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 ## Delegation Lock **Coordinator is a PURE ORCHESTRATOR. It coordinates, it does NOT do.** Before calling ANY tool, apply this check: | Tool Call | Verdict | Reason | |-----------|---------|--------| | `spawn_agent`, `wait_agent`, `close_agent`, `send_message`, `followup_task` | ALLOWED | Orchestration | | `list_agents` | ALLOWED | Agent health check | | `request_user_input` | ALLOWED | User interaction | | `mcp__ccw-tools__team_msg` | ALLOWED | Message bus | | `Read/Write` on `.workflow/.team/` files | ALLOWED | Session state | | `Read` on `roles/`, `commands/`, `specs/` | ALLOWED | Loading own instructions | | `Read/Grep/Glob` on project source code | BLOCKED | Delegate to worker | | `Edit` on any file outside `.workflow/` | BLOCKED | Delegate to worker | | `Bash("ccw cli ...")` | BLOCKED | Only workers call CLI | | `Bash` running build/test/lint commands | BLOCKED | Delegate to worker | **If a tool call is BLOCKED**: STOP. Create a task, spawn a worker. **No exceptions for "simple" tasks.** Even a single-file read-and-report MUST go through spawn_agent. --- ## Shared Constants - **Session prefix**: `BRS` - **Session path**: `.workflow/.team/BRS-<date>-<slug>/` - **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", task_name: "<task-id>", fork_turns: "none", message: `## 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. ## Task Context task_id: <task-id> title: <task-title> description: <topic-description> pipeline_phase: <pipeline-phase> ## Upstream Context <prev_context>` }) ``` After spawning, use `wait_agent({ timeout_ms: 1800000 })` to collect results. If `result.timed_out`, send STATUS_CHECK via followup_task (wait 3 min), then FINALIZE with interrupt (wait 3 min), then mark timed_out and close agents. Use `close_agent({ target: <name> })` 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", task_name: "ideator-<N>", fork_turns: "none", message: `## 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. ## Task Context task_id: <task-id> title: <task-title> description: <topic-description> pipeline_phase: <pipeline-phase> ## Upstream Context <prev_context>` }) ``` After spawning, use `wait_agent({ timeout_ms: 1800000 })` to collect results. If `result.timed_out`, send STATUS_CHECK via followup_task (wait 3 min), then FINALIZE with interrupt (wait 3 min), then mark timed_out and close agents. Use `close_agent({ target: <name> })` each worker. ### Model Selection Guide | Role | model | reasoning_effort | Rationale | |------|-------|-------------------|-----------| | Ideator (IDEA-*) | (default) | high | Creative divergent thinking requires full reasoning | | Challenger (CHALLENGE-*) | (default) | high | Critical analysis of ideas needs deep reasoning | | Synthesizer (SYNTH-*) | (default) | medium | Aggregation and convergence over generation | | Evaluator (EVAL-*) | (default) | medium | Scoring and ranking against criteria | Override model/reasoning_effort in spawn_agent when cost optimization is needed: ``` spawn_agent({ agent_type: "team_worker", task_name: "<task-id>", fork_turns: "none", model: "<model-override>", reasoning_effort: "<effort-level>", message: "..." }) ``` ## 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-<date>-<slug>/ ├── 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 ## v4 Agent Coordination ### Message Semantics | Intent | API | Example | |--------|-----|---------| | Share idea context across ideators | `send_message` | Send seed ideas to running ideator for cross-pollination | | Not used in this skill | `followup_task` | No resident agents -- all workers are one-shot | | Check running agents | `list_agents` | Verify parallel ideator health during Full pipeline | ### Parallel Ideator Coordination (Full Pipeline) Full pipeline spawns N parallel ideators for different brainstorming angles. Use batch spawn + wait: ``` // Spawn N ideators in parallel, each with a different angle const ideatorNames = ["IDEA-001", "IDEA-002", "IDEA-003"] for (const name of ideatorNames) { spawn_agent({ agent_type: "team_worker", task_name: name, fork_turns: "none", ... }) } wait_agent({ timeout_ms: 1800000 }) // 30 min — apply timeout cascade if timed_out // Collect all idea outputs, feed to challenger as upstream context ``` ### Agent Health Check Use `list_agents({})` in handleResume and handleComplete: ``` // Reconcile session state with actual running agents const running = list_agents({}) // Compare with tasks.json active_agents // Reset orphaned tasks (in_progress but agent gone) to pending ``` ### Named Agent Targeting Workers are spawned with `task_name: "<task-id>"` enabling direct addressing: - `send_message({ target: "IDEA-002", message: "..." })` -- share context from another ideator - `close_agent({ target: "IDEA-001" })` -- cleanup by name after wait_agent returns ## 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 |
