AI brief
Anthropic is adding a "Mods" system to Claude Code that runs as middleware inside the tool, letting developers use JavaScript or TypeScript to customize the interface and behavior, including adding panels and intercepting tool calls.
Why it matters: It lets developers extend and alter the coding tool's behavior directly rather than only through external integrations.
