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

# Mutineer

> Mutineer checks whether your Ruby tests would catch a bug. It makes one small
> code change at a time and runs your Minitest or RSpec tests. Each changed version
> is a mutant. A failing test kills it; passing tests let it survive. Review each
> survivor for a missing test or a change that leaves the behaviour unchanged.

Line coverage shows which lines ran. Mutation testing checks whether the tests
notice a change. Start with one file and understand the results before adding a CI gate.

Key facts:
- **Written from scratch**: no code from Mutant or any other mutation-testing tool. MIT for every use. How it differs from Mutant: [comparison guide](https://github.com/davidteren/mutineer/blob/main/docs/comparison.md#mutineer-and-mutant).
- **Zero runtime dependencies** — Prism + stdlib only. No `eval`. Test-framework changes stay in disposable child processes.
- **One mutation per mutant**, validity-checked by re-parsing; 21 mutation operators.
- **Fork-isolated, parallel** execution (Linux + macOS); coverage-guided per-line test selection.

How to install

The exact contents, by fingerprint
mdr add davidteren/mutineer/docs/llms.txt@sha256:c8c17b274bd9bc53

The line at the top of this page pins the label git:20261026.80198df, 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.
