Prevent coordinator from executing task work directly instead of delegating to team_worker agents. Three-layer enforcement: - SKILL.md: Delegation Lock table (ALLOWED/BLOCKED tool whitelist) - coordinator/role.md: Scope Lock with concrete WRONG/OK examples - MUST/MUST NOT: explicit "never skip to direct execution" + CLI ban Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

| team-brainstorm | Unified team skill for brainstorming team. Uses team-worker agent architecture with role directories for domain logic. Coordinator orchestrates pipeline, workers are team-worker agents. Triggers on "team brainstorm". | spawn_agent(*), wait_agent(*), send_input(*), close_agent(*), report_agent_job_result(*), request_user_input(*), Read(*), Write(*), Edit(*), Bash(*), Glob(*), Grep(*) |
Team Brainstorm
Orchestrate multi-agent brainstorming: generate ideas -> challenge assumptions -> synthesize -> evaluate. Supports Quick, Deep, and Full pipelines with Generator-Critic loop.

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_input |
ALLOWED | Orchestration |
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.

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 |
