# 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](roles/coordinator/role.md) | — | — |
| strategist | [roles/strategist/role.md](roles/strategist/role.md) | STRATEGY-* | false |
| generator | [roles/generator/role.md](roles/generator/role.md) | TESTGEN-* | true |
| executor | [roles/executor/role.md](roles/executor/role.md) | TESTRUN-* | true |
| analyst | [roles/analyst/role.md](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: "..."
})
```

## User Commands

| Command | Action |
|---------|--------|
| `check` / `status` | View pipeline status graph |
| `resume` / `continue` | Advance to next step |
| `revise <TASK-ID>` | Revise specific task |
| `feedback <text>` | Inject feedback for revision |

## 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/<name>/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 |
