From 401aadb5b8926c1ce9cdc9a57b5700dacd835732 Mon Sep 17 00:00:00 2001 From: emozilla Date: Tue, 5 May 2026 12:46:51 -0400 Subject: [PATCH 001/148] docs(security): rewrite policy around OS-level isolation as the boundary MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Restate the trust model from first principles: the OS is the only load-bearing boundary against an adversarial LLM. Distinguish terminal-backend isolation (sandboxes the shell tool) from whole-process wrapping (sandboxes the agent itself, reference deployment NVIDIA OpenShell). Name in-process components (approval gate, output redaction, Skills Guard) as heuristics, and the class of reports that defeat them as out of scope under this policy — while explicitly welcoming them as regular issues or PRs. Introduce 'agent-loaded content' as the narrow, honest commitment: attacker-influenced input must not chain into a write the agent later loads on its own initiative. Strip implementation-detail enumerations (backend names, adapter names, config keys, env vars, internal symbols) so the doc stays evergreen as code evolves. --- SECURITY.md | 260 +++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 205 insertions(+), 55 deletions(-) diff --git a/SECURITY.md b/SECURITY.md index 3cede2885e6..ad9dc4149b3 100644 --- a/SECURITY.md +++ b/SECURITY.md @@ -1,84 +1,234 @@ # Hermes Agent Security Policy -This document outlines the security protocols, trust model, and deployment hardening guidelines for the **Hermes Agent** project. +This document describes Hermes Agent's trust model, names the one +security boundary the project treats as load-bearing, and defines the +scope for vulnerability reports. -## 1.

Trust Model -The core assumption is that Hermes is a **personal agent** with one trusted operator. +Hermes is a single-tenant personal agent. Its posture is layered, and +the layers are not equally load-bearing. Reporters and operators +should reason about them in the same terms. -### Operator & Session Trust -- **Single Tenant:** The system protects the operator from LLM actions, not from malicious co-tenants. Multi-user isolation must happen at the OS/host level. -- **Gateway Security:** Authorized callers (Telegram, Discord, Slack, etc.) receive equal trust. Session keys are used for routing, not as authorization boundaries. -- **Execution:** Defaults to `terminal.backend: local` (direct host execution). Container isolation (Docker, Modal, Daytona) is opt-in for sandboxing. +### 2.1 The Boundary: OS-Level Isolation -### Dangerous Command Approval -The approval system (`tools/approval.py`) is a core security boundary. Terminal commands, file operations, and other potentially destructive actions are gated behind explicit user confirmation before execution. The approval mode is configurable via `approvals.mode` in `config.yaml`: -- `"on"` (default) — prompts the user to approve dangerous commands. -- `"auto"` — auto-approves after a configurable delay. -- `"off"` — disables the gate entirely (break-glass; see Section 3). +**The only security boundary against an adversarial LLM is the +operating system.** Nothing inside the agent process constitutes +containment — not the approval gate, not output redaction, not any +pattern scanner, not any tool allowlist. Any in-process component +that screens LLM output is a heuristic operating on an +attacker-influenced string, and this policy treats it as such. -### Output Redaction -`agent/redact.py` strips secret-like patterns (API keys, tokens, credentials) from all display output before it reaches the terminal or gateway platform. This prevents accidental credential leakage in chat logs, tool previews, and response text. Redaction operates on the display layer only — underlying values remain intact for internal agent operations. +Hermes supports two OS-level isolation postures. They address +different threats and an operator should choose deliberately. -### Skills vs. MCP Servers -- **Installed Skills:** High trust. Equivalent to local host code; skills can read environment variables and run arbitrary commands. -- **MCP Servers:** Lower trust. MCP subprocesses receive a filtered environment (`_build_safe_env()` in `tools/mcp_tool.py`) — only safe baseline variables (`PATH`, `HOME`, `XDG_*`) plus variables explicitly declared in the server's `env` config block are passed through. Host credentials are stripped by default. Additionally, packages