`SlackAdapter._is_interactive_user_authorized` (approval / slash-confirm /
clarify Block Kit clicks) and the early pre-fetch gate in the message
handler recovered the runner via `_message_handler.__self__`, which is
None on a multiplexed adapter (closure handler) — so both fell to env-only
auth. The fallback read `SLACK_ALLOW_ALL_USERS` raw from `os.environ` and
its `_env` helper fell through to `os.environ` on a scoped miss: the
DEFAULT profile's allow-all flag / allowlist authorized callers on every
other profile's bot.
- Prefer the wired `set_authorization_check` callback (profile-bound
`_make_adapter_auth_check`) at both sites; keep `__self__` introspection
only for adapters wired without one.
- Env-only fallback reads go through `authz_mixin._platform_gate_env`
(scoped miss under multiplex → "", never os.environ); drop the raw
`os.getenv("SLACK_ALLOW_ALL_USERS")` pre-read.
Reapplies #72657 onto current main (original commit carried a bot
co-author trailer). Same class as Telegram #86296 / #65589.

The two sibling is_bot computations (SessionSource construction and the
thread-history fetch) re-derived bot-ness from bot_id/subtype only, so an
api_human_users post would be human at the drop gate but still flagged
is_bot downstream. Use the single predicate everywhere.
Posts made with a user token (xoxp-) arrive with app_id and no
client_msg_id, so _event_declares_bot_sender dropped them as app traffic;
the only workaround was allow_bots: all. Adds
platforms.slack.extra.api_human_users (SLACK_API_HUMAN_USERS fallback), a
users-only allowlist consulted inside the predicate.
Salvaged from #100964 (users only: an app-id allowlist would also admit
the app's own xoxb bot posts, which share the user+app_id shape).
Every gateway/plugin platform adapter hard-coded aiohttp.ClientSession(trust_env=True)
(~20 sites), so a gateway launched by a Windows Scheduled Task that inherits a stale
HTTP_PROXY (Clash/V2Ray on 127.0.0.1:7890) looped on 'Cannot connect to host' with no
way to opt out short of NO_PROXY hacks per vendor host.
- gateway/platforms/base.py: gateway_trust_env() reads gateway.trust_env (default true);
resolve_proxy_url() skips generic HTTP(S)_PROXY/ALL_PROXY + macOS system-proxy
auto-detect when false (explicit per-platform vars still win).
- All aiohttp ClientSession sites in weixin, qqbot, matrix, line, wecom, slack, sms,
teams, google_chat now pass trust_env=gateway_trust_env(); mattermost + homeassistant
bare sessions gain the same kwarg (intent of #70119 / #56229).
- DEFAULT_CONFIG + cli-config.yaml.example + messaging docs.
- tests/gateway/test_gateway_trust_env.py: config flip + no-bare-literal sweep.

ctx.register_platform_handler(platform, factory) — the generic surface for
plugins to wire native handlers into any platform adapter at connect()
time. Factories receive (native, adapter): the platform's client/app
object (PTB Application, discord.py Bot, slack_bolt AsyncApp, Teams App,
DingTalkStreamClient, aiohttp web.Application) or None for adapters with
no separate native object.
- BasePlatformAdapter._wire_plugin_handlers(native): shared, isolated
invocation helper — a raising plugin cannot block a platform connect.
- All 27 connectable adapters call it: telegram/slack/teams/line/
api_server/msgraph_webhook wire before their dispatch tables freeze;
the rest hook at connect success.
- register_telegram_handler and get_telegram_handler_factories retained
as thin back-compat aliases over the telegram bucket.
- Source-invariant test guarantees every adapter with connect() keeps
calling the hook.
Relay-plane parity: hermes config set / Railway persist YAML booleans
as strings, and _slack_unfurl_kwargs silently dropped them — so
'unfurl_links: "false"' was a no-op on native while working on relay.
Coerce recognized string booleans exactly as _slack_unfurl_hints does;
unrecognized values still drop so junk config keeps Slack's default
instead of accidentally suppressing previews.
Replaces test_send_ignores_non_boolean_unfurl_options (which froze the
dropped-string behavior) with coercion + junk-drop tests.
The wrapper now getattr-defaults _processed_message_ts (object.__new__
adapters in sibling suites lack it), and the reaction-guard source pin
reads _handle_slack_message_impl where the production expression lives.
Follow-up for the #95417 salvage, addressing the review finding: the entry
claim closes the unfurl race but a handler that raises mid-enrichment would
hold the claim forever — neither a Slack retry nor a user edit could ever
re-drive the message. _handle_slack_message is now a thin guard around the
impl that releases only claims taken by the failed invocation itself, with a
warning log so swallowed turns are traceable. Pre-existing claims from a
successful turn are never released. Two failure-path tests pin both sides.
