Team Frontend Development

Unified team skill: frontend development with built-in ui-ux-pro-max design intelligence. Covers requirement analysis, design system generation, frontend implementation, and quality assurance. Built on team-worker agent architecture — all worker roles share a single agent definition with role-specific Phase 2-4 loaded from role.md specs.

$ARGUMENTS

• Has

  , execute Phase 2-4
• No

  --role

  , execute entry router

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:

  FE

• Session path:

  .workflow/.team/FE-<date>-<slug>/

• 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: "..."
})

Message Semantics

send_message

followup_task

list_agents

Pipeline Pattern

Sequential pipeline with GC loops: analyst -> architect -> developer -> QA. In system mode, architect revision (ARCH-002) and developer (DEV-001) may run in parallel after QA-001 arch review.

fork_turns Consideration

Developer workers (DEV-*) benefit from

fork_turns: "all"

// Consider fork_turns: "all" for developer in feature/system modes
spawn_agent({
  agent_type: "team_worker",
  task_name: "DEV-001",
  fork_turns: "all",  // Developer gets full coordinator context including design decisions
  message: "..."
})

GC Loop (QA Fix Cycle)

QA may flag FIX_REQUIRED, creating DEV-fix + QA-recheck tasks (max 2 rounds). If QA score remains < 6 after 2 rounds, escalate to user.

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: "DEV-001", message: "..." })

  -- queue architecture specs to running developer

• close_agent({ target: "ARCH-001" })

  -- cleanup by name after completion
