Extends the existing channel_skill_bindings mechanism (previously
Discord-only) to Slack, so a channel or DM can auto-load one or more
skills at session start without relying on the model's skill selector
for every short reply.
Motivation: Mats's German flashcards DM pushes a cron-driven card
5x/day; he responds with one-word guesses like 'work'. Previously each
reply required the main agent to decide whether to load german-flashcards
(full opus turn just to pick a skill). With the binding configured per
Slack channel, the skill is injected at session start and grading runs
directly.
Changes:
- Extract resolve_channel_skills() from DiscordAdapter._resolve_channel_skills
into gateway.platforms.base (now shared across adapters).
- DiscordAdapter._resolve_channel_skills delegates to the shared helper
(behavior preserved — existing test suite still passes unchanged).
- SlackAdapter: resolve channel_skill_bindings on each message and attach
auto_skill to MessageEvent. gateway/run.py already handles auto-skill
injection on new sessions; this just wires Slack through it.
- gateway/config.py: accept channel_skill_bindings in slack: block of
config.yaml (was Discord-only).
- Tests: new tests/gateway/test_slack_channel_skills.py with 11 cases
covering DM/thread/parent resolution, single-vs-list skills, dedup,
malformed entries. Discord suite unchanged.
- Docs: add 'Per-Channel Skill Bindings' section to Slack user guide.
Config example:
slack:
channel_skill_bindings:
- id: "D0ATH9TQ0G6"
skills: ["german-flashcards"]
Multiple overlapping Slack attachment improvements:
1. Upload retry with backoff on transient errors (429, 5xx, connection
reset, rate_limited, service unavailable). New _is_retryable_upload_error
helper covers three upload paths: _upload_file, send_video,
send_document. Up to 3 attempts with 1.5s * attempt backoff.
2. Thread participation tracking: successful file uploads now add the
thread_ts to _bot_message_ts, mirroring how text replies are tracked.
This lets follow-up thread messages auto-trigger the bot (same
engagement rules as replied threads).
3. Thread metadata preservation in the image redirect-guard fallback
(send_image → send text fallback) and in two gateway.run.py send
paths (image + document fallback calls).
4. HTML response rejection in _download_slack_file_bytes. Parallels
the existing check in _download_slack_file. Guards against Slack
returning a sign-in / redirect page as document bytes when scopes
are missing, so the agent doesn't get HTML-as-a-PDF.
5. File lifecycle event acks (file_shared / file_created / file_change).
These events arrive around snippet uploads. Acking them silences the
slack_bolt 'Unhandled request' 404 warnings without changing behavior.
6. Post-loop message type classification so a mixed image+document upload
classifies as PHOTO (or VOICE if no image), falling back to DOCUMENT.
Previously, the per-file classification in the inbound loop could be
overwritten unpredictably.
7. Expanded text-inject whitelist in inbound document handling to cover
.csv, .json, .xml, .yaml, .yml, .toml, .ini, .cfg (up to 100KB) so
snippets and config files are directly visible to the agent, not just
cached as opaque uploads. Paired with new MIME entries in
SUPPORTED_DOCUMENT_TYPES in base.py.
Squashed from two commits in #11819 so the single commit carries the
contributor's GitHub attribution (the original commits were authored
under a local dev hostname).
Slack's modern composer sends messages with a 'blocks' array that
contains rich_text elements. When a user forwards or quotes another
message, the quoted content shows up in the rich_text_quote children
of that array — and is NOT included in the plain 'text' field. The
agent saw only the lossy plain text and was blind to forwarded /
quoted content. Same story for link unfurl previews (Notion, docs,
GitHub, etc.) which Slack puts in the 'attachments' array.
Two fixes in the inbound handler:
1. _extract_text_from_slack_blocks walks rich_text / rich_text_quote /
rich_text_list / rich_text_preformatted trees and renders readable
text ('> quoted', '• bullet', code fences), dedupes against the
plain text field, and appends the extracted content so the agent
sees everything.
2. Link unfurl / attachment preview extraction reads title, url,
body, and footer from the 'attachments' array and appends a
'📎 [title](url)\n body\n _footer_' section per preview.
Skips is_msg_unfurl to avoid echoing our own Slack replies back.
Routing is careful not to trust augmented text: mention gating
(is_mentioned) and slash-command detection both run against the
original 'text' field, so forwarded content containing '<@bot>' or
'/deploy' in a quote can't trick the bot into responding in a
channel it shouldn't or classifying a normal message as a command.
Adjustment from original PR: dropped _serialize_slack_blocks_for_agent,
which inlined a redacted JSON dump of non-rich_text blocks (section,
accessory, actions, etc.) — the agent would see the raw Block Kit
structure for UI-heavy alerts. It added up to 6000 characters to the
prompt context on every qualifying message with no opt-out. The
rich_text extraction and attachment unfurls cover the common bug-fix
case (quoted/forwarded content + link previews) without the prefill
tax. If a user needs block inspection later, it can return as a
config opt-in.
Also updates the Slack platform notes in session.py to accurately
describe what the gateway inlines.
