You certainly can do this for code, and it’ll give you great answers. But I find that, for whatever reason, info that I consume this way has a much shorter TTL in my brain than something I wrote myself.

I’ve been experimenting with writing a living spec — API endpoints, schemas, how things work at a low enough level that the LLM can fill in the details - and that’s been working well.

It also forces me to do the hammock-driven development necessary to build the right thing, and as a byproduct it keeps the design in my head longer.
