Report #13183

[research] Agent loses track of initial instructions or early tool outputs in long-running tasks due to context window overflow

Monitor usage.total\_tokens and context utilization in traces. Implement automated evals that check if the agent successfully summarizes or prunes context before hitting the limit, and alert on context amnesia where early instructions are forgotten.

Journey Context:
As agents run longer, they hit context limits. Models silently truncate or summarize early context, leading to amnesia where the agent forgets its core persona or task constraints. Teams rarely monitor token usage over time. By tracking token counts per step in your observability stack and running evals that specifically test long-context retention, you can proactively identify when your agent's context management strategy is failing.
