Two pluggable surfaces were mentioned in the interfaces map without a
real authoring guide behind them:
1. **Image-gen backends** — only had 'See bundled examples' pointers.
Now a full developer-guide/image-gen-provider-plugin.md (270 lines)
mirroring the memory/context/model provider docs:
- How discovery works, directory structure, plugin.yaml
- ImageGenProvider ABC with every overridable method
(name, display_name, is_available, list_models, default_model,
get_setup_schema, generate)
- Full authoring walkthrough with a working MyBackendImageGenProvider
- Response-format reference (success_response / error_response)
- Handling b64 vs URL output (save_b64_image helper)
- User overrides at ~/.hermes/plugins/image_gen/<name>/
- Testing recipe + pip distribution
- Reference examples (openai, openai-codex, xai)
2. **Skill taps** — features/skills.md mentioned the CLI commands but
never explained the repo contract for publishing a tap. Added
'Publishing a custom skill tap' section under Skills Hub covering:
- Repo layout (skills/<name>/SKILL.md by default)
- Minimal working example
- Non-default path configuration (taps.json)
- Installing individual skills without subscribing
- Trust-level handling
- Full tap management CLI + in-session /skills tap commands
Wired into:
- website/sidebars.ts: image-gen-provider-plugin added to Extending group
- website/docs/user-guide/features/plugins.md: pluggable interfaces
table + 'What plugins can do' table now link to the real guides
instead of 'See bundled examples'
- website/docs/guides/build-a-hermes-plugin.md: top info map and
inline sub-sections updated, 'Full guide:' line added to
image-gen block, tap section mentions publishing
Verified: docusaurus build SUCCESS, new page renders at
/docs/developer-guide/image-gen-provider-plugin, anchor
#publishing-a-custom-skill-tap resolves from plugins.md +
build-a-hermes-plugin.md. Pre-existing zh-Hans broken links unchanged.
* docs(providers): add model-provider-plugin authoring guide + fix stale refs
New docs:
- website/docs/developer-guide/model-provider-plugin.md — full authoring
guide (directory layout, minimal example, ProviderProfile fields,
overridable hooks, user overrides, api_mode selection, auth types,
testing, pip distribution)
- Wired into website/sidebars.ts under 'Extending'
- Cross-references added in:
- guides/build-a-hermes-plugin.md (tip block)
- developer-guide/adding-providers.md
- developer-guide/provider-runtime.md
User guide:
- user-guide/features/plugins.md: Plugin types table grows from 3 to 4
with 'Model providers' row
Stale comment cleanup (providers/*.py → plugins/model-providers/<name>/):
- hermes_cli/main.py:_is_profile_api_key_provider docstring
- hermes_cli/doctor.py:_build_apikey_providers_list docstring
- hermes_cli/auth.py: PROVIDER_REGISTRY + alias auto-extension comments
- hermes_cli/models.py: CANONICAL_PROVIDERS auto-extension comment
AGENTS.md:
- Project-structure tree: added plugins/model-providers/ row
- New section: 'Model-provider plugins' explaining discovery, override
semantics, PluginManager integration, kind auto-coerce heuristic
Verified: docusaurus build succeeds, new page renders, all 3 cross-links
resolve. 347/347 targeted tests pass (tests/providers/,
tests/hermes_cli/test_plugins.py, tests/hermes_cli/test_runtime_provider_resolution.py,
tests/run_agent/test_provider_parity.py).
* docs(plugins): add 'pluggable interfaces at a glance' maps to plugins.md + build-a-hermes-plugin
Devs landing on either the user-guide plugin page or the build-a-plugin
guide now get an upfront table of every distinct pluggable surface with
a link to the right authoring doc. Previously they'd have to read the
full general-plugin guide to discover that model providers / platforms
/ memory / context engines are separate systems.
