* 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
* Security: cap Slack media downloads and validate Slack file URLs
* Security: relax web media fetch cap for compression
* Fixes: sync pi-coding-agent options
* Fixes: align system prompt override type
* Slack: clarify fetchImpl assumptions
* fix: respect raw media fetch cap (#6639) (thanks @davidiach)

* fix(tts): generate audio when block streaming drops final reply
When block streaming succeeds, final replies are dropped but TTS was only
applied to final replies. Fix by accumulating block text during streaming
and generating TTS-only audio after streaming completes.
Also:
- Change truncate vs skip behavior when summary OFF (now truncates)
- Align TTS limits with Telegram max (4096 chars)
- Improve /tts command help messages with examples
- Add newline separator between accumulated blocks
* fix(tts): add error handling for accumulated block TTS
* feat(tts): add descriptive inline menu with action descriptions
- Add value/label support for command arg choices
- TTS menu now shows descriptive title listing each action
- Capitalize button labels (On, Off, Status, etc.)
- Update Telegram, Discord, and Slack handlers to use labels

* fix(gateway): gracefully handle AbortError and transient network errors
Addresses issues #1851, #1997, and #2034.
During config reload (SIGUSR1), in-flight requests are aborted, causing
AbortError exceptions. Similarly, transient network errors (fetch failed,
ECONNRESET, ETIMEDOUT, etc.) can crash the gateway unnecessarily.
This change:
- Adds isAbortError() to detect intentional cancellations
- Adds isTransientNetworkError() to detect temporary connectivity issues
- Logs these errors appropriately instead of crashing
- Handles nested cause chains and AggregateError
AbortError is logged as a warning (expected during shutdown).
Network errors are logged as non-fatal errors (will resolve on their own).

* fix(test): update commands-registry test expectations
Update test expectations to match new ResolvedCommandArgChoice format
(choices now return {label, value} objects instead of plain strings).

Address reviewer feedback: slash commands now use the same
hasExplicitConfig check as regular messages, so unlisted
channels are allowed under groupPolicy: "open" for both
message handling and slash commands.
## Summary
Fix Slack `groupPolicy: "open"` to allow unlisted channels even when `channels.slack.channels` contains custom entries.
## Problem
When `groupPolicy` is set to `"open"`, the bot should respond in **any channel** it's invited to. However, if `channels.slack.channels` contains *any* entries—even just one channel with a custom system prompt—the open policy is ignored. Only explicitly listed channels receive responses; all others get an ephemeral "This channel is not allowed" error.
### Example config
```json
{
"channels": {
"slack": {
"groupPolicy": "open",
"channels": {
"C0123456789": { "systemPrompt": "Custom prompt for this channel" }
}
}
}
}
```
With this config, the bot only responds in `C0123456789`. Messages in any other channel are blocked—even though the policy is `"open"`.
## Root Cause
In `src/slack/monitor/context.ts`, `isChannelAllowed()` has two sequential checks:
1. `isSlackChannelAllowedByPolicy()` — correctly returns `true` for open policy
2. A secondary `!channelAllowed` check — was blocking channels when `resolveSlackChannelConfig()` returned `{ allowed: false }` for unlisted channels
The second check conflated "channel not in config" with "channel explicitly denied."
## Fix
Use `matchSource` to distinguish explicit denial from absence of config:
```ts
const hasExplicitConfig = Boolean(channelConfig?.matchSource);
if (!channelAllowed && (params.groupPolicy !== "open" || hasExplicitConfig)) {
return false;
}
```
When `matchSource` is undefined, the channel has no explicit config entry and should be allowed under open policy.
## Behavior After Fix
| Scenario | Result |
|----------|--------|
| `groupPolicy: "open"`, channel unlisted | ✅ Allowed |
| `groupPolicy: "open"`, channel explicitly denied (`allow: false`) | ❌ Blocked |
| `groupPolicy: "open"`, channel with custom config | ✅ Allowed |
| `groupPolicy: "allowlist"`, channel unlisted | ❌ Blocked |
## Test Plan
- [x] Open policy + unlisted channel → allowed
- [x] Open policy + explicitly denied channel → blocked
- [x] Allowlist policy + unlisted channel → blocked
- [x] Allowlist policy + listed channel → allowed
