: M&A requires different emphasis than ongoing portfolio monitoring
+
+**Core principle:** Use template principles (clear structure, statistical rigor, transparent formulas) but vary execution based on context. The goal is institutional-quality analysis, not institutional-looking templates.
+
+User-provided examples and explicit preferences always take precedence over defaults.
+
+## Core Philosophy
+**"Build the right structure first, then let the data tell the story."**
+
+Start with headers that force strategic thinking about what matters, input clean data, build transparent formulas, and let statistics emerge automatically. A good comp should be immediately readable by someone who didn't build it.
+
+---
+
+## ⚠️ CRITICAL: Formulas Over Hardcodes + Step-by-Step Verification
+
+**Formulas, not hardcodes:**
+- Every derived value (margin, multiple, statistic) MUST be an Excel formula referencing input cells — never a pre-computed number pasted in
+- When using Python/openpyxl to build the sheet: write `cell.value = "=E7/C7"` (formula string), NOT `cell.value = 0.687` (computed result)
+- The only hardcoded values should be raw input data (revenue, EBITDA, share price, etc.) — and every one of those gets a cell comment with its source
+- Why: the model must update automatically when an input changes. A hardcoded margin is a silent bug waiting to happen.
+
+**Verify step-by-step with the user:**
+- After setting up the structure → show the user the header layout before filling data
+- After entering raw inputs → show the user the input block and confirm sources/periods before building formulas
+- After building operating metrics formulas → show the calculated margins and sanity-check with the user before moving to valuation
+- After building valuation multiples → show the multiples and confirm they look reasonable before adding statistics
+- Do NOT build the entire sheet end-to-end and then present it — catch errors early by confirming each section
+
+---
+
+## Section 1: Document Structure & Setup
+
+### Header Block (Rows 1-3)
+```
+Row 1: [ANALYSIS TITLE] - COMPARABLE COMPANY ANALYSIS
+Row 2: [List of Companies with Tickers] • [Company 1 (TICK1)] • [Company 2 (TICK2)] • [Company 3 (TICK3)]
+Row 3: As of [Period] | All figures in [USD Millions/Billions] except per-share amounts and ratios
+```
+
+**Why this matters:** Establishes context immediately. Anyone opening this file knows what they're looking at, when it was created, and how to interpret the numbers.
+
+### Visual Convention Standards (OPTIONAL - User preferences and uploaded templates always override)
+
+**IMPORTANT: These are suggested defaults only. Always prioritize:**
+1. User's explicit formatting preferences
+2. Formatting from any uploaded template files
+3. Company/team style guides
+4. These defaults (only if no other guidance provided)
+
+**Suggested Font & Typography:**
+- **Font family**: Times New Roman (professional, readable, industry standard)
+- **Font size**: 11pt for data cells, 12pt for headers
+- **Bold text**: Section headers, company names, statistic labels
+
+**Default Color & Shading — Professional Blue/Grey Palette (minimal is better):**
+- **Keep it restrained** — only blues and greys. Do NOT introduce greens, oranges, reds, or multiple accent colors. A clean comps sheet uses 3-4 colors total.
+- **Section headers** (e.g., "OPERATING STATISTICS & FINANCIAL METRICS"):
+  - Dark blue background (`#1F4E79` or `#17365D` navy)
+  - White bold text
+  - Full row shading across all columns
+- **Column headers** (e.g., "Company", "Revenue", "Margin"):
+  - Light blue background (`#D9E1F2` or similar pale blue)
+  - Black bold text
+  - Centered alignment
+- **Data rows**:
+  - White background for company data
+  - Black text for formulas; blue text for hardcoded inputs
+- **Statistics rows** (Maximum, 75th Percentile, etc.):
+  - Light grey background (`#F2F2F2`)
+  - Black text, left-aligned labels
+- **That's the whole palette**: dark blue + light blue + light grey + white. Nothing else unless the user's template says otherwise.
+
+**Suggested Formatting Conventions:**
+- **Decimal precision**:
+  - Percentages: 1 decimal (12.3%)
+  - Multiples: 1 decimal (13.5x)
+  - Dollar amounts: No decimals, thousands separator (69,632)
+  - Margins shown as percentages: 1 decimal (68.7%)
+- **Borders**: No borders (clean, minimal appearance)
+- **Alignment**: All metrics center-aligned for clean, uniform appearance
+- **Cell dimensions**: All column widths should be uniform/even, all row heights should be consistent (creates clean, professional grid)
+
+**Note:** If the user provides a template file or specifies different formatting, use that instead.
+
+---
+
+## Section 2: Operating Statistics & Financial Metrics
+
+### Core Columns (Start with these)
+1. **Company** - Names with consistent formatting
+2. **Revenue** - Size metric (can be LTM, quarterly, or annual depending on context)
+3. **Revenue Growth** - Year-over-year percentage change
+4. **Gross Profit** - Revenue minus cost of goods sold
+5. **Gross Margin** - GP/Revenue (fundamental profitability)
+6. **EBITDA** - Earnings before interest, tax, depreciation, amortization
+7. **EBITDA Margin** - EBITDA/Revenue (operating efficiency)
+
+### Optional Additions (Choose based on industry/purpose)
+- **Quarterly vs LTM** - Include both if seasonality matters
+- **Free Cash Flow** - For capital-intensive or SaaS businesses
+- **FCF Margin** - FCF/Revenue (cash generation efficiency)
+- **Net Income** - For mature, profitable companies
+- **Operating Income** - For businesses with varying D&A
+- **CapEx metrics** - For asset-heavy industries
+- **Rule of 40** - Specifically for SaaS (Growth % + Margin %)
+- **FCF Conversion** - For quality of earnings analysis (advanced)
+
+### Formula Examples (Using Row 7 as example)
+```excel
+// Core ratios - these are always calculated
+Gross Margin (F7): =E7/C7
+EBITDA Margin (H7): =G7/C7
+
+// Optional ratios - include if relevant
+FCF Margin: =[FCF]/[Revenue]
+Net Margin: =[Net Income]/[Revenue]
+Rule of 40: =[Growth %]+[FCF Margin %]
+```
+
+**Golden Rule:** Every ratio should be [Something] / [Revenue] or [Something] / [Something from this sheet]. Keep it simple.
+
+### Statistics Block (After company data)
+
+**CRITICAL: Add statistics formulas for all comparable metrics (ratios, margins, growth rates, multiples).**
+
+```
+[Leave one blank row for visual separation]
+- Maximum: =MAX(B7:B9)
+- 75th Percentile: =QUARTILE(B7:B9,3)
+- Median: =MEDIAN(B7:B9)
+- 25th Percentile: =QUARTILE(B7:B9,1)
+- Minimum: =MIN(B7:B9)
+```
+
+**Columns that NEED statistics (comparable metrics):**
+- Revenue Growth %, Gross Margin %, EBITDA Margin %, EPS
+- EV/Revenue, EV/EBITDA, P/E, Dividend Yield %, Beta
+
+**Columns that DON'T need statistics (size metrics):**
+- Revenue, EBITDA, Net Income (absolute size varies by company scale)
+- Market Cap, Enterprise Value (not comparable across different-sized companies)
+
+**Note:** Add one blank row between company data and statistics rows for visual separation. Do NOT add a "SECTOR STATISTICS" or "VALUATION STATISTICS" header row.
+
+**Why quartiles matter:** They show distribution, not just average. A 75th percentile multiple tells you what "premium" companies trade at.
+
+---
+
+## Section 3: Valuation Multiples & Investment Metrics
+
+### Core Valuation Columns (Start with these)
+1. **Company** - Same order as operating section
+2. **Market Cap** - Current market valuation
+3. **Enterprise Value** - Market Cap ± Net Debt/Cash
+4. **EV/Revenue** - How much market pays per dollar of sales
+5. **EV/EBITDA** - How much market pays per dollar of earnings
+6. **P/E Ratio** - Price relative to net earnings
+
+### Optional Valuation Metrics (Choose based on context)
+- **FCF Yield** - FCF/Market Cap (for cash-focused analysis)
+- **PEG Ratio** - P/E/Growth Rate (for growth companies)
+- **Price/Book** - Market value vs. book value (for asset-heavy businesses)
+- **ROE/ROA** - Return metrics (for profitability comparison)
+- **Revenue/EBITDA CAGR** - Historical growth rates (for trend analysis)
+- **Asset Turnover** - Revenue/Assets (for operational efficiency)
+- **Debt/Equity** - Leverage (for capital structure analysis)
+
+**Key Principle:** Include 3-5 core multiples that matter for your industry. Don't include every possible metric just because you can.
+
+### Formula Examples
+```excel
+// Core multiples - always include these
+EV/Revenue: =[Enterprise Value]/[LTM Revenue]
+EV/EBITDA: =[Enterprise Value]/[LTM EBITDA]
+P/E Ratio: =[Market Cap]/[Net Income]
+
+// Optional multiples - include if data available
+FCF Yield: =[LTM FCF]/[Market Cap]
+PEG Ratio: =[P/E]/[Growth Rate %]
+```
+
+### Cross-Reference Rule
+**CRITICAL:** Valuation multiples MUST reference the operating metrics section. Never input the same raw data twice. If revenue is in C7, then EV/Revenue formula should reference C7.
+
+### Statistics Block
+Same structure as operating section: Max, 75th, Median, 25th, Min for every metric. Add one blank row for visual separation between company data and statistics. Do NOT add a "VALUATION STATISTICS" header row.
+
+---
+
+## Section 4: Notes & Methodology Documentation
+
+### Required Components
+
+**Data Sources & Quality:**
+- Where did the data come from? (S&P Kensho MCP, FactSet MCP, Daloopa MCP, Bloomberg, SEC filings)
+- What period does it cover? (Q4 2024, audited figures)
+- How was it verified? (Cross-checked against 10-K/10-Q)
+- Note: Prioritize MCP data sources (S&P Kensho, FactSet, Daloopa) if available for better accuracy and traceability
+
+**Key Definitions:**
+- EBITDA calculation method (Gross Profit + D&A, or Operating Income + D&A)
+- Free Cash Flow formula (Operating CF - CapEx)
+- Special metrics explained (Rule of 40, FCF Conversion)
+- Time period definitions (LTM, CAGR calculation periods)
+
+**Valuation Methodology:**
+- How was Enterprise Value calculated? (Market Cap + Net Debt)
+- What growth rates were used? (Historical CAGR, forward estimates)
+- Any adjustments made? (One-time items excluded, normalized margins)
+
+**Analysis Framework:**
+- What's the investment thesis? (Cloud/SaaS efficiency)
+- What metrics matter most? (Cash generation, capital efficiency)
+- How should readers interpret the statistics? (Quartiles provide context)
+
+---
+
+## Section 5: Choosing the Right Metrics (Decision Framework)
+
+### Start with "What question am I answering?"
+
+**"Which company is undervalued?"**
+→ Focus on: EV/Revenue, EV/EBITDA, P/E, Market Cap
+→ Skip: Operational details, growth metrics
+
+**"Which company is most efficient?"**
+→ Focus on: Gross Margin, EBITDA Margin, FCF Margin, Asset Turnover
+→ Skip: Size metrics, absolute dollar amounts
+
+**"Which company is growing fastest?"**
+→ Focus on: Revenue Growth %, EBITDA CAGR, User/Customer Growth
+→ Skip: Margin metrics, leverage ratios
+
+**"Which is the best cash generator?"**
+→ Focus on: FCF, FCF Margin, FCF Conversion, CapEx intensity
+→ Skip: EBITDA, P/E ratios
+
+### Industry-Specific Metric Selection
+
+**Software/SaaS:**
+Must have: Revenue Growth, Gross Margin, Rule of 40
+Optional: ARR, Net Dollar Retention, CAC Payback
+Skip: Asset Turnover, Inventory metrics
+
+**Manufacturing/Industrials:**
+Must have: EBITDA Margin, Asset Turnover, CapEx/Revenue
+Optional: ROA, Inventory Turns, Backlog
+Skip: Rule of 40, SaaS metrics
+
+**Financial Services:**
+Must have: ROE, ROA, Efficiency Ratio, P/E
+Optional: Net Interest Margin, Loan Loss Reserves
+Skip: Gross Margin, EBITDA (not meaningful for banks)
+
+**Retail/E-commerce:**
+Must have: Revenue Growth, Gross Margin, Inventory Turnover
+Optional: Same-Store Sales, Customer Acquisition Cost
+Skip: Heavy R&D or CapEx metrics
+
+### The "5-10 Rule"
+
+**5 operating metrics** - Revenue, Growth, 2-3 margins/efficiency metrics
+**5 valuation metrics** - Market Cap, EV, 3 multiples
+**= 10 total columns** - Enough to tell the story, not so many you lose the thread
+
+If you have more than 15 metrics, you're probably including noise. Edit ruthlessly.
+
+---
+
+## Section 6: Best Practices & Quality Checks
+
+### Before You Start
+1. **Define the peer group** - Companies must be truly comparable (similar business model, scale, geography)
+2. **Choose the right period** - LTM smooths seasonality; quarterly shows trends
+3. **Standardize units upfront** - Millions vs. billions decision affects everything
+4. **Map data sources** - Know where each number comes from
+
+### As You Build
+1. **Input all raw data first** - Complete the blue text before writing formulas
+2. **Add cell comments to ALL hard-coded inputs** - Right-click cell → Insert Comment → Document source OR assumption
+
+   **For sourced data, cite exactly where it came from:**
+   - Example: "Bloomberg Terminal - MSFT Equity DES, accessed 2024-10-02"
+   - Example: "Q4 2024 10-K filing, page 42, line item 'Total Revenue'"
+   - Example: "FactSet consensus estimate as of 2024-10-02"
+   - **Include hyperlinks when possible**: Right-click cell → Link → paste URL to SEC filing, data source, or report
+
+   **For assumptions, explain the reasoning:**
+   - Example: "Assumed 15% EBITDA margin based on peer median, company does not disclose"
+   - Example: "Estimated Enterprise Value as Market Cap + $50M net debt (from Q3 balance sheet, Q4 not yet available)"
+   - Example: "Forward P/E based on street consensus EPS of $3.45 (average of 12 analyst estimates)"
+
+   **Why this matters**: Enables audit trails, data verification, assumption transparency, and future updates
+3. **Build formulas row by row** - Test each calculation before moving on
+4. **Use absolute references for headers** - $C$6 locks the header row
+5. **Format consistently** - Percentages as percentages, not decimals
+6. **Add conditional formatting** - Highlight outliers automatically
+
+### Sanity Checks
+- **Margin test**: Gross margin > EBITDA margin > Net margin (always true by definition)
+- **Multiple reasonableness**: 
+  - EV/Revenue: typically 0.5-20x (varies widely by industry)
+  - EV/EBITDA: typically 8-25x (fairly consistent across industries)
+  - P/E: typically 10-50x (depends on growth rate)
+- **Growth-multiple correlation**: Higher growth usually means higher multiples
+- **Size-efficiency trade-off**: Larger companies often have better margins (scale benefits)
+
+### Common Mistakes to Avoid
+❌ Mixing market cap and enterprise value in formulas
+❌ Using different time periods for numerator and denominator (LTM vs quarterly)
+❌ Hardcoding numbers into formulas instead of cell references
+❌ **Hard-coded inputs without cell comments citing the source OR explaining the assumption**
+❌ Missing hyperlinks to SEC filings or data sources when available
+❌ Including too many metrics without clear purpose
+❌ Including non-comparable companies (different business models)
+❌ Using outdated data without disclosure
+❌ Calculating averages of percentages incorrectly (should be median)

+
+## Section 6: Advanced Features
+
+### Dynamic Headers
+For columns showing calculations, use clear unit labels:
+```
+Revenue Growth (YoY) % | EBITDA Margin | FCF Margin | Rule of 40
+```
+
+### Quartile Analysis Benefits
+Instead of just mean/median, quartiles show:
+- **75th percentile** = "Premium" companies trade here
+- **Median** = Typical market valuation
+- **25th percentile** = "Discount" territory
+
+This helps answer: "Is our target company trading rich or cheap vs. peers?"
+
+### Industry-Specific Modifications
+
+**Software/SaaS:**
+- Add: ARR, Net Dollar Retention, CAC Payback Period
+- Emphasize: Rule of 40, FCF margins, gross margins >70%
+
+**Healthcare:**
+- Add: R&D/Revenue, Pipeline value, Regulatory status
+- Emphasize: EBITDA margins, growth rates, reimbursement risk
+
+**Industrials:**
+- Add: Backlog, Order book trends, Geographic mix
+- Emphasize: ROIC, asset turnover, cyclical adjustments
+
+**Consumer:**
+- Add: Same-store sales, Customer acquisition cost, Brand value
+- Emphasize: Revenue growth, gross margins, inventory turns

+## Section 7: Workflow & Practical Tips
+
+### Step-by-Step Process
+1. **Set up structure** (30 minutes)
+   - Create all headers
+   - Format cells (blue for inputs, black for formulas)
+   - Lock in units and date references
+
+2. **Gather data** (60-90 minutes)
+   - Pull from primary sources (S&P Kensho MCP, FactSet MCP, Daloopa MCP if available; otherwise Bloomberg, SEC)
+   - Input all raw numbers in blue
+   - Document sources in notes section
+
+3. **Build formulas** (30 minutes)
+   - Start with simple ratios (margins)
+   - Progress to multiples (EV/Revenue)
+   - Add cross-checks (do margins make sense?)
+
+4. **Add statistics** (15 minutes)
+   - Copy formula structure for all columns
+   - Verify ranges are correct (B7:B9, not B7:B10)
+   - Check quartile logic
+
+5. **Quality control** (30 minutes)
+   - Run sanity checks
+   - Verify formula references
+   - Check for #DIV/0! or #REF! errors
+   - Compare against known benchmarks
+
+6. **Documentation** (15 minutes)
+   - Complete notes section
+   - Add data sources
+   - Define methodologies
+   - Date-stamp the analysis
+
+### Pro Tips
+- **Save templates**: Build once, reuse forever
+- **Color-code outliers**: Conditional formatting for values >2 standard deviations
+- **Link to source files**: Hyperlink to Bloomberg screenshots or SEC filings
+- **Version control**: Save as "Comps_v1_2024-12-15" with clear dating
+- **Collaborative reviews**: Have someone else check your formulas
+
+### Excel Formatting Checklist (Optional - adapt to user preferences)

+
+**Add complexity only when needed:**
+- Include quarterly AND LTM if seasonality matters
+- Add FCF metrics if cash generation is key story
+- Include industry-specific metrics (Rule of 40 for SaaS, etc.)
+- Add more statistics rows if you have >5 companies
+
+---
+
+## Section 9: Industry-Specific Additions (Optional)
+
+Only add these if they're critical to your analysis. Most comps work fine with just core metrics.
+
+**Software/SaaS:**
+Add if relevant: ARR, Net Dollar Retention, Rule of 40
+
+**Financial Services:**
+Add if relevant: ROE, Net Interest Margin, Efficiency Ratio
+
+**E-commerce:**
+Add if relevant: GMV, Take Rate, Active Buyers
+
+**Healthcare:**
+Add if relevant: R&D/Revenue, Pipeline Value, Patent Timeline
+
+**Manufacturing:**
+Add if relevant: Asset Turnover, Inventory Turns, Backlog
+
+---
+
+## Section 10: Red Flags & Warning Signs
+
+### Data Quality Issues
+🚩 Inconsistent time periods (mixing quarterly and annual)  
+🚩 Missing data without explanation  
+🚩 Significant differences between data sources (>10% variance)
+
+### Valuation Red Flags
+🚩 Negative EBITDA companies being valued on EBITDA multiples (use revenue multiples instead)  
+🚩 P/E ratios >100x without hypergrowth story  
+🚩 Margins that don't make sense for the industry
+
+### Comparability Issues
+🚩 Different fiscal year ends (causes timing problems)  
+🚩ixing pure-play and conglomerates  
+🚩 Materially different business models labeled as "comps"
+
+**When in doubt, exclude the company.** Better to have 3 perfect comps than 6 questionable ones.

