Telegram's Bot API only allows a specific set of emoji for bot reactions
(the ReactionEmoji enum). ✅ (U+2705) and ❌ (U+274C) are not in that
set, causing on_processing_complete reactions to silently fail with
REACTION_INVALID (caught at debug log level).
Replace with 👍 (U+1F44D) / 👎 (U+1F44E) which are always available in
Telegram's allowed reaction list. The 👀 (eyes) reaction used by
on_processing_start was already valid.
Based on the fix by @ppdng in PR #6685.

Simplified implementation of the feature from PR #6842 (RunzhouLi).
Allows Discord channels/forum threads to auto-bind skills via config:
discord:
channel_skill_bindings:
- id: "123456"
skills: ["skill-a", "skill-b"]
The run.py auto-skill loader now handles both str and list[str],
loading multiple skills in order and concatenating their payloads.
Forum threads inherit their parent channel's bindings.

Add debug logging when eyes reaction redaction fails, and add tests
for the success=False path and the no-pending-reaction edge case.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The on_processing_complete handler was never removing the eyes reaction because
_send_reaction didn't return the reaction event_id.
Fix:
- _send_reaction returns Optional[str] event_id
- on_processing_start stores it in _pending_reactions dict
- on_processing_complete redacts the eyes reaction before adding completion emoji
When extra.base_url is set in the Telegram platform config, use it as
the base URL for all Telegram API requests instead of api.telegram.org.
This allows agents to route Telegram traffic through the credential
proxy, which injects the real bot token — the VM never sees it.
Also supports extra.base_file_url for file downloads (defaults to
base_url if not set separately).

Follow-up to Dusk1e's PR #7120 (Slack send_image redirect guard):
- Rename _safe_url_for_log -> safe_url_for_log (drop underscore) since
it is now imported cross-module by the Slack adapter
- Add _ssrf_redirect_guard httpx event hook to cache_image_from_url()
and cache_audio_from_url() in base.py — same pattern as vision_tools
and the Slack adapter fix
- Update url_safety.py docstring to reflect broader coverage
- Add regression tests for image/audio redirect blocking + safe passthrough
The API server's _run_agent() was not passing task_id to
run_conversation(), causing a fresh random UUID per request. This meant
every Open WebUI message spun up a new Docker container and tore it down
afterward — making persistent filesystem state impossible.
Two fixes:
1. Pass task_id="default" so all API server conversations share the same
Docker container (matching the design intent: one configured Docker
environment, always the same container).
2. Derive a stable session_id from the system prompt + first user message
hash instead of uuid4(). This stops hermes sessions list from being
polluted with single-message throwaway sessions.
Fixes#3438.
Slack may return an HTML sign-in/redirect page instead of actual media
bytes (e.g. expired token, restricted file access). This adds two layers
of defense:
1. Content-Type check in slack.py rejects text/html responses early
2. Magic-byte validation in base.py's cache_image_from_bytes() rejects
non-image data regardless of source platform
Also adds ValueError guards in wecom.py and email.py so the new
validation doesn't crash those adapters.
Closes#6829
- configure Telegram HTTPXRequest pool/timeouts with env-overridable defaults\n- use separate request/get_updates request objects to reduce pool contention\n- skip fallback-IP transport when proxy is configured (or explicitly disabled)\n\nThis mitigates recurrent pool-timeout failures during polling reconnect/bootstrap (delete_webhook).
Python assertions are stripped when running with `python -O` (optimized
mode), making them unsuitable for runtime error handling.
1. `telegram_network.py:113` — After exhausting all fallback IPs, the code
uses `assert last_error is not None` before `raise last_error`. In
optimized mode, the assert is skipped; if `last_error` is unexpectedly
None, `raise None` produces a confusing `TypeError` instead of a
meaningful error. Replace with an explicit `if` check that raises
`RuntimeError` with a descriptive message.
2. `feishu.py:975` — The `_configure_with_overrides` closure uses
`assert original_configure is not None` as a guard. While the outer
scope only installs this closure when `original_configure` is not None,
the assert would silently disappear in optimized mode. Replace with an
explicit `if` check for defensive safety.
When /background was sent during an active run, it was not in the
platform adapter's bypass list and fell through to the interrupt path
instead of spawning a parallel background task.
Add "background" to the active-session command bypass in the platform
adapter, and add an early return in the gateway runner's running-agent
guard to route /background to _handle_background_command() before it
reaches the default interrupt logic.
Fixes#6827
Legacy flat stt.model config key (from cli-config.yaml.example and older
versions) was passed as a model override to transcribe_audio() by the
gateway, bypassing provider-specific model resolution. When the provider
was 'local' (faster-whisper), this caused:
ValueError: Invalid model size 'whisper-1'
Changes:
- gateway/run.py, discord.py: stop passing model override — let
transcribe_audio() handle provider-specific model resolution internally
- get_stt_model_from_config(): now provider-aware, reads from the correct
nested section (stt.local.model, stt.openai.model, etc.); ignores
legacy flat key for local provider to prevent model name mismatch
- cli-config.yaml.example: updated STT section to show nested provider
config structure instead of legacy flat key
- config migration v13→v14: moves legacy stt.model to the correct
provider section and removes the flat key

