Tools Reference Manual#
Tools provide extensible action capabilities that transform passive AI assistants into active systems capable of interacting with external services, performing computations, and executing custom business logic. They serve as the bridge between conversational AI interfaces and operational systems within organizational infrastructure.
Architectural Purpose#
Tools extend language model capabilities beyond text generation by providing structured interfaces for external system integration. They enable assistants to perform concrete actions including data retrieval, system operations, and workflow automation while maintaining security boundaries and operational governance.
System Integration Framework#
Gen AI Builder Components
Assistants: Invoke tools through language model decision-making processes
Structures: Incorporate tools as workflow components within pipeline operations
Rulesets: Define tool usage policies and operational constraints
Memory Systems: Maintain context for multi-step tool execution sequences
External System Connectivity
APIs: RESTful and GraphQL service integration for data exchange
Databases: Direct database connectivity for operational data access
Services: Internal system integration through authenticated connections
Workflows: Business process automation through multi-tool orchestration
Technical Architecture#
Tool Implementation Framework#
Tools implement standardized interfaces that enable consistent integration across different assistant types and operational contexts. The framework supports both simple single-purpose tools and complex multi-step workflow automation.
Implementation Reference Tools are developed using the pgai-ai-builder SDK framework available at EnterpriseDB/pgai-ai-builder . This SDK provides the foundational classes and utilities for tool development.
Execution Architecture#
Tool Invocation Flow
Decision Phase: Language models determine tool necessity based on conversation context
Parameter Extraction: Relevant information extraction from user inputs and conversation history
Security Validation: Permission verification and rate limit enforcement
Execution Phase: Tool-specific logic execution with error handling and timeout management
Result Integration: Output formatting and incorporation into conversation flow
Context Updates: Memory system updates reflecting tool execution results
