- Add userToken and userTokenReadOnly (default: true) config fields
- Implement token routing: reads prefer user token, writes use bot token
- Add tests for token routing logic
- Update documentation with required OAuth scopes
User tokens enable reading DMs and private channels without requiring
bot membership. The userTokenReadOnly flag (true by default) ensures
the user token can only be used for reads, preventing accidental
sends as the user.
Required user token scopes:
- channels:history, channels:read
- groups:history, groups:read
- im:history, im:read
- mpim:history, mpim:read
- users:read, reactions:read, pins:read, emoji:read, search:read
- Add shared hasRepliedRef state between auto-reply and tool paths
- Extract buildSlackThreadingContext helper in agent-runner.ts
- Extract resolveThreadTsFromContext helper in slack-actions.ts
- Update docs with clear replyToMode table (off/first/all)
- Add tests for first mode behavior across multiple messages
