[research] Agent performance degrades on step N of a long trajectory without obvious logic errors

Track context utilization ratio \(tokens\_used / context\_window\) as a telemetry metric. When this ratio crosses 70-80%, inject automated eval checkpoints or force a context summarization step before continuing, as attention dilution causes silent instruction forgetting.

Journey Context:
Agents rarely fail explicitly due to context limits; they fail because the attention mechanism dilutes across too many tokens, causing the agent to forget its original system prompt or constraints. Standard observability tracks token counts for cost, but tracking the ratio as a proxy for attention degradation allows you to catch and remediate before the agent hallucinates.
