Creating nodes

Nodes are the executable units inside an agent tree.

In the editor

Create a tree, add a root node, then add children or specialist handoffs. Set:

• a clear name and capability;
• model and AI connection;
• business and execution prompts;
• timeout, retry, and output policies;
• connector bindings where external data is required.

From Python

import orchetree


@orchetree.node(
    tree="Research",
    capability="analysis",
    business_prompt="Compare the supplied evidence.",
    execution_prompt="Return claims with supporting sources.",
)
def analyse(inputs: dict) -> dict:
    return inputs

Run orchetree sync to upsert the definition. Removing a decorated definition marks its SDK-managed resource inactive rather than hard-deleting it.

From Node.js

Node.js uses function wrapping rather than Python decorators:

import { node } from "orchetree";

function analyse(input: unknown) {
  return input;
}

node(
  {
    tree: "Research",
    capability: "analysis",
    business_prompt: "Compare the supplied evidence.",
  },
  analyse,
);
