Add a per-platform `cron_continuable_surface` extra key
(`thread` default | `in_channel`) so a continuable cron job can deliver
FLAT into a Slack channel — no dedicated thread — and still be
replied-to. In `in_channel` mode the scheduler skips the thread-open
branch (leaves `thread_id=None`); the shipped origin-mirror then seeds
the `(slack, chat_id, None)` shared-channel session — the same bucket
`reply_in_thread: false` routes inbound channel replies to — so a plain
channel reply continues the job in context.
Design: specs/cron-inchannel-continuable (D1–D7, F5). Model B
(shared-channel session), NOT anchoring to the delivery `ts` — on Slack
replying to a specific message IS threading, so a `ts` anchor would only
relocate the thread, never deliver true threadless continuable.
- gateway/platforms/base.py: `supports_inchannel_continuable` capability
flag (default False → unsupported platforms fail SAFE to `thread`).
- plugins/platforms/slack/adapter.py: flag=True; `_cron_continuable_surface()`
resolver (coerces to the two-value enum); `_warn_if_inchannel_without_flat_reply`
connect-time warning (D5: warn, not hard-require — the misconfig fails safe).
- gateway/config.py: shared-key bridge line (top-level OR nested config).
- cron/scheduler.py: read the key generically from platform config, gate
the `in_channel` branch on the adapter capability flag, skip thread-open.
No new seed function (reuses the existing mirror — G6).
Pairing (docs): `in_channel` + `reply_in_thread: false` +
`require_mention: false` (or a free-response channel). Missing
`reply_in_thread: false` fails safe to a threaded continuation.
Gateway-side config flag — `/restart` to apply; NO Slack app reinstall.
Tests (from inside the worktree, PYTHONPATH=$PWD):
- +6 cron scheduler tests (in_channel skips thread-open; seeds flat
channel session with thread_id=None; thread-mode regression;
fail-safe on unsupported platform; value coercion). Prove-fail:
removing the `and not in_channel_surface` guard turns the two
load-bearing tests RED; restore → GREEN.
- +10 slack resolver/capability/warning tests; +2 config-bridge tests.
- tests/manual/cron_inchannel_e2e.py: offline E2E driving BOTH real
legs (delivery seed + inbound reply keying) → both converge on
(slack, C, None).
- No regressions: test_slack.py 216 passed alone; broader sweep green
(4 pre-existing cross-file-ordering failures reproduce identically on
pristine origin/main).
Docs: cron.md + slack.md + zh-Hans mirrors of both.
Follow-up to the #55780 dead-target not_found blast-radius fix (merged in
#56225). classify_send_error and is_chat_level_not_found each built their own
lowercased error blob, but divergently: classify_send_error appended the
exception CLASS NAME while is_chat_level_not_found did not. A caller passing
exc= to both could get inconsistent answers on the same failure.
- Extract _error_blob(exc, error_text) as the single source of truth both
classifiers use (str(exc) when non-empty + class name; no stray leading
space).
- Align is_chat_level_not_found's signature to (exc, error_text), matching
classify_send_error, removing the swapped-positional footgun; update the
sole caller and the three tests to keyword form.
- Add a regression guard asserting _error_blob keeps the class name.
Surfaced by the hermes-pr-review Phase 2c structured review of #56225.
#55115 added the dead-target registry so confirmed-dead delivery targets are
short-circuited. Its documented scope (gateway/dead_targets.py) is deliberately
narrow: only *whole-chat* deaths -- the `forbidden` and chat-level `not_found`
(`chat not found`) kinds -- should be recorded; "Thread/topic-level not_found is
NOT recorded here ... a deleted topic does not mean the parent chat is dead."
But the implementation doesn't honor that scope. classify_send_error collapses
chat-level "chat not found" AND thread/message-level not_found ("thread not
found", "topic_deleted", "message_id_invalid", "message to edit/reply not
found") into one "not_found" kind, _DEAD_ERROR_KINDS contains "not_found"
wholesale, and deliver()'s except marks the PARENT chat_id dead. So a single
deleted Telegram topic or edited-away message permanently marks the entire chat
(and every future scheduled / cron / agent delivery to it) dead -- silently. The
adapter self-heal the docstring relies on only covers the non-private-group
thread retry; named-DM-topic and message-level failures propagate to deliver()'s
except and wrongly kill the whole chat.
Add is_chat_level_not_found() (factoring the not_found substrings into chat-level
vs sub-chat-level constants) and gate the delivery dead-path: a "not_found" only
marks the target dead when it is chat-level. classify_send_error's public
contract is unchanged (still returns "not_found" for every shape); only the
mark_dead decision is refined, restoring the registry's documented scope.
Cross-platform: telegram/slack/discord delivery all flow through
classify_send_error -> mark_dead. Adds regression tests through the real
deliver() path plus helper/classifier units.
When two features register a post-delivery callback for the same session
(e.g. background-review release + /goal continuation), the second
registration is composed with the first via a `_chained` wrapper. That
wrapper was `def _chained()` — a sync function calling each callback
via `_prev()` / `_new()` and discarding the return value.
For sync callbacks that's fine. For async callbacks (such as the
`_deliver()` coroutine the /goal feature registers to inject the
continuation prompt) the returned coroutine was silently dropped:
RuntimeWarning: coroutine '_deliver' was never awaited.
