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

Pre-load (coordinator, before dispatch)

Codebase docs: If .workflow/codebase/ARCHITECTURE.md exists, read for module boundaries
Specs (arch): maestro load --type spec --category arch — load arch constraints as shared context
Specs (coding): maestro load --type spec --category coding — load coding constraints as shared context
Wiki knowledge: maestro search "architecture optimization refactor" --json — top 5 entries as prior context
All optional — proceed without if unavailable

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

Shared Constants

Session prefix: TAO
Session path: {run_dir}/work/team/
CLI tools: maestro delegate --mode analysis (read-only), maestro delegate --mode write (modifications)
Message bus: mcp__maestro__team_msg(session_id=<run-id>, ...)

Worker Spawn Template

Coordinator spawns workers using this template:

Agent({
  subagent_type: "team-worker",
  description: "Spawn <role> worker",
  team_name: "arch-opt",
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: {run_dir}/work/team
session_id: <run-id>
team_name: arch-opt
requirement: <task-description>
inner_loop: <true|false>

## Progress Milestones
session_id: <run-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final SendMessage.

Read role_spec file (@<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery) -> role Phase 2-4 -> built-in Phase 5 (report).`
})

Inner Loop roles (refactorer): Set inner_loop dynamically — true for single mode, false for fan-out/independent (parallel branches). Single-task roles (analyzer, designer, validator, reviewer): Set inner_loop: false.

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
