Also this rewards dynamic languages over typed languages, penalizes comments, descriptive function names, etc. Though frankly, it'd be interesting to see whether AI would work better with a project in Javascript that barely fits in context, or the same thing in typescript that overflows. I could imagine either, but my guess is "it depends". Though, "depends on what" would be interesting to know.
Still, this seems useful for being able to see at a glance. I have no idea where most of my own projects would land.
Never thought about the impact of comments, perhaps there is value in stripping those out of read file tools