Outer invoker in `_handle_message` already checks
`inspect.isawaitable(_post_result)` and awaits — but only sees the
wrapper's return value, which was `None`.
Fix: make `_chained` async, iterate over chained callbacks, await any
that return an awaitable. Outer invoker already handles awaitable
wrappers, so no other change is needed.
Tested:
* Added two regression tests in test_post_delivery_callback_chaining.py
covering an async callback chained behind sync (and vice versa).
* Updated existing chaining tests + test_run_cleanup_progress.py to
await the popped callback when it's awaitable.
* 62 tests pass across the touched suites.
Live-validated on Discord: /goal continuations now arrive after the
first turn's response is delivered (previously silent).

mcp-tokens/ holds live MCP OAuth access tokens (<server>.json) and
dynamically-registered OAuth client credentials (<server>.client.json),
layout per tools/mcp_oauth.py. This is the same credential class as
auth.json/credentials/, which _media_delivery_denied_paths() already
blocks. The write side already denies this dir (file_tools
_check_sensitive_path), but the media-delivery (read/exfil) side did
not, leaving an unpaired half-door.
Without it, a prompt-injection MEDIA: tag emitting
~/.hermes/mcp-tokens/<server>.json would, in default (non-strict)
mode, pass the denylist and exfiltrate a live OAuth bearer token to
the same untrusted channel. Sibling follow-up to commit 4ec0adebe
(config.yaml media-delivery denylist).
mcp-tokens is a directory and _path_under_denied_prefix already does
containment matching, so the whole subtree (.json/.client.json/
.meta.json) is denied, mirroring credentials/.
Inside httpx AsyncClient response event hooks, response.next_request is
often None even for a genuine redirect, so guards keyed on
`if response.is_redirect and response.next_request` silently never fire.
A public URL that 302s to http://169.254.169.254/ was followed anyway,
defeating the pre-flight is_safe_url() check.
Resolve the redirect target from the Location header (via urljoin, so
relative Locations work too), falling back to next_request only when no
Location is present. Extracted as tools.url_safety.redirect_target_from_response
and wired into every SSRF redirect guard:
- gateway/platforms/base.py (shared image + audio download for all platforms)
- tools/vision_tools.py (two download hooks)
- plugins/platforms/slack/adapter.py
Original fix by @zapabob (PR #35940), which targeted the since-refactored
gateway/platforms/slack.py; reconstructed onto the current shared sites and
widened to the whole bug class.
Mitigates indirect prompt injection (CWE-863) in Slack thread context.
When the bot is mentioned mid-thread for the first time, _fetch_thread_context
pulls the full thread via conversations.replies and prepends every reply to
the LLM prompt. Replies from senders not on the allowlist were rendered
identically to authorised senders, letting a third party in a shared channel
inject instructions the model might act on when answering the next authorised
message.
- BasePlatformAdapter.set_authorization_check / _is_sender_authorized, registered
by GatewayRunner._make_adapter_auth_check() with a closure over the existing
_is_user_authorized chain (platform/global/group allowlists, allow-all flags,
pairing store all stay the single source of truth — no env-var re-parsing).
- Tags non-bot thread messages whose sender fails the auth check with an
[unverified] prefix; strengthens the header with soft guidance only when at
least one unverified message is present, so setups without an allowlist see
no behaviour change.
- Wired into all three adapter-init sites in run.py (start, reconnect watcher,
restart) so the reconnect path is covered too.
Softened wording: adapted from the original [untrusted] tag to [unverified]
and non-accusatory header framing — the label reflects allowlist status, not
a judgment about the person. Adapter relocated to plugins/platforms/slack/
since the PR was authored.
Salvaged from #17059.
In single-process multi-profile runtimes (desktop tui_gateway), profile
scoping is a context-local ContextVar override, not a process env var. Three
subsystems froze their HERMES_HOME-derived paths at import time (or read
os.environ directly), pinning every later profile to whichever profile first
imported the module — a cross-profile data leak.
- tools/skills_hub.py: SKILLS_DIR/HUB_DIR/LOCK_FILE/etc. were module constants
frozen at import. Replace with per-call resolver functions; add a PEP 562
module __getattr__ so external 'from tools.skills_hub import SKILLS_DIR'
callers (all function-local) resolve dynamically with no call-site changes.
Convert default-arg bindings (HubLockFile/TapsManager) and the derived
HERMES_INDEX_CACHE_FILE constant too.
- gateway/platforms/base.py: image/audio/video/document cache-dir getters now
re-resolve via get_hermes_dir() per call, falling back to the module
constant when a test has monkeypatched it (preserves the existing test seam).
Media-delivery safe-roots already enumerate all profiles' cache dirs
(#31733), so per-profile resolution does not break delivery.
- gateway/rich_sent_store.py: _store_path() read os.environ['HERMES_HOME']
directly, bypassing the override entirely; route through get_hermes_home().
The extension-less MEDIA delivery guards short-circuited on
"MEDIA: not in text and [[audio_as_voice]] not in text", so a
response carrying only [[as_document]] (an image-only reply requesting
unmodified document delivery) leaked the directive as visible text.