invoked via `npx`/`uvx` are checked against the OSV malware database before spawning. +**Terminal-backend isolation** sandboxes the shell tool. A +non-default terminal backend runs LLM-emitted shell commands inside +a container, remote host, or cloud sandbox. This confines the blast +radius of destructive shell — but only of shell. The Python process +running the agent itself stays on the host, along with every code +path that doesn't go through the shell tool: the code-execution +tool, MCP subprocesses, file tools, plugin loading, hook dispatch, +skill loading. This is the right posture when the concern is +LLM-emitted destructive shell and the operator is otherwise +trusted. -### Code Execution Sandbox -The `execute_code` tool (`tools/code_execution_tool.py`) runs LLM-generated Python scripts in a child process with API keys and tokens stripped from the environment to prevent credential exfiltration. Only environment variables explicitly declared by loaded skills (via `env_passthrough`) or by the user in `config.yaml` (`terminal.env_passthrough`) are passed through. The child accesses Hermes tools via RPC, not direct API calls. +**Whole-process wrapping** sandboxes the agent itself. The agent +runs inside an external runtime that enforces filesystem, network, +process, and inference policies across the entire agent process +tree. [NVIDIA OpenShell](https://github.com/NVIDIA/OpenShell) is +the reference deployment. Under this posture, every code path in +the agent is subject to the same policy, and the in-process +heuristics in §2.3 become accident-prevention layered on top of a +real boundary. This is the supported posture when the agent +ingests content from surfaces the operator does not control — the +open web, inbound email, multi-user channels, untrusted MCP +servers — and for production or shared deployments. -### Subagents -- **No recursive delegation:** The `delegate_task` tool is disabled for child agents. -- **Depth limit:** `MAX_DEPTH = 2` — parent (depth 0) can spawn a child (depth 1); grandchildren are rejected. -- **Memory isolation:** Subagents run with `skip_memory=True` and do not have access to the parent's persistent memory provider. The parent receives only the task prompt and final response as an observation. +Operators running the default local backend with untrusted input +surfaces, or running a terminal-backend sandbox and expecting it to +contain code paths that don't go through the shell, are operating +outside the supported security posture. + +### 2.2 Credential Scoping + +Hermes filters the environment it passes to its lower-trust +in-process components: shell subprocesses, MCP subprocesses, and +the code-execution child. Credentials like provider API keys and +gateway tokens are stripped by default; variables explicitly +declared by the operator or by a loaded skill are passed through. + +This reduces casual exfiltration. It is not containment. A +component with code-execution primitives can always reach +filesystem-resident credentials that the agent process itself can +read. + +### 2.3 In-Process Heuristics + +The following components screen or warn about LLM behavior. They +are useful. They are not boundaries. + +- The **approval gate** detects common destructive shell patterns + and prompts the operator before execution. Shell is Turing- + complete; a denylist over shell strings is structurally + incomplete. The gate catches cooperative-mode mistakes, not + adversarial output. +- **Output redaction** strips secret-like patterns from display. + A motivated output producer will defeat it. +- **Skills Guard** scans installable skill content for injection + patterns. It is a review aid; the boundary for third-party skills + is operator review before install. + +### 2.4 Gateway Authorization + +When the gateway integrates with a messaging platform, each platform +adapter authenticates callers against an operator-configured +allowlist. **An allowlist is required for every enabled adapter.