Background review notifications ("💾 Skill created", "💾 Memory updated")
could race ahead of the main assistant reply in chat, making it look like
the agent stopped after creating a skill.
Gate bg-review notifications behind a threading.Event + pending queue.
Register a release callback on the adapter's _post_delivery_callbacks dict
so base.py's finally block fires it after the main response is delivered.
The queued-message path in _run_agent pops and calls the callback directly
to prevent double-fire.

Extract resolve_channel_prompt() shared helper into
gateway/platforms/base.py. Refactor Discord to use it.
Wire channel_prompts into Telegram (groups + forum topics),
Slack (channels), and Mattermost (channels).
Config bridging now applies to all platforms (not just Discord).
Added channel_prompts defaults to telegram/slack/mattermost
config sections.
Docs added to all four platform pages with platform-specific
examples (topic inheritance for Telegram, channel IDs for Slack,
etc.).
Move _ensure_discord_mock() from module level to _make_adapter() so it
doesn't poison sys.modules for other discord test files. Use
types.ModuleType instead of MagicMock for the mock module to avoid
auto-generated __file__ attribute confusing hasattr checks.
Add BrennerSpear to AUTHOR_MAP.
- Remove double str() normalization in _resolve_channel_prompt since
config bridging already handles numeric YAML key conversion
- Remove dead prompts.get(str(key)) fallback that could never match
after keys were already normalized to strings
- Replace getattr(event, "channel_prompt", None) with direct attribute
access since channel_prompt is a declared dataclass field
- Update test to verify normalization responsibility lives in config bridging
_parse_session_key() blindly assigned parts[5] as thread_id for all
chat types. For group sessions with per-user isolation, parts[5] is
a user_id, not a thread_id. This could cause shutdown notifications
to route with incorrect thread metadata.
Only return thread_id for chat types where the 6th element is
unambiguous: dm and thread. For group/channel sessions, omit
thread_id since the suffix may be a user_id.
Based on the approach from PR #9938 by @Ruzzgar.
After clear_session_vars() reset contextvars to their default (''),
get_session_env() treated the empty string as falsy and fell through
to os.environ — resurrecting stale HERMES_SESSION_* values from CLI
startup, cron, or previous sessions. This broke session isolation
in the gateway where concurrent messages could see each other's
stale environment values.
Fix: use a sentinel (_UNSET) as the contextvar default instead of ''.
get_session_env() now checks 'value is not _UNSET' instead of
truthiness. Three states are cleanly distinguished:
- _UNSET (never set): fall back to os.environ (CLI/cron compat)
- '' (explicitly cleared): return '' — no os.environ fallback
- 'telegram' (actively set): return the value
clear_session_vars() now uses var.set('') instead of var.reset(token)
to mark vars as explicitly cleared rather than reverting to _UNSET.
Closes#10304
When a model (e.g. mimo-v2-pro) streams intermediate text alongside tool
calls ("Let me search for that") but then returns empty after processing
tool results, the stream consumer already_sent flag is True from the
earlier text delivery. The gateway suppression check
(already_sent=True, failed=False → return None) would swallow the final
response, leaving the user staring at silence after the search.
Two changes:
1. gateway/run.py return path: skip already_sent suppression when the
final_response is "(empty)" or empty — the user needs to know the
agent finished even if streaming sent partial content earlier.
2. gateway/run.py response handler: convert the internal "(empty)"
sentinel to a user-friendly warning instead of delivering the raw
sentinel string.
Tests added for all empty/None/sentinel cases plus preserved existing
suppression behavior for normal non-empty responses.
Discord's _register_slash_commands() had a hardcoded list of ~27 commands
while COMMAND_REGISTRY defines 34+ gateway-available commands. Missing
commands (debug, branch, rollback, snapshot, profile, yolo, fast, reload,
commands) were invisible in Discord's / autocomplete — users couldn't
discover them.
Add a dynamic catch-all loop after the explicit registrations that
iterates COMMAND_REGISTRY, skips already-registered commands, and
auto-registers the rest using discord.app_commands.Command(). Commands
with args_hint get an optional string parameter; parameterless commands
get a simple callback.
This ensures any future commands added to COMMAND_REGISTRY automatically
appear on Discord without needing a manual entry in discord.py.
Telegram and Slack already derive dynamically from COMMAND_REGISTRY
via telegram_bot_commands() and slack_subcommand_map() — no changes
needed there.
Two gateway fixes:
1. MessageDeduplicator.is_duplicate() now checks TTL at query time (#10306)
Previously, is_duplicate() returned True for any previously seen ID
without checking its age — expired entries were only purged when cache
size exceeded max_size. On normal workloads that never overflow, message
IDs stayed deduplicated forever instead of expiring after the TTL.
