Can it show me specific lines of missing code?

Yes, the skill identifies and highlights specific lines or blocks of code that are not covered by any tests.

Does it require prior configuration?

Your project should have a coverage tool configured (like nyc in package.json) for the skill to successfully collect and parse data.

What tools does this skill support?

It integrates with popular coverage tools like nyc for Node.js, coverage.py for Python, and JaCoCo for Java.

How do I trigger the coverage analysis?

You can use natural language requests like 'analyze coverage' or 'code coverage report', or use the shortcut 'cov'.

Security & Testing

Analyzes code coverage metrics and identifies untested logic to ensure comprehensive software quality and test suite effectiveness.

The Test Coverage Analyzer skill empowers Claude to evaluate the effectiveness of your test suites by executing tests with coverage tracking and parsing the resulting data. It helps developers maintain high code quality standards by pinpointing specific lines or branches of code that lack coverage, generating detailed reports across statement, function, and branch metrics. By integrating with standard tools like nyc, coverage.py, and JaCoCo, this skill allows you to quickly identify gaps in your testing strategy and enforce coverage thresholds directly within your AI-assisted workflow.
