Persist agent state across crashes, context deaths, and restarts. Use when you need to save current context, restore after a crash, maintain a memory file across sessions, or implement crash recovery. Essential for autonomous agents that must survive context window limits.

在崩溃、上下文死亡和重启时持久化代理状态。适用于需要保存当前上下文、崩溃后恢复、跨会话维持内存文件或实现崩溃恢复的场景。对于必须突破上下文窗口限制的自主代理至关重要。