Slack emits `message_changed` for a link unfurl carrying a DIFFERENT event ts
than the original message. That ts legitimately misses the `_dedup` check, so
`_processed_message_ts` is the only guard against it becoming a second user
turn -- but it was only populated at the END of `_handle_slack_message`, after
thread context, permalink resolution and file downloads had all awaited.
An unfurl landing inside that window found the guard empty and was promoted to
a duplicate turn: a spurious "Interrupting current task" banner plus the same
answer posted twice.
Production capture (adminbot, 2026-08-22 02:23:30-31Z, channel C0BF1EYUA9H):
02:23:30.718 message ts=1787365409.908499 dedup_hit=False
02:23:30.737 app_mention ts=1787365409.908499 dedup_hit=True
02:23:31.675 message ts=1787365411.012100 dedup_hit=False <- leaked
subtype=message_changed
The original copy was still resolving two Slack permalinks when the unfurl
arrived 957ms later.
Claim the message ts once every filter has passed and the event is certain to
be delivered, before the slow enrichment awaits. Claiming any earlier (right
after the dedup check) also claims messages the handler then discards, which
breaks summoning the bot by editing "@bot" into a previously ignored message
(tests/gateway/test_slack.py::TestMessageRouting::
test_message_edit_with_new_mention_processed).
Eviction logic is extracted to `_remember_processed_message_ts` so both call
sites share one bounded implementation.
slack_bolt builds a fresh AsyncWebClient for every inbound request and
copies proxy=app.client.proxy into its constructor, where slack_sdk reads
a None/blank proxy *argument* as "unspecified" and reloads HTTP(S)_PROXY
from the environment. aiohttp then treats that env value as an explicit
proxy and skips its own NO_PROXY check, so the adapter's resolved decision
to go direct - a NO_PROXY bypass, or a proxy scheme aiohttp cannot use -
holds on every client except the one authorization spends on auth.test.
The failure looks like a healthy bot: Socket Mode connects, outbound sends
keep working, and every inbound event is rejected with "Failed to authorize
with the given token" - forever, since a failed auth_test_result is not
cached and never retried differently.
Re-apply the resolved proxy through AsyncApp(before_authorize=...), which
bolt inserts before the authorization middleware: the request-scoped client
already exists there and has not been used yet. Assigning the attribute
post-construction is the only way to express "no proxy" to slack_sdk.

Slack sends an authored message twice: flat in `event.text` and structurally
in `event.blocks`. The blocks are rendered so quoted and forwarded content is
not lost, and whatever the render carries beyond the flat text is appended to
the message. That comparison had several ways to fail on the *same* sentence,
each of which showed the author their own words a second time:
1. HTML entities — the flat copy escapes `&`/`<`/`>` while `blocks[].link.url`
stays raw, so any link with query parameters (every "Copy link" on a
thread) mismatched.
2. Permalink unfurls — the live inbound path skips `is_msg_unfurl`
attachments, thread/parent hydration did not, so the linked message's body
was appended again.
3. The Block Kit dump — it serialized the authored `rich_text` alongside the
UI blocks it exists for, and its allowlist drops `url`, so the sentence
reappeared with every link removed.
4. Unknown inline elements — the renderer knew eight types and silently
dropped the rest. A pasted message permalink arrives as `message_mention`,
so the link vanished from the render and the sides stopped comparing equal.
5. `message_mention` without a url — `url` is optional on that element while
`channel_id` and `message_ts` are not, so the element rendered as nothing
and the sentence came back with a blank in the link's place.
6. `date` elements — `fallback` and `url` are both optional, and the flat
`<!date^…>` form was never read down to what the rich text renders.
7. Labelled mentions — Slack may attach a label (`<@U…|name>`,
`<#C…|general>`, `<!subteam^S…|@marketing>`, `<!here|@here>`) in the flat
text while the blocks carry the bare id. The bot's own mention is one of
these, and stripping only its bare form left it in the flat copy.
8. Autolink schemes — only `https` and `mailto` were matched, so a `tel:` link
kept its angle brackets and mismatched too.
Unknown inline types are now read by their `url`/`text`/`fallback` so a type
Slack adds later still renders, and `team`, `color` and a fallback-less `date`
render into the flat form Slack sends. Every field is read as a string or
not at all: Block Kit carries text as an object in many places, and a
non-string one reaches the renderer's `str.join` and raises there, which
costs the whole message. `channel_id` and `message_ts` are the
permalink's own components, so a url-less `message_mention` renders the
permalink's tail; the workspace host and the thread query cannot be rebuilt
from the element, so a permalink on either side is reduced to that same tail.
