I often use LLMs for method level implementation work. Anything beyond the scope of a single function call I have very little confidence in. This is OK though, since everything is a function and I can perfectly control the blast radius as long as I keep my hands on the steering wheel. I don't ever let the LLM define method signatures for me.

If I don't know how to structure functions around a problem, I will also use the LLM, but I am asking it to write zero code in this case. I am just having a conversation about what would be good paths to consider.
