Human-in-the-Loop Approval Gates

Claude (inside n8n)Automation From a course

The highest-trust automations pause for approval at the moments that matter: before sending externally, before spending money, before deleting anything.

The prompt

Draft the approval message for this automated action. Include: what will happen, to whom, the exact content being sent, and two options: APPROVE / EDIT. Keep it under 80 words so it's readable in Slack.

Action: {{$json.action}}

What to replace

Swap these placeholders for your own details before running the prompt:

  • {{$json.action}}your own value

Pro tip: Gate by risk, not by step count — auto-send internal digests freely, but gate anything customer-facing.

How to use this prompt

  1. Copy the prompt using the button above.
  2. Replace {{$json.action}} with your own details — the more specific you are, the better the output.
  3. Paste it into Claude (inside n8n) and run it.
  4. If the answer feels generic, add constraints: audience, length, tone, and what to avoid. That single change fixes most weak output.
