Live Desktop E2E (real Electron, worktree backend, demo plugin on old paths) found the modal never fired:
compat_report() was only called from the CLI banner / doctor / update / plugins-compat surfaces, none of
which run inside the Desktop's `serve` backend, so .plugin-compat-report.json was never written.
PluginManager.discover_and_load now refreshes the report from the manifests it just discovered (fail-open).
E2E after the fix, all five acceptance steps green on the real seat: report written and names the plugin;
native dialog 'Plugins need an update' with plugin, date, and `hermes plugins compat`; OK persists the
dismissal; relaunch with the same userData shows nothing and logs no 'compat notice shown'; fixing the
plugin's imports deletes the report and shows nothing.
Every PLUGIN-COMPAT __getattr__ now calls hermes_cli.plugin_compat.warn_once(facade, name, target) before
resolving, emitting a HermesPluginCompatWarning (FutureWarning) once per process per name: old path, new
path, removal target. Importing a facade for its live API stays silent; only resolving a moved name warns.
COMPAT_MANIFEST.md documents the warning and how to silence it during migration.
Verified the runtime never routes through a pointer: every entry point (run_agent, cli, hermes_cli.main,
gateway.run, tui_gateway.server, web_server, model_tools + tool discovery, hermes_state, cron.scheduler,
browser_tool, mcp_tool, kanban, auth) imports clean and `hermes doctor` runs end to end with the warning
promoted to an error.
Also restores the check_compat_pointers CI step to .github/workflows/lint.yml, which a0be177aac dropped
when the compat layer was regenerated (the lint script itself was present; the workflow step was not).
hermes_cli/plugin_compat.py, tests/test_plugin_compat_warning.py and the two-line insert per facade are
part of the compat layer and go away with it.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
No runtime consumer read the proxy (terminal_tool/environments call is_interrupted()/set_interrupt()
directly); its only users were tests patching tools.interrupt._interrupt_event, which had no effect on
the code under test. tools/terminal_tool.py's own re-export of the name is owned by another worker.
tools/approval.py no longer re-exports sibling names (approval_context/prompt/floors/detection/
human_wait/smart/gateway_wait); it imports only what it uses. Siblings reference sibling-defined
names directly (module-attribute reads on tools.approval_context so patching the defining module
still works); only facade-owned state (_lock, _gateway_queues, _permanent_approved, _denied,
_denial_breaker_addendum, _gateway_notify_cb) is still read back through tools.approval.
approval_detection calls its own _command_detection_variants instead of late-binding through the facade.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
hermes_cli/plugins.py (7193 -> 4961):
- _register_scoped_provider: one body for the 8 scope-keyed register_*_provider methods;
_track_callback/_track_mapping_entry unify manager-mapping lease tracking (4 sites);
_track_scoped_registration for the ownership ledger. Public method names, signatures,
return values and warning strings unchanged.
- Manifest v2 type checks table-driven (_manifest_field_of_type); _unload_scoped split into
_unload_target_keys + _reset_after_unload_all; _gate_manifest/_record_placeholder out of
_discover_and_load_inner; _track_tool_override_policy/_attribute_registrations out of
_load_plugin_scoped; bounded hook worker lifted into _run_hook_callback_bounded;
prompt-section rendering extracted; resolve_pre_tool_block delegates to
_dispatch_pre_tool_call_hooks; _evict_modules (3 sites); _remove_name_if_unowned and
_nowait_plugin_set unify unowned-name cleanup and *_nowait probes.
- Dead (zero references outside their own test): unload_plugins, has_portable_mcp_servers,
_classify_entrypoint_kind, _reset_event_bus, get_plugin_subscriptions,
get_telegram_handler_factories, pass-through _restore_* helpers; _env_enabled is now an alias
of utils.env_var_enabled (plugins/memory still imports it).
- Docstrings/comments compacted; contract sentences and rationale kept (multi-profile ledger
keying, persistent auth-provider registration, capability declaration is not a grant).
re_register_config_hooks() cleared the entire process-global idempotence
set on every force-reload, so a profile-local plugin force-reload dropped
another live profile's ledger key without touching its still-registered
callback — the next registration call for that profile then appended a
duplicate. Scope the clear to the reloading profile's own home, and give
outbound webhooks the same force-reload restoration shell hooks already
had, since unload() wipes both from the shared _hooks dict.
New commands and plugins declare argument_mode and desktop availability
on CommandDef / register_command. commands.catalog ships that map so
desktop does not need a second command list.
ctx.register_platform_handler(platform, factory) — the generic surface for
plugins to wire native handlers into any platform adapter at connect()
time. Factories receive (native, adapter): the platform's client/app
object (PTB Application, discord.py Bot, slack_bolt AsyncApp, Teams App,
DingTalkStreamClient, aiohttp web.Application) or None for adapters with
no separate native object.
- BasePlatformAdapter._wire_plugin_handlers(native): shared, isolated
invocation helper — a raising plugin cannot block a platform connect.
