plugin-validation

To validate Claude Code plugin structure, run the validation script on your plugin directory. It checks plugin.json and SKILL.md frontmatter, verifies references for commands, skills, agents, and hooks, and generates a lint-like report of configuration errors.

Plugin metadata validation is the process of checking plugin.json and SKILL.md files for required fields like name and description. You need it before publishing a plugin to the marketplace to catch structural issues and ensure format compliance early.

You can lint plugin.json and check SKILL.md frontmatter by running the validator script. It enforces required fields such as name and description, checks reference coherence across commands, skills, agents, and hooks, and highlights warnings to guide fixes.

The Claude Code plugin validator requires no external dependencies to run. It operates as a standalone shell script that analyzes your plugin directory structure and metadata directly to catch configuration errors.

Your Claude Code plugin validation report shows missing frontmatter fields because the validator enforces required metadata like name and description in SKILL.md. It generates these lint-like warnings to guide you in fixing format compliance issues.
