Useful, with limits.
These counters come from the harness and transport. They are preserved as observed; AgentBattler does not infer missing values or treat token/cache figures as directly comparable billing data.

Open the underlying record.
The semantic trace retains visible messages, tool calls, tool results, usage events, and stderr after credential-shaped values and host paths are sanitized. It does not expose hidden chain-of-thought.
