When building human-in-the-loop (HITL) agent systems, the request side can block most spam requests through an llms.txt endpoint with proof of work (PoW), but the reply side is the truly tricky part.

UnverifiedIn general software scenarios for LLM Agents, mechanically copying HITL (human-in-the-loop) mechanisms has the problem of a risk model mismatch: most software failures are retractable, retryable and traceable, whereas the cost of HITL falls genuinely on human attention.75% similarVerifiedHITL（Human-in-the-Loop，人机协同）概念源于自动化控制领域，用于在 Agent 遇到高风险、高不确定性操作时进行人工审核确认69% similarUnverifiedThe handwritten agent approach essentially involves directly calling the LLM API and managing the tool-calling loop manually, typically implemented as an explicit while loop that checks tool_calls and appends results to a message list.65% similarUnverifiedAn agent's behavioral path is generated in real time by the LLM, and the same user request may produce entirely different tool-call sequences, making it difficult for static permission configurations to cover all scenarios.65% similarUnverified智能代理层工作在应用层（L7），能够解析HTTP请求的完整语义（目标域名、请求路径、请求体内容），实现基于业务逻辑的细粒度控制65% similar
