marketplace-plugin-creator

Convert a skill, plugin, or project into a GitHub-hosted Cowork marketplace plugin that installs correctly from the "Add marketplace" dialog. Use this skill whenever the user wants to publish a skill to a marketplace, create a marketplace repo, fix a plugin that shows "no skills or agents", package a skill for distribution via GitHub, or troubleshoot plugin installation issues. Also trigger when the user says things like "make this a marketplace", "publish this skill", "why doesn't my plugin show skills", "set up my repo as a plugin", or "fix my marketplace plugin".
