Report #64479

[agent\_craft] Agents either reason without acting \(hallucinating tools\) or act without reasoning \(brute force tool use\), leading to inefficient or incorrect execution

Implement an explicit thought-action-observation loop where the model must output reasoning \(Thought:\) before selecting a tool \(Action:\), then pause to process the observation before the next iteration; prohibit batching multiple actions in a single turn

Journey Context:
Simple tool calling allows the model to pick tools immediately, but without reasoning, it often selects suboptimal tools or wrong parameters. Conversely, forcing CoT without tool access leads to hallucinations. The ReAct insight is that interleaving reasoning traces with tool executions creates a structured log that grounds the model's subsequent reasoning in actual observations rather than hallucinated states. The hard-won nuance is that the loop must be strict: the model should not be allowed to generate multiple actions in one turn \(batching\) unless they are provably independent, as this breaks the observation feedback cycle.
