[frontier] Agent executes irreversible actions before getting human approval

Use interrupt/resume patterns in your agent graph. Before any node that executes an irreversible action \(API call, database write, email send, payment\), add an interrupt that pauses execution, surfaces the proposed action including tool call arguments to a human, and waits for approval before resuming from the checkpoint.

Journey Context:
The naive approach is to add ask the user first to the agent's system prompt. This fails because the agent sometimes forgets, cannot distinguish between high-risk and low-risk actions, and there is no way to pause mid-execution in a running graph. The interrupt/resume pattern solves this at the orchestration level: the graph checkpoints its state before the risky node, suspends, and emits a signal that a human must approve. The human reviews the proposed action \(the actual tool call arguments, not a vague can I proceed question\), approves or modifies them, and the graph resumes from the checkpoint. LangGraph implements this with interrupt\_before and interrupt\_after on nodes. Critical detail: show the human the exact arguments the agent is about to pass to the tool, not a summary. This lets them catch subtle errors like wrong recipient addresses or excessive quantities. Tradeoff: this adds latency for every interrupted action, so only interrupt on genuinely irreversible or high-stakes nodes, not every tool call. Over-interrupting causes approval fatigue and users start auto-approving.
