Hey, Steve from tldraw here. We use AI tools to develop tldraw. The tools are not the problem, they're just changing the fundamentals (e.g. a well-formed PR is no longer a sign of thoughtful engagement, a large PR shows more effort than a small PR, etc) and accelerating other latent issues in contribution.
About the README etc: we ship an SDK and a lot of people use our source code as docs or a prototyping environment. I think a lot about agents as consumers of the codebase and I want help them navigate the monorepo quickly. That said, I'm not sure if the CONTEXT.md system I made for tldraw is actually that useful... new models are good at finding their way around and I also worry that we don't update them enough. I've found that bad directions are worse than no directions over time.
