valid-skill

Skill validation checks your skill's structure against official standards including frontmatter, section headers, code blocks, and resource declarations. Run this validation on your completed skill.md file to catch formatting issues, missing sections, and inconsistent organization before submission, reducing review cycles.

Skills must include Quick Start, Implementation, and Mastery sections organized with principles, references, templates, and bundled resources. Validation ensures frontmatter compliance, proper sectioning, formatted code examples, checklists, cross-references, and correct template and script declarations throughout the skill.

Validation applies to skills organized with Level 1 Quick Start through Level 3 Mastery structure. If your skill uses this standard three-level framework with accompanying principles, references, and resources, validation confirms uniform content organization and reference consistency across all components.

The validation enforces clear principles, quick references, and common pitfalls documentation. It confirms that code examples are properly formatted, checklists are complete, cross-references link correctly, and bundled templates and scripts are properly declared in your skill structure.

Inconsistent skill formats create friction for users navigating between skills and increase review overhead. Standardized structure—consistent headers, frontmatter, sectioning, and resource declarations—ensures uniform user experience, faster skill discovery, and streamlined content review before publication.