+Gross Margin = Gross Profit / Revenue
+EBITDA Margin = EBITDA / Revenue
+FCF Margin = Free Cash Flow / Revenue
+FCF Conversion = FCF / Operating Cash Flow
+ROE = Net Income / Shareholders' Equity
+ROA = Net Income / Total Assets
+Asset Turnover = Revenue / Total Assets
+Debt/Equity = Total Debt / Shareholders' Equity
+```
+
+---
+
+## Key Principles Summary
+
+1. **Structure drives insight** - Right headers force right thinking
+2. **Less is more** - 5-10 metrics that matter beat 20 that don't
+3. **Choose metrics for your question** - Valuation analysis ≠ efficiency analysis
+4. **Statistics show patterns** - Median/quartiles reveal more than average
+5. **Transparency beats complexity** - Simple formulas everyone understands
+6. **Comparability is king** - Better to exclude than force a bad comp
+7. **Document your choices** - Explain which metrics and why in notes section
+
+---
+
+## Output Checklist
+
+Before delivering a comp analysis, verify:
+- [ ] All companies are truly comparable
+- [ ] Data is from consistent time periods
+- [ ] Units are clearly labeled (millions/billions)
+- [ ] Formulas reference cells, not hardcoded values
+- [ ] **All hard-coded input cells have comments with either: (1) exact data source with citation, OR (2) clear assumption with explanation**
+- [ ] **Hyperlinks added where relevant** (SEC EDGAR filings, Bloomberg pages, research reports)
+- [ ] Statistics include at least 5 metrics (Max, 75th, Med, 25th, Min)
+- [ ] Notes section documents sources and methodology
+- [ ] Visual formatting follows conventions (blue = input, black = formula)
+- [ ] Sanity checks pass (margins logical, multiples reasonable)
+- [ ] Date stamp is current ("As of [Date]")
+- [ ] Formula auditing shows no errors (#DIV/0!, #REF!, #N/A)
+
+---
+
+## Continuous Improvement
+
+After completing a comp analysis, ask:
+1. Did the statistics reveal unexpected insights?
+2. Were there any data gaps that limited analysis?
+3. Did stakeholders ask for metrics you didn't include?
+4. How long did it take vs. how long should it take?
+5. What would make this more useful next time?
+
+The best comp analyses evolve with each iteration. Save templates, learn from feedback, and refine the structure based on what decision-makers actually use.
+
+
+## Data sources — MCP first, web fallback
+
+Many passages below say "use the S&P Kensho MCP / Daloopa MCP / FactSet MCP". Those are commercial financial-data MCPs from the original Cowork plugin context. In Hermes:
+
+- **If you have any structured financial-data MCP configured** (Hermes supports MCP — see `native-mcp` skill), prefer it for point-in-time comps, precedent transactions, and filings.
+- **Otherwise**, fall back to:
+  - `web_search` / `web_extract` against SEC EDGAR (`https://www.sec.gov/cgi-bin/browse-edgar`) for US filings
+  - Company IR pages for press releases, earnings decks
+  - `browser_navigate` for interactive data portals
+  - User-provided data (explicitly ask when the context doesn't have it)
+- **Never fabricate**. If a multiple, precedent, or filing number can't be sourced, flag the cell as `[UNSOURCED]` and surface it to the user.

