Team UX Improve

Systematic UX improvement pipeline: scan -> diagnose -> design -> implement -> test. 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 | — | — | | scanner | roles/scanner/role.md | SCAN-* | false | | diagnoser | roles/diagnoser/role.md | DIAG-* | false | | designer | roles/designer/role.md | DESIGN-* | false | | implementer | roles/implementer/role.md | IMPL-* | true | | tester | roles/tester/role.md | TEST-* | false |

Utility Member Registry

Coordinator-only: Utility members can only be spawned by Coordinator. Workers CANNOT call spawn_agent() to spawn utility members.

| Utility Member | Path | Callable By | Purpose | |----------------|------|-------------|---------| | explorer | roles/explorer/role.md | Coordinator only | Explore codebase for UI component patterns and framework-specific patterns |

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, assign_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: ux-improve
Session path: .workflow/.team/ux-improve-<timestamp>/
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 test iterations: 5

Worker Spawn Template

Coordinator spawns workers using this template:

spawn_agent({
  agent_type: "team_worker",
  task_name: "<task-id>",
  fork_context: false,
  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({ targets: [...], timeout_ms: 900000 }) to collect results, then close_agent({ target }) each worker.

Model Selection Guide

UX improvement has an explorer utility member and a scan-diagnose-design-implement-test pipeline.

| Role | reasoning_effort | Rationale | |------|-------------------|-----------| | explorer | low | File reading and pattern summarization only (utility member) | | scanner | medium | Broad UI/UX issue scanning, pattern-based detection | | diagnoser | high | Root cause diagnosis of UX issues requires deep analysis | | designer | high | UX improvement design needs careful user experience reasoning | | implementer | high | UI code changes must preserve existing behavior | | tester | medium | Test execution follows defined UX verification criteria |

User Commands

| Command | Action | |---------|--------| | check / status | View execution status graph | | resume / continue | Advance to next step |

v4 Agent Coordination

Message Semantics

| Intent | API | Example | |--------|-----|---------| | Queue supplementary info (don't interrupt) | send_message | Send explorer findings to running scanner | | Assign implementation from design | assign_task | Assign IMPL task from designer output | | 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: "SCAN-001", items: [...] }) -- send explorer findings to scanner
assign_task({ target: "IMPL-001", items: [...] }) -- assign UX fix from designer output
close_agent({ target: "TEST-001" }) -- cleanup after UX testing

Explorer-Assisted Scanning

Coordinator spawns explorer (utility member) early to gather codebase context, then sends findings to scanner via upstream context:

// Explorer results inform scanner's scope
send_message({
  target: "SCAN-001",
  items: [
    { type: "text", text: `## Explorer Findings
component_patterns: <explorer's component inventory>
framework: <detected framework>
ui_library: <detected UI library>` }
  ]
})

Error Handling

| Scenario | Resolution | |----------|------------| | Unknown command | Error with available command list | | Role not found | Error with role registry | | Project path invalid | Re-prompt user for valid path | | Framework detection fails | request_user_input for framework selection | | Session corruption | Attempt recovery, fallback to manual | | Fast-advance conflict | Coordinator reconciles on next callback | | No UI issues found | Complete with empty fix list, generate clean bill report | | Test iterations exceeded | Accept current state, continue to completion |