Fix: check `now - timestamp < ttl` before returning True. Expired
entries are removed and treated as new messages.
2. Gateway --config flag now uses yaml.safe_load() (#10216)
The --config CLI flag in gateway/run.py main() used json.load() to
parse config files. YAML is the only documented config format and
every other config loader uses yaml.safe_load(). A YAML config file
passed via --config would crash with json.JSONDecodeError.
Closes#10306Closes#10216
_parse_session_key() now extracts the optional 6th part (thread_id) from
session keys, and _notify_active_sessions_of_shutdown uses _parsed.get()
instead of the removed 'parts' variable. Without this, shutdown notifications
silently failed (NameError caught by try/except) and forum topic routing
was lost.
- Populate watcher_* routing fields for watch-only processes (not just
notify_on_complete), so watch-pattern events carry direct metadata
instead of relying solely on session_key parsing fallback
- Extract _parse_session_key() helper to dedupe session key parsing
at two call sites in gateway/run.py
- Add negative test proving cross-thread leakage doesn't happen
- Add edge-case tests for _build_process_event_source returning None
(empty evt, invalid platform, short session_key)
- Add unit tests for _parse_session_key helper
Three fixes for the duplicate reply bug affecting all gateway platforms:
1. base.py: Suppress stale response when the session was interrupted by a
new message that hasn't been consumed yet. Checks both interrupt_event
and _pending_messages to avoid false positives. (#8221, #2483)
2. run.py (return path): Remove response_previewed guard from already_sent
check. Stream consumer's already_sent alone is authoritative — if
content was delivered via streaming, the duplicate send must be
suppressed regardless of the agent's response_previewed flag. (#8375)
3. run.py (queued-message path): Same fix — already_sent without
response_previewed now correctly marks the first response as already
streamed, preventing re-send before processing the queued message.
The response_previewed field is still produced by the agent (run_agent.py)
but is no longer required as a gate for duplicate suppression. The stream
consumer's already_sent flag is the delivery-level truth about what the
user actually saw.
Concepts from PR #8380 (konsisumer). Closes#8375, #8221, #2483.
When a user sends a message while the agent is executing a task on the
gateway, the agent is now interrupted immediately — not silently queued.
Previously, messages were stored in _pending_messages with zero feedback
to the user, potentially leaving them waiting 1+ hours.
Root cause: Level 1 guard (base.py) intercepted all messages for active
sessions and returned with no response. Level 2 (gateway/run.py) which
calls agent.interrupt() was never reached.
Fix: Expand _handle_active_session_busy_message to handle the normal
(non-draining) case:
1. Call running_agent.interrupt(text) to abort in-flight tool calls
and exit the agent loop at the next check point
2. Store the message as pending so it becomes the next turn once the
interrupted run returns
3. Send a brief ack: 'Interrupting current task (10 min elapsed,
iteration 21/60, running: terminal). I'll respond shortly.'
4. Debounce acks to once per 30s to avoid spam on rapid messages
Reported by @Lonely__MH.
The /v1/responses endpoint generated a new UUID session_id for every
request, even when previous_response_id was provided. This caused each
turn of a multi-turn conversation to appear as a separate session on the
web dashboard, despite the conversation history being correctly chained.
Fix: store session_id alongside the response in the ResponseStore, and
reuse it when a subsequent request chains via previous_response_id.
Applies to both the non-streaming /v1/responses path and the streaming
SSE path. The /v1/runs endpoint also gains session continuity from
stored responses (explicit body.session_id still takes priority).
Adds test verifying session_id is preserved across chained requests.
The streaming path emits output as content-part arrays for Open WebUI
compatibility, but the batch (non-streaming) Responses API path must
return output as a plain string per the OpenAI Responses API spec.
Reverts the _extract_output_items change from the cherry-picked commits
while preserving the streaming path's array format.
When a session gets stuck (hung terminal, runaway tool loop) and the
user restarts the gateway, the same session history loads and puts the
agent right back in the stuck state. The user is trapped in a loop:
restart → stuck → restart → stuck.
Fix: track restart-failure counts per session using a simple JSON file
(.restart_failure_counts). On each shutdown with active agents, the
counter increments for those sessions. On startup, if any session has
been active across 3+ consecutive restarts, it's auto-suspended —
giving the user a clean slate on their next message.
The counter resets to 0 when a session completes a turn successfully
(response delivered), so normal sessions that happen to be active
during planned restarts (/restart, hermes update) won't accumulate
false counts.