Canonicalization is used for matching only -- the authored text still reaches
the agent verbatim, so a mistake here can cost an unrendered element, never an
altered or missing message.
An element carrying neither a url nor a label still renders as nothing, and a
message containing one is still appended twice. Suppressing such a render was
tried and is worse: an app message whose body lives only in the blocks
disappears, and a forwarded quote is dropped. Genuinely additional content --
quotes, lists, code blocks, attachments, interactive bot blocks -- is
unaffected throughout.
Tests cover both merge sites (live inbound and thread hydration) and the
negative cases.
Adapter ingress derives a session key BEFORE the runner stamps
source.profile in _make_profile_message_handler, so the namespace fell
back to the active profile and every bot in a multiplexed gateway
produced agent:main:<platform>:<chat>. A Telegram private chat reports
the user's own id as chat.id, identical for every bot, so two profiles
sharing one human collapsed onto a single lane: _pending_text_batches,
_active_sessions, the busy-session guard and _post_delivery_callbacks are
all keyed on that string. A day of production logs across two bots shows
60 flushes, none carrying the secondary profile's namespace.
set_owner_profile records credential ownership on the adapter and
_session_key_profile resolves the namespace as source.profile ->
_owner_profile -> the session store's resolver, so a secondary adapter
keys into its own namespace even before the source is stamped. Stamped
sources keep priority, so relay/connector ingress, which routes per event
rather than per credential, is unchanged. _configure_profile_adapter
installs the owner alongside the other handlers, covering startup and
reconnect.
Every candidate is type-checked as a non-blank str, and every attribute
read goes through getattr: adapters are routinely built without
BasePlatformAdapter.__init__, and a duck-typed session store returns a
truthy non-string that would otherwise be interpolated into the key as
agent:<MagicMock ...>:.
Also routes the four call sites that passed no profile at all (feishu
media batches, raft, slack _session_key_for_source, telegram photo
batches) through the same resolver.
test_multiplex_busy_input_mode's secondary-adapter busy case seeded
_active_sessions with the unstamped agent:main: key, asserting the
pre-fix collapse. It now seeds the lane the profile-owned adapter
actually derives.
A primary adapter has no owner and an unstamped source, so it resolves
exactly as before; with multiplex_profiles off the resolver returns None
and every key is byte-identical to today's.
Slack session keys include the workspace id since #70190, but the kanban
notifier rebuilds the wake source from a subscription row that has no scope
column, so every terminal-event wake keyed without the workspace.
The legacy-key adoption shipped in the same change (`_legacy_slack_session_key`,
`_recovered_row_matches_source_scope`) resolves that unscoped key onto the same
session_id, so the wake passes the busy guards that are keyed by routing key
(`_active_sessions`, `_running_agents`) and only collides afterwards, on session
id, under the per-session turn lease (#64934) — which serializes it behind the
live turn's flush. On a live Slack gateway that shows up as a duplicate run on
one task plus 400+s of waiting before the woken turn starts.
Same failure mode as #56580 / #72191 (chat_type), one field over, and it needs
no schema change: `_thread_metadata_for_source()` already stamps
`slack_team_id`, the notify subscription persists that dict as
`delivery_metadata`, and the notifier already unpacks it. Rows written by
`kanban_tools._maybe_auto_subscribe` carry no workspace, so fall back to the
adapter's channel → workspace map via `scope_id_for_chat()`, read with getattr
so adapters opt in and unscoped platforms' keys stay byte-identical. Slack
answers it from `_remember_channel_team`, which drops channels claimed by two
workspaces, so an unknown or ambiguous channel degrades to today's behavior
instead of guessing wrong.
Also adds the contributor email mapping the attribution check requires.

Adds platforms.slack.extra.native_task_cards: when enabled, live tool
calls render as Slack-native plan/task cards via chat.startStream /
chat.appendStream (task_display_mode: plan, task_update chunks) instead
of text/edit progress bubbles. ID-bearing tool_start/tool_complete
callbacks correlate concurrent same-name tool calls correctly; any
native API failure falls back to one continuously edited text update.
The stream is stopped exactly once when the turn finalizes.
Salvaged from PR #29496 onto current main (TurnRunner/TurnContext seam);
closes#29483.
Slack's Agents & AI Apps feature ships a native streaming surface that
renders a live-typing message instead of the edit-based progressive
updates the adapter used until now.
The adapter now implements the existing draft-streaming interface:
- supports_draft_streaming() opts in whenever the app is connected and
native streaming hasn't been detected as unavailable.
