Team IterDev

Iterative development team skill. Generator-Critic loops (developer<->reviewer, max 3 rounds), task ledger (task-ledger.json) for real-time progress, shared memory (cross-sprint learning), and dynamic pipeline selection for incremental delivery.

Role Registry

Role	Path	Prefix	Inner Loop
coordinator	roles/coordinator/role.md	—	—
architect	roles/architect/role.md	DESIGN-*	false
developer	roles/developer/role.md	DEV-*	true
tester	roles/tester/role.md	VERIFY-*	false
reviewer	roles/reviewer/role.md	REVIEW-*	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

Shared Constants

• Session prefix: IDS
• Session path: .workflow/.team/IDS-<slug>-<date>/
• 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:

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

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).`
})

Error Handling

Scenario	Resolution
Unknown command	Error with available command list
Role not found	Error with role registry
GC loop exceeds 3 rounds	Accept with warning, record in shared memory
Sprint velocity drops below 50%	Coordinator alerts user, suggests scope reduction
Task ledger corrupted	Rebuild from TaskList state
Conflict detected	Update conflict_info, notify coordinator, create DEV-fix task
Pipeline deadlock	Check blockedBy chain, report blocking point
