Cat Wu, a product lead on Claude Code, has left Anthropic

Cat Wu announced on X that her last day at Anthropic was Friday, October 30. She joined the Claude Code team about two years ago, when it was a small internal tool, and thanked the teams behind Claude Code, Cowork and Tag.

In her post she looked back on how use of the tool changed: at launch most people approved every permission prompt by hand and used Claude mostly to answer questions and write tests, while today the default is trusting Claude's judgment to auto-approve, and Claude does large migrations and builds new products. She did not say what she will do next.