- All 27 connectable adapters call it: telegram/slack/teams/line/
api_server/msgraph_webhook wire before their dispatch tables freeze;
the rest hook at connect success.
- register_telegram_handler and get_telegram_handler_factories retained
as thin back-compat aliases over the telegram bucket.
- Source-invariant test guarantees every adapter with connect() keeps
calling the hook.
Mirrors the Slack precedent (register_slack_action_handler): plugins queue
a factory at register() time; the Telegram adapter invokes each factory
with (application, adapter) at connect() time, before the core handlers
register, so pattern-scoped plugin handlers take precedence for their own
updates while everything else falls through unchanged. Factories are
isolated — a raising plugin cannot prevent Telegram from connecting.
Unblocks standalone plugins that need PTB update types the core adapter
doesn't route (Telegram Business API secretary bots, custom callback
prefixes, chat-member events) without touching core files.
Allowlist hot-path hooks for abandon-on-timeout, keep subagent_stop on the caller thread, suppress re-fires of hung callbacks, and block tools when pre_tool_call times out.
web_extract stopped using an auxiliary LLM long ago (deterministic
truncate-and-store), but browser snapshots still routed oversized
accessibility trees through the auxiliary web_extract model, keeping a
dead-looking aux slot alive across every config/picker surface.
- tools/browser_tool.py: remove _extract_relevant_content and
_get_extraction_model; oversized snapshots always truncate at line
boundaries, store the full tree to cache/web, and append a read_file
pointer (element refs beyond the cut live in the file)
- tools/browser_camofox.py: same — no LLM path
- Remove auxiliary.web_extract slot: config_defaults (removal note, same
pattern as session_search/PR #27590), cli.py defaults + env bridge,
gateway/run.py bridged keys, hermes config display, hermes model picker,
dashboard REST slots, desktop + web AUX_TASKS, i18n labels (en/zh/
zh-hant/ja/ar)
- Docs: env-vars, configuration, fallback-providers, browser + zh-Hans
mirrors (web-search zh-Hans was stale on the old LLM pipeline — synced
to truncate-and-store truth)
- Tests updated: aux bridge uses approval slot, browser tests assert the
LLM path is gone and stored files are secret-redacted
Follow-up to the #91701 salvage: persistent registrations survive a routine
unload-all, but must not outlive their plugin.
- Targeted unload (plugin disable/uninstall) now gathers persistent rows
from the ownership ledger and disposes them.
- Unload-all parks live persistent handles in _persistent_carryover;
discover_and_load(force=True) evicts the ones whose plugin did not
re-register the same (kind, key) — superseded handles are dropped
without disposal so a same-object re-registration stays live.
The dashboard auth registry is process-global, but a bundled auth provider
was registered under the per-home plugin manager's scope and enrolled in that
manager's reverse-order teardown. A per-home manager is unloaded routinely
(profile-scoped dashboard activity, forced re-discovery), and that teardown
disposed the registration — emptying the auth registry for the whole process
and permanently disabling sign-in until restart.
Register dashboard-auth providers in the process-global slot as persistent
host-owned registrations kept out of per-home manager teardown, so a routine
unload can no longer disable authentication process-wide. Registration upserts,
so a forced re-discovery (e.g. a password change) still rotates the provider in
place. The test-only manager reset now clears the auth registry too, since
persistent registrations deliberately survive unload.
Fixes#91701
Follow-up to the #28953 salvage:
- Extract _resolve_block_from_details() so resolve_pre_tool_block and
_dispatch_pre_tool_call_hooks share ONE fail-closed approval-gate
implementation. This also gives the new dispatcher the observability
context wrapping around request_tool_approval that the original PR's
inlined copy lacked.
- Update sibling tests that patched resolve_pre_tool_block at the three
migrated dispatch sites to patch _dispatch_pre_tool_call_hooks with the
(block_message, modified_args) tuple contract.
Verified: 448 targeted tests green; E2E with a real shell hook in an
isolated HERMES_HOME rewrote a live write_file call (path + content)
through handle_function_call, with block and negative paths intact.
Adds a `modify` response type to pre_tool_call hooks so a hook can
transform tool arguments before the tool executes, instead of repairing
results afterwards via post_tool_call.
- hermes_cli/plugins.py: _dispatch_pre_tool_call_hooks() fires hooks once
and returns (block_message, modified_args); modify directives
shallow-merge into an accumulated dict built from the original args.
- agent/shell_hooks.py: _parse_response() accepts both the canonical
{"action": "modify", "args": {...}} and Claude Code-compatible
{"decision": "modify", "tool_input": {...}} wire formats.
- model_tools.py, agent/tool_executor.py, agent/agent_runtime_helpers.py:
dispatch sites migrated; modified args applied before execution.
- Docs + 10 new tests (merge semantics, precedence, block interplay).
Salvaged from PR #28953. Best fix for #18988.
