Marketplace Plugin Creator

A Cowork skill that helps you convert skills and projects into GitHub-hosted marketplace plugins that install correctly from the Cowork "Add marketplace" dialog.

What it does

• Creates the required .claude-plugin/marketplace.json and plugin.json manifests
• Sets up the correct skills/{name}/SKILL.md directory structure
• Troubleshoots common issues like "no skills or agents" showing up
• Handles both single-plugin and multi-plugin marketplace repos

Install

Add this as a marketplace in Cowork settings:

alnutile/marketplace-plugin-creator

Usage

Just ask Claude things like:

• "Make this a marketplace plugin"
• "Why doesn't my plugin show skills?"
• "Set up my repo as a Cowork plugin"
• "Publish this skill to GitHub"