+
+## Environment
+
+This skill assumes **headless openpyxl** — you are producing an .xlsx file on disk.
+Follow the `excel-author` skill's conventions for cell coloring, formulas, named ranges, and sensitivity tables.
+Recalculate before delivery: `python /path/to/excel-author/scripts/recalc.py ./out/model.xlsx`.
+
+# DCF Model Builder
+
+## Overview
+
+This skill creates institutional-quality DCF models for equity valuation following investment banking standards. Each analysis produces a detailed Excel model (with sensitivity analysis included at the bottom of the DCF sheet).
+
+## Tools
+
+- Default to using all of the information provided by the user and MCP servers available for data sourcing.
+
+## Critical Constraints - Read These First
+
+These constraints apply throughout all DCF model building. Review before starting:
+
+**Formulas Over Hardcodes (NON-NEGOTIABLE):**
+- Every projection, margin, discount factor, PV, and sensitivity cell MUST be a live Excel formula — never a value computed in Python and written as a number
+- When using openpyxl: `ws["D20"] = "=D19*(1+$B$8)"` is correct; `ws["D20"] = calculated_revenue` is WRONG
+- The only hardcoded numbers permitted are: (1) raw historical inputs, (2) assumption drivers (growth rates, WACC inputs, terminal g), (3) current market data (share price, debt balance)
+- If you catch yourself computing something in Python and writing the result — STOP. The model must flex when the user changes an assumption.
+
+**Verify Step-by-Step With the User (DO NOT build end-to-end):**
+- After data retrieval → show the user the raw inputs block (revenue, margins, shares, net debt) and confirm before projecting
+- After revenue projections → show the projected top line and growth rates, confirm before building margin build
+- After FCF build → show the full FCF schedule, confirm logic before computing WACC
+- After WACC → show the calculation and inputs, confirm before discounting
+- After terminal value + PV → show the equity bridge (EV → equity value → per share), confirm before sensitivity tables
+- Catch errors at each stage — a wrong margin assumption discovered after sensitivity tables are built means rebuilding everything downstream
+
+**Sensitivity Tables:**
+- **Use an ODD number of rows and columns** (standard: 5×5, sometimes 7×7) — this guarantees a true center cell
+- **Center cell = base case.** Build the axis values so the middle row header and middle column header exactly equal the model's actual assumptions (e.g., if base WACC = 9.0%, the middle row is 9.0%; if terminal g = 3.0%, the middle column is 3.0%). The center cell's output must therefore equal the model's actual implied share price — this is the sanity check that the table is built correctly.
+- **Highlight the center cell** with the medium-blue fill (`#BDD7EE`) + bold font so it's immediately visible which cell is the base case.
+- Populate ALL cells (typically 3 tables × 25 cells = 75) with full DCF recalculation formulas
+- Use openpyxl loops to write formulas programmatically
+- NO placeholder text, NO linear approximations, NO manual steps required
+- Each cell must recalculate full DCF for that assumption combination
+
+**Cell Comments:**
+- Add cell comments AS each hardcoded value is created
+- Format: "Source: [System/Document], [Date], [Reference], [URL if applicable]"
+- Every blue input must have a comment before moving to next section
+- Do not defer to end or write "TODO: add source"
+
+**Model Layout Planning:**
+- Define ALL section row positions BEFORE writing any formulas
+- Write ALL headers and labels first
+- Write ALL section dividers and blank rows second
+- THEN write formulas using the locked row positions
+- Test formulas immediately after creation
+
+**Formula Recalculation:**
+- Run `python recalc.py model.xlsx 30` before delivery
+- Fix ALL errors until status is "success"
+- Zero formula errors required (#REF!, #DIV/0!, #VALUE!, etc.)
+
+**Scenario Blocks:**
+- Create separate blocks for Bear/Base/Bull cases
+- Show assumptions horizontally across projection years within each block
+- Use IF formulas: `=IF($B$6=1,[Bear cell],IF($B$6=2,[Base cell],[Bull cell]))`
+- Verify formulas reference correct scenario block cells
+
+## DCF Process Workflow
+
+### Step 1: Data Retrieval and Validation
+
+Fetch data from MCP servers, user provided data, and the web.
+
+**Data Sources Priority:**
+1. **MCP Servers** (if configured) - Structured financial data from providers like Daloopa
+2. **User-Provided Data** - Historical financials from their research
+3. **Web Search/Fetch** - Current prices, beta, debt and cash when needed
+
+**Validation Checklist:**
+- Verify net debt vs net cash (critical for valuation)
+- Confirm diluted shares outstanding (check for recent buybacks/issuances)
+- Validate historical margins are consistent with business model
+- Cross-check revenue growth rates with industry benchmarks
+- Verify tax rate is reasonable (typically 21-28%)
+
+### Step 2: Historical Analysis (3-5 years)
+
+Analyze and document:
+- **Revenue growth trends**: Calculate CAGR, identify drivers
+- **Margin progression**: Track gross margin, EBIT margin, FCF margin
+- **Capital intensity**: D&A and CapEx as % of revenue
+- **Working capital efficiency**: NWC changes as % of revenue growth
+- **Return metrics**: ROIC, ROE trends
+
+Create summary tables showing:
+```
+Historical Metrics (LTM):
+Revenue: $X million
+Revenue growth: X% CAGR
+Gross margin: X%
+EBIT margin: X%
+D&A % of revenue: X%
+CapEx % of revenue: X%
+FCF margin: X%
+```
+
+### Step 3: Build Revenue Projections
+
+**Methodology:**
+1. Start with latest actual revenue (LTM or most recent fiscal year)
+2. Apply growth rates for each projection year
+3. Show both dollar amounts AND calculated growth %
+
+**Growth Rate Framework:**
+- Year 1-2: Higher growth reflecting near-term visibility
+- Year 3-4: Gradual moderation toward industry average
+- Year 5+: Approaching terminal growth rate
+
+**Formula structure:**
+- Revenue(Year N) = Revenue(Year N-1) × (1 + Growth Rate)
+- Growth %(Year N) = Revenue(Year N) / Revenue(Year N-1) - 1
+
+**Three-scenario approach:**
+```
+Bear Case: Conservative growth (e.g., 8-12%)
+Base Case: Most likely scenario (e.g., 12-16%)
+Bull Case: Optimistic growth (e.g., 16-20%)
+```
+
+### Step 4: Operating Expense Modeling
+
+**Fixed/Variable Cost Analysis:**
+
+Operating expenses should model realistic operating leverage:
+- **Sales & Marketing**: Typically 15-40% of revenue depending on business model
+- **Research & Development**: Typically 10-30% for technology companies
+- **General & Administrative**: Typically 8-15% of revenue, shows leverage as company scales
+
+**Key principles:**
+- ALL percentages based on REVENUE, not gross profit
+- Model operating leverage: % should decline as revenue scales
+- Maintain separate line items for S&M, R&D, G&A
+- Calculate EBIT = Gross Profit - Total OpEx
+
+**Margin expansion framework:**
+```
+Current State → Target State (Year 5)
+Gross Margin: X% → Y% (justify based on scale, efficiency)
+EBIT Margin: X% → Y% (result of revenue growth + opex leverage)
+```
+
+### Step 5: Free Cash Flow Calculation
+
+**Build FCF in proper sequence:**
+
+```
+EBIT
+(-) Taxes (EBIT × Tax Rate)
+= NOPAT (Net Operating Profit After Tax)
+(+) D&A (non-cash expense, % of revenue)
+(-) CapEx (% of revenue, typically 4-8%)
+(-) Δ NWC (change in working capital)
+= Unlevered Free Cash Flow
+```
+
+**Working Capital Modeling:**
+- Calculate as % of revenue change (delta revenue)
+- Typical range: -2% to +2% of revenue change
+- Negative number = source of cash (working capital release)
+- Positive number = use of cash (working capital build)
+
+**Maintenance vs Growth CapEx:**
+- Maintenance CapEx: Sustains current operations (~2-3% revenue)
+- Growth CapEx: Supports expansion (additional 2-5% revenue)
+- Total CapEx should align with company's growth strategy
+
+### Step 6: Cost of Capital (WACC) Research
+
+**CAPM Methodology for Cost of Equity:**
+
+```
+Cost of Equity = Risk-Free Rate + Beta × Equity Risk Premium
+
+Where:
+- Risk-Free Rate = Current 10-Year Treasury Yield
+- Beta = 5-year monthly stock beta vs market index
+- Equity Risk Premium = 5.0-6.0% (market standard)
+```
+
+**Cost of Debt Calculation:**
+
+```
+After-Tax Cost of Debt = Pre-Tax Cost of Debt × (1 - Tax Rate)
+
+Determine Pre-Tax Cost of Debt from:
+- Credit rating (if available)
+- Current yield on company bonds
+- Interest expense / Total Debt from financials
+```
+
+**Capital Structure Weights:**
+
+```
+Market Value Equity = Current Stock Price × Shares Outstanding
+Net Debt = Total Debt - Cash & Equivalents
+Enterprise Value = Market Cap + Net Debt
+
+Equity Weight = Market Cap / Enterprise Value
+Debt Weight = Net Debt / Enterprise Value
+
+WACC = (Cost of Equity × Equity Weight) + (After-Tax Cost of Debt × Debt Weight)
+```
+
+**Special Cases:**
+- **Net Cash Position**: If Cash > Debt, Net Debt is NEGATIVE
+  - Debt Weight may be negative
+  - WACC calculation adjusts accordingly
+- **No Debt**: WACC = Cost of Equity
+
+**Typical WACC Ranges:**
+- Large Cap, Stable: 7-9%
+- Growth Companies: 9-12%
+- High Growth/Risk: 12-15%
+
+### Step 7: Discount Rate Application (5-10 Year Forecast)
+
+**Mid-Year Convention:**
+- Cash flows assumed to occur mid-year
+- Discount Period: 0.5, 1.5, 2.5, 3.5, 4.5, etc.
+- Discount Factor = 1 / (1 + WACC)^Period
+
+**Present Value Calculation:**
+```
+For each projection year:
+PV of FCF = Unlevered FCF × Discount Factor
+
+Example (Year 1):
+FCF = $1,000
+WACC = 10%
+Period = 0.5
+Discount Factor = 1 / (1.10)^0.5 = 0.9535
+PV = $1,000 × 0.9535 = $954
+```
+
+**Projection Period Selection:**
+- **5 years**: Standard for most analyses
+- **7-10 years**: High growth companies with longer runway
+- **3 years**: Mature, stable businesses
+
+### Step 8: Terminal Value Calculation
+
+**Perpetuity Growth Method (Preferred):**
+
+```
+Terminal FCF = Final Year FCF × (1 + Terminal Growth Rate)
+Terminal Value = Terminal FCF / (WACC - Terminal Growth Rate)
+
+Critical Constraint: Terminal Growth < WACC (otherwise infinite value)
+```
+
+**Terminal Growth Rate Selection:**
+- Conservative: 2.0-2.5% (GDP growth rate)
+- Moderate: 2.5-3.5%
+- Aggressive: 3.5-5.0% (only for market leaders)
+
+**Do not exceed**: Risk-free rate or long-term GDP growth
+
+**Exit Multiple Method (Alternative):**
+```
+Terminal Value = Final Year EBITDA × Exit Multiple
+
+Where Exit Multiple comes from:
+- Industry comparable trading multiples
+- Precedent transaction multiples
+- Typical range: 8-15x EBITDA
+```
+
+**Present Value of Terminal Value:**
+```
+PV of Terminal Value = Terminal Value / (1 + WACC)^Final Period
+
+Where Final Period accounts for timing:
+5-year model with mid-year convention: Period = 4.5
+```
+
+**Terminal Value Sanity Check:**
+- Should represent 50-70% of Enterprise Value
+- If >75%, model may be over-reliant on terminal assumptions
+- If <40%, check if terminal assumptions are too conservative
+
+### Step 9: Enterprise to Equity Value Bridge
+
+**Valuation Summary Structure:**
+
+```
+(+) Sum of PV of Projected FCFs = $X million
+(+) PV of Terminal Value = $Y million
+= Enterprise Value = $Z million
+
+(-) Net Debt [or + Net Cash if negative] = $A million
+= Equity Value = $B million
+
+÷ Diluted Shares Outstanding = C million shares
+= Implied Price per Share = $XX.XX
+
+Current Stock Price = $YY.YY
+Implied Return = (Implied Price / Current Price) - 1 = XX%
+```
+
+**Critical Adjustments:**
+- **Net Debt = Total Debt - Cash & Equivalents**
+  - If positive: Subtract from EV (reduces equity value)
+  - If negative (Net Cash): Add to EV (increases equity value)
+- **Use Diluted Shares**: Includes options, RSUs, convertible securities
+- **Other adjustments** (if applicable):
+  - Minority interests
+  - Pension liabilities
+  - Operating lease obligations
+
+**Valuation Output Format:**
+```csv
+Valuation Component,Amount ($M)
+PV Explicit FCFs,X.X
+PV Terminal Value,Y.Y
+Enterprise Value,Z.Z
+(-) Net Debt,A.A
+Equity Value,B.B
+,,
+Shares Outstanding (M),C.C
+Implied Price per Share,$XX.XX
+Current Share Price,$YY.YY
+Implied Upside/(Downside),+XX%
+```
+
+### Step 10: Sensitivity Analysis
+
+Build **three sensitivity tables** at the bottom of the DCF sheet showing how valuation changes with different assumptions:
+
+1. **WACC vs Terminal Growth** - Shows enterprise value sensitivity to discount rate and perpetuity growth
+2. **Revenue Growth vs EBIT Margin** - Shows impact of top-line growth and operating leverage
+3. **Beta vs Risk-Free Rate** - Shows sensitivity to cost of equity components
+
+**Implementation**: These are simple 2D grids (NOT Excel's "Data Table" feature) with formulas in each cell. Each cell must contain a full DCF recalculation for that specific assumption combination. See Critical Constraints section for detailed requirements on populating all 75 cells programmatically using openpyxl.
+
+<correct_patterns>
+
+This section contains all the CORRECT patterns to follow when building DCF models.
+
+### Scenario Block Selection Pattern - Follow This Approach
+
+**Assumptions are organized in separate blocks for each scenario:**
+
+**CRITICAL STRUCTURE - Three rows per section header:**
+
+```csv
+BEAR CASE ASSUMPTIONS (section header, merge cells across)
+Assumption,FY1,FY2,FY3,FY4,FY5
+Revenue Growth (%),12%,10%,9%,8%,7%
+EBIT Margin (%),45%,44%,43%,42%,41%
+
+BASE CASE ASSUMPTIONS (section header, merge cells across)
+Assumption,FY1,FY2,FY3,FY4,FY5
+Revenue Growth (%),16%,14%,12%,10%,9%
+EBIT Margin (%),48%,49%,50%,51%,52%
+
+BULL CASE ASSUMPTIONS (section header, merge cells across)
+Assumption,FY1,FY2,FY3,FY4,FY5
+Revenue Growth (%),20%,18%,15%,13%,11%
+EBIT Margin (%),50%,51%,52%,53%,54%
+```
+
+**Each scenario block MUST have a column header row** showing the projection years (FY2025E, FY2026E, etc.) immediately below the section title. Without this, users cannot tell which assumption value corresponds to which year.
+
+**How to reference assumptions - Create a consolidation column:**
+1. Case selector cell (e.g., B6) contains 1=Bear, 2=Base, or 3=Bull
+2. Create a consolidation column with INDEX or OFFSET formulas to pull from the correct scenario block
+3. Projection formulas reference the consolidation column (clean cell references)
+4. Each scenario block contains full set of DCF assumptions across projection years
+
+**Recommended consolidation column pattern (using INDEX):**
+`=INDEX(B10:D10, 1, $B$6)`
+
+**NOT this - scattered IF statements throughout:**
+`=IF($B$6=1,[Bear block cell],IF($B$6=2,[Base block cell],[Bull block cell]))`
+
+The consolidation column approach centralizes logic and makes the model easier to audit.
+
+### Correct Revenue Projection Pattern
+
+**Create a consolidation column with INDEX formulas, then reference it in projections:**
+
+**Step 1 - Consolidation column for FY1 growth:**
+`=INDEX([Bear FY1 growth]:[Bull FY1 growth], 1, $B$6)`
+
+**Step 2 - Revenue projection references the consolidation column:**
+`Revenue Year 1: =D29*(1+$E$10)`
+
+Where:
+- D29 = Prior year revenue
+- $E$10 = Consolidation column cell for FY1 growth (contains INDEX formula)
+- $B$6 = Case selector (1=Bear, 2=Base, 3=Bull)
+
+**This approach is cleaner than embedding IF statements in every projection formula** and makes it much easier to audit which scenario assumptions are being used.
+
+### Correct FCF Formula Pattern
+
+**Use consolidation columns with INDEX formulas, then reference them in FCF calculations:**
+
+**Consolidation column approach:**
+```csv
+Item,Formula,Reference
+D&A,=E29*$E$21,$E$21 = consolidation column for D&A %
+CapEx,=E29*$E$22,$E$22 = consolidation column for CapEx %
+Δ NWC,=(E29-D29)*$E$23,$E$23 = consolidation column for NWC %
+Unlevered FCF,=E57+E58-E60-E62,E57=NOPAT E58=D&A E60=CapEx E62=Δ NWC
+```
+
+**Each consolidation column cell contains an INDEX formula** that pulls from the appropriate scenario block based on case selector. This keeps projection formulas clean and auditable.
+
+Before writing formulas, confirm scenario block row locations and set up consolidation columns.
+
+### Correct Cell Comment Format
+
+**Every hardcoded value needs this format:**
+
+"Source: [System/Document], [Date], [Reference], [URL if applicable]"
+
+**Examples:**
+```csv
+Item,Source Comment
+Stock price,Source: Market data script 2025-10-12 Close price
+Shares outstanding,Source: 10-K FY2024 Page 45 Note 12
+Historical revenue,Source: 10-K FY2024 Page 32 Consolidated Statements
+Beta,Source: Market data script 2025-10-12 5-year monthly beta
+Consensus estimates,Source: Management guidance Q3 2024 earnings call
+```
+
+### Correct Assumption Table Structure
+
+**CRITICAL: Each scenario block requires THREE structural elements:**
+
+1. **Section header row** (merged cells): e.g., "BEAR CASE ASSUMPTIONS"
+2. **Column header row** showing years - THIS IS REQUIRED, DO NOT SKIP
+3. **Data rows** with assumption values
+
+**Structure:**
+```csv
+BEAR CASE ASSUMPTIONS (section header - merge across columns A:G)
+Assumption,FY1,FY2,FY3,FY4,FY5
+Revenue Growth (%),X%,X%,X%,X%,X%
+EBIT Margin (%),X%,X%,X%,X%,X%
+Terminal Growth,X%,,,,
+WACC,X%,,,,
+
+BASE CASE ASSUMPTIONS (section header - merge across columns A:G)
+Assumption,FY1,FY2,FY3,FY4,FY5
+Revenue Growth (%),X%,X%,X%,X%,X%
+EBIT Margin (%),X%,X%,X%,X%,X%
+Terminal Growth,X%,,,,
+WACC,X%,,,,
+
+BULL CASE ASSUMPTIONS (section header - merge across columns A:G)
+Assumption,FY1,FY2,FY3,FY4,FY5
+Revenue Growth (%),X%,X%,X%,X%,X%
+EBIT Margin (%),X%,X%,X%,X%,X%
+Terminal Growth,X%,,,,
+WACC,X%,,,,
+```
+
+**WITHOUT the column header row showing projection years (FY2025E, FY2026E, etc.), users cannot tell which assumption value corresponds to which year. This row is MANDATORY.**
+
+**Then create a consolidation column** (typically the next column to the right) that uses INDEX formulas to pull from the selected scenario block based on the case selector. This consolidation column is what your projection formulas reference.
+
+### Correct Row Planning Process
+
+**1. Write ALL headers and labels FIRST:**
+```csv
+Row,Content
+1,[Company Name] DCF Model
+2,Ticker | Date | Year End
+4,Case Selector
+7,KEY ASSUMPTIONS
+26,Assumption headers
+27-31,Growth assumptions
+...,...
+```
+
+**2. Write ALL section dividers and blank rows**
+
+**3. THEN write formulas using the locked row positions**
+
+**4. Test formulas immediately after creation**
+
+**Think of it like construction:**
+- Good: Pour foundation, then build walls (stable structure)
+- Bad: Build walls, then pour foundation (walls collapse)
+
+**Excel version:**
+- Good: Add headers, then write formulas (formulas stable)
+- Bad: Write formulas, then add headers (formulas break)
+
+### Correct Sensitivity Table Implementation
+
+**IMPORTANT**: These are NOT Excel's "Data Table" feature. These are simple grids where you write regular formulas using openpyxl. Yes, this means ~75 formulas total (3 tables × 25 cells each), but this is straightforward and required.
+
+**Programmatic Population with Formulas:**
+
+Each sensitivity table must be fully populated with formulas that recalculate the implied share price for each combination of assumptions. **Do not use Excel's Data Table feature** (it requires manual intervention and cannot be automated via openpyxl).
+
+**Implementation approach - CONCRETE EXAMPLE:**
+
+**Table Structure — 5×5 grid (ODD dimensions, base case centered):**
+
+If the model's base WACC = 9.0% and base terminal growth = 3.0%, build the axes symmetrically around those values:
+
+```csv
+WACC vs Terminal Growth,  2.0%,  2.5%,  3.0%,  3.5%,  4.0%
+              8.0%,       [fml], [fml], [fml], [fml], [fml]
+              8.5%,       [fml], [fml], [fml], [fml], [fml]
+              9.0%,       [fml], [fml], [★  ], [fml], [fml]   ← middle row = base WACC
+              9.5%,       [fml], [fml], [fml], [fml], [fml]
+             10.0%,       [fml], [fml], [fml], [fml], [fml]
+                                   ↑
+                          middle col = base terminal g
+```
+
+**★ = the center cell.** Its formula output MUST equal the model's actual implied share price (from the valuation summary). Apply the medium-blue fill (`#BDD7EE`) and bold font to this cell so the base case is visually anchored.
+
+**Rule for axis values:** `axis_values = [base - 2*step, base - step, base, base + step, base + 2*step]` — symmetric around the base, odd count guarantees a center.
+
+**Formula Pattern - Cell B88 (WACC=8.0%, Terminal Growth=2.0%):**
+
+The formula in B88 should recalculate the implied price using:
+- WACC from row header: `$A88` (8.0%)
+- Terminal Growth from column header: `B$87` (2.0%)
+
+**Recommended approach:** Reference the main DCF calculation but substitute these values.
+
+**Example formula structure:**
+`=([SUM of PV FCFs using $A88 as discount rate] + [Terminal Value using B$87 as growth rate and $A88 as WACC] - [Net Debt]) / [Shares]`
+
+**CRITICAL - Write a formula for EVERY cell in the 5x5 grid (25 cells per table, 75 cells total).** Use openpyxl to write these formulas programmatically in a loop. Do NOT skip this step or leave placeholder text.
+
+**Python implementation pattern:**
+```python
+# Pseudocode for populating sensitivity table
+for row_idx, wacc_value in enumerate(wacc_range):
+    for col_idx, term_growth_value in enumerate(term_growth_range):
+        # Build formula that uses wacc_value and term_growth_value
+        formula = f"=<DCF recalc using {wacc_value} and {term_growth_value}>"
+        ws.cell(row=start_row+row_idx, column=start_col+col_idx).value = formula
+```
+
+**The sensitivity tables must work immediately when the model is opened, with no manual steps required from the user.**
+
+</correct_patterns>
+
+<common_mistakes>
+
+This section contains all the WRONG patterns to avoid when building DCF models.
+
+### WRONG: Simplified Sensitivity Table Approximations or Placeholder Text
+
+**Don't use linear approximations:**
+
+```
+// WRONG - Linear approximation
+B97: =B88*(1+(0.096-0.116))    // Assumes linear relationship
+
+// WRONG - Division shortcut
+B105: =B88/(1+(E48-0.07))      // Doesn't recalculate full DCF
+```
+
+**Don't leave placeholder text:**
+```
+// WRONG - Placeholder note
+"Note: Use Excel Data Table feature (Data → What-If Analysis → Data Table) to populate sensitivity tables."
+
+// WRONG - Empty cells
+[leaving cells blank because "this is complex"]
+```
+
+**Don't confuse terminology:**
+- ❌ "Sensitivity tables need Excel's Data Table feature" (NO - that's a specific Excel tool we can't use)
+- ✅ "Sensitivity tables are simple grids with formulas in each cell" (YES - this is what we build)
+
+**Why these shortcuts are wrong:**
+- Linear approximation formulas don't actually recalculate the DCF - they just apply simple math adjustments
+- The relationships are not linear, so the results will be inaccurate
+- Placeholder text requires manual user intervention
+- Model is not immediately usable when delivered
+- Not professional or client-ready
+- Empty cells = incomplete deliverable
+
+**Common rationalization to REJECT:**
+"Writing 75+ formulas feels complex, so I'll leave a note for the user to complete it manually."
+
+**Reality:** Writing 75 formulas is straightforward when you use a loop in Python with openpyxl. Each formula follows the same pattern - just substitute the row/column values. This is a required part of the deliverable.
+
+**Instead:** Populate every sensitivity cell with formulas that recalculate the full DCF for that specific combination of assumptions
+
+### WRONG: Missing Cell Comments
+
+**Don't do this:**
+- Create all hardcoded inputs without comments
+- Think "I'll add them later"
+- Write "TODO: add source"
+- Leave blue inputs without documentation
+
+**Why it's wrong:**
+- Can't verify where data came from
+- Fails xlsx skill requirements
+- Not audit-ready
+- Wastes time fixing later
+
+**Instead:** Add cell comment AS EACH hardcoded value is created
+
+### WRONG: Formula Row References Off
+
+**Symptom:**
+The FCF section references wrong assumption rows:
+`D&A:  =E29*$E$34    // Should be $E$21, but referencing wrong row`
+`CapEx: =E29*$E$41   // Should be $E$22, but row shifted`
+
+**Why this happens:**
+1. Formulas written first
+2. Then headers inserted
+3. All row references shifted
+4. Now formulas point to wrong cells → #REF! errors
+
+**Instead:** Lock row layout FIRST, then write formulas
+
+### WRONG: Single Row for Each Assumption Across Scenarios
+
+**Don't structure assumptions like this:**
+```csv
+Assumption,Bear,Base,Bull
+Revenue Growth FY1,10%,13%,16%
+Revenue Growth FY2,9%,12%,15%
+```
+This vertical layout makes it hard to see the progression across years within each scenario.
+
+**Why it's wrong:**
+- Makes it difficult to see assumptions evolving across years within each scenario
+- Harder to compare scenario assumptions across full projection period
+- Less intuitive for reviewing scenario logic
+
+**Instead:**
+- Create separate blocks for each scenario (Bear, Base, Bull)
+- Within each block, show assumptions horizontally across projection years
+- This makes each scenario's assumptions easier to review as a cohesive set
+
+### WRONG: No Borders
+
+**Don't deliver a model without borders:**
+- No section delineation
+- All cells blend together
+- Hard to read and unprofessional
+
+**Why it's wrong:**
+- Not client-ready
+- Difficult to navigate
+- Looks amateur
+
+**Instead:** Add borders around all major sections
+
+### WRONG: Wrong Font Colors or No Font Color Distinction
+
+**Don't do this:**
+- All text is black
+- Only use fill colors (no font color changes)
+- Mix up which cells are blue vs black
+
+**Why it's wrong:**
+- Can't distinguish inputs from formulas
+- Auditing becomes impossible
+- Violates xlsx skill requirements
+
+**Instead:** Blue text for ALL hardcoded inputs, black text for ALL formulas, green for sheet links
+
+### WRONG: Operating Expenses Based on Gross Profit
+
+**Don't do this:**
+`S&M: =E33*0.15    // E33 = Gross Profit (WRONG)`
+
+**Why it's wrong:**
+- Operating expenses scale with revenue, not gross profit
+- Produces unrealistic margin progression
+- Not how businesses actually operate
+
+**Instead:**
+`S&M: =E29*0.15    // E29 = Revenue (CORRECT)`
+
+### TOP 5 ERRORS SUMMARY
+
+1. **Formula row references off** → Define ALL row positions BEFORE writing formulas
+2. **Missing cell comments** → Add comments AS cells are created, not at end
+3. **Simplified sensitivity tables** → Populate all cells with full DCF recalc formulas, not approximations
+4. **Scenario block references wrong** → Ensure IF formulas pull from correct Bear/Base/Bull blocks
+5. **No borders** → Add professional section borders for client-ready appearance
+
+In addition, be aware of these errors:
+
+### WACC Calculation Errors
+- Mixing book and market values in capital structure
+- Using equity beta instead of asset/unlevered beta incorrectly
+- Wrong tax rate application to cost of debt
+- Incorrect risk-free rate (must use current 10Y Treasury)
+- Failure to adjust for net debt vs net cash position
+
+### Growth Assumption Flaws
+- Terminal growth > WACC (creates infinite value)
+- Projection growth rates inconsistent with historical performance
+- Ignoring industry growth constraints
+- Revenue growth not aligned with unit economics
+- Margin expansion without operational justification
+
+### Terminal Value Mistakes
+- Using wrong growth method (perpetuity vs exit multiple)
+- Terminal value >80% of enterprise value (suggests over-reliance)
+- Inconsistent terminal margins with steady state assumptions
+- Wrong discount period for terminal value
+
+### Cash Flow Projection Errors
+- Operating expenses based on gross profit instead of revenue
+- D&A/CapEx percentages misaligned with business model
+- Working capital changes not properly calculated
+- Tax rate inconsistency between years
+- NOPAT calculation errors
+
+**These errors are the most common. Re-read this section before starting any DCF build.**
+
+</common_mistakes>
+
+## Excel File Creation
+
+**This skill uses the `xlsx` skill for all spreadsheet operations.** The xlsx skill provides:
+- Standardized formula construction rules
+- Number formatting conventions
+- Automated formula recalculation via `recalc.py` script
+- Comprehensive error checking and validation
+
+All Excel files created by this skill must follow xlsx skill requirements, including zero formula errors and proper recalculation.
+
+## Quality Rubric
+
+Every DCF model must maximize for:
+1. **Realistic revenue and margin assumptions** based on historical performance
+2. **Appropriate cost of capital calculation** with proper CAPM methodology
+3. **Comprehensive sensitivity analysis** showing valuation ranges
+4. **Clear terminal value calculation** with supporting rationale
+5. **Professional model structure** enabling scenario analysis
+6. **Transparent documentation** of all key assumptions
+
+## Input Requirements
+
+### Minimum Required Inputs
+1. **Company identifier**: Ticker symbol or company name
+2. **Growth assumptions**: Revenue growth rates for projection period (or "use consensus")
+3. **Optional parameters**:
+   - Projection period (default: 5 years)
+   - Scenario cases (Bear/Base/Bull growth and margin assumptions)
+   - Terminal growth rate (default: 2.5-3.0%)
+   - Specific WACC inputs if not using CAPM
+
+## Excel Model Structure
+
+### Sheet Architecture
+
+Create **two sheets**:
+
+1. **DCF** - Main valuation model with sensitivity analysis at bottom
+2. **WACC** - Cost of capital calculation
+
+**CRITICAL**: Sensitivity tables go at the BOTTOM of the DCF sheet (not on a separate sheet). This keeps all valuation outputs together.
+
+### Formula Recalculation (MANDATORY)
+
+After creating or modifying the Excel model, **recalculate all formulas** using the `recalc.py` script from the `excel-author` skill:
+
+```bash
+python recalc.py [path_to_excel_file] [timeout_seconds]
+```
+
+Example:
+```bash
+python recalc.py AAPL_DCF_Model_2025-10-12.xlsx 30
+```
+
+The script will:
+- Recalculate all formulas in all sheets using LibreOffice
+- Scan ALL cells for Excel errors (#REF!, #DIV/0!, #VALUE!, #NAME?, #NULL!, #NUM!, #N/A)
+- Return detailed JSON with error locations and counts
+
+**Expected output format:**
+```json
+{
+  "status": "success",           // or "errors_found"
+  "total_errors": 0,              // Total error count
+  "total_formulas": 42,           // Number of formulas in file
+  "error_summary": {}             // Only present if errors found
+}
+```
+
+**If errors are found**, the output will include details:
+```json
+{
+  "status": "errors_found",
+  "total_errors": 2,
+  "total_formulas": 42,
+  "error_summary": {
+    "#REF!": {
+      "count": 2,
+      "locations": ["DCF!B25", "DCF!C25"]
+    }
+  }
+}
+```
+
+**Fix all errors** and re-run recalc.py until status is "success" before delivering the model.
+
+### Formatting Standards
+
+**IMPORTANT**: Follow the xlsx skill for formula construction rules and number formatting conventions. The DCF skill adds specific visual presentation standards.
+
+**Color Scheme - Two Layers**:
+
+**Layer 1: Font Colors (MANDATORY from xlsx skill)**
+- **Blue text (RGB: 0,0,255)**: ALL hardcoded inputs (stock price, shares, historical data, assumptions)
+- **Black text (RGB: 0,0,0)**: ALL formulas and calculations
+- **Green text (RGB: 0,128,0)**: Links to other sheets (WACC sheet references)
+
+**Layer 2: Fill Colors — Professional Blue/Grey Palette (Default unless user specifies otherwise)**
+- **Keep it minimal** — use only blues and greys for fills. Do NOT introduce greens, yellows, oranges, or multiple accent colors. A model with too many colors looks amateurish.
+- **Default fill palette:**
+  - **Section headers**: Dark blue (RGB: 31,78,121 / `#1F4E79`) background with white bold text
+  - **Sub-headers/column headers**: Light blue (RGB: 217,225,242 / `#D9E1F2`) background with black bold text
+  - **Input cells**: Light grey (RGB: 242,242,242 / `#F2F2F2`) background with blue font — or just white with blue font if you want maximum minimalism
+  - **Calculated cells**: White background with black font
+  - **Output/summary rows** (per-share value, EV, etc.): Medium blue (RGB: 189,215,238 / `#BDD7EE`) background with black bold font
+- **That's it — 3 blues + 1 grey + white.** Resist the urge to add more.
+- User-provided templates or explicit color preferences ALWAYS override these defaults.
+
+**How the layers work together:**
+- Input cell: Blue font + light grey fill = "Hardcoded input"
+- Formula cell: Black font + white background = "Calculated value"
+- Sheet link: Green font + white background = "Reference from another sheet"
+- Key output: Black bold font + medium blue fill = "This is the answer"
+
+**Font color tells you WHAT it is (input/formula/link). Fill color tells you WHERE you are (header/data/output).**
+
+### Border Standards (REQUIRED for Professional Appearance)
+
+**Thick borders** (1.5pt) around major sections:
+- KEY INPUTS section
+- PROJECTION ASSUMPTIONS section
+- 5-YEAR CASH FLOW PROJECTION section
+- TERMINAL VALUE section
+- VALUATION SUMMARY section
+- Each SENSITIVITY ANALYSIS table
+
+**Medium borders** (1pt) between sub-sections:
+- Company Details vs Historical Performance
+- Growth Assumptions vs EBIT Margin vs FCF Parameters
+
+**Thin borders** (0.5pt) around data tables:
+- Scenario assumption tables (Bear | Base | Bull | Selected)
+- Historical vs projected financials matrix
+
+**No borders:** Individual cells within tables (keep clean, scannable)
+
+**Borders are mandatory** - models without professional borders are not client-ready.
+
+**Number Formats** (follows xlsx skill standards):
+- **Years**: Format as text strings (e.g., "2024" not "2,024")
+- **Percentages**: `0.0%` (one decimal place)
+- **Currency**: `$#,##0` for millions; `$#,##0.00` for per-share - ALWAYS specify units in headers ("Revenue ($mm)")
+- **Zeros**: Use number formatting to make all zeros "-" (e.g., `$#,##0;($#,##0);-`)
+- **Large numbers**: `#,##0` with thousands separator
+- **Negative numbers**: `(#,##0)` in parentheses (NOT minus sign)
+
+**Cell Comments (MANDATORY for all hardcoded inputs)**:
+
+Per the xlsx skill, ALL hardcoded values must have cell comments documenting the source. Format: "Source: [System/Document], [Date], [Reference], [URL if applicable]"
+
+**CRITICAL**: Add comments AS CELLS ARE CREATED. Do not defer to the end.
+
+### DCF Sheet Detailed Structure
+
+**Section 1: Header**
+```csv
+Row,Content
+1,[Company Name] DCF Model
+2,Ticker: [XXX] | Date: [Date] | Year End: [FYE]
+3,Blank
+4,Case Selector Cell (1=Bear 2=Base 3=Bull)
+5,Case Name Display (formula: =IF([Selector]=1"Bear"IF([Selector]=2"Base""Bull")))
+```
+
+**Section 2: Market Data (NOT case dependent)**
+```csv
+Item,Value
+Current Stock Price,$XX.XX
+Shares Outstanding (M),XX.X
+Market Cap ($M),[Formula]
+Net Debt ($M),XXX [or Net Cash if negative]
+```
+
+**Section 3: DCF Scenario Assumptions**
+
+Create separate assumption blocks for each scenario (Bear, Base, Bull) with DCF-specific assumptions (Revenue Growth %, EBIT Margin %, Tax Rate %, D&A % of Revenue, CapEx % of Revenue, NWC Change % of ΔRev, Terminal Growth Rate, WACC) laid out horizontally across projection years. Each block must include section header, column header row showing the projection years (FY1, FY2, etc.), and data rows. See `<correct_patterns>` section "Correct Assumption Table Structure" for the exact layout.
+
+**Section 4: Historical & Projected Financials**
+
+**Reference a consolidation column (e.g., "Selected Case") that pulls from scenario blocks**, not scattered IF formulas in every projection row.
+
+```csv
+Income Statement ($M),2020A,2021A,2022A,2023A,2024E,2025E,2026E
+Revenue,XXX,XXX,XXX,XXX,[=E29*(1+$E$10)],[=F29*(1+$E$11)],[=G29*(1+$E$12)]
+  % growth,XX%,XX%,XX%,XX%,[=E29/D29-1],[=F29/E29-1],[=G29/F29-1]

