+"""Abstract base class for pluggable context engines.
+
+A context engine controls how conversation context is managed when
+approaching the model's token limit. The built-in ContextCompressor
+is the default implementation. Third-party engines (e.g. LCM) can
+replace it via the plugin system or by being placed in the
+``plugins/context_engine/<name>/`` directory.
+
+Selection is config-driven: ``context.engine`` in config.yaml.
+Default is ``"compressor"`` (the built-in). Only one engine is active.
+
+The engine is responsible for:
+  - Deciding when compaction should fire
+  - Performing compaction (summarization, DAG construction, etc.)
+  - Optionally exposing tools the agent can call (e.g. lcm_grep)
+  - Tracking token usage from API responses
+
+Lifecycle:
+  1. Engine is instantiated and registered (plugin register() or default)
+  2. on_session_start() called when a conversation begins
+  3. update_from_response() called after each API response with usage data
+  4. should_compress() checked after each turn
+  5. compress() called when should_compress() returns True
+  6. on_session_end() called at real session boundaries (CLI exit, /reset,
+     gateway session expiry) — NOT per-turn

+                Previously, progress markers like ``⏰ list`` were injected

+                (Open WebUI, LobeChat, …) store ``delta.content`` verbatim as

+                plain text instead of issuing real tool calls — silently
+                hallucinating tool results.  See #6972.
+
+                The fix: push a tagged tuple ``("__tool_progress__", payload)``
+                onto the stream queue.  The SSE writer emits it as a custom
+                ``event: hermes.tool.progress`` line that compliant frontends
+                can render for UX but will *not* persist into conversation
+                history.  Clients that don't understand the custom event type

+Session-scoped context variables for the Hermes gateway.
+
+Replaces the previous ``os.environ``-based session state
+(``HERMES_SESSION_PLATFORM``, ``HERMES_SESSION_CHAT_ID``, etc.) with
+Python's ``contextvars.ContextVar``.
+
+**Why this matters**
+
+The gateway processes messages concurrently via ``asyncio``.  When two
+messages arrive at the same time the old code did:
+
+    os.environ["HERMES_SESSION_THREAD_ID"] = str(context.source.thread_id)
+
+Because ``os.environ`` is *process-global*, Message A's value was
+silently overwritten by Message B before Message A's agent finished
+running.  Background-task notifications and tool calls therefore routed
+to the wrong thread.
+
+``contextvars.ContextVar`` values are *task-local*: each ``asyncio``
+task (and any ``run_in_executor`` thread it spawns) gets its own copy,
+so concurrent messages never interfere.
+
+**Backward compatibility**
+
+The public helper ``get_session_env(name, default="")`` mirrors the old
+``os.getenv("HERMES_SESSION_*", ...)`` calls.  Existing tool code only
+needs to replace the import + call site:
+
+    # before
+    import os
+    platform = os.getenv("HERMES_SESSION_PLATFORM", "")
+
+    # after

+- **Oblique Strategies** — when the user is maximally open ("surprise me," "something I've never seen")
+
+### Forced Connections
+1. Pick a domain unrelated to the visual goal (weather systems, microbiology, architecture, fluid dynamics, textile weaving)
+2. List its core visual/structural elements (erosion → gradual reveal; mitosis → splitting duplication; weaving → interlocking patterns)
+3. Map those elements onto ASCII characters and animation patterns
+4. Synthesize — what does "erosion" or "crystallization" look like in a character grid?
+
+### Conceptual Blending
+1. Name two distinct visual/conceptual spaces (e.g., ocean waves + sheet music)
+2. Map correspondences (crests = high notes, troughs = rests, foam = staccato)
+3. Blend selectively — keep the most interesting mappings, discard forced ones
+4. Develop emergent properties that exist only in the blend
+
+### Oblique Strategies
+1. Draw one: "Honor thy error as a hidden intention" / "Use an old idea" / "What would your closest friend do?" / "Emphasize the flaws" / "Turn it upside down" / "Only a part, not the whole" / "Reverse"
+2. Interpret the directive against the current ASCII animation challenge
+3. Apply the lateral insight to the visual design before writing code

+title: Creative Ideation — Constraint-Driven Project Generation
+description: "Generate project ideas through creative constraints. Use when the user says 'I want to build something', 'give me a project idea', 'I'm bored', 'what should I make', 'inspire me', or any variant of 'I have tools but no direction'. Works for code, art, hardware, writing, tools, and anything that can be made."

