Validates and scores SKILL.md files against the agentskills.io specification; use when linting skills for cross-agent compatibility, description quality, or capability graph structure.
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
TraceMantle is a local static analyzer for SKILL.md files. It validates frontmatter structure, scores advisory description features, checks file references, and extracts a capability graph from heading and backtick-reference patterns. Run it before committing a skill, plugging it into CI, or publishing to a skill registry. ## Prerequisites - path - the SKILL.md file or directory to validate - prompt.txt - optional file path for a saved agent prompt (critique or graph extraction) - response.json - optional file path for an agent-provided JSON response ## Validate a skill Pass `path` to `tracemantle` for a full structural check against the agentskills.io specification. Validates name constraints, description quality, body sizing, file references, and cross-agent compatibility. The `validation report` is written to stdout. Exit codes: 0 no errors, 1 errors found, 2 input error (missing file), 3 symbolic passed but semantic critique flagged errors. ```bash tracemantle <path> tracemantle <path> --format json ``` ## Review a skill with an agent …

How to install
mdr add moonrunnerkc/skillcheck/tracemantle@sha256:4703349ddee511ceThe line at the top of this page pins the label v1.7.0, 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.
