_bot_participated_threads was an in-memory set — lost on every restart.
After restart, the bot forgot which threads it was active in, requiring
fresh @mentions and potentially creating duplicate threads instead of
continuing existing conversations.
Changes:
- Persist thread IDs to ~/.hermes/discord_threads.json
- Load on adapter init, save on every new thread participation
- _track_thread() replaces direct .add() calls for atomic persist
- Cap at 500 tracked threads to prevent unbounded growth
- /thread slash command also tracks participation
- 7 new tests covering persistence, restart survival, corruption
recovery, cap enforcement
* fix: prevent infinite 400 failure loop on context overflow (#1630)
When a gateway session exceeds the model's context window, Anthropic may
return a generic 400 invalid_request_error with just 'Error' as the
message. This bypassed the phrase-based context-length detection,
causing the agent to treat it as a non-retryable client error. Worse,
the failed user message was still persisted to the transcript, making
the session even larger on each attempt — creating an infinite loop.
Three-layer fix:
1. run_agent.py — Fallback heuristic: when a 400 error has a very short
generic message AND the session is large (>40% of context or >80
messages), treat it as a probable context overflow and trigger
compression instead of aborting.
2. run_agent.py + gateway/run.py — Don't persist failed messages:
when the agent returns failed=True before generating any response,
skip writing the user's message to the transcript/DB. This prevents
the session from growing on each failure.
3. gateway/run.py — Smarter error messages: detect context-overflow
failures and suggest /compact or /reset specifically, instead of a
generic 'try again' that will fail identically.
* fix(skills): detect prompt injection patterns and block cache file reads
Adds two security layers to prevent prompt injection via skills hub
cache files (#1558):
1. read_file: blocks direct reads of ~/.hermes/skills/.hub/ directory
(index-cache, catalog files). The 3.5MB clawhub_catalog_v1.json
was the original injection vector — untrusted skill descriptions
in the catalog contained adversarial text that the model executed.
2. skill_view: warns when skills are loaded from outside the trusted
~/.hermes/skills/ directory, and detects common injection patterns
in skill content ("ignore previous instructions", "<system>", etc.).
Cherry-picked from PR #1562 by ygd58.
* fix(tools): chunk long messages in send_message_tool before dispatch (#1552)
Long messages sent via send_message tool or cron delivery silently
failed when exceeding platform limits. Gateway adapters handle this
via truncate_message(), but the standalone senders in send_message_tool
bypassed that entirely.
- Apply truncate_message() chunking in _send_to_platform() before
dispatching to individual platform senders
- Remove naive message[i:i+2000] character split in _send_discord()
in favor of centralized smart splitting
- Attach media files to last chunk only for Telegram
- Add regression tests for chunking and media placement
Cherry-picked from PR #1557 by llbn.
* fix(approval): show full command in dangerous command approval (#1553)
Previously the command was truncated to 80 chars in CLI (with a
[v]iew full option), 500 chars in Discord embeds, and missing entirely
in Telegram/Slack approval messages. Now the full command is always
displayed everywhere:
- CLI: removed 80-char truncation and [v]iew full menu option
- Gateway (TG/Slack): approval_required message includes full command
in a code block
- Discord: embed shows full command up to 4096-char limit
- Windows: skip SIGALRM-based test timeout (Unix-only)
- Updated tests: replaced view-flow tests with direct approval tests

Two changes to align Discord behavior with Slack:
1. Auto-thread on @mention (default: true)
- When someone @mentions the bot in a server channel, a thread is
automatically created from their message and the response goes there.
- Each thread gets its own isolated session (like Slack).
- Configurable via discord.auto_thread in config.yaml (default: true)
or DISCORD_AUTO_THREAD env var (env takes precedence).
- DMs and existing threads are unaffected.
2. Skip @mention in bot-participated threads
- Once the bot has responded in a thread (auto-created or manually
entered), subsequent messages in that thread no longer require
@mention. Users can just type normally.
- Tracked via in-memory set (_bot_participated_threads). After a
gateway restart, users need to @mention once to re-establish.
- Threads the bot hasn't participated in still require @mention.
Config change:
discord:
auto_thread: true # new, added to DEFAULT_CONFIG
Tests: 7 new tests covering auto-thread default, disable, bot thread
participation tracking, and mention skip logic. All 903 gateway tests pass.
After bot leave/rejoin, Discord doesn't resend SPEAKING events for
users already in the channel. This left SSRC unmapped and all audio
was silently dropped by DAVE decrypt.
Fixes:
- Skip DAVE for unknown SSRCs instead of dropping (passthrough)
- Handle "UnencryptedWhenPassthroughDisabled" DAVE errors gracefully
- Auto-infer user_id from sole allowed member in voice channel
- Pass allowed_user_ids to VoiceReceiver for secure inference
Discord drops the UDP voice route after ~60s of silence - no packets
arrive even when users start speaking again. Send an Opus silence
frame every 15s to keep the UDP session alive.
play_tts was returning success without playing anything when bot was
in a voice channel. Now it calls play_in_voice_channel directly.
