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.

Does this coverage analysis tool work with both Python and TypeScript codebases?▼

Yes, this coverage analysis tool works with both Python and TypeScript codebases by leveraging standard coverage tools like pytest-cov for Python and istanbul or c8 for TypeScript and JavaScript environments.

What is the best way to find out which files need more tests when coverage drops below 80%?▼

The best way to find files needing more tests when coverage drops below 80% is to run an automated coverage analysis that highlights exactly which files and lines lack sufficient test coverage.

Can I get specific test recommendations for each identified code coverage gap?▼

Yes, you can get specific test recommendations for each identified code coverage gap, as the analysis provides actionable recommendations suggesting exactly which tests to write to improve code quality.
