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

# harness-engineering-skills

> Stometa's public curated Claude Code skillset — a small, opinionated set of engineering skills maintained here as one Claude Code plugin.

## What this repo is

This repository is the public canonical source for one Claude Code plugin, `harness-engineering-skills`, containing two skills: `review-loop` and `harness`. Changes are reviewed, versioned, and released here.

## Skills in this release

- **review-loop** — Cross-LLM iterative code review. Spawns a peer reviewer (Codex CLI or Gemini CLI), evaluates its findings, implements accepted fixes, and re-submits until both sides converge. Runs autonomously; humans watch via `.review-loop/<session>/summary.md`. Install: `claude plugin install harness-engineering-skills@stometa` then invoke `/review-loop` inside Claude Code.

How to install

The exact contents, by fingerprint
mdr add stone16/harness-engineering-skills/llms.txt@sha256:e60125e7a7751c99

The line at the top of this page pins the label git:20260716.27f3256, 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.