Follow-up to cherry-picked PR #6592:
- Extract _webhook_url property to deduplicate URL construction
- Add _find_registered_webhooks() helper for reuse
- Crash resilience: check for existing registration before POSTing
(handles restart after unclean shutdown without creating duplicates)
- Accept 200-299 status range (not just 200) for webhook creation
- Unregister removes ALL matching registrations (cleans up orphaned dupes)
- Add 17 tests covering register/unregister/find/edge cases
**Problem:**
The BlueBubbles iMessage gateway was not receiving incoming messages even though:
1. BlueBubbles Server was properly configured and running
2. Hermes gateway started without errors
3. Webhook listener was started on the configured port
The root cause was that the BlueBubbles adapter only started a local webhook
listener but never registered the webhook URL with the BlueBubbles server via
the API. Without registration, the server doesn't know where to send events.
**Fix:**
1. Added _register_webhook() method that POSTs to /api/v1/webhook with the
listener URL and event types (new-message, updated-message, message)
2. Added _unregister_webhook() method for clean shutdown
3. Both methods handle the case where webhook listens on 0.0.0.0/127.0.0.1
by using 'localhost' as the external hostname
4. Fixed documentation: 'hermes gateway logs' → 'hermes logs gateway'
**API Reference:**
https://docs.bluebubbles.app/server/developer-guides/rest-api-and-webhooks
**Testing:**
- Webhook registration is now automatic when gateway starts
- Failed registration logs a warning but doesn't prevent startup
- Clean shutdown unregisters the webhook
Closes: iMessage gateway not working issue
Add Discord thread support to cron delivery and send_message_tool.
- _parse_target_ref: handle discord platform with chat_id:thread_id format
- _send_discord: add thread_id param, route to /channels/{thread_id}/messages
- _send_to_platform: pass thread_id through for Discord
- Discord adapter send(): read thread_id from metadata for gateway path
- Update tool schema description to document Discord thread targets
Cherry-picked from PR #7046 by pandacooming (maxyangcn).
Follow-up fixes:
- Restore proxy support (resolve_proxy_url/proxy_kwargs_for_aiohttp) that was
accidentally deleted — would have caused NameError at runtime
- Remove duplicate _DISCORD_TARGET_RE regex; reuse existing _TELEGRAM_TOPIC_TARGET_RE
via _NUMERIC_TOPIC_RE alias (identical pattern)
- Fix misleading test comments about Discord negative snowflake IDs
(Discord uses positive snowflakes; negative IDs are a Telegram convention)
- Rewrite misleading scheduler test that claimed to exercise home channel
fallback but actually tested the explicit platform:chat_id parsing path
The delivery tuple in webhook.py only had 5 of 14 platforms with
gateway adapters. Adds whatsapp, matrix, mattermost, homeassistant,
email, dingtalk, feishu, wecom, and bluebubbles so webhooks can
deliver to any connected platform.
Updates docs delivery options table to list all platforms.
Follow-up to cherry-picked fix from olafthiele (PR #7035).
prompt_builder.py: The `hidden_div` detection pattern uses `.*` which does not
match newlines in Python regex (re.DOTALL is not passed). An attacker can bypass
detection by splitting the style attribute across lines:
`<div style="color:red;\ndisplay: none">injected content</div>`
Replace `.*` with `[\s\S]*?` to match across line boundaries.
credential_files.py: `_load_config_files()` catches all exceptions at DEBUG level
(line 171), making YAML parse failures invisible in production logs. Users whose
credential files silently fail to mount into sandboxes have no diagnostic clue.
Promote to WARNING to match the severity pattern used by the path validation
warnings at lines 150 and 158 in the same function.
webhook.py: `_reload_dynamic_routes()` logs JSON parse failures at WARNING (line
265) but the impact — stale/corrupted dynamic routes persisting silently — warrants
ERROR level to ensure operator visibility in alerting pipelines.