Simplified skip_double dedup: base adapter handles voice input TTS
via play_tts (which now works for VC), runner skips to avoid double.
Salvaged from PR #1115 onto current main by reusing the shared
Discord file-attachment helper for local video and document sends,
including file_name support for documents and regression coverage.
Prevent gateway.platforms.discord from crashing at import time when discord.py is unavailable. Python 3.11 eagerly evaluates annotations, so using discord.Interaction and similar annotations caused an AttributeError after the optional import fallback set discord=None. Add postponed annotation evaluation and a regression test covering import without discord installed.
1. Anthropic + ElevenLabs TTS silence: forward full response to TTS
callback for non-streaming providers (choices first, then native
content blocks fallback).
2. Subprocess timeout kill: play_audio_file now kills the process on
TimeoutExpired instead of leaving zombie processes.
3. Discord disconnect cleanup: leave all voice channels before closing
the client to prevent leaked state.
4. Audio stream leak: close InputStream if stream.start() fails.
5. Race condition: read/write _on_silence_stop under lock in audio
callback thread.
6. _vprint force=True: show API error, retry, and truncation messages
even during streaming TTS.
7. _refresh_level lock: read _voice_recording under _voice_lock.
- Change RTP packet logging from INFO to DEBUG level to reduce noise
(SPEAKING events remain at INFO as they are important lifecycle events)
- Use per-session chat_id (web_{session_id}) instead of shared "web"
to isolate conversation context between simultaneous web users
- Use hmac.compare_digest for timing-safe token comparison (3 endpoints)
- Default bind to 127.0.0.1 instead of 0.0.0.0
- Sanitize upload filenames with Path.name to prevent path traversal
- Add DOMPurify to sanitize marked.parse() output against XSS
- Replace add_static with authenticated media handler
- Hide token in group chats for /remote-control command
- Use ctypes.util.find_library for Opus instead of hardcoded paths
- Add force=True to 5 interrupt _vprint calls for visibility
- Log Opus decode errors and voice restart failures instead of swallowing
Duplicated YAML config parsing for stt.model existed in gateway/run.py
and gateway/platforms/discord.py. Moved to a single helper in
transcription_tools.py and added 5 tests covering all edge cases.
Code fixes:
- STT model, Groq base URL, and OpenAI STT base URL are now
configurable via env vars (STT_GROQ_MODEL, STT_OPENAI_MODEL,
GROQ_BASE_URL, STT_OPENAI_BASE_URL) instead of hardcoded
- Gateway and Discord VC now read stt.model from config.yaml
(previously only CLI did this — gateway always used defaults)
Doc fixes:
- voice-mode.md: move Web UI troubleshooting to web.md (was duplicated)
- voice-mode.md: simplify "How It Works" for end users (remove NaCl,
DAVE, RTP internals)
- voice-mode.md: clarify STT priority (OpenAI used first if both keys
set, Groq recommended for free tier)
- voice-mode.md: document new STT env overrides in config reference
- web.md: remove duplicate Quick Start / Step 1-3 sections
- web.md: add mobile HTTPS mic workarounds (moved from voice-mode.md)
- web.md: clarify STT fallback order
1. VoiceReceiver.stop() now acquires _lock before clearing shared state
to prevent race with _on_packet on the socket reader thread
2. _packet_debug_count moved from class-level to instance-level to avoid
cross-instance race condition in multi-guild setups
3. play_in_voice_channel uses asyncio.get_running_loop() instead of
deprecated asyncio.get_event_loop()
4. _send_voice_reply uses uuid for filenames instead of time-based names
that can collide when two replies happen in the same second
5. Voice timeout now notifies runner via _on_voice_disconnect callback
so runner cleans up _voice_mode state (prevents orphaned TTS replies)
6. play_in_voice_channel adds PLAYBACK_TIMEOUT (120s) to prevent
infinite blocking when FFmpeg callback is never called
7. _send_voice_reply moves temp file cleanup to finally block so files
are always cleaned up even when send_voice/play raises
8. Base adapter auto-TTS wraps play_tts in try/finally with os.remove
to clean up generated audio files after playback
18 new tests (120 total voice tests)
- Add lock protection around VoiceReceiver buffer writes in _on_packet
to prevent race condition with check_silence on different threads
- Wire _voice_input_callback BEFORE join_voice_channel to avoid
losing voice input during the join window
- Add try/except around leave_voice_channel to ensure state cleanup
(voice_mode, callback) even if leave raises an exception
- Guard against empty text after markdown stripping in base.py auto-TTS
- Add 11 tests proving each bug and verifying the fix
Override play_tts in DiscordAdapter to no-op when connected to a voice
channel for the same guild. The gateway runner already plays TTS audio
in the VC via play_in_voice_channel, so the base adapter's fallback
to send_voice (file attachment) was causing double audio output.
play_tts base class forwards metadata via **kwargs to send_voice,
but Discord and Slack adapters did not accept extra keyword arguments,
causing TypeError and silent message handling failure.
