I wouldn’t say that’s exactly the case. Not to denigrate the author or anything, but this library is a relatively minor part of what Anthropic is doing. It’s a UI manipulation library, specifically one that simulates keyboard and mouse inputs. While something like that is certainly necessary for the project in question, it’s not anything that couldn’t be rewritten in-house without too much difficulty, especially since they’re only using a subset of the platforms supported by the library.

I’m sure that working on this project has provided the author with expertise in this area that Anthropic could benefit from, and so in that sense it’s still a shame that they wouldn’t give him an interview, but that’s really all that can be said about it.