+
+# Creative Ideation
+
+Generate project ideas through creative constraints. Constraint + direction = creativity.
+
+## How It Works
+
+1. **Pick a constraint** from the library below — random, or matched to the user's domain/mood
+2. **Interpret it broadly** — a coding prompt can become a hardware project, an art prompt can become a CLI tool
+3. **Generate 3 concrete project ideas** that satisfy the constraint
+4. **If they pick one, build it** — create the project, write the code, ship it
+
+## The Rule
+
+Every prompt is interpreted as broadly as possible. "Does this include X?" → Yes. The prompts provide direction and mild constraint. Without either, there is no creativity.
+
+## Constraint Library
+
+### For Developers
+
+**Solve your own itch:**
+Build the tool you wished existed this week. Under 50 lines. Ship it today.
+
+**Automate the annoying thing:**
+What's the most tedious part of your workflow? Script it away. Two hours to fix a problem that costs you five minutes a day.
+
+**The CLI tool that should exist:**
+Think of a command you've wished you could type. `git undo-that-thing-i-just-did`. `docker why-is-this-broken`. `npm explain-yourself`. Now build it.
+
+**Nothing new except glue:**
+Make something entirely from existing APIs, libraries, and datasets. The only original contribution is how you connect them.
+
+**Frankenstein week:**
+Take something that does X and make it do Y. A git repo that plays music. A Dockerfile that generates poetry. A cron job that sends compliments.
+
+**Subtract:**
+How much can you remove from a codebase before it breaks? Strip a tool to its minimum viable function. Delete until only the essence remains.
+
+**High concept, low effort:**
+A deep idea, lazily executed. The concept should be brilliant. The implementation should take an afternoon. If it takes longer, you're overthinking it.
+
+### For Makers & Artists
+
+**Blatantly copy something:**
+Pick something you admire — a tool, an artwork, an interface. Recreate it from scratch. The learning is in the gap between your version and theirs.
+
+**One million of something:**
+One million is both a lot and not that much. One million pixels is a 1MB photo. One million API calls is a Tuesday. One million of anything becomes interesting at scale.
+
+**Make something that dies:**
+A website that loses a feature every day. A chatbot that forgets. A countdown to nothing. An exercise in rot, killing, or letting go.
+
+**Do a lot of math:**
+Generative geometry, shader golf, mathematical art, computational origami. Time to re-learn what an arcsin is.
+
+### For Anyone
+
+**Text is the universal interface:**
+Build something where text is the only interface. No buttons, no graphics, just words in and words out. Text can go in and out of almost anything.
+
+**Start at the punchline:**
+Think of something that would be a funny sentence. Work backwards to make it real. "I taught my thermostat to gaslight me" → now build it.
+
+**Hostile UI:**
+Make something intentionally painful to use. A password field that requires 47 conditions. A form where every label lies. A CLI that judges your commands.
+
+**Take two:**
+Remember an old project. Do it again from scratch. No looking at the original. See what changed about how you think.
+
+See `references/full-prompt-library.md` for 30+ additional constraints across communication, scale, philosophy, transformation, and more.
+
+## Matching Constraints to Users
+
+| User says | Pick from |
+|-----------|-----------|
+| "I want to build something" (no direction) | Random — any constraint |
+| "I'm learning [language]" | Blatantly copy something, Automate the annoying thing |
+| "I want something weird" | Hostile UI, Frankenstein week, Start at the punchline |
+| "I want something useful" | Solve your own itch, The CLI that should exist, Automate the annoying thing |
+| "I want something beautiful" | Do a lot of math, One million of something |
+| "I'm burned out" | High concept low effort, Make something that dies |
+| "Weekend project" | Nothing new except glue, Start at the punchline |
+| "I want a challenge" | One million of something, Subtract, Take two |
+
+## Output Format
+
+```
+## Constraint: [Name]
+> [The constraint, one sentence]
+
+### Ideas
+
+1. **[One-line pitch]**
+   [2-3 sentences: what you'd build and why it's interesting]
+   ⏱ [weekend / week / month] • 🔧 [stack]
+
+2. **[One-line pitch]**
+   [2-3 sentences]
+   ⏱ ... • 🔧 ...
+
+3. **[One-line pitch]**
+   [2-3 sentences]
+   ⏱ ... • 🔧 ...
+```
+
+## Example
+
+```
+## Constraint: The CLI tool that should exist
+> Think of a command you've wished you could type. Now build it.
+
+### Ideas
+
+1. **`git whatsup` — show what happened while you were away**
+   Compares your last active commit to HEAD and summarizes what changed,
+   who committed, and what PRs merged. Like a morning standup from your repo.
+   ⏱ weekend • 🔧 Python, GitPython, click
+
+2. **`explain 503` — HTTP status codes for humans**
+   Pipe any status code or error message and get a plain-English explanation
+   with common causes and fixes. Pulls from a curated database, not an LLM.
+   ⏱ weekend • 🔧 Rust or Go, static dataset
+
+3. **`deps why <package>` — why is this in my dependency tree**
+   Traces a transitive dependency back to the direct dependency that pulled
+   it in. Answers "why do I have 47 copies of lodash" in one command.
+   ⏱ weekend • 🔧 Node.js, npm/yarn lockfile parsing
+```
+
+After the user picks one, start building — create the project, write the code, iterate.

+# Full Prompt Library
+
+Extended constraint library beyond the core set in SKILL.md. Load these when the user wants more variety or a specific category.
+
+## Communication & Connection
+
+**Create a means of distribution:**
+The project works when you can use what you made to give something to somebody else.
+
+**Make a way to communicate:**
+The project works when you can hold a conversation with someone else using what you created. Not chat — something weirder.
+
+**Write a love letter:**
+To a person, a programming language, a game, a place, a tool. On paper, in code, in music, in light. Mail it.
+
+**Mail chess / Asynchronous games:**
+Something turn-based played with no time limit. No requirement to be there at the same time. The game happens in the gaps.
+
+**Twitch plays X:**
+A group of people share control over something. Collective input, emergent behavior.
+
+## Screens & Interfaces
+
+**Something for your desktop:**
+You spend a lot of time there. Spruce it up. A custom clock, a pet that lives in your terminal, a wallpaper that changes based on your git activity.
+
+**One screen, two screen, old screen, new screen:**
+Take something you associate with one screen and put it on a very different one. DOOM on a smart fridge. A spreadsheet on a watch. A terminal in a painting.
+
+**Make a mirror:**
+Something that reflects the viewer back at themselves. A website that shows your browsing history. A CLI that prints your git sins.
+
+## Philosophy & Concept
+
+**Code as koan, koan as code:**
+What is the sound of one hand clapping? A program that answers a question it wasn't asked. A function that returns before it's called.
+
+**The useless tree:**
+Make something useless. Deliberately, completely, beautifully useless. No utility. No purpose. No point. That's the point.
+
+**Artificial stupidity:**
+Make fun of AI by showcasing its faults. Mistrain it. Lie to it. Build the opposite of what AI is supposed to be good at.
+
+**"I use technology in order to hate it properly":**
+Make something inspired by the tension between loving and hating your tools.
+
+**The more things change, the more they stay the same:**
+Reflect on time, difference, and similarity.
+
+## Transformation
+
+**Translate:**
+Take something meant for one audience and make it understandable by another. A research paper as a children's book. An API as a board game. A song as an architecture diagram.
+
+**I mean, I GUESS you could store something that way:**
+The project works when you can save and open something. Store data in DNS caches. Encode a novel in emoji. Write a file system on top of something that isn't a file system.
+
+**I mean, I GUESS those could be pixels:**
+The project works when you can display an image. Render anything visual in a medium that wasn't meant for rendering.
+
+## Identity & Reflection
+
+**Make a self-portrait:**
+Be yourself? Be fake? Be real? In code, in data, in sound, in a directory structure.
+
+**Make a pun:**
+The stupider the better. Physical, digital, linguistic, visual. The project IS the joke.
+
+**Doors, walls, borders, barriers, boundaries:**
+Things that intermediate two places: opening, closing, permeating, excluding, combining.
+
+## Scale & Repetition
+
+**Lists!:**
+Itemizations, taxonomies, exhaustive recountings, iterations. This one. A list of list of lists.
+
+**Did you mean *recursion*?**
+Did you mean recursion?
+
+**Animals:**
+Lions, and tigers, and bears. Crab logic gates. Fish plays the stock market.
+
+**Cats:**
+Where would the internet be without them.
+
+## Starting Points
+
+**An idea that comes from a book:**
+Read something. Make something inspired by it.
+
+**Go to a museum:**
+Project ensues.
+
+**NPC loot:**
+What do you drop when you die? What do you take on your journey? Build the item.
+
+**Mythological objects and entities:**
+Pandora's box, the ocarina of time, the palantir. Build the artifact.
+
+**69:**
+Nice. Make something with the joke being the number 69.
+
+**Office Space printer scene:**
+Capture the same energy. Channel the catharsis of destroying the thing that frustrates you.
+
+**Borges week:**
+Something inspired by the Argentine. The library of babel. The map that is the territory.
+
+**Lights!:**
+LED throwies, light installations, illuminated anything. Make something that glows.

