Across the AIDev dataset, nearly half of fixes from Copilot, Devin, Cursor, and Claude are rejected, sorted into incorrect implementation, CI failures, inability to execute the fix, and low priority (arXiv). The fix the authors push: better model guidance on implementation approach and self-validation before submitting. This is the empirical floor under all the "agents replace review" hype. Half of what they produce doesn't land.
