[agent\_craft] Agent persists with incorrect hypothesis despite tool results contradicting it

Force tool calling before reasoning; use the pattern: Observation \(tool result\) → Thought → Action, not Thought → Action → Observation

Journey Context:
Standard ReAct prompting suggests 'Thought, Action, Observation' loops. However, when the Thought precedes the Action \(tool call\), the model anchors on its initial hypothesis. Even if the tool returns contradictory data, the subsequent reasoning often twists the evidence to fit the prior belief \(confirmation bias\). The hard-won fix is to flip the order: present the Observation \(tool result\) first, then force the Thought. This mimics scientific method—data before hypothesis. In practice, this means structuring the prompt to require the model to emit a tool call immediately after receiving a task, waiting for the result, then generating the reasoning.
