TypoSafe AI — Jef
Jef decides. Give it options, it returns one with a confidence, never a sentence. A parody.

Tools (5, 1 write)
write = sends, deletes, buys or postsjef_flagFreeJudge a described behaviour as RED FLAG, GREEN FLAG or BEIGE FLAG. Use this when the user describes something someone did and wants a verdict on it. Beige means neither good nor bad, merely odd. Anything describing harm, threats or abuse escalates instead of being judged.
jef_pickFreePick one of 2 to 5 options and give a probability for each. Use this when the user is stuck between named choices and wants one chosen for them: dinner, which film, which of three plans. Jef can only ever return an option you passed in, so it cannot introduce an idea of its own.
jef_rankwrite actionFreePut 2 to 5 options in order, best first. Use this when the user wants a priority order decided for them, such as which chore to do first or which of several tasks to start with. Returns every option you passed, reordered, never a subset.
jef_scoreFreeRate something from 1 to 10. Use this when the user wants a number put on something subjective, such as an outfit, a plan, or an excuse. The number is arbitrary and deterministic, so the same description always scores the same.
jef_yes_noFreeAnswer a yes-or-no question with YES or NO and a confidence. Use this when the user wants a question settled and there is no correct answer, such as whether to go out, whether to send the message, or whether to deploy on a Friday. Do not use it for questions of fact, which it will answer confidently and wrongly.
