SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

The ax-provider-eventbus Skill Unit provides a solution for managing real-time, typed pub/sub events within the AX personal AI agent ecosystem, facilitating efficient communication between components.

Core Features & Use Cases

  • Real-time Pub/Sub: Enables real-time event distribution and subscription within the AX system.
  • In-process and PostgreSQL Support: Abstracts communication between in-process and PostgreSQL, facilitating k8s deployment.
  • Event Handling: Components can emit StreamEvents, and listeners can subscribe globally or per-request.
  • Use Case: For instance, when you need to trigger actions based on specific events within the AX framework, the event bus can be used to efficiently manage these triggers.

Quick Start

To emit an event, use the emit method on the EventBusProvider. Example: eventBus.emit(new StreamEvent('type', 'data')).

FAQPage Schema
How do I manage real-time event communication in an AI agent framework?▼

Real-time event communication in an AI agent framework is managed through a pub/sub event bus that supports emitting typed StreamEvents and subscribing listeners globally or per-request for efficient component interaction.

Does the event bus support PostgreSQL pub/sub for k8s deployment?▼

Yes, the event bus supports PostgreSQL pub/sub alongside in-process communication, abstracting the transport layer to facilitate scalable Kubernetes deployments across multiple agent instances.

How do I emit an event to trigger actions in an event-driven AI architecture?▼

To emit an event in an event-driven AI architecture, call the emit method on the EventBusProvider with a new StreamEvent object containing the event type and data payload, distributing it to subscribed listeners.

What is the difference between global and per-request event listeners in a system architecture?▼

Global event listeners subscribe to all events across the system architecture, while per-request listeners are scoped to individual requests, ensuring isolated event handling for specific AI agent interactions.

When do I need a typed pub/sub event bus for AI agent components?▼

A typed pub/sub event bus is needed when AI agent components must react to specific triggers in real-time, requiring structured StreamEvent distribution and subscription without direct component coupling.

Can I use in-process pub/sub for real-time communication without a database?▼

Yes, in-process pub/sub is supported for real-time communication without requiring a database, enabling efficient event distribution within a single process while PostgreSQL is available for distributed scenarios.
