What is the difference between a project and a Claude Code plugin?

A project is a local codebase, while a plugin is a structured extension containing a manifest and skills that can be installed, enabled, and shared across different environments.

Can I use this to publish to a private team marketplace?

Yes, the skill helps generate the required marketplace.json schema and validates the source paths needed for team-based distribution.

How does Claude discover my plugin's functionality?

Claude discovers functionality via the plugin.json manifest and specific directory conventions (like /skills or /agents) which provide the LLM with metadata to trigger the tool.

Does this skill support the deprecated slash commands?

It provides legacy support for slash commands but actively guides users to migrate toward the more powerful and flexible Agent Skills architecture.

What is the role of the automated scanning phase?

The scanning phase checks for common structural errors, permission issues, and naming convention violations before you attempt to validate or install the plugin.
