Team Architecture Optimization

Orchestrate multi-agent architecture optimization: analyze codebase -> design refactoring plan -> implement changes -> validate improvements -> review code quality.

Role Registry

Role	Path	Prefix	Inner Loop
coordinator	roles/coordinator/role.md	—	—
analyzer	roles/analyzer/role.md	ANALYZE-*	false
designer	roles/designer/role.md	DESIGN-*	false
refactorer	roles/refactorer/role.md	REFACTOR-, FIX-	true
validator	roles/validator/role.md	VALIDATE-*	false
reviewer	roles/reviewer/role.md	REVIEW-, QUALITY-	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: TAO
• Session path: .workflow/.team/TAO-<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 }) 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: <name> }) each worker.

Inner Loop roles (refactorer): Set inner_loop: true. Single-task roles (analyzer, designer, validator, reviewer): Set inner_loop: false.

Model Selection Guide

Architecture optimization is reasoning-intensive. All analysis and design roles need high reasoning effort.

Role	reasoning_effort	Rationale
analyzer	high	Deep structural analysis of codebase architecture
designer	high	Architecture redesign requires careful reasoning about tradeoffs
refactorer	high	Code transformations must preserve correctness
validator	high	Validation must thoroughly check refactoring correctness
reviewer	high	Code quality review demands deep understanding

Override in spawn_agent when needed:

spawn_agent({
  agent_type: "team_worker",
  task_name: "<task-id>",
  fork_turns: "none",
  reasoning_effort: "high",
  message: "..."
})

User Commands

v4 Agent Coordination

Message Semantics

Intent	API	Example
Queue supplementary info (don't interrupt)	send_message	Send codebase patterns to running analyzer
Assign new work / trigger processing	followup_task	Assign fix task to refactorer after review feedback
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 session.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: "ANALYZE-001", message: "..." }) -- queue analysis context without interrupting
• followup_task({ target: "REFACTOR-001", message: "..." }) -- assign fix task after review feedback
• close_agent({ target: "VALIDATE-001" }) -- cleanup by name

Merged Exploration Pattern

For architecture analysis, analyzer may need broad codebase exploration. Consider spawning analyzer with fork_turns: "all" when deep structural analysis of interconnected modules is needed:

spawn_agent({
  agent_type: "team_worker",
  task_name: "ANALYZE-001",
  fork_turns: "all",   // Share coordinator's codebase context
  reasoning_effort: "high",
  message: "..."
})

Error Handling

Scenario	Resolution
Unknown command	Error with available command list
Role not found	Error with role registry
CLI tool fails	Worker fallback to direct implementation
Fast-advance conflict	Coordinator reconciles on next callback
Completion action fails	Default to Keep Active
consensus_blocked HIGH	Coordinator creates revision task or pauses pipeline
Branch fix cycle >= 3	Escalate only that branch to user, others continue
max_branches exceeded	Coordinator truncates to top N at CP-2.5
