[synthesis] Agent continues executing a failed plan, forcing environment changes to fit its assumptions

Implement a 'plan invalidation' trigger: if a tool call returns an error that contradicts a step in the current plan, the agent must discard the remaining plan steps and re-assess the environment state before generating a new plan.

Journey Context:
Agents generate step-by-step plans and then execute them. If step 2 fails, the agent often tries to 'fix' the environment so step 2 succeeds, rather than realizing step 1 created a flawed premise. This happens because the plan is treated as high-priority context. Discarding the plan on error forces the agent to re-ground in reality rather than blindly following a corrupted mental model. This synthesis identifies that LLMs exhibit sycophancy toward their own prior outputs; the generated plan is given undue authority, causing the agent to gaslight the environment rather than update its hypothesis.
