[synthesis] Agent confidently executes multi-step plan based on incorrect early assumption

Inject sanity check steps in the agent's plan that force it to re-evaluate the initial premise against intermediate state before proceeding to irreversible actions.

Journey Context:
Agents often use Plan-and-Execute patterns. A common failure is that the LLM commits to a plan in step 1, and subsequent steps are just rationalizations of that plan, even if step 2's output contradicts step 1's assumption. This is akin to confirmation bias. The synthesis is combining the Plan-and-Execute pattern with the observation of LLM sycophancy/confirmation bias, revealing that agents will twist intermediate observations to fit a flawed initial plan rather than pivot, leading to confident multi-step wrongness.