user-guide/features/plugins.md:
- New 'Pluggable interfaces — where to go for each' section below the
existing 4-kinds table
- 10 rows covering every register_* surface (tool, hook, slash command,
CLI subcommand, skill, model provider, platform, memory, context
engine, image-gen)
- Explicit note: TTS/STT are NOT plugin-extensible yet — documented
with a pointer to the current config.yaml 'command providers' pattern
and a note that register_tts_provider()/register_stt_provider() may
come later
guides/build-a-hermes-plugin.md:
- New :::info 'Not sure which guide you need?' map at the top so devs
see all pluggable interfaces before investing in this 737-line
general-plugin walkthrough
- Existing bottom :::tip expanded to include platform adapters alongside
model/memory/context plugins
Verified:
- All 8 cross-doc links in the new plugins.md table resolve in a
docusaurus build (SUCCESS, no new broken links)
- TTS link corrected (features/voice → features/tts; latter exists)
- Pre-existing broken links/anchors (cron-script-only, llms.txt,
adding-platform-adapters#step-by-step-checklist) are unchanged
* docs(plugins): correct TTS/STT pluggability \u2014 they ARE plugins (command-providers)
Previous commit incorrectly said TTS/STT 'aren't plugin-extensible'. They
are, via the config-driven command-provider pattern \u2014 any CLI that reads
text and writes audio (or vice versa for STT) is automatically a plugin
with zero Python. The tts.md docs cover this extensively and I missed it.
plugins.md:
- TTS row: 'Config-driven (not a Python plugin)', points at
tts.md#custom-command-providers
- STT row: points at tts.md#voice-message-transcription-stt (STT docs
live in tts.md despite the filename)
- Expanded note: TTS/STT use config-driven shell-command templates as
their plugin surface (full tts.providers.<name> registry for TTS;
HERMES_LOCAL_STT_COMMAND escape hatch for STT)
- Any CLI that reads/writes files is automatically a plugin \u2014 no Python
register_* API needed
- Future register_tts_provider()/register_stt_provider() hooks mentioned
as nice-to-have for SDK/streaming cases, not as the primary story
build-a-hermes-plugin.md:
- Same map update: TTS/STT rows explicit, footer note corrected
Verified:
- tts.md anchors (custom-command-providers, voice-message-transcription-stt)
exist and resolve in docusaurus build (SUCCESS, no new broken links)
* docs(plugins): expand pluggable interfaces table with MCP / event hooks / shell hooks / skill taps
Broadened the scope beyond Python register_* hooks. Hermes has MULTIPLE
plugin-style extension surfaces; they're now all in one table instead of
being scattered across feature docs.
Added rows for:
- **MCP servers** — config.yaml mcp_servers.<name> auto-registers external
tools from any MCP server. Huge extensibility surface, previously not
linked from the plugin map.
- **Gateway event hooks** — drop HOOK.yaml + handler.py into
~/.hermes/hooks/<name>/ to fire on gateway:startup, session:*, agent:*,
command:* events. Separate from Python plugin hooks.
- **Shell hooks** — hooks: block in config.yaml runs shell commands on
events (notifications, auditing, etc.).
- **Skill sources (taps)** — hermes skills tap add <repo> to pull in new
skill registries beyond the built-in sources.
Both docs updated:
- user-guide/features/plugins.md: table column renamed to 'How' (mixes
Python API + config-driven + drop-in-dir surfaces accurately)
- guides/build-a-hermes-plugin.md: :::info map at top mirrors the new
surfaces with a forward-link to the consolidated table
Note block rewritten: instead of singling out TTS/STT as the 'different
style' exception, now honestly describes that Hermes deliberately
supports three plugin styles — Python APIs, config-driven commands, and
drop-in manifest directories — and devs should pick the one that fits
their integration.
Not included (considered and rejected):
- Transport layer (register_transport) — internal, not user-facing
- Tool-call parsers — internal, VLLM phase-2 thing
- Cloud browser providers — hardcoded registry, not drop-in yet
- Terminal backends — hardcoded if/elif, not drop-in yet
- Skill sources (the ABC) — hardcoded list, only taps are user-extensible
Verified:
- All 5 new anchors resolve (gateway-event-hooks, shell-hooks, skills-hub,
custom-command-providers, voice-message-transcription-stt)
- Docusaurus build SUCCESS, zero new broken links
- Same 3 pre-existing broken links on main (cron-script-only, llms.txt,
adding-platform-adapters#step-by-step-checklist)
* docs(plugins): cover every pluggable surface in both the overview and how-to
Both plugins.md and build-a-hermes-plugin.md now cover every extension
surface end-to-end \u2014 general plugin APIs, specialized plugin types,
config-driven surfaces \u2014 with concrete authoring patterns for each.
plugins.md:
- 'What plugins can do' table grows from 9 rows (general ctx.register_*
only) to 14 rows covering register_platform, register_image_gen_provider,
register_context_engine, MemoryProvider subclass, register_provider
(model). Each row links to its full authoring guide.
