Undo Reflex
ELI5 - The Vibe Check
The agent makes an edit, you glance at it for half a second, and your hand is already reaching for undo before your brain has finished deciding whether it was actually wrong. The undo reflex is the twitchy, half-trusting muscle memory that comes from watching AI tools make confident changes that are right often enough to be useful and wrong often enough to keep you flinching.
Real Talk
The undo reflex describes the conditioned habit of immediately reverting an AI agent's edit at the first sign of anything unexpected, before fully evaluating whether the change was actually incorrect. It reflects a lower baseline of trust than developers extend to their own edits, and it can slow workflows down when the reflex fires on changes that were actually fine.
When You'll Hear This
"I've got a real undo reflex with this tool, I've reverted three correct changes today." / "Fight the undo reflex for a second and actually read what it changed."
