Closes#26193
Adds ContextReferenceProvider ABC so plugins can register custom
@-prefixes (e.g. @issue:ENG-123) with autocomplete and expansion.
Plugin output flows through existing token-limit guards. Zero
breaking changes.
Additive plugin.yaml v2 fields (all optional; v1 manifests unchanged forever):
- manifest_version: manifest FILE-FORMAT version (absent = 1). Deliberately
split from api_version per the round-2 design correction. Newer-than-
supported versions load with a warning, unknown fields ignored.
- api_version: runtime plugin API generation the plugin targets (integer).
- requires_plugins: advisory inter-plugin deps ({id, version_range?}).
Missing dep = warn + still load (ctx.has_plugin() runtime probe added).
Load ORDER is dependency-respecting: graphlib topological sort, stable
alphabetical tiebreak; cycles warn and fall back to alphabetical.
- python_dependencies: declared pip requirements — VALIDATED AND SURFACED
ONLY (loader warning + install-time printout + doctor checks with a pip
install hint). Never auto-installed: the isolation design for the install
seam (#15220) is an explicitly deferred follow-up per the round-2 review.
- config_schema: JSON-schema-ish description of plugins.entries.<id>.settings
keys; validated at load, mismatches are actionable warnings naming the key
and expected type — never load failures.
- Formalized metadata: license, homepage, tags.
- Unknown manifest fields warn-don't-fail (debug-level for v1 manifests).
- hermes plugins doctor gains v2 checks: future manifest_version, invalid
api_version, dep declarations, unpinned/missing python_dependencies,
unknown config_schema types.
- Docs: manifest v2 reference table in the developer-guide plugins index,
including the explicit pip-seam isolation deferral and the note that
#64166 packs build on these fields.
- Tests: tests/hermes_cli/test_plugin_manifest_v2.py (19 tests) covering v1
regression, v2 parse, unknown-field warn, dep order, cycle fallback,
config_schema warnings, and the surfaced-not-installed pip seam.
Salvage of PR #64317 (@deaneeth) onto current main, implementing #64161:
observer-only on_stream_start / on_stream_delta / on_stream_end /
on_interim_message plugin hooks dispatched through a host-owned bounded
queue (one worker per callback) so plugin callbacks never run inline on
the token path. Reasoning deltas are opt-in via
plugins.stream_reasoning_deltas.
Unify the scattered per-plugin trust gates into one declared, diffable
capability model with an install/update-time consent flow. Consent +
audit over host API surfaces — explicitly NOT a sandbox.
New module hermes_cli/plugin_capabilities.py:
- Canonical CAPABILITY_REGISTRY mapping each capability id 1:1 to an
EXISTING enforcing gate (no capability minted without a surface):
tools.override -> allow_tool_override
llm.provider_override -> llm.allow_provider_override
llm.model_override -> llm.allow_model_override
llm.agent_id_override -> llm.allow_agent_id_override
llm.profile_override -> llm.allow_profile_override
llm.task_override -> llm.allow_task_override
- plugin_capability_granted(plugin_id, capability): canonical check —
granted set OR deprecated legacy allow_* key; fail closed on unknown
ids and any unreadable/corrupt consent state; emits checked_by audit
log lines on every decision.
- record_consent() persists plugins.entries.<id>.granted_capabilities +
capabilities_consent {hash, granted_at} and mirrors grants into the
legacy keys so existing enforcement sites keep working unchanged.
- capability_set_hash / pending_capabilities / declared_set_changed
power the update-time re-consent diff.
Wiring:
- plugin.yaml manifest field `capabilities:` parsed into
PluginManifest.capabilities (unknown ids dropped with a warning).
- hermes plugins install: consent screen (one Y/n) when the manifest
declares capabilities; non-interactive installs proceed with
capabilities ungranted (fail closed).
- hermes plugins update: when the new version declares capabilities the
granted set lacks (hash diff), the additions are surfaced and require
re-consent — an update can never silently widen access.
- hermes plugins enable: consent screen replaces the standalone
tool-override prompt for capability-declaring plugins.
- hermes plugins capabilities [<id>]: declared vs granted per plugin,
flags grants held via deprecated legacy keys.
