According to the AgentForce Action Design and Configuration Guide, action instructions serve as the directive text that informs the Reasoning Engine about when and how to invoke a specific action. The documentation states: “Action instructions guide the reasoning engine by describing the action’s purpose, inputs, and when it should be selected. Clear, concise instructions improve the LLM’s accuracy in mapping user intent to the correct action.”

Option A is correct because it reflects this documented purpose — connecting user intent with the appropriate system action.

Option B is incorrect since the temperature parameter for the LLM is defined at the system or configuration level, not within action instructions.

Option C is incorrect because action instructions are meant for the reasoning engine, not for end users.
