A Platform Administrator needs to create a new prompt template to automatically summarize customer cases...

When building prompt templates within the Prompt Builder, the most direct way to inject specific record data into the AI ' s instructions is through Merge Fields. Much like an email template or a mail merge, merge fields allow the administrator to reference specific fields from the object in context—in this case, the Case object. For example, an administrator might use {!$Input:Case.Subject} or {!$Input:Case.Description} within the prompt template. When the agent runs, it replaces these placeholders with the actual data from the specific case record being viewed. This ensures that the AI has the " grounding " information it needs to generate an accurate and relevant summary. While Flows (Option A) can be used for more complex data retrieval, Merge Fields are the standard, low-code tool for simple record-to-prompt data population. Agent Instructions (Option C) provide the " how-to " logic for the AI but do not themselves represent the dynamic data points from the Salesforce database.
