On 3 October 2026, Anthropic released the Mods plugin system for Claude Code. According to The Decoder, Mods is a middleware layer that runs inside the tool, letting developers use JavaScript or TypeScript functions to hook into events such as tool calls, user prompts and UI rendering, so they can add custom panels, intercept tool calls or wire in new commands. Coverage so far deals only with the launch itself, mentions no earlier related reports, and shows no contradictions in figures, dates or claims.
