Report #1345

[research] Agent runs hit context window limits or rate limits unexpectedly without clear telemetry

Track token utilization per tool call and per agent step in your observability stack. Set alerts on the rate of change of token usage per step, not just total tokens, to detect infinite loops or context stuffing early.

Journey Context:
Agents often fail silently by hitting the max context window, resulting in truncated inputs to the LLM, which causes bizarre, hallucinated behavior. Standard dashboards show total token count, which looks normal if the agent is doing a long task. The real signal is when a single tool call returns a massive payload \(context stuffing\) or the agent loops, causing token usage per step to spike. Observing the derivative of token usage across the trace spans allows you to kill the run before it hits the hard limit and wastes compute.
