What validation steps are performed after creation?

The skill runs validation scripts to check for required files, valid JSON syntax, proper markdown frontmatter, and ensures scripts are executable.

Does it handle marketplace registration automatically?

Yes, it updates the marketplace.extended.json file and runs synchronization scripts to ensure the new plugin is visible in the CLI catalog.

Is the license customizable?

By default, it generates an MIT license, but you can easily modify the generated LICENSE file within the plugin directory after scaffolding.

What types of plugins can this skill create?

It supports Commands, Agents, Skills, MCP (Model Context Protocol), and Full plugins that combine multiple components into a single package.

Can I use this for MCP development?

Absolutely. It generates a full TypeScript boilerplate including package.json with the MCP SDK and adds the plugin to your pnpm workspace.
