What problem does it solve?
This Skill turns an approved implementation plan into tested, maintainable code while preventing scope creep, unverified changes, and broken handoffs.
Core Features & Use Cases
- Plan-Driven Implementation: Executes tasks in the prescribed order and tracks progress directly in the plan file.
- Test-Driven Development: Uses characterization tests, red-green-refactor cycles, incremental changes, and frequent verification.
- Quality and Safety Controls: Enforces build checks, explicit blocker handling, strict scope boundaries, and preservation of file history during moves or renames.
- Use Case: Give the Skill a feature plan and repository access so it can implement each step, add or update tests, verify the build, and mark completed work without committing changes.
Quick Start
Use the engineer skill with the path to an approved plan file to implement its steps, verify the tests, and update progress.
