SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill automatically analyzes your project's test coverage, identifies specific areas lacking tests, and provides actionable recommendations to improve code quality and reduce bugs.

Core Features & Use Cases

  • Automated Coverage Analysis: Runs standard coverage tools (pytest-cov, istanbul/c8) to get precise coverage metrics.
  • Gap Identification: Pinpoints uncovered lines, branches, and functions.
  • Spec Mapping: Optionally maps coverage against your acceptance criteria to ensure requirements are tested.
  • Actionable Recommendations: Suggests specific tests to write for each identified gap.
  • Use Case: After writing new code, run this Skill to ensure all new logic is covered by tests. If coverage drops below 80%, it will highlight exactly which files and lines need more tests.

Quick Start

Analyze the test coverage for the current project and report any gaps.
