test-coverage-retrofit

What problem does it solve?

This Skill systematically retrofits unit tests to existing codebases using coverage-driven parallel test writing, enabling teams to raise test quality and achieve high coverage with guided, scalable steps.

Core Features & Use Cases

• Pattern discovery and planning: identifies test opportunities, architectural conventions, and integration points to focus retrofit efforts.
• Two-phase test generation: plan and write unit tests first, then integrate tests if needed, with automatic early stopping at target coverage.
• Haiku-guided test writing: uses lightweight, architecture-aware prompts to generate clear, maintainable tests aligned with project standards.
• Self-cleaning tests and isolation: encourages dynamic test data and cleanup patterns to prevent pollution and flakiness.
• Tracking and governance: generates a progress tracker and documentation to monitor coverage improvements over time.

Quick Start

Run the skill in your project root to generate a test retrofit plan and begin writing tests.
