Really?

I just did the LoC measure that isn't "official" but actually closer to how AI would read it: I.e. simply actual lines. Never mind "context window".

Just in the actual source folder there are 1.9 million lines. That's not tokens. Lines. Not even LoC as per some official canonicalized definition. Various languages. ~15 year old code base.

We work with Claude just fine.

For variable measures of "fine" depending on how much devs just trust whatever Claude spits out ;)
