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
# No Description Skill (synthetic test fixture) This is a synthetic Trustabl test fixture used to exercise the skill_has_description predicate. It intentionally omits the `description:` frontmatter field. It is otherwise clean: no dynamic-context execution, no external URLs, no bundled scripts, and no prompt-injection markers, so CSKILL-070 is the only skill-scope rule expected to fire — except CSKILL-085 (missing purpose language), which also legitimately fires here since the omitted description carries no purpose phrase either. If a read fails, it stops and reports the failure rather than guessing.

How to install
mdr add trustabl/agent-reliability-analyzer/no-desc-skill@sha256:c42858ffc5b3fa3dThe line at the top of this page pins the label git:20260812.c9b4ad1, 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.
