The prompt

Paste a prompt into your AI tool. Each one points the tool at the docs and at your key, which stays in BUILD_API_KEY.

Read https://build.sellermate.ai/SKILL.md. My key is in BUILD_API_KEY. Every morning, work out days of stock per SKU from my Amazon Seller stock and the last 30 days of orders, write the reorder date to a Google Sheet, and post a Slack message to #reorder for any SKU inside its 35 day lead time.

Stock-out ad protection

For n8n. Schedule: Every night at 2.

Prompt · n8n
Read https://build.sellermate.ai/SKILL.md. My key is in BUILD_API_KEY. Build me an n8n flow that every night checks stock for each SKU with live Amazon Ads, pauses ads when fewer than 5 days of stock are left, resumes them after a restock, and logs every change to the Google Sheet stock-log.