+
+**Key Formula Pattern**:
+- Revenue growth: `=E29*(1+$E$10)` where $E$10 is consolidation column for Year 1 growth
+- NOT: `=E29*(1+IF($B$6=1,$B$10,IF($B$6=2,$C$10,$D$10)))`
+
+This approach is cleaner, easier to audit, and prevents formula errors by centralizing the scenario logic.
+
+**Section 5: Free Cash Flow Build**
+
+**CRITICAL**: Verify row references point to the CORRECT assumption rows. Test formulas immediately after creation.

+```
+
+**Row reference examples** (based on layout planning):
+- $E$21 = D&A % assumption (consolidation column, row 21)
+- $E$22 = CapEx % assumption (consolidation column, row 22)
+- $E$23 = NWC % assumption (consolidation column, row 23)
+- E29 = Revenue for year (row 29)
+- E45 = NOPAT for year (row 45)
+
+**Before writing formulas**: Confirm these row numbers match the actual layout. Test one column, then copy across.

+```
+
+### Sensitivity Analysis (Bottom of DCF Sheet)
+
+**TERMINOLOGY REMINDER**: "Sensitivity tables" = simple 2D grids with row headers, column headers, and formulas in each data cell. NOT Excel's "Data Table" feature (Data → What-If Analysis → Data Table). You will use openpyxl to write regular Excel formulas into each cell.
+
+**Location**: Rows 87+ on DCF sheet (NOT a separate sheet)
+
+**Three sensitivity tables, vertically stacked:**
+
+1. **WACC vs Terminal Growth** (rows 87-100) - 5x5 grid = 25 cells with formulas
+2. **Revenue Growth vs EBIT Margin** (rows 102-115) - 5x5 grid = 25 cells with formulas
+3. **Beta vs Risk-Free Rate** (rows 117-130) - 5x5 grid = 25 cells with formulas
+
+**Total formulas to write: 75** (this is required, not optional)
+
+**CRITICAL**: All sensitivity table cells must be populated programmatically with formulas using openpyxl. DO NOT use linear approximation shortcuts. DO NOT leave placeholder text or notes about manual steps. DO NOT rationalize leaving cells empty because "it's complex" - use a Python loop to generate the formulas.
+
+**Table Setup:**
+1. Create table structure with row/column headers (the assumption values to test)
+2. Populate EVERY data cell with a formula that:
+   - Uses the row header value (e.g., WACC = 9.0%)
+   - Uses the column header value (e.g., Terminal Growth = 3.0%)
+   - Recalculates the full DCF with those specific assumptions
+   - Returns the implied share price for that scenario
+3. All cells must contain working formulas when delivered
+4. Format cells with conditional formatting: Green scale for higher values, red scale for lower values
+5. Bold the base case cell
+6. Leave 1-2 blank rows between tables
+
+**No manual intervention required** - the sensitivity tables must be fully functional when the user opens the file.
+
+## Case Selector Implementation
+
+**Three-Case Framework:**
+
+### Bear Case
+- Conservative revenue growth (low end of historical range)
+- Margin compression or no expansion
+- Higher WACC (risk premium increase)
+- Lower terminal growth rate
+- Higher CapEx assumptions
+
+### Base Case
+- Consensus or management guidance revenue growth
+- Moderate margin expansion based on operating leverage
+- Current market-implied WACC
+- GDP-aligned terminal growth (2.5-3.0%)
+- Standard CapEx assumptions
+
+### Bull Case
+- Optimistic revenue growth (high end of projections)
+- Significant margin expansion
+- Lower WACC (reduced risk premium)
+- Higher terminal growth (3.5-5.0%)
+- Reduced CapEx intensity
+
+**Formula Implementation:**
+
+**DO NOT use nested IF formulas scattered throughout.** Instead, create a consolidation column that uses INDEX or OFFSET formulas to pull from the appropriate scenario block.
+
+**Recommended pattern (using INDEX):**
+`=INDEX(B10:D10, 1, $B$6)` where `B10:D10` = Bear/Base/Bull values, `1` = row offset, `$B$6` = case selector cell (1, 2, or 3)
+
+**Then reference the consolidation column** in all projections:
+`Revenue Year 1: =D29*(1+$E$10)` where $E$10 is the consolidation column value for Year 1 growth.
+
+This approach centralizes scenario logic, making the model easier to audit and maintain.
+
+## Deliverables Structure
+
+**File naming**: `[Ticker]_DCF_Model_[Date].xlsx`
+
+**Two sheets**:
+1. **DCF** - Complete model with Bear/Base/Bull cases + three sensitivity tables at bottom (WACC vs Terminal Growth, Revenue Growth vs EBIT Margin, Beta vs Risk-Free Rate)
+2. **WACC** - Cost of capital calculation
+
+**Key features**: Case selector (1/2/3), consolidation column with INDEX/OFFSET formulas, color-coded cells, cell comments on all inputs, professional borders
+
+## Best Practices
+
+### Model Construction
+1. **Build incrementally**: Complete each section before moving to next
+2. **Test as building**: Enter sample numbers to verify formulas
+3. **Use consistent structure**: Similar calculations follow similar patterns
+4. **Comment complex formulas**: Add notes for unusual calculations
+5. **Build in checks**: Sum checks and balance checks where applicable
+
+### Documentation
+1. **Document all assumptions**: Explain reasoning behind key inputs
+2. **Cite data sources**: Note where each data point came from
+3. **Explain methodology**: Describe any non-standard approaches
+4. **Flag uncertainties**: Highlight areas with limited visibility
+
+### Quality Control
+1. **Cross-check calculations**: Verify math in multiple ways
+2. **Stress test assumptions**: Run sensitivity to ensure model is robust
+3. **Peer review**: Have someone else check formulas
+4. **Version control**: Save versions as work progresses
+
+## Common Variations
+
+### High-Growth Technology Companies
+- Longer projection period (7-10 years)
+- Higher initial growth rates (20-30%)
+- Significant margin expansion over time
+- Higher WACC (12-15%)
+- Model unit economics (users, ARPU, etc.)
+
+### Mature/Stable Companies
+- Shorter projection period (3-5 years)
+- Modest growth rates (GDP +1-3%)
+- Stable margins
+- Lower WACC (7-9%)
+- Focus on cash generation and capital allocation
+
+### Cyclical Companies
+- Model through economic cycle
+- Normalize margins at mid-cycle
+- Consider trough and peak scenarios
+- Adjust beta for cyclicality
+
+### Multi-Segment Companies
+- Separate DCFs for each business unit
+- Different growth rates and margins by segment
+- Sum-of-parts valuation
+- Consider synergies
+
+## Troubleshooting
+
+**If you encounter errors or unreasonable results, read [TROUBLESHOOTING.md](./TROUBLESHOOTING.md) for detailed debugging guidance.**
+
+## Workflow Integration
+
+### At Start of DCF Build
+
+1. **Gather market data**:
+   - Check for available MCP servers for current market data
+   - Use web search/fetch for stock prices, beta, and other market metrics
+   - Request from user if specific data is needed
+
+2. **Gather historical financials**:
+   - Check for available MCP servers (Daloopa, etc.)
+   - Request from user if not available via MCP
+   - Manual extraction from 10-Ks if necessary
+
+3. **Begin model construction** using the DCF methodology detailed in this skill
+
+### During Model Construction
+
+1. **Build Excel model** using openpyxl with formulas (not hardcoded values)
+2. **Follow xlsx skill conventions** for formula construction and formatting
+3. **Apply fill colors only if requested** by user or if specific brand guidelines are provided
+
+### Before Delivering Model (MANDATORY)
+
+1. **Verify structure**:
+   - Scenario blocks for Bear/Base/Bull with assumptions across projection years
+   - Case selector functional with formulas referencing correct scenario blocks
+   - Sensitivity tables at bottom of DCF sheet (not separate sheet)
+   - Font colors: Blue inputs, black formulas, green sheet links
+   - Cell comments on ALL hardcoded inputs
+   - Professional borders around major sections
+
+2. **Recalculate formulas**: Run `python recalc.py model.xlsx 30`
+
+3. **Check output**:
+   - If `status` is `"success"` → Continue to step 4
+   - If `status` is `"errors_found"` → Check `error_summary` and read [TROUBLESHOOTING.md](./TROUBLESHOOTING.md) for debugging guidance
+
+4. **Fix errors and re-run recalc.py** until status is "success"
+
+5. **Spot-check formulas**:
+   - Test one FCF formula - does it reference the correct assumption rows?
+   - Change case selector - does the consolidation column update properly?
+   - Verify revenue formulas reference consolidation column (not nested IF formulas)
+
+6. **Deliver model**
+
+### Available Data Sources
+
+- **MCP servers**: If configured (Daloopa for historical financials)
+- **Web search/fetch**: For current stock prices, beta, and market data
+- **User-provided data**: Historical financials, consensus estimates
+- **Manual extraction**: SEC EDGAR filings as fallback
+
+## Final Output Checklist
+
+Before delivering DCF model:
+
+**Required:**
+- Run `python recalc.py model.xlsx 30` until status is "success" (zero formula errors)
+- Two sheets: DCF (with sensitivity at bottom), WACC
+- Font colors: Blue=inputs, Black=formulas, Green=sheet links
+- Cell comments on ALL hardcoded inputs
+- Sensitivity tables fully populated with formulas
+- Professional borders around major sections
+
+**Validation:**
+- OpEx based on revenue (not gross profit)
+- Terminal value 50-70% of EV
+- Terminal growth < WACC
+- Tax rate 21-28%
+- File naming: `[Ticker]_DCF_Model_[Date].xlsx`
+
+## Data sources — MCP first, web fallback
+
+Many passages below say "use the S&P Kensho MCP / Daloopa MCP / FactSet MCP". Those are commercial financial-data MCPs from the original Cowork plugin context. In Hermes:
+
+- **If you have any structured financial-data MCP configured** (Hermes supports MCP — see `native-mcp` skill), prefer it for point-in-time comps, precedent transactions, and filings.
+- **Otherwise**, fall back to:
+  - `web_search` / `web_extract` against SEC EDGAR (`https://www.sec.gov/cgi-bin/browse-edgar`) for US filings
+  - Company IR pages for press releases, earnings decks
+  - `browser_navigate` for interactive data portals
+  - User-provided data (explicitly ask when the context doesn't have it)
+- **Never fabricate**. If a multiple, precedent, or filing number can't be sourced, flag the cell as `[UNSOURCED]` and surface it to the user.

+# DCF Model Troubleshooting Guide
+
+**When to read this file:** If recalc.py shows errors OR valuation results seem unreasonable OR case selector not working properly.
+
+## Model Returns Error Values
+
+### #REF! Errors
+- Usually caused by formulas referencing wrong rows after headers were inserted
+- Solution: Rebuild with correct row references, or start over following layout planning
+- Prevention: Define all row positions BEFORE writing formulas
+
+### #DIV/0! Errors
+- Division by zero or empty cells
+- Solution: Add IF statements to handle zeros: `=IF([Divisor]=0,0,[Numerator]/[Divisor])`
+
+### #VALUE! Errors
+- Wrong data type in calculation (text instead of number)
+- Solution: Verify all inputs are formatted as numbers
+
+## Valuation Seems Unreasonable
+
+### Implied price far too high
+- Check terminal value isn't >80% of EV
+- Verify terminal growth < WACC
+- Review if growth assumptions are realistic
+- Consider if margins are too optimistic
+
+### Implied price far too low
+- Verify net debt vs net cash is correct
+- Check if WACC is too high
+- Review if projections are too conservative
+- Consider if terminal growth is too low
+
+## Case Selector Not Working
+
+### Consolidation column not updating when switching scenarios
+- Verify case selector cell contains 1, 2, or 3
+- Check INDEX/OFFSET formulas reference correct row range and selector cell
+- Ensure absolute references ($B$6) are used for selector
+- Test by manually changing the selector cell and verifying projection values update

+description: Build auditable Excel workbooks headless with openpyxl — blue/black/green cell conventions, formulas over hardcodes, named ranges, balance checks, sensitivity tables. Use for financial models, audit outputs, reconciliations.
+version: 1.0.0
+author: Anthropic (adapted by Nous Research)
+license: Apache-2.0
+metadata:
+  hermes:

+---
+
+# excel-author
+
+Produce an .xlsx file on disk using `openpyxl`. Follow the banker-grade conventions below so the model is auditable, flexible, and reviewable by someone other than the person who built it.
+
+Adapted from Anthropic's `xlsx-author` and `audit-xls` skills in the [anthropics/financial-services](https://github.com/anthropics/financial-services) repo. The MCP / Office-JS / Cowork-specific branches of the originals are dropped — this skill assumes headless Python.
+
+## Output contract
+
+- Write to `./out/<name>.xlsx`. Create `./out/` if it does not exist.
+- Return the relative path in your final message so downstream tools can pick it up.
+- One logical model per file. Do not append to an existing workbook unless explicitly asked.
+
+## Setup
+
+```bash
+pip install "openpyxl>=3.0"
+```
+
+## Core conventions (non-negotiable)
+
+### Blue / black / green cell color
+- **Blue** (`Font(color="0000FF")`) — hardcoded input a human entered. Revenue drivers, WACC inputs, terminal growth, market data.
+- **Black** (default) — formula. Every derived cell is a live Excel formula.
+- **Green** (`Font(color="006100")`) — link to another sheet or external file.
+
+A reviewer can then scan the sheet and immediately see what's an assumption vs. what's computed.
+
+### Formulas over hardcodes
+Every calculation cell MUST be a formula string, never a number computed in Python and pasted as a value.
+
+```python
+# WRONG — silent bug waiting to happen
+ws["D20"] = revenue_prior_year * (1 + growth)
+
+# CORRECT — flexes when the user changes the assumption
+ws["D20"] = "=D19*(1+$B$8)"
+```
+
+The only hardcoded numbers permitted:
+1. Raw historical inputs (actual revenues, reported EBITDA, etc.)
+2. Assumption drivers the user is meant to flex (growth rates, WACC inputs, terminal g)
+3. Current market data (share price, debt balance) — with a cell comment documenting source + date
+
+If you catch yourself computing a value in Python and writing the result, stop.
+
+### Named ranges for cross-sheet references
+Use named ranges for any figure referenced from another sheet, a deck, or a memo.
+
+```python
+from openpyxl.workbook.defined_name import DefinedName
+wb.defined_names["WACC"] = DefinedName("WACC", attr_text="Inputs!$C$8")
+# then elsewhere:
+calc["D30"] = "=D29/WACC"
+```
+
+### Balance checks tab
+Include a `Checks` tab that ties everything and surfaces TRUE/FALSE:
+- Balance sheet balances (assets = liabilities + equity)
+- Cash flow ties to period-over-period cash change on the BS
+- Sum-of-parts ties to consolidated totals
+- No rogue hardcodes inside calc ranges
+
+Example:
+```python
+checks = wb.create_sheet("Checks")
+checks["A2"] = "BS balances"
+checks["B2"] = "=IS!D20-IS!D21-IS!D22"
+checks["C2"] = "=ABS(B2)<0.01"  # TRUE/FALSE
+```
+
+### Cell comments on every hardcoded input
+Add the comment AS you create the cell, not later.
+
+```python
+from openpyxl.comments import Comment
+ws["C2"] = 1_250_000_000
+ws["C2"].font = Font(color="0000FF")
+ws["C2"].comment = Comment("Source: 10-K FY2024, p.47, revenue line", "analyst")
+```
+
+Format: `Source: [System/Document], [Date], [Reference], [URL if applicable]`.
+
+Never defer sourcing. Never write `TODO: add source`.
+
+## Skeleton: typical financial model
+
+```python
+from openpyxl import Workbook
+from openpyxl.styles import Font, PatternFill, Alignment, Border, Side
+from openpyxl.comments import Comment
+from openpyxl.utils import get_column_letter
+from pathlib import Path
+
+BLUE = Font(color="0000FF")
+BLACK = Font(color="000000")
+GREEN = Font(color="006100")
+BOLD = Font(bold=True)
+HEADER_FILL = PatternFill("solid", fgColor="1F4E79")
+HEADER_FONT = Font(color="FFFFFF", bold=True)
+
+wb = Workbook()
+
+# --- Inputs tab ---
+inp = wb.active
+inp.title = "Inputs"
+inp["A1"] = "MARKET DATA & KEY INPUTS"
+inp["A1"].font = HEADER_FONT
+inp["A1"].fill = HEADER_FILL
+inp.merge_cells("A1:C1")
+
+inp["B3"] = "Revenue FY2024"
+inp["C3"] = 1_250_000_000
+inp["C3"].font = BLUE
+inp["C3"].comment = Comment("Source: 10-K FY2024 p.47", "model")
+
+inp["B4"] = "Growth Rate"
+inp["C4"] = 0.12
+inp["C4"].font = BLUE
+
+# --- Calc tab ---
+calc = wb.create_sheet("DCF")
+calc["B2"] = "Projected Revenue"
+calc["C2"] = "=Inputs!C3*(1+Inputs!C4)"   # formula, black
+
+# --- Checks tab ---
+chk = wb.create_sheet("Checks")
+chk["A2"] = "BS balances"
+chk["B2"] = "=ABS(BS!D20-BS!D21-BS!D22)<0.01"
+
+Path("./out").mkdir(exist_ok=True)
+wb.save("./out/model.xlsx")
+```
+
+## Section headers with merged cells
+
+openpyxl quirk: when you merge, set the value on the top-left cell and style the full range separately.
+
+```python
+ws["A7"] = "CASH FLOW PROJECTION"
+ws["A7"].font = HEADER_FONT
+ws.merge_cells("A7:H7")
+for col in range(1, 9):  # A..H
+    ws.cell(row=7, column=col).fill = HEADER_FILL
+```
+
+## Sensitivity tables
+
+Build with loops, not hardcoded formulas per cell. Rules:
+
+- **Odd number of rows/cols** (5×5 or 7×7) — guarantees a true center cell.
+- **Center cell = base case.** The middle row/col header must equal the model's actual WACC and terminal g so the center output equals the base-case implied share price. That's the sanity check.
+- **Highlight the center cell** with medium-blue fill (`"BDD7EE"`) and bold.
+- Populate every cell with a full recalculation formula — never an approximation.
+
+```python
+# 5x5 WACC (rows) x terminal growth (cols) sensitivity
+wacc_axis = [0.08, 0.085, 0.09, 0.095, 0.10]        # center row = base 9.0%
+term_axis = [0.02, 0.025, 0.03, 0.035, 0.04]        # center col = base 3.0%
+
+start_row = 40
+ws.cell(row=start_row, column=1).value = "Implied Share Price ($)"
+ws.cell(row=start_row, column=1).font = BOLD
+
+for j, g in enumerate(term_axis):
+    ws.cell(row=start_row+1, column=2+j).value = g
+    ws.cell(row=start_row+1, column=2+j).font = BLUE
+
+for i, w in enumerate(wacc_axis):
+    r = start_row + 2 + i
+    ws.cell(row=r, column=1).value = w
+    ws.cell(row=r, column=1).font = BLUE
+    for j, g in enumerate(term_axis):
+        c = 2 + j
+        # Full DCF recalc formula (simplified for illustration).
+        # In a real model this references the full projection block.
+        ws.cell(row=r, column=c).value = (
+            f"=SUMPRODUCT(FCF_range,1/(1+{w})^year_offset) + "
+            f"FCF_terminal*(1+{g})/({w}-{g})/(1+{w})^terminal_year"
+        )
+
+# Highlight center cell (base case)
+center = ws.cell(row=start_row+2+len(wacc_axis)//2,
+                 column=2+len(term_axis)//2)
+center.fill = PatternFill("solid", fgColor="BDD7EE")
+center.font = BOLD
+```
+
+## Recalculating before delivery
+
+openpyxl writes formula strings but does not compute them. Excel recalculates on open, but downstream consumers (auto-check scripts, CI) need computed values.
+
+Run LibreOffice or a dedicated recalc step before delivery:
+
+```bash
+# LibreOffice headless recalc
+libreoffice --headless --calc --convert-to xlsx ./out/model.xlsx --outdir ./out/
+```
+
+Or use a Python recalc helper (see `scripts/recalc.py` in this skill).
+
+## Model layout planning
+
+Before writing any formula:
+1. Define ALL section row positions
+2. Write ALL headers and labels
+3. Write ALL section dividers and blank rows
+4. THEN write formulas using the locked row positions
+
+This prevents the cascading-formula-breakage pattern where inserting a header row after formulas are written shifts every downstream reference.
+
+## Verify step-by-step with the user
+
+For large models (DCFs, 3-statement, LBO), stop and show the user intermediate artifacts before continuing. Catching a wrong margin assumption before you've built downstream sensitivity tables saves an hour.
+
+Checkpoint pattern:
+- After Inputs block → show raw inputs, confirm before projecting
+- After Revenue projections → confirm top line + growth
+- After FCF build → confirm the full schedule
+- After WACC → confirm inputs
+- After valuation → confirm the equity bridge
+- THEN build sensitivity tables
+
+## When NOT to use this skill
+
+- Users in a live Excel session with an Office MCP available — drive their live workbook instead.
+- Pure tabular data export with no formulas — `csv` or `pandas.to_excel` is simpler.
+- Dashboards / charts with heavy interactivity — use a real BI tool.

+---
+
+## Environment
+
+This skill assumes **headless openpyxl** — you are producing an .xlsx file on disk.
+Follow the `excel-author` skill's conventions for cell coloring, formulas, named ranges, and sensitivity tables.
+Recalculate before delivery: `python /path/to/excel-author/scripts/recalc.py ./out/model.xlsx`.
+
+---
+
+## TEMPLATE REQUIREMENT
+
+**This skill uses templates for LBO models. Always check for an attached template file first.**
+
+Before starting any LBO model:
+1. **If a template file is attached/provided**: Use that template's structure exactly - copy it and populate with the user's data
+2. **If no template is attached**: Ask the user: *"Do you have a specific LBO template you'd like me to use? If not, I can use the standard template which includes Sources & Uses, Operating Model, Debt Schedule, and Returns Analysis."*
+3. **If using the standard template**: Copy `examples/LBO_Model.xlsx` as your starting point and populate it with the user's assumptions
+
+**IMPORTANT**: When a file like `LBO_Model.xlsx` is attached, you MUST use it as your template - do not build from scratch. Even if the template seems complex or has more features than needed, copy it and adapt it to the user's requirements. Never decide to "build from scratch" when a template is provided.
+
+---
+
+## CRITICAL INSTRUCTIONS — READ FIRST
+
+Use Python/openpyxl. Write formula strings (`ws["D20"] = "=B5*B6"`), then run the `excel-author` skill's `recalc.py` helper before delivery.
+
+### Core Principles
+* **Every calculation must be an Excel formula** - NEVER compute values in Python and hardcode results into cells. When using openpyxl, write `cell.value = "=B5*B6"` (formula string), NOT `cell.value = 1250` (computed result). The model must be dynamic and update when inputs change.
+* **Use the template structure** - Follow the organization in `examples/LBO_Model.xlsx` or the user's provided template. Do not invent your own layout.
+* **Use proper cell references** - All formulas should reference the appropriate cells. Never type numbers that should come from other cells.
+* **Maintain sign convention consistency** - Follow whatever sign convention the template uses (some use negative for outflows, some use positive). Be consistent throughout.
+* **Work section by section, verify with user at each step** - Complete one section fully, show the user what was built, run the section's verification checks, and get confirmation BEFORE moving to the next section. Do NOT build the entire model end-to-end and then present it — later sections depend on earlier ones, so catching a mistake in Sources & Uses after the returns are already built means rework everywhere.
+
+### Formula Color Conventions
+* **Blue (0000FF)**: Hardcoded inputs - typed numbers that don't reference other cells
+* **Black (000000)**: Formulas with calculations - any formula using operators or functions (`=B4*B5`, `=SUM()`, `=-MAX(0,B4)`)
+* **Purple (800080)**: Links to cells on the **same tab** - direct references with no calculation (`=B9`, `=B45`)
+* **Green (008000)**: Links to cells on **different tabs** - cross-sheet references (`=Assumptions!B5`, `='Operating Model'!C10`)
+
+### Fill Color Palette — Professional Blues & Greys (Default unless user/template specifies otherwise)
+* **Keep it minimal** — only use blues and greys for cell fills. Do NOT introduce greens, yellows, reds, or multiple accents. A professional LBO model uses restraint.
+* **Default fill palette:**
+  * **Section headers** (Sources & Uses, Operating Model, etc.): Dark blue `#1F4E79` with white bold text
+  * **Column headers** (Year 1, Year 2, etc.): Light blue `#D9E1F2` with black bold text
+  * **Input cells**: Light grey `#F2F2F2` (or just white) — the blue *font* is the signal, fill is secondary
+  * **Formula/calculated cells**: White, no fill
+  * **Key outputs** (IRR, MOIC, Exit Equity): Medium blue `#BDD7EE` with black bold text
+* **That's the whole palette.** 3 blues + 1 grey + white. If the template uses its own colors, follow the template instead.
+* Note: The blue/black/purple/green **font** colors above are for distinguishing inputs vs formulas vs links. Those are separate from the **fill** palette here — both work together.
+
+### Number Formatting Standards
+* **Currency**: `$#,##0;($#,##0);"-"` or `$#,##0.0` depending on template
+* **Percentages**: `0.0%` (one decimal)
+* **Multiples**: `0.0"x"` (one decimal)
+* **MOIC/Detailed Ratios**: `0.00"x"` (two decimals for precision)
+* **All numeric cells**: Right-aligned
+
+---
+
+### Clarify Requirements First
+
+Before filling any formulas:
+
+* **Examine the template structure** - Identify all sections, understand the timeline (which columns are which periods), note any existing formulas
+* **Ask the user if anything is unclear** - If the template structure, calculation methods, or requirements are ambiguous, ask before proceeding
+* **Confirm key assumptions** - Any key inputs, calculation preferences, or specific requirements
+* **ONLY AFTER understanding the template**, proceed to fill in formulas
+
+---
+
+## TEMPLATE ANALYSIS PHASE - DO THIS FIRST
+
+Before filling any formulas, examine the template thoroughly:
+
+1. **Map the structure** - Identify where each section lives and how they relate to each other. Note which sections feed into others.
+
+2. **Understand the timeline** - Which columns represent which periods? Is there a "Closing" or "Pro Forma" column? Where does the projection period start?
+
+3. **Identify input vs formula cells** - Templates often use color coding, borders, or shading to indicate which cells need inputs vs formulas. Respect these conventions.
+
+4. **Read existing labels carefully** - The row labels tell you exactly what calculation is expected. Don't assume - read what the template is asking for.
+
+5. **Check for existing formulas** - Some templates come partially filled. Don't overwrite working formulas unless specifically asked.
+
+6. **Note template-specific conventions** - Sign conventions, subtotal structures, how sections are organized, whether there are separate tabs for different components, etc.
+
+---
+
+## FILLING FORMULAS - GENERAL APPROACH
+
+For each cell that needs a formula, follow this hierarchy:
+
+### Step 1: Check the Template
+* Does the cell already have a formula? If yes, verify it's correct and move on.
+* Is there a comment or note indicating the expected calculation?
+* Does the row/column label make the calculation obvious?
+* Do neighboring cells show a pattern you should follow?
+
+### Step 2: Check the User's Instructions
+* Did the user specify a particular calculation method?
+* Are there stated assumptions that affect this formula?
+* Any special requirements mentioned?
+
+### Step 3: Apply Standard Practice
+* If neither template nor user specifies, use standard LBO modeling conventions
+* Document any assumptions you make
+* If genuinely uncertain, ask the user
+
+---
+
+## COMMON PROBLEM AREAS
+
+The following calculation patterns frequently cause issues across LBO models. Pay special attention when you encounter these:
+
+### Balancing Sections
+* When two sections must equal (e.g., Sources = Uses), one item is typically the "plug" (balancing figure)
+* Identify which item is the plug and calculate it as the difference
+
+### Tax Calculations
+* Tax formulas should only reference the relevant income line and tax rate
+* Should NOT reference unrelated sections (e.g., debt schedules)
+* Consider whether losses create tax shields or are simply ignored
+
+### Interest and Circular References
+* Interest calculations can create circularity if they reference balances affected by cash flows
+* Use **Beginning Balance** (not average or ending) to break circular references
+* Pattern: Interest → Cash Flow → Paydown → Ending Balance (if interest uses ending balance, this circles back)
+
+### Debt Paydown / Cash Sweeps
+* When multiple debt tranches exist, there's usually a priority order
+* Cash sweep should respect the priority waterfall
+* Balances cannot go negative - use MAX or MIN functions appropriately
+
+### Returns Calculations (IRR/MOIC)
+* Cash flows must have correct signs: Investment = negative, Proceeds = positive
+* If using XIRR, need corresponding dates
+* If using IRR, cash flows should be in consecutive periods
+* MOIC = Total Proceeds / Total Investment
+
+### Sensitivity Tables
+* **Use ODD dimensions** (5×5 or 7×7) — never 4×4 or 6×6. Odd dimensions guarantee a true center cell.
+* **Center cell = base case.** Build the row and column axis values symmetrically around the model's actual assumptions (e.g., if base entry multiple = 10.0x, axis = `[8.0x, 9.0x, 10.0x, 11.0x, 12.0x]`). The center cell's IRR/MOIC MUST then equal the model's actual IRR/MOIC output — this is the proof the table is wired correctly.
+* **Highlight the center cell** — medium-blue fill (`#BDD7EE`) + bold font so the base case is visually anchored.
+* Excel's DATA TABLE function may not work with openpyxl — instead write explicit formulas that reference row/column headers
+* Each cell should show a DIFFERENT value — if all same, formulas aren't varying correctly
+* Use mixed references (e.g., `$A5` for row input, `B$4` for column input)
+
+---
+
+## VERIFICATION CHECKLIST - RUN AFTER COMPLETION
+
+### Run Formula Validation
+```bash
+python /path/to/excel-author/scripts/recalc.py model.xlsx
+```
+Must return success with zero errors.
+
+### Section Balancing
+- [ ] Any sections that must balance (Sources/Uses, Assets/Liabilities) balance exactly
+- [ ] Plug items are calculated correctly as the balancing figure
+- [ ] Amounts that should match across sections are consistent
+
+### Income/Operating Projections
+- [ ] Revenue/top-line builds correctly from drivers or growth rates
+- [ ] All cost and expense items calculated appropriately
+- [ ] Subtotals and totals sum correctly
+- [ ] Margins and ratios are reasonable
+- [ ] Links to assumptions are correct
+
+### Balance Sheet (if applicable)
+- [ ] Assets = Liabilities + Equity (must balance)
+- [ ] All items link to appropriate schedules or roll-forwards
+- [ ] Beginning balances = prior period ending balances
+- [ ] Check row included and shows zero
+
+### Cash Flow (if applicable)
+- [ ] Starts with correct income figure
+- [ ] Non-cash items added/subtracted appropriately
+- [ ] Working capital changes have correct signs
+- [ ] Ending Cash = Beginning Cash + Net Cash Flow

+
+### Supporting Schedules
+- [ ] Roll-forward schedules balance (Beginning + Changes = Ending)
+- [ ] Schedules link correctly to main statements
+- [ ] Calculated items use appropriate drivers
+- [ ] All periods are calculated consistently

+- [ ] Totals sum tranches correctly
+
+### Returns/Output Analysis
+- [ ] Exit/terminal values calculated correctly
+- [ ] All relevant adjustments included
+- [ ] Cash flow signs are correct (negative for investment, positive for proceeds)
+- [ ] IRR/MOIC formulas reference complete ranges
+- [ ] Results are reasonable for the scenario
+
+### Sensitivity Tables (if applicable)
+- [ ] Grid dimensions are ODD (5×5 or 7×7) — there is a true center cell
+- [ ] Row and column axis values are symmetric around the base case (`[base-2Δ, base-Δ, base, base+Δ, base+2Δ]`)
+- [ ] Center cell output equals the model's actual IRR/MOIC — confirms the table is wired correctly
+- [ ] Center cell is highlighted (medium-blue fill `#BDD7EE`, bold font)
+- [ ] Row and column headers contain appropriate input values
+- [ ] Each data cell contains a formula (not hardcoded)
+- [ ] Each data cell shows a DIFFERENT value

+- [ ] No obviously wrong values (negative where should be positive, impossible percentages, etc.)
+- [ ] Key outputs are within reasonable ranges for the type of analysis
+
+---
+
+## COMMON ERRORS TO AVOID
+
+| Error | What Goes Wrong | How to Fix |
+|-------|-----------------|------------|
+| Hardcoding calculated values | Model doesn't update when inputs change | Always use formulas that reference source cells |
+| Wrong cell references after copying | Formulas point to wrong cells | Verify all links, use appropriate $ anchoring |
+| Circular reference errors | Model can't calculate | Use beginning balances for interest-type calcs, break the circle |
+| Sections don't balance | Totals that should match don't | Ensure one item is the plug (calculated as difference) |
+| Negative balances where impossible | Paying/using more than available | Use MAX(0, ...) or MIN functions appropriately |
+| IRR/return errors | Wrong signs or incomplete ranges | Check cash flow signs and ensure formula covers all periods |
+| Sensitivity table shows same value | Formula not varying with inputs | Check cell references - need mixed references ($A5, B$4) |
+| Roll-forwards don't tie | Beginning ≠ prior ending | Verify links between periods |
+| Inconsistent sign conventions | Additions become subtractions or vice versa | Follow template's convention consistently throughout |
+
+---
+
+## WORKING WITH THE USER — SECTION-BY-SECTION CHECKPOINTS
+
+* **If the template structure is unclear**, ask before proceeding
+* **If the user's requirements conflict with the template**, confirm their preference
+* **After completing each major section**, STOP and verify with the user before continuing:
+  - **After Sources & Uses** → show the balanced table, confirm the plug is correct, get sign-off before building the operating model
+  - **After Operating Model / Projections** → show the projected P&L, confirm growth rates and margins look right, get sign-off before the debt schedule
+  - **After Debt Schedule** → show beginning/ending balances and interest, confirm the waterfall logic, get sign-off before returns
+  - **After Returns (IRR/MOIC)** → show the cash flow series and outputs, confirm signs and ranges, get sign-off before sensitivity tables
+  - **After Sensitivity Tables** → show that each cell varies, confirm the base case lands where expected
+* **If errors are found during verification**, fix them before moving to the next section
+* **Show your work** - explain key formulas or assumptions when helpful
+* **Never present a completed model without having checked in at each section** — it's faster to catch a wrong cell reference at the source than to trace it backwards from a broken IRR
+
+---
+
+**This skill produces investment banking-quality LBO models by filling templates with correct formulas, proper formatting, and validated calculations. The skill adapts to any template structure while ensuring financial accuracy and professional presentation standards.**
+
+
+## Data sources — MCP first, web fallback
+
+Many passages below say "use the S&P Kensho MCP / Daloopa MCP / FactSet MCP". Those are commercial financial-data MCPs from the original Cowork plugin context. In Hermes:
+
+- **If you have any structured financial-data MCP configured** (Hermes supports MCP — see `native-mcp` skill), prefer it for point-in-time comps, precedent transactions, and filings.
+- **Otherwise**, fall back to:
+  - `web_search` / `web_extract` against SEC EDGAR (`https://www.sec.gov/cgi-bin/browse-edgar`) for US filings
+  - Company IR pages for press releases, earnings decks
+  - `browser_navigate` for interactive data portals
+  - User-provided data (explicitly ask when the context doesn't have it)
+- **Never fabricate**. If a multiple, precedent, or filing number can't be sourced, flag the cell as `[UNSOURCED]` and surface it to the user.

