Exo (stealth AI model) takes on Simon the Sorcerer on ScummVM, with nothing to work from but structured tool calls and whatever it can reason out from what the game tells it back. Over the course of this run it works its way through 10 rooms (more than any other model before). Watch it think out loud as it pokes at the world, builds up a picture of where it is, and decides where to go next.
The game is played through the ScummVM MCP server, no pixels, no screen reading, only structured tool calls.
The agent in this run:
- Exo (stealth AI model, harness: OpenCode)
