AI Agent : Google calendar assistant using OpenAI

## Tools Agent - Calendar AI Agent

This **node** configures the **AI agent** for interaction with Google Calendar. 
It includes the following features:

- A **prompt source**: This is the user message derived from the chat input of the preceding node (`When chat message is received`).
- A **system message**: This defines the system prompt to guide the AI agent's behavior. It incorporates the variable `{{ DateTime.local().toFormat('cccc d LLLL yyyy') }`, allowing the AI agent to determine the current date and interact with Google Calendar accordingly. For example, the agent can understand a request like "Create an event called 'n8n workflow review' for next Tuesday."


n8n nodes come with built-in **guardrails**, ensuring that if the user requests tasks outside the AI agent's setup, it may not function as intended. (Feel free to test it!)
