What the exam expects

  • Choose a standard subagent or action before building a custom one.
  • Pick the reference action type (flow, Apex, prompt template, external service, MuleSoft API) for a custom action from the requirement.
  • Configure action instructions and input and output settings: Collect data from user, Require input, Show in conversation, Require user confirmation.
  • Explain the Agentforce Assets copy model and keep subagents focused.
  • Change a live agent safely with versions and activation.
  • Key terms: subagent (formerly topic: a job the agent can do, with instructions and actions); standard asset (a Salesforce-provided subagent or action in the asset library); custom action (an agent action you build on a reference action); reference action (the flow, Apex, prompt template or API the action calls); agent version (an editable draft until activated).