- PluginContext.has_capability() probing API so plugins degrade
gracefully; _tool_override_allowed migrated to the canonical
plugin_capability_granted path (reference migration; legacy
allow_tool_override still honored).
Tests: tests/hermes_cli/test_plugin_capabilities.py (38 tests) —
declaration parsing, consent grant/persist, update re-consent on added
capability, fail-closed on missing/corrupt state, legacy-gate backward
compat, consent CLI flow (grant / decline / non-interactive).
Docs: user-guide plugins.md consent section (with explicit not-a-sandbox
warning) + developer-guide plugin authoring capability note.
Salvages the intent of PR #37976 (@coygeek — require renewed review
before plugin updates), scoped to capability diffs.
Part of #64182.
Builds on Paolo Antinori's #68431 salvage for #64176. Move plugin dispatch behind the profile-scoped runner authorization boundary, fail closed on malformed reaction identities, preserve observer registration across Telegram app rebuilds, and document the deliberately observer-only contract.

Response to teknium1's hermes-sweeper review (keep_open, salvageability=medium).
1. Post-auth gate. The group-99 catch-all fired gateway_platform_event before
the authorization boundary. Extract _is_source_authorized(source) from
_is_user_authorized_from_message and add _source_from_reaction_for_auth;
reactions whose actor the intake would reject no longer reach plugins.
Fails closed if source extraction raises, so a future non-reaction event
type cannot silently bypass auth before its own extraction is wired.
2. Shared registration. Extract _register_handlers(app) from connect() so the
gateway_platform_event observer (group 99) is re-registered alongside the
core handlers on any rebuild path.
3. Trim inert hook surface. Drop the three reserved gateway_* names from
VALID_HOOKS (keep only gateway_platform_event). The others land with their
real contracts and fire-sites when #64231 is finalized.
Tests: unauthorized/authorized/open reaction gating, fail-closed for a future
non-reaction event type, and _register_handlers re-registration.
Ran /simplify and /code-review (high) before pushing.
First slice of #64176's observer-hook half — a normalized-envelope inbound
event hook, replacing raw-SDK handler args with a stable contract (per #64176's
"normalized versioned envelopes only; raw SDK gated behind a capability" rule).
- VALID_HOOKS: register the four gateway_* names from #64176
(gateway_platform_event fires today; gateway_session_titled /
gateway_message_delivered / gateway_thread_created reserved pending #64176's
fire-sites).
- BasePlatformAdapter._fire_gateway_hook: reusable, has_hook-guarded,
per-call-isolated fire helper (the no-subscriber common case short-circuits).
- TelegramAdapter: a group-99 catch-all TypeHandler normalizes inbound updates
into gateway_platform_event envelopes. message_reaction -> {platform,
event_type:"reaction", payload{emojis, custom_emoji_ids, chat_id, message_id,
thread_id}} (custom-emoji reactions captured via custom_emoji_id; standard via
.emoji — no None in consumer-facing lists). Other update types return None
pending #64176's taxonomy (#64231). Normalization is wrapped so a malformed
update can't raise into PTB dispatch.
Observer-only — zero behavioral change to core dispatch. Supersedes the raw
inbound half of #62584 (telegram:update -> normalized gateway_platform_event).
Tests: VALID_HOOKS registration; _fire_gateway_hook routing/has_hook/isolation;
_normalize for standard, custom-emoji, and mixed reactions + non-reaction;
_on_platform_update firing + normalize-error isolation.
Ran code-review (high) + simplify before pushing.
Salvage the plugin-owned static prompt idea from PR #51589 into the constrained #64167 contract: stable IDs, deterministic placement, bounded fail-open rendering, and full-prompt resume recovery without new session columns.

Route plugin target parsing, validation, and host-driven delivery through PlatformEntry across CLI and cron while preserving the host-only send_message policy.
Wire an optional `task=<key>` kwarg through the PluginLlm facade so a
plugin can route an LLM call through an auxiliary model slot it
registered via `ctx.register_auxiliary_task`. Registration already
existed; this adds the missing consumption half. Closes#44673.
Sub-issue 08/14 of the plugin-interface expansion tracking issue #64182.
- New optional `task:` kwarg on complete/acomplete/complete_structured/
acomplete_structured. Unset or "auto" keeps today's main-model path
byte-for-byte (task=None reaches call_llm exactly as before), so no
prompt-cache or default-behavior change.