Translate Slack attachment failures into actionable user-facing notices
instead of generic download errors. When a scope/auth/permission issue
breaks attachment processing, the user sees:
[Slack attachment notice]
- Slack attachment access failed for photo.jpg. Missing scope:
files:read. Update the Slack app scopes/settings and reinstall
the app to the workspace.
Two helpers do the translation:
_describe_slack_api_error — handles SlackApiError responses
(missing_scope, invalid_auth, file_not_found, access_denied, etc.)
_describe_slack_download_failure — handles httpx.HTTPStatusError
(401/403/404) and Slack-returns-HTML-sign-in fallbacks
Wired into three existing call sites:
- the Slack Connect files.info path (PR #11111) so scope errors
surface instead of being logged as generic "files.info failed"
- the image, audio, and document download paths so 401/403 and
HTML-body responses translate into actionable notices
Adjustment from original PR: dropped _probe_slack_file_access_issue,
the proactive pre-download files.info probe. It added one extra
Slack API call per attachment even on healthy ones, and overlapped
with the existing files.info call from PR #11111. The post-failure
translation path covers the same user-facing diagnostic value
without the per-message tax.
Also documents files:read scope more prominently in the Slack setup
guide and troubleshooting table.

Slack Connect channels return file objects with file_access="check_file_info"
and no url_private_download field (see
https://docs.slack.dev/reference/objects/file-object/#slack_connect_files).
These stub objects must be resolved via files.info before download can
proceed. Without this the agent silently skips attachments posted in
Slack Connect channels.
Call files.info on every file whose file_access is check_file_info,
replace the stub with the full file object, and let the existing
download path continue. Warn and skip on files.info failures.
Closes#11095.
The Slack thread-context fetcher used to drop every message with a
bot_id, which silently erased the thread parent whenever a cron job (or
any other bot) had posted it. As a result, replies to a cron-posted
summary lost all context and the agent answered as if from a blank
thread.
Changes:
1. gateway/platforms/slack.py::_fetch_thread_context
- Keep the thread parent even when it was posted by a bot
(e.g. cron summaries, third-party integrations).
- Only skip *our own* prior bot replies to avoid circular context,
matching the per-workspace bot user id via _team_bot_user_ids so
multi-workspace deployments stay correct.
- Keep non-self bot children (useful third-party context).
2. gateway/platforms/slack.py::_handle_slack_message
- Populate MessageEvent.reply_to_text for thread replies (parity
with Telegram/Discord/Feishu/WeCom). gateway.run uses this field
to inject a [Replying to: "..."] prefix when the parent is not
already in the session history, which is exactly the scenario
triggered by cron-generated thread parents.
- New helper _fetch_thread_parent_text reuses the existing thread-
context cache (and its 60s TTL) to avoid duplicate
conversations.replies calls; falls back to a cheap limit=1 fetch
when the cache is cold.
Tests:
- Updated TestSlackThreadContext::test_skips_bot_messages to reflect
the new behaviour (self-bot child dropped, third-party bot kept).
- Added:
* test_fetch_thread_context_includes_bot_parent
* test_fetch_thread_context_excludes_self_bot_replies
* test_fetch_thread_context_multi_workspace
* test_fetch_thread_context_current_ts_excluded (regression guard)
* test_fetch_thread_parent_text_from_cache
* test_slack_reply_to_text_set_on_thread_reply
* test_slack_reply_to_text_none_for_top_level_message
Full Slack suite: 176 passed (was 169).
Extends the strict_mention feature so an @mention in strict mode no
longer persistently tags the thread as 'mentioned'. Without this, the
thread's first mention would permanently auto-trigger the bot on every
subsequent message — which is exactly what strict_mention is designed
to prevent. Closes the agent-to-agent ack loop hole hhhonzik identified
in #14117.
Co-authored-by: hhhonzik <me@janstepanovsky.cz>
Adds a strict_mention config option that, when enabled, requires an
explicit @-mention on every message in channel threads. Disables the
'once mentioned, forever in the thread' and session-presence auto-triggers.
- New _slack_strict_mention() helper (config.extra + SLACK_STRICT_MENTION env)
- Bridged top-level slack.strict_mention yaml to SLACK_STRICT_MENTION env,
matching require_mention/allow_bots bridging
- Unit tests for the helper + config bridge
Top-level channel messages arrive at _resolve_thread_ts with
metadata.thread_id set to the message's own ts, because the inbound
handler in _handle_message_event uses 'event.ts' as a session-keying
fallback when event.thread_ts is absent. That made metadata alone
insufficient to distinguish a real thread reply from a top-level
message, so reply_in_thread=false only took effect in DMs.
Use reply_to (== incoming message_id == ts for top-level messages) as
the tiebreaker: when metadata.thread_id == reply_to the 'thread' is the
synthetic session-keying fallback, not a real parent, so we reply
directly in the channel. Real thread replies (reply_to != thread_id)
still resolve to the parent thread and preserve conversation context.
Closes#9268.