dingtalk.py: The session_webhook URL from incoming DingTalk messages is POSTed to
without any origin validation (line 290), enabling SSRF attacks via crafted webhook
URLs (e.g. http://169.254.169.254/ to reach cloud metadata). Add a regex check
that only accepts the official DingTalk API origin (https://api.dingtalk.com/).
Also cap _session_webhooks dict at 500 entries with FIFO eviction to prevent
unbounded memory growth from long-running gateway instances.
api_server.py: The X-Hermes-Session-Id request header is accepted and echoed back
into response headers (lines 675, 697) without sanitization. A session ID
containing \r\n enables HTTP response splitting / header injection. Add a check
that rejects session IDs containing control characters (\r, \n, \x00).

Add DISCORD_ALLOWED_CHANNELS (env var) / discord.allowed_channels (config.yaml)
support to restrict the bot to only respond in specified channels.
When set, messages from any channel NOT in the allowed list are silently
ignored — even if the bot is @mentioned. This provides a secure default-
deny posture vs the existing ignored_channels which is default-allow.
This is especially useful when bots in other channels may create new
channels dynamically (e.g., project bots) — a blacklist requires constant
maintenance while a whitelist is set-and-forget.
Follows the same config pattern as ignored_channels and free_response_channels:
- Env var: DISCORD_ALLOWED_CHANNELS (comma-separated channel IDs)
- Config: discord.allowed_channels (string or list of channel IDs)
- Env var takes precedence over config.yaml
- Empty/unset = no restriction (backward compatible)
Files changed:
- gateway/platforms/discord.py: check allowed_channels before ignored_channels
- gateway/config.py: map discord.allowed_channels → DISCORD_ALLOWED_CHANNELS
- hermes_cli/config.py: add allowed_channels to DEFAULT_CONFIG
Two security hardening changes for the API server:
1. **Startup warning when no API key is configured.**
When `API_SERVER_KEY` is not set, all endpoints accept unauthenticated
requests. This is the default configuration, but operators may not
realize the security implications. A prominent warning at startup
makes the risk visible.
2. **Require authentication for session continuation.**
The `X-Hermes-Session-Id` header allows callers to load and continue
any session stored in state.db. Without authentication, an attacker
who can reach the API server (e.g. via CORS from a malicious page,
or on a shared host) could enumerate session IDs and read conversation
history — which may contain API keys, passwords, code, or other
sensitive data shared with the agent.
Session continuation now returns 403 when no API key is configured,
with a clear error message explaining how to enable the feature.
When a key IS configured, the existing Bearer token check already
gates access.
This is defense-in-depth: the API server is intended for local use,
but defense against cross-origin and shared-host attacks is important
since the default binding is 127.0.0.1 which is reachable from
browsers via DNS rebinding or localhost CORS.
The text batching feature routes TEXT messages through
asyncio.create_task() + asyncio.sleep(delay). Even with delay=0,
the task fires asynchronously and won't complete before synchronous
test assertions. This broke 33 tests across Discord, Matrix, and
WeCom adapters.
When _text_batch_delay_seconds is 0 (the test fixture setting),
dispatch directly to handle_message() instead of going through
the async batching path. This preserves the pre-batching behavior
for tests while keeping batching active in production (default
delay 0.6s).
Feishu already had text batching with a static 0.6s delay. This adds
adaptive delay: waits 2.0s when a chunk is near the ~4096-char split
point since a continuation is almost certain.
Tracks _last_chunk_len on each queued event to determine the delay.
Configurable via HERMES_FEISHU_TEXT_BATCH_SPLIT_DELAY_SECONDS (default 2.0).
Ref #6892
Ports the adaptive batching pattern from the Telegram adapter.
WeCom clients split messages around 4000 chars. Adaptive delay waits