- A set task resolves provider/model through `auxiliary.<task>` via the
existing auxiliary_client path, identical to built-in aux tasks.
- Trust gate (per the round-2 design correction): a plugin may only pass
a key it registered itself; a built-in key additionally requires
`plugins.entries.<id>.llm.allow_task_override: true`. A foreign or
unknown key is rejected with a PluginLlmTrustError and a logged warning
naming the offending plugin and key -- fail loud, NOT a silent fallback
to auto (which would mask misconfiguration and could route to the main
model the user steered elsewhere).
- The plugin_llm audit dict and audit-log line gain a `task` field.
- register_auxiliary_task now stores the plugin's canonical id
(`key or name`, the same id ctx.llm is bound to) as the slot owner, so
the trust gate matches ownership even when a manifest sets a distinct
key. For the common no-key case this equals the name (unchanged).
Tests (tests/agent/test_plugin_llm_task_routing.py, 24): _check_task
resolution incl. own/foreign/unknown/built-in-gated keys and loud
rejection; end-to-end routing sync+async+structured; production-path
forwarding into call_llm/async_call_llm (covers the task=None->task line);
and ownership resolution against the real plugin registry incl. the
name/key reconciliation.

Address teknium1 review on #64189:
- Re-pull gate now delegates to each source's is_enabled(cfg) via the
registry contract, so a plugin source with custom activation logic is
honored (previously only secrets.<name>.enabled was checked).
- Add BUILTIN_SOURCE_NAMES to the registry so plugin-vs-bundled is a
single source of truth instead of a hard-coded set at the call site.
- Reconcile docs: rewrite the timing :::note to describe both the
post-discovery re-pull and the remaining import-time limitation, and
cross-link the first-process bootstrap section.
- Tests: real SecretSource subclasses, custom is_enabled activation
(positive + negative), is_enabled-raises skip, builtin-only no-op,
and a discovery-registration end-to-end re-pull check.
After plugins register SecretSource backends, reset the env-loader cache
and re-run load_hermes_dotenv when an enabled plugin secret source is
configured. Closes the first-process bootstrap gap where import-time env
load stale-outs plugin vaults (tommck / Community ask). Fail-open, no-op
without plugin sources.
Docs: first-process bootstrap timing on secret-source plugin guide.
Tests: unit coverage for noop / enabled re-pull / discover hook.

Cold CLI time-to-banner was ~1.8s (hermes) / ~2.8s (hermes -w). The banner
path was paying for work the session doesn't need before first input:
- aux availability probes built REAL OpenAI/httpx clients (openai import
~0.3s + SSL context) just to answer check_fns. New aux_probe_mode()
returns a cache-excluded stub; resolution policy unchanged.
- tools/mcp_tool imported the mcp SDK (~260ms, mcp.types pydantic model
construction) at module import even with zero MCP servers configured.
SDK import is now lazy behind _ensure_mcp_sdk(); _MCP_AVAILABLE is a
find_spec probe so every existing gate/test keeps its semantics.
- banner blocked 500ms on the update-check prefetch; now waits 50ms and
defers the warning line to a daemon thread (prints above the prompt).
- banner recomputed get_tool_definitions + skills scan + git state every
launch; now snapshotted to ~/.hermes/cache/banner_snapshot.json keyed on
(config.yaml, .env, checkout rev, toolsets) and replayed on warm launches
with a background refresh. Agent tool list is still computed fresh.
- _resolve_active_context_length probed the Nous portal /models (~200ms
network) per launch; the tool-search gate now prefers the on-disk
context cache when present.
- schema reconciliation re-executed SCHEMA_SQL in a scratch SQLite DB
(~85ms) per SessionDB(); the reference parse is now disk-memoized by
DDL hash (live-DB diffing still runs every startup).
- bundled-skills sync (~120-170ms rglob/hash) moved off the startup path
to a daemon thread; plugin discovery starts in the background and every
synchronous consumer joins via discover_plugins().
- hermes_cli.auth imported httpx eagerly (~30ms); now a lazy proxy that
test monkeypatching still reaches (setattr forwards to the real module).
