Writing documentation, amongst other things, has been a save for me. I use it to understand new codebases quickly, create the documentation boilerplate for the code I'm working on that needs better docs, or update/rewrite outdated ones. When the codebase fits in the context window, it's simple. But even if I'm working on a larger thing, it takes a bit of RAG-alike effort to build knowledge topology, and then it's super easy to get docs on (the actual!) architecture, specific components, and all the way down to atomic function level.
