Verified against Cat Wu’s (@_catwu) own post on X (created 2026-11-03T21:33:33Z, about 05:33 on 4 Nov 2026 Asia/Singapore): she wrote that Friday was her last day at Anthropic.
She recounted that about two years ago, when Claude Code was a small internal tool, she used it to build an RL environment—steering for many hours without writing code by hand—then joined the team after it worked. At launch, she said, most people approved every permission prompt by hand and mainly used Claude for questions and tests; today the default is more often trusting Claude to auto-approve, including for large migrations and building new products.
She thanked the teams behind Claude Code, Cowork, and Tag, and users whose feedback shaped what shipped, and said she is excited to see what people make next. The post does not name a next employer, a successor, or any model, pricing, or product-feature change. Her X bio still lists claude code + cowork @anthropicai; this report follows the post’s own wording.
