A skill that is intentionally missing its license frontmatter field to test the validator warning path.
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
# Missing License This fixture exercises the `validateLicense` warning in the validator. It has no `license:` key in the frontmatter and a `references/sources.md` so only the license warning fires. ## When to use - (Test fixture only — not a real skill)
Read the whole file at its exact version.
How to install
mdr add arenukvern/skill_steward/missing-license@sha256:24ce60d7e9924dbbThe line at the top of this page pins the label git:20260531.786f50f, 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.