Every command in COMMAND_REGISTRY (/btw, /stop, /model, /help, /new,
/bg, /reset, ...) is now a first-class Slack slash command instead of
a /hermes <subcommand>. Users get the same autocomplete-driven slash
picker experience Slack users expect and that Discord and Telegram
already provide.
Previously Slack registered ONE native slash (/hermes) and split on
the first word, so typing /btw in Slack's composer got 'couldn't find
an app for /btw' because the workspace manifest never declared it.
Changes
- hermes_cli/commands.py: slack_native_slashes() + slack_app_manifest()
generate a Slack manifest from the registry (canonical names +
aliases + plugin commands), clamped to Slack's 50-slash cap with
/hermes reserved as the catch-all.
- gateway/platforms/slack.py: single regex matcher dispatches every
registered slash to _handle_slash_command, which dispatches on
command['command']. Legacy /hermes <subcommand> keeps working for
backward compat with older workspace manifests.
- hermes_cli/slack_cli.py + hermes_cli/main.py: new 'hermes slack
manifest' command prints/writes a full manifest (display info,
OAuth scopes, event subs, socket mode, slash commands) ready to
paste into 'Create from manifest' or Features → App Manifest.
- hermes_cli/setup.py: _setup_slack() now writes the manifest up-front
and points users at the 'From an app manifest' flow; also offers
to refresh the manifest on reconfigure for picking up new commands.
- Tests: 14 new tests covering native-slash dispatch (/btw, /stop,
/model), legacy /hermes <sub> compat, manifest structure, and
telegram<->slack parity (every Telegram command must also register
as a Slack slash). Existing /hermes-registration test updated to
assert the new regex matches /hermes, /btw, /stop, /model, /help.
- Docs: slack.md gains a 'Slash Commands' section + Option A manifest
flow in Step 1; cli-commands.md documents 'hermes slack manifest'.
Users pick up the new slashes by running 'hermes slack manifest --write'
and pasting into Features → App Manifest → Edit in their Slack app
config, then Save (Slack prompts for reinstall if scopes changed).
Adds _reactions_enabled() gating to match Discord (DISCORD_REACTIONS) and
Telegram (TELEGRAM_REACTIONS) pattern. Defaults to true to preserve existing
behavior. Gates at three levels:
- _handle_slack_message: skips _reacting_message_ids registration
- on_processing_start: early return
- on_processing_complete: early return
Also adds config.yaml bridge (slack.reactions) and two new tests.
Slack reactions were placed around handle_message(), which returns
immediately after spawning a background task. This caused the 👀
→ ✅ swap to happen before any real work began.
Fix: implement on_processing_start / on_processing_complete callbacks
(matching Discord/Telegram) so reactions bracket actual _message_handler
work driven by the base class.
Also fixes missing stop_typing() for Slack's assistant thread status
indicator, which left 'is thinking...' stuck in the UI after processing
completed.
- Add _reacting_message_ids set for DM/@mention-only gating
- Add _active_status_threads dict for stop_typing lookup
- Update test_reactions_in_message_flow for new callback pattern
- Add test_reactions_failure_outcome and test_reactions_skipped_for_non_dm_non_mention
Sweep ~74 redundant local imports across 21 files where the same module
was already imported at the top level. Also includes type fixes and lint
cleanups on the same branch.
stream_consumer._send_or_edit unconditionally passes finalize= to
adapter.edit_message(), but only DingTalk's override accepted the
kwarg. Streaming on Telegram/Discord/Slack/Matrix/Mattermost/Feishu/
WhatsApp raised TypeError the first time a segment break or final
edit fired.
The REQUIRES_EDIT_FINALIZE capability flag only gates the redundant
final edit (and the identical-text short-circuit), not the kwarg
itself — so adapters that opt out of finalize still receive the
keyword argument and must accept it.
Add *, finalize: bool = False to the 7 non-DingTalk signatures; the
body ignores the arg since those platforms treat edits as stateless
(consistent with the base class contract in base.py).
Add a parametrized signature check over every concrete adapter class
so a future override cannot silently drop the kwarg — existing tests
use MagicMock which swallows any kwarg and cannot catch this.
Fixes#12579
Each top-level Slack DM now gets its own Hermes session, matching the
per-thread behavior channels already have. Previously all top-level DM
messages shared one continuous session because thread_ts was None,
causing context to accumulate across unrelated conversations.
The behavior is controlled by platforms.slack.extra.dm_top_level_threads_as_sessions
in config.yaml (default: true). Set to false to restore legacy behavior.
Based on PR #10789 by helix4u. Changes from original:
- Default flipped to true (was opt-in, now opt-out)
- Removed env var fallback (config.yaml only per project policy)
- Tests updated to cover both default and opt-out paths
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.).
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
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
- 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
except our own, to prevent echo loops).
Configurable via:
slack:
allow_bots: mentions
Or env var: SLACK_ALLOW_BOTS=mentions
Self-message guard always active regardless of mode.
Based on PR #3200 by Mibayy, adapted to current main with config.yaml
bridging support.