+
+## Environment
+
+This skill assumes **headless openpyxl** — you are producing an .xlsx file on disk.
+Follow the `excel-author` skill's conventions for cell coloring, formulas, named ranges, and sensitivity tables.
+Recalculate before delivery: `python /path/to/excel-author/scripts/recalc.py ./out/model.xlsx`.
+
+# Merger Model
+
+Build accretion/dilution analysis for M&A transactions. Models pro forma EPS impact, synergy sensitivities, and purchase price allocation. Use when evaluating a potential acquisition, preparing merger consequences analysis for a pitch, or advising on deal terms.
+
+## Workflow
+
+### Step 1: Gather Inputs
+
+**Acquirer:**
+- Company name, current share price, shares outstanding
+- LTM and NTM EPS (GAAP and adjusted)
+- P/E multiple
+- Pre-tax cost of debt, tax rate
+- Cash on balance sheet, existing debt
+
+**Target:**
+- Company name, current share price, shares outstanding (if public)
+- LTM and NTM EPS or net income
+- Enterprise value or equity value
+
+**Deal Terms:**
+- Offer price per share (or premium to current)
+- Consideration mix: % cash vs. % stock
+- New debt raised to fund cash portion
+- Expected synergies (revenue and cost) and phase-in timeline
+- Transaction fees and financing costs
+- Expected close date
+
+### Step 2: Purchase Price Analysis
+
+| Item | Value |
+|------|-------|
+| Offer price per share | |
+| Premium to current | |
+| Equity value | |
+| Plus: net debt assumed | |
+| Enterprise value | |
+| EV / EBITDA implied | |
+| P/E implied | |
+
+### Step 3: Sources & Uses
+
+| Sources | $ | Uses | $ |
+|---------|---|------|---|
+| New debt | | Equity purchase price | |
+| Cash on hand | | Refinance target debt | |
+| New equity issued | | Transaction fees | |
+| | | Financing fees | |
+| **Total** | | **Total** | |
+
+### Step 4: Pro Forma EPS (Accretion / Dilution)
+
+Calculate year-by-year (Year 1-3):
+
+| | Standalone | Pro Forma | Accretion/(Dilution) |
+|---|-----------|-----------|---------------------|
+| Acquirer net income | | | |
+| Target net income | | | |
+| Synergies (after tax) | | | |
+| Foregone interest on cash (after tax) | | | |
+| New debt interest (after tax) | | | |
+| Intangible amortization (after tax) | | | |
+| Pro forma net income | | | |
+| Pro forma shares | | | |
+| **Pro forma EPS** | | | |
+| **Accretion / (Dilution) %** | | | |
+
+### Step 5: Sensitivity Analysis
+
+**Accretion/Dilution vs. Synergies and Offer Premium:**
+
+| | $0M syn | $25M syn | $50M syn | $75M syn | $100M syn |
+|---|---------|----------|----------|----------|-----------|
+| 15% premium | | | | | |
+| 20% premium | | | | | |
+| 25% premium | | | | | |
+| 30% premium | | | | | |
+
+**Accretion/Dilution vs. Cash/Stock Mix:**
+
+| | 100% cash | 75/25 | 50/50 | 25/75 | 100% stock |
+|---|-----------|-------|-------|-------|------------|
+| Year 1 | | | | | |
+| Year 2 | | | | | |
+
+### Step 6: Breakeven Synergies
+
+Calculate the minimum synergies needed for the deal to be EPS-neutral in Year 1.
+
+### Step 7: Output
+
+- Excel workbook with:
+  - Assumptions tab
+  - Sources & uses
+  - Pro forma income statement
+  - Accretion/dilution summary
+  - Sensitivity tables
+  - Breakeven analysis
+- One-page merger consequences summary for pitch book
+
+## Important Notes
+
+- Always show both GAAP and adjusted (cash) EPS where relevant
+- Stock deals: use acquirer's current price for exchange ratio, note dilution from new shares
+- Include purchase price allocation — goodwill and intangible amortization matter for GAAP EPS
+- Synergy phase-in is critical — Year 1 is often only 25-50% of run-rate synergies
+- Don't forget foregone interest income on cash used and new interest expense on debt raised
+- Tax rate on synergies and interest adjustments should match the acquirer's marginal rate
+
+
+## Data sources — MCP first, web fallback

+# pptx-author
+
+Produce a .pptx file on disk using `python-pptx`. Use when you need to deliver a deck as a file artifact, not drive a live PowerPoint session.
+
+Adapted from Anthropic's `pptx-author` and `pitch-deck` skills in [anthropics/financial-services](https://github.com/anthropics/financial-services). The MCP / Office-JS branches of the originals are dropped — this assumes headless Python.
+
+For the broader, already-shipped PowerPoint authoring skill (slides, speaker notes, embeds, media), see the built-in `powerpoint` skill. This skill is a lighter-weight pattern tuned for model-backed decks (pitch decks, IC memos, earnings notes) where every number must trace to a source workbook.
+
+## Output contract
+
+- Write to `./out/<name>.pptx`. Create `./out/` if it does not exist.
+- Return the relative path in your final message.
+
+## Setup
+
+```bash
+pip install "python-pptx>=0.6"
+```
+
+## Core conventions
+
+### One idea per slide
+Title states the takeaway; body supports it. A slide titled "Q3 Revenue" is weak; "Revenue growth accelerated to 14% Y/Y in Q3" is strong.
+
+### Every number traces to the model
+If a figure on a slide came from `./out/model.xlsx`, footnote the sheet and cell.
+
+```
+Revenue: $1,250M  (Source: model.xlsx, Inputs!C3)
+```
+
+Never transcribe numbers from memory or from a summary — open the workbook, read the named range, and bind the deck value to it programmatically when you can.
+
+### Use the firm template when one is mounted
+If `./templates/firm-template.pptx` exists, load it so the deck inherits branded colors, fonts, and master layouts.
+
+```python
+from pptx import Presentation
+from pathlib import Path
+
+template = Path("./templates/firm-template.pptx")
+prs = Presentation(str(template)) if template.exists() else Presentation()
+```
+
+### Charts: PNG-from-model beats native pptx charts
+When fidelity matters (the model's chart styling must match the deck exactly), render the chart to PNG from the source workbook and embed the image. Native `pptx.chart` charts are fragile and often don't match firm conventions.
+
+```python
+from pptx.util import Inches
+slide.shapes.add_picture("./out/charts/football_field.png",
+                         Inches(1), Inches(2),
+                         width=Inches(8))
+```
+
+### No external sends
+This skill writes a file. It never emails, uploads, or posts. Orchestration layers handle delivery.

+Path("./out").mkdir(exist_ok=True)
+prs.save("./out/pitch-aurora.pptx")
+```
+
+## Binding deck numbers to the source workbook
+
+Read named ranges or specific cells from your Excel model so deck numbers never drift.
+
+```python
+from openpyxl import load_workbook
+
+wb = load_workbook("./out/model.xlsx", data_only=True)
+def nr(name):
+    """Resolve a named range to its current computed value."""
+    rng = wb.defined_names[name]
+    sheet, coord = next(rng.destinations)
+    return wb[sheet][coord].value
+
+revenue_fy24 = nr("RevenueFY24")
+implied_mid  = nr("ImpliedSharePriceBase")
+```
+
+Then build deck content using those values:
+```python
+slide.shapes.title.text = f"Implied share price of ${implied_mid:.2f} (base case)"
+```
+
+Remember to recalculate the workbook before reading it — openpyxl only sees computed values if something has already calculated the sheet. Run the recalc helper in the `excel-author` skill first, or open/save through a real Excel session.
+
+## Slide-type checklist for pitch decks
+
+A typical banking pitch deck follows this structure. Not prescriptive, but useful as a starting skeleton:
+
+1. Cover / title
+2. Disclaimer
+3. Table of contents
+4. Situation overview
+5. Company snapshot (the target)
+6. Market / sector context
+7. Valuation summary (football field) — the money slide
+8. Trading comps detail
+9. Precedent transactions detail
+10. DCF summary
+11. Illustrative LBO / sponsor case
+12. Process considerations
+13. Appendix
+
+## When NOT to use this skill
+
+- Users in a live PowerPoint session with an Office MCP available — drive their live doc instead.
+- Non-financial slideware (quarterly all-hands, marketing decks) — use the broader `powerpoint` skill.
+- Decks with heavy animation, transitions, or speaker notes — use the broader `powerpoint` skill.

+Google Chat platform adapter.
+
+Uses Google Cloud Pub/Sub (pull subscription) for inbound events and the
+Google Chat REST API for outbound messages. Pattern parallels Slack Socket
+Mode and Telegram long-polling: no public endpoint required.
+
+Concurrency model
+-----------------
+The Pub/Sub SubscriberClient invokes its message callback in a background
+thread (managed by the client's internal executor). The adapter's
+``handle_message`` coroutine must run on the asyncio event loop, so the
+callback uses ``asyncio.run_coroutine_threadsafe`` with
+``add_done_callback`` (never ``.result()`` — that would block the callback
+thread and saturate the Pub/Sub executor under load).
+
+All outbound Chat REST calls go through ``asyncio.to_thread`` because the
+googleapiclient is synchronous. This keeps the event loop responsive.
+

+
+    Pub/Sub stream   ->  callback thread        ->  asyncio loop

+
+Event type routing
+------------------
+Inbound envelope carries ``type`` in [MESSAGE, ADDED_TO_SPACE, REMOVED_FROM_SPACE,
+CARD_CLICKED]. Only MESSAGE dispatches to the agent. ADDED_TO_SPACE caches the
+bot's resource name (belt-and-suspenders on top of eager resolution in connect()).
+CARD_CLICKED is ACK'd only in v1 (follow-up PR implements interactivity).

+        ``on_processing_complete`` (failure / cancellation).
+
+        IMPORTANT — must place the typing card in the user's thread:

+"""User OAuth helper for the Google Chat gateway adapter.
+
+Google Chat's ``media.upload`` REST endpoint hard-rejects service-account
+authentication:
+
+    "This method doesn't support app authentication with a service
+     account. Authenticate with a user account."
+
+(See https://developers.google.com/workspace/chat/api/reference/rest/v1/media/upload
+and https://developers.google.com/chat/api/guides/auth/users.)
+
+For the bot to deliver native file attachments — the same drag-and-drop
+file widget the user gets when they upload manually — each user must
+grant the bot the ``chat.messages.create`` scope ONCE in their own DM.
+The bot stores per-user refresh tokens and calls ``media.upload`` plus
+the subsequent ``messages.create`` *as the requesting user* whenever a
+file needs sending.
+
+This module is BOTH a CLI tool (driven by the agent via slash commands or
+terminal commands) AND a library imported by ``google_chat.py``:
+
+    Library functions (called from the adapter at runtime):
+        load_user_credentials(email=None) -> Credentials | None
+        refresh_or_none(creds, email=None) -> Credentials | None
+        build_user_chat_service(creds) -> chat_v1.Resource
+        list_authorized_emails() -> List[str]
+
+    CLI commands (driven by the agent through the /setup-files slash
+    command, modeled on skills/productivity/google-workspace/scripts/setup.py):
+        --check                          Exit 0 if auth is valid, else 1
+        --client-secret /path/to.json    Persist OAuth client credentials
+        --auth-url                       Print the OAuth URL for the user
+        --auth-code CODE                 Exchange auth code for token
+        --revoke                         Revoke and delete stored token
+        --install-deps                   Install Python dependencies
+        --email EMAIL                    Scope CLI ops to a specific user
+                                         (defaults to legacy single-user
+                                         mode when omitted)
+
+The flow mirrors the existing google-workspace skill exactly so anyone
+familiar with that flow can read this without surprises.
+
+Token storage layout

+- Per-user tokens (keyed by sender email):
+    ``${HERMES_HOME}/google_chat_user_tokens/<sanitized_email>.json``
+- Legacy single-user token (fallback, untouched for backward compat):
+    ``${HERMES_HOME}/google_chat_user_token.json``
+- Per-user pending OAuth state during /setup-files start → exchange:
+    ``${HERMES_HOME}/google_chat_user_oauth_pending/<sanitized_email>.json``
+- Legacy pending state:
+    ``${HERMES_HOME}/google_chat_user_oauth_pending.json``

+"""Regression tests for MCP server availability in cron jobs.
+
+Background
+==========
+``cron/scheduler.py:run_job()`` constructs ``AIAgent(...)`` directly without
+calling ``discover_mcp_tools()`` — the initialization that CLI and gateway
+paths do at startup. Cron jobs therefore never saw any MCP tools from
+``mcp_servers`` in config.yaml. See #4219.
+
+The fix inserts ``discover_mcp_tools()`` before the ``AIAgent(...)`` call,
+wrapped in try/except so a broken MCP server can't kill an otherwise
+working cron job. ``discover_mcp_tools`` is idempotent — subsequent ticks
+short-circuit on already-connected servers.

+"""Regression tests for TOCTOU-safe credential file writers in ``hermes_cli.auth``.
+
+Background
+==========
+The three writers below used to create a temp file via ``Path.write_text`` /
+``Path.open('w')`` and only ``chmod``'d it to ``0o600`` afterward. Between
+create and chmod the file existed at the process umask (typically ``0o644``),
+briefly exposing OAuth tokens to other local users on multi-user hosts. The
+fix switches them to ``os.open(O_EXCL, mode=0o600)`` + ``os.fdopen`` +
+``fsync`` so the file is atomic at ``0o600`` on creation. Mirrors the fixes
+shipped for ``agent/google_oauth.py`` (#19673) and ``tools/mcp_oauth.py``
+(#21148).
+
+These tests stay green only while the token file and its parent directory
+end up at ``0o600`` / ``0o700`` after every write. POSIX-only — the mode-bit
+enforcement does not exist on Windows.

+"""Regression test: ``hermes mcp add --command`` must not clobber the
+top-level ``args.command`` subparser dest.
+
+The top-level argparse parser uses ``dest="command"`` for its subparsers
+(``hermes_cli/_parser.py``).  The dispatcher in ``hermes_cli/main.py``
+reads ``args.command`` to decide which command to run; if it is ``None``
+it falls through to interactive chat.
+
+The ``mcp add`` subparser exposes a ``--command`` flag (the stdio command
+for an MCP server, e.g. ``npx``).  Without an explicit ``dest=``, argparse
+derives the dest from the flag name and writes ``args.command = None``
+when the flag is omitted, overwriting the top-level ``"mcp"`` value.  As a
+result, ``hermes mcp add foo --url ...`` silently launches chat instead
+of registering an MCP server.
+
+The fix: declare the flag with ``dest="mcp_command"``.  The CLI flag name
+is unchanged; only the in-memory attribute moves.
+
+We replicate the relevant parser shape here rather than importing the
+real builder, mirroring ``test_argparse_flag_propagation.py`` and
+``test_subparser_routing_fallback.py``.

+"""Regression tests for ``MCPServerTask.run`` + ``asyncio.CancelledError``.

+Background
+==========
+On Python 3.11+, ``asyncio.CancelledError`` inherits from ``BaseException``
+rather than ``Exception``, so a bare ``except Exception`` does NOT catch it.
+``MCPServerTask.run`` had a broad ``except Exception`` around the transport
+loop which meant a task cancellation (gateway restart, explicit
+``task.cancel()``) caused the reconnect loop to exit silently — the MCP
+server stayed dead until Hermes was restarted. See #9930.
+
+The fix adds an explicit ``except asyncio.CancelledError: raise`` BEFORE
+the broad catch so cancellation propagates cleanly to asyncio's task
+machinery and ``MCPServerTask.shutdown()``'s ``await self._task`` completes
+without hanging the reconnect loop.

+"""Tests for OAuth server metadata persistence across process restarts.
+
+Covers:
+- :class:`HermesTokenStorage` ``.meta.json`` roundtrip (save / load / remove)
+- The production manager provider
+  (:class:`tools.mcp_oauth_manager.HermesMCPOAuthProvider`) restoring metadata
+  on cold-load init and persisting metadata at the end of ``async_auth_flow``.
+
+Context
+=======
+The MCP SDK discovers OAuth server metadata (``token_endpoint``, etc.)
+on-demand and keeps it in memory only. Without disk persistence a restart
+forces the SDK to fall back to guessing ``{server_url}/token``, which returns
+404 on most real providers and triggers a full browser re-auth even when the
+refresh token is still valid. These tests lock in the disk persistence
+layer so refresh across restarts stays quiet.

+"""Regression tests for SSE transport in ``MCPServerTask._run_http``.

+
+1. ``sse_read_timeout`` is set to 300s (not the tool timeout). SSE servers
+   commonly hold the stream idle for minutes between events; a 60s read
+   timeout drops the connection after the first slow stretch. Original
+   observation: Router Teamwork / Supermemory on Cloudflare Workers dropping
+   at ~60s idle.
+
+2. OAuth auth is forwarded to ``sse_client`` when configured. Previously the
+   code built ``_oauth_auth`` but never passed it to the SSE path, so SSE MCP
+   servers behind OAuth 2.1 PKCE would silently fail with 401s.

