I am the maintainer of a library to simulate keyboard and mouse input. I didn't start the project but took over the maintenance and have since rewritten pretty much all of the code. I recently found out that Anthropic is shipping it in Claude Desktop for some unreleased feature which is probably like "Computer Use". I noticed they had an open position in exactly the team responsible for the implementation and applied. A few months later I received a rejection. The letter said that the team doesn't have the time to review any more candidates. The code is under MIT so everything is perfectly fine. It is great that a company like Anthropic is using my code, but it would have been nice to benefit from it. I wrote a slightly longer blog post about the topic here:
