Sorry to say but this workflow just isn't great unless you're working on something where AI models aren't that helpful -- obscure language/libraries/etc where they hallucinate or write non-idiomatic solutions if left to run much by themselves. In that case, you want the strong human review loop that comes from crafting the context via copy paste and inspecting the results before copying back.

For well trodden paths that AI is good at, you're wasting a ton of time copying context and lint/typechecking/test results and copying back edits. You could probably double your productivity by having an agentic coding workflow in the background doing stuff that's easy while you manually focus on harder problems, or just managing two agents that are working on easy code.
