What problem does it solve?
This Skill helps teams turn roadmap requirements into executable tests before or after implementation, so acceptance criteria are verified at the right layer without guessing what to cover.
Core Features & Use Cases
- RED and GREEN TDD modes: Supports writing tests before implementation to prove they fail, then rerunning the same tests after coding to confirm they pass.
- Layered test coverage: Creates unit, component, integration, accessibility, and end-to-end tests based on what the task changes.
- Project-specific safety rules: Follows repository conventions for reading roadmap tasks, avoiding implementation reads in RED mode, using real databases for integration tests, and updating roadmap checkboxes.
- Typical use case: Use it when a backlog item changes a function, UI component, API route, or full user flow and you need the right tests written in the correct place.
Quick Start
Ask the test-writer skill to write RED or GREEN tests for the active roadmap task in docs/ROADMAP.md and follow the repository’s testing, accessibility, and roadmap-update rules.
