harness

Executable protocol enabling any agent task to run continuously across multiple sessions with automatic progress recovery, task dependency resolution, failure rollback, and standardized error handling.

Free-text log of all agent actions across sessions. Never truncate.

Task statuses: pending → inprogress (transient, set only during active execution) → completed or failed. A task found as inprogress at session start means the previous session was interrupted — handle via Context Window Recovery Protocol.

此技能应用于需要进度检查点、故障恢复和任务依赖性管理的多会话自主代理工作。在“/harness”命令上触发，或者当任务涉及许多需要进度持久性的子任务、跨上下文窗口的睡眠/恢复周期、从具有部分状态的中间任务故障中恢复或跨多个代理会话的分布式工作时触发。由长期运行代理的 Anthropic 和 OpenAI 工程实践综合而成。 来源：cexll/myclaude。
