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.\n\nWhen we first launched, most people approved every permission prompt by hand and mostly used Claude to answer questions and write tests. \n\nToday, the default is trusting Claude&#8217;s judgment to auto-approve. Claude does large migrations and builds new products. \n\nHelping build Claude Code into an industry-defining product has been the journey of a lifetime. \n\nThank you to the incredible team behind Claude Code, Cowork, and Tag. These products are the sum of thousands of great ideas from you. I&#8217;ll miss working with you all.\n\nThank 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.\n\nExcited to see what you all make next!<\/p>&mdash; cat (@_catwu) <a
