TL;DR: A Claude Code marketplace is a GitHub repo with a specific folder structure. You create plugins inside it, push to GitHub, and anyone (including yourself) can install your plugins with two commands. This article shows you how to scaffold one from zero and add your first plugin. A one-command setup script comes later in the series, and auto-versioning plus release CI come pre-wired as a bonus in the starter template.
Every time I switched between my work machine and home setup, or got a new laptop, I'd lose an hour reinstalling the same Claude Code plugins and setting up the same tools. Wrong versions, configs I'd forgotten to copy over, the whole thing rebuilt from nothing. So I built a marketplace - a single GitHub repo that holds all my plugins and keeps them versioned.
Before we get into the structure: you can skip the scaffold entirely and use the starter template directly (link below). The rest of this article explains its structure.
