agentmeasure

Check whether agent telemetry preserves measurement semantics. Use when a user asks whether retries inflate counted usage, whether an operation differs from an attempt, whether token metrics double count a subset (reasoning inside output), whether cache hits or cached replays distort counts, or wants conformance tests for agent metrics and observability claims. 中文触发：遥测语义核查、重试计数、用量口径、token 重复计数、Agent 用量指标一致性检验。
