Create the marketplace file

Create .claude-plugin/marketplace.json in your repository root. This file defines your marketplace's name, owner information, and a list of plugins with their sources.

Each plugin entry needs at minimum a name and a source that tells Claude Code where to fetch it from. See the full schema below for all available fields.
