Testing TypeSafe as the decision layer for an AI game companion.

It reads the player’s message and game context, then returns an action, destination, and confidence. Game code makes the character act. Dialogue is prewritten; TypeSafe decides what happens next.

Where this case fits

Filed under games & playable demos, coding & developer tools. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the games & playable demos page.
