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	—	—
tester	roles/tester/role.md	TEST-*	true
reproducer	roles/reproducer/role.md	REPRODUCE-*	false
analyzer	roles/analyzer/role.md	ANALYZE-*	false
fixer	roles/fixer/role.md	FIX-*	true
verifier	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

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_input	ALLOWED	Orchestration
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: 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 spawning workers:

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:

   { "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 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:

spawn_agent({
  agent_type: "team_worker",
  items: [
    { type: "text", text: `## 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.` },

    { type: "text", text: `## Task Context
task_id: <task-id>
title: <task-title>
description: <task-description>
pipeline_phase: <pipeline-phase>` },

    { type: "text", text: `## Upstream Context
<prev_context>` }
  ]
})

After spawning, use wait_agent({ ids: [...], timeout_ms: 900000 }) to collect results, then close_agent({ id }) each worker.

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:

request_user_input({
  questions: [{
    question: "Pipeline complete. What would you like to do?",
    header: "Completion",
    multiSelect: false,
    options: [
      { label: "Archive & Clean (Recommended)", description: "Archive session, clean up" },
      { label: "Keep Active", description: "Keep session for follow-up debugging" },
      { label: "Export Results", description: "Export debug report and patches" }
    ]
  }]
})

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