- New 'Plugin sub-categories' section under Plugin Discovery explains
how plugins/platforms/, plugins/image_gen/, plugins/memory/,
plugins/context_engine/, plugins/model-providers/ are routed to
different loaders \u2014 PluginManager vs the per-category own-loader
systems.
- Explicit mention of user-override semantics at
~/.hermes/plugins/model-providers/ and ~/.hermes/plugins/memory/.
build-a-hermes-plugin.md:
- New '## Specialized plugin types' section (5 sub-sections):
- Model provider plugins \u2014 ProviderProfile + plugin.yaml example,
auto-wiring summary, link to full guide
- Platform plugins \u2014 BasePlatformAdapter + register_platform() skeleton
- Memory provider plugins \u2014 MemoryProvider subclass example
- Context engine plugins \u2014 ContextEngine subclass example
- Image-generation backends \u2014 ImageGenProvider + kind: backend example
- New '## Non-Python extension surfaces' section (5 sub-sections):
- MCP servers \u2014 config.yaml mcp_servers.<name> example
- Gateway event hooks \u2014 HOOK.yaml + handler.py example
- Shell hooks \u2014 hooks: block in config.yaml example
- Skill sources (taps) \u2014 hermes skills tap add example
- TTS / STT command templates \u2014 tts.providers.<name> with type: command
- Distribute via pip / NixOS promoted from ### to ## (they were orphaned
after the reorganization)
Each specialized / non-Python section has a concrete, copy-pasteable
example plus a 'Full guide:' link to the authoritative doc. Devs arriving
at the build-a-hermes-plugin guide now see every extension surface at
their disposal, not just the general tool/hook/slash-command surface.
Verified:
- Docusaurus build SUCCESS, zero new broken links
- All new cross-links (developer-guide/model-provider-plugin,
adding-platform-adapters, memory-provider-plugin, context-engine-plugin,
user-guide/features/mcp, skills#skills-hub, hooks#gateway-event-hooks,
hooks#shell-hooks, tts#custom-command-providers,
tts#voice-message-transcription-stt) resolve
- Same 3 pre-existing broken links on main (cron-script-only, llms.txt,
adding-platform-adapters#step-by-step-checklist)
* docs(plugins): fix opt-in inconsistency — not every plugin is gated
The 'Every plugin is disabled by default' statement was wrong. Several
plugin categories intentionally bypass plugins.enabled:
- Bundled platform plugins (IRC, Teams) auto-load so shipped gateway
channels are available out of the box. Activation per channel is via
gateway.platforms.<name>.enabled.
- Bundled backends (plugins/image_gen/*) auto-load so the default
backend 'just works'. Selection via <category>.provider config.
- Memory providers are all discovered; one is active via memory.provider.
- Context engines are all discovered; one is active via context.engine.
- Model providers: all 33 discovered at first get_provider_profile();
user picks via --provider / config.
The plugins.enabled allow-list specifically gates:
- Standalone plugins (general tools/hooks/slash commands)
- User-installed backends
- User-installed platforms (third-party gateway adapters)
- Pip entry-point backends
Which matches the actual code in hermes_cli/plugins.py:737 where the
bundled+backend/platform check bypasses the allow-list.
Rewrote '## Plugins are opt-in' to:
- Retitle to 'Plugins are opt-in (with a few exceptions)'
- Narrow opening claim to 'General plugins and user-installed backends
are disabled by default'
- Added 'What the allow-list does NOT gate' subsection with a full
table of which bypass the gate and how they're activated instead
- Fixed migration section wording (bundled platform/backend plugins
never needed grandfathering)
Verified: docusaurus build SUCCESS, zero new broken links.
Steers custom tool creation toward the plugin route by default.
The adding-tools.md guide is now explicitly for built-in core Hermes
tools only.
Key fixes:
- Plugin quickstart: ctx.register_tool() now uses correct keyword-arg
API (name=, toolset=, schema=, handler=) instead of broken 3-arg call
- Handler signature: (params, **kwargs) instead of (params)
- Handler return: json.dumps({...}) instead of plain string
- AGENTS.md: mentions plugin route before built-in tool instructions
- learning-path.md: plugins listed before core tool development
- contributing.md: separates plugin vs core tool paths
Based on PR #13138 by @helix4u.
