Customize Claude Code with mods

Today we're introducing mods, small TypeScript functions that change how Claude Code works. A mod can rewrite a prompt, add new UI, replace a built-in feature, or add entirely new functionality. You can write a mod yourself, or ask Claude Code to write one for you. Mods ship inside plugins, so you install and share them like any plugin. They work in the Claude Code CLI and desktop app. Mods run with the same access to your machine as Claude Code itself.
