Report #88769
[synthesis] Agent loops derail silently without error after multiple tool calls due to semantic frame shifts
Implement intent anchoring: re-inject the original task description immediately before every tool call boundary, not just at conversation start, to re-ground the agent's goal representation
Journey Context:
This is not simple context length exhaustion \(which throws errors\) but semantic drift: tool outputs introduce new semantic frames that overwrite the agent's intent without triggering 'I don't know' responses. OpenAI function calling evals show models successfully complete tool chains while completely forgetting the original user request. Common mistakes include relying on system prompts \(compressed by tool outputs\) or periodic reminders \(which don't synchronize with frame shifts at tool boundaries\). Alternatives like increasing context window fail because the issue is attention mechanism focus, not token count. The correct pattern binds re-grounding to the tool-call boundary, treating each tool interaction as a potential frame shift requiring explicit intent re-injection.
