I do not claim this is the world’s most incredible agent harness; in fact, I explicitly have tried not to “hyper engineer” this to be like the best chance that exists to beat Pokemon. I think it’d be trivial to build a better computer program to beat Pokemon with Claude in the loop.
This is like meant to be some combination of like “understand what Claude’s good at and Benchmark and understand Claude-alongside-a-simple-agent-harness”, so what that boils down to is this is like a pretty straightforward tool-using agent.
