# Get what a simulation episode observed

> Projects one episode's session transcript into what its checks graded: the agent's replies and every tool call across the session tree, each marked whether it was recorded instead of executed. Read on demand from the session transcript through the caller's session access; an episode that started no session observes nothing.
