Report #86435

[architecture] Agent accumulates infinite working memory, eventually hitting the context window limit and truncating the most recent, critical instructions like the system prompt or current task

Implement an explicit eviction policy for the context window. Summarize the oldest N turns and replace them with a single summary block, ensuring the system prompt and current scratchpad are never truncated.

Journey Context:
Naive FIFO \(First-In-First-Out\) context truncation drops the oldest message. But in long tasks, the oldest messages might contain the original goal, while middle messages are just tool output. If the goal drops, the agent drifts. Summarization \(rolling context\) preserves the intent of past turns while freeing up token space. The tradeoff is a slight loss of granular detail, but it guarantees the agent never loses the plot.
