someone went through the leak and opened a proper pull request to open source it

https://github.com/anthropics/claude-code/pull/41518

the file tree looks less messy than in that screenshot, but damn, I didn't think it would be 514k lines

I wouldn’t be surprised if a lot of this was AI coded. Which would result in this kind of bloat.

An earlier one has 81 approvals

The whole repo is such a mess.

First it was the source code, than a Python rewrite and not it's "Claw Code". The issues are just AI spam. I'm really curious where this is going.

actual open source option, fwiw

Well Well Well.

Looks like the shoe is on a different foot.

Content looks legit, but I’d be super careful about running it. Who knows what got added to that zip file.
