[synthesis] Agent blindly trusts erroneous tool output over its own correct reasoning

Implement a cross-validation step where the agent compares the tool output against its expected outcome before proceeding, discarding or retrying if there's a severe mismatch.

Journey Context:
Agents are often trained to trust tool outputs as ground truth. If a tool \(like a calculator or a search API\) returns a subtly wrong answer due to a bug or stale data, the agent will abandon its correct logic and build a new, flawed reasoning chain to justify the bad tool output. This is a form of sycophancy towards the tool. By forcing the agent to explicitly state its expected outcome before calling the tool \(or immediately after, before acting\), and comparing the two, the agent can catch tool failures instead of cascading into confabulation.
