# Node Library

> Add Start, Agent, Child Agent, Tool, and End nodes to the canvas.

## Available nodes

* **Start**: entry point for the Agent Graph
* **Master Agent (Task)**: primary agent with prompt, tools, RAG, and variables
* **Child Agent**: reusable/embedded agent node
* **Tool (API)**: calls external tools or APIs
* **Sub-Agent Graph (optional)**: reference another Agent Graph
* **End**: terminates the graph

<Info>
  Node types correspond to React components in `src/components/nodes/` and are created with defaults via `createNode` in `src/utils/nodeUtils.ts`.

## Adding nodes

* Drag nodes from the library onto the canvas.
* Place near existing nodes to keep edges readable.
* Use consistent naming in the Inspector to aid collaboration.