** +Adapters should refuse to dispatch agent work, resolve approvals, or +relay output until an allowlist is set; code paths that fail open +when no allowlist is configured are code bugs in scope under §3.1. +Within the allowlist, all authorized callers are equally trusted. +Session identifiers are routing handles, not authorization +boundaries. + +### 2.5 Agent-Loaded Content + +Hermes chooses, by design, to load and execute content from specific +on-disk locations at its own initiative — skills, hooks, plugins, +operator-configured shortcuts. Content placed in these locations +becomes code the agent runs on its next session, hook dispatch, or +command invocation. + +Hermes does not claim these locations are protected files. +Filesystem-level protection is whatever the OS provides under the +operator's chosen isolation posture (§2.1). What Hermes commits to +is narrower and different: **attacker-influenced input must not be +chainable into a write that Hermes would later load and execute on +its own initiative**. The concern is not what the filesystem +allows; it is what Hermes loads. --- -## 3. Out of Scope (Non-Vulnerabilities) +## 3. Scope -The following scenarios are **not** considered security breaches: -- **Prompt Injection:** Unless it results in a concrete bypass of the approval system, toolset restrictions, or container sandbox. -- **Public Exposure:** Deploying the gateway to the public internet without external authentication or network protection. -- **Trusted State Access:** Reports that require pre-existing write access to `~/.hermes/`, `.env`, or `config.yaml` (these are operator-owned files). -- **Default Behavior:** Host-level command execution when `terminal.backend` is set to `local` — this is the documented default, not a vulnerability. -- **Configuration Trade-offs:** Intentional break-glass settings such as `approvals.mode: "off"` or `terminal.backend: local` in production. -- **Tool-level read/access restrictions:** The agent has unrestricted shell access via the `terminal` tool by design. Reports that a specific tool (e.g., `read_file`) can access a resource are not vulnerabilities if the same access is available through `terminal`. Tool-level deny lists only constitute a meaningful security boundary when paired with equivalent restrictions on the terminal side (as with write operations, where `WRITE_DENIED_PATHS` is paired with the dangerous command approval system). +### 3.1 In Scope + +- Escape from a declared OS-level isolation posture (§2.1): an + attacker-controlled code path reaching state that the posture + claimed to confine. +- Unauthorized gateway access: a caller outside the configured + allowlist dispatching work, receiving output, or resolving + approvals (§2.4). +- Credential exfiltration: leakage of operator credentials or + session authorization material to a destination outside the + operator's trust envelope. +- Untrusted input chaining into agent-loaded content: an untrusted + input surface chains into a write whose target is a location + Hermes loads and executes on its own initiative (§2.5). +- Output integrity failures into external platforms: agent output + rendered on a receiving platform with unintended authority — + broadcast-mention passthrough, content that fetches attacker + resources for every recipient, markup injection into hosted UIs. +- Trust-model documentation violations: code behaving contrary to + what this policy states, where an operator relying on the policy + would reasonably expect otherwise. + +### 3.2 Out of Scope + +"Out of scope" here means "not a security vulnerability under this +policy." It does not mean "not worth reporting." Improvements to the +in-process heuristics, hardening ideas, and UX fixes are welcome as +regular issues or pull requests — we can always make the approval +gate catch more patterns, make redaction smarter, or tighten adapter +behavior. These items just don't go through the private-disclosure +channel and don't receive advisories. + +- **Bypasses of in-process heuristics (§2.3)** — approval-gate regex + bypasses, redaction bypasses, Skills Guard pattern bypasses, and + analogous reports against future heuristics. These components are + not boundaries; defeating them is not a vulnerability under this + policy. +- **Prompt injection that does not chain to a §3.1 outcome.** Getting + the LLM to emit unusual text or "ignore previous instructions" is + not itself a vulnerability; it becomes one only when it results in + something §3.1 describes. +- **Consequences of a chosen isolation posture.