Anthropic releases Claude Code Mods for custom plugin development

Anthropic has released Claude Code Mods, a new feature allowing developers to integrate custom JavaScript or TypeScript modules into its Claude Code environment. These 'mods' function as middleware, capable of rewriting prompts, managing tool calls, and redacting secrets, with access to system processes like file system and execution. While designed for extensibility, the mods are not sandboxed, meaning they have the same system reach as Claude Code itself, necessitating careful installation from trusted sources. Anthropic is already using this mod system for its own features, such as AGENTS.md support and a /diff pane, and enterprise plans include a default security mod to prevent risky overrides. AI

IMPACT Extends developer capabilities within AI coding environments, potentially increasing adoption and customization.
