I regret using the term "one-shot", because my reality isn't really that. It's more that the first shot gets the code 80-90% of the way there, usually, and it short-circuits a ton of the "code archaeology" I would normally have to do to get to that point.

Some bugs really can be one-shotted, but that's with the benefit of a lot of scaffolding our company has built and the prompting process. It's not as simple as Claude Code being able to do this out of the box.
