This is quite a short list, maybe someone's agent can help expand it

Found this gem today: https://github.com/pmatos/jsse/ - "An agent-coded JS engine in Rust. I didn't touch a single line of code here... didn't even create this repo by hand -- my agent did that."

Passes 99.96% of test262 - that's more than V8 & co!

Gave me a good chuckle. Give it a week and some attention and this list could take the crown for longest markdown file on Github. I'd unironically read through it though.