+"""Regression tests for capability-gated MCP utility schema registration.
+
+Background
+==========
+For every connected MCP server, hermes-agent used to register four "utility"
+tool schemas (``mcp_<server>_list_resources``, ``read_resource``,
+``list_prompts``, ``get_prompt``) regardless of whether the server actually
+advertises those capabilities. The old gate used ``hasattr(server.session,
+method)`` which always returned True because ``mcp.ClientSession`` defines
+all four methods on the class — independent of what the remote server
+supports.
+
+Tools-only servers like ``@upstash/context7-mcp`` advertise
+``{\"tools\": {\"listChanged\": true}}`` in their ``initialize`` response —
+no ``prompts`` or ``resources`` keys — and they return JSON-RPC
+``-32601 Method not found`` for ``prompts/list``, ``prompts/get``,
+``resources/list``, ``resources/read``. The model would try the stubs,
+get the error, and incorrectly conclude the MCP server was broken.
+
+The fix captures the ``InitializeResult`` from
+``await session.initialize()`` into ``MCPServerTask.initialize_result``
+and gates utility schema registration on the advertised
+``capabilities.resources`` / ``capabilities.prompts`` sub-objects. See
+#18051 for the reporter's repro (Context7) and analysis.

+"""Brave Search web search provider (free tier).
+
+Brave Search's Data-for-Search API offers a free tier (2,000 queries/mo at the
+time of writing) after signing up at https://brave.com/search/api/.  This
+provider implements ``WebSearchProvider`` only — the Data-for-Search endpoint
+returns search results, it does not extract/crawl arbitrary URLs.
+
+Configuration::
+
+    # ~/.hermes/.env
+    BRAVE_SEARCH_API_KEY=your-subscription-token
+
+    # ~/.hermes/config.yaml
+    web:
+      search_backend: "brave-free"
+      extract_backend: "firecrawl"    # pair with an extract provider if needed
+
+The API uses the ``X-Subscription-Token`` header.  Free-tier keys are rate
+limited (1 qps) and capped at 2k queries/month; see the Brave dashboard for
+current quotas.

+## Env-Driven Auto-Configuration
+
+Most users set up a platform by dropping env vars into `~/.hermes/.env` rather than editing `config.yaml`. The `env_enablement_fn` hook lets your plugin pick those env vars up **before** the adapter is constructed, so `hermes gateway status`, `get_connected_platforms()`, and cron delivery see the correct state without instantiating the platform SDK.
+
+```python
+def _env_enablement() -> dict | None:
+    """Seed PlatformConfig.extra from env vars.
+
+    Called by the platform registry during load_gateway_config().
+    Return None when the platform isn't minimally configured — the
+    caller then skips auto-enabling. Return a dict to seed extras.
+
+    The special 'home_channel' key is extracted and becomes a proper
+    HomeChannel dataclass on the PlatformConfig; every other key is
+    merged into PlatformConfig.extra.
+    """
+    token = os.getenv("MY_PLATFORM_TOKEN", "").strip()
+    channel = os.getenv("MY_PLATFORM_CHANNEL", "").strip()
+    if not (token and channel):
+        return None
+    seed = {"token": token, "channel": channel}
+    home = os.getenv("MY_PLATFORM_HOME_CHANNEL")
+    if home:
+        seed["home_channel"] = {
+            "chat_id": home,
+            "name": os.getenv("MY_PLATFORM_HOME_CHANNEL_NAME", "Home"),
+        }
+    return seed
+
+
+def register(ctx):
+    ctx.register_platform(
+        name="my_platform",
+        label="My Platform",
+        adapter_factory=lambda cfg: MyPlatformAdapter(cfg),
+        check_fn=check_requirements,
+        validate_config=validate_config,
+        env_enablement_fn=_env_enablement,
+        # ... other fields
+    )
+```
+
+## Cron Delivery
+
+To let `deliver=my_platform` cron jobs route to a configured home channel, set `cron_deliver_env_var` to the env var name that holds the default chat/room/channel ID:
+
+```python
+ctx.register_platform(
+    name="my_platform",
+    ...
+    cron_deliver_env_var="MY_PLATFORM_HOME_CHANNEL",
+)
+```
+
+The scheduler reads this env var when resolving the home target for `deliver=my_platform` jobs, and also treats the platform as a valid cron target in `_KNOWN_DELIVERY_PLATFORMS`-style checks. If your `env_enablement_fn` seeds a `home_channel` dict (see above), that takes precedence — `cron_deliver_env_var` is the fallback for cron jobs that run before env seeding.
+
+## Surfacing Env Vars in `hermes config`
+
+`hermes_cli/config.py` scans `plugins/platforms/*/plugin.yaml` at import time and auto-populates `OPTIONAL_ENV_VARS` from `requires_env` and (optional) `optional_env` blocks. Use the rich-dict form to contribute proper descriptions, prompts, password flags, and URLs — the CLI setup UI picks them up for free.
+

+  - name: MY_PLATFORM_ALLOWED_USERS
+    description: "Comma-separated user IDs allowed to talk to the bot"
+    prompt: "Allowed users (comma-separated)"
+    password: false
+```
+
+**Supported dict keys:** `name` (required), `description`, `prompt`, `url`, `password` (bool; auto-detected from `*_TOKEN` / `*_SECRET` / `*_KEY` / `*_PASSWORD` / `*_JSON` suffix when omitted), `category` (defaults to `"messaging"`).
+
+Bare-string entries (`- MY_PLATFORM_TOKEN`) still work — they get a generic description auto-derived from the plugin's `label`. If a hardcoded entry for the same var already exists in `OPTIONAL_ENV_VARS`, it wins (back-compat); the plugin.yaml form acts as the fallback.

+### `transform_llm_output`
+
+Fires **once per turn** after the tool-calling loop completes and the model has produced a final response, **before** that response is delivered to the user (CLI, gateway, or programmatic caller). Lets a plugin rewrite the assistant's final text using classical-programming methods — no extra inference tokens burned on SOUL flavor text or a skill-driven transform.
+
+**Callback signature:**
+
+```python
+def my_callback(
+    response_text: str,
+    session_id: str,
+    model: str,
+    platform: str,
+    **kwargs,
+) -> str | None:
+```
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `response_text` | `str` | The assistant's final response text for this turn. |
+| `session_id` | `str` | Session ID for this conversation (may be empty for one-shot runs). |
+| `model` | `str` | Model name that produced the response (e.g. `anthropic/claude-sonnet-4.6`). |
+| `platform` | `str` | Delivery platform (`cli`, `telegram`, `discord`, …; empty when unset). |
+
+**Return value:** Non-empty `str` to replace the response text, `None` or empty string to leave it unchanged. **First non-empty string wins** when multiple plugins register — mirroring `transform_tool_result`.
+
+**Use cases:** Apply a personality/vocabulary transform (pirate-speak, Spongebob), redact user-specific identifiers from the final text, append a project-specific signature footer, enforce a house style guide without burning tokens on SOUL instructions.
+
+```python
+import os, re
+
+def spongebob(response_text, **kwargs):
+    if os.environ.get("SPONGEBOB_MODE") != "on":
+        return None  # pass through unchanged
+    return re.sub(r"!", "!! Tartar sauce!", response_text)
+
+def register(ctx):
+    ctx.register_hook("transform_llm_output", spongebob)
+```
+
+The hook is guarded on a non-empty, non-interrupted response — it will not fire on stop-button interrupts or empty turns. Exceptions are logged as warnings and do not break agent execution.
+
+---
+
 ## Shell Hooks
 
 Declare shell-script hooks in your `cli-config.yaml` and Hermes will run them as subprocesses whenever the corresponding plugin-hook event fires — in both CLI and gateway sessions. No Python plugin authoring required.

Run `hermes kanban specify <id>` to have the auxiliary LLM expand a triage task into a concrete spec (title + body with goal, approach, acceptance criteria) and promote it to `todo` in one shot; `--all` sweeps every triage task at once. Configure which model runs the specifier under `auxiliary.triage_specifier` in `config.yaml`.
 - Cards show the task id, title, priority badge, tenant tag, assigned profile, comment/link counts, a **progress pill** (`N/M` children done when the task has dependents), and "created N ago". A per-card checkbox enables multi-select.
 - **Per-profile lanes inside Running** — toolbar checkbox toggles sub-grouping of the Running column by assignee.
 - **Live updates via WebSocket** — the plugin tails the append-only `task_events` table on a short poll interval; the board reflects changes the instant any profile (CLI, gateway, or another dashboard tab) acts. Reloads are debounced so a burst of events triggers a single refetch.

 # Nous Tool Gateway
 
-:::tip Get Started
-The Tool Gateway is included with paid Nous Portal subscriptions. **[Manage your subscription →](https://portal.nousresearch.com/manage-subscription)**
-:::
+**One subscription. Every tool built in.**
 
-The **Tool Gateway** lets paid [Nous Portal](https://portal.nousresearch.com) subscribers use web search, image generation, text-to-speech, and browser automation through their existing subscription — no need to sign up for separate API keys from Firecrawl, FAL, OpenAI, or Browser Use.
+The Tool Gateway is included with every paid [Nous Portal](https://portal.nousresearch.com) subscription. It routes Hermes' tool calls — web search, image generation, text-to-speech, and cloud browser automation — through infrastructure Nous already runs, so you don't have to sign up with Firecrawl, FAL, OpenAI, Browser Use, or anyone else just to make your agent useful.
 
-## What's Included
+<div style={{display: 'flex', gap: '1rem', flexWrap: 'wrap', margin: '1.5rem 0'}}>
+  <a href="https://portal.nousresearch.com/manage-subscription" style={{background: 'var(--ifm-color-primary)', color: 'white', padding: '0.75rem 1.5rem', borderRadius: '6px', textDecoration: 'none', fontWeight: 'bold'}}>Start or manage subscription →</a>
+</div>
 
-| Tool | What It Does | Direct Alternative |
-|------|--------------|--------------------|
-| **Web search & extract** | Search the web and extract page content via Firecrawl | `FIRECRAWL_API_KEY`, `EXA_API_KEY`, `PARALLEL_API_KEY`, `TAVILY_API_KEY` |
-| **Image generation** | Generate images via FAL (9 models: FLUX 2 Klein/Pro, GPT-Image 1.5/2, Nano Banana Pro, Ideogram V3, Recraft V4 Pro, Qwen, Z-Image Turbo) | `FAL_KEY` |
-| **Text-to-speech** | Convert text to speech via OpenAI TTS | `VOICE_TOOLS_OPENAI_KEY`, `ELEVENLABS_API_KEY` |
-| **Browser automation** | Control cloud browsers via Browser Use | `BROWSER_USE_API_KEY`, `BROWSERBASE_API_KEY` |
+## What's included
 
-All four tools bill to your Nous subscription. You can enable any combination — for example, use the gateway for web and image generation while keeping your own ElevenLabs key for TTS.
+| | Tool | What you get |
+|---|---|---|
+| 🔍 | **Web search & extract** | Agent-grade web search and full-page extraction via Firecrawl. No rate limits to worry about — the gateway handles scaling. |
+| 🎨 | **Image generation** | Nine models under one endpoint: **FLUX 2 Klein 9B**, **FLUX 2 Pro**, **Z-Image Turbo**, **Nano Banana Pro** (Gemini 3 Pro Image), **GPT Image 1.5**, **GPT Image 2**, **Ideogram V3**, **Recraft V4 Pro**, **Qwen Image**. Pick per-generation with a flag, or let Hermes default to FLUX 2 Klein. |
+| 🔊 | **Text-to-speech** | OpenAI TTS voices wired into the `text_to_speech` tool. Drop voice notes into Telegram, generate audio for pipelines, narrate anything. |
+| 🌐 | **Cloud browser automation** | Headless Chromium sessions via Browser Use. `browser_navigate`, `browser_click`, `browser_type`, `browser_vision` — all the agent-driving primitives, no Browserbase account required. |
 
-## Eligibility
+All four are pay-as-you-use billed against your Nous subscription. Use any combination — run the gateway for web and images while keeping your own ElevenLabs key for TTS, or route everything through Nous.
 
-The Tool Gateway is available to **paid** [Nous Portal](https://portal.nousresearch.com/manage-subscription) subscribers. Free-tier accounts do not have access — [upgrade your subscription](https://portal.nousresearch.com/manage-subscription) to unlock it.
+## Why it's here
 
-To check your status:
+Building an agent that can actually *do things* means stitching together 5+ API subscriptions — each with their own signup, rate limits, billing, and quirks. The gateway collapses that into one account:
+
+- **One bill.** Pay Nous; we handle the rest.
+- **One signup.** No Firecrawl, FAL, Browser Use, or OpenAI audio accounts to manage.
+- **One key.** Your Nous Portal OAuth covers every tool.
+- **Same quality.** Same backends the direct-key route uses — just fronted by us.
+
+Bring your own keys anytime — per-tool, whenever you want to. The gateway isn't a lock-in, it's a shortcut.
+
+## Get started
+
+```bash
+hermes model          # Pick Nous Portal as your provider
+```
+
+When you select Nous Portal, Hermes offers to turn on the Tool Gateway. Accept, and you're done — every supported tool is live on the next run.
+
+Check what's active at any time:
 
 ```bash
 hermes status
 ```
 
-Look for the **Nous Tool Gateway** section. It shows which tools are active via the gateway, which use direct keys, and which aren't configured.
-
-## Enabling the Tool Gateway
-
-### During model setup
-
-When you run `hermes model` and select Nous Portal as your provider, Hermes automatically offers to enable the Tool Gateway:
+You'll see a section like:
 
 ```
-Your Nous subscription includes the Tool Gateway.
-
-  The Tool Gateway gives you access to web search, image generation,
-  text-to-speech, and browser automation through your Nous subscription.
-  No need to sign up for separate API keys — just pick the tools you want.
-
-  ○ Web search & extract (Firecrawl) — not configured
-  ○ Image generation (FAL) — not configured
-  ○ Text-to-speech (OpenAI TTS) — not configured
-  ○ Browser automation (Browser Use) — not configured
-
-  ● Enable Tool Gateway
-  ○ Skip
+◆ Nous Tool Gateway
+  Nous Portal     ✓ managed tools available
+  Web tools       ✓ active via Nous subscription
+  Image gen       ✓ active via Nous subscription
+  TTS             ✓ active via Nous subscription

-Select **Enable Tool Gateway** and you're done.
+Tools marked "active via Nous subscription" are going through the gateway. Anything else is using your own keys.
 
-If you already have direct API keys for some tools, the prompt adapts — you can enable the gateway for all tools (your existing keys are kept in `.env` but not used at runtime), enable only for unconfigured tools, or skip entirely.
+## Eligibility
 
-### Via `hermes tools`
+The Tool Gateway is a **paid-subscription** feature. Free-tier Nous accounts can use Portal for inference but don't include managed tools — [upgrade your plan](https://portal.nousresearch.com/manage-subscription) to unlock the gateway.
 
-You can also enable the gateway tool-by-tool through the interactive tool configuration:
+## Mix and match
+
+The gateway is per-tool. Turn it on for just what you want:
+
+- **All tools through Nous** — easiest; one subscription, done.
+- **Gateway for web + images, bring your own TTS** — keep your ElevenLabs voice, let Nous handle the rest.
+- **Gateway only for things you don't have keys for** — "I already pay for Browserbase, but I don't want a Firecrawl account" works fine.
+
+Switch any tool at any time via:
 
 ```bash
-hermes tools
+hermes tools          # Interactive picker for each tool category
 ```
 
-Select a tool category (Web, Browser, Image Generation, or TTS), then choose **Nous Subscription** as the provider. This sets `use_gateway: true` for that tool in your config.
+Select the tool, pick **Nous Subscription** as the provider (or any direct provider you prefer). No config editing required.
 
-### Manual configuration
+## Using individual image models
 
-Set the `use_gateway` flag directly in `~/.hermes/config.yaml`:
+Image generation defaults to FLUX 2 Klein 9B for speed. Override per-call by passing the model ID to the `image_generate` tool:
+
+| Model | ID | Best for |
+|---|---|---|
+| FLUX 2 Klein 9B | `fal-ai/flux-2/klein/9b` | Fast, good default |
+| FLUX 2 Pro | `fal-ai/flux-2/pro` | Higher fidelity FLUX |
+| Z-Image Turbo | `fal-ai/z-image/turbo` | Stylized, fast |
+| Nano Banana Pro | `fal-ai/gemini-3-pro-image` | Google Gemini 3 Pro Image |
+| GPT Image 1.5 | `fal-ai/gpt-image-1/5` | OpenAI image gen, text+image |
+| GPT Image 2 | `fal-ai/gpt-image-2` | OpenAI latest |
+| Ideogram V3 | `fal-ai/ideogram/v3` | Strong prompt adherence + typography |
+| Recraft V4 Pro | `fal-ai/recraft/v4/pro` | Vector-style, graphic design |
+| Qwen Image | `fal-ai/qwen-image` | Alibaba multimodal |
+
+The set evolves — `hermes tools` → Image Generation shows the current live list.

+
+## Configuration reference
+
+Most users never need to touch this — `hermes model` and `hermes tools` cover every workflow interactively. This section is for writing config.yaml directly or scripting setups.
+
+### Per-tool `use_gateway` flag
+
+Each tool's config block takes a `use_gateway` boolean:
 
 ```yaml
 web:
@@ -93,95 +129,48 @@ browser:
   use_gateway: true
 ```
 
-## How It Works
+Precedence: `use_gateway: true` routes through Nous regardless of any direct keys in `.env`. `use_gateway: false` (or absent) uses direct keys if available and only falls back to the gateway when none exist.
 
-When `use_gateway: true` is set for a tool, the runtime routes API calls through the Nous Tool Gateway instead of using direct API keys:
-
-1. **Web tools** — `web_search` and `web_extract` use the gateway's Firecrawl endpoint
-2. **Image generation** — `image_generate` uses the gateway's FAL endpoint
-3. **TTS** — `text_to_speech` uses the gateway's OpenAI Audio endpoint
-4. **Browser** — `browser_navigate` and other browser tools use the gateway's Browser Use endpoint
-
-The gateway authenticates using your Nous Portal credentials (stored in `~/.hermes/auth.json` after `hermes model`).
-
-### Precedence
-
-Each tool checks `use_gateway` first:
-
-- **`use_gateway: true`** → route through the gateway, even if direct API keys exist in `.env`
-- **`use_gateway: false`** (or absent) → use direct API keys if available, fall back to gateway only when no direct keys exist
-
-This means you can switch between gateway and direct keys at any time without deleting your `.env` credentials.
-
-## Switching Back to Direct Keys
-
-To stop using the gateway for a specific tool:
-
-```bash
-hermes tools    # Select the tool → choose a direct provider
-```
-
-Or set `use_gateway: false` in config:
+### Disabling the gateway
 
 ```yaml
 web:
-  backend: firecrawl
-  use_gateway: false  # Now uses FIRECRAWL_API_KEY from .env
+  use_gateway: false   # Hermes now uses FIRECRAWL_API_KEY from .env
 ```
 
-When you select a non-gateway provider in `hermes tools`, the `use_gateway` flag is automatically set to `false` to prevent contradictory config.
+`hermes tools` automatically clears the flag when you pick a non-gateway provider, so this usually happens for you.
 
-## Checking Status
+### Self-hosted gateway (advanced)
+
+Running your own Nous-compatible gateway? Override endpoints in `~/.hermes/.env`:
 