Add [[as_document]] to both guard conditions (_strip_media_tag_directives
and strip_media_directives_for_display) and cover it with a regression
test.
Files like Caddyfile or Makefile have no extension, so MEDIA_TAG_CLEANUP_RE
never matched them and Telegram showed the raw MEDIA: line as text. Extract
and strip validated extension-less tags via a second pass.
In `WHATSAPP_MODE=bot` the bridge currently drops every fromMe inbound
message — they are all assumed to be echoes of our own /send calls.
That makes it impossible for plugins / agents to detect when a human
owner has typed directly into a customer chat from the same WhatsApp
Business account (e.g. via a linked phone or WhatsApp Web).
This adds an opt-in `WHATSAPP_FORWARD_OWNER_MESSAGES` env var. When
true, the bridge classifies fromMe inbound by looking up `key.id` in a
bounded LRU of recently-sent message IDs (the existing 50-entry echo
suppressor, bumped to 512 and extracted to a testable
`outbound_ids.js` helper). Hits in the LRU are still dropped (echoes);
misses are forwarded to the Python adapter with `fromOwner: true`.
The Python adapter lifts that flag onto
`MessageEvent.metadata["whatsapp_from_owner"]`. `metadata` is a new
free-form dict on the event so future per-platform signals don't each
need their own field. Default behaviour is unchanged: with the env
flag unset, bot mode still drops every fromMe message exactly as
before.
Use cases for downstream consumers:
- Implicit handover activation when the owner replies manually
- Sliding TTL on owner activity (keep an active session alive while
the owner is engaged)
- Audit trails of owner interventions
- Analytics on human-vs-bot reply ratios
Heuristic limitation (documented in code): the LRU is in-memory. After
a bridge restart, in-flight delivery receipts of pre-restart sends will
briefly look like owner-typed for a few seconds until the set is
repopulated. Persisting isn't worth the disk churn — downstream
consumers should treat the flag as best-effort.
Tests:
- tests/gateway/test_whatsapp_from_owner.py (new): adapter sets the
metadata flag iff the bridge payload has `fromOwner: true`; absent
otherwise.
- scripts/whatsapp-bridge/outbound_ids.test.mjs (new): LRU bounds,
eviction order, falsy-id handling.
Backwards compatibility: with the env flag unset, every code path is
identical to before. No existing deployment is affected.
The base BasePlatformAdapter implementations of send_voice, send_video,
send_document, and send_image_file forwarded their *_path argument
verbatim into the chat text (e.g. "🎬 Video: /home/.../hermes/cache/...").
Telegram, Discord, and Slack adapters all fall back to those base methods
when their native send raises — so a rejected video on Telegram surfaced
the host filesystem layout to the user instead of a useful message.
Replace the path-echo with a friendly notice, log the path for operator
diagnostics, and keep the user-supplied caption intact. The Slack adapter
had three identical sites that fell through to the same path-echo on its
own native upload failures; fix those too. send_document still surfaces
the caller-provided file_name (or the basename derived from it) since
that is the user-facing filename, not a host path.
Add regression tests asserting the *_path argument never appears in the
fallback content while caption text and explicit file_name still do.
Add a generic per-platform PlatformConfig.typing_indicator flag (default
True) that gates the _keep_typing refresh loop in
_process_message_background. When false, the loop is never spawned, so no
typing/"is thinking…" status is shown on that platform — message delivery
is otherwise unchanged.
Mirrors the gateway_restart_notification contract exactly: dataclass field
+ to_dict/from_dict (with extra-fallback resolution) + shared-key bridge in
load_gateway_config, so 'slack: typing_indicator: false' under platforms
works without a separate block. Generic by design — the same key works for
every platform (Slack 'is thinking…', Telegram/Discord/Signal typing).
Motivated by users who find Slack's assistant 'is thinking…' status noisy
(it also briefly disables the compose box, via the Assistant API).
The topic-mode helpers (_telegram_topic_mode_enabled,
_recover_telegram_topic_thread_id, _record/_sync_telegram_topic_binding,
_is_telegram_topic_lane/_root_lobby, _normalize_source_for_session_key,
_telegram_topic_new_header, _schedule_telegram_topic_title_rename, and the
base.py _apply_topic_recovery hook) each run a synchronous SessionDB read or
write. They reach the event loop through async handlers, so a contended
state.db froze the loop the same way the handoff watcher did.
These helpers already run off-loop in the run_sync thread-pool closure, so
they are proven thread-safe there. Rather than colour them async, loop-side
callers now invoke them via asyncio.to_thread(...); the executor callers are
unchanged. Inside the helpers the SessionDB handle is unwrapped to the sync
door (getattr(db, '_db', db)) since they always run on a worker thread, and
AIAgent construction + query_session_listing are handed the sync SessionDB
directly. base.py wraps its single _apply_topic_recovery call in to_thread.
The guard is now alias-aware (catches db = getattr(self, '_session_db', None);
db.method(...)) and enforces the offload contract: the offloaded sync helpers
may never be called bare on the loop. Sibling test fixtures wrap their injected
SessionDB in AsyncSessionDB to match how the gateway holds it.
