plugin-validator

To validate Claude Code plugin structure, this skill checks the plugin.json manifest, internal file references, and directory conventions to detect misconfigurations and broken paths. It applies comprehensive checks across manifest, structure, frontmatter, and dependencies to surface issues early.

YAML frontmatter validation checks agents and commands for required fields and verifies SKILL.md presence where applicable. It enforces frontmatter rules to prevent common configuration failures in Claude Code plugins.

Yes, you can detect circular references and broken dependencies in Claude Code plugins using dependency validation. This skill ensures all skill and agent references resolve correctly and reports any circular dependencies found.

The best way to fix broken plugin.json manifests is to run a validation pass that reports actionable guidance and recommended fixes. This skill verifies that plugin.json exists, contains valid JSON, and includes all required fields.

Claude Code plugins fail to load when internal references point to non-existent files or use incorrect paths. Structure validation verifies that all referenced files exist, paths are relative, and directory conventions are followed.
