Judge whether tests catch realistic regressions and recommend what to keep, change, or remove. Use when the user asks whether tests are useful or well written, or when another skill needs a test-quality check.

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

# Test Quality Audit

A test is worth keeping when it fails on a realistic regression of a contract, meaning behavior that users or callers rely on. Judge every test by that standard. Coverage, test count, and whether the test was written first do not count. A small suite whose failures point at real defects is better than a large one, so do not ask for more tests by default.

Call a test weak only when the evidence shows it protects no contract or costs more to maintain than it protects. If missing context prevents that judgment, say so instead of assuming the test has little value.

## What to read

Start with the tests under review, then read only what you need to judge them:

- the implementation under test and its public or user-visible behavior
- important branches and failure paths
- fixtures, mocks, factories, snapshots, and helpers
- existing tests for the same behavior
- the PR intent, bug report, or known regression when available
- the commands, selection rules, and prerequisites that decide whether the tests run
- external boundaries: database, API, auth, queue, filesystem, time, randomness, network
…

How to install

The exact contents, by fingerprint

mdr add marcellocurto/skills/test-quality-audit@sha256:ce537746fc73af1e

The line at the top of this page pins the label git:20261029.444423a, 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.
