Agent N8N not execute tools

Hey guys, I’ve been dealing with a bug in my N8N for 3 days that’s keeping me from sleeping.

Can someone help me?

1- Bug
The whole problem is in the tools configuration of my agent; no tools seem to execute. I tried Google Calendar to save appointments, and the AI would return that it had saved an event on the calendar, but nothing was saved.

I also tried sending emails, and that didn’t work. Regarding email sending, when I run the tools node passing the parameters that the AI provides, the email is sent, so the problem isn’t with the credentials.

2 - Functionality

My agent receives WhatsApp messages, and depending on the user’s message (if they want to schedule a consultation with a lawyer, ask questions, or check a case), my agent executes the tool.

3 - Workflow:

Hi @GUILHERME_SILVERIO ,

You need to provide clear description in tool, when to use this tool by AI Agent. And also mention in Prompt how to use this tool. So AI Agent can clear knowledge to call tool.

Thanks.
