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:
PERF-OPT - Session path:
.workflow/.team/PERF-OPT-<date>-<slug>/ - Team name:

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: <task-description>
inner_loop: <true|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: <task-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 }) each worker.
Inner Loop roles (optimizer): Set inner_loop: true.
Single-task roles (profiler, strategist, benchmarker, reviewer): Set inner_loop: false.
Model Selection Guide
Performance optimization is measurement-driven. Profiler and benchmarker need consistent context for before/after comparison.
| Role | reasoning_effort | Rationale |
|---|---|---|
| profiler | high | Must identify subtle bottlenecks from profiling data |
| strategist | high | Optimization strategy requires understanding tradeoffs |
| optimizer | high | Performance-critical code changes need precision |
| benchmarker | medium | Benchmark execution follows defined measurement plan |
| reviewer | high | Must verify optimizations don't introduce regressions |
Benchmark Context Sharing with fork_turns
For before/after comparison, benchmarker should share context with profiler's baseline:
spawn_agent({
agent_type: "team_worker",
task_name: "BENCH-001",
fork_turns: "all", // Share context so benchmarker sees profiler's baseline metrics
reasoning_effort: "medium",
message: "..."
})
User Commands

v4 Agent Coordination
Message Semantics
| Intent | API | Example |
|---|---|---|
| Queue supplementary info (don't interrupt) | send_message | Send baseline metrics to running optimizer |
| Assign fix after benchmark regression | followup_task | Assign FIX task when benchmark shows regression |
| Check running agents | list_agents | Verify agent health during resume |
Agent Health Check
Use list_agents({}) in handleResume and handleComplete:
// Reconcile session state with actual running agents
const running = list_agents({})
// Compare with session.json active tasks
// 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: "IMPL-001", message: "..." })-- send strategy details to optimizerfollowup_task({ target: "IMPL-001", message: "..." })-- assign fix after benchmark regressionclose_agent({ target: "BENCH-001" })-- cleanup after benchmarking completes
Baseline-to-Result Pipeline
Profiler baseline metrics flow through the pipeline and must reach benchmarker for comparison:
- PROFILE-001 produces
baseline-metrics.jsonin artifacts/ - Coordinator includes baseline reference in upstream context for all downstream workers
- BENCH-001 reads baseline and compares against post-optimization measurements
- If regression detected, coordinator auto-creates FIX task with regression details
Completion Action
When the pipeline completes:
functions.request_user_input({
questions: [{
question: "Team pipeline complete. What would you like to do?",
header: "Completion",
multiSelect: false,
options: [
{ label: "Archive & Clean (Recommended)", description: "Archive session, clean up tasks and team resources" },
{ label: "Keep Active", description: "Keep session active for follow-up work or inspection" },
{ label: "Export Results", description: "Export deliverables to a specified location, then clean" }
]
}]
})

Error Handling
| Scenario | Resolution |
|---|---|
| Unknown --role value | Error with role registry list |
| Role file not found | Error with expected path (roles/{name}/role.md) |
| Profiling tool not available | Fallback to static analysis methods |
| Benchmark regression detected | Auto-create FIX task with regression details |
| Review-fix cycle exceeds 3 iterations | Escalate to user |
| One branch IMPL fails | Mark that branch failed, other branches continue |
| Fast-advance conflict | Coordinator reconciles on next callback |
| Completion action fails | Default to Keep Active |
