UnverifiedAfter being wrapped via MCP, the Agent can autonomously decide the next action based on the actual state of the page, for example determining the button position based on the DOM structure and executing the click only after the element appears; this "plan-act-observe" loop is the essence of what distinguishes an Agent from a script.72% similarUnverifiedFor computer-use Agents, indirect prompt injection is especially dangerous because the Agent possesses real operational permissions.72% similarVerifiedWhen authorizing an Agent to perform high-risk operations, a manual confirmation step should be established, where the Agent proposes the plan and humans retain final execution authority (human-in-the-loop mechanism).71% similarUnverifiedAgent的行为路径是概率性的，不同于按钮点击后的确定性响应，对交互设计的容错、状态反馈和用户预期管理提出新挑战71% similarUnverifiedPrompt engineering for production-grade Agents requires adding constraints, otherwise the Agent may perform sensitive operations (such as sending emails) without approval.71% similar
