Agent Tool Call Health, at a Glance

Every agent's Summary page now includes a Tool Calls section with aggregate health metrics — total tool calls, average calls per trace, tool error rate, and top tool, each with period-over-period deltas. Below the headline numbers: tool call volume over time stacked by tool, a ranked list of top tools by call count, latency, or errors, and per-tool latency (Avg/P50/P95/P99) and error rate trends.

When a retrieval tool starts flaking or an API slows down, you can now identify which tool is failing, how often, and whether it's trending in the right direction — all from the Summary page.
