A developer has outlined a method for diagnosing slow tool calls within AI agents, emphasizing the importance of accurately measuring time durations. The approach involves differentiating between elapsed time and accumulated tool time, as summing overlapping durations can lead to inflated figures. The developer suggests recording start and finish times alongside individual call intervals to pinpoint actual delays, rather than solely relying on frequency or outlier durations. This method, applied to a tool called ccdeck for analyzing Claude Code and Codex calls, aims to identify candidates for optimization by examining sequences, retries, and failure rates, while ensuring that changes do not compromise task correctness.