- send_draft() starts a stream on the first frame (chat.startStream,
anchored to the resolved thread_ts, with recipient_team_id/user_id
for channel streams) and appends only the delta on subsequent frames
(chat.appendStream is append-only). The consumer's trailing cursor
glyph is stripped before delta computation.
- Unlike Telegram drafts (ephemeral, replaced by a real sendMessage),
a Slack stream IS the final message. send() therefore intercepts the
turn-final delivery for a chat with an active stream whose streamed
text is a prefix of the final content, and seals it via
chat.stopStream with the remaining delta instead of posting a
duplicate. Rich Block Kit (when enabled) is applied to the sealed
message via chat_update, mirroring the finalize path in edit_message.
- Feature-gate errors from chat.startStream (not_allowed,
missing_scope, unknown_method, ...) are cached on the adapter so
subsequent runs skip straight to edit-based streaming with a single
warning naming the fix (enable Agents & AI Apps for the app);
transient errors only disable drafts for the current run via the
consumer's existing send_draft failure handling.
- Segment breaks (new draft_id) and disconnect() seal any open stream
so chats are never left with a dangling live-typing indicator.
No consumer or config changes: streaming.transport auto/draft now
lights up native streaming on Slack through the same interface
Telegram drafts use, and the edit-based path remains the fallback.
Slack Web API calls return `SlackResponse`/`AsyncSlackResponse`, which are
mapping-like but not `dict` subclasses, so every `isinstance(resp, dict)`
gate took its "unexpected shape" branch at runtime: user and channel names
collapsed to raw IDs, every user resolved as a non-bot (defeating the
allow_bots loop guard), ephemeral replies were reported as failures, and
uploads/caption fallbacks lost their message_id.
Normalize responses through a single `_slack_response_payload()` helper
(dict passes through, SDK response yields `.data`, anything else yields
`{}` so callers keep their fallbacks) and use it at every call site.
Existing Slack tests injected plain dicts, which is why the defect was
invisible; the new tests run each behavioral case against a real
`AsyncSlackResponse` as well.
_humanize_user_mentions rewrites <@UID> to @DisplayName by passing the
resolved name as re.sub's replacement, where re parses it as a template.
A display name is arbitrary user-set text, so the escapes in it are the
user's characters, not regex syntax:
dev\ops -> re.error: bad escape \o
a\1b -> re.error: invalid group reference 1
\g<0> -> expands to the whole match, silently putting the opaque
<@UID> back — the token this method exists to remove
The trigger-text call site sits in _handle_slack_message outside any try,
and both Bolt event handlers await it bare, so the raise takes the whole
inbound message down: every message mentioning that person is dropped.
Pass the replacement as a function instead — re does no template parsing
on the return value, so the name lands verbatim. Same shape the Matrix
adapter already uses for its outbound mention rewrite.
PlatformEntry.check_fn served three contradictory roles: adapter-creation
gate, config auto-enablement gate, and status display. Plugins had to pick
one function for all three:
- Active installer as check_fn (discord/slack/telegram/matrix/dingtalk/
feishu): every status display could pip-install SDKs as a side effect
(the desktop 94% boot-loop class).
- Passive probe as check_fn (teams, wecom_callback): create_adapter()
returned None before connect() could lazy-install, so the SDK never
installed (#79812 deadlock; wecom_callback's platform.wecom_callback
LAZY_DEPS entry was dead code).
The split makes both call sites correct by construction:
- check_fn is now contractually PASSIVE (probe only, never installs).
- New optional PlatformEntry.ensure_deps_fn is the ACTIVE installer;
create_adapter() runs it exactly when check_fn is False — the platform
is enabled+configured and the gateway is about to connect it.
- Config enablement keeps a configured platform whose deps are missing
but installable; the install itself is deferred to create_adapter().
- Status surfaces (_platform_status, hermes status) read only the
passive probe and can never trigger pip.
Migrated all lazy-installable platform plugins to the split; platforms
with no optional deps (irc/ntfy/buzz/simplex/line/a2a/...) are unchanged
— no ensure_deps_fn means a False check_fn stays a hard block.
wecom_callback gains a working installer for the first time.
Builds on @xxxigm's #79812 (both commits cherry-picked with authorship
preserved), reworking the check_fn swap into the two-field split so the
Teams fix doesn't reintroduce install-on-status.
- discord/telegram/slack/matrix standalone senders read bot tokens via
get_secret (in-turn: they run inside an installed scope — cron scheduler
and delegate spawns propagate it), never borrowing another profile's
env-bridged token under multiplex.
- telegram webhook-secret and matrix access-token/password startup reads
use the Slack pattern (#59739): get_secret, falling back to os.environ
only on UnscopedSecretError.
