This Skill addresses the maintenance difficulties, poor reusability, and potential security risks that developers face when creating Claude Agent Skills due to non-standard structures. By analyzing the SKILL.md file, it evaluates whether the Skill adheres to the best practices of an "on-demand instruction package," helping developers build more robust and portable Skills.
To use it, simply request a Skill review from the AI, such as "Check my skill" or "Is this skill specification compliant?" The Skill will then automatically trigger. It conducts an in-depth analysis of your Skill description, file structure, externalization of scripts, hardcoded paths and keys, and other issues, generating a detailed scoring report.
It is ideal for agent developers, full-stack developers, and DevOps engineers, especially those who want to follow official specifications and improve Skill quality and team collaboration efficiency. It is particularly useful for scenarios requiring quick validation of new Skill structures or refactoring legacy Skills.
It is recommended to have the SKILL.md file or its content ready for review before use. The tool primarily provides structural review and suggestions; specific code refactoring needs to be done manually by the developer or in combination with other tools. Ensure that no real sensitive key information is included during the review to prevent leaks.
Key Features
Unlike general-purpose code review tools, it specializes in deep inspection of the SKILL.md structure and official best practices for Claude Agent Skills, providing prioritized, actionable fix suggestions, and can even perform refactoring on your behalf.
Limitations
This Skill primarily focuses on the structure and specifications of the Skill and does not involve functional testing or performance evaluation of the Skill's internal business logic.
FAQ
What does the Claude Skill Inspector check?
It primarily checks the description quality of SKILL.md, file length, progressive disclosure (references/splitting), externalization of scripts, portability (no hardcoded paths), and security (no hardcoded keys).
How can I use it to optimize my Skill?
Simply tell the AI "Check my skill" or "Split the skill." It will provide a score and specific refactoring suggestions, and can even restructure the SKILL.md file on your behalf as instructed.
