Letting Claude Code Rewrite Itself Sounds Terrifying

Anthropic has introduced Claude Code mods, small TypeScript functions designed to let developers rewrite prompts, alter the user interface, and replace built-in features. Operating through plugins for both the CLI and desktop app, these mods hook into events like tool calls and permission requests, giving users deep control over their development environment without waiting for official updates.

• Mods run without sandboxing, possessing the exact same local machine access as Claude Code itself.
• Built-in features like the diff tool are now modular, allowing developers to turn them off or replace them entirely.
• Enterprise plans include managed settings and security defaults to prevent rogue modifications from overriding permissions.

Why should I care? Ehhh
Writing custom TypeScript to break your terminal is fun until an un-sandboxed script deletes your system files.