Follow-up to PR #70238. Remove 'free-response channel' and
'authorization' jargon from the model-facing prompt. Collapse the
triple-negative 'do not ask / do not reject / do not stay silent'
into a single directive. ~70 tokens vs ~175 in the contributor's
version, same semantics.
Two related Slack delivery fixes for send_message text sends:
- Route Slack text delivery through _send_via_adapter so the live
in-process gateway adapter (multi-workspace aware, channel→client
mapping, adapter-side gates) is preferred, with the plugin's
_standalone_send as the out-of-process fallback — matching how the
media path already behaves.
- _standalone_send: SLACK_BOT_TOKEN can be a comma-separated list in
multi-workspace installs and slack_tokens.json carries OAuth
per-workspace tokens; the standalone Web-API path used to send the
literal comma-joined string, which Slack rejects as invalid_auth.
Try each token individually, retrying on token-scoped errors
(invalid_auth / not_in_channel / channel_not_found …) and stopping on
terminal ones. User-DM resolution (U…/W… targets) also tries each
token.
Adapted from #47547 by @replygirl — the original patched the legacy
tools/send_message_tool.py::_send_slack helper, which moved to the
Slack plugin's _standalone_send in #41112.
Salvaged from #47547
Previously, Slack sessions and the channel directory stored raw channel
IDs (e.g. C0ATFHY907L) as chat_name, making it impossible for operators
to identify channels in send_message listings or session data.
Changes:
- Add _channel_name_cache and _resolve_channel_name() to SlackAdapter
that calls conversations.info (channels) or users.info (DMs) with
in-memory caching to avoid repeated API calls
- Use resolved names in _handle_slack_message() build_source() calls
- Use cached names in _seed_assistant_thread_session()
- Enrich session-sourced entries in channel_directory._build_slack()
by cross-referencing API results and falling back to conversations.info
+ users.info for DMs and private channels not in the bot's scope
Fixes: channel directory and session origins now show readable names
like 'general' or 'John Doe' instead of 'C0xxx' / 'D0xxx'.
Follow-up to the #51899 pick, folding in the config-bridge half of the
competing PR #46925 (@bhanusharma, earliest submitter for the
ignored-channel gate):
- _apply_yaml_config: translate config.yaml slack.ignored_channels into
SLACK_IGNORED_CHANNELS (list or CSV), env-var-wins like every other
bridged Slack key.
- SlackAdapter._slack_ignored_channels / gateway.run's
_slack_ignored_channels_from_gateway_config: fall back to the
SLACK_IGNORED_CHANNELS env var when PlatformConfig.extra carries no
value, so top-level slack: blocks (which flow through the env bridge,
not extra) are honored at both the adapter and runner gates.
- conftest: force-clear SLACK_ALLOWED_CHANNELS / SLACK_IGNORED_CHANNELS /
SLACK_DISABLE_DMS between tests (config-loader side-effect leak class).
- Tests: env-bridge translation + precedence in test_config.py, env
fallback + extra-wins in test_slack_runner_ignored_channels.py.
Credit: #46925 by @bhanusharma proposed the same gate with the YAML→env
bridge; #51899 (picked as the base) carries the wider outbound/runner
coverage. Closes#46925 as consolidated here with first-submitter credit.
Hermes already identifies itself on outbound calls to model providers
and monitoring endpoints — see hermes_cli/models.py and
plugins/model-providers/gmi/__init__.py
("Attribution so GMI can identify traffic from Hermes Agent"). The
Slack adapter is the one outbound surface that doesn't carry the
same identifier, so HermesAgent-driven Slack traffic is
indistinguishable from any other Bolt-Python app at the Slack
platform layer.
This sets `user_agent_prefix=f"HermesAgent/{_HERMES_VERSION}"` on the
AsyncWebClient instances constructed in gateway/platforms/slack.py
and threads them through AsyncApp via its `client` kwarg. Both
kwargs are first-class in slack-sdk and slack-bolt; no new
dependencies. Resulting header looks like:
HermesAgent/<version> Python/3.x slackclient/3.x ...
No behavioral change for users — the Slack API ignores User-Agent
semantically; it lands in logs and analytics. Reversible.
Tests in tests/gateway/test_slack.py:
- TestSlackUserAgent pins the prefix shape and runs connect()
end-to-end (multi-token config) to assert every AsyncWebClient
carries the prefix and AsyncApp receives the pre-built client.
- TestSlackProxyBehavior fakes updated to tolerate the new kwargs
via **_kwargs so they don't break on future passthroughs.
.get("key", {}) only applies the default when the key is ABSENT.
When the key exists with value None (null in JSON), .get() returns
None and the subsequent .get() raises AttributeError.
Fix: replace .get("key", {}).get(...) with (.get("key") or {}).get(...)
which handles both missing keys AND None values.

