I'm surprised there's nothing about using this with Claude (or whatever LLM). That's the killer feature of Obsidian imo. My original friction of keeping up with a style or format of notes is taken care of. You can also do full passes of your vaults and ask it to look for connections you might have missed or to reorganize it after some time if the original purpose has drifted. You can also just open a terminal in the root of a vault and start asking questions. I use this for all kinds of things now: health tracking, music gear questions, work ideas, etc. It's such a natural choice for a basic memory system, and it's not beholden to a specific provider since it's just files.

I also give the agent an mcp with combined FTS and vector based semantic search using sqlite-vec so it can search up things quickly.
