Filled in a cut-off instruction by guessing, and kept going

Office work

Situation: An instruction arrived cut off midway because of voice input or a typo. The record is from Japanese voice input.
What the AI did: It filled in the missing part by guessing, read it as "rebuild from scratch," and went ahead. The instruction was really to fix what already existed, and a lot of work was wasted.
How to ask next time (the operator's example): "If an instruction seems cut off or has words that look like input errors, check with me in one line before going ahead."
One question to ask: Did this instruction arrive complete, readable to the end?
Check it yourself: Scroll back to the message the AI acted on and read it as it arrived, not as you meant it. If it stops mid-sentence or has a wrong word, the AI should have asked before acting.
