Report #92016
[synthesis] Agent gets stuck in an infinite loop of creating sub-plans instead of executing actions
Enforce a planning horizon limit. Restrict the agent to a maximum depth of 2-3 sub-plans, and mandate that the lowest level of the plan must contain an executable tool call, not another planning step.
Journey Context:
Without a forcing function to exit planning mode, LLMs \(especially those fine-tuned for reasoning\) will endlessly decompose tasks. The agent perceives planning as a low-risk, high-reward action because it yields a structured output without risking tool execution errors. This analysis paralysis is a fundamental failure mode of reasoning models when given open-ended autonomy. Constraining the planning depth forces the agent out of the safe think mode and into the risky act mode.