Fixes blockquote > escaping, edit_message raw markdown, ***bold italic***
handling, HTML entity double-escaping (&amp;), Wikipedia URL parens
truncation, and step numbering format. Also adds format_message to the
tool-layer _send_to_platform for consistent formatting across all
delivery paths.
Changes:
- Protect Slack entities (<@user>, <https://...|label>, <!here>) from
escaping passes
- Protect blockquote > markers before HTML entity escaping
- Unescape-before-escape for idempotent HTML entity handling
- ***bold italic*** → *_text_* conversion (before **bold** pass)
- URL regex upgraded to handle balanced parentheses
- mrkdwn:True flag on chat_postMessage payloads
- format_message applied in edit_message and send_message_tool
- 52 new tests (format, edit, streaming, splitting, tool chunking)
- Use reversed(dict) idiom for placeholder restoration
Based on PR #3715 by dashed, cherry-picked onto current main.
Port the mention gating pattern from Telegram, Discord, WhatsApp, and
Matrix adapters to the Slack platform adapter.
- Add _slack_require_mention() with explicit-false parsing and env var
fallback (SLACK_REQUIRE_MENTION)
- Add _slack_free_response_channels() with env var fallback
(SLACK_FREE_RESPONSE_CHANNELS)
- 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:
slack:
require_mention: false
free_response_channels:
- "C0AQWDLHY9M"
Default behavior unchanged: channels require @mention (backward compatible).
Based on PR #5885 by dorukardahan, cherry-picked and adapted to current main.
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 the bot sends a message in a thread, track its ts in _bot_message_ts.
When the bot is @mentioned in a thread, register it in _mentioned_threads.
Both sets enable auto-responding to future messages in those threads
without requiring repeated @mentions — making the bot behave like a
team member that stays engaged once a conversation starts.
Channel message gating now checks 4 signals (in order):
1. @mention in this message
2. Reply in a thread the bot started/participated in (_bot_message_ts)
3. Message in a thread where the bot was previously @mentioned (_mentioned_threads)
4. Existing session for this thread (_has_active_session_for_thread — survives restarts)
Thread context fetching now triggers on ANY first-entry path (not just
@mention), so the agent gets context whether it's entering via a mention,
a bot-thread reply, or a mentioned-thread auto-trigger.
Both tracking sets are bounded (5000 cap with prune-oldest-half) to prevent
unbounded memory growth in long-running deployments.
Salvaged from PR #5754 by @hhhonzik. Preserves our existing approval buttons,
thread context fetching, and session key fix. Does NOT include the
edit_message format_message() removal (that was a regression in the original PR).
Tests: 4 new tests for bot-ts tracking and mentioned-thread bounds.
Slack:
- Add Block Kit interactive buttons for command approval (Allow Once,
Allow Session, Always Allow, Deny) via send_exec_approval()
- Register @app.action handlers for each approval button
- Add _fetch_thread_context() — fetches thread history via
conversations.replies when bot is first @mentioned mid-thread
- Fix _has_active_session_for_thread() to use build_session_key()
instead of manual key construction (fixes session key mismatch bug
where thread_sessions_per_user flag was ignored, ref PR #5833)
Telegram:
- Add InlineKeyboard approval buttons via send_exec_approval()
- Add ea:* callback handling in _handle_callback_query()
- Uses monotonic counter + _approval_state dict to map button clicks
back to session keys (avoids 64-byte callback_data limit)
Both platforms now auto-detected by the gateway runner's
_approval_notify_sync() — any adapter with send_exec_approval() on
its class gets button-based approval instead of text fallback.
Inspired by community PRs #3898 (LevSky22), #2953 (ygd58), #5833
(heathley). Implemented fresh on current main.
Tests: 24 new tests covering button rendering, action handling,
thread context fetching, session key fix, double-click prevention.
Comprehensive cleanup across 80 files based on automated (ruff, pyflakes, vulture)
and manual analysis of the entire codebase.
