The correct answer isA— in UiPath’s Agent Builder (Studio Web), when you add atool(e.g., Integration Service activity, process, API call), it's essential to include aclear description and usage instructions. This description serves as aguide for the LLM, helping it understand:
Agents rely on this metadata todecidewhen and how to call the tool appropriately during execution. For example, if a tool is meant to send a Slack message, the description should say:
“Use this tool to notify the support team when a high-priority ticket is detected.”
Without a clear tool description, agents may:
Misuse tools (e.g., calling the wrong one)
Fail to act when they should
Deliver inconsistent results due to lack of grounding
Option B is incorrect — tool access doesn’t grant unrestricted data privileges.
C is too narrow — the prompt alone doesn’t restrict reasoning; the tool description plays a key role.
D is false — tool execution depends on agent reasoning and prompt logic, not automatic access.
Adding focused usage guidance ensuressafe, relevant, and accurate tool invocation, which is essential in agentic workflows that combine LLM flexibility with enterprise-grade precision.
