Write plain-English descriptions for n8n workflows

You run this by hand. It searches an Airtable table for records whose description field is empty, then loops through them one at a time.

For each record it downloads the n8n workflow file attached in the json_file field and sends the workflow's name and nodes to a Gemini model through an OpenAI-compatible connection. The prompt asks for a purpose and a step-by-step breakdown written for a non-technical reader, returned as JSON. The workflow writes both into the record's description field and moves on until every empty row is filled.