Changes by category:
Unused imports removed (~95 across 55 files):
- Removed genuinely unused imports from all major subsystems
- agent/, hermes_cli/, tools/, gateway/, plugins/, cron/
- Includes imports in try/except blocks that were truly unused
(vs availability checks which were left alone)
Unused variables removed (~25):
- Removed dead variables: connected, inner, channels, last_exc,
source, new_server_names, verify, pconfig, default_terminal,
result, pending_handled, temperature, loop
- Dropped unused argparse subparser assignments in hermes_cli/main.py
(12 instances of add_parser() where result was never used)
Dead code removed:
- run_agent.py: Removed dead ternary (None if False else None) and
surrounding unreachable branch in identity fallback
- run_agent.py: Removed write-only attribute _last_reported_tool
- hermes_cli/providers.py: Removed dead @property decorator on
module-level function (decorator has no effect outside a class)
- gateway/run.py: Removed unused MCP config load before reconnect
- gateway/platforms/slack.py: Removed dead SessionSource construction
Undefined name bugs fixed (would cause NameError at runtime):
- batch_runner.py: Added missing logger = logging.getLogger(__name__)
- tools/environments/daytona.py: Added missing Dict and Path imports
Unnecessary global statements removed (14):
- tools/terminal_tool.py: 5 functions declared global for dicts
they only mutated via .pop()/[key]=value (no rebinding)
- tools/browser_tool.py: cleanup thread loop only reads flag
- tools/rl_training_tool.py: 4 functions only do dict mutations
- tools/mcp_oauth.py: only reads the global
- hermes_time.py: only reads cached values
Inefficient patterns fixed:
- startswith/endswith tuple form: 15 instances of
x.startswith('a') or x.startswith('b') consolidated to
x.startswith(('a', 'b'))
- len(x)==0 / len(x)>0: 13 instances replaced with pythonic
truthiness checks (not x / bool(x))
- in dict.keys(): 5 instances simplified to in dict
- Redefined unused name: removed duplicate _strip_mdv2 import in
send_message_tool.py
Other fixes:
- hermes_cli/doctor.py: Replaced undefined logger.debug() with pass
- hermes_cli/config.py: Consolidated chained .endswith() calls
Test results: 3934 passed, 17 failed (all pre-existing on main),
19 skipped. Zero regressions.
When a user replies in a Slack thread where the bot has an active
conversation session, the bot now processes the message even without
an explicit @mention. This improves UX for ongoing threaded
discussions.
Changes:
- Added set_session_store() to BasePlatformAdapter for adapters to
check active sessions
- Modified SlackAdapter to detect thread replies and check if a
session exists for that thread before requiring @mentions
- Updated GatewayRunner to inject the session store into adapters
- Added comprehensive tests for the new behavior
Fixes: Thread replies without @jarvis are now processed if there is
an active session, matching user expectations for conversation flow
The edit_message method was sending raw content directly to Slack's
chat_update API without converting standard markdown to Slack's mrkdwn
format. This caused broken formatting and malformed URLs (e.g., trailing
** from bold syntax became part of clickable links → 404 errors).
The send() method already calls format_message() to handle this conversion,
but edit_message() was bypassing it. This change ensures edited messages
receive the same markdown → mrkdwn transformation as new messages.
Closes: PR #5558 formatting issue where links had trailing markdown syntax.
* fix(gateway): add message deduplication to Discord and Slack adapters (#4777)
Discord RESUME replays events after reconnects (~7/day observed),
and Slack Socket Mode can redeliver events if the ack was lost.
Neither adapter tracked which messages were already processed,
causing duplicate bot responses.
Add _seen_messages dedup cache (message ID → timestamp) with 5-min
TTL and 2000-entry cap to both adapters, matching the pattern already
used by Mattermost, Matrix, WeCom, Feishu, DingTalk, and Email.
The check goes at the very top of the message handler, before any
other logic, so replayed events are silently dropped.

* fix: prevent duplicate messages on partial stream delivery
When streaming fails after tokens are already delivered to the platform,
_interruptible_streaming_api_call re-raised the error into the outer
retry loop, which would make a new API call — creating a duplicate
message.
Now checks deltas_were_sent before re-raising: if partial content was
already streamed, returns a stub response instead. The outer loop treats
the turn as complete (no retry, no fallback, no duplicate).
Inspired by PR #4871 (@trevorgordon981) which identified the bug.
This implementation avoids monkey-patching exception objects and keeps
the fix within the streaming call boundary.

By default, Hermes always threads replies to channel messages. Teams
that prefer direct channel replies had no way to opt out without
patching the source.
Add a reply_in_thread option (default: true) to the Slack platform
extra config:
platforms:
slack:
extra:
reply_in_thread: false
When false, _resolve_thread_ts() returns None for top-level channel
messages, so replies go directly to the channel. Messages already
inside an existing thread are still replied in-thread to preserve
conversation context. Default is true for full backward compatibility.
Salvaged from PR #2033 by yoannes. Adds multi-workspace Slack support
so a single Hermes instance can serve multiple Slack workspaces after
OAuth installs.

- Support comma-separated bot tokens in SLACK_BOT_TOKEN env var
- Load additional OAuth-persisted tokens from HERMES_HOME/slack_tokens.json
- Route all Slack API calls through workspace-aware _get_client(chat_id)
instead of always using the primary app client
- Track channel → workspace mapping from incoming events
- Per-workspace bot_user_id for correct mention detection
- Workspace-aware file downloads (correct auth token per workspace)
Backward compatible: single-token setups work identically.
Token file format (slack_tokens.json):
{"T12345": {"token": "xoxb-...", "team_name": "My Workspace"}}
Fixed from original PR:
- Uses get_hermes_home() instead of hardcoded ~/.hermes/ path
Co-authored-by: yoannes <yoannes@users.noreply.github.com>
Community review (devoruncommented) correctly identified that the Slack
adapter re-read SLACK_APP_TOKEN from os.getenv() during disconnect,
which could differ from the value used during connect if the environment
changed. Discord had the same pattern with self.config.token (less risky
but still not bulletproof).
Both now follow the Telegram pattern: store the token identity on self
at acquire time, use the stored value for release, clear after release.
