# Team Brainstorm

Orchestrate multi-agent brainstorming: generate ideas -> challenge assumptions -> synthesize -> evaluate. Supports Quick, Deep, and Full pipelines with Generator-Critic loop.

## Architecture

```

## Role Registry

| Role | Path | Prefix | Inner Loop |
|------|------|--------|------------|
| coordinator | [roles/coordinator/role.md](roles/coordinator/role.md) | — | — |
| ideator | [roles/ideator/role.md](roles/ideator/role.md) | IDEA-* | false |
| challenger | [roles/challenger/role.md](roles/challenger/role.md) | CHALLENGE-* | false |
| synthesizer | [roles/synthesizer/role.md](roles/synthesizer/role.md) | SYNTH-* | false |
| evaluator | [roles/evaluator/role.md](roles/evaluator/role.md) | EVAL-* | false |

## Role Router

Parse `$ARGUMENTS`:
- Has `--role <name>` -> Read `roles/<name>/role.md`, execute Phase 2-4
- No `--role` -> `roles/coordinator/role.md`, execute entry router

## Shared Constants

- **Session prefix**: `BRS`
- **Session path**: `.workflow/.team/BRS-<slug>-<date>/`
- **CLI tools**: `ccw cli --mode analysis` (read-only), `ccw cli --mode write` (modifications)
- **Message bus**: `mcp__ccw-tools__team_msg(session_id=<session-id>, ...)`

## Worker Spawn Template

Coordinator spawns workers using this template:

```
spawn_agent({
  agent_type: "team_worker",
  items: [
    { type: "text", text: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: <session-folder>
session_id: <session-id>
requirement: <topic-description>
inner_loop: false

Read role_spec file (<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.` },

    { type: "text", text: `## Task Context
task_id: <task-id>
title: <task-title>
description: <topic-description>
pipeline_phase: <pipeline-phase>` },

    { type: "text", text: `## Upstream Context
<prev_context>` }
  ]
})
```

After spawning, use `wait_agent({ ids: [...], timeout_ms: 900000 })` to collect results, then `close_agent({ id })` each worker.

**Parallel ideator spawn** (Full pipeline with N angles):

When Full pipeline has N parallel IDEA tasks, spawn N distinct team-worker agents named `ideator-1`, `ideator-2`, etc.

```
spawn_agent({
  agent_type: "team_worker",
  items: [
    { type: "text", text: `## Role Assignment
role: ideator
role_spec: <skill_root>/roles/ideator/role.md
session: <session-folder>
session_id: <session-id>
requirement: <topic-description>
agent_name: ideator-<N>
inner_loop: false

Read role_spec file (<skill_root>/roles/ideator/role.md) to load Phase 2-4 domain instructions.` },

    { type: "text", text: `## Task Context
task_id: <task-id>
title: <task-title>
description: <topic-description>
pipeline_phase: <pipeline-phase>` },

    { type: "text", text: `## Upstream Context
<prev_context>` }
  ]
})
```

After spawning, use `wait_agent({ ids: [...], timeout_ms: 900000 })` to collect results, then `close_agent({ id })` each worker.

## Error Handling

| Scenario | Resolution |
|----------|------------|
| Unknown command | Error with available command list |
| Role not found | Error with role registry |
| CLI tool fails | Worker fallback to direct implementation |
| Fast-advance conflict | Coordinator reconciles on next callback |
| Completion action fails | Default to Keep Active |
| Generator-Critic loop exceeds 2 rounds | Force convergence to synthesizer |
| No ideas generated | Coordinator prompts with seed questions |
