find-coverage-gaps SKILL.md skillA
find-coverage-gaps from tomzx/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tomzx/agents/find-coverage-gaps@git:20261007.b35fc4bPins git:20261007.b35fc4b in mdr.lock. Pin the fingerprint instead.

Identify files and modules with missing or insufficient test coverage, ranked by churn and complexity, and suggest what to test first.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
TODAY=!`date +%Y-%m-%d` # Coverage Gaps Finds the parts of the codebase with the least test coverage, then ranks them by churn and complexity so the most important gaps appear first. Low coverage in a stable file is a minor concern. Low coverage in a file that changes constantly and is hard to understand is a production risk. ## Prerequisites - Working directory is the root of the repository - Optional: `$1` — path to limit the scan (defaults to `.`) - Tests must be runnable; coverage data is generated by running the test suite - Language-specific tools: - Python: `pytest-cov` (`uv add --dev pytest-cov`) - JavaScript/TypeScript: `jest --coverage` or `vitest --coverage` - Go: `go test -cover ./...` - Rust: `cargo tarpaulin` (`cargo install cargo-tarpaulin`) ## Coverage Thresholds | Coverage | Status | |----------|--------| | ≥ 80% | Acceptable | | 50–79% | 🟡 Gap — schedule tests | | < 50% | 🔴 Critical gap — prioritize | | 0% | 🔴 No tests at all | Files below threshold are ranked by a **risk score**: `(1 - coverage) × churn_commits × complexity_score`. ## Steps ### 1. Run the Test Suite with Coverage **Python:** ``` …

How to install
mdr add tomzx/agents/find-coverage-gaps@sha256:25a7b131fc989fafThe line at the top of this page pins the label git:20261007.b35fc4b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
