Jev Plays Pokémon Red shows the decision-model pattern: the harness lists legal moves with facts, and the model only picks one
A Show HN from Christian Mathiesen of Frigade hit 214 points (repo christianmat/jev-pokemon, GPL-2.0, created 2026-09-25). A Node Game Boy emulator reads RAM, the harness lists the legal options with type matchups, damage estimates and distance to the next objective, and TypeSafe's Jev picks each menu answer, catch, team swap and battle action through Vercel AI Gateway, throttled to 90 calls a minute. The harness never writes game memory, hides hidden items, checks progress against real event flags, and handles repeated failures by tagging tried options and reloading a checkpoint. It is a clean reference for building classifier-style agents without free-text generation.