Implementation:
- _increment_restart_failure_counts(): called during stop() when
agents are active. Writes {session_key: count} to JSON file.
Sessions NOT active are dropped (loop broken).
- _suspend_stuck_loop_sessions(): called on startup. Reads the file,
suspends sessions at threshold (3), clears the file.
- _clear_restart_failure_count(): called after successful response
delivery. Removes the session from the counter file.
No SessionEntry schema changes. No database migration. Pure file-based
tracking that naturally cleans up.
Test plan:
- 9 new stuck-loop tests (increment, accumulate, threshold, clear,
suspend, file cleanup, edge cases)
- All 28 gateway lifecycle tests pass (restart drain + auto-continue
+ stuck loop)
When the gateway restarts mid-agent-work, the session transcript ends
on a tool result the agent never processed. Previously, the user had
to type 'continue' or use /retry (which replays from scratch, losing
all prior work).
Now, when the next user message arrives and the loaded history ends
with role='tool', a system note is prepended:
[System note: Your previous turn was interrupted before you could
process the last tool result(s). Please finish processing those
results and summarize what was accomplished, then address the
user's new message below.]
This is injected in _run_agent()'s run_sync closure, right before
calling agent.run_conversation(). The agent sees the full history
(including the pending tool results) and the system note, so it can
summarize what was accomplished and then handle the user's new input.
Design decisions:
- No new session flags or schema changes — purely detects trailing
tool messages in the loaded history
- Works for any restart scenario (clean, crash, SIGTERM, drain timeout)
as long as the session wasn't suspended (suspended = fresh start)
- The user's actual message is preserved after the note
- If the session WAS suspended (unclean shutdown), the old history is
abandoned and the user starts fresh — no false auto-continue
Also updates the shutdown notification message from 'Use /retry after
restart to continue' to 'Send any message after restart to resume
where it left off' — which is now accurate.
Test plan:
- 6 new auto-continue tests (trailing tool detection, no false
positives for assistant/user/empty history, multi-tool, message
preservation)
- All 13 restart drain tests pass (updated /retry assertion)
Instead of consuming one top-level slash command slot per skill (hitting the
100-command limit with ~26 built-ins + 74 skills), skills are now organized
under a single /skill group command with category-based subcommand groups:
/skill creative ascii-art [args]
/skill media gif-search [args]
/skill mlops axolotl [args]
Discord supports 25 subcommand groups × 25 subcommands = 625 max skills,
well beyond the previous 74-slot ceiling.
Categories are derived from the skill directory structure:
- skills/creative/ascii-art/ → category 'creative'
- skills/mlops/training/axolotl/ → category 'mlops' (top-level parent)
- skills/dogfood/ → uncategorized (direct subcommand)
Changes:
- hermes_cli/commands.py: add discord_skill_commands_by_category() with
category grouping, hub/disabled filtering, Discord limit enforcement
- gateway/platforms/discord.py: replace top-level skill registration with
_register_skill_group() using app_commands.Group hierarchy
- tests: 7 new tests covering group creation, category grouping,
uncategorized skills, hub exclusion, deep nesting, empty skills,
and handler dispatch
Inspired by Discord community suggestion from bottium.
- TestHealthDetailedEndpoint: 3 tests for the new API server endpoint
(returns runtime data, handles missing status, no auth required)
- TestProbeGatewayHealth: 5 tests for _probe_gateway_health()
(URL normalization, successful/failed probes, fallback chain)
- TestStatusRemoteGateway: 4 tests for /api/status remote fallback
(remote probe triggers, skipped when local PID found, null PID handling)
Feishu approval clicks need the resolved card to come back from the
synchronous callback path itself. Leaving approval resolution to the
generic asynchronous card-action flow made button feedback depend on
later loop work instead of the callback response the client is waiting
for.
Change-Id: I574997cbbcaa097fdba759b47367e28d1b56b040
Constraint: Feishu card-action callbacks must acknowledge quickly and reflect final approval state from the callback response path
Rejected: Keep approval handling on the generic async card-action route | leaves card state synchronization vulnerable to callback timing and follow-up update ordering
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep approval callback response construction separate from async queue unblocking unless Feishu callback semantics change
Tested: pytest tests/gateway/test_feishu.py tests/gateway/test_feishu_approval_buttons.py tests/gateway/test_approve_deny_commands.py tests/gateway/test_slack_approval_buttons.py tests/gateway/test_telegram_approval_buttons.py -q
Not-tested: Live Feishu workspace end-to-end callback rendering
Three fixes for gateway lifecycle stability:
1. Notify active sessions before shutdown (#new)
When the gateway receives SIGTERM or /restart, it now sends a
notification to every chat with an active agent BEFORE starting
the drain. Users see:
- Shutdown: 'Gateway shutting down — your task will be interrupted.'
