How Much Authority Should Agents and Developers Have in Controlling Profitable Promotional Content?

If agents start to frequently recommend paid tools, services, APIs, or SaaS products, a design issue becomes particularly important: Who controls the recommendation interface? I believe that most developers do not want to directly embed such "black box" advertising plugins into their applications. But a completely customized control method might make the attribution, reporting, and standardization of advertisements extremely difficult. So perhaps the real question is what control measures should be set as default. For example, should agents and developers be able to decide: \- What categories are allowed \- Which suppliers are to be blocked \- What the frequency of recommendations should be \- Whether multiple options must be displayed \- Whether reasons need to be explained \- Whether paid rankings are allowed \- Whether the source and revenue data can be seen \- Whether the recommendation function can be turned off by users If the control is too weak, then this agent will start to feel like someone else's advertisement. If the control is too strong, then this ecosystem may never achieve compatibility. I'm curious where the boundaries will be set by these construction workers. Before integrating paid recommendation functions into the agency system, what control measures will you need? And what situations will make you reject immediately?
