Claude Code just got a major upgrade. Anthropic introduced a new "Mods" system, allowing developers to rewrite their AI coding tool from the inside. Using JavaScript or TypeScript, users can reshape the interface and behavior, add custom panels, and even intercept tool calls. This is essentially middleware running directly within Claude Code, giving unprecedented control. It means developers can deeply personalize the AI's functionality, making it truly adaptable to specific workflows. It's a powerful move, putting serious customization into the hands of its users.