- fast chat launch: unambiguous 'hermes'/'hermes chat' invocations skip
building all ~40 subcommand parsers (bails to full dispatch on anything
else, incl. container mode).
- -w path: git worktree add runs with checkout.workers=8 (0.6s→0.2s) and
overlaps HermesCLI construction; --skills preload runs in the background
and is folded in at agent init (finalize_preloaded_skills, same
fail-loud contract for fully-unknown skill lists); stale-worktree prune
moved off the banner path.
Warm results (PTY time-to-banner, 5-run): hermes 1.80s → 0.38-0.40s;
hermes -w -s hermes-agent-dev --yolo 2.82s → 0.57-0.69s.
PlatformEntry.check_fn served three contradictory roles: adapter-creation
gate, config auto-enablement gate, and status display. Plugins had to pick
one function for all three:
- Active installer as check_fn (discord/slack/telegram/matrix/dingtalk/
feishu): every status display could pip-install SDKs as a side effect
(the desktop 94% boot-loop class).
- Passive probe as check_fn (teams, wecom_callback): create_adapter()
returned None before connect() could lazy-install, so the SDK never
installed (#79812 deadlock; wecom_callback's platform.wecom_callback
LAZY_DEPS entry was dead code).
The split makes both call sites correct by construction:
- check_fn is now contractually PASSIVE (probe only, never installs).
- New optional PlatformEntry.ensure_deps_fn is the ACTIVE installer;
create_adapter() runs it exactly when check_fn is False — the platform
is enabled+configured and the gateway is about to connect it.
- Config enablement keeps a configured platform whose deps are missing
but installable; the install itself is deferred to create_adapter().
- Status surfaces (_platform_status, hermes status) read only the
passive probe and can never trigger pip.
Migrated all lazy-installable platform plugins to the split; platforms
with no optional deps (irc/ntfy/buzz/simplex/line/a2a/...) are unchanged
— no ensure_deps_fn means a False check_fn stays a hard block.
wecom_callback gains a working installer for the first time.
Builds on @xxxigm's #79812 (both commits cherry-picked with authorship
preserved), reworking the check_fn swap into the two-field split so the
Teams fix doesn't reintroduce install-on-status.
AST-driven pass over every Path.read_text()/write_text() without an
explicit encoding= across non-test code: 71 sites in 34 files
(skills_hub, hermes_cli/main+profiles+service_manager+container_boot,
mem0/hindsight/honcho plugins, achievements dashboard, release/CI
scripts, productivity+comfyui skill helpers, agent/*). Verified zero
positional-encoding collisions before insertion; per-file compile()
check after.
Adds a check-windows-footguns rule flagging bare single-line
read_text/write_text (multi-line forms stay covered by the AST guard
test from #38985). Together with the salvaged contributor commits this
retires the ~169-site bare file-I/O class (#37423's long tail).
Extend the pre_tool_call plugin hook return contract with a new directive:
{"action": "approve", "message": "why this needs human confirmation"}
Previously a pre_tool_call hook could only veto a tool call (action: block)
or allow it silently. It could not escalate to the existing human-approval
flow. This unlocks user-defined runtime approval rules on ANY tool (HTTP
writes, file writes to sensitive paths, email sends), enforced at runtime —
resolving #51221 as a pure plugin, with no core approval.py rule schema.
Mechanism:
- get_pre_tool_call_directive() returns (action, message) for block|approve;
get_pre_tool_call_block_message() kept as a block-only back-compat shim.
- resolve_pre_tool_block() is the single dispatch-site chokepoint: fetches
the directive and, for approve, invokes the human gate; fail-closed to a
block on denial, timeout, or gate exception. ALL FOUR tool-dispatch sites
now call it: tool_executor (concurrent + sequential), agent_runtime_helpers,
and model_tools.handle_function_call.
- request_tool_approval() escalates via the SAME machinery as Tier-2
dangerous commands: session/permanent allowlist, prompt_dangerous_approval
(CLI) / submit_pending (gateway), [o]nce/[s]ession/[a]lways/[d]eny,
timeout fail-closed, approvals.cron_mode for cron contexts.
Architecture: extracted the shared decision core into _run_approval_gate(),
called by BOTH check_dangerous_command() and request_tool_approval() so the
fail-closed / cron / gateway / yolo / persist policy lives in ONE place and
cannot drift. Fixed a latent divergence — the plugin path now honors --yolo.
