Why isn't my skill loading in the Claude Code menu?

This is often caused by a mismatch between the directory name and the name field in your SKILL.md. Validate-skills detects these naming mismatches and suggests the correct kebab-case format.

How does it improve skill security?

The validator scans your scripts for dangerous commands like 'rm -rf' without path validation, 'eval', or 'mkfs', providing safer alternatives to prevent accidental data loss.

Does this work with my pre-commit hooks?

Yes, validate-skills provides exit codes (0 for success, 1 for warnings, 2 for errors) making it easy to integrate into git hooks to prevent broken skills from being committed.

Can it fix tool permission errors?

Yes, it identifies if you have used incorrect capitalization for tools (e.g., 'bash' instead of 'Bash'), which is a common reason why Claude might refuse to execute a command.

개발자 도구

Validates Claude Code skills for schema compliance, naming conventions, security vulnerabilities, and documentation standards.

The validate-skills skill is an essential linting utility for developers building custom capabilities for Claude Code. It provides automated checks for common configuration errors such as case-sensitive tool names, mismatches between directory names and skill metadata, and missing documentation. Beyond syntax, it serves as a security layer by scanning shell scripts for dangerous command patterns like unvalidated deletions, ensuring that every skill you build is robust, secure, and ready for production use.
