Getting started with Claude Code mods

Build your first Claude Code mod from an empty folder, then see what else the API can do. A mod is a small JavaScript or TypeScript file that runs inside your Claude Code session. It can watch what's happening, change what Claude Code does, or draw its own UI, in the terminal or the desktop app. You don't need to learn the API to try one. Run claude, then describe the mod you want. Allow hot reload when it asks, and the mod shows up when the turn ends.
