I'm looking for a short story that someone on here wrote.

It was about free will. The story opens with the main characters approaching a space station built by an old race, operated by a custodial AI. The AI keeps predicting what they're going to do and say in advance. The first mate character gets agitated, the captain keeps her cool. Then there's some sort of disaster (approaching enemy fleet?), they have to get out fast, and the captain makes use of the AI's simulations of them to get a good outcome.