* fix(gateway): log error-notification failures instead of silently swallowing
The last-resort exception handler in _process_message_background() that
sends an error notice to the user caught all exceptions with a bare pass,
leaving zero trace when the notification itself failed. Upgrade to
logger.error(..., exc_info=True) so a failed error-notification send is
debuggable post-mortem.
Salvaged from #6499 by @BongSuCHOI (the logging-upgrade portion only).
* docs: add PR infographic for gateway error-notify logging
When a stale lock file survives a gateway crash, `acquire_scoped_lock()`
may return `(False, existing_dict)` even after detecting and deleting
the stale lock (e.g. if unlink fails or a race condition occurs).
Previously, `_acquire_platform_lock()` called
`_set_fatal_error(..., retryable=False)`, which permanently killed the
platform — the reconnect watcher never retries a non-retryable fatal
error.
Change to `retryable=True` so the platform enters the "retrying"
state and the reconnect watcher can attempt acquisition again after the
standard backoff delay.
Fixes#54167
Generated images under a profile gateway's cache (profiles/<name>/cache/
images/...) were silently dropped from Telegram/Discord delivery when
HERMES_HOME is symlinked under a denied prefix (e.g. /opt/data ->
/root/.hermes) and $HOME is not that prefix. The resolved path lands
under /root (a system denylist prefix), the root-home exception only
fires when the denied prefix IS $HOME, and the static safe-roots list
only covers the active HERMES_HOME's top-level cache — not per-profile
cache dirs. Both gates fail, so validate_media_delivery_path returns
None and the gateway logs 'Skipping unsafe MEDIA directive path'.
_media_delivery_allowed_roots() now also enumerates per-profile cache
roots (<root>/profiles/*/cache/{images,audio,videos,documents,
screenshots}) at check time. Allowlist match runs before the denylist,
so the profile artifact delivers regardless of the /root interaction;
profile-dir credentials (auth.json) stay blocked since they aren't
under a cache subdir.
Reopened regression of #34485/#38108, neither of which covered the
profile-scoped symlink case. Fixes#31733.
After a prolonged outage the in-process network-error ladder escalates to
fatal and GatewayRunner._platform_reconnect_watcher rebuilds a fresh adapter
that reconnects through the bootstrap path. That path called
start_polling(drop_pending_updates=True), discarding every update Telegram
queued during the outage — all messages sent while the bot was down were
silently lost. The in-process ladder and 409-conflict handler already passed
drop_pending_updates=False; only bootstrap did not distinguish a cold first
boot from a reconnect.
Thread an is_reconnect signal from the watcher through
_connect_adapter_with_timeout into adapter.connect(). The base
BasePlatformAdapter.connect() gains a keyword-only is_reconnect=False so every
adapter inherits a tolerant signature (no per-platform breakage when the
runner forwards the kwarg). Telegram translates is_reconnect into
drop_pending_updates=not is_reconnect on both the polling and webhook bootstrap
calls. Cold boot still drops the stale queue; a watcher reconnect preserves it.
Fixes#46621.

A hosted instance fronted by the Team Gateway connector dropped EVERY relay
message as "Unauthorized user" and the agent never replied — despite the
message routing correctly through the connector to the instance.
Root cause: gateway authorization (_is_user_authorized) had no notion of
upstream-enforced authz. Platform.RELAY matches no {PLATFORM}_ALLOWED_USERS
allowlist and isn't in the HA/WEBHOOK always-authorized set, so a relay user
with no env allowlist configured hit the default-deny ("No user allowlists
configured. All unauthorized users will be denied."). The message was received,
then silently denied before reaching the agent.
This is incorrect for relay: the connector authenticates the gateway's WS with
a per-instance secret and performs owner-only author-binding resolution BEFORE
delivering. A message only reaches this gateway because the connector resolved
it to THIS instance's bound user (user_instance_binding), keyed on the author id
the connector OBSERVED off the event — never a gateway claim. The authorization
decision is already made by a trusted, authenticated upstream; there is no local
RELAY_ALLOWED_USERS allowlist to consult, and default-denying for its absence is
the bug.
Fix: add a generic BasePlatformAdapter.authorization_is_upstream capability
(default False) that the relay adapter overrides to True, plus a dedicated
trusted branch in _is_user_authorized that honors it. This is delegation to a
trusted upstream, NOT a fail-open: it fires only for an adapter that explicitly
declares the flag; every direct network-exposed adapter leaves it False and the
env-allowlist default-deny (SECURITY.md §2.6) is unchanged. Distinct from
enforces_own_access_policy, which mirrors a LOCAL config-driven allowlist —
this delegates to an authenticated upstream's decision.
Tests: behavior contract that the base defaults False, the relay adapter
declares True, a relay user (group + DM) is authorized with no env allowlist,
and crucially a non-upstream adapter with no allowlist still default-denies
(guards against the fix becoming a blanket fail-open). 6 new tests; relay +
authz + config-policy suites green (134 + 90).
Found via live staging debug of the Discord self-serve onboarding flow.
When Telegram's sendRichMessage returns a FloodWait/RetryAfter error,
_try_send_rich() now extracts the server-provided retry_after value and
propagates it through SendResult.retry_after. The base _send_with_retry()
layer honors this value instead of using its default short exponential
backoff (~2s, ~4s), preventing the retry budget from being exhausted
against a server that demands a 25-37s wait.