+
+### SCAMPER Transformation
+Take a standard mathematical/technical visualization and transform it:
+- **Substitute**: replace the standard visual metaphor (number line → winding path, matrix → city grid)

+### Assumption Reversal
+1. List what's "standard" about how this topic is visualized (left-to-right, 2D, discrete steps, formal notation)
+2. Pick the most fundamental assumption
+3. Reverse it (right-to-left derivation, 3D embedding of a 2D concept, continuous morphing instead of steps, zero notation)
+4. Explore what the reversal reveals that the standard approach hides

+- **Conceptual Blending** — when the user names two things to combine or wants hybrid aesthetics
+- **SCAMPER** — when the user wants a twist on a known generative art pattern
+- **Distance Association** — when the user gives a single concept and wants exploration ("make something about time")
+
+### Conceptual Blending
+1. Name two distinct visual systems (e.g., particle physics + handwriting)
+2. Map correspondences (particles = ink drops, forces = pen pressure, fields = letterforms)
+3. Blend selectively — keep mappings that produce interesting emergent visuals
+4. Code the blend as a unified system, not two systems side-by-side
+
+### SCAMPER Transformation
+Take a known generative pattern (flow field, particle system, L-system, cellular automata) and systematically transform it:
+- **Substitute**: replace circles with text characters, lines with gradients
+- **Combine**: merge two patterns (flow field + voronoi)
+- **Adapt**: apply a 2D pattern to a 3D projection
+- **Modify**: exaggerate scale, warp the coordinate space
+- **Purpose**: use a physics sim for typography, a sorting algorithm for color
+- **Eliminate**: remove the grid, remove color, remove symmetry
+- **Reverse**: run the simulation backward, invert the parameter space
+
+### Distance Association
+1. Anchor on the user's concept (e.g., "loneliness")
+2. Generate associations at three distances:
+   - Close (obvious): empty room, single figure, silence
+   - Medium (interesting): one fish in a school swimming the wrong way, a phone with no notifications, the gap between subway cars
+   - Far (abstract): prime numbers, asymptotic curves, the color of 3am
+3. Develop the medium-distance associations — they're specific enough to visualize but unexpected enough to be interesting

-"""Tests for DM thread session seeding.
+"""Tests for DM thread session isolation.
 
-When a bot reply creates a thread in a DM (e.g. Slack), the user's reply
-in that thread gets a new session (keyed by thread_ts). The seeding logic
-copies the parent DM session's transcript into the new thread session so
-the bot retains context of the original conversation.
+DM thread sessions must start empty — no parent transcript seeding.
+Thread context is handled by platform adapters (e.g. Slack's
+_fetch_thread_context fetches actual thread replies via the API).
+Session-level seeding was removed because it copied the ENTIRE parent
+DM transcript, causing unrelated conversations to bleed across threads.
 
 Covers:
-- Basic seeding: parent transcript copied to new thread session
-- No seeding for group/channel chats
-- No seeding when parent session doesn't exist
-- No seeding on auto-reset sessions
-- No seeding on existing (non-new) thread sessions
-- Parent transcript is not mutated by seeding
-- Multiple threads from same parent each get independent copies
-- Cross-platform: works for any platform with DM threads (Slack, Telegram, Discord)
+- Thread sessions start empty (no parent seeding)
+- Group/channel thread sessions also start empty
+- Multiple threads from same parent are independent
+- Existing thread sessions are not mutated on re-access
+- Cross-platform: consistent behavior for Slack, Telegram, Discord

+## Pluggable Context Engine
+
+Context management is built on the `ContextEngine` ABC (`agent/context_engine.py`). The built-in `ContextCompressor` is the default implementation, but plugins can replace it with alternative engines (e.g., Lossless Context Management).
+
+```yaml
+context:
+  engine: "compressor"    # default — built-in lossy summarization
+  engine: "lcm"           # example — plugin providing lossless context
+```
+
+The engine is responsible for:
+- Deciding when compaction should fire (`should_compress()`)
+- Performing compaction (`compress()`)
+- Optionally exposing tools the agent can call (e.g., `lcm_grep`)
+- Tracking token usage from API responses
+
+Selection is config-driven via `context.engine` in `config.yaml`. The resolution order:
+1. Check `plugins/context_engine/<name>/` directory
+2. Check general plugin system (`register_context_engine()`)
+3. Fall back to built-in `ContextCompressor`
+
+Plugin engines are **never auto-activated** — the user must explicitly set `context.engine` to the plugin's name. The default `"compressor"` always uses the built-in.
+
+Configure via `hermes plugins` → Provider Plugins → Context Engine, or edit `config.yaml` directly.
+
+For building a context engine plugin, see [Context Engine Plugins](/docs/developer-guide/context-engine-plugin).
+
 ## Dual Compression System
 
 Hermes has two separate compression layers that operate independently:

+description: "How to build a context engine plugin that replaces the built-in ContextCompressor"
+---
+
+# Building a Context Engine Plugin
+
+Context engine plugins replace the built-in `ContextCompressor` with an alternative strategy for managing conversation context. For example, a Lossless Context Management (LCM) engine that builds a knowledge DAG instead of lossy summarization.
+
+## How it works
+
+The agent's context management is built on the `ContextEngine` ABC (`agent/context_engine.py`). The built-in `ContextCompressor` is the default implementation. Plugin engines must implement the same interface.
+
+Only **one** context engine can be active at a time. Selection is config-driven:
+
+```yaml
+# config.yaml
+context:
+  engine: "compressor"    # default built-in
+  engine: "lcm"           # activates a plugin engine named "lcm"
+```
+
+Plugin engines are **never auto-activated** — the user must explicitly set `context.engine` to the plugin's name.
+
+## Directory structure
+
+Each context engine lives in `plugins/context_engine/<name>/`:
+
+```
+plugins/context_engine/lcm/
+├── __init__.py      # exports the ContextEngine subclass
+├── plugin.yaml      # metadata (name, description, version)
+└── ...              # any other modules your engine needs
+```
+
+## The ContextEngine ABC
+
+Your engine must implement these **required** methods:
+
+```python
+from agent.context_engine import ContextEngine
+
+class LCMEngine(ContextEngine):
+
+    @property
+    def name(self) -> str:
+        """Short identifier, e.g. 'lcm'. Must match config.yaml value."""
+        return "lcm"
+
+    def update_from_response(self, usage: dict) -> None:
+        """Called after every LLM call with the usage dict.
+
+        Update self.last_prompt_tokens, self.last_completion_tokens,
+        self.last_total_tokens from the response.
+        """
+
+    def should_compress(self, prompt_tokens: int = None) -> bool:
+        """Return True if compaction should fire this turn."""
+
+    def compress(self, messages: list, current_tokens: int = None) -> list:
+        """Compact the message list and return a new (possibly shorter) list.
+
+        The returned list must be a valid OpenAI-format message sequence.
+        """
+```
+
+### Class attributes your engine must maintain
+
+The agent reads these directly for display and logging:
+
+```python
+last_prompt_tokens: int = 0
+last_completion_tokens: int = 0
+last_total_tokens: int = 0
+threshold_tokens: int = 0        # when compression triggers
+context_length: int = 0          # model's full context window
+compression_count: int = 0       # how many times compress() has run
+```
+
+### Optional methods
+
+These have sensible defaults in the ABC. Override as needed:
+
+| Method | Default | Override when |
+|--------|---------|--------------|
+| `on_session_start(session_id, **kwargs)` | No-op | You need to load persisted state (DAG, DB) |
+| `on_session_end(session_id, messages)` | No-op | You need to flush state, close connections |
+| `on_session_reset()` | Resets token counters | You have per-session state to clear |
+| `update_model(model, context_length, ...)` | Updates context_length + threshold | You need to recalculate budgets on model switch |
+| `get_tool_schemas()` | Returns `[]` | Your engine provides agent-callable tools (e.g., `lcm_grep`) |
+| `handle_tool_call(name, args, **kwargs)` | Returns error JSON | You implement tool handlers |
+| `should_compress_preflight(messages)` | Returns `False` | You can do a cheap pre-API-call estimate |
+| `get_status()` | Standard token/threshold dict | You have custom metrics to expose |
+
+## Engine tools
+
+Context engines can expose tools the agent calls directly. Return schemas from `get_tool_schemas()` and handle calls in `handle_tool_call()`:
+
+```python
+def get_tool_schemas(self):
+    return [{
+        "name": "lcm_grep",
+        "description": "Search the context knowledge graph",
+        "parameters": {
+            "type": "object",
+            "properties": {
+                "query": {"type": "string", "description": "Search query"}
+            },
+            "required": ["query"],
+        },
+    }]
+
+def handle_tool_call(self, name, args, **kwargs):
+    if name == "lcm_grep":
+        results = self._search_dag(args["query"])
+        return json.dumps({"results": results})
+    return json.dumps({"error": f"Unknown tool: {name}"})
+```
+
+Engine tools are injected into the agent's tool list at startup and dispatched automatically — no registry registration needed.
+
+## Registration
+
+### Via directory (recommended)
+
+Place your engine in `plugins/context_engine/<name>/`. The `__init__.py` must export a `ContextEngine` subclass. The discovery system finds and instantiates it automatically.
+
+### Via general plugin system
+
+A general plugin can also register a context engine:
+
+```python
+def register(ctx):
+    engine = LCMEngine(context_length=200000)
+    ctx.register_context_engine(engine)
+```
+
+Only one engine can be registered. A second plugin attempting to register is rejected with a warning.
+
+## Lifecycle
+
+```
+1. Engine instantiated (plugin load or directory discovery)
+2. on_session_start() — conversation begins
+3. update_from_response() — after each API call
+4. should_compress() — checked each turn
+5. compress() — called when should_compress() returns True
+6. on_session_end() — session boundary (CLI exit, /reset, gateway expiry)
+```
+
+`on_session_reset()` is called on `/new` or `/reset` to clear per-session state without a full shutdown.
+
+## Configuration
+
+Users select your engine via `hermes plugins` → Provider Plugins → Context Engine, or by editing `config.yaml`:
+
+```yaml
+context:
+  engine: "lcm"   # must match your engine's name property
+```
+
+The `compression` config block (`compression.threshold`, `compression.protect_last_n`, etc.) is specific to the built-in `ContextCompressor`. Your engine should define its own config format if needed, reading from `config.yaml` during initialization.
+
+## Testing
+
+```python
+from agent.context_engine import ContextEngine
+
+def test_engine_satisfies_abc():
+    engine = YourEngine(context_length=200000)
+    assert isinstance(engine, ContextEngine)
+    assert engine.name == "your-name"
+
+def test_compress_returns_valid_messages():
+    engine = YourEngine(context_length=200000)
+    msgs = [{"role": "user", "content": "hello"}]
+    result = engine.compress(msgs)
+    assert isinstance(result, list)
+    assert all("role" in m for m in result)
+```
+
+See `tests/agent/test_context_engine.py` for the full ABC contract test suite.

+# Cron Troubleshooting
+
+When a cron job isn't behaving as expected, work through these checks in order. Most issues fall into one of four categories: timing, delivery, permissions, or skill loading.

+
+## Jobs Not Firing
+
+### Check 1: Verify the job exists and is active
+
+```bash
+hermes cron list
+```
+
+Look for the job and confirm its state is `[active]` (not `[paused]` or `[completed]`). If it shows `[completed]`, the repeat count may be exhausted — edit the job to reset it.
+
+### Check 2: Confirm the schedule is correct
+
+A misformatted schedule silently defaults to one-shot or is rejected entirely. Test your expression:

+| `0 9 * * 1` | 9:00 AM every Monday |
+| `every 2h` | Every 2 hours from now |
+| `30m` | 30 minutes from now |
+| `2025-06-01T09:00:00` | June 1, 2025 at 9:00 AM UTC |
+
+If the job fires once and then disappears from the list, it's a one-shot schedule (`30m`, `1d`, or an ISO timestamp) — expected behavior.
+
+### Check 3: Is the gateway running?
+
+Cron jobs are fired by the gateway's background ticker thread, which ticks every 60 seconds. A regular CLI chat session does **not** automatically fire cron jobs.
+
+If you're expecting jobs to fire automatically, you need a running gateway (`hermes gateway` or `hermes serve`). For one-off debugging, you can manually trigger a tick with `hermes cron tick`.
+
+### Check 4: Check the system clock and timezone
+
+Jobs use the local timezone. If your machine's clock is wrong or in a different timezone than expected, jobs will fire at the wrong times. Verify:
+
+```bash
+date
+hermes cron list   # Compare next_run times with local time
+```
+
+---
+
+## Delivery Failures
+
+### Check 1: Verify the deliver target is correct
+
+Delivery targets are case-sensitive and require the correct platform to be configured. A misconfigured target silently drops the response.
+
+| Target | Requires |
+|--------|----------|
+| `telegram` | `TELEGRAM_BOT_TOKEN` in `~/.hermes/.env` |
+| `discord` | `DISCORD_BOT_TOKEN` in `~/.hermes/.env` |
+| `slack` | `SLACK_BOT_TOKEN` in `~/.hermes/.env` |
+| `whatsapp` | WhatsApp gateway configured |
+| `signal` | Signal gateway configured |
+| `matrix` | Matrix homeserver configured |
+| `email` | SMTP configured in `config.yaml` |
+| `sms` | SMS provider configured |
+| `local` | Write access to `~/.hermes/cron/output/` |
+| `origin` | Delivers to the chat where the job was created |
+
+Other supported platforms include `mattermost`, `homeassistant`, `dingtalk`, `feishu`, `wecom`, `weixin`, `bluebubbles`, and `webhook`. You can also target a specific chat with `platform:chat_id` syntax (e.g., `telegram:-1001234567890`).
+
+If delivery fails, the job still runs — it just won't send anywhere. Check `hermes cron list` for updated `last_error` field (if available).
+
+### Check 2: Check `[SILENT]` usage
+
+If your cron job produces no output or the agent responds with `[SILENT]`, delivery is suppressed. This is intentional for monitoring jobs — but make sure your prompt isn't accidentally suppressing everything.
+
+A prompt that says "respond with [SILENT] if nothing changed" will silently swallow non-empty responses too. Check your conditional logic.
+
+### Check 3: Platform token permissions
+
+Each messaging platform bot needs specific permissions to receive messages. If delivery silently fails:
+
+- **Telegram**: Bot must be an admin in the target group/channel
+- **Discord**: Bot must have permission to send in the target channel
+- **Slack**: Bot must be added to the workspace and have `chat:write` scope
+
+### Check 4: Response wrapping
+
+By default, cron responses are wrapped with a header and footer (`cron.wrap_response: true` in `config.yaml`). Some platforms or integrations may not handle this well. To disable:
+
+```yaml
+cron:
+  wrap_response: false
+```
+
+---
+
+## Skill Loading Failures
+
+### Check 1: Verify skills are installed
+
+```bash
+hermes skills list
+```
+
+Skills must be installed before they can be attached to cron jobs. If a skill is missing, install it first with `hermes skills install <skill-name>` or via `/skills` in the CLI.
+
+### Check 2: Check skill name vs. skill folder name
+
+Skill names are case-sensitive and must match the installed skill's folder name. If your job specifies `ai-funding-daily-report` but the skill folder is `ai-funding-daily-report`, confirm the exact name from `hermes skills list`.
+
+### Check 3: Skills that require interactive tools
+
+Cron jobs run with the `cronjob`, `messaging`, and `clarify` toolsets disabled. This prevents recursive cron creation, direct message sending (delivery is handled by the scheduler), and interactive prompts. If a skill relies on these toolsets, it won't work in a cron context.
+
+Check the skill's documentation to confirm it works in non-interactive (headless) mode.
+
+### Check 4: Multi-skill ordering
+
+When using multiple skills, they load in order. If Skill A depends on context from Skill B, make sure B loads first:
+
+```bash
+/cron add "0 9 * * *" "..." --skill context-skill --skill target-skill
+```
+
+In this example, `context-skill` loads before `target-skill`.
+
+---
+
+## Job Errors and Failures
+
+### Check 1: Review recent job output
+
+If a job ran and failed, you may see error context in:
+
+1. The chat where the job delivers (if delivery succeeded)
+2. `~/.hermes/logs/agent.log` for scheduler messages (or `errors.log` for warnings)
+3. The job's `last_run` metadata via `hermes cron list`
+
+### Check 2: Common error patterns
+
+**"No such file or directory" for scripts**
+The `script` path must be an absolute path (or relative to the Hermes config directory). Verify:
+```bash
+ls ~/.hermes/scripts/your-script.py   # Must exist
+hermes cron edit <job_id> --script ~/.hermes/scripts/your-script.py
+```
+
+**"Skill not found" at job execution**
+The skill must be installed on the machine running the scheduler. If you move between machines, skills don't automatically sync — reinstall them with `hermes skills install <skill-name>`.
+
+**Job runs but delivers nothing**
+Likely a delivery target issue (see Delivery Failures above) or a silently suppressed response (`[SILENT]`).
+
+**Job hangs or times out**
+The scheduler uses an inactivity-based timeout (default 600s, configurable via `HERMES_CRON_TIMEOUT` env var, `0` for unlimited). The agent can run as long as it's actively calling tools — the timer only fires after sustained inactivity. Long-running jobs should use scripts to handle data collection and deliver only the result.
+
+### Check 3: Lock contention
+
+The scheduler uses file-based locking to prevent overlapping ticks. If two gateway instances are running (or a CLI session conflicts with a gateway), jobs may be delayed or skipped.
+
+Kill duplicate gateway processes:
+```bash
+ps aux | grep hermes
+# Kill duplicate processes, keep only one
+```
+
+### Check 4: Permissions on jobs.json
+
+Jobs are stored in `~/.hermes/cron/jobs.json`. If this file is not readable/writable by your user, the scheduler will fail silently:
+
+```bash
+ls -la ~/.hermes/cron/jobs.json
+chmod 600 ~/.hermes/cron/jobs.json   # Your user should own it
+```
+
+---
+
+## Performance Issues
+
+### Slow job startup
+
+Each cron job creates a fresh AIAgent session, which may involve provider authentication and model loading. For time-sensitive schedules, add buffer time (e.g., `0 8 * * *` instead of `0 9 * * *`).
+
+### Too many overlapping jobs
+
+The scheduler executes jobs sequentially within each tick. If multiple jobs are due at the same time, they run one after another. Consider staggering schedules (e.g., `0 9 * * *` and `5 9 * * *` instead of both at `0 9 * * *`) to avoid delays.
+
+### Large script output
+
+Scripts that dump megabytes of output will slow down the agent and may hit token limits. Filter/summarize at the script level — emit only what the agent needs to reason about.
+
+---
+
+## Diagnostic Commands
+
+```bash
+hermes cron list                    # Show all jobs, states, next_run times
+hermes cron run <job_id>            # Schedule for next tick (for testing)
+hermes cron edit <job_id>           # Fix configuration issues
+hermes logs                         # View recent Hermes logs
+hermes skills list                  # Verify installed skills
+```
+
+---
+
+## Getting More Help
+
+If you've worked through this guide and the issue persists:
+
+1. Run the job with `hermes cron run <job_id>` (fires on next gateway tick) and watch for errors in the chat output
+2. Check `~/.hermes/logs/agent.log` for scheduler messages and `~/.hermes/logs/errors.log` for warnings
+3. Open an issue at [github.com/NousResearch/hermes-agent](https://github.com/NousResearch/hermes-agent) with:
+   - The job ID and schedule
+   - The delivery target
+   - What you expected vs. what happened
+   - Relevant error messages from the logs