- Restart: 'Gateway restarting — use /retry after restart to continue.'
Deduplicates per-chat so group sessions with multiple users get
one notification. Best-effort: send failures are logged and swallowed.
2. Skip .clean_shutdown marker when drain timed out
Previously, a graceful SIGTERM always wrote .clean_shutdown, even if
agents were force-interrupted when the drain timed out. This meant
the next startup skipped session suspension, leaving interrupted
sessions in a broken state (trailing tool response, no final message).
Now the marker is only written if the drain completed without timeout,
so interrupted sessions get properly suspended on next startup.
3. Post-restart health check for hermes update (#6631)
cmd_update() now verifies the gateway actually survived after
systemctl restart (sleep 3s + is-active check). If the service
crashed immediately, it retries once. If still dead, prints
actionable diagnostics (journalctl command, manual restart hint).
Also closes#8104 — already fixed on main (the /restart handler
correctly detects systemd via INVOCATION_ID and uses via_service=True).
Test plan:
- 6 new tests for shutdown notifications (dedup, restart vs shutdown
messaging, sentinel filtering, send failure resilience)
- Existing restart drain + update tests pass (47 total)
Follow-up for cherry-picked PR #9746 — three pre-existing tests used
adapter._webhook_url (bare URL) in mock data, but _register_webhook
and _unregister_webhook now compare against _webhook_register_url
(password-bearing URL). Updated to match.
When BlueBubbles posts webhook events to the adapter, it uses the exact
URL registered via /api/v1/webhook — and BB's registration API does not
support custom headers. The adapter currently registers the bare URL
(no credentials), but then requires password auth on inbound POSTs,
rejecting every webhook with HTTP 401.
This is masked on fresh BB installs by a race condition: the webhook
might register once with a prior (possibly patched) URL and keep working
until the first restart. On v0.9.0, _unregister_webhook runs on clean
shutdown, so the next startup re-registers with the bare URL and the
401s begin. Users see the bot go silent with no obvious cause.
Root cause: there's no way to pass auth credentials from BB to the
webhook handler except via the URL itself. BB accepts query params and
preserves them on outbound POSTs.
## Fix
Introduce `_webhook_register_url` — the URL handed to BB's registration
API, with the configured password appended as a `?password=<value>`
query param. The existing webhook auth handler already accepts this
form (it reads `request.query.get("password")`), so no change to the
receive side is needed.
The bare `_webhook_url` is still used for logging and for binding the
local listener, so credentials don't leak into log output. Only the
registration/find/unregister paths use the password-bearing form.
## Notes
- Password is URL-encoded via urllib.parse.quote, handling special
characters (&, *, @, etc.) that would otherwise break parsing.
- Storing the password in BB's webhook table is not a new disclosure:
anyone with access to that table already has the BB admin password
(same credential used for every other API call).
- If `self.password` is empty (no auth configured), the register URL
is the bare URL — preserves current behavior for unauthenticated
local-only setups.

BlueBubbles v1.9+ webhook payloads for new-message events do not always
include a top-level chatGuid field on the message data object. Instead,
the chat GUID is nested under data.chats[0].guid.
The adapter currently checks five top-level fallback locations (record and
payload, snake_case and camelCase, plus payload.guid) but never looks
inside the chats array. When none of those top-level fields contain the
GUID, the adapter falls through to using the sender's phone/email as the
session chat ID.
This causes two observable bugs when a user is a participant in both a DM
and a group chat with the bot:
1. DM and group sessions merge. Every message from that user ends up with
the same session_chat_id (their own address), so the bot cannot
distinguish which thread the message came from.
2. Outbound routing becomes ambiguous. _resolve_chat_guid() iterates all
chats and returns the first one where the address appears as a
participant; group chats typically sort ahead of DMs by activity, so
replies and cron messages intended for the DM can land in a group.
This was observed in production: a user's morning brief cron delivered to
a group chat with his spouse instead of his DM thread.
The fix adds a single fallback that extracts chat_guid from
record["chats"][0]["guid"] when the top-level fields are empty. The chats
array is included in every new-message webhook payload in BB v1.9.9
(verified against a live server). It is backwards compatible: if a future
BB version starts including chatGuid at the top level, that still wins.

When GATEWAY_PROXY_URL (or gateway.proxy_url in config.yaml) is set,
the gateway becomes a thin relay: it handles platform I/O (encryption,
threading, media) and delegates all agent work to a remote Hermes API
server via POST /v1/chat/completions with SSE streaming.