* feat: API server model name derived from profile name
For multi-user setups (e.g. OpenWebUI), each profile's API server now
advertises a distinct model name on /v1/models:
- Profile 'lucas' -> model ID 'lucas'
- Profile 'admin' -> model ID 'admin'
- Default profile -> 'hermes-agent' (unchanged)
Explicit override via API_SERVER_MODEL_NAME env var or
platforms.api_server.model_name config for custom names.
Resolves friction where OpenWebUI couldn't distinguish multiple
hermes-agent connections all advertising the same model name.
* docs: multi-user setup with profiles for API server + Open WebUI
- api-server.md: added Multi-User Setup section, API_SERVER_MODEL_NAME
to config table, updated /v1/models description
- open-webui.md: added Multi-User Setup with Profiles section with
step-by-step guide, updated model name references
- environment-variables.md: added API_SERVER_MODEL_NAME entry
Follow-up improvements on top of the shared resolver from PR #6562:
- Add platform_env_var parameter to resolve_proxy_url() so DISCORD_PROXY
takes priority over generic HTTPS_PROXY/ALL_PROXY env vars
- Add SOCKS proxy support via aiohttp_socks.ProxyConnector with rdns=True
(critical for GFW/Shadowrocket/Clash users — issue #6649)
- proxy_kwargs_for_bot() returns connector= for SOCKS, proxy= for HTTP
- proxy_kwargs_for_aiohttp() returns split (session_kw, request_kw) for
standalone aiohttp sessions
- Add proxy support to send_message_tool.py (Discord REST, Slack, SMS)
for cron job delivery behind proxies (from PR #2208)
- Add proxy support to Discord image/document downloads
- Fix duplicate import sys in base.py
- Add resolve_proxy_url() to base.py — shared by all platform adapters
- Check HTTPS_PROXY / HTTP_PROXY / ALL_PROXY env vars first
- Fall back to macOS system proxy via scutil --proxy (zero-config)
- Pass proxy= to discord.py commands.Bot() for gateway connectivity
- Refactor telegram_network.py to use shared resolver
- Update test fixtures to accept proxy kwarg
- Add _ThreadContextCache dataclass for caching fetched context (60s TTL)
- Add exponential backoff retry for conversations.replies 429 rate limits
(Tier 3, ~50 req/min)
- Only fetch context when no active session exists (guard at call site)
to prevent duplication across turns
- Hoist bot_uid lookup outside the per-message loop
- Clearer header text for injected thread context
Based on PR #6162 by jarvisxyz, cherry-picked onto current main.
- Treat mpim (multi-party IM / group DM) channels as DMs — no @mention
required, continuous session like 1:1 DMs
- Only add 👀/✅ reactions when bot is directly addressed (DM or
@mention). In listen-all channels (require_mention=false) reacting
to every message would be noisy.
Based on PR #4633 by gunpowder-client-vm, adapted to current main.
Three modes: "none" (default, backward-compatible), "mentions" (accept
bot messages only when they @mention us), "all" (accept all bot messages

Or env var: SLACK_ALLOW_BOTS=mentions
Self-message guard always active regardless of mode.