+
+## Timeouts
+
+Hermes automatically detects local endpoints (localhost, LAN IPs) and relaxes its streaming timeouts. No configuration needed for most setups.
+
+If you still hit timeout errors (e.g. very large contexts on slow hardware), you can override the streaming read timeout:
+
+```bash
+# In your .env — raise from the 120s default to 30 minutes
+HERMES_STREAM_READ_TIMEOUT=1800
+```
+
+| Timeout | Default | Local auto-adjustment | Env var override |
+|---------|---------|----------------------|------------------|
+| Stream read (socket-level) | 120s | Raised to 1800s | `HERMES_STREAM_READ_TIMEOUT` |
+| Stale stream detection | 180s | Disabled entirely | `HERMES_STREAM_STALE_TIMEOUT` |
+| API call (non-streaming) | 1800s | No change needed | `HERMES_API_TIMEOUT` |
+
+The stream read timeout is the one most likely to cause issues — it's the socket-level deadline for receiving the next chunk of data. During prefill on large contexts, local models may produce no output for minutes while processing the prompt. The auto-detection handles this transparently.

+#### WSL: Gateway keeps disconnecting or `hermes gateway start` fails
+
+**Cause:** WSL's systemd support is unreliable. Many WSL2 installations don't have systemd enabled, and even when enabled, services may not survive WSL restarts or Windows idle shutdowns.
+
+**Solution:** Use foreground mode instead of the systemd service:
+
+```bash
+# Option 1: Direct foreground (simplest)
+hermes gateway run
+
+# Option 2: Persistent via tmux (survives terminal close)
+tmux new -s hermes 'hermes gateway run'
+# Reattach later: tmux attach -t hermes
+
+# Option 3: Background via nohup
+nohup hermes gateway run > ~/.hermes/logs/gateway.log 2>&1 &
+```
+
+If you want to try systemd anyway, make sure it's enabled:
+
+1. Open `/etc/wsl.conf` (create it if it doesn't exist)
+2. Add:
+   ```ini
+   [boot]
+   systemd=true
+   ```
+3. From PowerShell: `wsl --shutdown`
+4. Reopen your WSL terminal
+5. Verify: `systemctl is-system-running` should say "running" or "degraded"

 **Cause:** launchd services inherit a minimal PATH (`/usr/bin:/bin:/usr/sbin:/sbin`) that doesn't include Homebrew, nvm, cargo, or other user-installed tool directories. This commonly breaks the WhatsApp bridge (`node not found`) or voice transcription (`ffmpeg not found`).

+## Context Engine
+
+The context engine controls how conversations are managed when approaching the model's token limit. The built-in `compressor` engine uses lossy summarization (see [Context Compression](/docs/developer-guide/context-compression-and-caching)). Plugin engines can replace it with alternative strategies.

 Budget pressure is enabled by default. The agent sees warnings naturally as part of tool results, encouraging it to consolidate its work and deliver a response before running out of iterations.
 
+### Streaming Timeouts
+
+The LLM streaming connection has two timeout layers. Both auto-adjust for local providers (localhost, LAN IPs) — no configuration needed for most setups.
+
+| Timeout | Default | Local providers | Env var |
+|---------|---------|----------------|---------|
+| Socket read timeout | 120s | Auto-raised to 1800s | `HERMES_STREAM_READ_TIMEOUT` |
+| Stale stream detection | 180s | Auto-disabled | `HERMES_STREAM_STALE_TIMEOUT` |
+| API call (non-streaming) | 1800s | Unchanged | `HERMES_API_TIMEOUT` |
+
+The **socket read timeout** controls how long httpx waits for the next chunk of data from the provider. Local LLMs can take minutes for prefill on large contexts before producing the first token, so Hermes raises this to 30 minutes when it detects a local endpoint. If you explicitly set `HERMES_STREAM_READ_TIMEOUT`, that value is always used regardless of endpoint detection.
+
+The **stale stream detection** kills connections that receive SSE keep-alive pings but no actual content. This is disabled entirely for local providers since they don't send keep-alive pings during prefill.
+
 ## Context Pressure Warnings
 
 Separate from iteration budget pressure, context pressure tracks how close the conversation is to the **compaction threshold** — the point where context compression fires to summarize older messages. This helps both you and the agent understand when the conversation is getting long.

+Pre-run scripts (attached via the `script` parameter) have a default timeout of 120 seconds. If your scripts need longer — for example, to include randomized delays that avoid bot-like timing patterns — you can increase this:
+
+```yaml
+# ~/.hermes/config.yaml
+cron:
+  script_timeout_seconds: 300   # 5 minutes
+```
+
+Or set the `HERMES_CRON_SCRIPT_TIMEOUT` environment variable. The resolution order is: env var → config.yaml → 120s default.
+
+## Provider recovery
+
+Cron jobs inherit your configured fallback providers and credential pool rotation. If the primary API key is rate-limited or the provider returns an error, the cron agent can:
+
+- **Fall back to an alternate provider** if you have `fallback_providers` (or the legacy `fallback_model`) configured in `config.yaml`
+- **Rotate to the next credential** in your [credential pool](/docs/user-guide/configuration#credential-pool-strategies) for the same provider
+
+This means cron jobs that run at high frequency or during peak hours are more resilient — a single rate-limited key won't fail the entire run.
+
 ## Schedule formats
 
 The agent's final response is automatically delivered — you do **not** need to include `send_message` in the cron prompt for that same destination. If a cron run calls `send_message` to the exact target the scheduler will already deliver to, Hermes skips that duplicate send and tells the model to put the user-facing content in the final response instead. Use `send_message` only for additional or different targets.

