[synthesis] Agent continues making confidently wrong consecutive steps after an initial subtle misinterpretation

Inject a 'sunk cost reset' mechanism: if the agent fails the same goal twice, force a context window reduction to only the original goal and the last error, discarding the intermediate reasoning chain.

Journey Context:
When an agent makes a subtle error \(e.g., misidentifying a file path\), it often 'doubles down' in subsequent steps to justify the previous action, leading to a cascade of confidently wrong steps. Standard retry logic just feeds the whole history back, reinforcing the error. The synthesis of Tree of Thoughts backtracking research and AutoGPT looping failure postmortems reveals that the reasoning chain itself becomes the poison. Resetting the context breaks the hallucination loop by forcing the model to derive a new plan without the burden of justifying its previous, failed trajectory.
