Jediah splits the harness into the runtime layer (controlling where the agent runs, loop execution, state storage to support task recovery) and the context and orchestration layer (deciding when to call which model and what context the model sees, including prompts, tools, memory, compaction and other mechanisms).

UnverifiedJediah lists three categories of harness components that models cannot absorb: infrastructure and runtime (agent tasks extending to hours or days require moving to the cloud), trust and safety (narrowing permissions and guardrails to prevent catastrophic operations or large API bills), and efficiency (studies all find significant differences in cost per task).75% similarUnverifiedJediah proposed the concept of a "data flywheel": the harness makes increasingly difficult coding tasks accessible, more users use agents to attempt these tasks, more coding data is shared with the labs, and once models natively learn these skills, the harness can delete what was originally added to make the tasks work.73% similarUnverifiedHarness introduces a persistent state machine that tracks Agent task stages and passes structured context snapshots rather than full conversation histories, reducing token consumption and hallucinations.60% similarUnverified全双工的委派机制是一种异步推理卸载架构，将计算密集型任务异步分发给后台模型，类似任务队列模式60% similar
