Add Guardrails Models

Summary

Implements a comprehensive guardrails system for UiPath agents with configurable validation rules and actions.

Changes

Guardrails Models (src/uipath/models/guardrails.py)

Core Components

• Field Selectors: AllFieldsSelector, SpecificFieldsSelector with discriminated unions
• Validation Rules:
  • WordRule - Text validation with operators (contains, equals, startsWith, etc.)
  • NumberRule - Numeric validation with comparison operators
  • BooleanRule - Boolean field validation
  • UniversalRule - Always-apply rules for input/output/both
• Actions:
  • BlockAction - Stop execution with reason
  • FilterAction - Remove specific fields
  • LogAction - Log events with severity levels
  • EscalateAction - Human-in-the-loop workflows
• Guardrail Types:
  • CustomGuardrail - User-defined rules and logic
  • BuiltInValidatorGuardrail - Pre-built validators with parameters

Agent Integration (src/uipath/agent/models/agent.py)

• Added guardrails: Optional[List[Guardrail]] to BaseAgentDefinition

Testing and Example Usage (tests/agent/models/test_agent.py)

• JSON parsing validation for complex guardrail configurations : test_agent_config_loads_guardrails