Rebased onto current main. `hermes_cli/plugins.py` grew 103KB -> 265KB
across 49 commits since the original branch point, and the attribution
mechanism this change hooks into was replaced along the way: the
`_tools_before` / `_plugin_tool_names` snapshot diff is now a
registration ledger sliced from `registration_start`, and `_plugin_id`
is `plugin_key`.
Re-anchored accordingly:
- Discovery-time pre-registration, module reuse, and the `provides_tools`
opt-in are unchanged.
- Attribution credits `_predeclared_tools` ahead of the ledger slice,
since those tools registered before `registration_start` and the slice
cannot see them.
- A failed materialization no longer carries attribution across. The
failure path now sweeps the whole ownership ledger for the plugin key,
not just the `registration_start:` slice, so the pre-registered tools
are disposed along with the adapter. Attribution and the registry now
agree at zero instead of reporting tools the process is not serving.

Builds on the three salvaged commits: adds the sources and integration points
they leave out, so a pip-installed memory provider is not a second-class
citizen next to a directory install.
Discovery
- Project-local providers (./.hermes/plugins/<name>/), gated on
HERMES_ENABLE_PROJECT_PLUGINS exactly as PluginManager gates its own project
scan. Completes the four sources CONTRIBUTING.md and AGENTS.md already
promised; memory was the only discovery system missing two of them.
- find_provider_dir() now resolves a package entry point to its directory.
This is load-bearing: config_schema.py (the dashboard panel) and cli.py (the
`hermes <provider>` subcommands) are read from disk rather than imported, so
without a directory a pip-installed provider silently lost both.
- list_memory_provider_names() includes entry-point providers, so they appear
in the dashboard's memory.provider dropdown.
Resolution stays import-free. hermes_cli.plugins.resolve_module_origin() is
extracted from _resolve_module_source() (added by the salvaged #76567) and
shared, so discovery walks a module's file layout instead of importing it.
find_provider_dir() is called from the dashboard and from argparse setup, long
before the operator has chosen a provider — importing every installed candidate
would execute third-party code on the strength of a package being present.
A test asserts the resolution leaves no side effects and no sys.modules entry.
Registration
- PluginContext gains register_memory_provider(). Memory was the only provider
category without one; context engine, image gen, video gen, web search,
browser, TTS, transcription, secret source, dashboard auth and platform all
have one.
- _ProviderCollector delegates unknown register_* calls to a real
PluginContext instead of carrying three hand-written no-ops. It silently
dropped register_tool/register_hook, and had no register_auxiliary_task at
all — despite PluginContext.register_auxiliary_task documenting a memory
provider (hindsight's pre-retain dedup) as its worked example. It can no
longer drift behind PluginContext.
- A raise after register_memory_provider() no longer costs the provider. The
loader caught it into a debug log, discarded the registered instance, and
fell through to "instantiate any MemoryProvider subclass" — returning a
different, unconfigured provider. A silent downgrade that looked like
success, and the exact outcome of calling register_auxiliary_task.
Activation is unchanged: still gated on memory.provider naming the plugin, and
covered by a test so the real PluginContext cannot start requiring
plugins.enabled — that would break every existing user-installed provider.
Verified end to end against a real third-party provider (kainappsinc/elephant)
installed by pip alone, with no directory copy: it appears in the dropdown,
resolves its directory, loads with its tools, and renders its dashboard panel.
Closes#40101.
Documents and tests the routing contract the sweeper review asked about:
classification records the manifest but does not activate anything.
- model-provider test now exercises providers.get_provider_profile() against
the pip-only name (None today — providers discovery is directory-based)
and asserts the module never leaks into sys.modules via that path.
- new test for the mnemosyne shape: a pip entry point duplicating a
same-name directory provider. The pip copy is classified exclusive and
never imported; the directory copy still activates through
plugins.memory discovery, exactly once.
- _classify_entrypoint_kind docstring now states the activation contract
explicitly: pip-only providers were equally unactivatable pre-change
(both destination systems are directory-only; the
hermes_agent.memory_providers entry-point group has no consumers), so
classification only removes the wasted import. Entry-point activation
is tracked upstream (#40644 for memory); this change is its
prerequisite, preventing double import once it lands.
find_spec() on a dotted module name imports the parent package first,
executing its __init__.py — which is exactly where a provider's heavy
imports typically live (fastembed -> onnxruntime and friends). The
previous classifier only preserved the no-import property for
top-level entry points.
_resolve_module_source() now resolves only the top-level name with
find_spec() (import-free for top-level names) and walks the remaining
dotted segments through submodule_search_locations by hand, mirroring
PathFinder's file conventions (part.py module / part/__init__.py
package). Namespace packages, zipped modules, extension modules, and
anything else unexpected fall back to standalone (the safe default).
.pyc origins map back to source via source_from_cache.
Regression: a dotted entry point whose parent __init__.py writes an
execution marker and imports the child — asserts the parent never
executed and neither module enters sys.modules during classification.
Fails against the previous implementation (marker written), passes now.
