Anthropic launched Mods, small TypeScript functions that let users customize how Claude Code operates.

Anthropic announced Mods on October 1, according to two Financial_Express messages. The messages describe Mods as small TypeScript functions that change or customize how Claude Code operates.

The reported development is a customization mechanism for Claude Code. The supplied messages do not describe a new underlying Claude model or provide any model-performance measurements.

The available detail is limited to the launch, implementation language, and customization purpose. No examples, supported interfaces, permission controls, pricing, or access requirements are included, so more specific claims about Mods’ behavior are not supported by the supplied material.
