Is YAML frontmatter validation included?

Yes, the skill specifically checks for valid YAML syntax in the header of Markdown files, ensuring no tabs are used for indentation and all required metadata fields are present.

What files does this validator check?

It validates the .claude-plugin/plugin.json manifest, agent definitions in the agents folder, skill files (SKILL.md), command files, and general file encoding across the project.

Why is my Claude Code plugin failing to install?

Installation failures are often caused by JSON syntax errors in the manifest, missing required fields like 'version' or 'author', or incorrect directory structures. This skill identifies and helps fix these issues.

Does this skill handle cross-platform path issues?

Yes, it checks for Windows path separators, case sensitivity, and line ending compatibility to ensure plugins work reliably across Linux, Mac, and Windows environments.

Can it fix encoding issues?

While its primary role is validation, the skill provides guidance on normalizing file encodings to UTF-8 and managing Git line-ending configurations to prevent corruption.
