team-brainstorm

# Team Brainstorm Orchestrate multi-agent brainstorming: generate ideas → challenge assumptions → synthesize → evaluate. Supports Quick, Deep, and Full pipelines with Generator-Critic loop. ## Architecture ``` Skill(skill="team-brainstorm", args="topic description") | SKILL.md (this file) = Router | +--------------+--------------+ | | no --role flag --role <name> | | Coordinator Worker roles/coordinator/role.md roles/<name>/role.md | +-- analyze → dispatch → spawn workers → STOP | +-------+-------+-------+ v v v v [ideator][challenger][synthesizer][evaluator] ``` ## 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: ``` 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).` }) ``` ## User Commands | Command | Action | |---------|--------| | `check` / `status` | View execution status graph, no advancement | | `resume` / `continue` | Check worker states, advance next step | ## Session Directory ``` .workflow/.team/BRS-<slug>-<date>/ ├── session.json # Session metadata + pipeline + gc_round ├── task-analysis.json # Coordinator analyze output ├── .msg/ │ ├── messages.jsonl # Message bus log │ └── meta.json # Session state + cross-role state ├── wisdom/ # Cross-task knowledge │ ├── learnings.md │ ├── decisions.md │ ├── conventions.md │ └── issues.md ├── ideas/ # Ideator output │ ├── idea-001.md │ └── idea-002.md ├── critiques/ # Challenger output │ ├── critique-001.md │ └── critique-002.md ├── synthesis/ # Synthesizer output │ └── synthesis-001.md └── evaluation/ # Evaluator output └── evaluation-001.md ``` ## Specs Reference - [specs/pipelines.md](specs/pipelines.md) — Pipeline definitions and task registry ## 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 |
