Mods Plugin Lets You Customize Claude Code's UI and Behavior Like Middleware

xiaohu · x · 2026-10-03

xiaohu introduces the Mods plugin system for Claude Code: it works like middleware, hooking into events such as message rendering, prompt submission, and tool calls so mods can modify data or take over processing. Examples include showing context-window usage above the input box, listing project agents in a sidebar for one-click launch, and hiding email addresses during screen recording. Devs can freely customize Claude Code's display and behavior.