Also fix test_web_defaults to patch correct env var (WEB_UI_TOKEN).
Phase 2 of voice channel support: bot listens to users speaking in VC,
transcribes speech via Groq Whisper, and processes through the agent pipeline.
- Add VoiceReceiver class for RTP packet capture, NaCl/DAVE decryption, Opus decode
- Add silence detection and per-user PCM buffering
- Wire voice input callback from adapter to GatewayRunner
- Fix adapter dict key: use Platform.DISCORD enum instead of string
- Fix guild_id extraction for synthetic voice events via SimpleNamespace raw_message
- Pause/resume receiver during TTS playback to prevent echo
- Send Discord voice messages with flags=8192 and waveform metadata
so they render as native voice bubbles instead of file attachments
- Use .mp3 output path for TTS so edge-tts opus conversion works
correctly (edge always outputs mp3, convert was skipped for .ogg)
- Use actual file_path from TTS result after potential opus conversion
- Register /voice as Discord slash command with mode choices
- Fix _send_voice_reply to handle adapters that don't accept metadata
parameter (Discord) by inspecting the method signature at runtime
Add a /reasoning command across gateway adapters so users can
inspect or change reasoning effort without editing config by hand.
Reload reasoning settings from config.yaml before each agent run,
including background tasks, so the next message picks up the new
value consistently.
Users sometimes paste Discord IDs with prefixes like 'user:123456',
'<@123456>', or '<@!123456>' from Discord's UI or third-party tools.
This caused auth failures since the allowlist contained 'user:123' but
the actual user_id from messages was just '123'.
Fixes:
- Added _clean_discord_id() helper in discord.py to strip common prefixes
- Applied sanitization at runtime when parsing DISCORD_ALLOWED_USERS env var
- Applied sanitization in hermes setup and hermes gateway setup input flows
- Handles user:, <@>, and <@!> prefix formats
- Add /thread slash command that creates a Discord thread and starts a
new Hermes session in it. The starter message (if provided) becomes
the first user input in the new session.
- Add discord.auto_thread config option (DISCORD_AUTO_THREAD env var):
when enabled, every message in a text channel automatically creates
a thread, allowing parallel isolated sessions.
- Fix Discord media method signatures to accept metadata kwarg
(send_voice, send_image_file, send_image) — prevents TypeError
when the base adapter passes platform metadata.
- Fix test mock isolation: add app_commands and ForumChannel to
discord mocks so tests pass in full-suite runs.
Based on PRs #866 and #1109 by insecurejezza, modified per review:
removed /channel command (unsafe), added auto_thread feature,
made /thread dispatch new sessions.
Co-authored-by: insecurejezza <insecurejezza@users.noreply.github.com>
- Forum parent channel IDs now match free-response list (add a forum
channel ID and all its threads respond without mention)
- Better thread chat names: 'Guild / forum / thread' for forum threads
- Add discord.require_mention and discord.free_response_channels to
config.yaml (bridged to env vars, env vars still override)
- Keep require_mention defaulting to true (safe for shared servers)

Authored by aydnOktay. Replaces bare print statements with structured
logger calls (error/warning/info) and adds exc_info=True for stack
traces on failure paths.
Adds configurable bot message filtering via DISCORD_ALLOW_BOTS env var:
- 'none' (default): ignore all bot messages
- 'mentions': accept bots only when they @mention us
- 'all': accept all bot messages
Includes 8 tests.
Part 2 of thread_id forum topic fix: add metadata param to
send_voice, send_image, send_animation, send_typing in Telegram
adapter and pass message_thread_id to all Bot API calls. Update
send_typing signature in Discord, Slack, WhatsApp, HomeAssistant
for compatibility.
Based on the fix proposed by @Bitstreamono in PR #656.
Add configurable bot message filtering via DISCORD_ALLOW_BOTS env var:
- 'none' (default): Ignore all other bot messages — matches previous
behavior where only our own bot was filtered, but now ALL bots are
filtered by default for cleaner channels
- 'mentions': Accept bot messages only when they @mention our bot —
useful for bot-to-bot workflows triggered by mentions
- 'all': Accept all bot messages — for setups where bots need to
interact freely
Previously, we only ignored our own bot's messages, allowing all other
bots through. This could cause noisy loops in channels with multiple bots.
8 new tests covering all filter modes and edge cases.
Inspired by openclaw v2026.3.7 Discord allowBots: 'mentions' config.
