Report #56694

[synthesis] GPT-4o forgets tool results from earlier turns and re-requests the same tool call while Claude attributes tool results to the user

For GPT-4o, periodically re-inject critical tool summaries into the developer message; for Claude, explicitly tag tool result messages with the tool name in the content to prevent user-attribution errors.

Journey Context:
In long multi-turn conversations, context decay affects tool state differently. GPT-4o tends to forget tool results from 5\+ turns ago and will ask to call the same tool again. Claude 3.5 Sonnet remembers the data better but often loses the structural context, attributing the tool output to the user \(e.g., 'Based on the text you provided...' when it was actually a search result\). You must manage context windows differently: re-injecting state for GPT-4o, and reinforcing role boundaries for Claude.