This enables the primary use case of running a Matrix E2EE gateway in
Docker on Linux while the actual agent runs on the host (e.g. macOS)
with full access to local files, memory, skills, and a unified session
store. Works for any platform adapter, not just Matrix.
Configuration:
- GATEWAY_PROXY_URL env var (Docker-friendly)
- gateway.proxy_url in config.yaml
- GATEWAY_PROXY_KEY env var for API auth (matches API_SERVER_KEY)
- X-Hermes-Session-Id header for session continuity
Architecture:
- _get_proxy_url() checks env var first, then config.yaml
- _run_agent_via_proxy() handles HTTP forwarding with SSE streaming
- _run_agent() delegates to proxy path when URL is configured
- Platform streaming (GatewayStreamConsumer) works through proxy
- Returns compatible result dict for session store recording
Files changed:
- gateway/run.py: proxy mode implementation (~250 lines)
- hermes_cli/config.py: GATEWAY_PROXY_URL + GATEWAY_PROXY_KEY env vars
- tests/gateway/test_proxy_mode.py: 17 tests covering config
resolution, dispatch, HTTP forwarding, error handling, message
filtering, and result shape validation
Closes discussion from Cars29 re: Matrix gateway mixed-mode issue.
During rapid tool-calling, the model often emits 1-2 tokens before
switching to tool calls. The stream consumer would create a new message
with 'X ▉' (short text + cursor), and if the follow-up edit to strip
the cursor was rate-limited by the platform, the cursor remained as
a permanent standalone message — reported on Telegram as 'white box'
artifacts.
Add a minimum-content guard in _send_or_edit: when creating a new
standalone message (no existing message_id), require at least 4
visible characters alongside the cursor before sending. Shorter text
accumulates into the next streaming segment instead.
This prevents cursor-only 'tofu' messages across all platforms without
affecting normal streaming (edits to existing messages, final sends
without cursor, and messages with substantial text are all unaffected).

- Restore missing _setup_signal/email/sms/dingtalk/feishu/wecom/wecom_callback
functions that were lost during the original merge
Models like MiniMax emit inline <think>...</think> reasoning blocks in
their content field. The CLI already suppresses these via a state machine
in _stream_delta, but the gateway's GatewayStreamConsumer had no
equivalent filtering — raw think blocks were streamed directly to
Discord/Telegram/Slack.
The fix adds a _filter_and_accumulate() method that mirrors the CLI's
approach: a state machine tracks whether we're inside a reasoning block
and silently discards the content. Includes the same block-boundary
check (tag must appear at line start or after whitespace-only prefix)
to avoid false positives when models mention <think> in prose.
Handles all tag variants: <think>, <thinking>, <THINKING>, <thought>,
<reasoning>, <REASONING_SCRATCHPAD>.
Also handles edge cases:
- Tags split across streaming deltas (partial tag buffering)
- Unclosed blocks (content suppressed until stream ends)
- Multiple consecutive blocks
- _flush_think_buffer on stream end for held-back partial tags
Adds 22 unit tests + 1 integration test covering all scenarios.
When the 5-second stream_task timeout in gateway/run.py expires (due to
slow Telegram API calls from rate limiting after several messages), the
stream consumer is cancelled via asyncio.CancelledError. The
CancelledError handler did a best-effort final edit but never set
final_response_sent, so the gateway fell through to the normal send path
and delivered the full response again as a reply — causing a duplicate.
The fix: in the CancelledError handler, set final_response_sent = True
when already_sent is True (i.e., the stream consumer had already
delivered content to the user). This tells the gateway's already_sent
check that the response was delivered, preventing the duplicate send.
Adds two tests verifying the cancellation behavior:
- Cancelled with already_sent=True → final_response_sent=True (no dup)
- Cancelled with already_sent=False → final_response_sent=False (normal
send path proceeds)
Reported by community user hume on Discord.
/stop was calling suspend_session() which marked the session for auto-reset
on the next message. This meant users lost their conversation history every
time they stopped a running agent — especially painful for untitled sessions
that can't be resumed by name.
Now /stop just interrupts the agent and cleans the session lock. The session
stays intact so users can continue the conversation.
The suspend behavior was introduced in #7536 to break stuck session resume
loops on gateway restart. That case is already handled by
suspend_recently_active() which runs at gateway startup, so removing it from
/stop doesn't regress the original fix.
Updated the acquire_scoped_lock function to treat empty or corrupt lock files as stale. This change ensures that if a lock file exists but is invalid, it will be removed to prevent issues with stale locks. Added tests to verify recovery from both empty and corrupt lock files.
