Node

As you have seen in agents, each item within the workflow paramter represents an instance of a Node class.

There are 3 types of Node currently available:

• prompt
• mcp
• return

PromptNode

Represents a single step within the prompt chain. This node is designed for text llms.

class PromptNode extends Node {
    type             enum
    name             String

    system           String
    user             String

    apikey           String
    llm              enum
    model            String
    temperature      int
    maxTokens        int

    output           String
}

type (String, enum)
Represents the type of node. This is used for determined casting in downstream nodes

name (String)
the name of this node. Used for logging purposes

system (string)
Represents the system prompt. This string accepts a special templating synthx using {field}. This is substituded in workflow runtime by referring to values stored in variables within agent.

user (string)
Represents the user prompt. This string accepts a special templating synthax using {field}. This is substituded in workflow runtime by referring to values stored in variables within agent.

apiKey (String)
The API key for this prompt node. This string accepts a special templating syntax using {field} which will allow the API key to be parsed at workflow runtime from agent.variables

llm (String, enum)
