Team Testing

Orchestrate multi-agent test pipeline: strategist -> generator -> executor -> analyst. Progressive layer coverage (L1/L2/L3) with Generator-Critic loops for coverage convergence.

Role Registry

Role	Path	Prefix	Inner Loop
coordinator	roles/coordinator/role.md	—	—
strategist	roles/strategist/role.md	STRATEGY-*	false
generator	roles/generator/role.md	TESTGEN-*	true
executor	roles/executor/role.md	TESTRUN-*	true
analyst	roles/analyst/role.md	TESTANA-*	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: TST
• Session path: .workflow/.team/TST-<date>-<slug>/
• Team name: testing
• 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: <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.

Model Selection Guide

Role	model	reasoning_effort	Rationale
Strategist (STRATEGY-*)	(default)	high	Test strategy requires deep code understanding
Generator (TESTGEN-*)	(default)	high	Test code generation needs precision
Executor (TESTRUN-*)	(default)	medium	Running tests and collecting results, less reasoning
Analyst (TESTANA-*)	(default)	high	Coverage analysis and quality assessment

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: "..."
})

v4 Agent Coordination

Message Semantics

Intent	API	Example
Send strategy to running generators	send_message	Queue test strategy findings to TESTGEN-* workers
Not used in this skill	followup_task	No resident agents -- all workers are one-shot
Check running agents	list_agents	Verify parallel generator/executor health

Parallel Test Generation

Comprehensive pipeline spawns multiple generators (per layer) and executors in parallel:

// Spawn parallel generators for L1 and L2
const genNames = ["TESTGEN-001", "TESTGEN-002"]
for (const name of genNames) {
  spawn_agent({ agent_type: "team_worker", task_name: name, ... })
}
wait_agent({ timeout_ms: 1800000 })  // 30 min — apply timeout cascade if timed_out

GC Loop Coordination

Generator-Critic loops create dynamic TESTGEN-fix and TESTRUN-fix tasks. The coordinator tracks gc_rounds[layer] and creates fix tasks dynamically when coverage is below target.

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: "TESTGEN-001", message: "..." }) -- queue strategy context to running generator
• close_agent({ target: "TESTRUN-001" }) -- cleanup by name after wait_agent returns

Completion Action

When pipeline completes, coordinator presents:

functions.request_user_input({
  questions: [{
    question: "Testing pipeline complete. What would you like to do?",
    header: "Completion",
    multiSelect: false,
    options: [
      { label: "Archive & Clean (Recommended)", description: "Archive session, clean up team" },
      { label: "Keep Active", description: "Keep session for follow-up work" },
      { label: "Deepen Coverage", description: "Add more test layers or increase coverage targets" }
    ]
  }]
})

Error Handling

Scenario	Resolution
Unknown --role value	Error with available role list
Role not found	Error with expected path (roles//role.md)
CLI tool fails	Worker fallback to direct implementation
GC loop exceeded	Accept current coverage with warning
Fast-advance conflict	Coordinator reconciles on next callback
Completion action fails	Default to Keep Active
