Activation requires either supplied .NET coverage reports/percentages/line, branch, or condition metrics, or an explicit request to collect .NET coverage for analysis. USE FOR: interpreting that evidence, including Cobertura data, partial conditions, plateaus, target arithmetic, project-wide coverage-backed CRAP, and coverage-backed refactoring safety. Analyze supplied reports directly without rerunning tests or installing tools. DO NOT USE FOR: requests with neither coverage evidence nor…

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

# Coverage Analysis

## Purpose

Explain what .NET coverage evidence proves, reconcile target arithmetic, and
identify the code blocking progress. Add complexity/CRAP ranking only when the
user explicitly asks for risk hotspots, CRAP, priorities by risk, or refactoring
safety.

## When to Use

Use this skill for interpreting supplied .NET line/branch/condition evidence,
coverage gaps and plateaus, target arithmetic, or explicit project-wide
coverage-backed risk analysis.

## When Not to Use

- **Named method, class, or file CRAP/refactoring-safety analysis** — use the `crap-score` skill instead
- **Static source-to-test pairing or listing files with no tests** — use `find-untested-sources`
- **Behavioral or pseudo-mutation gaps in existing tests** — use `test-gap-analysis`
- **Test trait/category distributions or coverage shape by test type** — use `test-tagging`
- **Writing or generating tests** — this skill identifies where tests are needed, not write them
- **General test execution** unrelated to coverage or CRAP analysis

How to install

The exact contents, by fingerprint
mdr add dotnet/skills/coverage-analysis@sha256:ce960ce57da39884

The line at the top of this page pins the label git:20261008.a51399b, 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.
