The LINE adapter classified every non-text inbound message as
`MessageType.IMAGE`, which doesn't exist on the enum — so any image,
video, audio, file, sticker, or location message raised AttributeError
the moment it was constructed.
Beyond fixing the crash, every non-text message was being collapsed onto
a single type. The gateway routes on MessageType (voice → STT, files →
document handling, etc.), so misclassification silently mishandled media.
Replace the inline ternary with a `_LINE_MESSAGE_TYPES` lookup that maps
each LINE webhook type to its proper enum member (audio → VOICE to match
how Telegram/WhatsApp treat voice notes), falling back to TEXT for
unknown types. Adds regression tests covering the mapping and the old
AttributeError.

* Revert "fix(gateway): anchor Google Chat OAuth client secret to default Hermes root"
This reverts commit fff0561441.
* Revert "fix(cli): honor global-root active_provider fallback for named profiles"
This reverts commit 3858cf4307.
* docs(google_chat): describe OAuth client secret as profile-scoped, not host-wide
The setup docs, oauth docstring, and the adapter's 'no credentials'
error message all described the Google Chat OAuth client secret as
host-wide shared infrastructure. That contradicts profile isolation:
profiles are separate auth boundaries, so two profiles can point at
different Google OAuth apps / accounts. Reword all three to say the
secret is profile-scoped and each profile registers its own.
All Discord interactive views (ExecApprovalView, SlashConfirmView,
UpdatePromptView, ModelPickerView, ClarifyChoiceView) now edit their
message when the view times out, disabling buttons and updating the
embed to show a 'Prompt expired' footer. Previously, timed-out buttons
remained visually clickable in the UI, causing Discord's generic
'Interaction failed' error when clicked.
Fixes#38022
Do not treat lack of application-level SimpleX events as a stale WebSocket. The websockets client already uses protocol ping/pong for connection liveness, so quiet but healthy connections should not be closed by the health monitor.
Adds tests for the echo-loop fix (outgoing X-Tags header, inbound skip
on tagged events, genuine tags pass through) and extends the tag to the
out-of-process _standalone_send() path so cron / send_message deliveries
to a self-subscribed topic are also skipped. Maps both contributors in
release.py AUTHOR_MAP.

When publish_topic equals the subscribe topic, the agent's own replies
are echoed back by ntfy as incoming messages, creating an infinite
reply spiral.
Fix: tag outgoing messages with X-Tags: hermes-agent header, and skip
incoming messages that carry this tag. This is zero-config — works
automatically regardless of topic configuration.

Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
When auto-threading kicked in, the broadened backfill gate ran on the
freshly-created thread — but the thread has no prior context to fetch,
and the parent-channel reference passed to _fetch_channel_context would
have leaked unrelated context (see #31467).
Skip backfill when auto_threaded_channel is set. Also teach the
_FakeTextChannel / _FakeThreadChannel test doubles to expose a no-op
history() async generator so the broadened gate doesn't trip
AttributeError → discord.Forbidden (MagicMock) → TypeError in the
existing auto-thread tests. Add a regression test that asserts
auto-threaded messages do not trigger backfill.
Drop the _needed_mention local variable now that it has only one use,
inline its expression as _has_mention_gap, and add a comment explaining
the three backfill cases (mention-gated channel, thread, DM skip).
Behaviorally identical to the prior commit; cleanup only.

Discord threads where the bot has already participated bypass mention gating by default, but the backfill check was still tied to the mention-needed condition. That meant follow-up thread messages could trigger a response without providing recent thread history to the session.
Run history backfill for thread messages whenever backfill is enabled, while keeping DMs skipped and channel mention backfill behavior unchanged. Add a regression test for a known thread follow-up without an explicit mention.

* fix(plugins/discord): correct install_hint extra to [messaging]
The Discord platform registered install_hint pointing at
'hermes-agent[discord]', but pyproject.toml has no [discord] extra —
the deps live in [messaging] alongside Telegram and Slack. Users hitting
"Platform 'Discord' requirements not met" were directed at a pip command
that installs nothing.
* feat(nix): add #messaging and #full package variants
Make Discord/Telegram/Slack work out of the box for `nix profile install`
users. Messaging deps were dropped from [all] on 2026-05-12 in favor of
lazy-install, but lazy-install can't write to the read-only /nix/store —
users hit "No adapter available for discord" with no actionable guidance.
- #messaging: pre-built with discord.py/telegram/slack (+33 MB venv)
- #full: all 18 platform-portable extras + matrix on Linux only
(python-olm lacks Darwin PyPI wheels) (+738 MB venv)
Also adds a `messaging-variant` flake check that verifies `import discord`
succeeds in the sealed venv — regression guard for the lazy-install
migration.
Docs updated: Quick Start callout, extraDependencyGroups rewrite with
messaging as primary example + full extras table, troubleshooting row,
cheatsheet row.
Closure size deltas (measured x86_64-linux):
default 1792 MB pkg / 512 MB venv
messaging 1826 MB pkg / 546 MB venv (+33 MB)
full 2530 MB pkg / 1250 MB venv (+738 MB)
* chore(nix): trim variant comments + alphabetize full extras
Drop the date-stamped changelog from messaging-variant's comment and the
"+33 MB / +704 MB" numbers from the variant defs — those drift and belong
in the PR description, not source. Alphabetize the 18-extra list in #full
so future additions produce clean one-line diffs.
