Core Concepts
Overview
AI Services within xBot are the fundamental building blocks that enable intelligent automation and conversational experiences. These services work cohesively by passing information through a defined execution state, creating powerful workflows that can handle complex business processes with AI-driven decision-making capabilities.
How AI Services Connect with Each Other
AI Services are designed to work together seamlessly through a sophisticated data flow mechanism:
Service Chaining
The output of one service is incorporated into the AI Flow execution state, which then serves as the input for the next service in the sequence. This creates a chain of intelligent operations that build upon each other's results.
Execution State Management
The AI Flow execution state acts as a dynamic data structure that captures all relevant information as the flow progresses. Each service's output is merged back into this state, ensuring that all subsequent services have access to the most up-to-date data and context.
Context Preservation
By continuously updating the execution state, xBot ensures that each service operates with a full understanding of the context, enabling accurate and context-aware processing of user queries and tasks.
This mechanism allows xBot to maintain a consistent and coherent flow of data across all AI services, ensuring efficient and reliable operations.
Common Configuration
All AI services share common configuration patterns that ensure consistency and smooth integration within AI Flows:
Default Transition
Transition Mechanism: AI services are chained together by transitions that can be defined by specific conditions determining the next service to execute
Fallback Transition: If none of the specified conditions are met, the default transition will be taken, ensuring the AI Flow continues to progress
Flow Termination: Transitions can either lead to another service or specify that the current service is the end of the AI Flow
Output Answering
Response Configuration: Specifies whether a response message should be sent to the end user during the current conversation
Content Specification: The content of the response message is defined by the
answerMessageexpression, allowing contextually appropriate responses based on the data within the AI Flow execution state
User Message & System Message
System Message: Sets the context for the AI agent, acting as a guideline that instructs the AI on how to behave and what role to assume during interactions
User Message: Represents the input from the user that the AI service needs to process, dynamically constructed based on user interactions
