Chain of thought workflow This workflow breaks down complex problems into steps: 1. Decompose problem into sub-problems 2. Solve each sub-problem seq

Multi-agent coordination strategy

Embedding model

Event trait - all events implement this

Event handler trait - defines how to handle specific event types

Plugin that intercepts events before and after handling (middleware). An `EventInterceptor` can observe or transform events at the boundary of the ev

Event router - registers and dispatches events to handlers

Plugin that provides event sources. An `EventSourcePlugin` introduces new event streams into the runtime. For example, an A2A connector plugin subscr

Execution context for workflows

Image generation model

Language model specialization

Long-lived runtime (e.g., OS processes, Cloudflare Workers) Runtime persists across multiple workflow executions

Core model trait - all AI models implement this

Model provider trait - provides access to different model types

Multi-agent workflow Coordinates multiple agents to solve complex tasks

Observable stream of events (sensors, environmental changes)

Permission system for secure resource access

Core plugin trait - all plugins implement this. A plugin represents a reusable extension that hooks into the agent lifecycle. Plugins are initialized

A runtime that supports plugins. Extends the base `Runtime` trait with plugin management. The runtime is responsible for driving the plugin lifecycle

A composable set of plugins with unified lifecycle management. `PluginSet` allows multiple plugins to be composed and their lifecycles managed togeth

ReAct (Reasoning + Acting) workflow This workflow alternates between reasoning and acting: 1. Reason about the current state 2. Decide on an action 3

Reflection workflow This workflow uses self-critique to improve outputs: 1. Generate initial response 2. Critique the response 3. Refine based on cri

Runtime abstraction

Task scheduler trait

Short-lived runtime (e.g., cloud functions, serverless) Runtime exists for single workflow execution with state restoration

Speech/Audio model

Stream trait for observable events

Platform-specific system interface

System effect - represents a side effect that modifies system state

Task handle for tracking scheduled tasks

Core tool trait - all tools implement this

Tool loop agent - repeatedly calls tools until goal is met This workflow: 1. Receives input from user 2. Uses language model to decide next action 3.

Plugin that provides tools to the agent. A `ToolPlugin` extends the agent's capabilities by making additional tools available. For example, an A2A co

Tool registry trait

Video generation model

Wrapper that adds a system prompt to a language model

Workflow trait - defines a unit of work that can be executed
