My approach is to keep the comments only with a references. My LLM based projects always have the decision log where are my decisions while working on the features are stored with the date. I found this useful to actually trace why something is in the codebase. It's much easier for both me and the LLM to navigate through the big projects where I spent months and dozens of full night sessions executing my plans with --dangerously-skip-permissions. In the morning I was answering all the model questions and iterating like that. Honestly, try that.