Blank (or whitespace-only) answers to the home-channel prompt in the
interactive setup wizards previously left any previously saved
*_HOME_CHANNEL / *_HOME_ROOM env value in place, so operators could not
clear a stale home channel by re-running setup. Strip the prompt input
and call remove_env_value() on blank answers across the Discord, Slack,

Fixes#12423
Salvaged from #58421
The C13 log-noise test (merged while this branch was in flight) builds a
bare SlackAdapter without __init__; the new _channel_teams ambiguity map
crashed it. getattr-guard, same pattern as the sibling defensive inits.
Salvaged from #59742 (downloads half only). Main already resolves the
event-level team id from the channel→workspace cache before downloads
(the file-EVENT half was covered by #30456), but when neither the event
nor the cache knows the workspace, both download helpers silently fell
back to the PRIMARY workspace token — Slack then returns an HTML login
page instead of file bytes for any non-primary workspace file.
Slack private file URLs embed the owning workspace id
(files-pri/<TEAM_ID>-<FILE_ID>/...), so _resolve_download_token now
prefers: explicit team_id -> URL-embedded team id -> primary token.
Both _download_slack_file and _download_slack_file_bytes route through
it.
Deferred from #59742 (out of this correctness cluster's scope): the
channel→team disk persistence, the pre-send conversations.info probe
loop, and the thread-file ingestion feature.
Reapplied from #59742 by @benjamin2026-dot onto the current adapter
(original targeted the pre-#30456 download sites).
Widen #48476's fence guarantees to the two splitters that still emitted
fence-broken chunks:
* GatewayStreamConsumer._split_text_chunks (fallback final send): close
the orphaned ``` at each chunk boundary and reopen it — with the
original language tag — on the next chunk, mirroring
BasePlatformAdapter.truncate_message's contract. Headroom is reserved
so balanced chunks stay within the platform limit.
* Slack block_kit._split_text (3000-char section chunking): same
close/reopen balancing for mrkdwn section text carrying fences.
With these, every chunk boundary — non-streaming send
(truncate_message), streaming overflow (_truncate_for_stream via
adapter.truncate_message per #45938), fallback final
(_split_text_chunks), final-send balance (ensure_closed_code_fences),
and Block Kit section splits — delivers fence-balanced chunks.
Regression tests probe each path with fenced fixtures, assert per-chunk
balance, limit compliance, language-tag reopening, and prose passthrough.
Slack's Block Kit `markdown` block accepts standard markdown (tables,
headers, task lists, fenced code with syntax highlighting, links) and
lets Slack translate it natively — eliminating the lossy markdown→mrkdwn
conversion for the rendered layout. Enable via
platforms.slack.extra.markdown_blocks.
Safety rails added on top of the original design:
* opt-in (default off) — Slack documents the block for 'apps that use
platform AI features' and does not guarantee availability across all
app types / surfaces, so unconditional adoption is not safe yet
* the mrkdwn-converted text field is ALWAYS kept as the
notification/search/accessibility fallback
* content over Slack's 12k cumulative markdown-block cap declines to the
rich_blocks renderer / plain text path
* the existing block-rejection retry (invalid_blocks / msg_too_long /
too_many_blocks) re-sends the plain mrkdwn payload, so an unsupported
surface degrades gracefully instead of dropping the message
* when both modes are enabled, markdown_blocks is preferred over the
local rich_blocks renderer; rich_blocks remains the fallback
Adapted from #8554 by @shivasymbl — the original patched the deleted
gateway/platforms/slack.py and switched unconditionally; reimplemented
against the plugin adapter's _maybe_blocks/sanitize_blocks pipeline.
Fixes#8552.
Slack mrkdwn has no table syntax — GFM pipe tables render as literal-pipe
noise with a raw |---|---| separator row. Wrap detected tables in ```
fences so they render as monospace preformatted text, and pad cells to
per-column max display width (East-Asian Wide / Full-width chars counted
as 2 columns) so columns stay aligned even with CJK content.
Tables already inside fenced code blocks are left untouched, and the
emitted fences carry no language tag so they compose with the
lang-tag-strip pass. This covers the plain-mrkdwn text path; the opt-in
rich_blocks path already renders native Block Kit table blocks.
Reapplied from #16648 by @kylezh — the original patched
gateway/platforms/slack.py, which was migrated to
plugins/platforms/slack/adapter.py in the plugin migration.
Fixes the non-rich_blocks table path described in #8552.
Slack's mrkdwn parser can fail to recognize the closing * of a bold span
when it is immediately preceded by a non-word character (), ], }, ., :,
em-dash, ...), mis-rendering the span and in reported cases truncating
the rest of the message. Insert a zero-width space (U+200B) between the
last character and the closing * whenever the last character is not
alphanumeric or underscore.
