Report #59851

[synthesis] Model forgets early tool results or instructions in long multi-turn agent executions

For GPT-4o, implement explicit summarization of earlier tool results into the system prompt. For Claude, manage token limits but rely on its larger effective context window.

Journey Context:
As multi-turn tool chains grow, GPT-4o begins to suffer from 'context amnesia,' ignoring or contradicting tool results from >10 turns ago. Claude 3.5 Sonnet maintains better adherence to early context but suffers from latency degradation. GPT-4o agents need active context compaction/summarization, whereas Claude agents need timeout management.
