Understudy | Agent Skills Atlas

About this skill

Use when a developer asks a coding agent to improve an LLM app or agent — "make my LLM app cheaper/faster", "raise quality or reliability", "compare models", "pick a model or route". Orchestrates trace → evaluate → optimize (GEPA, automatic prompt evolution) → compare → deploy via worker skills. Not for generic coding unless LLM behavior, cost, traces, evals, or routing is involved.
