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

# frontmatter-guard

Canonical skill: `skills/frontmatter-guard/SKILL.md`

Read that file and follow it exactly. Resolve relative links against `skills/frontmatter-guard/`, not this wrapper.

Cursor has no Skill tool. Treat "invoke the frontmatter-guard skill" as: Read `skills/frontmatter-guard/SKILL.md`.

How to install

The exact contents, by fingerprint

mdr add kanevry/session-orchestrator/frontmatter-guard@sha256:3061baacb7661ce9

The line at the top of this page pins the label git:20260825.0626387, 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.
