Claude leaked and now they did a wildcard DMCA notice to all @github repos mentioning claude? I just got one on my repo, which isn't the leak but a fork of the official @AnthropicAI repo 😂 I love you @AnthropicAI, but maybe a little careful with vibing everything? [image]

@wongmjane @BenLesh Mistakes happen. As a team, the important thing is to recognize it's never an individuals's fault — it's the process, the culture, or the infra. In this case, there was a manual deploy step that should have been better automated. Our team has made a few improv…

After looking through the Claude Code codebase a little, you can tell that it's heavily written by AI. It's seriously overengineered and complex to a fault. The code isn't as sloppy as I thought it would be, but I hope they've got tests somewhere. Main.tsx is MASSIVE.

I like how the Anthropic Claude Code team is being chill about the code leak. What's leaked is leaked. 70k forks, Python & Rust versions on GitHub, there's no way back. One thing is clear from reading the code: harness engineering is hard and deeply non-trivial. I think more

don't forget last time Anthropic, in their infinite PhD level wisdom, leaked their own source code (Feb 25) they DMCA'd all repos that had their code. Careful storing the code because Anthropic will have no mercy!
