[frontier] Agent executing irreversible actions without verification loops

Mandate 'reflect-then-act' pattern using structured self-critique \(confidence scoring 0.0-1.0, risk assessment Low/Med/High, rollback plan\) as a deterministic gate before tool execution; block actions where confidence < 0.9 and risk = High.

Journey Context:
Agents that 'think once, act once' fail catastrophically on irreversible operations \(sending emails, deleting databases, charging credit cards\). Adding 'be careful' to the prompt is ineffective. The wrong fix is human-in-the-loop for every step, which kills autonomy. The production-winning pattern is explicit 'reflection nodes' in the agent graph \(LangGraph/Anthropic pattern\). Before executing a tool, the agent must output a structured critique: confidence score \(calibrated against past accuracy\), risk level \(based on tool semantics\), and a one-sentence rollback plan. A deterministic router evaluates these fields; if criteria aren't met, the agent loops back to re-plan rather than execute. This catches 85%\+ of potential errors without human intervention while maintaining autonomy for safe operations.
