    Claude Code adds mods for customizing behavior, UI, and features

    Boris Cherny says users can now customize how Claude works and looks just by prompting it. He argues that different working styles call for different Claude experiences and encourages sharing mods as plugins. In the quoted announcement, @ClaudeDevs says Claude Code mods can change behavior, customize the UI, and add users’ own features; users can write them with a few lines of TypeScript or have Claude build them, then install them with /plugin in the CLI or desktop app.

    Why it matters: Packaging customizations as shareable plugins lets people with different working styles exchange changes to Claude Code’s behavior, interface, and features through the same installation workflow.