Broad drift audit against origin/main (b52b63396).
Reference pages (most user-visible drift):
- slash-commands: add /busy, /curator, /footer, /indicator, /redraw, /steer
that were missing; drop non-existent /terminal-setup; fix /q footnote
(resolves to /queue, not /quit); extend CLI-only list with all 24
CLI-only commands in the registry
- cli-commands: add dedicated sections for hermes curator / fallback /
hooks (new subcommands not previously documented); remove stale
hermes honcho standalone section (the plugin registers dynamically
via hermes memory); list curator/fallback/hooks in top-level table;
fix completion to include fish
- toolsets-reference: document the real 52-toolset count; split browser
vs browser-cdp; add discord / discord_admin / spotify / yuanbao;
correct hermes-cli tool count from 36 to 38; fix misleading claim
that hermes-homeassistant adds tools (it's identical to hermes-cli)
- tools-reference: bump tool count 55 -> 68; add 7 Spotify, 5 Yuanbao,
2 Discord toolsets; move browser_cdp/browser_dialog to their own
browser-cdp toolset section
- environment-variables: add 40+ user-facing HERMES_* vars that were
undocumented (--yolo, --accept-hooks, --ignore-*, inference model
override, agent/stream/checkpoint timeouts, OAuth trace, per-platform
batch tuning for Telegram/Discord/Matrix/Feishu/WeCom, cron knobs,
gateway restart/connect timeouts); dedupe the Cron Scheduler section;
replace stale QQ_SANDBOX with QQ_PORTAL_HOST
User-guide (top level):
- cli.md: compression preserves last 20 turns, not 4 (protect_last_n: 20)
- configuration.md: display.platforms is the canonical per-platform
override key; tool_progress_overrides is deprecated and auto-migrated
- profiles.md: model.default is the config key, not model.model
- sessions.md: CLI/TUI session IDs use 6-char hex, gateway uses 8
- checkpoints-and-rollback.md: destructive-command list now matches
_DESTRUCTIVE_PATTERNS (adds rmdir, cp, install, dd)
- docker.md: the container runs as non-root hermes (UID 10000) via
gosu; fix install command (uv pip); add missing --insecure on the
dashboard compose example (required for non-loopback bind)
- security.md: systemctl danger pattern also matches 'restart'
- index.md: built-in tool count 47 -> 68
- integrations/index.md: 6 STT providers, 8 memory providers
- integrations/providers.md: drop fictional dashscope/qwen aliases
Features:
- overview.md: 9 image models (not 8), 9 TTS providers (not 5),
8 memory providers (Supermemory was missing)
- tool-gateway.md: 9 image models
- tools.md: extend common-toolsets list with search / messaging /
spotify / discord / debugging / safe
- fallback-providers.md: add 6 real providers from PROVIDER_REGISTRY
(lmstudio, kimi-coding-cn, stepfun, alibaba-coding-plan,
tencent-tokenhub, azure-foundry)
- plugins.md: Available Hooks table now includes on_session_finalize,
on_session_reset, subagent_stop
- built-in-plugins.md: add the 7 bundled plugins the page didn't
mention (spotify, google_meet, three image_gen providers, two
dashboard examples)
- web-dashboard.md: add --insecure and --tui flags
- cron.md: hermes cron create takes positional schedule/prompt, not
flags
Messaging:
- telegram.md: TELEGRAM_WEBHOOK_SECRET is now REQUIRED when
TELEGRAM_WEBHOOK_URL is set (gateway refuses to start without it
per GHSA-3vpc-7q5r-276h). Biggest user-visible drift in the batch.