** Reports that a + code path operating within its posture's scope can do what that + posture permits are not vulnerabilities. Examples: shell tools + reaching host state under the local backend; code-execution or + file tools reaching host state under terminal-backend isolation + that only sandboxes shell; reports whose preconditions require + pre-existing write access to operator-owned configuration or + credential files (those are already inside the operator's trust + envelope). +- **Public exposure without external controls.** Exposing the + gateway or API to the public internet without authentication, + VPN, or firewall. +- **Documented break-glass settings.** Disabled approvals, local + backend in production, development profiles that bypass + hermes-home security, and similar operator-selected trade-offs. +- **Tool-level read/write restrictions on a posture where shell is + permitted.** If a path is reachable via the terminal tool, reports + that other file tools can reach it add nothing. --- -## 4. Deployment Hardening & Best Practices +## 4. Deployment Hardening -### Filesystem & Network -- **Production sandboxing:** Use container backends (`docker`, `modal`, `daytona`) instead of `local` for untrusted workloads. -- **File permissions:** Run as non-root (the Docker image uses UID 10000); protect credentials with `chmod 600 ~/.hermes/.env` on local installs. -- **Network exposure:** Do not expose the gateway or API server to the public internet without VPN, Tailscale, or firewall protection. SSRF protection is enabled by default across all gateway platform adapters (Telegram, Discord, Slack, Matrix, Mattermost, etc.) with redirect validation. Note: the local terminal backend does not apply SSRF filtering, as it operates within the trusted operator's environment. +The single most important hardening decision is matching isolation +(§2.1) to the trust of the content the agent will ingest. Beyond +that: -### Skills & Supply Chain -- **Skill installation:** Review Skills Guard reports (`tools/skills_guard.py`) before installing third-party skills. The audit log at `~/.hermes/skills/.hub/audit.log` tracks every install and removal. -- **MCP safety:** OSV malware checking runs automatically for `npx`/`uvx` packages before MCP server processes are spawned. -- **CI/CD:** GitHub Actions are pinned to full commit SHAs. The `supply-chain-audit.yml` workflow blocks PRs containing `.pth` files or suspicious `base64`+`exec` patterns. - -### Credential Storage -- API keys and tokens belong exclusively in `~/.hermes/.env` — never in `config.yaml` or checked into version control. -- The credential pool system (`agent/credential_pool.py`) handles key rotation and fallback. Credentials are resolved from environment variables, not stored in plaintext databases. +- Run the agent as a non-root user. The supplied container image + does this by default. +- Keep credentials in the operator credential file with tight + permissions, never in the main config, never in version control. + Under OpenShell, use its Provider store rather than an on-disk + credential file. +- Do not expose the gateway or API to the public internet without + VPN, Tailscale, or firewall protection. Under OpenShell, use the + network policy layer to restrict egress. +- Configure a caller allowlist for every gateway adapter you enable + (§2.4). +- Review third-party skills before install. Skills Guard reports and + the install audit log are the review surface. +- The OSV malware database is consulted before launching + ecosystem-resolved MCP servers. Additional supply-chain guards + on dependency and bundled-package changes run in CI; see + `CONTRIBUTING.md` for specifics. --- -## 5. Disclosure Process +## 5.

Adds two-tier gating for the kanban tool surface so dispatcher-spawned workers see only task-lifecycle tools (show/complete/block/heartbeat/ comment/create/link) while orchestrator profiles with `toolsets: [kanban]` also see board-routing tools (kanban_list, kanban_unblock). Workers shouldn't be enumerating or unblocking the board — they should close their own task via the lifecycle tools. Hiding board-routing tools from worker schemas keeps the worker focused and the toolset-isolation contract honest. Plus inherited from the same upstream commit: - 50/200 row bound on kanban_list with `truncated` + `next_limit` metadata. - Belt-and-suspenders runtime guard `_require_orchestrator_tool()` inside the orchestrator handlers in case a stale registration ever routes a worker to one of them. - Tests for the new gate, the stricter bound, and the fact that even a worker with `toolsets: [kanban]` in config still doesn't see board routing.