Closes#46762
_session_task_is_stale() failed to detect a stale session lock when the owner
task completed and cleaned _session_tasks (del in _process_message_background's
finally) but _active_sessions was NOT released because _release_session_guard
skipped on a guard mismatch (a concurrent reset/new command or drain handoff
swapped _active_sessions[key] to a different guard). With no owner task left to
inspect, _session_task_is_stale reported 'not stale', the orphaned guard was
never healed, and the session deadlocked permanently — later messages received
but never dispatched.
Reorder the finally cleanup to release-then-conditional-delete: release the
guard first, then drop the _session_tasks entry ONLY if the guard was actually
released (session_key no longer in _active_sessions). On a guard mismatch the
done-task entry survives, so the on-entry self-heal (_session_task_is_stale ->
_heal_stale_session_lock) detects the stale lock and clears it on the next
inbound message.
Extracted the cleanup into a callable _cleanup_finished_session_task() helper so
the regression test drives the REAL production code path rather than a copy of
its logic (the original test inlined the fixed logic and passed regardless of
the production order — mutation-verified the rewritten tests now fail on the
buggy del-first order). Added a positive-path test (guard matches -> release +
delete) so both branches are pinned.

The media-delivery denylist in gateway/platforms/base.py enumerated only
.env/auth.json/credentials/config.yaml under HERMES_HOME, so other
credential stores that live at the root fell through and could be
auto-attached to chat replies. The reported case: the Google Workspace
skill's google_token.json refreshes every turn, bumping its mtime to
'now', which kept passing the strict-mode recency window and re-sent the
OAuth token on every reply.
Extend the explicit per-file denylist to mirror the canonical credential
set already enforced by the read/write guards in agent/file_safety.py:
google_token.json, google_oauth_pending.json, auth/google_oauth.json,
.anthropic_oauth.json, webhook_subscriptions.json, cache/bws_cache.json,
auth.lock, and the pairing/ token directory.
Targeted per-file additions (not a blanket ~/.hermes deny, which was
declined in #32090/#34425 because it would block skills/, logs/, and
ad-hoc agent-written deliverables). mcp-tokens/ (#37222) and
state.db/kanban.db (#41071) are left to their sibling targeted PRs.
Reported-by: xxxigm (#50912)
Gateway-level truncation (MAX_PLATFORM_OUTPUT=4000) was pre-empting
adapter-side message splitting. Discord and Telegram both chunk long
content natively in their send() via truncate_message(), but the
delivery router truncated to 3800 chars + footer before the adapter
ever saw the full payload — so long cron output was cut short instead
of being delivered as multiple messages (issue #50126).
Changes:
- HERMES_DELIVERY_MAX_PLATFORM_OUTPUT env var makes the cap configurable
(default 4000, backward compatible). Set to 0 to disable truncation.
- TRUNCATED_VISIBLE (3800) removed — visible portion now derived
dynamically from max_output minus the actual footer length.
- New BasePlatformAdapter.splits_long_messages capability flag (default
False). Adapters that chunk in send() set True; delivery skips
truncation for them but still saves full output to disk as audit.
- Flagged Discord and Telegram (both verified to chunk in send()).
Fixes#50126
Authorization to message the agent is the gate, not the file extension.
Previously the inbound-attachment allowlist (SUPPORTED_DOCUMENT_TYPES) was
opt-OUT on Discord (allow_any_attachment defaulted false) and had no bypass
at all on Telegram/Slack — so an .html (or any non-allowlisted type) was
dropped or hard-rejected before the agent saw it.
Now every authorized upload is cached and surfaced to the agent regardless
of type:
- base.cache_media_bytes(): unknown types cache as octet-stream (or the
caller-supplied MIME) instead of returning None — fixes the chokepoint
that Teams/Telegram-media route through.
- discord/telegram/slack adapters: removed the allowlist reject/skip; any
non-media attachment is typed DOCUMENT and cached. Known types keep their
precise MIME.
- Text inlining now gates on a shared _TEXT_INJECT_EXTENSIONS set (text +
code + config + markup) instead of a blind UTF-8 decode, so binary formats
(PDF/zip/docx) with ASCII headers are never inlined.
- gateway/run.py emits the path-pointing context note for every DOCUMENT,
including non text/application MIME types.
- discord.allow_any_attachment is now a documented no-op kept for config
back-compat.
Validation: 357 gateway tests pass; E2E confirms .html/.bin/custom types
cache, known types stay precise, PDFs are not inlined.
Add a platform-neutral send-failure vocabulary so consumers can branch on a
typed category instead of substring-matching the raw provider message.
- base.py: SEND_ERROR_KINDS + classify_send_error() (too_long / bad_format /
forbidden / not_found / rate_limited / transient / unknown), and an optional
SendResult.error_kind field (defaults None — fully backward compatible).
- telegram.py: populate error_kind on send() failures; message_too_long keeps
its existing error token plus error_kind='too_long'.
Purely additive: no behavioral change to the existing degrade-and-deliver
paths (MarkdownV2->plain-text fallback, overflow split, retry classification
all untouched). 22 new tests + 210 adapter regression tests green.
