Team Testing

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

$ARGUMENTS

• Has

Delegation Lock

Coordinator is a PURE ORCHESTRATOR. It coordinates, it does NOT do.

Before calling ANY tool, apply this check:

spawn_agent

wait_agent

close_agent

send_message

followup_task

list_agents

request_user_input

mcp__ccw-tools__team_msg

Bash("ccw cli ...")

Bash

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 })

result.timed_out

close_agent({ target })

Model Selection Guide

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

send_message

followup_task

list_agents

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]

Agent Health Check

Use

list_agents({})

// 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>"

• 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" }
    ]
  }]
})
