[synthesis] Agent reasoning degrades in long sessions due to accumulated tool error messages consuming context window space

Implement a sliding context window or summarization step that aggressively compacts or removes consecutive tool error logs, and monitor the ratio of error tokens to total context tokens as a leading quality indicator.

Journey Context:
When a tool fails intermittently, agents often retry. Each retry appends an error trace to the context. The agent doesn't crash, but the error logs consume the finite context window, pushing the original system prompt or early reasoning out of scope. The agent then hallucinates or loses the plot. Teams look at the final error rate, but miss that the context was polluted. The synthesis is that context composition \(percentage of error tokens\) predicts quality decay better than aggregate error rates alone.
