To review a Claude Code SKILL.md file for marketplace compliance, run an audit against the target file path to verify frontmatter fields, directory structure, body length, and reference materials, generating a structured quality report.

Valid SKILL.md frontmatter requires specific fields like name and description, while enforcing constraints on character length, allowed character sets, and reserved words to ensure Claude Code skills meet official guidelines.

Checking SKILL.md reference files and directory structure involves verifying that the layout matches marketplace guidelines and validating that any referenced files exist at the expected level-1 depth paths during a pull request review.

You can automate prompt-injection detection in Claude Code skill instructions by running a safety audit that flags potential prompt-injection or data-exfiltration concerns within the SKILL.md content and its instructions.

Body length requirements for a Claude Code SKILL.md file dictate that the content must meet specific length thresholds, include clear examples, maintain consistent terminology, and define a clear workflow to pass quality assessment.

You should use an automated SKILL.md linter over manual review when pre-validating new skills before marketplace submission or during PR reviews, ensuring consistent enforcement of structural and safety constraints without human error.
