Report #75780

[research] Agent suddenly fails on long tasks without obvious errors

Emit telemetry on context window utilization percentage at each agent step. Alert or trigger context-compression when utilization crosses 80%.

Journey Context:
Agents silently degrade when they approach the context limit. They don't throw a hard error; instead, they forget earlier instructions or tools, leading to loops or hallucinations. Observability must track the ratio of current tokens to max tokens per step, treating high context utilization as a leading indicator of failure.
