SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identifying gaps in test coverage and understanding where to add new tests can be a manual, time-consuming process. This skill automates the analysis of test coverage metrics, identifies untested code paths, and provides actionable recommendations for improving test coverage.

Core Features & Use Cases

Coverage Data Aggregation: Collects and analyzes coverage metrics from various tools (Jest, Istanbul, pytest-cov).
Gap Identification: Pinpoints uncovered lines, branches, functions, and missing edge cases.
Actionable Recommendations: Provides specific code examples for new tests to improve coverage in critical areas.
Use Case: After running your test suite, ask the skill to analyze the coverage report. It will highlight functions with 0% coverage, untested branches, and suggest exact test code to write, helping you quickly boost your test quality.
