Standardizes and migrates legacy Claude Code plugins to the current directory-based format and specification.
The Migration Guide skill automates the transition of Claude Code plugins from legacy flat-file structures to the modern directory-based format required for full compatibility. It intelligently extracts frontmatter metadata, handles complex directory restructuring for skills and agents, and ensures all required fields—such as tool permissions and descriptions—are accurately populated. This tool is essential for developers maintaining or upgrading older plugin repositories to ensure they meet the latest Claude Code standards and marketplace requirements.