Approval grain: [a]lways is keyed on tool_name + a hash of the reason (an
explicit plugin rule_key overrides), so distinct reasons on the same tool
persist independently instead of one 'always' blanketing the whole tool.
Non-interactive: cron honors approvals.cron_mode (parity with commands); any
other non-interactive non-gateway context fails CLOSED for the plugin path
(the command path keeps its historical fail-open default, unchanged).
No new config schema, no new env vars, no new hook events.
egilewski found the prior sink gate was transient: it only applied while
PluginManager executed register(ctx). A plugin could defer a direct
registry.register(..., override=True) to a post-load callback/thread, after
the scope was cleared, and still replace a built-in.
Make authorization durable by binding it to where the handler is DEFINED
(handler.__globals__['__name__']) rather than to call timing. At load, each
plugin's module namespace is mapped to its allow_tool_override opt-in in a
table that is never cleared. The sink resolves the handler's owning plugin
module and rejects an override from any plugin namespace without opt-in,
regardless of when or on which thread the call happens. Plugin namespaces
with no recorded policy are treated as not-opted-in (fail-closed). Built-in
and MCP handlers live outside the plugin namespace and are unaffected.
Adds a regression test for the delayed/post-load direct-registry override.
The opt-in gate lived only in PluginContext.register_tool, so a plugin
could bypass it by importing tools.registry and calling
registry.register(..., override=True) directly. Enforce the same gate at
the sink: during plugin load, the registry rejects an override from a
plugin without operator opt-in regardless of the path taken. Built-in and
MCP registrations (no active plugin scope) are unaffected.
Adds a regression test covering the direct-registry bypass.
The tool_override flag landed in v0.14.0 (#26759) so plugins can replace
a built-in tool with their own implementation. It works as advertised
but there is no trust gate, so any enabled third-party plugin can
silently override any built-in like shell_exec, write_file, or web_fetch
and exfiltrate everything the agent invokes through it. The only trace
is a DEBUG-level log line.
Compare with ctx.llm (#23194) which does gate the equivalent privilege
escalation: overriding the provider requires
plugins.entries.<id>.llm.allow_provider_override: true in config.yaml.
The policy shape exists, it just was not extended to tool overrides.
Fix:
* Add PluginToolOverrideError(PermissionError) for the gate failure.
* register_tool() now checks _tool_override_allowed(name) when
override=True. Bundled plugins (manifest.source == 'bundled') are
trusted by default. Every other source requires
plugins.entries.<plugin_id>.allow_tool_override: true in config.yaml.
* fail-closed: if config.yaml cannot be loaded for any reason,
_tool_override_allowed returns False. Same posture as
MSGraphWebhookAdapter.connect() in #22353.
Backwards compatibility:
* Bundled plugins: no change (source == 'bundled' short-circuits the
gate).
* Third-party plugins not using override: no change (gate is only
consulted when override=True).
* Third-party plugins using override: registration fails until the
operator opts in. The error message includes the exact config path
to add, so the fix is one config edit away for legitimate use cases.
Same migration path users went through for allow_provider_override
after #23194 landed.
Regression tests:
* tests/hermes_cli/test_plugins.py::test_register_tool_override_replaces_existing
and ::test_register_tool_override_on_new_name_is_noop_path were
written before the gate existed. Updated their test configs to
include allow_tool_override: true under
plugins.entries.<plugin_id>, mirroring how a legitimate operator
would now grant the privilege.
* New regression test ::test_register_tool_override_blocked_without_operator_opt_in
exercises both the PluginManager-catches-error path (built-in tool is
preserved, attacker plugin is skipped) and the direct-call path
(PluginToolOverrideError is raised with a message that names the
config key to set). Verified the test fails without this fix and
passes with it.
* All 73 tests in test_plugins.py continue to pass.
Add a `pre_verify` user/plugin/shell hook fired once per turn when the agent
edited code and is about to finish, after the existing verify-on-stop guard. A
hook can keep the agent going one more turn (run a check, defer it, tidy the
diff) by returning {"action":"continue","message":...} (the Claude-Code Stop
shape {"decision":"block","reason":...} is accepted too). Hooks receive coding,
attempt, final_response, and sorted changed_paths so they can self-scope and
self-throttle; the path is bounded by agent.max_verify_nudges and preserves
message-role alternation.
