What problem does it solve?
Guides development from failing tests to clean, production-quality code changes that respect the repository’s ownership boundaries and style rules.
Core Features & Use Cases
- Test-driven production edits: Uses failing test signals to implement the smallest correct production change inside the task’s declared file ownership.
- Quality-guarded implementation: Enforces styleguide compliance, structured logging, safe error handling, and “no silent failures” behavior.
- Deterministic handoff workflow: Produces a commit message draft and hands off to the tester for validation without altering tests.
Quick Start
Use the builder skill to read the failing tests for your assigned task, implement the required changes only within the declared file ownership, then self-audit against the styleguide and reviewer checklist before handing off to the tester.