No semantic change. messaging-variant check still passes.
Extend PR #31716 to plugin setup paths that were also using bare
getpass.getpass(): hindsight (4 sites), honcho, simplex, line. Same
mechanical swap onto hermes_cli.secret_prompt.masked_secret_prompt.
Second migration of an existing built-in platform adapter after Discord
(PR #30591) — follows the same shape established by IRC / Teams / LINE /
Google Chat / SimpleX and the playbook in
`references/platform-plugin-migration.md`. Advances the umbrella refactor
in #3823.
Matches Discord's parity bar — adapter under `plugins/platforms/mattermost/`
with the standard `__init__.py` / `adapter.py` / `plugin.yaml` shell,
`register(ctx)` entry point, **no back-compat shim** at the old import
path, and full parity for all five hooks Discord uses plus the
`apply_yaml_config_fn` hook (mattermost is the second consumer of #25443
after Discord):
* `standalone_sender_fn` — out-of-process cron delivery via Mattermost
REST API. Picks up the thread_id + media_files capabilities the
legacy `_send_mattermost` lacked (parity with Discord's `_standalone_send`).
* `setup_fn` — interactive `hermes setup gateway` wizard.
* `apply_yaml_config_fn` — translates `config.yaml` `mattermost:` keys
(`require_mention`, `free_response_channels`, `allowed_channels`) into
`MATTERMOST_*` env vars (replaces the hardcoded block in
`gateway/config.py`).
* `is_connected` — declares connection state from `MATTERMOST_TOKEN` +
`MATTERMOST_URL`.
* `check_fn` — verifies aiohttp is installed and both required env vars
are set.
* plus `allowed_users_env`, `allow_all_env`, `cron_deliver_env_var`,
`max_message_length` (4000 — Mattermost practical limit), `emoji`,
`required_env`, `install_hint`.
Files
-----
* `gateway/platforms/mattermost.py` (873 LOC) →
`plugins/platforms/mattermost/adapter.py` (git rename, R071) +
appended `register()` block, hook helpers, and `_standalone_send`
with media upload + thread_id support.
* New `plugins/platforms/mattermost/{__init__.py, plugin.yaml}` with
`requires_env` / `optional_env` declarations covering MATTERMOST_URL,
MATTERMOST_TOKEN, MATTERMOST_ALLOWED_USERS, MATTERMOST_ALLOW_ALL_USERS,
MATTERMOST_HOME_CHANNEL, MATTERMOST_REPLY_MODE,
MATTERMOST_REQUIRE_MENTION, MATTERMOST_FREE_RESPONSE_CHANNELS,
MATTERMOST_ALLOWED_CHANNELS.
* `gateway/config.py`: delete 17-LOC `mattermost_cfg` YAML→env bridge
(moved into plugin's `_apply_yaml_config`).
* `gateway/run.py::_create_adapter`: delete `Platform.MATTERMOST elif` —
replaced by the existing generic plugin-registry-first dispatch.
* `tools/send_message_tool.py`: delete `_send_mattermost` (22 LOC) +
`Platform.MATTERMOST elif` in `_send_to_platform` — the `else` branch
already routes plugin platforms through `_send_via_adapter`, which
hits the registry's `standalone_sender_fn`.
* `hermes_cli/setup.py`: delete `_setup_mattermost` (44 LOC) — replaced
by the plugin's `interactive_setup`.
* `hermes_cli/gateway.py`: delete `_PLATFORMS["mattermost"]` dict entry
(3 LOC) — plugin's `setup_fn` is dispatched via the plugin path in
`_configure_platform`.
* Consumer rewrite: 5 test files (test_mattermost.py,
test_media_download_retry.py, test_send_multiple_images.py,
test_stream_consumer.py, test_ws_auth_retry.py) get
`gateway.platforms.mattermost` → `plugins.platforms.mattermost.adapter`
with the bulk-rewrite recipe from the platform-plugin-migration playbook.
Single `mock.patch` string in test_stream_consumer.py also repointed.
* `tests/tools/test_send_message_missing_platforms.py`: thin
`(token, extra, chat_id, message)` compat shim around the plugin's
`_standalone_send(pconfig, …)` so existing test bodies continue to
work without rewriting every signature.
Validation
----------
* Plugin discovery: mattermost registers from `plugins/platforms/mattermost/`
alongside discord / teams / irc / line / google_chat / simplex.
All 9 hooks present (setup_fn, standalone_sender_fn,
apply_yaml_config_fn, is_connected, check_fn, allowed_users_env,
allow_all_env, cron_deliver_env_var, max_message_length=4000).
* Mattermost-touching tests: 62/62 pass
(`test_mattermost.py` + `test_send_message_missing_platforms.py`).
* Targeted selectors (mattermost or platform_registry or stream_consumer
or ws_auth_retry or media_download_retry or send_multiple_images or
send_message_tool or platform_connected): 433/433 pass.
* Full sweep (`scripts/run_tests.sh tests/gateway/ tests/cron/
tests/tools/test_send_message_tool.py tests/tools/test_send_message_missing_platforms.py
tests/integration/`): **6220/6220 pass in 47.8s, 0 failures**.
* Lint: ruff clean on all touched files.
* Git identity verified: kshitijk4poor.
* Rename detection: R071 (similarity dropped from a hypothetical R09x
by the ~320-line appended register block — ~36% growth over the
873-LoC base, vs Discord's 5101 LoC base which kept R091).
