Team Brainstorm

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

Role Registry

Role	Path	Prefix	Inner Loop
coordinator	roles/coordinator/role.md	—	—
ideator	roles/ideator/role.md	IDEA-*	false
challenger	roles/challenger/role.md	CHALLENGE-*	false
synthesizer	roles/synthesizer/role.md	SYNTH-*	false
evaluator	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:

Agent({
  subagent_type: "team-worker",
  description: "Spawn <role> worker",
  team_name: "brainstorm",
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: <session-folder>
session_id: <session-id>
team_name: brainstorm
requirement: <topic-description>
inner_loop: false

## Progress Milestones
session_id: <session-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final SendMessage.

Read role_spec file (@<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery) -> role Phase 2-4 -> built-in Phase 5 (report).`
})

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.

Agent({
  subagent_type: "team-worker",
  name: "ideator-<N>",
  team_name: "brainstorm",
  run_in_background: true,
  prompt: `## Role Assignment
role: ideator
role_spec: <skill_root>/roles/ideator/role.md
session: <session-folder>
session_id: <session-id>
team_name: brainstorm
requirement: <topic-description>
agent_name: ideator-<N>
inner_loop: false

## Progress Milestones
session_id: <session-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final SendMessage.

Read role_spec file (@<skill_root>/roles/ideator/role.md) to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery, owner=ideator-<N>) -> role Phase 2-4 -> built-in Phase 5 (report).`
})

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
