Do you know a language other than Rust that has alternative for docs.rs? In JavaScript and Python they never bother to have any documentation or reference, one notable example that gets me frustrated these days is the openai SDK for TypeScript. There is no documentation for it. I have to go look at the source code to figure out what the hell goes on.
Yes, you can have Claude Code go through the code and make an .md file with documentation for all the public APIs. I do that for everything that doesn't provide llms.txt.
