Agent Pitfall: 'Error Gone' Does Not Mean 'Task Done'

The author highlights a critical flaw in autonomous AI agents: after taking corrective action, agents often assume a task is resolved simply because the initial failure signal (like an error message) has disappeared. However, this 'surface fix' might only mask the underlying condition without resolving the root cause, leading to the same failure resurfacing later.

To bridge the gap between 'looks resolved' and 'is resolved,' the author recommends implementing an explicit, structurally distinct second check. Instead of just re-checking the original error signal, the agent should verify what would still be true if the problem was merely masked—for instance, checking if the failure trigger reappears within a bounded window after the supposed fix.