- discord.md: HERMES_DISCORD_TEXT_BATCH_SPLIT_DELAY_SECONDS default
is 2.0, not 0.1
- dingtalk.md: document DINGTALK_REQUIRE_MENTION /
FREE_RESPONSE_CHATS / MENTION_PATTERNS / HOME_CHANNEL /
ALLOW_ALL_USERS that the adapter supports
- bluebubbles.md: drop fictional BLUEBUBBLES_SEND_READ_RECEIPTS env
var; the setting lives in platforms.bluebubbles.extra only
- qqbot.md: drop dead QQ_SANDBOX; add real QQ_PORTAL_HOST and
QQ_GROUP_ALLOWED_USERS
- wecom-callback.md: replace 'hermes gateway start' (service-only)
with 'hermes gateway' for first-time setup
Developer-guide:
- architecture.md: refresh tool/toolset counts (61/52), terminal
backend count (7), line counts for run_agent.py (~13.7k), cli.py
(~11.5k), main.py (~10.4k), setup.py (~3.5k), gateway/run.py
(~12.2k), mcp_tool.py (~3.1k); add yuanbao adapter, bump platform
adapter count 18 -> 20
- agent-loop.md: run_agent.py line count 10.7k -> 13.7k
- tools-runtime.md: add vercel_sandbox backend
- adding-tools.md: remove stale 'Discovery import added to
model_tools.py' checklist item (registry auto-discovery)
- adding-platform-adapters.md: mark send_typing / get_chat_info as
concrete base methods; only connect/disconnect/send are abstract
- acp-internals.md: ACP sessions now persist to SessionDB
(~/.hermes/state.db); acp.run_agent call uses
use_unstable_protocol=True
- cron-internals.md: gateway runs scheduler in a dedicated background
thread via _start_cron_ticker, not on a maintenance cycle; locking
is cross-process via fcntl.flock (Unix) / msvcrt.locking (Windows)
- gateway-internals.md: gateway/run.py ~12k lines
- provider-runtime.md: cron DOES support fallback (run_job reads
fallback_providers from config)
- session-storage.md: SCHEMA_VERSION = 11 (not 9); add migrations
10 and 11 (trigram FTS, inline-mode FTS5 re-index); add
api_call_count column to Sessions DDL; document messages_fts_trigram
and state_meta in the architecture tree
- context-compression-and-caching.md: remove the obsolete 'context
pressure warnings' section (warnings were removed for causing
models to give up early)
- context-engine-plugin.md: compress() signature now includes
focus_topic param
- extending-the-cli.md: _build_tui_layout_children signature now
includes model_picker_widget; add to default layout
Also fixed three pre-existing broken links/anchors the build warned
about (docker.md -> api-server.md, yuanbao.md -> cron-jobs.md and
tips#background-tasks, nix-setup.md -> #container-aware-cli).
Regenerated per-skill pages via website/scripts/generate-skill-docs.py
so catalog tables and sidebar are consistent with current SKILL.md
frontmatter.
docusaurus build: clean, no broken links or anchors.
* feat(nix): parameterize dependency-groups in python.nix
* refactor(nix): extract package to callPackage-able hermes-agent.nix
Makes the package overridable via .override{} and adds
extraPythonPackages parameter for PYTHONPATH injection.
Includes build-time collision check using PEP 503 name
canonicalization.
* feat(nix): add overlay for external NixOS consumption
External flakes can now add overlays = [ inputs.hermes-agent.overlays.default ]
to get pkgs.hermes-agent with full .override support.
* test(nix): add check for extraPythonPackages PYTHONPATH injection
Verifies wrapper has PYTHONPATH when extras provided, and
base package has no PYTHONPATH without extras.
* feat(nix): add extraPlugins option for directory-based plugins
Symlinks plugin packages into HERMES_HOME/plugins/ at activation time.
Validates plugin.yaml presence. Asserts unique plugin names at eval time.
Hermes discovers them automatically via its directory scan.
* feat(nix): add extraPythonPackages option for entry-point plugins
Overrides the hermes package with PYTHONPATH injection when
extraPythonPackages is non-empty. Plugin .dist-info directories
become visible to importlib.metadata for entry-point discovery.
Works in both native systemd and container modes.