+---
+
+# Weixin (WeChat)
+
+Connect Hermes to [WeChat](https://weixin.qq.com/) (微信), Tencent's personal messaging platform. The adapter uses Tencent's **iLink Bot API** for personal WeChat accounts — this is distinct from WeCom (Enterprise WeChat). Messages are delivered via long-polling, so no public endpoint or webhook is required.
+
+:::info
+This adapter is for **personal WeChat accounts** (微信). If you need enterprise/corporate WeChat, see the [WeCom adapter](./wecom.md) instead.
+:::
+
+## Prerequisites
+
+- A personal WeChat account
+- Python packages: `aiohttp` and `cryptography`
+- The `qrcode` package is optional (for terminal QR rendering during setup)
+
+Install the required dependencies:
+
+```bash
+pip install aiohttp cryptography
+# Optional: for terminal QR code display
+pip install qrcode
+```
+
+## Setup
+
+### 1. Run the Setup Wizard
+
+The easiest way to connect your WeChat account is through the interactive setup:
+
+```bash
+hermes gateway setup
+```
+
+Select **Weixin** when prompted. The wizard will:
+
+1. Request a QR code from the iLink Bot API
+2. Display the QR code in your terminal (or provide a URL)
+3. Wait for you to scan the QR code with the WeChat mobile app
+4. Prompt you to confirm the login on your phone
+5. Save the account credentials automatically to `~/.hermes/weixin/accounts/`
+
+Once confirmed, you'll see a message like:
+
+```
+微信连接成功，account_id=your-account-id
+```
+
+The wizard stores the `account_id`, `token`, and `base_url` so you don't need to configure them manually.
+
+### 2. Configure Environment Variables
+
+After initial QR login, set at minimum the account ID in `~/.hermes/.env`:
+
+```bash
+WEIXIN_ACCOUNT_ID=your-account-id
+
+# Optional: override the token (normally auto-saved from QR login)
+# WEIXIN_TOKEN=your-bot-token
+
+# Optional: restrict access
+WEIXIN_DM_POLICY=open
+WEIXIN_ALLOWED_USERS=user_id_1,user_id_2
+
+# Optional: home channel for cron/notifications
+WEIXIN_HOME_CHANNEL=chat_id
+WEIXIN_HOME_CHANNEL_NAME=Home
+```
+
+### 3. Start the Gateway
+
+```bash
+hermes gateway
+```
+
+The adapter will restore saved credentials, connect to the iLink API, and begin long-polling for messages.
+
+## Features
+
+- **Long-poll transport** — no public endpoint, webhook, or WebSocket needed
+- **QR code login** — scan-to-connect setup via `hermes gateway setup`
+- **DM and group messaging** — configurable access policies
+- **Media support** — images, video, files, and voice messages
+- **AES-128-ECB encrypted CDN** — automatic encryption/decryption for all media transfers
+- **Context token persistence** — disk-backed reply continuity across restarts
+- **Markdown formatting** — headers, tables, and code blocks are reformatted for WeChat readability
+- **Smart message chunking** — long messages are split at logical boundaries (paragraphs, code fences)
+- **Typing indicators** — shows "typing…" status in the WeChat client while the agent processes
+- **SSRF protection** — outbound media URLs are validated before download
+- **Message deduplication** — 5-minute sliding window prevents double-processing
+- **Automatic retry with backoff** — recovers from transient API errors
+
+## Configuration Options
+
+Set these in `config.yaml` under `platforms.weixin.extra`:
+
+| Key | Default | Description |
+|-----|---------|-------------|
+| `account_id` | — | iLink Bot account ID (required) |
+| `token` | — | iLink Bot token (required, auto-saved from QR login) |
+| `base_url` | `https://ilinkai.weixin.qq.com` | iLink API base URL |
+| `cdn_base_url` | `https://novac2c.cdn.weixin.qq.com/c2c` | CDN base URL for media transfer |
+| `dm_policy` | `open` | DM access: `open`, `allowlist`, `disabled`, `pairing` |
+| `group_policy` | `disabled` | Group access: `open`, `allowlist`, `disabled` |
+| `allow_from` | `[]` | User IDs allowed for DMs (when dm_policy=allowlist) |
+| `group_allow_from` | `[]` | Group IDs allowed (when group_policy=allowlist) |
+
+## Access Policies
+
+### DM Policy
+
+Controls who can send direct messages to the bot:
+
+| Value | Behavior |
+|-------|----------|
+| `open` | Anyone can DM the bot (default) |
+| `allowlist` | Only user IDs in `allow_from` can DM |
+| `disabled` | All DMs are ignored |
+| `pairing` | Pairing mode (for initial setup) |
+
+```bash
+WEIXIN_DM_POLICY=allowlist
+WEIXIN_ALLOWED_USERS=user_id_1,user_id_2
+```
+
+### Group Policy
+
+Controls which groups the bot responds in:
+
+| Value | Behavior |
+|-------|----------|
+| `open` | Bot responds in all groups |
+| `allowlist` | Bot only responds in group IDs listed in `group_allow_from` |
+| `disabled` | All group messages are ignored (default) |
+
+```bash
+WEIXIN_GROUP_POLICY=allowlist
+WEIXIN_GROUP_ALLOWED_USERS=group_id_1,group_id_2
+```
+
+:::note
+The default group policy is `disabled` for Weixin (unlike WeCom where it defaults to `open`). This is intentional since personal WeChat accounts may be in many groups.
+:::
+
+## Media Support
+
+### Inbound (receiving)
+
+The adapter receives media attachments from users, downloads them from the WeChat CDN, decrypts them, and caches them locally for agent processing:
+
+| Type | How it's handled |
+|------|-----------------| 
+| **Images** | Downloaded, AES-decrypted, and cached as JPEG. |
+| **Video** | Downloaded, AES-decrypted, and cached as MP4. |
+| **Files** | Downloaded, AES-decrypted, and cached. Original filename is preserved. |
+| **Voice** | If a text transcription is available, it's extracted as text. Otherwise the audio (SILK format) is downloaded and cached. |
+
+**Quoted messages:** Media from quoted (replied-to) messages is also extracted, so the agent has context about what the user is replying to.
+
+### AES-128-ECB Encrypted CDN
+
+WeChat media files are transferred through an encrypted CDN. The adapter handles this transparently:
+
+- **Inbound:** Encrypted media is downloaded from the CDN using `encrypted_query_param` URLs, then decrypted with AES-128-ECB using the per-file key provided in the message payload.
+- **Outbound:** Files are encrypted locally with a random AES-128-ECB key, uploaded to the CDN, and the encrypted reference is included in the outbound message.
+- The AES key is 16 bytes (128-bit). Keys may arrive as raw base64 or hex-encoded — the adapter handles both formats.
+- This requires the `cryptography` Python package.
+
+No configuration is needed — encryption and decryption happen automatically.
+
+### Outbound (sending)
+
+| Method | What it sends |
+|--------|--------------|
+| `send` | Text messages with Markdown formatting | 
