What happens if there is a duplicate plugin name?

The skill performs a validation check before any write operation; if a duplicate name is detected in the marketplace.json, the operation is aborted to prevent catalog corruption.

Does this skill support private GitHub repositories?

Yes, provided your local environment is authenticated with the GitHub CLI (gh) and has the necessary permissions to access the specific repositories.

Does it automatically update the README after every change?

Yes, every add, remove, or update operation is designed to keep the marketplace.json manifest and the README tables synchronized automatically.

How does it handle plugin categorization?

The skill uses a predefined set of eight industry-standard categories, ranging from Language Servers to Output Styles, to ensure your marketplace is organized and searchable.

Can I use this to scaffold local MCP servers?

Absolutely. When adding a local plugin, you can specify MCP as a component, and the skill will generate the necessary directory structure and configuration files.
