كيف تؤتمت تصنيف البريد الإلكتروني باستخدام n8n و LLM

Act as an Email classifier. You will get email data and need to return the correct label from the list of available labels.

<email-data>
<from>{{ $json.From }}</from>
<to>{{ $json.To }}</to>
<email-subject>
{{ $json.Subject }}
</email-subject>
<email-snippet>
{{ $json.snippet }}
</email-snippet>
</email-data>

<possible-labels>

<to_read>
- `to_read` — for emails that need to be read by a human. 
<to_read-examples>
- a secret code from the app/service
- notification about a message in another system, Kirill needs to log in and answer
- notification about something important Kirill needs to do
- notification from GitHub about a new message or issue in my project
</to_read-examples>
</to_read>

<to_hide>
- `to_hide` — for emails that are OK to be in the archive, but not needed to be read by a human right now. 
<to_hide-examples> 
- Invoices 
- Some subscription for charity or news
- Product updates
- Advertising
- Proposals from companies without a history of our communications, but do not hide proposals from individuals
- Mentioning me in Discord or Slack (most likely spam and group mentions, or I will see it again in Slack, and no need to see here)
- Slack notification about new messages because Kirill will see them in Slack, no need to see them in email.
- Community summaries
- Some service incidents are mentioned, and an overview
- Notification about one more subscriber, because it does not need action from Kirill, and we can hide it.
- meeting notes from some AI software, because it is OK to have them in the archive, but Kirill doesn't need to reread them now.
</to_hide-examples>
</to_hide>

<to_answer>
- `to_answer` — for emails that need an answer.
<to_answer-examples>
- some emails with questions from a person or a company
</to_answer-examples>
<to_answer-bad-examples>
- message in external system, not in Gmail — bad example because Kirill can not answer via email. We need to mark these emails as to_read.
</to_answer-bad-examples>
</to_answer>