Also fixes docs: alias naming was hermes-<name> in docs but actual
implementation creates <name> directly (e.g. ~/.local/bin/coder not
~/.local/bin/hermes-coder).
* fix(gateway): add media download retry to Mattermost, Slack, and base cache
Media downloads on Mattermost and Slack fail permanently on transient
errors (timeouts, 429 rate limits, 5xx server errors). Telegram and
WhatsApp already have retry logic, but these platforms had single-attempt
downloads with hardcoded 30s timeouts.
Changes:
- base.py cache_image_from_url: add retry with exponential backoff
(covers Signal and any platform using the shared cache helper)
- mattermost.py _send_media_url: retry on 429/5xx/timeout (3 attempts)
- slack.py _download_slack_file: retry on timeout/5xx (3 attempts)
- slack.py _download_slack_file_bytes: same retry pattern
* test: add tests for media download retry

Python's asyncio event loop holds only weak references to tasks.
Without a strong reference, the garbage collector can destroy a task
while it's awaiting I/O — silently dropping messages. Python 3.12+
made this more aggressive.
Audit of all gateway platform adapters found 6 untracked create_task
calls across 6 files:
Per-message tasks (tracked via _background_tasks set from base class):
- gateway/platforms/webhook.py: handle_message task
- gateway/platforms/sms.py: handle_message task
- gateway/platforms/signal.py: SSE response aclose task
Long-running infrastructure tasks (stored in named instance vars):
- gateway/platforms/slack.py: Socket Mode handler (_socket_mode_task)
- gateway/platforms/discord.py: bot client (_bot_task)
- gateway/platforms/whatsapp.py: message poll loop (_poll_task, 2 sites)
All other adapters (telegram, mattermost, matrix, email, homeassistant,
dingtalk) already tracked their tasks correctly.
Salvaged from PR #3160 by memosr — expanded from 1 file to 6.
* refactor: centralize slash command registry
Replace 7+ scattered command definition sites with a single
CommandDef registry in hermes_cli/commands.py. All downstream
consumers now derive from this registry:
- CLI process_command() resolves aliases via resolve_command()
- Gateway _known_commands uses GATEWAY_KNOWN_COMMANDS frozenset
- Gateway help text generated by gateway_help_lines()
- Telegram BotCommands generated by telegram_bot_commands()
- Slack subcommand map generated by slack_subcommand_map()
Adding a command or alias is now a one-line change to
COMMAND_REGISTRY instead of touching 6+ files.
Bugfixes included:
- Telegram now registers /rollback, /background (were missing)
- Slack now has /voice, /update, /reload-mcp (were missing)
- Gateway duplicate 'reasoning' dispatch (dead code) removed
- Gateway help text can no longer drift from CLI help
Backwards-compatible: COMMANDS and COMMANDS_BY_CATEGORY dicts are
rebuilt from the registry, so existing imports work unchanged.
* docs: update developer docs for centralized command registry
Update AGENTS.md with full 'Slash Command Registry' and 'Adding a
Slash Command' sections covering CommandDef fields, registry helpers,
and the one-line alias workflow.
Also update:
- CONTRIBUTING.md: commands.py description
- website/docs/reference/slash-commands.md: reference central registry
- docs/plans/centralize-command-registry.md: mark COMPLETED
- plans/checkpoint-rollback.md: reference new pattern
- hermes-agent-dev skill: architecture table
* chore: remove stale plan docs
* feat: add optional smart model routing
Add a conservative cheap-vs-strong routing option that can send very short/simple turns to a cheaper model across providers while keeping the primary model for complex work. Wire it through CLI, gateway, and cron, and document the config.yaml workflow.
* fix(gateway): remove recursive ExecStop from systemd units, extend TimeoutStopSec to 60s
* fix(gateway): avoid recursive ExecStop in user systemd unit
* fix: extend ExecStop removal and TimeoutStopSec=60 to system unit
The cherry-picked PR #1448 fix only covered the user systemd unit.
The system unit had the same TimeoutStopSec=15 and could benefit
from the same 60s timeout for clean shutdown. Also adds a regression
test for the system unit.

* feat(skills): add blender-mcp optional skill for 3D modeling
Control a running Blender instance from Hermes via socket connection
to the blender-mcp addon (port 9876). Supports creating 3D objects,
materials, animations, and running arbitrary bpy code.
Placed in optional-skills/ since it requires Blender 4.3+ desktop
with a third-party addon manually started each session.
* feat(acp): support slash commands in ACP adapter (#1532)
Adds /help, /model, /tools, /context, /reset, /compact, /version
to the ACP adapter (VS Code, Zed, JetBrains). Commands are handled
directly in the server without instantiating the TUI — each command
queries agent/session state and returns plain text.
Unrecognized /commands fall through to the LLM as normal messages.
/model uses detect_provider_for_model() for auto-detection when
switching models, matching the CLI and gateway behavior.
