Team UI Design

Systematic UI design pipeline: research -> design tokens -> review -> implementation. Built on team-worker agent architecture — all worker roles share a single agent definition with role-specific Phase 2-4 loaded from roles/<role>/role.md.

Role Registry

Role	Path	Prefix	Inner Loop
coordinator	roles/coordinator/role.md	—	—
researcher	roles/researcher/role.md	RESEARCH-*	false
designer	roles/designer/role.md	DESIGN-*	false
reviewer	roles/reviewer/role.md	AUDIT-*	false
implementer	roles/implementer/role.md	BUILD-*	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: UDS
• Session path: .workflow/.team/UDS-<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>, ...)
• Max GC rounds: 2

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: 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

UI design is a creative pipeline where research findings inform design decisions. Researcher needs thorough analysis, designer needs creative reasoning.

Role	reasoning_effort	Rationale
researcher	high	Deep analysis of existing design systems and patterns
designer	high	Creative design token/component spec generation
reviewer	high	Design audit must catch consistency and accessibility issues
implementer	medium	Implementation follows defined design specs

Research-to-Design Context Flow

Researcher findings must reach designer via coordinator's upstream context:

// After RESEARCH-001 completes, coordinator sends findings to designer
spawn_agent({
  agent_type: "team_worker",
  task_name: "DESIGN-001",
  fork_turns: "none",
  message: `## Upstream Context
Research findings: <session>/research/design-intelligence.json
Component inventory: <session>/research/component-inventory.json
Accessibility audit: <session>/research/accessibility-audit.json`
})

v4 Agent Coordination

Message Semantics

Intent	API	Example
Queue supplementary info (don't interrupt)	send_message	Send research findings to running designer
Assign build from reviewed specs	followup_task	Assign BUILD task after audit passes
Check running agents	list_agents	Verify agent health during resume

Agent Health Check

Use list_agents({}) in handleResume and handleComplete:

// Reconcile session state with actual running agents
const running = list_agents({})
// Compare with meta.json active tasks
// 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: "DESIGN-001", message: "..." }) -- send additional research findings to designer
• followup_task({ target: "BUILD-001", message: "..." }) -- assign implementation from reviewed design specs
• close_agent({ target: "AUDIT-001" }) -- cleanup after design audit

Error Handling

Scenario	Resolution
Unknown command	Error with available command list
Role not found	Error with role registry
Session corruption	Attempt recovery, fallback to manual
Fast-advance conflict	Coordinator reconciles on next callback
Completion action fails	Default to Keep Active
GC loop stuck > 2 rounds	Escalate to user: accept / retry / terminate
