# team-frontend-debug — team-frontend-debug orchestrates a multi-role team for frontend quality assurance, routing feature lists to a testing pipeline or bug reports to a debugging pipeline. Both flows leverage Chrome DevTools MCP for browser inspection, DOM analysis, console monitoring, and performance tracing. The coordinator role parses your input, spawns specialized workers (tester, reproducer, analyzer, fixer, verifier), and manages progress across phases.

# Frontend Debug Team

Dual-mode frontend debugging: feature-list testing or bug-report debugging, powered by Chrome DevTools MCP.

## Pipeline Modes

| Input | Pipeline | Flow |
|-------|----------|------|
| Feature list / 功能清单 | `test-pipeline` | TEST → ANALYZE → FIX → VERIFY |
| Bug report / 错误描述 | `debug-pipeline` | REPRODUCE → ANALYZE → FIX → VERIFY |

## Role Registry

| Role | Path | Prefix | Inner Loop |
|------|------|--------|------------|
| coordinator | [roles/coordinator/role.md](roles/coordinator/role.md) | — | — |
| tester | [roles/tester/role.md](roles/tester/role.md) | TEST-* | true |
| reproducer | [roles/reproducer/role.md](roles/reproducer/role.md) | REPRODUCE-* | false |
| analyzer | [roles/analyzer/role.md](roles/analyzer/role.md) | ANALYZE-* | false |
| fixer | [roles/fixer/role.md](roles/fixer/role.md) | FIX-* | true |
| verifier | [roles/verifier/role.md](roles/verifier/role.md) | VERIFY-* | 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

## Shared Constants

- **Session prefix**: `TFD`
- **Session path**: `.workflow/.team/TFD-<slug>-<date>/`
- **CLI tools**: `ccw cli --mode analysis` (read-only), `ccw cli --mode write` (modifications)
- **Message bus**: `mcp__ccw-tools__team_msg(session_id=<session-id>, ...)`

## Workspace Resolution

Coordinator MUST resolve paths at Phase 2 before TeamCreate:

1. Run `Bash({ command: "pwd" })` → capture `project_root` (absolute path)
2. `skill_root = <project_root>/.claude/skills/team-frontend-debug`
3. Store in `team-session.json`:
   ```json
   { "project_root": "/abs/path/to/project", "skill_root": "/abs/path/to/skill" }
   ```
4. All worker `role_spec` values MUST use `<skill_root>/roles/<role>/role.md` (absolute)

This ensures workers spawned with `run_in_background: true` always receive an absolute, resolvable path regardless of their working directory.

## Chrome DevTools MCP Tools

All browser inspection operations use Chrome DevTools MCP. Reproducer and Verifier are primary consumers.

| Tool | Purpose |
|------|---------|
| `mcp__chrome-devtools__navigate_page` | Navigate to target URL |
| `mcp__chrome-devtools__take_screenshot` | Capture visual state |
| `mcp__chrome-devtools__take_snapshot` | Capture DOM/a11y tree |
| `mcp__chrome-devtools__list_console_messages` | Read console logs |
| `mcp__chrome-devtools__get_console_message` | Get specific console message |
| `mcp__chrome-devtools__list_network_requests` | Monitor network activity |
| `mcp__chrome-devtools__get_network_request` | Inspect request/response detail |
| `mcp__chrome-devtools__performance_start_trace` | Start performance recording |
| `mcp__chrome-devtools__performance_stop_trace` | Stop and analyze trace |
| `mcp__chrome-devtools__click` | Simulate user click |
| `mcp__chrome-devtools__fill` | Fill form inputs |
| `mcp__chrome-devtools__hover` | Hover over elements |
| `mcp__chrome-devtools__evaluate_script` | Execute JavaScript in page |
| `mcp__chrome-devtools__wait_for` | Wait for element/text |
| `mcp__chrome-devtools__list_pages` | List open browser tabs |
| `mcp__chrome-devtools__select_page` | Switch active tab |

## Worker Spawn Template

Coordinator spawns workers using this template:

```
Agent({
  subagent_type: "team-worker",
  description: "Spawn <role> worker",
  team_name: <team-name>,
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: <session-folder>
session_id: <session-id>
team_name: <team-name>
requirement: <task-description>
inner_loop: <true|false>

## Progress Milestones
session_id: <session-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final SendMessage.

Read role_spec file (@<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery) -> role Phase 2-4 -> built-in Phase 5 (report).`
})
```

## User Commands

| Command | Action |
|---------|--------|
| `check` / `status` | View execution status graph |
| `resume` / `continue` | Advance to next step |
| `revise <TASK-ID> [feedback]` | Revise specific task |
| `feedback <text>` | Inject feedback for revision |
| `retry <TASK-ID>` | Re-run a failed task |

## Completion Action

When pipeline completes, coordinator presents:

```
AskUserQuestion({
  questions: [{
    question: "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 debugging" },
      { label: "Export Results", description: "Export debug report and patches" }
    ]
  }]
})
```

## Session Directory

```
.workflow/.team/TFD-<slug>-<date>/
├── team-session.json           # Session state + role registry
├── evidence/                   # Screenshots, snapshots, network logs

```

## Error Handling

| Scenario | Resolution |
|----------|------------|
| All features pass test | Report success, pipeline completes without ANALYZE/FIX/VERIFY |
| Bug not reproducible | Reproducer reports failure, coordinator asks user for more details |
| Browser not available | Report error, suggest manual reproduction steps |
| Analysis inconclusive | Analyzer requests more evidence via iteration loop |
| Fix introduces regression | Verifier reports fail, coordinator dispatches re-fix |
| No issues found in test | Skip downstream tasks, report all-pass |
| Unknown command | Error with available command list |
| Role not found | Error with role registry |