Reapplied from #35144 by @gonzalofrancoceballos — the original patched
gateway/platforms/slack.py, which was migrated to
plugins/platforms/slack/adapter.py in the plugin migration.
Slack's mrkdwn does not strip the optional language tag from fenced
code blocks like GitHub-flavored markdown does — it renders
```text\nfoo\n``` as a code block whose literal first line is "text".
The agent emitted ```text fences around raw command output, which
surfaced "text" as the first line of every such block.
Drop the tag from the opening fence in format_message() before stashing
the block behind a placeholder. Stripping only fires for a genuine
opening fence — a ``` at the start of a line, tagged with a single
token (no spaces or backticks) — and the original line ending is
preserved. The fence-protection regex deliberately matches loosely, so
a mid-line ``` (e.g. an inline ```span``` wrapping across a newline)
can be grouped as an "opening fence" whose first line is real content;
differential fuzzing against the pre-change formatter (40k generated
messages) confirms the only behavioral delta is the tag strip itself.
The Block Kit renderer is unaffected: render_blocks() intercepts fences
itself before mrkdwn_fn is applied, so this only changes the mrkdwn
surfaces that still go through format_message() — the plain-text
fallback field (notifications, search indexing, accessibility),
slash-command ephemeral replies, and standalone cron delivery.
Originally written against gateway/platforms/slack.py; ported to
plugins/platforms/slack/adapter.py after the adapter migration in
5600105478.
Manually verified against a live Slack workspace (pre-migration
adapter; the ```text case strips identically) — code blocks no longer
carry a literal "text" first line.
format_message unescapes already-escaped input before re-escaping, so that
pre-escaped text doesn't get double-escaped. That unescape was three
sequential str.replace calls, which re-scan each other's output:
"&lt;" --(& -> &)--> "<" --(< -> <)--> "<"
The & produced by the first replace pairs with the following "lt;" and
decodes a second time. "&lt;" is the wire form of the literal text
"<", so the text is silently destroyed: Slack receives "<" and renders
"<". Anyone writing about HTML or markup ("&lt;b&gt;" -> "<b>")
loses their literal text, with no error.
re.sub scans left-to-right and never re-scans its own replacements, so a
single pass fixes it. The escape pass on the next line is left untouched --
it is correctly ordered (& first, so the &s it inserts aren't re-escaped).
Only the double-decode cases change; every other input is byte-identical
before and after. This is the same round-trip invariant the neighbouring
test_pre_escaped_{ampersand,lt,gt}_not_double_escaped tests already assert,
extended to the case they miss. Affects the plain mrkdwn path (send,
edit_message) and Block Kit sections, which route section text through
format_message.
Build the full reaction pipeline on top of the #29916 base:
- Opt-in gate: slack.reaction_triggers (default OFF — reaction events
stay acked-and-dropped so busy channels don't wake the agent on every
emoji). 'true' routes reactions on the bot's OWN messages; an explicit
emoji-name list routes those emojis from any message (handoff flows).
- reaction_removed events now route too, distinguished by the
cross-platform text convention reaction:added:<emoji> /
reaction:removed:<emoji> (matches the Feishu and Photon adapters, so
agents and skills see one shape everywhere).
- Authorization: the reactor becomes the synthesized message's user, so
the early _is_user_authorized gate and allowed_channels whitelist
apply exactly as for typed messages. _hermes_force_process only skips
the mention requirement (a reaction on the bot's own message is
definitionally addressed to the bot), mirroring Feishu/Photon.
- Gateway hooks (#33111 by @johnkattenhorn): every human reaction on a
message item fires reaction:added / reaction:removed through the new
BasePlatformAdapter.set_reaction_handler → GatewayRunner
._handle_reaction_event → HookRegistry.emit, independent of the
routing opt-in. Documented in hooks.md.
- Channel handoff (#45265 by @Kev-fs): slack.reaction_trigger_target
routes the reaction turn to a configured channel (top-level via
_hermes_no_thread_response + reply-anchor suppression in
gateway/platforms/base.py) or C123:<ts> thread.
- Manifest: reaction_removed event subscription added alongside
reaction_added/reactions:read.
- Docs: slack.md Reaction Triggers section; hooks.md event table rows.

handling — same plumbing class, superseded by this consolidated shape).

Slack reaction_added events were explicitly acked and dropped, so a user
reacting to a bot message (👍 to approve, ✅ to acknowledge) produced
nothing. Forward them through the normal message pipeline as synthesized
MessageEvents whose text is the reaction emoji (translated to unicode
for common names), keeping the downstream auth gate, thread-context
fetch, dedup, and skill routing unchanged.
