What this is

A real workflow someone ran with an AI agent. Copy the prompt into your agent, connect the listed tools, and it runs for you.

  1. Copy the prompt below.
  2. Paste it into your agent (we recommend Grok Bot) and connect the tools listed: whatever the prompt mentions.
  3. Run it once, check the result, then put it on a schedule if it repeats.
