where did we get this url? who own this bucket?
Can we please not normalize putting random bucket url? Isn't this how a supply-chain attack works? :(

Hi! Thanks for raising your concerns.
I think in this case we should be fine. The recommended way of Claude Code installation is:
curl -fsSL https://claude.ai/install.sh | bashWhile working on migration from npm installed Claude Code to the script based installation, I decided to simply save that
install.shscript assrc/claude-code/bootstrap.shand run it like here - I'm not a fan of downloading a script and piping it into bash right away.So the whole content of
src/claude-code/bootstrap.shis the actual Claude Code installation script, and the bucket is owned (or at least should be) by Anthropic.To be honest, I must have missed this part of the documentation about native Linux repos being supported, maybe that's the better way - I will take look into that in free time and test