Fixes#1402
* fix(logging): improve error logging in session search tool (#1533)
* fix(gateway): restart on retryable startup failures (#1517)
* feat(email): add skip_attachments option via config.yaml
* feat(email): add skip_attachments option via config.yaml
Adds a config.yaml-driven option to skip email attachments in the
gateway email adapter. Useful for malware protection and bandwidth
savings.
Configure in config.yaml:
platforms:
email:
skip_attachments: true
Based on PR #1521 by @an420eth, changed from env var to config.yaml
(via PlatformConfig.extra) to match the project's config-first pattern.
* docs: document skip_attachments option for email adapter
* fix(telegram): retry on transient TLS failures during connect and send
Add exponential-backoff retry (3 attempts) around initialize() to
handle transient TLS resets during gateway startup. Also catches
TimedOut and OSError in addition to NetworkError.
Add exponential-backoff retry (3 attempts) around send_message() for
NetworkError during message delivery, wrapping the existing Markdown
fallback logic.
Both imports are guarded with try/except ImportError for test
environments where telegram is mocked.
Based on PR #1527 by cmd8. Closes#1526.
* feat: permissive block_anchor thresholds and unicode normalization (#1539)
Salvaged from PR #1528 by an420eth. Closes#517.
Improves _strategy_block_anchor in fuzzy_match.py:
- Add unicode normalization (smart quotes, em/en-dashes, ellipsis,
non-breaking spaces → ASCII) so LLM-produced unicode artifacts
don't break anchor line matching
- Lower thresholds: 0.10 for unique matches (was 0.70), 0.30 for
multiple candidates — if first/last lines match exactly, the
block is almost certainly correct
- Use original (non-normalized) content for offset calculation to
preserve correct character positions
Tested: 3 new scenarios fixed (em-dash anchors, non-breaking space
anchors, very-low-similarity unique matches), zero regressions on
all 9 existing fuzzy match tests.

* feat(cli): add file path autocomplete in the input prompt (#1545)
When typing a path-like token (./ ../ ~/ / or containing /),
the CLI now shows filesystem completions in the dropdown menu.
Directories show a trailing slash and 'dir' label; files show
their size. Completions are case-insensitive and capped at 30
entries.
Triggered by tokens like:
edit ./src/ma → shows ./src/main.py, ./src/manifest.json, ...
check ~/doc → shows ~/docs/, ~/documents/, ...
read /etc/hos → shows /etc/hosts, /etc/hostname, ...
open tools/reg → shows tools/registry.py
Slash command autocomplete (/help, /model, etc.) is unaffected —
it still triggers when the input starts with /.
Inspired by OpenCode PR #145 (file path completion menu).
Implementation:
- hermes_cli/commands.py: _extract_path_word() detects path-like
tokens, _path_completions() yields filesystem Completions with
size labels, get_completions() routes to paths vs slash commands
- tests/hermes_cli/test_path_completion.py: 26 tests covering
path extraction, prefix filtering, directory markers, home
expansion, case-insensitivity, integration with slash commands
* feat(privacy): redact PII from LLM context when privacy.redact_pii is enabled
Add privacy.redact_pii config option (boolean, default false). When
enabled, the gateway redacts personally identifiable information from
the system prompt before sending it to the LLM provider:
- Phone numbers (user IDs on WhatsApp/Signal) → hashed to user_<sha256>
- User IDs → hashed to user_<sha256>
- Chat IDs → numeric portion hashed, platform prefix preserved
- Home channel IDs → hashed
- Names/usernames → NOT affected (user-chosen, publicly visible)
Hashes are deterministic (same user → same hash) so the model can
still distinguish users in group chats. Routing and delivery use
the original values internally — redaction only affects LLM context.
Inspired by OpenClaw PR #47959.
* fix(privacy): skip PII redaction on Discord/Slack (mentions need real IDs)
Discord uses <@user_id> for mentions and Slack uses <@U12345> — the LLM
needs the real ID to tag users. Redaction now only applies to WhatsApp,
Signal, and Telegram where IDs are pure routing metadata.
Add 4 platform-specific tests covering Discord, WhatsApp, Signal, Slack.
* feat: smart approvals + /stop command (inspired by OpenAI Codex)
* feat: smart approvals — LLM-based risk assessment for dangerous commands
Adds a 'smart' approval mode that uses the auxiliary LLM to assess
whether a flagged command is genuinely dangerous or a false positive,
auto-approving low-risk commands without prompting the user.
Inspired by OpenAI Codex's Smart Approvals guardian subagent
(openai/codex#13860).
Config (config.yaml):
approvals:
mode: manual # manual (default), smart, off
Modes:
- manual — current behavior, always prompt the user
- smart — aux LLM evaluates risk: APPROVE (auto-allow), DENY (block),
or ESCALATE (fall through to manual prompt)
- off — skip all approval prompts (equivalent to --yolo)
When smart mode auto-approves, the pattern gets session-level approval
so subsequent uses of the same pattern don't trigger another LLM call.
When it denies, the command is blocked without user prompt. When
uncertain, it escalates to the normal manual approval flow.