+| `send_image` / `send_image_file` | Native image messages (via CDN upload) |
+| `send_document` | File attachments (via CDN upload) |
+| `send_video` | Video messages (via CDN upload) |
+
+All outbound media goes through the encrypted CDN upload flow:
+
+1. Generate a random AES-128 key
+2. Encrypt the file with AES-128-ECB + PKCS#7 padding
+3. Request an upload URL from the iLink API (`getuploadurl`)
+4. Upload the ciphertext to the CDN
+5. Send the message with the encrypted media reference
+
+## Context Token Persistence
+
+The iLink Bot API requires a `context_token` to be echoed back with each outbound message for a given peer. The adapter maintains a disk-backed context token store:
+
+- Tokens are saved per account+peer to `~/.hermes/weixin/accounts/<account_id>.context-tokens.json`
+- On startup, previously saved tokens are restored
+- Every inbound message updates the stored token for that sender
+- Outbound messages automatically include the latest context token
+
+This ensures reply continuity even after gateway restarts.
+
+## Markdown Formatting
+
+WeChat's personal chat does not natively render full Markdown. The adapter reformats content for better readability:
+
+- **Headers** (`# Title`) → converted to `【Title】` (level 1) or `**Title**` (level 2+)
+- **Tables** → reformatted as labeled key-value lists (e.g., `- Column: Value`)
+- **Code fences** → preserved as-is (WeChat renders these adequately)
+- **Excessive blank lines** → collapsed to double newlines
+
+## Message Chunking
+
+Long messages are split intelligently for chat delivery:
+
+- Maximum message length: **4000 characters**
+- Split points prefer paragraph boundaries and blank lines
+- Code fences are kept intact (never split mid-block)
+- Indented continuation lines (sub-items in reformatted tables/lists) stay with their parent
+- Oversized individual blocks fall back to the base adapter's truncation logic
+
+## Typing Indicators
+
+The adapter shows typing status in the WeChat client:
+
+1. When a message arrives, the adapter fetches a `typing_ticket` via the `getconfig` API
+2. Typing tickets are cached for 10 minutes per user
+3. `send_typing` sends a typing-start signal; `stop_typing` sends a typing-stop signal
+4. The gateway automatically triggers typing indicators while the agent processes a message
+
+## Long-Poll Connection
+
+The adapter uses HTTP long-polling (not WebSocket) to receive messages:
+
+### How It Works
+
+1. **Connect:** Validates credentials and starts the poll loop
+2. **Poll:** Calls `getupdates` with a 35-second timeout; the server holds the request until messages arrive or the timeout expires
+3. **Dispatch:** Inbound messages are dispatched concurrently via `asyncio.create_task`
+4. **Sync buffer:** A persistent sync cursor (`get_updates_buf`) is saved to disk so the adapter resumes from the correct position after restarts
+
+### Retry Behavior
+
+On API errors, the adapter uses a simple retry strategy:
+
+| Condition | Behavior |
+|-----------|----------|
+| Transient error (1st–2nd) | Retry after 2 seconds |
+| Repeated errors (3+) | Back off for 30 seconds, then reset counter |
+| Session expired (`errcode=-14`) | Pause for 10 minutes (re-login may be needed) |
+| Timeout | Immediately re-poll (normal long-poll behavior) |
+
+### Deduplication
+
+Inbound messages are deduplicated using message IDs with a 5-minute window. This prevents double-processing during network hiccups or overlapping poll responses.
+
+### Token Lock
+
+Only one Weixin gateway instance can use a given token at a time. The adapter acquires a scoped lock on startup and releases it on shutdown. If another gateway is already using the same token, startup fails with an informative error message.
+
+## All Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| `WEIXIN_ACCOUNT_ID` | ✅ | — | iLink Bot account ID (from QR login) |
+| `WEIXIN_TOKEN` | ✅ | — | iLink Bot token (auto-saved from QR login) |
+| `WEIXIN_BASE_URL` | — | `https://ilinkai.weixin.qq.com` | iLink API base URL |
+| `WEIXIN_CDN_BASE_URL` | — | `https://novac2c.cdn.weixin.qq.com/c2c` | CDN base URL for media transfer |
+| `WEIXIN_DM_POLICY` | — | `open` | DM access policy: `open`, `allowlist`, `disabled`, `pairing` |
+| `WEIXIN_GROUP_POLICY` | — | `disabled` | Group access policy: `open`, `allowlist`, `disabled` |
+| `WEIXIN_ALLOWED_USERS` | — | _(empty)_ | Comma-separated user IDs for DM allowlist |
+| `WEIXIN_GROUP_ALLOWED_USERS` | — | _(empty)_ | Comma-separated group IDs for group allowlist |
+| `WEIXIN_HOME_CHANNEL` | — | — | Chat ID for cron/notification output |
+| `WEIXIN_HOME_CHANNEL_NAME` | — | `Home` | Display name for the home channel |
+| `WEIXIN_ALLOW_ALL_USERS` | — | — | Gateway-level flag to allow all users (used by setup wizard) |
+
+## Troubleshooting
+
+| Problem | Fix |
+|---------|-----|
+| `Weixin startup failed: aiohttp and cryptography are required` | Install both: `pip install aiohttp cryptography` |
+| `Weixin startup failed: WEIXIN_TOKEN is required` | Run `hermes gateway setup` to complete QR login, or set `WEIXIN_TOKEN` manually |
+| `Weixin startup failed: WEIXIN_ACCOUNT_ID is required` | Set `WEIXIN_ACCOUNT_ID` in your `.env` or run `hermes gateway setup` |
+| `Another local Hermes gateway is already using this Weixin token` | Stop the other gateway instance first — only one poller per token is allowed |
+| Session expired (`errcode=-14`) | Your login session has expired. Re-run `hermes gateway setup` to scan a new QR code |
+| QR code expired during setup | The QR auto-refreshes up to 3 times. If it keeps expiring, check your network connection |
+| Bot doesn't respond to DMs | Check `WEIXIN_DM_POLICY` — if set to `allowlist`, the sender must be in `WEIXIN_ALLOWED_USERS` |
+| Bot ignores group messages | Group policy defaults to `disabled`. Set `WEIXIN_GROUP_POLICY=open` or `allowlist` |
+| Media download/upload fails | Ensure `cryptography` is installed. Check network access to `novac2c.cdn.weixin.qq.com` |
+| `Blocked unsafe URL (SSRF protection)` | The outbound media URL points to a private/internal address. Only public URLs are allowed |
+| Voice messages show as text | If WeChat provides a transcription, the adapter uses the text. This is expected behavior |
+| Messages appear duplicated | The adapter deduplicates by message ID. If you see duplicates, check if multiple gateway instances are running |
+| `iLink POST ... HTTP 4xx/5xx` | API error from the iLink service. Check your token validity and network connectivity |
+| Terminal QR code doesn't render | Install `qrcode`: `pip install qrcode`. Alternatively, open the URL printed above the QR |
