Automates code coverage analysis and provides AI-driven reviews of coverage gaps to improve test quality.
Coverage Review is a specialized skill for Claude Code designed to automate the testing feedback loop. It executes your project's local coverage tools, parses standard report formats like Cobertura, LCOV, or Clover, and identifies critical gaps in your test suite. By analyzing the source code of uncovered lines, it classifies risks—such as missing error handling or security logic—and provides actionable suggestions for new test cases. Whether you are performing a quick diff-based check on a PR or a full baseline assessment, this skill generates comprehensive Markdown reports to help maintain high code quality standards.
