Validate skill/command file format and structure. Use after creating or editing a skill, before committing skill changes, or when a skill fails to load or trigger.
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
# Skill File Validator
Validate skill files for correct format against the official Claude Code spec.
---
## Validation Target
- With argument: validate specific file
- Without: validate all `.claude/skills/*/SKILL.md`
---
## Frontmatter Reference (official fields)
Skills support these fields. Only `description` is meaningfully required (a
skill with none of these still loads — `name` defaults to the directory name).
```yaml
---
name: skill-name # Optional: defaults to directory name; lowercase, hyphenated
description: What it does # Recommended: shown in / menu and used for triggering
when_to_use: When to reach for it # Optional: appended to description for triggering
# (description + when_to_use truncated at 1,536 chars in listings)
user-invocable: true # Optional: default true; false hides from / menu (Skill tool still works)
model: sonnet # Optional: any /model value (sonnet, opus, haiku, fable, best,
# default, opusplan, sonnet[1m], opus[1m], a full model ID) or inherit
effort: medium # Optional: low, medium, high, xhigh, max

How to install
mdr add claude-world/director-mode-lite/skill-check@sha256:14cc402626d4cb26The line at the top of this page pins the label git:20261021.8facda8, 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.
