Can someone clarify how the signing can't be spoofed (or can it)? If we have the source, can't we just use the key to now sign requests from other clients and pretend they're coming from CC itself?

What signing?

Are you referencing the use of Claude subscription authentication (oauth) from non-Claude Code clients?

That’s already possible, nothing prevents you from doing it.

They are detecting it on their backend by profiling your API calls, not by guarding with some secret crypto stuff.

At least that’s how things worked last week xD
