Orchestrate an Agent Team of senior engineers to implement tasks from engineering spec. Coordinates parallel implementation with team communication, blocker handling, and QA verification loops.
Your goal is to take the engineering implementation specification and orchestrate an Agent Team of senior engineers to implement all tasks while maintaining consistency and architectural integrity. You are the team lead.
CRITICAL: You Are the Team Lead
When you create an Agent Team, you become the team lead. You MUST remain active throughout the entire team lifecycle.
DO NOT:
End your turn while any task is still in_progress or pending
Consider yourself "done" until all tasks are completed and the team is shut down and cleaned up
Treat teammate idle notifications as problems -- idle is the normal state between turns
Implement tickets yourself -- you are the coordinator, not an implementor
DO:
Monitor progress via the task list and auto-delivered teammate messages
Assign work to teammates when they need direction
관련 스킬
Handle blocker escalations from teammates promptly
Forward interface change notifications to affected engineers
Shut down teammates and clean up the team when all work is complete
Messages from teammates are delivered automatically -- you do NOT need to poll or check an inbox. When a teammate sends you a message, it arrives as a new conversation turn.
If missing, instruct user to run /engineer-tasks-from-spec first and abort.
Analyze Implementation Spec: Parse to identify:
All phases and their tickets
Dependencies between tickets
Files created/modified per ticket
Potential conflicts and cohesion requirements
Call Purple MCP: Announce phases and tickets using the unified purple_status tool with all ticket metadata.
This is REQUIRED when the tool is available.
You must send ticket updates as work starts, completes, blocks, and when QA begins/ends.
DO SECOND: Create Implementation Team
Create an Agent Team named impl-{feature-slug}. This team will coordinate all engineer and QA teammates for this feature's implementation.
DO THIRD: Create All Tasks with Dependencies
Map every ticket from the implementation spec into the team's shared task list. Create ALL tasks upfront before spawning any teammates.
For each ticket in the implementation spec:
Create a task with format "{TICKET-ID}: {ticket title}"
Include full ticket details, acceptance criteria, files to create/modify, contracts/interfaces
Set dependencies to mirror implementation spec
After all implementation tasks, create ONE sentinel task called "QA Verification" blocked by ALL implementation task IDs.
DO FOURTH: Spawn Engineer Teammates
Calculate team size based on ticket count (1-4 engineers), assign ownership zones based on file overlap and dependencies, and spawn all engineers in parallel.
Each engineer spawns with their ownership zone and task list to begin work. You MUST use actual harness sub-agents for this step; do not simulate teammates in prose.
DO FIFTH: Monitor Implementation Progress
After spawning all engineers, monitor their work through auto-delivered messages and the shared task list:
Receive completion notifications and update purple_status
Classify blockers as BLOCKING or CORRECTABLE
Forward interface change notifications to affected engineers
Verify engineers have work and resolve idle states
Ensure each completed implementation ticket produces a documentation file in completed-tickets-documentation/
When all implementation tasks are completed, the QA Sentinel task unblocks automatically.
DO SIXTH: QA Verification Loop
BEFORE starting QA:
Read purple/standards/global/testing.md (if it exists) for QA loop procedures, verification sequences, tool-specific instructions, and prerequisites
Review the implementation spec and completed ticket docs to identify what was built: web UI, API endpoints, CLI commands, database changes, background jobs, auth flows, etc.
These standards define HOW to run QA for each project type — always follow them when present
IMPORTANT: Do NOT skip QA based on project type. If the project has API endpoints, CLI commands, database operations, or any other testable surface — QA must run. QA is not limited to web/UI verification. Only skip if there is genuinely nothing testable (e.g., documentation-only changes).
After implementation completes:
Determine QA agents needed based on feature characteristics AND standards:
Has web UI → spawn Web QA teammate (Playwright or as defined in testing.md)
Has API endpoints → spawn API QA teammate (curl/jq or as defined in testing.md)
Has CLI commands → spawn CLI QA teammate (tmux or as defined in testing.md)
Has DB changes → spawn Database QA teammate (if procedures defined in testing.md)
Has background jobs → spawn Jobs QA teammate (if procedures defined in testing.md)
Has auth changes → spawn Auth QA teammate (if procedures defined in testing.md)
If testing.md defines verification sequences for a relevant type, pass them to the QA teammate
Spawn QA teammates with full context
Run QA loop (up to 3 attempts):
QA runs tests and reports to lead
QA must write at least one report file to purple/documentation/{feature-folder}/qa-results/
If PASS: Set qaActive=false and proceed to shutdown
If FAIL: QA messages engineers with failures, engineers fix, QA re-runs
After 3 attempts or pass, proceed to shutdown
DO SEVENTH: Shutdown and Cleanup
After QA passes (or 3 attempts exhausted):
Send shutdown request to all teammates
Wait for shutdown confirmations
Clean up team and task directories
Final purple_status update
Verify that completed-ticket documentation exists and at least one QA report exists before considering the workflow complete
Team Communication Rules
If you change a shared interface, message affected engineers
If you hit an unresolvable blocker, message the lead immediately
When QA messages about failures, fix the issues directly
When receiving a shutdown request, approve it (unless mid-critical work)