The adapter requires zero core edits — `Platform("line")` is auto-discovered via the bundled-plugin scan in `gateway/config.py`, and all hooks (setup, env-enablement, cron delivery, standalone send) are wired through `register_platform()` kwargs the way IRC and Teams do it. Highlights merged into one plugin: - **Reply token preferred, Push fallback.** Try the free reply token first (single-use, ~60s TTL); fall back to metered Push when the token is absent, expired, or rejected. (PR #21023) - **Slow-LLM Template Buttons postback.** When the LLM is still running past `LINE_SLOW_RESPONSE_THRESHOLD` (default 45s), the adapter burns the original reply token to send a "Get answer" button bubble. The user taps it to fetch the cached answer via a fresh reply token — also free. State machine: PENDING → READY → DELIVERED, ERROR for cancelled runs (orphan resolves to `LINE_INTERRUPTED_TEXT` after /stop). Set threshold to 0 to disable. (PR #18153) - **Three-allowlist gating** — separate user / group / room allowlists with `LINE_ALLOW_ALL_USERS=true` dev-only escape hatch. (PR #18153) - **Markdown URL preservation.** Strip bold/italic/code-fence/heading markers (LINE renders them literally) but keep `[label](url)` → `label (url)` so URLs stay tappable. (PR #18153) - **System-message bypass** for `⚡ Interrupting`, `⏳ Queued`, etc. — busy-acks reach the user as visible bubbles instead of being swallowed into the postback cache. (PR #18153) - **Media via public HTTPS URLs.** LINE doesn't accept binary uploads; images/audio/video must be HTTPS-reachable. The adapter serves registered tempfiles under `/line/media//` from the same aiohttp app. Allowed-roots traversal guard covers `tempfile.gettempdir()`, `/tmp` (→ `/private/tmp` on macOS), and `HERMES_HOME`. `LINE_PUBLIC_URL` overrides URL construction for setups behind tunnels/proxies. (PR #8398) - **5-message-per-call batching.** LINE rejects >5 messages per Reply/Push; smart-chunker caps text at 4500 chars per bubble. - **Inbound dedup** via `webhookEventId` LRU. (PR #21023) - **Self-message filter** via `/v2/bot/info` userId lookup. (PR #21023) - **Loading-animation indicator** wired to LINE's `chat/loading/start` endpoint, DM-only (LINE rejects it for groups/rooms). (PR #21023) - **Out-of-process cron delivery** via `_standalone_send`, so `deliver: line` cron jobs work even when cron runs detached from the gateway. - **Webhook hardening** — 1 MiB body cap, constant-time HMAC-SHA256 signature verification, dedup, scoped lock so two profiles can't bind the same channel. Validation ---------- - `scripts/run_tests.sh tests/gateway/test_line_plugin.py` → 73 passed in 1.05s - `scripts/run_tests.sh tests/gateway/test_line_plugin.py tests/gateway/test_irc_adapter.py tests/gateway/test_plugin_platform_interface.py tests/gateway/test_platform_registry.py tests/gateway/test_config.py` → 193 passed, 7 skipped - E2E import + register + signature roundtrip + `Platform("line")` bundled-plugin discovery verified against current `origin/main`. Closes the seven open LINE PRs (#18153, #16832, #6676, #21023, #14942, #14988, #8398) by superseding them with a single plugin-form implementation that takes the best idea from each.

Three subsections: - Pattern: subclass _keep_typing to layer mid-flight UX (with code) - Pattern: subclass send to route through a cache instead of sending - When this pattern is appropriate (vs. always-Push fallback) Plus a short pointer in gateway/platforms/ADDING_A_PLATFORM.md so tree-readers find the prose walkthrough on the docsite. Filed because the LINE plugin (PR #23197) was the first bundled adapter to need this pattern — every prior plugin (irc, teams, google_chat) handles slow responses with the default typing-loop and a regular send_text.

Closes the gap where plugins that needed bounded structured inference (receipts, CRM extraction, support classification) had to either bring their own provider keys or register a tool the agent had to call. New surface on PluginContext: - ctx.llm.complete(messages, ...) - ctx.llm.complete_structured(instructions, input, json_schema, ...) - async siblings ctx.llm.acomplete / acomplete_structured Backed by the existing auxiliary_client.call_llm pipeline — every provider, fallback chain, vision routing, and timeout policy Hermes already supports applies automatically. Trust gate (fail-closed by default): - plugins.entries..llm.allow_model_override - plugins.entries..llm.allowed_models (allowlist; '*' = any) - plugins.entries..llm.allow_agent_id_override - plugins.entries..llm.allow_profile_override Embedded model@profile shorthand goes through the same gate as explicit profile=, so it can't bypass the