* docs: add NixOS declarative plugin installation to nix-setup, plugins, and build-a-plugin guides
- nix-setup.md: new Plugins section with extraPlugins/extraPythonPackages
examples, overlay usage, collision checking note, options reference rows
- plugins.md: Nix row in discovery table, NixOS declarative plugins section
- build-a-hermes-plugin.md: Distribute for NixOS section after pip section
* fix: address review feedback — remove unrelated umask, fix fetchFromGitHub naming, simplify checks
- Remove accidentally introduced umask/migration changes (unrelated to plugins)
- Add pluginName helper, fix fetchFromGitHub producing name='source'
- Show name= in extraPlugins example docs
- Simplify checks.nix: use hermes-agent.override instead of re-callPackage
- Fix fragile grep shell logic in checks
* refactor: address simplify feedback — lib.getName, drop unused inputs', Python list for extras
- Use lib.getName instead of custom pluginName helper
- Drop unused inputs' from checks.nix perSystem args
- Pass extraPythonPackages as Python list literal instead of colon-split string
* fix: walk propagatedBuildInputs for plugin PYTHONPATH and collision check
Uses python312.pkgs.requiredPythonModules to resolve the full transitive
closure of extraPythonPackages. Without this, a plugin with third-party
deps (e.g. requests) would fail at runtime if those deps weren't already
in the sealed uv2nix venv. The collision check now also scans the full
closure, catching transitive conflicts.
* cleanup: fold plugins into subdir loop, use find for symlink cleanup, inline lib.getName
- Add 'plugins' to the existing cron/sessions/logs/memories subdir loop
instead of a separate mkdir/chown/chmod block
- Replace fragile for-glob with find -delete for stale symlink cleanup
- Inline lib.getName at both call sites, remove pluginName wrapper
Follow-up to aeff6dfe:
- Fix semantic error in VALID_HOOKS inline comment ("after core auth" ->
"before auth"). Hook intentionally runs BEFORE auth so plugins can
handle unauthorized senders without triggering the pairing flow.
- Fix wrong class name in the same comment (HermesGateway ->
GatewayRunner, matching gateway/run.py).
- Add a full ### pre_gateway_dispatch section in
website/docs/user-guide/features/hooks.md (matches the pattern of
every other plugin hook: signature, params table, fires-where,
return-value table, use cases, two worked examples) plus a row in
the quick-reference table.
- Add the anchor link on the plugins.md table row so it matches the
other hook entries.
No code behavior change.
Introduces a new plugin hook `pre_gateway_dispatch` fired once per
incoming MessageEvent in `_handle_message`, after the internal-event
guard but before the auth / pairing chain. Plugins may return a dict
to influence flow:
{"action": "skip", "reason": "..."} -> drop (no reply)
{"action": "rewrite", "text": "..."} -> replace event.text
{"action": "allow"} / None -> normal dispatch
Motivation: gateway-level message-flow patterns that don't fit cleanly
into any single adapter — e.g. listen-only group-chat windows (buffer
ambient messages, collapse on @mention), or human-handover silent
ingest (record messages while an owner handles the chat manually).
Today these require forking core; with this hook they can live in a
single profile-agnostic plugin.
Hook runs BEFORE auth so plugins can handle unauthorized senders
(e.g. customer-service handover ingest) without triggering the
pairing-code flow. Exceptions in plugin callbacks are caught and
logged; the first non-None action dict wins, remaining results are
ignored.
Includes:
- `VALID_HOOKS` entry + inline doc in `hermes_cli/plugins.py`
- Invocation block in `gateway/run.py::_handle_message`
- 5 new tests in `tests/gateway/test_pre_gateway_dispatch.py`
(skip, rewrite, allow, exception safety, internal-event bypass)
- 2 additional tests in `tests/hermes_cli/test_plugins.py`
- Table entry in `website/docs/user-guide/features/plugins.md`
Made-with: Cursor
Plugins now require explicit consent to load. Discovery still finds every
plugin — user-installed, bundled, and pip — so they all show up in
`hermes plugins` and `/plugins`, but the loader only instantiates
plugins whose name appears in `plugins.enabled` in config.yaml. This
removes the previous ambient-execution risk where a newly-installed or
bundled plugin could register hooks, tools, and commands on first run
without the user opting in.
The three-state model is now explicit:
enabled — in plugins.enabled, loads on next session
disabled — in plugins.disabled, never loads (wins over enabled)
not enabled — discovered but never opted in (default for new installs)
`hermes plugins install <repo>` prompts "Enable 'name' now? [y/N]"
(defaults to no). New `--enable` / `--no-enable` flags skip the prompt
for scripted installs. `hermes plugins enable/disable` manage both lists
so a disabled plugin stays explicitly off even if something later adds
it to enabled.
Config migration (schema v20 → v21): existing user plugins already
installed under ~/.hermes/plugins/ (minus anything in plugins.disabled)
are auto-grandfathered into plugins.enabled so upgrades don't silently
break working setups. Bundled plugins are NOT grandfathered — even
existing users have to opt in explicitly.