- Replace hardcoded mention check with configurable gating logic
- Bridge slack config.yaml settings to env vars
- Bridge free_response_channels through the generic platform bridging loop
- Add 26 tests covering config parsing, env fallback, gating logic
Config usage:

Approval button clicks (Block Kit actions in Slack, CallbackQuery in
Telegram) bypass the normal message authorization flow in gateway/run.py.
Any workspace/group member who can see the approval message could click
Approve to authorize dangerous commands.
Read SLACK_ALLOWED_USERS / TELEGRAM_ALLOWED_USERS env vars directly in
the approval handlers. When an allowlist is configured and the clicking
user is not in it, the click is silently ignored (Slack) or answered
with an error (Telegram). Wildcard '*' permits all users. When no
allowlist is configured, behavior is unchanged (open access).
Based on the idea from PR #6735 by maymuneth, reimplemented to use the
existing env-var-based authorization system rather than a nonexistent
_allowed_user_ids adapter attribute.
1. gateway/platforms/slack.py: Replace check-then-set TOCTOU race on
_approval_resolved with atomic dict.pop(). Two concurrent button
clicks could both pass the guard before either set it to True,
causing double resolve_gateway_approval — which can resolve the
WRONG queued approval when multiple are pending for the same session.
2. hermes_state.py: Add WARNING log and proper fallbacks when
json.loads fails on tool_calls (→ []), reasoning_details (→ None),
and codex_reasoning_items (→ None). Previously, failures were
silently swallowed: tool_calls stayed as a raw string (iterating
yields characters, not objects), and reasoning fields were simply
missing from the dict.

Prevents unbounded memory growth in _assistant_threads dict.
Evicts oldest entries when exceeding _ASSISTANT_THREADS_MAX (5000),
matching the pattern used by _mentioned_threads and _seen_messages.
When a background process with notify_on_complete=True finishes, the
gateway injects a synthetic MessageEvent to notify the session. This
event was constructed without user_id, causing _is_user_authorized()
to reject it and — for DM-origin sessions — trigger the pairing flow,
sending "Hi~ I don't recognize you yet!" with a pairing code to the
chat owner.
Add an `internal` flag to MessageEvent that bypasses authorization
checks for system-generated synthetic events. Only the process watcher
sets this flag; no external/adapter code path can produce it.
Includes 4 regression tests covering the fix and the normal pairing path.
ORIGINAL INCIDENT:
Discord forum descriptions (the topic field on ForumChannel) were invisible
to the agent. When a user set project instructions in a forum's description
(e.g. tool-evaluations), threads created in that forum had no Channel Topic
in their session context. Discovered while evaluating per-forum auto-context
injection for web-tap-terminal development threads.
ISSUE IN THE CODE:
In gateway/platforms/discord.py, all three session entry points
(_handle_message, _build_slash_event, _dispatch_thread_session) read
chat_topic via getattr(channel, 'topic', None). Discord Thread objects
don't carry a topic — only the parent ForumChannel does. So chat_topic
was always None for forum threads, and the Channel Topic line was never
injected into build_session_context_prompt output. The infrastructure to
handle this was already in place — _is_forum_parent() detects forum
channels, _format_thread_chat_name() traverses to the parent, and
build_session_context_prompt() renders Channel Topic when present. The
forum parent was being identified; its topic just wasn't being read.
HOW THIS COMMIT FIXES IT:
Adds _get_effective_topic(channel, is_thread) helper that reads
channel.topic first, then falls back to the parent forum's topic when
the channel is a thread inside a forum. All three session entry points
now call this helper instead of inlining getattr(channel, 'topic', None).
Existing tests pass unchanged.

Fixes#4647 — Signal replies duplicated when gateway streaming is enabled.
Root cause: stream_consumer.py did not handle the case where send() returns
success=True but no message_id (Signal behavior). Every stream delta produced
a separate send() call (7+ messages instead of 2), plus the gateway sent
another full duplicate since already_sent was never set.
Changes:
- stream_consumer.py: Add elif branch for success-without-message_id — enters
fallback mode (sets already_sent, disables editing, sends only continuation)
- signal.py send(): Extract timestamp from signal-cli RPC result as message_id
so stream consumer follows normal edit→fallback path
- signal.py: Add public stop_typing() delegating to _stop_typing_indicator()
so base adapter's _keep_typing finally block can clean up typing tasks
- gateway/run.py: Per-platform tool_progress_overrides (#6164) — lets users
set e.g. signal: off while keeping telegram: all
- hermes_cli/config.py: Add tool_progress_overrides to DEFAULT_CONFIG
