Bis correct — in UiPath’s agent framework,guardrailsplay a critical role incontrolling tool behavior and decision outcomesduring agent execution. Specifically, guardrails enable developers tohandle edge cases and define conditionsunder which:
The agent shouldescalate to a human
A tool should be skipped, modified, or retried
Output should be checked against validation rules
Guardrails workdeterministically, meaning they arerule-based conditionsapplied before, during, or after a tool runs — depending on the configuration. This allows for predictable and governed responses, such as:
“If tool output confidence is below 70%, escalate the task to Action Center.”
Option A is incorrect because guardrailscan and often do trigger human intervention.
Option C is false — guardrails can influencepre-execution, such as preventing tool calls under certain input conditions.
Option D downplays runtime functionality — guardrails are especially powerful during execution to protect against invalid results, failed API calls, or LLM drift.
UiPath promotes the use ofguardrailsto ensuresafe, accurate, and context-aware agent behavior, especially in regulated or sensitive environments.
