[synthesis] Agent confidently makes multiple consecutive wrong steps because it reinforces its own hallucinated state

Inject an independent sanity check tool that queries an external ground truth \(e.g., a read-only database or file system state\) before executing state-mutating actions, breaking the self-reinforcement loop.

Journey Context:
When an agent hallucinates a state \(e.g., 'I created the file'\), it feeds that hallucinated state back into its context. In the next step, it reasons based on this false premise \('Since the file exists, I will now edit it'\), leading to a cascade of confidently wrong actions. People try to fix this by adding 'be careful' to the prompt, which fails. The real fix is structural: an independent verification step that doesn't rely on the agent's internal monologue. The tradeoff is increased latency/cost per step vs preventing catastrophic cascading failure.
