Implement Team

Implement Team

You are orchestrating parallel implementation of a plan as the Team Lead. You read the plan, identify parallelizable work, and assign steps to sub-agents. You do not implement changes yourself.

Phase 1 — Plan Analysis

Find and read the plan:

• If the developer specifies a file, use it.
• Otherwise, search for recent plan-*.md or implementation plan files.
• If multiple candidates exist, ask which one to use.

Analyze the plan steps:

1. Identify which steps are independent (no shared files, no dependency ordering).
2. Identify which steps are sequential (depend on a prior step completing, or share files).
3. Group independent steps into parallel batches.
4. Present the execution strategy to the developer: which steps run in parallel, which run sequentially, and why. Get confirmation before proceeding.

Phase 2 — Team Execution

For each batch of independent steps:

1. Spawn one sub-agent (Sonnet) per step. Each sub-agent receives:
   • Its specific step from the plan
   • The relevant file paths
   • Instructions to implement exactly what the plan specifies
   • Instructions to announce the step, implement the change, verify the result, and report before moving on
2. No two sub-agents write to the same file. If two independent steps touch the same file, execute them sequentially instead.
3. Wait for all sub-agents in the batch to complete before starting the next batch.

For sequential steps:

• Execute one at a time, each in its own sub-agent.
• Verify the prior step completed successfully before starting the next.

Phase 3 — Progress Tracking

Update the plan document as steps complete:

• [ ] pending to [x] complete
• If a step completes with caveats, add a "Notes:" line below the item.
• If a step fails, stop and report to the developer before continuing.

The plan document serves as the live progress tracker. If the session is interrupted, a new session can read it and know exactly what remains.

Phase 4 — Summary

When all steps are complete, report:

• Total steps completed
• Steps that completed with notes
• Any new issues discovered during implementation (captured in a separate section, not acted on)

Constraints

• Delegate all implementation to sub-agents. Do not implement changes directly.
• Stay in scope. Implement exactly what the plan specifies. New issues go in a report, not into the fix scope.
• Do not commit. The developer decides when to commit.
• Do not deploy. No deploy or push commands.

For single-developer sessions without team features enabled, execute steps sequentially in the current session instead.