auth-profile policy. Conflicting explicit and embedded profiles fail closed. Also lands: - plugins/plugin-llm-example/ — reference plugin that registers /receipt-extract, demonstrating image+text structured input, jsonschema validation, and the trust-gate config. - website/docs/developer-guide/plugin-llm-access.md — full API docs. - 45 unit tests covering trust gates, JSON parsing, schema validation, image encoding, async surface, and config loading. Validation: - 2628 tests pass in tests/agent/ - E2E: bundled plugin loaded with isolated HERMES_HOME, slash command produced parsed JSON via stubbed call_llm - response_format extra_body wired correctly for both json_object and json_schema modes * docs(plugin-llm): rewrite quickstart and framing The quickstart now uses a meeting-notes-to-tasks example instead of a receipt extractor, and the page leads with hook-time / gateway pre-filter / scheduled-job framing rather than the OpenClaw KB/support/CRM/finance/migration enumeration that the original upstream PR used. Receipt example moved to a separate worked example link so the docs page itself doesn't echo any of the upstream framing. Also clarifies where ctx.llm fits in the broader plugin surface (table comparing register_tool / register_platform / register_hook / etc.) and what makes this lane different from auxiliary_client internals. No code change. * docs(plugin-llm): reframe as any LLM call, not just structured output The original draft leaned heavily on complete_structured() and made the chat lane (complete() / acomplete()) feel like a footnote. Restructure so: - The page title and description say 'any LLM call.' - The lead shows BOTH a plain chat call (error rewriter) AND a structured call (triage scorer) up top. - Quick start has two complete plugin examples — /tldr (chat) and /paste-to-tasks (structured). - New 'When to use which' table for choosing complete() vs complete_structured() vs the async siblings. - Trust-gate sections explicitly note 'all four methods,' and the request-shaping list calls out chat-only fields (messages) and structured-only fields (instructions, input, json_schema) alongside each other. - The 'Where this fits' section now says 'for any reason, structured or not.' The receipt-extractor reference plugin still exists under plugins/plugin-llm-example/ — but the docs page no longer treats it as the canonical surface example. It's now described as 'a third worked example, this time with image input.' No code change. * feat(plugin-llm): split provider/model into independent explicit kwargs The first cut accepted a single 'provider/model' slug on every method and split it internally. That looked clean but broke under live test: the model-override path tried to use the slug's vendor prefix as a literal Hermes provider id, which silently switched the user off their aggregator (e.g. plugin asks for 'openai/gpt-4o-mini' on a user who routes through OpenRouter — host attempted to call the 'openai' provider directly, failed because OPENAI_API_KEY wasn't set). New shape mirrors the host's main config: ctx.llm.complete( messages=[...], provider='openrouter', # gated, optional model='openai/gpt-4o-mini', # gated, optional profile='work', # gated, optional ... ) Each is independently gated by its own allow_*_override flag. Granting model-override does NOT auto-grant provider-override. Allowlists are now per-axis (allowed_providers, allowed_models) matched literally against whatever string the plugin sends. Dropped 'model@profile' embedded-suffix shorthand entirely. Hermes doesn't use that pattern anywhere else; profile= is its own kwarg. Live E2E (against real OpenRouter via Teknium's config) confirms: - zero-config call works - default-deny blocks each override with a helpful error - model-only override stays on user's active provider (the bug) - provider+model override switches cleanly - allowlist refuses non-listed entries - structured output round-trip parses + schema-validates Tests: 49 cases (up from 45); all green. Docs updated to match the new shape, including a 'most plugins never need this section' callout on the trust-gate config block. * fix+cleanup(plugin-llm): real attribution, hook-mode coverage, move example out of core Three integration fixes for the ctx.llm surface: 1. Attribution bug — result.provider and result.model now reflect what call_llm actually used, not placeholder fallbacks ('auto', 'default'). New _resolve_attribution() helper: - explicit overrides win (what the call targeted) - response.model wins for the recorded model (provider canonicalisation: 'gpt-4o' → 'gpt-4o-2024-08-06' etc.) - falls back to _read_main_provider() / _read_main_model() when no override is set, so audit logs reflect the user's active main provider/model - 'auto' / 'default' only when EVERYTHING is empty Live verified: zero-config call now records provider='openrouter', model='anthropic/claude-4.7-opus-20260416' instead of provider='auto', model='default'. 