skill-validator

Validation checks your skills, commands, agents, hooks, and plugins against specifications for structure, naming conventions, required fields, and best practices. Run the validator in your project directory to catch issues before committing or distributing, ensuring components meet quality standards and marketplace requirements.

Quality validation enforces YAML/JSON frontmatter correctness, required fields presence, kebab-case naming, semantic versioning, trigger definitions, absence of TODOs, defined workflows, usage instructions, and safety requirements. It provides actionable remediation guidance for each issue found.

You can validate individual skills in your current directory or check an entire plugin at once. The validator applies comprehensive checks across all component types within a plugin, making it ideal for pre-release validation and marketplace deployment workflows.

Run validation during development to catch structural and best-practice issues early, before peer review or committing changes. Use it again before publishing to the marketplace to verify all skills, commands, and agents meet Anthropic specifications and community standards.

Validation identifies problems in structure, format, naming, versioning, triggers, documentation, and safety checks, then provides specific remediation guidance for each issue. You can fix problems iteratively and re-run validation to confirm compliance before distribution.

Yes, install the skill-tools plugin first using `/plugin install skill-tools`. This provides the validation functionality needed to check your Claude Code components against specifications and best practices.
