n8n Agent Node

⚠️ NOTICE: This node is not intended for public use and there is no support provided.

Overview

This n8n node provides a specialized agent integration for processing and structuring data according to a predefined schema. The node accepts input data and returns structured output that conforms to a hard-coded JSON schema format.

Usage

If you understand the node's functionality and can work with its current implementation, you are welcome to use it as-is. Please note that:

- The output schema is hard-coded and cannot be modified through the node interface
- No documentation or support is provided beyond this README
- The node is designed for specific internal use cases

Output Schema

The node returns structured data according to the following hard-coded JSON schema:
