System Documentation

What problem does it solve?

This Skill helps engineering teams measure and improve test coverage, identify untested code paths and branches, and enforce coverage thresholds so regressions are caught before merging.

Core Features & Use Cases

  • Configure coverage providers and thresholds for Vitest or Jest, choosing c8 or Istanbul as the provider.
  • Generate human-readable HTML reports, machine-readable lcov/json outputs, and CI-ready summaries to find red (uncovered) and yellow (partially covered) lines.
  • Integrate with CI to fail builds below per-file or global thresholds and upload coverage artifacts to Codecov or Coveralls for trend tracking.
  • Prioritize tests for critical business logic, error paths, and branch coverage to raise overall reliability.

Quick Start

Run the test suite with coverage enabled, open the HTML report, and add tests for uncovered branches and critical files.