* fix(api-server): stop silently promising async delivery on stateless HTTP path
terminal(notify_on_complete=True / watch_patterns) and delegate_task(background=True)
silently no-op'd on the API server / WebUI path (#10760): the watcher / detached
child registered, but every API-server route (OpenAI-spec /v1/chat/completions
and /v1/responses, plus the proprietary /v1/runs SSE stream) tears down its
channel when the turn ends, and APIServerAdapter.send() is a no-op stub. A
completion that fires after the response closed had nowhere to go — from the
agent side, indistinguishable from a hang.
There is no spec-compliant surface to wake the agent later on a stateless HTTP
client, so make the no-op honest instead of silent:
- Add a per-adapter capability flag supports_async_delivery (default True;
APIServerAdapter = False), propagated into a HERMES_SESSION_ASYNC_DELIVERY
contextvar via async_delivery_supported(). Toggle on the adapter, not a
hardcoded platform string — a future stateless adapter is correct-by-default.
- terminal: when delivery is unsupported, skip watcher registration, force
notify_on_complete off, and return a notify_unsupported note telling the
agent to process(action='poll').
- delegate_task: when delivery is unsupported, fall back to SYNCHRONOUS
execution (work runs and returns in the same response) with a note, instead
of handing out a handle that never resolves.
CLI (in-process completion_queue) and the real gateway platforms are unchanged.
Fixes#10760
* refactor(api-server): route session binding through a single no-delivery chokepoint
Add APIServerAdapter._bind_api_server_session() and route both agent-entry
paths (_run_agent for /v1/chat/completions + /v1/responses, and the /v1/runs
_run_sync path) through it. The helper hardwires platform="api_server" and
async_delivery=False with no async_delivery parameter to pass, so a future
route added to the API server physically cannot reintroduce the silent
no-op (#10760) by forgetting to mark the channel as non-delivering.
The binding stays request-scoped (cleared per turn), so a session resumed
later on a delivering interface (CLI / gateway platform) re-binds fresh and
is NOT blocked — the no-delivery decision tracks the interface handling the
current turn, never the session.
Inbound image/audio/video payloads were buffered fully into process memory
before being written to the cache, with no size limit. A large upload
(Discord Nitro allows 500 MB) or a remote media URL in an inbound message
pointing at a huge file could spike RAM and OOM-kill the gateway.
Enforce a configurable cap in the shared cache helpers (gateway/platforms/
base.py) so the protection holds across every platform adapter, not one:
- cache_image/audio/video_from_bytes reject oversized payloads before writing
(video was the gap in the original report — now covered).
- cache_image/audio_from_url stream the body, rejecting on an oversized
Content-Length header and re-checking the running total per chunk so an
absent/lying header can't smuggle an unbounded body past the cap.
- Discord's _read_attachment_bytes checks att.size up front, so an oversized
attachment is rejected before any bytes are pulled into memory.
Configurable via gateway.max_inbound_media_bytes in config.yaml (default
128 MiB; 0 disables). No new env var — non-secret config lives in config.yaml.
Salvaged and extended from @sgaofen's PR #13341 (the original report and the
shared-helper approach). Reapplied onto current main (Discord adapter has
since moved to plugins/platforms/discord/), the configurable knob moved from
an env var to config.yaml, and the video cache helper added.

PROBLEM: Mattermost threads can become invalid or enormous, exposing two failure modes: internal scratch/reasoning/commentary displays could leak into persistent Mattermost threads via global display toggles, while rejected threaded user-visible replies could disappear unless every failed send fell back flat. A broad flat fallback would pollute channels with tool/status/progress noise.
SOLUTION: Require explicit Mattermost platform opt-in for scratch displays, keep using the existing notify=True metadata marker for user-visible final text/media/file replies, and allow the Mattermost plugin adapter to flat-fallback only notify-worthy sends whose threaded POST failure looks like a broken root/thread. Keep tool/status/progress and other non-notify sends thread-strict. Add regression tests for display opt-in, notify-only broken-thread fallback, generic API failure suppression, and stream notify metadata.

Session: Mattermost thread 6qg8e9dd1pd9pkhi74xyaa1mry, 2026-06-01.
Own-policy adapters (WhatsApp, WeCom, Weixin, QQBot, Yuanbao) default dm_policy/group_policy to "open", which forwards every sender. The gateway's adapter-trust shortcut in _is_user_authorized blanket-trusted those platforms when no env allowlist was set, so an operator who enabled one with only credentials authorized the entire external network -- the fail-open SECURITY.md section 2.6 forbids ("an allowlist is required for every enabled network-exposed adapter").
Trust the adapter only when its effective policy for the chat type is an actual "allowlist" restriction (the case #34515 was protecting). "open"/"pairing"/anything else falls through to default-deny, where {PLATFORM}_ALLOW_ALL_USERS / GATEWAY_ALLOW_ALL_USERS and the pairing flow remain the explicit opt-ins.
Old Office formats (.xls, .doc, .ppt) were missing from the
SUPPORTED_DOCUMENT_TYPES dict in gateway/platforms/base.py while their
newer counterparts (.xlsx, .docx, .pptx) were included.
