Check that a Python change is caught by tests: run every mutant of the changed lines and write tests until they catch them. Reports evidence instead of a diff to read.
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
# Verify a change ## Overview This skill checks that code Claude wrote or changed is actually tested. It defines the check before coding, runs every mutant of the changed lines with a pinned runner, and writes tests until the tests catch them. It reports which mutants were killed and which new tests fail on the old code, so the user can trust the change from evidence. Upstream source: [timini/agentic-verification](https://github.com/timini/agentic-verification/tree/v0.3.0/plugin/skills/verify). ## When to Use This Skill - Use after implementing a feature or fix in a Python/pytest project, before saying the work is done. - Use when the user asks whether a change is tested. - Use `@agentic-test-audit` instead to review a whole test suite rather than one change. ## How It Works Arguments: `$ARGUMENTS`. `--base` is the git revision to compare with: `HEAD` (default) checks uncommitted work, a branch such as `main` checks a whole branch. Other options go to the runner. The goal is that the user can trust the change from evidence, without reading every line. A change is verified when the tests fail if any part of it is wrong. Passing tests alone do not …

How to install
mdr add francostino/opencode-skills-collection/agentic-verify@sha256:549c097d183c59c8The line at the top of this page pins the label git:20261017.4671004, 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.