- Self-reactions and non-message items are dropped; reactions on
messages not sent by this bot are dropped (Feishu-adapter parity).
- The reacted-to message's thread parent becomes the synthesized
thread_ts so the reaction lands in the same session as a reply would.
- Manifest gains reactions:read scope + reaction_added bot event.
Salvaged from PR #29916 by @bpross.
Related: #33111, #44508, #45265 (same cluster).
Salvaged from PR #45702 (heartbeat half). A multi-minute turn showed a
static 'is thinking...' assistant status that reads as stuck and provokes
mid-turn 'you there?' pings. Derive the fallback status label from the
turn's elapsed time (>=30s → 'still working… (NmSSs)'), riding the
existing _keep_typing refresh — zero extra API calls.
Ported onto the current plugin adapter: the start time rides the tracked
_active_status_threads entry (workspace-scoped key), so it shares the
existing bounds/eviction and resets when stop_typing clears the status.
Explicit live-status phrases (set_status_text) and configured
typing_status_text always win; only the built-in default label changes.
The PR's other half (top-level channel follow-up coalescing) is NOT
included — dispatch semantics changed on main (busy-input active-turn
redirect, #30170 demotion) and need a fresh design pass.

Follow-up hardening on top of the C14 cherry-picks (#57860/#44026/#66742/#60009):
- Slack file downloads (_download_slack_file/_download_slack_file_bytes)
now require an https URL on a Slack CDN host (files.slack.com,
*.slack.com Enterprise Grid, *.slack-files.com legacy shares) before
attaching the bot token. url_private/url_private_download only ever
point at the Slack CDN, so a forged file object from a malicious
workspace app or compromised event stream pointing the Bearer-token
download at an arbitrary PUBLIC host (token exfiltration) is now
refused — a hole #44026's generic private-IP SSRF check alone could
not close.
- The same two download paths now use create_ssrf_safe_async_client
(from #57860) so the preflight-validated hostname is resolved once,
validated, and dialed by IP — closing the DNS-rebinding TOCTOU window
for the token-bearing inbound fetches as well.
- #60009's slack_tokens.json permission warning is generalized into
utils.warn_if_credential_file_broadly_readable() (POSIX-only,
fail-quiet) and wired into the other read path with the same gap:
google_chat's load_user_credentials(). google_chat already writes
0o600 via _write_private_json; the read-time warning covers
hand-provisioned/legacy files. Nothing in-repo writes
slack_tokens.json (user/OAuth-provisioned), so there is no write
path to chmod for Slack.
Security tests both directions: non-CDN/lookalike/http URLs and
connect-time DNS rebinds are blocked before any TCP connect; real
files.slack.com, Enterprise Grid, and slack-files.com URLs still reach
the network layer; 0o600 files stay silent while 0o644/0o640 warn with
a chmod hint. A/B: all 10 new download-guard tests fail with the
hardening reverted and pass with it applied.
The OAuth multi-workspace token file contains plaintext bot tokens for
all saved Slack workspaces. Unlike the Google Chat adapter which sets
0o600 when writing credentials, the Slack token file has no permission
enforcement — a default umask 022 makes it world-readable.
Fix: check file permissions on read and emit a warning log with remediation
instructions if the file is group- or world-readable.
`SlackAdapter._fetch_thread_context` formats each prior thread message as
`{name}: {msg_text}` and joins them with newlines into the block the call
site prepends *raw* into the model turn (`text = thread_context + text`).
Both fields are attacker-influenceable — any thread participant sets their
own Slack display name and message text — and neither was neutralized, so
an embedded newline let a thread message break out of its line and pose as
a fresh markdown section (a fake "## SYSTEM" / "## Override" heading) inside
the context the model reads when first mentioned mid-thread.
This is the same indirect-prompt-injection vector already closed for the
sibling untrusted sinks: the sender-name prefix
(`neutralize_untrusted_inline_text`), the reply quote, and the relay
channel-context renderer. The Slack thread-context backfill — the default
whenever the bot is mentioned in a thread with no active session — was the
missed sink. (The existing `[unverified]` tagging marks *who* a message is
from; it does nothing about newline structure, so an authorized sender can
inject just as easily.)
Flatten both fields with `neutralize_untrusted_inline_text` before
interpolation. The body uses `max_chars=0` so message text is not truncated
(thread context caps the message *count*, never per-message length); the
display name keeps the default bound. `parent_text` keeps the raw message
(its own reply-context sink neutralizes separately). A well-behaved message
is preserved byte-for-byte.
Adds a regression test covering a hostile display name, a hostile message
body, benign passthrough, and the no-truncation guarantee.