The LLM prompt is carefully scoped: it sees only the command text and
the flagged reason, assesses actual risk vs false positive, and returns
a single-word verdict.
* feat: make smart approval model configurable via config.yaml
Adds auxiliary.approval section to config.yaml with the same
provider/model/base_url/api_key pattern as other aux tasks (vision,
web_extract, compression, etc.).
Config:
auxiliary:
approval:
provider: auto
model: '' # fast/cheap model recommended
base_url: ''
api_key: ''
Bridged to env vars in both CLI and gateway paths so the aux client
picks them up automatically.
* feat: add /stop command to kill all background processes
Adds a /stop slash command that kills all running background processes
at once. Currently users have to process(list) then process(kill) for
each one individually.
Inspired by OpenAI Codex's separation of interrupt (Ctrl+C stops current
turn) from /stop (cleans up background processes). See openai/codex#14602.
Ctrl+C continues to only interrupt the active agent turn — background
dev servers, watchers, etc. are preserved. /stop is the explicit way
to clean them all up.
* feat: first-class plugin architecture + hide status bar cost by default (#1544)
The persistent status bar now shows context %, token counts, and
duration but NOT $ cost by default. Cost display is opt-in via:
display:
show_cost: true
in config.yaml, or: hermes config set display.show_cost true
The /usage command still shows full cost breakdown since the user
explicitly asked for it — this only affects the always-visible bar.
Status bar without cost:
⚕ claude-sonnet-4 │ 12K/200K │ 6% │ 15m
Status bar with show_cost: true:
⚕ claude-sonnet-4 │ 12K/200K │ 6% │ $0.06 │ 15m
* feat: improve memory prioritization + aggressive skill updates (inspired by OpenAI Codex)
* feat: improve memory prioritization — user preferences over procedural knowledge
Inspired by OpenAI Codex's memory prompt improvements (openai/codex#14493)
which focus memory writes on user preferences and recurring patterns
rather than procedural task details.
Key insight: 'Optimize for reducing future user steering — the most
valuable memory prevents the user from having to repeat themselves.'
Changes:
- MEMORY_GUIDANCE (prompt_builder.py): added prioritization hierarchy
and the core principle about reducing user steering
- MEMORY_SCHEMA (memory_tool.py): reordered WHEN TO SAVE list to put
corrections first, added explicit PRIORITY guidance
- Memory nudge (run_agent.py): now asks specifically about preferences,
corrections, and workflow patterns instead of generic 'anything'
- Memory flush (run_agent.py): now instructs to prioritize user
preferences and corrections over task-specific details
* feat: more aggressive skill creation and update prompting
Press harder on skill updates — the agent should proactively patch
skills when it encounters issues during use, not wait to be asked.
Changes:
- SKILLS_GUIDANCE: 'consider saving' → 'save'; added explicit instruction
to patch skills immediately when found outdated/wrong
- Skills header: added instruction to update loaded skills before finishing
if they had missing steps or wrong commands
- Skill nudge: more assertive ('save the approach' not 'consider saving'),
now also prompts for updating existing skills used in the task
- Skill nudge interval: lowered default from 15 to 10 iterations
- skill_manage schema: added 'patch it immediately' to update triggers
* feat: first-class plugin architecture (#1555)
Plugin system for extending Hermes with custom tools, hooks, and
integrations — no source code changes required.
Core system (hermes_cli/plugins.py):
- Plugin discovery from ~/.hermes/plugins/, .hermes/plugins/, and
pip entry_points (hermes_agent.plugins group)
- PluginContext with register_tool() and register_hook()
- 6 lifecycle hooks: pre/post tool_call, pre/post llm_call,
on_session_start/end
- Namespace package handling for relative imports in plugins
- Graceful error isolation — broken plugins never crash the agent
Integration (model_tools.py):
- Plugin discovery runs after built-in + MCP tools
- Plugin tools bypass toolset filter via get_plugin_tool_names()
- Pre/post tool call hooks fire in handle_function_call()
CLI:
- /plugins command shows loaded plugins, tool counts, status
- Added to COMMANDS dict for autocomplete
Docs:
- Getting started guide (build-a-hermes-plugin.md) — full tutorial
building a calculator plugin step by step
- Reference page (features/plugins.md) — quick overview + tables
- Covers: file structure, schemas, handlers, hooks, data files,
bundled skills, env var gating, pip distribution, common mistakes
Tests: 16 tests covering discovery, loading, hooks, tool visibility.
* feat: add /bg as alias for /background slash command
Adds /bg alias across CLI, gateway, and Slack platform adapter.
Updates help text, autocomplete, known_commands set, and dispatch
logic. Includes tests for the new alias.
* docs: add plan for centralized slash command registry
Scopes a refactor to replace 7+ scattered command definition sites
with a single CommandDef registry in hermes_cli/commands.py. Includes
derived helper functions for gateway help text, Telegram BotCommands,
Slack subcommand maps, and alias resolution.
Documents current drift (Telegram missing /rollback + /background,
Slack missing /voice + /update, gateway dead code) that the refactor
fixes for free.

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).
