Can I customize the generated files?

Absolutely. The skill provides the initial scaffolding and 'Next Steps' instructions, encouraging developers to further customize the README and component logic after generation.

Is this skill specific to a certain repository?

Yes, it is optimized for the claude-code-plugins repository structure, ensuring compliance with its specific directory hierarchy and naming conventions.

Does it handle marketplace registration automatically?

Yes, it updates the marketplace.extended.json file and executes the sync-marketplace script to ensure your new plugin is immediately recognized by the system.

What types of plugins can this skill create?

It supports the creation of Commands, Agents, Skills, MCP (Model Context Protocol) servers, and 'Full' plugins that combine multiple types into a single package.

How does the skill validate the new plugin?

It runs a suite of validation steps including shell script checks (validate-all.sh), jq for JSON syntax verification, and frontmatter validation for markdown files.