Hermes still ships its default coding guidance (agent.verify_guidance, on by
default), but it now rides the evidence-based verify-on-stop missing-evidence
nudge instead of a separate default pre_verify continuation, so it costs no
extra model turn of its own. Guidance reuses the shared utils.is_truthy_value
parser rather than a local copy.
The startup config/manifest reads used PyYAML's pure-Python SafeLoader,
which is ~8x slower than the libyaml-backed CSafeLoader C extension.
config.yaml is parsed several times during launch (cli config, raw
config, early interface/redaction bridge, logging config) and every
plugin manifest is parsed once — all on the slow path.
Add utils.fast_safe_load (CSafeLoader-preferring, pure-Python fallback,
true drop-in for safe_load) and route the hot startup parse sites
through it: hermes_cli/config.py (config + manifest reads),
hermes_cli/plugins.py (manifest parse), env_loader, cli.load_cli_config,
hermes_logging, and the two pre-config early YAML bridges in main.py.
Behavior is identical (same restricted safe tag set); only speed changes.
safe_load calls on the startup path drop from ~79 to ~0, cutting the
YAML parse cost from ~0.9s to ~0.15s under profiling.
Adds tests/test_fast_safe_load.py asserting equivalence with safe_load
across input shapes, empty-doc falsiness, C-loader preference, and that
python/object tags are still rejected (safe, not full loader).
Bundled platform plugins (telegram, discord, feishu, teams, ...) were
eagerly imported at plugin-discovery time on every `hermes` invocation,
including plain `hermes chat` which never touches a gateway platform.
Their modules import heavy platform SDKs at module level (lark_oapi,
microsoft_teams, discord.py, slack_bolt, ...) — feishu alone pulled in
lark_oapi (~2.6s), teams pulled microsoft_teams (~1.9s).
Discovery now registers a cheap deferred loader per platform in the
platform_registry; the adapter module is imported only when the gateway
/ cron / setup / send_message path actually asks for that platform.
is_registered() and the iterate-all accessors stay correct (deferred
counts as registered; plugin_entries()/all_entries() materialize all
deferred loaders, since those paths genuinely need every adapter).
Cold start: ~4.4s -> ~2.45s to banner. discover_and_load: 2.0s -> 0.3s
(warm), and the heavy SDKs are no longer imported at all in CLI mode.
Every shipped platform remains available out of the box — it just loads
on first use.
Plugins could observe session/tool/approval lifecycle but had no way to
observe kanban task transitions. Adds three observer hooks fired by the
board's claim/complete/block transitions:
- kanban_task_claimed (dispatcher process, before worker spawn)
- kanban_task_completed (worker process, carries summary)
- kanban_task_blocked (worker process, carries reason)
Each fires AFTER the DB write txn commits, so a plugin observes durable
state and a slow/hanging callback can never hold the SQLite write lock.
All firing is best-effort: a raising hook is logged and swallowed and
never breaks a board transition. profile_name is resolved from
HERMES_HOME so dispatcher- and worker-side hooks carry the right profile.
Requested by @Smithangshu on Discord.
Plugins previously had no way to read the active profile name from the
PluginContext. The workaround in the wild — reaching into
ctx._manager._cli_ref — only works in an interactive CLI session;
_cli_ref is None in the gateway and in kanban-spawned worker sessions
(hermes -p <profile> chat -q ...), so the workaround breaks exactly
where multi-profile awareness matters most.
ctx.profile_name wraps hermes_cli.profiles.get_active_profile_name(),
which derives the name from HERMES_HOME and therefore works in every
execution context with zero dependency on _cli_ref.
* feat(cli): add --safe-mode troubleshooting flag
Inspired by Claude Code v2.1.169 (June 2026): run Hermes with all
customizations disabled to isolate setup problems from product bugs.
--safe-mode implies --ignore-user-config and --ignore-rules, and
additionally skips plugin discovery (hermes_cli/plugins.py) and MCP
server loading (tools/mcp_tool.py) via the internal HERMES_SAFE_MODE
env bridge.
* fix(desktop): keep composer usable during reconnect
