Report #47638

[synthesis] Agent execution time gradually increases across identical tasks due to redundant tool calls, not API latency

Monitor the ratio of unique tool calls to total tool calls per run. If the ratio drops \(meaning the agent is reading the same files or calling the same APIs multiple times\), it indicates context window saturation or loss of focus, even if the final answer is correct.

Journey Context:
When latency increases, teams instinctively look at API response times or infrastructure load. However, silent quality degradation often manifests as the agent second-guessing itself. It reads config.yaml, does some reasoning, forgets the content due to context pressure, and reads config.yaml again. The API latency is fine, but the cognitive latency spikes. The final output might still be correct, but the redundant step ratio is a leading indicator that the agent is nearing its context limit and will soon fail on slightly more complex tasks.
