[synthesis] Agent confidently executes multiple consecutive steps based on a flawed initial assumption, compounding the error

Inject a sanity check step after the first tool call in a multi-step plan, forcing the agent to evaluate if the tool output actually validates the premise before proceeding.

Journey Context:
When an agent forms a hypothesis and calls a tool, if the tool output is ambiguous or slightly misinterpreted, the model often rationalizes the output to fit its hypothesis \(confirmation bias\). It then calls the next tool based on this rationalization, digging a deeper hole. Single-source docs only talk about hallucination, but the synthesis is that this is a cascading confirmation bias driven by the model's tendency to maintain narrative coherence. The fix isn't just prompt better, it's architecturally breaking the chain with forced reflection.
