What it is
An experimental bot that lets TypeSafe Jev play Slay the Spire 2 on your computer, choosing cards, targets, rewards, routes, and purchases. A local dashboard shows its choices, competing options, and estimated outcomes for players who want to watch or step in.
How it uses Jev
Jev is the only AI model making gameplay choices. The app reads the visible game state through a local bridge, builds legal actions and short combat plans with estimates, then asks Jev to choose. It checks the state is current and executes only the first action, then observes again.
Primitives:choice
Technique worth stealing
Ask Jev to choose among legal actions built from visible state, then execute only the first action and re-observe.
Try it
Set TYPESAFE_API_KEY, run npm start, open http://127.0.0.1:4317, and press Autoplay.
