Two directions of integration
An external application can call an agent through a Smart Mind endpoint. Separately, an agent can invoke an action exposed through the Service Repository. The first brings work into the agent; the second gives the agent a capability to carry it out.
Design around a concrete exchange
A useful integration starts with a specific request and a clear expected result: the context sent, the identity and permissions involved, how the response is handled, and how errors and incomplete inputs are treated. These are agreed per project.