Also: HERMES_DISABLE_BUNDLED_PLUGINS env var removed (redundant with
opt-in default), cmd_list now shows bundled + user plugins together with
their three-state status, interactive UI tags bundled entries
[bundled], docs updated across plugins.md and built-in-plugins.md.
Validation: 442 plugin/config tests pass. E2E: fresh install discovers
disk-cleanup but does not load it; `hermes plugins enable disk-cleanup`
activates hooks; migration grandfathers existing user plugins correctly
while leaving bundled plugins off.
The original name was cute but non-obvious; disk-cleanup says what it
does. Plugin directory, script, state path, log lines, slash command,
and test module all renamed. No user-visible state exists yet, so no
migration path is needed.
New website page "Built-in Plugins" documents the <repo>/plugins/<name>/
source, how discovery interacts with user/project plugins, the
HERMES_DISABLE_BUNDLED_PLUGINS escape hatch, disk-cleanup's hook
behaviour and deletion rules, and guidance on when a plugin belongs
bundled vs. user-installable. Added to the Features → Core sidebar next
to the main Plugins page, with a cross-reference from plugins.md.
* feat: implement register_command() on plugin context
Complete the half-built plugin slash command system. The dispatch
code in cli.py and gateway/run.py already called
get_plugin_command_handler() but the registration side was never
implemented.
Changes:
- Add register_command() to PluginContext — stores handler,
description, and plugin name; normalizes names; rejects conflicts
with built-in commands
- Add _plugin_commands dict to PluginManager
- Add commands_registered tracking on LoadedPlugin
- Add get_plugin_command_handler() and get_plugin_commands()
module-level convenience functions
- Fix commands.py to use actual plugin description in Telegram
bot menu (was hardcoded 'Plugin command')
- Add plugin commands to SlashCommandCompleter autocomplete
- Show command count in /plugins display
- 12 new tests covering registration, conflict detection,
normalization, handler dispatch, and introspection
Closes#10495
* docs: add register_command() to plugin guides
- Build a Plugin guide: new 'Register slash commands' section with
full API reference, comparison table vs register_cli_command(),
sync/async examples, and conflict protection docs
- Features/Plugins page: add slash commands to capabilities table
and plugin types summary
Add ctx.register_skill() API so plugins can ship SKILL.md files under
a 'plugin:skill' namespace, preventing name collisions with built-in
Hermes skills. skill_view() detects the ':' separator and routes to
the plugin registry while bare names continue through the existing
flat-tree scan unchanged.
Key additions:
- agent/skill_utils: parse_qualified_name(), is_valid_namespace()
- hermes_cli/plugins: PluginContext.register_skill(), PluginManager
skill registry (find/list/remove)
- tools/skills_tool: qualified name dispatch in skill_view(),
_serve_plugin_skill() with full guards (disabled, platform,
injection scan), bundle context banner with sibling listing,
stale registry self-heal
- Hoisted _INJECTION_PATTERNS to module level (dedup)
- Updated skill_view schema description
Based on PR #9334 by N0nb0at. Lean P1 salvage — omits autogen shim
(P2) for a simpler first merge.
Closes#8422
Updates the plugin build guide and features page to reflect the
interactive env var prompting added in PR #5470. Documents the rich
manifest format (name/description/url/secret) alongside the simple
string format.
Plugin context from pre_llm_call hooks was injected into the system
prompt, breaking the prompt cache prefix every turn when content
changed (typical for memory plugins). Now all plugin context goes
into the current turn's user message — the system prompt stays
identical across turns, preserving cached tokens.
The system prompt is reserved for Hermes internals. Plugins
contribute context alongside the user's input.
Also adds comprehensive documentation for all 6 plugin hooks:
pre_tool_call, post_tool_call, pre_llm_call, post_llm_call,
on_session_start, on_session_end — each with full callback
signatures, parameter tables, firing conditions, and examples.
Supersedes #5138 which identified the same cache-busting bug
and proposed an uncached system suffix approach. This fix goes
further by removing system prompt injection entirely.

Major reorganization of the documentation site for better discoverability
and navigation. 94 pages across 8 top-level sections (was 5).
