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 with Monocart Coverage Reports 3.x

## Scope and environment — check first

- This skill supports **MCR 3.x only**, with **Node.js >= 22.15.0** and the native ESM API. It does not provide workflows for other major versions. If the host uses another major version, stop applying these recipes and consult that version's documentation. Do not upgrade dependencies or the runtime without approval; for an approved upgrade, consult the package's `migrate-to-3.md`.
- Follow the user's language for replies and report labels. Reuse the host package manager, lockfile, test runner, build tools, and module conventions. MCR generates reports; it does not instrument Istanbul code automatically or require the entire host application to become ESM.
- From the **host project root**, locate the installed package and skill:

```sh
node -p "require.resolve('monocart-coverage-reports/package.json')"
node -p "require.resolve('monocart-coverage-reports/skills/monocart-coverage-reports/SKILL.md')"
```

How to install

The exact contents, by fingerprint

mdr add cenfun/monocart-coverage-reports/monocart-coverage-reports@sha256:ca1aa6085375a119

The line at the top of this page pins the label git:20261021.9fb7c6a, 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.
