When Hermes runs in TUI mode, the gateway child process communicates with
the Node.js parent over a JSON-RPC protocol on stdin. Subprocess calls that
inherit this stdin fd can trigger a race condition where the child's stdin
read returns EOF, causing the gateway to exit cleanly (exit code 0) mid-tool-
execution.
This is the same root cause as issue #14036 (byterover plugin) and PR #39257
(SSH environment backend). This commit applies the fix — stdin=subprocess.DEVNULL
— to all 85 subprocess.run() and subprocess.Popen() calls that execute inside
the TUI gateway child process.
Scope: TUI-context code only (agent/, tools/, plugins/, tui_gateway/server.py).
CLI code (cli.py, hermes_cli/), tests, scripts, and gateway process management
are excluded — they don't run inside the TUI child and inherit the terminal's
stdin, not the JSON-RPC pipe.
85 call sites across 28 files. All files pass syntax check.
Tool-progress now shows a terminal command in a ```bash fenced block —
full command, no surrounding quotes, no label, no 40-char truncation —
instead of the noisy `terminal: "cmd…"` line, on every platform that
renders markdown code blocks (Telegram, Slack, Matrix, WhatsApp, Feishu,
Weixin, Discord). Plain-text platforms keep the compact preview line.
Gated on a new `BasePlatformAdapter.supports_code_blocks` capability
(default False) rather than a hardcoded platform list, so plugin adapters
(Discord lives in plugins/platforms/) opt in by setting the flag. Applies
to both all/new and verbose progress modes, with a safe fallback when the
command arg is missing or blank.
Salvage of the Discord half of PR #30964 by @LaPhilosophie. Discord
component button callbacks (ExecApprovalView, SlashConfirmView,
UpdatePromptView, ModelPickerView) bypass the normal message dispatch
authorization path. _component_check_auth previously returned True when
both the user and role allowlists were empty, so any guild member who
could see an approval prompt could click Approve on a dangerous command.
Fail closed instead: require DISCORD_ALLOWED_USERS / DISCORD_ALLOWED_ROLES
/ GATEWAY_ALLOWED_USERS membership, or an explicit DISCORD_ALLOW_ALL_USERS
/ GATEWAY_ALLOW_ALL_USERS opt-in for deliberately-open deployments.
Mirrors the Telegram (#24457) and Matrix fail-closed precedent.
The Slack half of #30964 is superseded by PR #33844's helper.

* feat(discord): voice-channel mixer — ambient idle bed + verbal acks that overlap TTS
Discord voice mode can now feel conversational: the bot speaks a short
acknowledgement before it starts working, and a subtle ambient 'thinking' bed
plays underneath while tools run, ducking under speech and swelling back — the
Grok-voice-mode feel.
discord.py plays only one audio stream per voice connection, so this adds a
software mixer (VoiceMixer, a discord.AudioSource) installed once per guild on
join. It sums an ambient loop, verbal acks, and TTS replies into that single
20ms/48kHz/stereo stream (numpy int16 add + clip), so they overlap instead of
stop-and-swap. Speech ducks the ambient gain down and releases it smoothly.
- plugins/platforms/discord/voice_mixer.py: VoiceMixer + MixerChild (gain,
loop, fade, duck/release), decode_to_pcm (ffmpeg), synth_ambient_pcm (no
asset needed — synthesised pad).
- adapter: install mixer on join, tear down on leave, route
play_in_voice_channel through the mixer (legacy one-shot path kept as
fallback), play_ack_in_voice, voice_mixer_active. Defensive getattr for the
object.__new__ test helpers.
- gateway/run.py: tool_start_callback fires a one-time verbal ack on the first
tool call of a turn when in a voice channel (independent of the text
tool-progress gate). No system-prompt or message-flow changes.
- config: discord.voice_fx.* (OFF by default; ambient/duck/speech gains, ack
phrases). All in config.yaml, not .env.
- docs + tests (mixer unit + adapter integration).
Verified: 19 new tests pass, existing voice suite green (2 pre-existing
davey-module env failures unchanged), and a real-mixer E2E confirms ambient
streams, TTS overlaps it, acks layer in, and teardown is clean.
* fix(discord): make voice mixer numpy import lazy (numpy is voice-extra-only)
numpy ships in the optional 'voice' extra, not [all,dev], so a module-level
'import numpy' broke CI test collection (and would break the always-imported
Discord adapter on any install without the voice extra). Defer numpy to the
functions that actually mix audio via _require_numpy(); guard the test module
with pytest.importorskip('numpy').
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
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.
Co-authored-by: liuhao1024 <liuhao1024@users.noreply.github.com>
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.
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.