Closes part of #3823.
Robustness:
- Surface 401/404 stream failures via _set_fatal_error() so the gateway's
runtime status reflects 'fatal: ntfy_unauthorized' / 'ntfy_topic_not_found'
instead of staying 'connected' when the reconnect loop halts. Matches
the pattern in whatsapp / telegram / sms adapters.
- Strip whitespace from auth tokens so pasted tokens with trailing
newlines don't produce malformed Authorization headers.
Simplicity:
- Extract _build_auth_header() and _truncate_body() to module-level
helpers, used by both NtfyAdapter and _standalone_send. Removes the
duplicated auth/truncation logic between the two paths.
Docs:
- website/docs/user-guide/messaging/ntfy.md — full setup guide,
identity-model warning, self-hosting, cron usage, troubleshooting.
- website/docs/reference/environment-variables.md — all 9 NTFY_* vars.
- website/docs/user-guide/messaging/index.md — platform comparison row.
- website/sidebars.ts — sidebar entry between simplex and open-webui.
Tests: 78/78 (+ 10 new robustness tests covering token hygiene, fatal
error propagation for 401/404, and the _truncate_body helper).
ntfy now ships as a self-contained plugin under plugins/platforms/ntfy/
instead of editing 8 core files (gateway/config.py Platform enum,
gateway/run.py factory + auth maps, cron/scheduler.py, toolsets.py,
hermes_cli/status.py, agent/prompt_builder.py, gateway/channel_directory.py,
tools/send_message_tool.py).
All routing goes through gateway/platform_registry via register_platform():
- adapter_factory, check_fn, validate_config, is_connected
- env_enablement_fn seeds PlatformConfig.extra from NTFY_* env vars so
gateway status reflects env-only setups without instantiating httpx
- standalone_sender_fn handles deliver=ntfy cron jobs when cron runs
out-of-process from the gateway
- allowed_users_env / allow_all_env hook into _is_user_authorized
- cron_deliver_env_var=NTFY_HOME_CHANNEL for cron home routing
- platform_hint surfaces in the system prompt
- pii_safe=True (topic names are the only identifier; no PII to redact)
Tests moved to tests/gateway/test_ntfy_plugin.py using _plugin_adapter_loader
so the module lives under plugin_adapter_ntfy in sys.modules and cannot
collide with sibling plugin-adapter tests on the same xdist worker. The
core-file grep tests (Platform.NTFY in source, hermes-ntfy in toolsets,
etc.) are replaced with plugin-shape tests covering register() metadata,
env_enablement_fn output, and standalone_sender_fn behavior.
68 tests pass under scripts/run_tests.sh.
Two bugs surfaced by PR #24356 migrating Discord into the registry:
1. plugins/platforms/discord/adapter.py::_is_connected — read DISCORD_BOT_TOKEN
via hermes_cli.gateway.get_env_value (the abstraction tests patch) instead
of os.getenv directly. The legacy non-registry path used get_env_value;
bypassing it broke test_setup_openclaw_migration which patches
gateway_mod.get_env_value to simulate a hermetic env.
2. hermes_cli/gateway.py::_platform_status — when entry.is_connected is
defined and returns False, return 'not configured' immediately. Don't
fall back to entry.check_fn(), which would let 'SDK is installed'
override 'no token configured' and incorrectly report the platform as
ready. The fallback to check_fn is the right behaviour only when
is_connected is None (not registered).
Fixes 5 test failures observed on CI for PR #24356:
- tests/hermes_cli/test_setup.py::test_setup_gateway_skips_service_install_when_systemctl_missing
- tests/hermes_cli/test_setup.py::test_setup_gateway_in_container_shows_docker_guidance
- tests/hermes_cli/test_setup_irc.py::TestIRCGatewaySetupFreshInstall::test_setup_gateway_irc_counts_as_messaging_platform
- tests/hermes_cli/test_setup_openclaw_migration.py::TestGetSectionConfigSummary::test_gateway_returns_none_without_tokens
- tests/hermes_cli/test_setup_openclaw_migration.py::TestSetupWizardSkipsConfiguredSections::test_sections_skipped_when_migration_imported_settings
Same _platform_status bug exists for sibling plugin platforms (teams,
google_chat) whose check_fn returns true on SDK install alone; their
tests just never exercised the registry path before. The bug only became
test-visible when Discord migrated into the registry.
Validation: 11,167 tests across tests/gateway/ + tests/cron/ +
tests/tools/test_send_message_tool.py + tests/hermes_cli/ pass with zero
failures.
First migration of an existing built-in platform adapter to the plugin
system established by IRC / Teams / LINE / Google Chat. Closes#24325;
advances the umbrella refactor in #3823.
Matches Teams' shape exactly — adapter under ``plugins/platforms/discord/``
with the standard ``__init__.py`` / ``adapter.py`` / ``plugin.yaml``
shell, ``register(ctx)`` entry point, **no back-compat shim** at the old
import path, and full parity for the four hooks Teams uses plus the
``apply_yaml_config_fn`` hook that landed in #25443 (the Discord plugin
is the first consumer of that hook):
* ``standalone_sender_fn`` — out-of-process cron delivery via REST API
* ``setup_fn`` — interactive ``hermes setup gateway`` wizard
* ``apply_yaml_config_fn`` — translate ``config.yaml`` ``discord:`` keys
into ``DISCORD_*`` env vars (replaces the hardcoded block in
``gateway/config.py``)
* ``is_connected`` — declares connection state from ``DISCORD_BOT_TOKEN``
* ``check_fn`` — lazy-installs ``discord.py`` on demand
* plus ``allowed_users_env``, ``allow_all_env``, ``cron_deliver_env_var``,
``max_message_length``, ``emoji``, ``required_env``, ``install_hint``
* ``gateway/platforms/discord.py`` (5,101 LOC) →
``plugins/platforms/discord/adapter.py`` (git rename, R090).
* New ``plugins/platforms/discord/{__init__.py, plugin.yaml}`` with
``requires_env`` / ``optional_env`` declarations.
* Append ``register(ctx)`` block + new hook implementations
(``_standalone_send``, ``interactive_setup``, ``_apply_yaml_config``,
``_clean_discord_user_ids``, ``_is_connected``, ``_build_adapter``,
plus helpers ``_DISCORD_CHANNEL_TYPE_PROBE_CACHE`` etc.) to the
adapter.
* Replace the ``Platform.DISCORD elif`` branch in
``GatewayRunner._create_adapter()`` (−9 LOC) with a generic post-creation
hook (+6 LOC) in the registry path: any plugin adapter that declares a
``gateway_runner`` attribute now gets it auto-injected. Webhook's
built-in branch is unchanged (it doesn't go through the registry path).
* Move ``_send_discord`` (190 LOC) and helpers
(``_DISCORD_CHANNEL_TYPE_PROBE_CACHE``, ``_remember_channel_is_forum``,
``_probe_is_forum_cached``, ``_derive_forum_thread_name``) from
``tools/send_message_tool.py`` into the plugin as ``_standalone_send``.
* Wire via ``standalone_sender_fn=_standalone_send`` (Teams pattern; same
gap fixed in #21804 for other plugin platforms).
* Replace the Discord ``elif`` in ``tools/send_message_tool.py``
``_send_to_platform`` with a 10-line registry-hook dispatch.
* Drop the ``DiscordAdapter`` import and the
``Platform.DISCORD: DiscordAdapter.MAX_MESSAGE_LENGTH`` ``_MAX_LENGTHS``
entry — the registry's ``max_message_length=2000`` covers it.
* Move ``_setup_discord`` and ``_clean_discord_user_ids`` (68 LOC) from
``hermes_cli/setup.py`` into the plugin as ``interactive_setup``.
* Wire via ``setup_fn=interactive_setup``. CLI helpers (``prompt``,
``print_info``, etc.) are lazy-imported so the plugin's module-load
surface stays minimal.
* Remove ``"discord": _s._setup_discord`` from
``hermes_cli/gateway.py::_builtin_setup_fn``.
* Remove the entire 32-line ``_PLATFORMS["discord"]`` static dict entry —
Discord's setup metadata is now discovered dynamically via
``_all_platforms()`` from the registry entry.
* Move the 59-line ``discord_cfg`` YAML→env bridge from
``gateway/config.py::load_gateway_config()`` into the plugin as
``_apply_yaml_config``. Covers ``require_mention``,
``thread_require_mention``, ``free_response_channels``, ``auto_thread``,
``reactions``, ``ignored_channels``, ``allowed_channels``,
``no_thread_channels``, ``allow_mentions.{everyone,roles,users,
replied_user}``, and ``reply_to_mode`` (including the YAML 1.1
``off``-as-False coercion and the ``extra.reply_to_mode`` fallback).
* Wire via ``apply_yaml_config_fn=_apply_yaml_config``.
* The hook runs BEFORE ``_apply_env_overrides`` and after the generic
shared-key loop, exactly as documented in
``website/docs/developer-guide/adding-platform-adapters.md``.
* Behavior is preserved exactly — every assignment still uses
``not os.getenv(...)`` guards so env vars take precedence over YAML.
All 78 references to the old import path are rewritten — no back-compat
shim:
* 51 ``from gateway.platforms.discord import X`` →
``from plugins.platforms.discord.adapter import X``
* 5 ``import gateway.platforms.discord as discord_platform`` →
``import plugins.platforms.discord.adapter as discord_platform``
* 1 ``from gateway.platforms import discord as discord_mod`` →
``from plugins.platforms.discord import adapter as discord_mod``
* 21 ``mock.patch("gateway.platforms.discord.X")`` strings →
``mock.patch("plugins.platforms.discord.adapter.X")``
* 1 docstring reference in ``hermes_cli/commands.py``
* 1 import in ``tools/send_message_tool.py`` (now removed entirely)
The import-safety test in ``tests/gateway/test_discord_imports.py`` is
updated to purge the new canonical module name from ``sys.modules``.
**38 files changed, +621 / −473** — net positive due to the YAML hook
implementation (89 new LOC in the plugin trading for 59 deleted in core),
but every line moved has a clear plugin home now. The git rename is
detected at R090 because the adapter gained ~340 LOC of moved-in hook
implementations (``_standalone_send`` + ``interactive_setup`` +
``_apply_yaml_config`` + helpers).
* All 568 Discord-specific tests pass across 25 ``test_discord_*.py``
files plus voice/send/text-batching/reload-skills/stream-consumer/
integration tests.
* All 147 tests in the YAML-touching subset
(``test_discord_reply_mode``, ``test_discord_free_response``,
``test_discord_allowed_channels``, ``test_discord_allowed_mentions``,
``test_discord_channel_controls``, ``test_discord_reactions``,
``test_discord_thread_persistence``, ``test_runtime_footer``) pass —
this is the strongest signal that the YAML→env hook behaves
identically to the legacy block.
