Copilot CLI v1.0.79 added an autoUpdate marketplace setting that refreshes
plugins at session start. Hermes adaptation:
- hermes plugins update --all: sweep every git-installed plugin; pinned
plugins and non-git dirs are skipped with a note instead of aborting.
- hermes plugins autoupdate <name> [on|off]: per-plugin opt-in flag stored
in the install metadata sidecar (pinned/non-git plugins are rejected).
- Startup sweep: opted-in plugins are git-pulled on the background
plugin-discovery thread AFTER discovery completes, throttled to once per
24h via a stamp file. The running session keeps the code it already
imported; updates take effect next session (stale bytecode cleared),
so the live registry and prompt cache are never touched.
- Non-interactive updates leave newly declared capabilities ungranted
(fail closed), same as the existing update path.
- Docs + 20 new tests (real-git E2E for pull/revision/bytecode/throttle).
Adds hermes-pack.yaml: a single YAML file pinning a set of plugins to
exact 40-char commit SHAs with optional non-secret plugins.entries
config seeds and a declared (not yet installed) skills list.
CLI:
- hermes plugins pack install <path|https-url> [--force]: mandatory
review screen (plugins + refs + declared capabilities), one summary
confirmation, then fan-out through the existing pinned install path.
Per-plugin capability consent rides the standard #64228 flow — a pack
never bulk-grants. Partial failures reported per plugin; non-zero
exit when any fail. Interactive only (no --yes in v1).
- hermes plugins pack export [--enabled-only] [--name]: pack YAML on
stdout from install metadata (repo + exact SHA); local-only plugins
become warning comments; secrets/capability grants stripped.
- hermes plugins pack show <path|url>: dry-run view.
Supply chain: refs must be exact 40-char SHAs (tags/branches rejected
naming the entry, same rule as the community index); config seeds
reject secret-shaped, capability, and allow_* keys; bare names resolve
through the community index; https-only URL fetch with size cap.
Tests: tests/hermes_cli/test_plugin_packs.py (36) — parse/validate,
SHA enforcement, mocked install fan-out, consent-per-plugin assertion,
export round-trip + sanitization, partial-failure exit code, parser
wiring. No live network.
Docs: user-guide plugins.md packs section (notes packs build on the
manifest v2 fields per #64165) + cli-commands.md rows.
Closes#64166
Give plugins a first-class, namespaced pub/sub event bus so plugin↔plugin
interaction is a declared, testable contract instead of ad-hoc imports.
Closes#64164 (sub-issue 03/14 of the plugin-interface expansion epic #64182).
Additive-only: when no plugin calls emit/subscribe, behavior is unchanged.
Interface (on PluginContext):
- `ctx.emit(event, payload=None) -> int` publishes to subscribers and returns
the count invoked. The namespace is FORCED to the plugin's own registry key
(`manifest.key or manifest.name`): pass only the bare event name, delivered
as `<key>:<event>`. Fail-closed — any name containing `:` (a `hermes:`
reserved-core prefix, a foreign `other:` namespace, or an own-colon'd name)
is rejected with a ValueError + logged warning naming the plugin.
- `ctx.subscribe(full_event, callback)` registers an ordered listener for a
fully-qualified `<plugin>:<event>`. Subscribing is unrestricted (any plugin
may listen to any published event); only emitting is namespace-gated.
Delivery mirrors invoke_hook: registration-order iteration, per-callback
try/except isolation (one raising subscriber never breaks delivery to the
rest), payload passed as `cb(**payload)`. A per-thread depth counter caps
re-entrant emits at 8 — mutually-emitting plugins terminate cleanly with one
logged warning, never an infinite loop or RecursionError.
Discoverability: optional advisory `emits:`/`listens:` manifest fields (no
manifest-v2 dependency; not enforced) are parsed and surfaced by a new
`hermes plugins show <name>` (alias `info`) command. `get_plugin_subscriptions()`
module accessor mirrors `get_plugin_auxiliary_tasks()`.