 ```bash
-hermes status
+TOOL_GATEWAY_DOMAIN=your-domain.example.com
+TOOL_GATEWAY_SCHEME=https
+TOOL_GATEWAY_USER_TOKEN=your-token        # normally auto-populated from Portal login
+FIRECRAWL_GATEWAY_URL=https://...         # override one endpoint specifically
 ```
 
-The **Nous Tool Gateway** section shows:
-
-```
-◆ Nous Tool Gateway
-  Nous Portal   ✓ managed tools available
-  Web tools       ✓ active via Nous subscription
-  Image gen       ✓ active via Nous subscription
-  TTS             ✓ active via Nous subscription
-  Browser         ○ active via Browser Use key
-  Modal           ○ available via subscription (optional)
-```
-
-Tools marked "active via Nous subscription" are routed through the gateway. Tools with their own keys show which provider is active.
-
-## Advanced: Self-Hosted Gateway
-
-For self-hosted or custom gateway deployments, you can override the gateway endpoints via environment variables in `~/.hermes/.env`:
-
-```bash
-TOOL_GATEWAY_DOMAIN=nousresearch.com     # Base domain for gateway routing
-TOOL_GATEWAY_SCHEME=https                 # HTTP or HTTPS (default: https)
-TOOL_GATEWAY_USER_TOKEN=your-token        # Auth token (normally auto-populated)
-FIRECRAWL_GATEWAY_URL=https://...         # Override for the Firecrawl endpoint specifically
-```
-
-These env vars are always visible in the configuration regardless of subscription status — they're useful for custom infrastructure setups.
+These knobs exist for custom infrastructure setups (enterprise deployments, dev environments). Regular subscribers never set them.
 
 ## FAQ
 
-### Do I need to delete my existing API keys?
+### Does it work with Telegram / Discord / the other messaging gateways?
 
-No. When `use_gateway: true` is set, the runtime skips direct API keys and routes through the gateway. Your keys stay in `.env` untouched. If you later disable the gateway, they'll be used again automatically.
+Yes. Tool Gateway operates at the tool-execution layer, not the CLI. Every interface that can call a tool — CLI, Telegram, Discord, Slack, IRC, Teams, the API server, anything — benefits from it transparently.
 
-### Can I use the gateway for some tools and direct keys for others?
+### What happens if my subscription expires?
 
-Yes. The `use_gateway` flag is per-tool. You can mix and match — for example, gateway for web and image generation, your own ElevenLabs key for TTS, and Browserbase for browser automation.
+Tools routed through the gateway stop working until you renew or swap in direct API keys via `hermes tools`. Hermes shows a clear error pointing at the portal.
 
-### What if my subscription expires?
+### Can I see usage or costs per tool?
 
-Tools that were routed through the gateway will stop working until you [renew your subscription](https://portal.nousresearch.com/manage-subscription) or switch to direct API keys via `hermes tools`.
+Yes — the [Nous Portal dashboard](https://portal.nousresearch.com) breaks usage down by tool so you can see what's driving your bill.
 
-### Does the gateway work with the messaging gateway?
+### Is Modal (serverless terminal) included?
 
-Yes. The Tool Gateway routes tool API calls regardless of whether you're using the CLI, Telegram, Discord, or any other messaging platform. It operates at the tool runtime level, not the entry point level.
+Modal is available as an **optional add-on** through the Nous subscription, not part of the default Tool Gateway bundle. Configure it via `hermes setup terminal` or directly in `config.yaml` when you want a remote sandbox for shell execution.
 
-### Is Modal included?
+### Do I need to delete my existing API keys when I enable the gateway?
 
-Modal (serverless terminal backend) is available as an optional add-on through the Nous subscription. It's not enabled by the Tool Gateway prompt — configure it separately via `hermes setup terminal` or in `config.yaml`.
+No — keep them in `.env`. When `use_gateway: true`, Hermes skips direct keys and uses the gateway. Flip the flag back to `false` and your keys become the source again. The gateway isn't a lock-in.

+description: "Set up Hermes Agent as a Google Chat bot using Cloud Pub/Sub"
+---
+
+# Google Chat Setup
+
+Connect Hermes Agent to Google Chat as a bot. The integration uses Cloud Pub/Sub
+pull subscriptions for inbound events and the Chat REST API for outbound messages.
+Equivalent ergonomics to Slack Socket Mode or Telegram long-polling: your Hermes
+process does not need a public URL, a tunnel, or a TLS certificate. It connects,
+authenticates, and listens on a subscription — the same way a Telegram bot listens
+on a token.
+
+:::note Workspace edition
+Google Chat is part of Google Workspace. You can use this integration with a
+personal Workspace (`@yourdomain.com` registered through Google) or a work
+Workspace where you have the Admin rights to publish an app. Gmail-only accounts
+cannot host Chat apps.
+:::
+
+## Overview
+
+| Component | Value |
+|-----------|-------|
+| **Libraries** | `google-cloud-pubsub`, `google-api-python-client`, `google-auth` |
+| **Inbound transport** | Cloud Pub/Sub pull subscription (no public endpoint) |
+| **Outbound transport** | Chat REST API (`chat.googleapis.com`) |
+| **Authentication** | Service Account JSON with `roles/pubsub.subscriber` on the subscription |
+| **User identification** | Chat resource names (`users/{id}`) + email |
+
+---
+
+## Step 1: Create or pick a GCP project
+
+You need a Google Cloud project to host the Pub/Sub topic. If you don't have one,
+create it at [console.cloud.google.com](https://console.cloud.google.com) —
+personal accounts get a free tier that easily covers bot traffic.
+
+Note the project ID (e.g., `my-chat-bot-123`). You'll use it in every subsequent
+step.
+
+---
+
+## Step 2: Enable two APIs
+
+In the console, go to **APIs & Services → Library** and enable:
+
+- **Google Chat API**
+- **Cloud Pub/Sub API**
+
+Both are free for the volumes a personal bot generates.
+
+---
+
+## Step 3: Create a Service Account
+
+**IAM & Admin → Service Accounts → Create Service Account.**
+
+- Name: `hermes-chat-bot`
+- Skip the "Grant this service account access to project" step. IAM on the specific
+  subscription is all you need — do **NOT** grant project-level Pub/Sub roles.
+
+After creation, open the SA, go to **Keys → Add Key → Create new key → JSON** and
+download the file. Save it somewhere only Hermes can read (e.g.,
+`~/.hermes/google-chat-sa.json`, `chmod 600`).
+
+:::caution There is NO "Chat Bot Caller" role
+A common mistake is to search for a Chat-specific IAM role and grant it at the
+project level. That role doesn't exist. Chat bot authority comes from being
+installed in a space, not from IAM. All your SA needs is Pub/Sub subscriber on
+the subscription you create in the next step.
+:::
+
+---
+
+## Step 4: Create the Pub/Sub topic and subscription
+
+**Pub/Sub → Topics → Create topic.**
+
+- Topic ID: `hermes-chat-events`
+- Leave the defaults for everything else.
+
+After creation, the topic's detail page has a **Subscriptions** tab. Create one:
+
+- Subscription ID: `hermes-chat-events-sub`
+- Delivery type: **Pull**
+- Message retention: **7 days** (so backlog survives a hermes restart)
+- Leave the rest default.
+
+---
+
+## Step 5: IAM binding on the topic (critical)
+
+On the **topic** (not the subscription), add an IAM principal:
+
+- Principal: `chat-api-push@system.gserviceaccount.com`
+- Role: `Pub/Sub Publisher`
+
+Without this, Google Chat cannot publish events to your topic and your bot will
+never receive anything.
+
+---
+
+## Step 6: IAM binding on the subscription
+
+On the **subscription**, add your own Service Account as a principal:
+
+- Principal: `hermes-chat-bot@<your-project>.iam.gserviceaccount.com`
+- Role: `Pub/Sub Subscriber`
+
+Also grant `Pub/Sub Viewer` on the same subscription — Hermes calls
+`subscription.get()` at startup as a reachability check.
+
+---
+
+## Step 7: Configure the Chat app
+
+Go to **APIs & Services → Google Chat API → Configuration**.
+
+- **App name**: whatever you want users to see ("Hermes" is reasonable).
+- **Avatar URL**: any public PNG (Google has some defaults).
+- **Description**: a short sentence shown in the app directory.
+- **Functionality**: enable **Receive 1:1 messages** and **Join spaces and group
+  conversations**.
+- **Connection settings**: select **Cloud Pub/Sub**, enter the topic name
+  `projects/<your-project>/topics/hermes-chat-events`.
+- **Visibility**: restrict to your workspace (or specific users) — do not publish
+  to everyone while you're testing.
+
+Save.
+
+---
+
+## Step 8: Install the bot in a test space
+
+Open Google Chat in a browser. Start a DM with your app by searching for its name
+in the **+ New Chat** menu. The first time you message it, Google sends an
+`ADDED_TO_SPACE` event that Hermes uses to cache the bot's own `users/{id}` for
+self-message filtering.
+
+---
+
+## Step 9: Configure Hermes
+
+Add the Google Chat section to `~/.hermes/.env`:
+
+```bash
+# Required
+GOOGLE_CHAT_PROJECT_ID=my-chat-bot-123
+GOOGLE_CHAT_SUBSCRIPTION_NAME=projects/my-chat-bot-123/subscriptions/hermes-chat-events-sub
+GOOGLE_CHAT_SERVICE_ACCOUNT_JSON=/home/you/.hermes/google-chat-sa.json
+
+# Authorization — paste the emails of people allowed to talk to the bot
+GOOGLE_CHAT_ALLOWED_USERS=you@yourdomain.com,coworker@yourdomain.com
+
+# Optional
+GOOGLE_CHAT_HOME_CHANNEL=spaces/AAAA...         # default delivery destination for cron jobs
+GOOGLE_CHAT_MAX_MESSAGES=1                      # Pub/Sub FlowControl; 1 serializes commands per session
+GOOGLE_CHAT_MAX_BYTES=16777216                  # 16 MiB — cap on in-flight message bytes
+```
+
+The project ID also falls back to `GOOGLE_CLOUD_PROJECT`, and the SA path falls
+back to `GOOGLE_APPLICATION_CREDENTIALS` — use whichever convention you prefer.
+
+Install Hermes with the optional dependencies:
+
+```bash
+pip install 'hermes-agent[google_chat]'
+```
+
+Start the gateway:
+
+```bash
+hermes gateway
+```
+
+You should see a log line like:
+
+```
+[GoogleChat] Connected; project=my-chat-bot-123, subscription=<redacted>,
+             bot_user_id=users/XXXX, flow_control(msgs=1, bytes=16777216)
+```
+
+Send "hola" in the test DM. The bot posts a "Hermes is thinking…" marker, then
+edits that same message in place with the real response — no "message deleted"
+tombstones.
+
+---
+
+## Formatting and capabilities
+
+Google Chat renders a limited markdown subset:
+
+| Supported | Not supported |
+|-----------|---------------|
+| `*bold*`, `_italic_`, `~strike~`, `` `code` `` | Headings, lists |
+| Inline images via URL | Interactive Card v2 buttons (v1 of this gateway) |
+| Native file attachments (after `/setup-files` — see Step 10) | Native voice notes / circular video notes |
+
+The agent's system prompt includes a Google Chat–specific hint so it knows these
+limits and avoids formatting that won't render.
+
+Message size limit: 4000 characters per message. Longer agent responses are
+automatically split across multiple messages.
+
+Thread support: when a user replies inside a thread, Hermes detects the
+`thread.name` and posts its reply in the same thread, so each thread gets a
+separate Hermes session.
+
+---
+
+## Step 10: Native attachment delivery (optional)
+
+Out of the box the bot can post text, inline images via URL, and download cards
+for audio/video/documents. To deliver **native** Chat attachments — the same
+file widget you get when a human drags-and-drops a file — each user authorizes
+the bot once via a per-user OAuth flow.
+
+### Why a separate flow
+
+Google Chat's `media.upload` endpoint hard-rejects service-account auth:
+
+> This method doesn't support app authentication with a service account.
+> Authenticate with a user account.
+
+There's no IAM role or scope that fixes this. The endpoint only accepts user
+credentials. So the bot has to act *as a user* whenever it uploads a file —
+specifically, as the user who asked for the file.
+
+### One-time host setup
+
+1. Go to **APIs & Services → Credentials** in the same GCP project.
+2. **Create credentials → OAuth client ID → Desktop app**.
+3. Download the JSON. Move it onto the host that runs Hermes.
+4. On the host, register the client with Hermes:
+
+```bash
+python -m gateway.platforms.google_chat_user_oauth \
+    --client-secret /path/to/client_secret.json
+```
+
+That writes `~/.hermes/google_chat_user_client_secret.json`. This is shared
+infrastructure — it identifies the OAuth *app*, not any individual user. One
+file per host is enough no matter how many users authorize later.
+
+### Per-user authorization (in chat)
+
+Each user runs the flow once, in their own DM with the bot:
+
+1. They send `/setup-files` to the bot. It replies with status and the next
+   step.
+2. They send `/setup-files start`. The bot replies with an OAuth URL.
+3. They open the URL, click **Allow**, and watch the browser fail to load
+   `http://localhost:1/?...&code=...`. That failure is expected — the auth
+   code is in the URL bar.
+4. They copy the failed URL (or just the `code=...` value) and paste it back
+   into chat as `/setup-files <PASTED_URL>`. The bot exchanges it for a
+   refresh token.
+
+The token lands at `~/.hermes/google_chat_user_tokens/<sanitized_email>.json`.
+Subsequent file requests in that user's DM use *their* token, so the bot
+uploads as them and the message lands in their space.
+
+To revoke later: `/setup-files revoke` deletes only that user's token. Other
+users' tokens are untouched.
+
+### Scope
+
+The flow requests exactly one scope: `chat.messages.create`. That covers both
+`media.upload` and the `messages.create` that references the uploaded
+`attachmentDataRef`. No Drive, no broader Chat scopes — this is least-privilege
+on purpose.
+
+### Multi-user behavior
+
+When the asker has no per-user token yet, the bot falls back to a legacy
+single-user token at `~/.hermes/google_chat_user_token.json` (if present from
+a pre-multi-user install). When neither is available, the bot posts a clear
+text notice telling the asker to run `/setup-files`.
+
+A user revoking only clears their own slot. A 401/403 from one user's token
+evicts only that user's cache. Users don't disrupt each other.
+
+---
+
+## Troubleshooting
+
+**Bot stays silent after sending "hola."**
+
+1. Check the Pub/Sub subscription has undelivered messages in the console.
+   If it does, Hermes isn't authenticated — verify `GOOGLE_CHAT_SERVICE_ACCOUNT_JSON`
+   and that the SA is listed as `Pub/Sub Subscriber` on the subscription.
+2. If the subscription has zero messages, Google Chat isn't publishing.
+   Double-check the IAM binding on the **topic**:
+   `chat-api-push@system.gserviceaccount.com` must have `Pub/Sub Publisher`.
+3. Check `hermes gateway` logs for `[GoogleChat] Connected`. If you see
+   `[GoogleChat] Config validation failed`, the error message tells you which
+   env var to fix.
+
+**Bot replies but an error message appears instead of the agent's answer.**
+
+Check logs for `[GoogleChat] Pub/Sub stream died` — if these repeat, your SA
+credentials may have been rotated or the subscription deleted. After 10 attempts
+the adapter marks itself fatal.
+
+**"403 Forbidden" on every outbound message.**
+
+The bot was removed from the space, or you revoked it in the Chat API console.
+Re-install it in the space (the next `ADDED_TO_SPACE` event will re-enable
+messaging automatically).
+
+**Too many "Rate limit hit" warnings.**
+
+The Chat API's default quotas allow 60 messages per space per minute. If your
+agent produces long streaming responses that exceed that, the adapter retries
+with exponential backoff — but you'll still see user-visible latency. Consider
+concise responses or raising the quota in the GCP console.
+
+**Bot keeps posting the "/setup-files" notice instead of files.**
+
+The asker has no per-user OAuth token and there's no legacy fallback. Run
+`/setup-files` in their DM and follow Step 10. After the exchange completes
+the next file request uploads natively without a gateway restart.
+
+**`/setup-files start` says "No client credentials stored on the host."**
+
+The one-time host setup wasn't done. From a terminal on the host that runs
+Hermes:
+
+```bash
+python -m gateway.platforms.google_chat_user_oauth \
+    --client-secret /path/to/client_secret.json
+```
+
+Then send `/setup-files start` again.
+
+**`/setup-files <PASTED_URL>` says "Token exchange failed."**
+
+The auth code is single-use and short-lived (typically a few minutes). Send
+`/setup-files start` to get a fresh URL and retry.
+

+
+## Security notes
+
+- **Service Account scope**: the adapter requests `chat.bot` and `pubsub` scopes.
+  IAM should be the actual enforcement — grant your SA the minimum
+  (`roles/pubsub.subscriber` + `roles/pubsub.viewer` on the subscription), not
+  project-level or org-level Pub/Sub roles.
+- **Attachment download protection**: Hermes will only attach the SA bearer
+  token to URLs whose host matches a short allowlist of Google-owned domains
+  (`googleapis.com`, `drive.google.com`, `lh[3-6].googleusercontent.com`, and

+  `~/.hermes/google_chat_user_tokens/<sanitized_email>.json` (filesystem
+  permissions are the protection — same model as the SA key file). Each
+  token is owned by exactly one user; revoke is scoped to that user.

+:::important Runtime location
+The API server is a **Hermes agent runtime**, not a pure LLM proxy. For each request, Hermes creates a server-side `AIAgent` on the API-server host. Tool calls run where that API server is running.
+
+For example, if a laptop points Open WebUI or another OpenAI-compatible client at a Hermes API server on a remote machine, `pwd`, file tools, browser tools, local MCP tools, and other workspace tools run on the remote API-server host, not on the laptop.

 Open WebUI talks to Hermes server-to-server, so you do not need `API_SERVER_CORS_ORIGINS` for this integration.

+Your agent has access to the same tools and capabilities as that API-server Hermes instance. If the API server is remote, those tools are remote too.
+
+If you need tools to run against your **local** workspace today, run Hermes locally and point it at a pure LLM provider or pure OpenAI-compatible model proxy (for example vLLM, LiteLLM, Ollama, llama.cpp, OpenAI, OpenRouter, etc.). A future split-runtime mode for "remote brain, local hands" is being tracked in [#18715](https://github.com/NousResearch/hermes-agent/issues/18715); it is not the behavior of the current API server.
 
 :::tip Tool Progress
 With streaming enabled (the default), you'll see brief inline indicators as tools run — the tool emoji and its key argument. These appear in the response stream before the agent's final answer, giving you visibility into what's happening behind the scenes.

 Every route must have a secret — either set directly on the route or inherited from the global `secret`. Routes without a secret cause the adapter to fail at startup with an error. For development/testing only, you can set the secret to `"INSECURE_NO_AUTH"` to skip validation entirely.
 
+`INSECURE_NO_AUTH` is only accepted when the gateway is bound to a loopback host (`127.0.0.1`, `localhost`, `::1`). If it is combined with a non-loopback bind such as `0.0.0.0` or a LAN IP, the adapter refuses to start — this prevents accidentally exposing an unauthenticated endpoint on a public interface.

 ### Rate limiting
 
 Each route is rate-limited to **30 requests per minute** by default (fixed-window). Configure this globally:
