Use the open-source free `Stryker.NET` mutation testing tool for .NET. Use when a repo needs to measure whether tests actually catch faults, especially in critical libraries or domains.

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

# Stryker.NET

## Trigger On

- the repo uses or wants `Stryker.NET`
- mutation testing is needed for high-risk code

## Value

- produce a concrete project delta: code, docs, config, tests, CI, or review artifact
- reduce ambiguity through explicit planning, verification, and final validation skills
- leave reusable project context so future tasks are faster and safer

## Do Not Use For

- every PR path by default in a large repo
- simple coverage collection

## Inputs

- the nearest `AGENTS.md`
- target projects and critical paths
- time budget for mutation runs

## Quick Start

1. Read the nearest `AGENTS.md` and confirm scope and constraints.
2. Run this skill's `Workflow` through the `Ralph Loop` until outcomes are acceptable.
3. Return the `Required Result Format` with concrete artifacts and verification evidence.

## Workflow

1. Run mutation testing on critical projects, not blindly on the whole mono-repo.
2. Keep it out of the fastest PR path unless the repo explicitly accepts the runtime cost.
3. Stabilize tests first; mutation testing amplifies flaky or slow suites.

## Bootstrap When Missing

If `Stryker.NET` is not configured yet:

1. Detect current state:

How to install

The exact contents, by fingerprint

mdr add postpartum-genushyacinthus29/dotnet-skills/dotnet-stryker@sha256:5d758afb62845c8f

The line at the top of this page pins the label v1.0.0, 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.
