Cat Wu 宣布离开 Anthropic，回顾 Claude Code 两年

Friday was my last day at Anthropic.

Two years ago, when Claude Code was a small internal tool, I asked it to build an RL env. I steered it for tens of hours but never manually wrote a line of code. It worked, I was hooked, and I joined the team.

When we first launched, most people approved every permission prompt by hand and mostly used Claude to answer questions and write tests.

Today, the default is trusting Claude's judgment to auto-approve. Claude does large migrations and builds new products.

Helping build Claude Code into an industry-defining product has been the journey of a lifetime.

Thank you to the incredible team behind Claude Code, Cowork, and Tag. These products are the sum of thousands of great ideas from you. I'll miss working with you all.

Thank you to our users for embracing a new way of working. Your constant feedback shaped so much of what we shipped and your stories made the work so meaningful.

Excited to see what you all make next!