Structural changes:
- Promote Features from 3-level-deep subcategory to top-level section
with new Overview hub page categorizing all 26 feature pages
- Promote Messaging Platforms from User Guide subcategory to top-level
section, add platform comparison matrix (13 platforms x 7 features)
- Create new Integrations section with hub page, grouping MCP, ACP,
API Server, Honcho, Provider Routing, Fallback Providers
- Extract AI provider content (626 lines) from configuration.md into
dedicated integrations/providers.md — configuration.md drops from
1803 to 1178 lines
- Subcategorize Developer Guide into Architecture, Extending, Internals
- Rename "User Guide" to "Using Hermes" for top-level items
Orphan fixes (7 pages now reachable via sidebar):
- build-a-hermes-plugin.md added to Guides
- sms.md added to Messaging Platforms
- context-references.md added to Features > Core
- plugins.md added to Features > Core
- git-worktrees.md added to Using Hermes
- checkpoints-and-rollback.md added to Using Hermes
- checkpoints.md (30-line stub) deleted, superseded by
checkpoints-and-rollback.md (203 lines)
New files:
- integrations/index.md — Integrations hub page
- integrations/providers.md — AI provider setup (extracted)
- user-guide/features/overview.md — Features hub page
Broken link fixes:
- quickstart.md, faq.md: update context-length-detection anchors
- configuration.md: update checkpoints link
- overview.md: fix checkpoint link path
Docusaurus build verified clean (zero broken links/anchors).
The plugin system defined six lifecycle hooks but only pre_tool_call and
post_tool_call were invoked. This activates the remaining four so that
external plugins (e.g. memory systems) can hook into the conversation
loop without touching core code.
Hook semantics:
- on_session_start: fires once when a new session is created
- pre_llm_call: fires once per turn before the tool-calling loop;
plugins can return {"context": "..."} to inject into the ephemeral
system prompt (not cached, not persisted)
- post_llm_call: fires once per turn after the loop completes, with
user_message and assistant_response for sync/storage
- on_session_end: fires at the end of every run_conversation call
invoke_hook() now returns a list of non-None callback return values,
enabling pre_llm_call context injection while remaining backward
compatible (existing hooks that return None are unaffected).

* feat: config-gated /verbose command for messaging gateway
Add gateway_config_gate field to CommandDef, allowing cli_only commands
to be conditionally available in the gateway based on a config value.
- CommandDef gains gateway_config_gate: str | None — a config dotpath
that, when truthy, overrides cli_only for gateway surfaces
- /verbose uses gateway_config_gate='display.tool_progress_command'
- Default is off (cli_only behavior preserved)
- When enabled, /verbose cycles tool_progress mode (off/new/all/verbose)
in the gateway, saving to config.yaml — same cycle as the CLI
- Gateway helpers (help, telegram menus, slack mapping) dynamically
check config to include/exclude config-gated commands
- GATEWAY_KNOWN_COMMANDS always includes config-gated commands so
the gateway recognizes them and can respond appropriately
- Handles YAML 1.1 bool coercion (bare 'off' parses as False)
- 8 new tests for the config gate mechanism + gateway handler
* docs: document gateway_config_gate and /verbose messaging support
- AGENTS.md: add gateway_config_gate to CommandDef fields
- slash-commands.md: note /verbose can be enabled for messaging, update Notes
- configuration.md: add tool_progress_command to display section + usage note
- cli.md: cross-link to config docs for messaging enablement
- messaging/index.md: show tool_progress_command in config snippet
- plugins.md: add gateway_config_gate to register_command parameter table
The hooks page only documented gateway event hooks (HOOK.yaml system).
The plugins page listed plugin hooks (pre_tool_call, etc.) that weren't
referenced from the hooks page, which was confusing.
Changes:
- hooks.md: Add overview table showing both hook systems
- hooks.md: Add Plugin Hooks section with available hooks, callback
signatures, and example
- hooks.md: Add missing session:end gateway event (emitted but undocumented)
- hooks.md: Mark pre_llm_call, post_llm_call, on_session_start,
on_session_end as planned (defined in VALID_HOOKS but not yet invoked)
- hooks.md: Update info box to cross-reference plugin hooks
- hooks.md: Fix heading hierarchy (gateway content as subsections)
- plugins.md: Add cross-reference to hooks page for full details
- plugins.md: Mark planned hooks as (planned)
