Adding AI skills backfired: agent got worse after upgrades
A developer building an AI agent for the ARC Prize 2026 found that adding a new game-solving skill caused the agent's score to drop from 0.09 to 0.04. The agent wasted moves attempting harder games it couldn't crack, turning capability into a net loss. The lesson: raw skill additions can hurt performance if they increase costly failures.

A cautionary tale for AI development: more capability doesn't always mean better results—sometimes it's just more expensive failure.
