* fix(slack): download all files in multi-image messages
resolveSlackMedia() previously returned after downloading the first
file, causing multi-image Slack messages to lose all but the first
attachment. This changes the function to collect all successfully
downloaded files into an array, matching the pattern already used by
Telegram, Line, Discord, and iMessage adapters.
The prepare handler now populates MediaPaths, MediaUrls, and
MediaTypes arrays so downstream media processing (vision, sandbox
staging, media notes) works correctly with multiple attachments.
Fixes#11892, #7536

* fix(slack): preserve MediaTypes index alignment with MediaPaths/MediaUrls
The filter(Boolean) on MediaTypes removed entries with undefined contentType,
shrinking the array and breaking index correlation with MediaPaths and MediaUrls.
Downstream code (media-note.ts, attachments.ts) requires these arrays to have
equal lengths for correct per-attachment MIME type lookup. Replace filter(Boolean)
with a nullish coalescing fallback to "application/octet-stream".

* feat(slack): populate thread session with existing thread history
When a new session is created for a Slack thread, fetch and inject
the full thread history as context. This preserves conversation
continuity so the bot knows what it previously said in the thread.
- Add resolveSlackThreadHistory() to fetch all thread messages
- Add ThreadHistoryBody to context payload
- Use thread history instead of just thread starter for new sessions
Fixes#4470
* chore: remove redundant comments
* fix: use threadContextNote in queue body
* fix(slack): address Greptile review feedback
- P0: Use thread session key (not base session key) for new-session check
This ensures thread history is injected when the thread session is new,
even if the base channel session already exists.
- P1: Fetch up to 200 messages and take the most recent N
Slack API returns messages in chronological order (oldest first).
Previously we took the first N, now we take the last N for relevant context.
- P1: Batch resolve user names with Promise.all
Avoid N sequential API calls when resolving user names in thread history.
- P2: Include file-only messages in thread history
Messages with attachments but no text are now included with a placeholder
like '[attached: image.png, document.pdf]'.
- P2: Add documentation about intentional 200-message fetch limit
Clarifies that we intentionally don't paginate; 200 covers most threads.
* style: add braces for curly lint rule
* feat(slack): add thread.initialHistoryLimit config option
Allow users to configure the maximum number of thread messages to fetch
when starting a new thread session. Defaults to 20. Set to 0 to disable
thread history fetching entirely.
This addresses the optional configuration request from #2608.
* chore: trigger CI
* fix(slack): ensure isNewSession=true on first thread turn
recordInboundSession() in prepare.ts creates the thread session entry
before session.ts reads the store, causing isNewSession to be false
on the very first user message in a thread. This prevented thread
context (history/starter) from being injected.
Add IsFirstThreadTurn flag to message context, set when
readSessionUpdatedAt() returns undefined for the thread session key.
session.ts uses this flag to force isNewSession=true.
* style: format prepare.ts for oxfmt
* fix: suppress InboundHistory/ThreadStarterBody when ThreadHistoryBody present (#13912)
When ThreadHistoryBody is fetched from the Slack API (conversations.replies),
it already contains pending messages and the thread starter. Passing both
InboundHistory and ThreadStarterBody alongside ThreadHistoryBody caused
duplicate content in the LLM context on new thread sessions.
Suppress InboundHistory and ThreadStarterBody when ThreadHistoryBody is
present, since it is a strict superset of both.
* remove verbose comment
* fix(slack): paginate thread history context fetch
* fix(slack): wire session file path options after main merge

Adds thread_ts and parent_user_id to the Slack message footer for thread
replies, giving agents awareness of thread context. Top-level messages
remain unchanged.
Includes tests verifying:
- Thread replies include thread_ts and parent_user_id in footer
- Top-level messages exclude thread metadata
* fix(gateway): increase WebSocket max payload to 5 MB for image uploads
The 512 KB limit was too small for base64-encoded images — a 400 KB
image becomes ~532 KB after encoding, exceeding the limit and closing
the connection with code 1006.
Bump MAX_PAYLOAD_BYTES to 5 MB and MAX_BUFFERED_BYTES to 8 MB to
support standard image uploads via webchat.
Closes#14400
* fix: align gateway WS limits with 5MB image uploads (#14486) (thanks @0xRaini)
* docs: fix changelog conflict for #14486

* fix: use .js extension for ESM imports of RoutePeerKind
The imports incorrectly used .ts extension which doesn't resolve
with moduleResolution: NodeNext. Changed to .js and added 'type'
import modifier.
* fix tsconfig
* refactor: unify peer kind to ChatType, rename dm to direct
- Replace RoutePeerKind with ChatType throughout codebase
- Change 'dm' literal values to 'direct' in routing/session keys
- Keep backward compat: normalizeChatType accepts 'dm' -> 'direct'
- Add ChatType export to plugin-sdk, deprecate RoutePeerKind
- Update session key parsing to accept both 'dm' and 'direct' markers
- Update all channel monitors and extensions to use ChatType
BREAKING CHANGE: Session keys now use 'direct' instead of 'dm'.
Existing 'dm' keys still work via backward compat layer.
* fix tests
* test: update session key expectations for dmdirect migration
- Fix test expectations to expect :direct: in generated output
- Add explicit backward compat test for normalizeChatType('dm')
- Keep input test data with :dm: keys to verify backward compat
* fix: accept legacy 'dm' in session key parsing for backward compat
getDmHistoryLimitFromSessionKey now accepts both :dm: and :direct:
to ensure old session keys continue to work correctly.
* test: add explicit backward compat tests for dmdirect migration
- session-key.test.ts: verify both :dm: and :direct: keys are valid
- getDmHistoryLimitFromSessionKey: verify both formats work
* feat: backward compat for resetByType.dm config key
* test: skip unix-path Nix tests on Windows
When replying to a Slack thread, files attached to the root message were
not being fetched. The existing `resolveSlackThreadStarter()` fetched the
root message text via `conversations.replies` but ignored the `files[]`
array in the response.
Changes:
- Add `files` to `SlackThreadStarter` type and extract from API response
- Download thread starter files when the reply message has no attachments
- Add verbose log for thread starter file hydration
Fixes issue where asking about a PDF in a thread reply would fail because
the model never received the file content from the root message.
Fixes two bugs in Slack tool notification delivery:
1. Tool notifications ignored verbose=false - normalized verbose values so
boolean false/'false' are properly treated as 'off'
2. Thread context lost - Slack outbound adapter now falls back to threadId
when replyToId is missing, and MessageThreadId is set for thread replies
Closes#1333
