Mutation Test Generator

95 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

By PramodDutta/qaskills (GitHub) · coding · 246 stars · scanned at commit 8d6cf5f

Generate and run mutation tests to measure test suite effectiveness by introducing code mutations and verifying detection rates.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'mutation-test-generator' ] || [ -L ~/.agents/skills/'mutation-test-generator' ]; then echo 'A skill folder named mutation-test-generator already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/PramodDutta/qaskills' "$d" && git -C "$d" checkout --quiet '8d6cf5f6db54e56d14bd0ea2c9cfe7a097fb07ee' -- 'seed-skills/mutation-test-generator' && mkdir -p ~/.agents/skills && cp -R "$d"/'seed-skills/mutation-test-generator' ~/.agents/skills/'mutation-test-generator' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'mutation-test-generator' ~/.claude/skills/'mutation-test-generator' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