Telegram: add /insights, /update, /reload_mcp (underscore variant since
Telegram BotCommand names don't allow hyphens).
Discord: add /insights (with days parameter), /reload-mcp.
Also add reload_mcp as an alias for reload-mcp in the gateway command
dispatcher so Telegram's underscore form works, and add resume/provider
to the _known_commands set for hook emission.
Add /title, /resume, /compress, /provider, /usage to Telegram's
set_my_commands so they appear in the / autocomplete menu.
Add /title, /resume, /compress, /provider, /usage, /help as Discord
slash commands so they appear in Discord's native command picker.
These commands were functional via text but not registered with the
platform-native command menus, so users couldn't discover them.
browser_vision now saves screenshots persistently to ~/.hermes/browser_screenshots/
and returns the screenshot_path in its JSON response. The model can include
MEDIA:<path> in its response to share screenshots as native photos.
Changes:
- browser_tool.py: Save screenshots persistently, return screenshot_path,
auto-cleanup files older than 24 hours, mkdir moved inside try/except
- telegram.py: Add send_image_file() — sends local images via bot.send_photo()
- discord.py: Add send_image_file() — sends local images via discord.File
- slack.py: Add send_image_file() — sends local images via files_upload_v2()
(WhatsApp already had send_image_file — no changes needed)
- prompt_builder.py: Updated Telegram hint to list image extensions,
added Discord and Slack MEDIA: platform hints
- browser.md: Document screenshot sharing and 24h cleanup
- send_file_integration_map.md: Updated to reflect send_image_file is now
implemented on Telegram/Discord/Slack
- test_send_image_file.py: 19 tests covering MEDIA: .png extraction,
send_image_file on all platforms, and screenshot cleanup
Partially addresses #466 (Phase 0: platform adapter gaps for send_image_file).
Building on PR #288's edit_message() abstraction:
- Telegram: edit_message_text() with MarkdownV2 + plain text fallback
- Discord: channel.fetch_message() + msg.edit() with length capping
- Slack: chat_update() via slack_bolt client
Also fixes the fallback regression in send_progress_messages() where
platforms that don't support editing would receive duplicated accumulated
tool lines. Now uses a can_edit flag — after the first failed edit, falls
back to sending individual lines (matching pre-PR behavior).
Adds a /update command to Telegram, Discord, and other gateway platforms
that runs `hermes update` to pull the latest code, update dependencies,
sync skills, and restart the gateway.
Implementation:
- Spawns `hermes update` in a separate systemd scope (systemd-run --user
--scope) so the process survives the gateway restart that hermes update
triggers at the end. Falls back to nohup if systemd-run is unavailable.
- Writes a marker file (.update_pending.json) with the originating
platform and chat_id before spawning the update.
- On gateway startup, _send_update_notification() checks for the marker,
reads the captured update output, sends the results back to the user,
and cleans up.
Also:
- Registers /update as a Discord slash command
- Updates README.md, docs/messaging.md, docs/slash-commands.md
- Adds 18 tests covering handler, notification, and edge cases
Fixes#163
- Add chat_topic field to SessionSource dataclass
- Update to_dict/from_dict for serialization support
- Add chat_topic parameter to build_source helper
- Extract channel.topic in Discord adapter for messages and slash commands
- Display Channel Topic in system prompt when available
- Normalize empty topics to None
- Updated the command name from `/set-home` to `/sethome` in the GatewayRunner class for consistency.
- Added a new slash command `/sethome` in the Discord adapter to set the home channel.
- Registered the `/sethome` command in the Telegram adapter to align with the updated naming convention.
- Added functionality to load values from config.yaml into the environment, allowing os.getenv() to access them.
- Ensured that existing environment variables take precedence over config values.
- Updated DiscordAdapter to resolve usernames in DISCORD_ALLOWED_USERS to numeric IDs, improving user authorization checks.
- Enhanced event handling to provide clearer logging and ensure proper synchronization of slash commands.
- Introduced new methods in run_agent.py for building API keyword arguments and normalizing assistant messages from API responses.
- Added functionality for compressing conversation context and managing session state in SQLite.
- Improved tool call execution handling, including enhanced logging and error management.
- Updated path handling in multiple platform files to utilize pathlib for better compatibility and readability.
- Updated various modules including cli.py, run_agent.py, gateway, and tools to replace silent exception handling with structured logging.
- Improved error messages to provide more context, aiding in debugging and monitoring.
- Ensured consistent logging practices throughout the codebase, enhancing traceability and maintainability.
- Introduced the `/new` command to start a new conversation, resetting the history.
- Updated command handling in the CLI and various platform adapters (Discord, Slack, Telegram) to support the new command.
- Added help command functionality to list available commands, improving user guidance.
- Enhanced command mapping for better integration across platforms, ensuring consistent command behavior.
