# Team Coordinate v2

Universal team coordination skill: analyze task -> generate role-specs -> dispatch -> execute -> deliver. Only the **coordinator** is built-in. All worker roles are **dynamically generated** as lightweight role-spec files and spawned via the `team-worker` agent.


## Architecture

```
+---------------------------------------------------+
|  Skill(skill="team-coordinate-v2")                 |
|  args="task description"                           |
+-------------------+-------------------------------+
                    |
         Orchestration Mode (auto -> coordinator)
                    |
              Coordinator (built-in)
              Phase 0-5 orchestration
                    |
    +-------+-------+-------+-------+
    v       v       v       v       v
 [team-worker agents, each loaded with a dynamic role-spec]
  (roles generated at runtime from task analysis)

  Subagents (callable by any worker, not team members):
    [discuss-subagent]  - multi-perspective critique (dynamic perspectives)
    [explore-subagent]  - codebase exploration with cache
```

## Role Router

This skill is **coordinator-only**. Workers do NOT invoke this skill -- they are spawned as `team-worker` agents directly.

### Input Parsing

Parse `$ARGUMENTS`. No `--role` needed -- always routes to coordinator.

### Role Registry

Only coordinator is statically registered. All other roles are dynamic, stored as role-specs in session.

| Role | File | Type |
|------|------|------|
| coordinator | [roles/coordinator/role.md](roles/coordinator/role.md) | built-in orchestrator |
| (dynamic) | `<session>/role-specs/<role-name>.md` | runtime-generated role-spec |

### Subagent Registry

| Subagent | Spec | Callable By | Purpose |
|----------|------|-------------|---------|
| discuss | [subagents/discuss-subagent.md](subagents/discuss-subagent.md) | any role | Multi-perspective critique (dynamic perspectives) |
| explore | [subagents/explore-subagent.md](subagents/explore-subagent.md) | any role | Codebase exploration with cache |

### Dispatch

Always route to coordinator. Coordinator reads `roles/coordinator/role.md` and executes its phases.

### Orchestration Mode

User just provides task description.

**Invocation**: `Skill(skill="team-coordinate-v2", args="task description")`

**Lifecycle**:
```
User provides task description
  -> coordinator Phase 1: task analysis (detect capabilities, build dependency graph)
  -> coordinator Phase 2: generate role-specs + initialize session
  -> coordinator Phase 3: create task chain from dependency graph
  -> coordinator Phase 4: spawn first batch workers (background) -> STOP
  -> Worker executes -> SendMessage callback -> coordinator advances next step
  -> Loop until pipeline complete -> Phase 5 report + completion action
```

**User Commands** (wake paused coordinator):

| Command | Action |
|---------|--------|
| `check` / `status` | Output execution status graph, no advancement |
| `resume` / `continue` | Check worker states, advance next step |

---

## Coordinator Spawn Template

### v2 Worker Spawn (all roles)

When coordinator spawns workers, use `team-worker` agent with role-spec path:

```
Task({
  subagent_type: "team-worker",
  description: "Spawn <role> worker",
  team_name: <team-name>,
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <session-folder>/role-specs/<role>.md
session: <session-folder>
session_id: <session-id>
team_name: <team-name>
requirement: <task-description>
inner_loop: <true|false>

Read role_spec file to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery) -> role-spec Phase 2-4 -> built-in Phase 5 (report).`
})
```

**Inner Loop roles** (role has 2+ serial same-prefix tasks): Set `inner_loop: true`. The team-worker agent handles the loop internally.

**Single-task roles**: Set `inner_loop: false`.

---

## Completion Action

When pipeline completes (all tasks done), coordinator presents an interactive choice:

```
AskUserQuestion({
  questions: [{
    question: "Team pipeline complete. What would you like to do?",
    header: "Completion",
    multiSelect: false,
    options: [
      { label: "Archive & Clean (Recommended)", description: "Archive session, clean up team" },
      { label: "Keep Active", description: "Keep session for follow-up work" },
      { label: "Export Results", description: "Export deliverables to target directory, then clean" }
    ]
  }]
})
```

### Action Handlers

| Choice | Steps |
|--------|-------|
| Archive & Clean | Update session status="completed" -> TeamDelete -> output final summary with artifact paths |
| Keep Active | Update session status="paused" -> output: "Resume with: Skill(skill='team-coordinate-v2', args='resume')" |
| Export Results | AskUserQuestion(target path) -> copy artifacts to target -> Archive & Clean |

## Cadence Control

**Beat model**: Event-driven, each beat = coordinator wake -> process -> spawn -> STOP.

```
Beat Cycle (single beat)
======================================================================
  Event                   Coordinator              Workers
----------------------------------------------------------------------
  callback/resume --> +- handleCallback -+
                      |  mark completed   |
                      |  check pipeline   |
                      +- handleSpawnNext -+
                      |  find ready tasks |
                      |  spawn workers ---+--> [team-worker A] Phase 1-5
                      |  (parallel OK)  --+--> [team-worker B] Phase 1-5
                      +- STOP (idle) -----+         |
                                                     |
  callback <-----------------------------------------+
  (next beat)              SendMessage + TaskUpdate(completed)
======================================================================

  Fast-Advance (skips coordinator for simple linear successors)
======================================================================
  [Worker A] Phase 5 complete
    +- 1 ready task? simple successor? --> spawn team-worker B directly
    +- complex case? --> SendMessage to coordinator
======================================================================
```

**Pipelines are dynamic**: Unlike static pipeline definitions, team-coordinate pipelines are generated per-task from the dependency graph.

## Session Resume

Coordinator supports `resume` / `continue` for interrupted sessions:

1. Scan `.workflow/.team/TC-*/team-session.json` for active/paused sessions
2. Multiple matches -> AskUserQuestion for selection
3. Audit TaskList -> reconcile session state <-> task status
4. Reset in_progress -> pending (interrupted tasks)
5. Rebuild team and spawn needed workers only
6. Create missing tasks with correct blockedBy
7. Kick first executable task -> Phase 4 coordination loop

## Error Handling

| Scenario | Resolution |
|----------|------------|
| Unknown command | Error with available command list |
| Dynamic role-spec not found | Error, coordinator may need to regenerate |
| Command file not found | Fallback to inline execution |
| Discuss subagent fails | Worker proceeds without discuss, logs warning |
| Explore cache corrupt | Clear cache, re-explore |
| Fast-advance spawns wrong task | Coordinator reconciles on next callback |
| capability_gap reported | Coordinator generates new role-spec via handleAdapt |
| Completion action fails | Default to Keep Active, log warning |
