- Workspace binary files: use HTTP /v1/files/ endpoint for blob fetch
and download instead of WS text content (fixes corruption). Skip WS
readFile for non-text files, set metadata only for ImageViewer.
- Workspace scope filter: prefix chatID as top-level folder in unscoped
listing so scope switching shows correct tree structure.
- Workspace WS ops: strip chatID prefix from file_name before WS calls
(backend already scopes by chat_id param, was causing doubled path).
- Storage depth: record dirs beyond maxDepth with hasChildren flag before
SkipDir so they appear in tree with lazy-load indicator.
- Remove unused team_workspace_files UNION from ListTaskScopes query.
Major refactoring of the team system with multiple improvements:
## Removed legacy delegation tools
- Delete `delegate.go`, `delegate_async.go`, `delegate_sync.go`, `delegate_events.go`,
`delegate_policy.go`, `delegate_prep.go`, `delegate_state.go`, `delegate_search_tool.go`
- Delete `evaluate_loop_tool.go`, `handoff_tool.go`
- Remove all references and registrations from tool manager and policy
- Clean up TEAM_PLAYBOOK_IDEAS.md and TEAM_SYSTEM.md (moved to docs)
## Rename await_reply → ask_user
- Rename action `await_reply` → `ask_user`, `clear_followup` → `clear_ask_user`
- Rename functions `executeAwaitReply` → `executeAskUser`, `executeClearFollowup` → `executeClearAskUser`
- Update system prompt with stronger wording to prevent model misuse
- Model was confusing "await_reply" with general waiting; "ask_user" is unambiguous
## Fix auto-followup false positives
- Add `HasActiveMemberTasks(ctx, teamID, excludeAgentID)` store method
- Guard `autoSetFollowup()` in consumer: skip when lead has active member tasks
- Prevents auto-followup when lead is orchestrating teammates (not waiting for user)
## Task identifier zero-padding
- Change format from `T-1-xxxx` → `T-001-xxxx` (3-digit minimum)
## Refactor workspace WS handlers to filesystem-only
- Rewrite `teams.workspace.list/read/delete` to use pure filesystem (os.ReadDir/ReadFile/Remove)
- Remove DB dependency from workspace WS handlers
- Consistent with storage handler and workspace tools
- Simplify TeamWorkspaceFile type and frontend hook
## Add team events listing API
- New WS method `teams.events.list` with team_id, limit, offset params
- New HTTP endpoint `GET /v1/teams/{id}/events` with bearer auth
- New `ListTeamEvents(ctx, teamID, limit, offset)` store method
- JOIN with team_tasks for team-wide event filtering
## Extract team access policy
- New `team_access_policy.go` — centralized team tool access control
## Migration 000019: team_id columns
- Add team_id foreign key columns to relevant tables
## Other improvements
- Add team_id propagation through agent loop, tracing, sessions
- Update i18n locale files (en/vi/zh) for new tool labels
- Update frontend builtin-tools page and require-setup component
- Bump RequiredSchemaVersion for migration 000019
* feat(workspace): add team shared workspace for file collaboration
- Add workspace_write and workspace_read tools for agents to share files across team members
- Create team_workspaces DB table with migration 000017 (file metadata, pinning, tags)
- Implement PostgreSQL store layer for workspace CRUD operations
- Add RPC handlers for workspace list/read/delete from web UI
- Build React workspace tab with file listing, content preview, and delete
- Propagate workspace channel/chatID scope through delegation chain
- Auto-allow workspace tools in agent tool policy when agent belongs to a team
- Inject team workspace guidance into system prompt for team agents
- Add /reset command handler for clearing session history
- Harden MCP bridge context middleware to reject headers when no gateway token
- Add i18n strings for workspace UI in en/vi/zh locales
* feat(teams): add comprehensive task management with followup reminders and recovery
- Add task followup/reminder system with auto-set on lead agent reply and auto-clear when user responds on channel
- Add task recovery ticker to re-dispatch stale/pending tasks periodically
- Add task scopes, filtering by status/channel/chatID, and task events
- Add WS RPC handlers for task CRUD, assignments, comments, events, and bulk operations (teams_tasks.go)
- Add task detail dialog, settings UI for followup config, and scope filtering in web dashboard
- Add migrations 000018 (team_tasks_v2) and 000019 (task_followup)
- Extend team_tasks_tool with await_reply, clear_followup actions
- Auto-complete/fail team tasks when delegate agent finishes
- Add workspace file listing and team tool manager enhancements
* docs(teams): add team system architecture and playbook ideas documentation
- Add TEAM_SYSTEM.md with full architecture design covering task management, shared workspace, and delegation engine subsystems
- Add TEAM_PLAYBOOK_IDEAS.md outlining future team coordination layers (playbook, member capabilities, auto-learned patterns)
- Document data models, status flows, tool actions, followup reminder system, task ticker, execution locking, and workspace scope model
* fix(teams): resolve 6 critical bugs in team task system
- Fix unblock SQL: check array_length after array_remove (not before)
- Enforce single-team leadership in team creation
- Add requireLead() for approve/reject tool actions
- Validate cross-team dependency references in blocked_by
- Add team_id to handoff route for multi-team isolation
- Set blocked_by DEFAULT '{}' to prevent NULL array issues
* refactor(workspace): use stable userID as scope key instead of connection UUID
Workspace scope changed from (team_id, channel, chat_id) to (team_id, userID).
Fixes workspace fragmentation across WS tab refreshes and reconnections.
* feat(teams): add V1/V2 versioning with feature gating and optimized prompts
- IsTeamV2() helper gates advanced features (locking, followup, review, audit)
- V2 tool actions rejected for V1 teams with clear error message
- Ticker, gateway consumer, delegation hooks respect version flag
- TEAM.md renders v1/v2 sections conditionally
- Tool descriptions and params optimized (~38% token reduction)
- UI: version toggle in settings, V2 Beta badge, conditional rendering
- i18n: version modal keys for en/vi/zh
* fix(migration): use VARCHAR(255) for user ID columns and add metadata JSONB
- assignee_user_id, user_id, actor_id: TEXT → VARCHAR(255)
- Add metadata JSONB to team_task_comments and team_task_attachments