Sending an .xls file via Telegram triggers 'Unsupported document type'
and the file is silently dropped instead of being cached and forwarded
to the agent.
Add the three legacy MIME types so these files are handled the same way
as their modern equivalents.
Two fixes for the reported Slack thread approval UX:
1. Slack Block Kit approval/confirm sends silently overflowed the
3000-char section-block cap (flat 2900-char truncation + header +
reason), so long execute_code approvals failed with invalid_blocks
and fell back to the plain-text prompt with no buttons. Budget the
command preview against the rendered fixed parts so blocks never
exceed the cap (send_exec_approval + send_slash_confirm).
2. The text fallbacks told users to reply /approve — which Slack blocks
inside threads and Matrix clients reserve client-side. Add a
typed_command_prefix capability flag on BasePlatformAdapter
(default "/"; Slack and Matrix set "!" to match their existing
bang-prefix rewrite) and use it in the shared fallback prompt
builders (exec approval, update prompt, destructive slash confirm,
expensive-model confirm) plus Matrix's reaction-prompt text.
The slash-confirm text-intercept now also accepts bang-prefixed
replies (!always, !cancel) since those keywords aren't registered
commands and the adapters' rewrite doesn't touch them.
DISCORD_ALLOWED_ROLES was checked by the Discord adapter (_is_allowed_user)
but gateway._is_user_authorized only read DISCORD_ALLOWED_USERS, so
role-authorized users were rejected with "Unauthorized user" at the
gateway layer despite passing the adapter gate.
- Add role_authorized: bool = False to SessionSource
- Add role_authorized param to build_source (base.py)
- Compute _role_authorized in on_message when user passes via role not user ID
- Thread _role_authorized through _handle_message -> build_source
- Check source.role_authorized early in _is_user_authorized (run.py)
Fixes#33952
Terminal tool progress on markdown-capable gateways (Telegram, Slack,
Discord, WhatsApp, Matrix, Weixin, Feishu) renders the full command in a
fenced code block again, in all/new AND verbose modes — gated on the
adapter's supports_code_blocks capability. Plain-text platforms keep the
short truncated preview.
No language tag is emitted: Slack mrkdwn renders a '```bash' fence with
'bash' as a literal first code line, so a bare '```' fence is used, which
renders correctly on every platform that supports blocks.
This restores the #41215 feature (removed in #41950 due to the command
showing in group chats) as the default. For a personal assistant the
command display is desired; the group-chat concern is a preference, not a
vulnerability.
#41215 rendered a terminal tool call as a native ```bash fenced block on
markdown platforms (Telegram, WhatsApp, Slack, and others), showing the full
command with no truncation, in both all/new and verbose modes. That posted
complete shell commands (heredocs, internal paths, destructive commands) into
the chat before the final answer, visible to everyone in it.
This restores the prior behavior: terminal progress shows the short, truncated
preview line that every other tool already uses, capped at tool_preview_length.
The supports_code_blocks capability flag is left in place for future use.
CLI/TUI rendering is a separate path and was unaffected.
Adds a regression test asserting terminal progress renders as a truncated
preview, not a fenced bash block, even on a markdown-capable gateway.
Fixes#41955
Tool-progress now shows a terminal command in a ```bash fenced block —
full command, no surrounding quotes, no label, no 40-char truncation —
instead of the noisy `terminal: "cmd…"` line, on every platform that
renders markdown code blocks (Telegram, Slack, Matrix, WhatsApp, Feishu,
Weixin, Discord). Plain-text platforms keep the compact preview line.
Gated on a new `BasePlatformAdapter.supports_code_blocks` capability
(default False) rather than a hardcoded platform list, so plugin adapters
(Discord lives in plugins/platforms/) opt in by setting the flag. Applies
to both all/new and verbose progress modes, with a safe fallback when the
command arg is missing or blank.
* fix: respect disabled auto-compaction on context overflow
Port from anomalyco/opencode#30749.
When compression.enabled is false, NO automatic compaction trigger may
fire. The proactive token-threshold paths (preflight + post-response
should_compress gate) already honoured the setting, but the three
provider-overflow recovery paths in the agent loop — long-context-tier
429, 413 payload-too-large, and context-overflow — called
_compress_context() unconditionally, silently compressing and rotating
the session against the user's explicit choice.
Add a single guard at the top of the overflow-recovery dispatch: when
compression is disabled and the error is one of those three overflow
classes, surface a terminal error (compaction_disabled: True) telling the
user to /compress manually, /new, switch to a larger-context model, or
reduce attachments. Manual /compress (force=True) is unaffected — it never
enters this loop.
Tests: new TestOverflowWithCompactionDisabled (413 + 400 overflow don't
compress when disabled; control case still compresses when enabled).
Existing overflow-recovery tests updated to enable compaction explicitly
(they verify the recovery fires); fixture defaults flipped to True to
match production (compression.enabled defaults to True).
* fix(gateway): plain text while busy interrupts by default again
busy_input_mode (default 'interrupt') was advertised as the busy-behavior
knob, but a second knob added in 7abd62719 — busy_text_mode, defaulting to
'queue' — short-circuited every plain TEXT message before busy_input_mode
was consulted. Result: plain follow-ups silently queued instead of
interrupting, even with busy_input_mode left at its 'interrupt' default
(regression #38390, silent-queue #31588).