2. Hook-mode coverage — TestHookMode confirms ctx.llm.complete works from inside a registered post_tool_call callback. The docs page promised hook integration; now there's a test that exercises the lazy-import path through the real invoke_hook machinery. Two cases: traceback-rewrite hook with conditional ctx.llm.complete, and minimal hook regression for the sync-hook + sync-llm path. 3. Reference plugin moved out of core. plugins/plugin-llm-example/ is gone from hermes-agent — it now lives in the new NousResearch/hermes-example-plugins companion repo. The docs page links there. Hermes' bundled plugins should be plugins users actually run; reference / docs-companion plugins live externally. Test count: 56 (up from 49). Wider sweep on tests/hermes_cli/ + tests/gateway/ + tests/tools/ + tests/agent/ shows 16770 passing; the 12 failures are all pre-existing on origin/main (verified by stashing this branch's changes and re-running) — kanban-boards, delegate-task, gateway-restart, tts-routing — none touch the plugin_llm surface. * chore(plugins): move all example plugins to companion repo Reference / docs-companion plugins now live exclusively in NousResearch/hermes-example-plugins, not bundled with the core repo: - example-dashboard - strike-freedom-cockpit A new fourth example, plugin-llm-async-example, was added to that repo demonstrating ctx.llm's async surface (acomplete()) with asyncio.gather() — registers /translate : which fires forward translation + sentiment classifier in parallel, then a back-translation for QA. Live-tested at 2.5s for three real provider round-trips (would be ~5-6s sequential). Docs updated: - developer-guide/plugin-llm-access.md links both sync and async examples in the Reference section - user-guide/features/extending-the-dashboard.md repoints both demo sections to the companion repo with corrected install paths - user-guide/features/built-in-plugins.md drops the two demo rows - AGENTS.md notes that example plugins live in the companion repo Net: hermes-agent's plugins/ directory now contains only plugins users actually run (memory providers, dashboard tabs that ship real features, the disk-cleanup hook, platform adapters). All four demo / reference plugins live externally where they can be cloned on demand instead of inflating the core install. --- AGENTS.md | 12 +- agent/plugin_llm.py | 1046 +++++++++++++++++ hermes_cli/plugins.py | 21 + .../example-dashboard/dashboard/dist/index.js | 119 -- .../example-dashboard/dashboard/manifest.json | 14 - .../example-dashboard/dashboard/plugin_api.py | 14 - plugins/strike-freedom-cockpit/README.md | 70 -- .../dashboard/dist/index.js | 309 ----- .../dashboard/manifest.json | 14 - .../theme/strike-freedom.yaml | 126 -- tests/agent/test_plugin_llm.py | 991 ++++++++++++++++ .../docs/developer-guide/plugin-llm-access.md | 465 ++++++++ .../user-guide/features/built-in-plugins.md | 2 - .../features/extending-the-dashboard.md | 12 +- website/docs/user-guide/features/plugins.md | 1 + website/sidebars.ts | 1 + 16 files changed, 2540 insertions(+), 677 deletions(-) create mode 100644 agent/plugin_llm.py delete mode 100644 plugins/example-dashboard/dashboard/dist/index.js delete mode 100644 plugins/example-dashboard/dashboard/manifest.json delete mode 100644 plugins/example-dashboard/dashboard/plugin_api.py delete mode 100644 plugins/strike-freedom-cockpit/README.md delete mode 100644 plugins/strike-freedom-cockpit/dashboard/dist/index.js delete mode 100644 plugins/strike-freedom-cockpit/dashboard/manifest.json delete mode 100644 plugins/strike-freedom-cockpit/theme/strike-freedom.yaml create mode 100644 tests/agent/test_plugin_llm.py create mode 100644 website/docs/developer-guide/plugin-llm-access.md diff --git a/AGENTS.md b/AGENTS.md index 0c8550d459d..d8ba934c521 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -540,10 +540,14 @@ Full authoring guide: `website/docs/developer-guide/model-provider-plugin.md`. ### Dashboard / context-engine / image-gen plugin directories -`plugins/context_engine/`, `plugins/image_gen/`, `plugins/example-dashboard/`, -etc. follow the same pattern (ABC + orchestrator + per-plugin directory). -Context engines plug into `agent/context_engine.py`; image-gen providers -into `agent/image_gen_provider.py`. +`plugins/context_engine/`, `plugins/image_gen/`, etc. follow the same +pattern (ABC + orchestrator + per-plugin directory).
