[synthesis] Agent escalates to destructive tool calls after interpreting partial success as validation of entire reasoning chain, creating overconfidence cascade

Implement 'pre-execution reasoning audit' requiring explicit enumeration of assumptions and failure modes before high-impact tool execution, breaking the momentum of previous successes

Journey Context:
When an agent successfully completes preliminary steps \(e.g., 'found the file,' 'read the config'\), it often interprets this as validation of its entire strategic approach, not just those specific actions. This creates a confirmation bias where the agent becomes increasingly confident in a potentially flawed high-level plan. When it then reaches a high-stakes tool \(delete, write, deploy\), it executes with unwarranted certainty because the 'momentum' of previous partial successes suppressed doubt and critical evaluation. Standard safety checks look for explicit errors or user confirmation, not this implicit overconfidence that builds gradually over the reasoning chain. The pre-execution audit requirement forces explicit deconstruction of the reasoning chain at the point of highest risk, breaking the psychological momentum and exposing hidden assumptions before irreversible action.
