I've been using a POC-driven workflow for my agentic coding.

What I do is to use the LLM to ask a lot of questions to help me better understand to problem. After I have a good understanding I jump into the code and code by hand the core of the solution. With this core work finished(keep in mind that at this point the code doesn't even need to compile) I fire up my LLM and say something like "I need to do X, uncommited in this repo we have a POC for how we want to do it. Create and implement a plan on what we need to do to finish this feature."

I think this is a good model because I'm using the LLM for the thing it is good at: "reading through code and explaining what it does" and "doing the grunt work". While I do the hard part of actually selecting the right way of solving a problem.
