oneshit

To complete a task in a single AI-generated attempt, without any meaningful iteration or refinement.

The AI-age evolution of “one-shot”: when a model spits out an entire piece of work at once and you hope it didn’t ruin everything.

Can be used as a verb: oneshit, oneshitted, oneshitting.

“Did you actually review the code?”
“Nah, Claude oneshitted it and I pushed to production.”
