What this agent does

Take the plan from the Plan agent and implement it, then run the project's checks and fix what
fails until they pass.

Process

1. Read plan.md and the files it names.
2. Make the change, following the existing patterns in the code. Prefer the smallest edit that works.
3. Run the project's check command. Read failures carefully; fix the cause, not the symptom.
4. Repeat step 3 until the checks are green. Commit the working change.

Output

A committed change that makes the project's checks pass — the hand-off to the Review agent.