Collapse to one source of truth: busy_input_mode drives text handling.
busy_text_mode is kept only as a legacy explicit override for back-compat
(existing queue setups keep working); when unset it follows busy_input_mode.
All default fallbacks flipped queue->interrupt. The debounce mechanism is
preserved and now keyed off the resolved mode.
Fixes#38390, #31588.
When the agent's reply references a deliverable file path that does not
exist on disk, extract_local_files dropped it from native delivery with
no log line — the most common reason a promised file never arrives over
a messaging platform. Add an INFO log at that drop point so the gap is
visible in gateway.log instead of vanishing.
Also convert the two print() calls in Telegram's send_document /
send_video exception handlers to logger.warning(exc_info=True). print()
writes to stdout, which 'hermes logs' never captures, so outbound upload
failures (oversized files, Bot API rejections) were invisible.
Root-run gateways have $HOME=/root, which is on the MEDIA system-path
denylist, so the gateway silently dropped agent-generated deliverables
under /root (e.g. /root/work/proposal.docx) — the user got a 'here is
your file' reply with nothing attached.
_path_under_denied_prefix now treats the running user's own home as
deliverable: the home tree itself is no longer denied, while the
more-specific denied paths inside it (~/.ssh, ~/.aws, ~/.hermes/.env,
auth.json, config.yaml) stay blocked because they are separate denylist
entries. The exception only matches when the denied prefix IS $HOME, so
a non-root gateway still can't deliver another user's home.
Diagnosis, reproduction, and the failing-case analysis are from
@GodsBoy (#38108 / #38106). Implemented here as the minimal denylist
fix rather than a staging/copy subsystem.

Introduce a typed agent→gateway delivery contract so the gateway (not the
agent) decides how each streaming event is rendered per platform. Moves toward
smart-agent/smart-gateway separation while reproducing today's behavior exactly
in the base class.
- gateway/stream_events.py: typed event vocabulary (MessageChunk/Stop,
Commentary, ToolCallChunk/Finished, LongToolHint, GatewayNotice).
- gateway/stream_dispatch.py: GatewayEventDispatcher routes events through the
adapter; adapters can eat events they can't render (e.g. tool chrome on
plain-text platforms).
- gateway/platforms/base.py: render_message_event + format_tool_event default
hooks reproduce the historical emoji/preview tool formatting and consumer
delegation 1:1; adapters override for native rendering.
- gateway/platforms/telegram.py: send_draft now applies MarkdownV2 (format_message
+ parse_mode) with a plain-text fallback on BadRequest, fixing the jarring
raw-text→formatted shift when the draft finalizes as a real sendMessage.
- gateway/config.py: default streaming transport edit → auto. Safe globally:
adapters without draft support report supports_draft_streaming()==False and
transparently use edit, so only Telegram DMs gain native drafts.
Presentation-only contract — nothing rendered here is persisted to conversation
history, preserving cache/message-flow invariants.
Collapse the per-type observed-media dispatch into one platform-agnostic
cache_media_bytes() helper in gateway/platforms/base.py. Any adapter can now
hand it raw attachment bytes + a filename/MIME hint; it classifies against the
shared MIME registries, routes to the right cache_*_from_bytes helper,
sandbox-translates the path, and returns a CachedMedia with a ready
context_note(). Telegram's observed-group path shrinks to: size-gate, download,
call the helper, annotate. Also dedupes the addressed-media type ladder into
_media_message_type().
Net: contributor's Telegram-only +595 LOC becomes a +210/-32 production change,
with the reusable primitive available to Discord/Slack/Signal/etc.

The extract pipeline (extract_media/extract_images/extract_local_files +
directive strips) can reduce a non-empty tool-using response to empty
text_content with no deliverable attachment. The 'if text_content' send
guard then silently skips delivery: a 'response ready' log with no
'Sending response', no error, and the answer never reaches the user.
- A2: snapshot the pre-extract response; when extraction yields empty text
and no image/local/media attachment, deliver the recovered original from
the post-extract_media body (so a spaced MEDIA path can't leak). Applies
on ALL platforms (supersedes the Discord-only #33842 and the unsafe
raw-fallback #29499).
- A3: loud delivery invariant - a non-empty response that produces nothing
deliverable logs response_delivery_dropped at ERROR; every recovery logs
response_delivery_recovered. No silent drop survives.
- Factor a _strip_media_directives helper for the [[...]] strips; MEDIA
stripping stays owned by extract_media, whose grammar handles spaced and
quoted paths.
- Salvaged + de-scoped the #33842 test harness to all platforms; added
unrecoverable-drop and no-leak regression tests.
extract_media() scanned the full response text without distinguishing
live delivery tags from example paths in fenced code blocks, inline code
spans, and blockquotes. This caused false positives where the agent's
explanation of MEDIA: syntax (or tool output containing example paths)
was stripped from user-visible text and the path was added to the media
delivery list.
Added _mask_protected_spans() helper that replaces protected regions
with equal-length whitespace before regex matching, preserving match
offsets. The helper skips backtick-quoted paths in MEDIA: tags to
maintain existing path extraction behavior.
Fixes#35695
