Schliff is a scorer for AI instruction files by Zandereins, licensed MIT. It rates AGENTS.md, SKILL.md, CLAUDE.md and .cursorrules against a versioned rubric of eight dimensions, with no language model in the scoring and no network calls, so the same file gets the same score on every machine. The README shows a sample run that lists structure, operational coverage, efficiency, composability and clarity, and it adds anti-gaming checks and a security dimension. It installs as a Claude Code plugin with slash commands such as /schliff:auto and /schliff:doctor, and also as a Python package with uvx schliff score. We would suggest it to teams that want a CI gate on their instruction files. The limit is that a score measures structure, not whether an agent behaves better. The repository was last pushed on 10 November 2026, as read on 11 November. We have not run it ourselves.