Tests (tests/hermes_cli/test_plugin_event_bus.py, 22): two-plugin delivery +
listener count; forced namespace (delivered as `b:ping`); spoof rejection
(parametrized `hermes:x` / foreign / own-colon'd / `:x` / `x:` / empty) with
no delivery; name-fallback when key empty; per-callback isolation; recursion
cap termination + warning; manifest emits/listens parsed (present/absent/from
yaml); module accessor; `plugins show` output. `pytest test_plugin_event_bus.py
test_plugin_auxiliary_tasks.py` → 37 passed. I independently re-verified the
namespace rejection and recursion-cap termination outside the test suite.
Note: the reserved-name gate rejects any `:`-containing input rather than a
bare-name denylist — a bare `core_event` is allowed and delivered under the
plugin's own namespace. Say the word if a reserved bare-name list is wanted.

Static machine-readable community plugin index with fuzzy search and
index-resolved installs, mirroring the Skills Hub catalog pattern
(fetch → HERMES_HOME/cache with 24h TTL → bundled seed fallback).
- hermes_cli/plugin_index.py: index fetch/cache/seed chain, fuzzy
search (name/description/tags/author + typo tolerance), capability
filter, bare-name resolution. Canonical URL overridable via
plugins.index_url config key.
- hermes_cli/data/plugin_index.json: bundled seed (offline fallback +
format reference) with 5 real ecosystem plugins, each pinned to an
exact commit SHA.
- hermes plugins search [term] [--json] [--capability] [--refresh]:
Rich table or JSON output, offline-safe, with an explicit
'indexed ≠ audited' footer.
- hermes plugins install <name>: bare names (no slash, no URL scheme)
resolve through the index to owner/repo[/subdir] @ pinned ref and
hand off to the existing install path (ref wired through the #82029
exact-ref support). Ambiguous names list candidates and exit;
explicit owner/repo and Git URL installs are untouched, and an
explicit --ref always beats the index pin.
- Docs: discovery section in user-guide plugins.md (format, submission
workflow via PR to hermes-plugin-index, security framing) and
reference/cli-commands.md rows.
- Tests: tests/hermes_cli/test_plugin_index_search.py (38 tests, no
live network) covering parsing, search, remote→cache→seed fallback,
TTL, install resolution/ambiguity/passthrough, and --json output.
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 memosr's sink-level opt-in gate (#29249). Enabling a
non-bundled plugin now surfaces the privileged allow_tool_override
decision at `hermes plugins enable` time instead of leaving the
operator to discover the config key after a runtime rejection.
- `hermes plugins enable <name>` prompts for non-bundled plugins:
'Allow this plugin to replace built-in tools?' Default is deny
(blank Enter / non-interactive stdin / EOF all fail closed).
- --allow-tool-override / --no-allow-tool-override flags for
non-interactive and scripted use (and a future desktop checkbox).
- Bundled plugins are trusted: never prompted, no entry written.
- Writes plugins.entries.<key>.allow_tool_override, the same key the
sink gate reads (manifest.key == discovery key), so consent and
enforcement compose end to end.
Subcommands whose handler was a closure defined inside main() — memory, acp,
tools, insights, skills, pairing, plugins, mcp, claw — have their handler
promoted to a top-level function and their parser block extracted into
hermes_cli/subcommands/<name>.py (build_<name>_parser, injected handler).
These 9 had zero closure-over-main-locals, so promotion is a pure relocation.
acp/mcp parser blocks use the shared add_accept_hooks_flag helper.
main() 1798 -> 954 LOC (71% below the 3297 Phase-2 starting point);
add_parser calls in main.py 89 -> 28.
Deferred: sessions, computer-use, secrets handlers reference <name>_parser
(for a no-subcommand print_help fallback) — left in place to avoid the
_self_parser indirection; minority, low value.
Behavior-neutral: all 9 subcommands' --help (incl nested subactions) byte-
identical to pre-extraction (diff-verified). tests/hermes_cli/ 6519 passed /
0 failed; new test_subcommands_followup.py covers the 9 builders.