* Broader gateway/cron/integration sweep (1297 tests) introduces zero
new failures vs ``main``. Pre-existing failures in
``tests/gateway/test_tts_media_routing.py`` and
``tests/e2e/test_platform_commands.py`` reproduce identically on the
unchanged ``main`` revision.
* Plugin discovery sanity check confirms Discord registers alongside the
other four platform plugins:
Registered platforms: ['discord', 'google_chat', 'irc', 'line', 'teams']
These Discord-shaped tendrils in core were **deliberately not moved** —
they are generic platform-registry concerns affecting every platform,
not Discord-specific:
* ``gateway/config.py:1205`` ``DISCORD_BOT_TOKEN → config.token`` env
enablement — same shape Telegram has. The existing
``env_enablement_fn`` registry hook only seeds ``extra``, not
``.token``, so it can't replace this without an adapter refactor to
read from ``extra["bot_token"]``.
* ``gateway/run.py`` voice-mode hooks
(``self.adapters.get(Platform.DISCORD)`` for
``start_voice_mode``/``stop_voice_mode``), role-based auth,
``DISCORD_ALLOW_BOTS`` branch in ``_is_user_authorized``,
``_UPDATE_ALLOWED_PLATFORMS`` frozenset, and the per-platform
allowlist maps — generic platform-registry concerns.
* ``Platform.DISCORD`` enum literal — stable identifier used as dict
keys throughout the codebase; removing it is a separate refactor with
no real benefit.
* ``tools/discord_tool.py`` and ``tools/environments/local.py`` —
first-class agent tools and env-passthrough config, neither is the
gateway adapter.
Each of these is worth its own scoping issue when the time comes.
Six days after #23937 (608 fixes) the codebase had accumulated 241 new
PLR6201 violations. Same mechanical `x in (...)` → `x in {...}` fix,
same zero-risk profile: set lookup is O(1) vs O(n) for tuple and the
two are semantically equivalent for hashable scalar membership tests.
All 241 instances fixed via `ruff check --select PLR6201 --fix
--unsafe-fixes`, zero remaining. Every changed value is a hashable
scalar (str/int/None/enum/signal); no risk of unhashable runtime
errors. No behavior change.
Test plan:
- 119 files changed, +244/-244 (net zero) — exactly one-line edits
- `ruff check` clean afterward
- Compile checks pass on the largest touched files (cli.py, run_agent.py,
gateway/run.py, gateway/platforms/discord.py, model_tools.py)
- Subset broad test run on tests/gateway/ tests/hermes_cli/ tests/agent/
tests/tools/: 18187 passed, 59 pre-existing failures (verified against
origin/main with the same shape — identical failure count, identical
category — all xdist test-order flakes unrelated to this change)
Follows the same template as PR #23937 ([tracker: #23972](https://github.com/NousResearch/hermes-agent/issues/23972)).
_LineClient's five aiohttp.ClientSession() calls omit trust_env=True,
silently bypassing HTTP_PROXY / HTTPS_PROXY / ALL_PROXY. Result: every
LINE API call (reply, push, loading, fetch_content, get_bot_user_id)
ignores the system proxy.
Fix: add trust_env=True to all five session constructions. Symmetric
with the wecom and weixin adapters which already set this flag. No
behavior change for users not behind a proxy.
aiohttp.ClientSession defaults to trust_env=False, which silently ignores
HTTP_PROXY, HTTPS_PROXY, and ALL_PROXY environment variables. Users behind
a corporate or network proxy cannot reach external APIs on any of these
platforms — all outbound requests fail with connection errors.
Symmetric with wecom.py (line 276), weixin.py (lines 1055/1268/1274), and
matrix.py (no-proxy path) which already set this flag. Complements the
open LINE fix (#26635) with the remaining gateway and plugin adapters.
Changed:
- gateway/platforms/sms.py: persistent Twilio session (connect) + fallback
session (send) — both hit https://api.twilio.com
- gateway/platforms/slack.py: ephemeral response_url POST session —
hits https://hooks.slack.com/... callback URLs
- plugins/platforms/teams/adapter.py: standalone send session —
hits login.microsoftonline.com (token) + Bot Framework service URL
- plugins/platforms/google_chat/adapter.py: standalone send session —
hits https://chat.googleapis.com/v1/...
WhatsApp sessions are excluded: they connect to http://127.0.0.1:{port}
(local bridge) and must not be routed through a system proxy.
Wraps every sync->async coroutine-scheduling site in the codebase with a
new agent.async_utils.safe_schedule_threadsafe() helper that closes the
coroutine on scheduling failure (closed loop, shutdown race, etc.)
instead of leaking it as 'coroutine was never awaited' RuntimeWarnings
plus reference leaks.
22 production call sites migrated across the codebase:
- acp_adapter/events.py, acp_adapter/permissions.py
- agent/lsp/manager.py
- cron/scheduler.py (media + text delivery paths)
- gateway/platforms/feishu.py (5 sites, via existing _submit_on_loop helper
which now delegates to safe_schedule_threadsafe)
- gateway/run.py (10 sites: telegram rename, agent:step hook, status
callback, interim+bg-review, clarify send, exec-approval button+text,
temp-bubble cleanup, channel-directory refresh)
- plugins/memory/hindsight, plugins/platforms/google_chat
- tools/browser_supervisor.py (3), browser_cdp_tool.py,
computer_use/cua_backend.py, slash_confirm.py
- tools/environments/modal.py (_AsyncWorker)
- tools/mcp_tool.py (2 + 8 _run_on_mcp_loop callers converted to
factory-style so the coroutine is never constructed on a dead loop)
- tui_gateway/ws.py
Tests: new tests/agent/test_async_utils.py covers helper behavior under
live loop, dead loop, None loop, and scheduling exceptions. Regression
tests added at three PR-original sites (acp events, acp permissions,
mcp loop runner) mirroring contributor's intent.
Live-tested end-to-end:
- Helper stress test: 1500 schedules across live/dead/race scenarios,
zero leaked coroutines
- Race exercised: 5000 schedules with loop killed mid-flight, 100 ok /
4900 None returns, zero leaks
- hermes chat -q with terminal tool call (exercises step_callback bridge)
- MCP probe against failing subprocess servers + factory path
- Real gateway daemon boot + SIGINT shutdown across multiple platform
adapter inits
- WSTransport 100 live + 50 dead-loop writes
- Cron delivery path live + dead loop
Salvages PR #2657 — adopts contributor's intent over a much wider site
list and a single centralized helper instead of inline try/except at
each site. 3 of the original PR's 6 sites no longer exist on main
(environments/patches.py deleted, DingTalk refactored to native async);
the equivalent fix lives in tools/environments/modal.py instead.

SimpleX Chat (https://simplex.chat) is a private, decentralised messenger
with no persistent user IDs — every contact is identified by an opaque
internal ID generated at connection time. This adds it as a Hermes
gateway platform via the plugin system.
The adapter connects to a local simplex-chat daemon via WebSocket,
listens for inbound messages, and sends replies. Originally proposed in
PR #2558 as a core-modifying integration; reshaped here as a self-
contained plugin under plugins/platforms/simplex/ with no edits to any
core file. Discovery is filesystem-based (scanned by gateway.config),
and the platform identity is resolved on demand via Platform("simplex").
Plugin contract:
- check_requirements() requires SIMPLEX_WS_URL AND the websockets package
- validate_config() / is_connected() accept env or config.yaml input
- _env_enablement() seeds PlatformConfig.extra (ws_url + home_channel)
- _standalone_send() supports out-of-process cron delivery
- interactive_setup() provides a stdin wizard for hermes gateway setup
- register() wires the adapter into the registry with required_env,
install_hint, cron_deliver_env_var, allowed_users_env, and a
platform_hint for the LLM.
Lazy dependency: the websockets Python package is imported inside the
functions that need it. The plugin is importable and discoverable even
when websockets is missing — check_requirements() simply returns False
until `pip install websockets` is run. No new pyproject extras are
introduced.
Environment variables:
SIMPLEX_WS_URL WebSocket URL of the daemon (required)
SIMPLEX_ALLOWED_USERS Comma-separated allowed contact IDs
SIMPLEX_ALLOW_ALL_USERS Set true to allow all contacts
SIMPLEX_HOME_CHANNEL Default contact for cron delivery
SIMPLEX_HOME_CHANNEL_NAME Human label for the home channel
Closes#2557.
The LINE adapter calls self.create_source(...) which raises
AttributeError on every inbound message — no such method exists.
The base PlatformAdapter exposes this factory as build_source(),
consistent with the IRC and Teams adapters.
Fixes#23728
* feat(gateway): add LINE Messaging API platform plugin
Adds LINE as a bundled platform plugin under `plugins/platforms/line/`,
synthesized from the strongest pieces of seven open community PRs. 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/<token>/<filename>` 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

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.

* docs(platforms): document platform-specific slow-LLM UX pattern
Add a 'Platform-Specific Slow-LLM UX' section to the platform-adapter
developer guide covering the _keep_typing override pattern that LINE
uses for its Template Buttons postback flow.
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. Documenting now while the rationale is fresh.

Same pattern as the google_chat lazy-load (PR #22681), applied to the
Teams plugin. The bundled `plugins/platforms/teams/adapter.py` did
`import httpx` at module top, which dragged the entire httpx +
httpcore stack into every process that triggered plugin discovery —
including `hermes` invocations that never instantiate the Teams
adapter.
`httpx` is only needed inside one method
(`TeamsMeetingPipeline._write_summary_via_incoming_webhook`), and the
`httpx.AsyncBaseTransport` parameter annotation is already string-only
thanks to the existing `from __future__ import annotations`. Move the
runtime import inside the method.
Measured impact (7-run medians, 9950X3D):
teams plugin alone: 118 → 89 ms (-25%)
46 → 38 MB (-17%)
import cli (full): unchanged
import model_tools: unchanged
The full-CLI numbers are flat because httpx is loaded transitively
from many other modules on that path. The microbench win is the real
signal: 29 ms / 8 MB shaved off any process that touches the teams
plugin without otherwise pulling httpx — primarily future workflows
where the gateway is enabled but Teams is not configured.
Tests: 44/44 `tests/gateway/test_teams.py` pass; 345 across all
plugin-platform suites (teams + qqbot + google_chat). The test file
imports `httpx` itself for the `MockTransport` fixture, which is
correct — tests legitimately use httpx, only the plugin's module-level
import was the issue.
Plugin discovery imports every bundled platform plugin at model_tools
import time. The google_chat adapter unconditionally pulled in
google.cloud.pubsub_v1, googleapiclient, grpc, httplib2, and friends at
module top — about 33 MB RSS and 110 ms wall on every CLI invocation,
even ones that never construct a gateway adapter.
Wrap the heavy imports in _load_google_modules(): an idempotent loader
that rebinds the module-level globals (pubsub_v1, service_account,
HttpError, MediaFileUpload, …) on first call and is invoked from
GoogleChatAdapter.__init__, connect(), and check_google_chat_requirements().
The HttpError = Exception placeholder is preserved for the brief window
before the loader runs, so 'except HttpError as exc:' clauses stay
correct (Python looks up the name at try/except evaluation time, not
at function definition time).
Measured impact on a 9950X3D, 7-run medians:
import cli: 895 → 787 ms (-108 ms / -12%)
133 → 110 MB ( -23 MB / -17%)
import model_tools: 491 → 400 ms ( -91 ms / -19%)
95 → 66 MB ( -29 MB / -31%)
google_chat alone: 244 → 132 ms (-112 ms / -46%)
83 → 50 MB ( -33 MB / -40%)
hermes chat -q (cold): 177 → 145 MB ( -32 MB / -18%)
Real-world win lands on every path that imports cli.py: hermes chat,
hermes gateway, cron jobs, batch runs, subagents. Long-lived gateway
processes save ~30 MB resident.
All 157 google_chat tests pass; full gateway suite (5050 tests) green.
Plugin platforms (IRC, Teams, Google Chat) currently fail with
`No live adapter for platform '<name>'` when a `deliver=<plugin>` cron
job runs in a separate process from the gateway, even though the
platforms are eligible cron targets via `cron_deliver_env_var` (added
in #21306). Built-in platforms (Telegram, Discord, Slack, etc.) use
direct REST helpers in `tools/send_message_tool.py` so cron can deliver
without holding the gateway in the same process; plugin platforms
historically depended on `_gateway_runner_ref()` which returns `None`
out of process.
This change adds an optional `standalone_sender_fn` field to
`PlatformEntry` so plugins can register an ephemeral send path that
opens its own connection, sends, and closes without needing the live
adapter. The dispatch site in `_send_via_adapter` falls through to the
hook when the gateway runner is unavailable, with a descriptive error
when neither path applies. The hook is optional, so existing plugins
are unaffected.
Reference migrations land in the same change for IRC, Teams, and
Google Chat, exercising the hook across stdlib (asyncio + IRC protocol),
Bot Framework OAuth client_credentials, and Google service-account
flows respectively.
Security hardening on the new code paths:
* IRC: control-character stripping on chat_id and message body to
block CRLF command injection; bounded nick-collision retries; JOIN
before PRIVMSG so channels with the default `+n` mode accept the
delivery.
* Teams: TEAMS_SERVICE_URL validated against an allowlist of known
Bot Framework hosts (`smba.trafficmanager.net`,
`smba.infra.gov.teams.microsoft.us`) to block SSRF; chat_id and
tenant_id constrained to the documented Bot Framework character set;
per-request timeouts so a slow STS endpoint cannot starve the
activity POST.
* Google Chat: chat_id and thread_id validated against strict
resource-name regexes; service-account refresh wrapped in
`asyncio.wait_for` so a hung token endpoint cannot stall the
scheduler.
Test coverage: 20 new tests covering happy path, missing-config errors,
network failure modes, and each defensive validation. Existing tests
unchanged. `bash scripts/run_tests.sh tests/tools/test_send_message_tool.py
tests/gateway/test_irc_adapter.py tests/gateway/test_teams.py
tests/gateway/test_google_chat.py` reports 341 passed, 0 regressions.
Documentation: new "Out-of-process cron delivery" section in
website/docs/developer-guide/adding-platform-adapters.md and an entry
in gateway/platforms/ADDING_A_PLATFORM.md naming the hook.
Adds five regression tests for the Format 3 (Cloud Run relay) envelope
path:
- test_relay_flat_honors_declared_sender_type_bot: BOT sender_type
propagates to msg['sender']['type'].
- test_relay_flat_defaults_sender_type_human_when_absent: backward
compat \u2014 missing field still flows as HUMAN.
- test_relay_flat_coerces_unknown_sender_type_to_human: defensive
coercion \u2014 strip+upper normalizes whitespace/case, anything outside
{HUMAN, BOT} falls back to HUMAN.
- test_relay_flat_bot_sender_is_filtered_end_to_end: end-to-end
through _on_pubsub_message \u2014 a relay envelope with sender_type=BOT
is dropped by the BOT self-filter without dispatch.
- test_relay_flat_human_sender_dispatches: end-to-end negative
control \u2014 human relay envelopes still reach the agent loop.
Also clarifies the operator contract in the adapter comment: the
relay must forward upstream sender.type as envelope.sender_type,
otherwise bot replies forwarded as HUMAN cannot be distinguished
from genuine humans by this filter.
Adopt the generic platform-plugin hooks landed in the preceding commit
so IRC and Teams get env-only config detection and cron home-channel
delivery without living in cron/scheduler.py's hardcoded sets.
IRC (plugins/platforms/irc/):
- adapter.py: new _env_enablement() seeds server, channel, port,
nickname, use_tls, server_password, nickserv_password, and a
home_channel dict into PlatformConfig on env-only setups.
IRC_HOME_CHANNEL defaults to IRC_CHANNEL so deliver=irc cron jobs
route to the joined channel by default.
- adapter.py: register_platform() gains env_enablement_fn=_env_enablement
and cron_deliver_env_var='IRC_HOME_CHANNEL'.
- plugin.yaml: rich requires_env / optional_env with description,
prompt, password, url for every IRC env var. Hardcoded IRC entries
in hermes_cli/config.py still win (back-compat), but the plugin now
carries its own metadata.
Teams (plugins/platforms/teams/):
- adapter.py: new _env_enablement() seeds client_id, client_secret,
tenant_id, port, and home_channel into PlatformConfig. Closes the
long-standing gap where TEAMS_HOME_CHANNEL was documented but never
wired up.
- adapter.py: register_platform() gains env_enablement_fn=_env_enablement
and cron_deliver_env_var='TEAMS_HOME_CHANNEL' — deliver=teams cron
jobs now work.
- plugin.yaml: rich requires_env / optional_env with description,
prompt, password, url for every Teams env var. Surfaces them in
'hermes config' UI for the first time (Teams had no OPTIONAL_ENV_VARS
entries before this).
Zero behavior change for existing users: env_enablement_fn is only
called when env vars are set, and the registry's config-first-env-fallback
path in validate_config / is_connected is unchanged.
Adds Google Chat as a new gateway platform, shipped under
plugins/platforms/google_chat/ following the canonical bundled-plugin
pattern (Teams, IRC). Rewired from the original PR #18425 to use the
new env_enablement_fn + cron_deliver_env_var plugin interfaces landed
in the preceding commit, so the adapter touches ZERO core files.
What it does:
- Inbound DM + group messages via Cloud Pub/Sub pull subscription (no
public URL needed), with attachments (PDFs, images, audio, video)
downloaded through an SSRF-guarded Google-host allowlist.
- Outbound text replies with the 'Hermes is thinking…' patch-in-place
pattern — no tombstones.
- Native file attachment delivery via per-user OAuth. Google Chat's
media.upload endpoint rejects service-account auth, so each user
runs /setup-files once in their own DM to grant
chat.messages.create for themselves; the adapter then uploads as
them. Tokens stored per email at
~/.hermes/google_chat_user_tokens/<email>.json.
- Thread isolation: side-threads get isolated sessions, top-level DM
messages share one continuous session. Persistent thread-count
store survives gateway restart.
- Supervisor reconnect with exponential backoff.
- Multi-user out of the box.
How it plugs in (no core edits):
- env_enablement_fn seeds PlatformConfig.extra with project_id,
subscription_name, service_account_json, and the home_channel dict
(which the core hook turns into a HomeChannel dataclass). Reads
GOOGLE_CHAT_PROJECT_ID (falls back to GOOGLE_CLOUD_PROJECT),
GOOGLE_CHAT_SUBSCRIPTION_NAME (falls back to GOOGLE_CHAT_SUBSCRIPTION),
GOOGLE_CHAT_SERVICE_ACCOUNT_JSON (falls back to
GOOGLE_APPLICATION_CREDENTIALS), GOOGLE_CHAT_HOME_CHANNEL.
- cron_deliver_env_var='GOOGLE_CHAT_HOME_CHANNEL' gets cron delivery
for free — cron/scheduler.py consults the platform registry for any
name not in its hardcoded built-in sets.
- plugin.yaml's rich requires_env / optional_env blocks auto-populate
OPTIONAL_ENV_VARS via the new hermes_cli/config.py injector, so
'hermes config' UI surfaces them with description / url / prompt /
password metadata.
- Module-level Platform('google_chat') call in adapter.py triggers the
Platform._missing_() registration so Platform.GOOGLE_CHAT attribute
access works without an enum entry.
Distribution: ships inside the existing hermes-agent package. Users
opt in via 'pip install hermes-agent[google_chat]' and follow the
8-step GCP walkthrough at
website/docs/user-guide/messaging/google_chat.md.
Test coverage: 153 tests in tests/gateway/test_google_chat.py, all
passing. Spans platform registration, env config loading, Pub/Sub
envelope routing, outbound send + chunking + typing patch-in-place,
attachment send paths, SSRF guard, thread/session model,
supervisor reconnect, authorization, per-user OAuth, and the new
plugin-registry cron delivery wiring.

The previous bare except swallowed every exception from app.reply()
silently. Log at debug so real failures (auth, chat gone) leave a
trace while keeping the group-chat 400 fallback working. Also fix
the Teams entry's indentation in the messaging flowchart.
Group chats return 400 for threaded sends. Catch the error and
fall back to a flat send so messages always get delivered.

The Teams adapter's interactive_setup() tried to import prompt,
prompt_yes_no, print_info, print_success, and print_warning from
hermes_cli.config, but those helpers live in hermes_cli.cli_output.
Only get_env_value/save_env_value live in hermes_cli.config.
This caused 'hermes setup' to crash with ImportError as soon as the
user picked Teams in the messaging-platforms wizard.
Split the import accordingly.
microsoft-teams-apps 2.0.0 added the `client` option to AppOptions,
accepting a ClientOptions instance. Use it to set the User-Agent

The gateway calls send_image_file() for locally cached images
(e.g. from image_gen tools). Without this override the base class
falls back to sending the file path as plain text. Delegate to
send_image() which already handles base64 encoding local paths.
