Power Up Your AI with the MerchantFlow Skill File
Download the MerchantFlow Skill file and install it in Claude, Cursor, or Windsurf for dramatically better answer quality from your AI assistant.
The MerchantFlow Skill File
The MerchantFlow Skill file is an optional download that teaches your AI assistant how to think about ecommerce data, which tool to pick for each question, and how to format answers. It's the v1 MerchantFlow differentiator - most MCP servers just ship tools and hope the AI figures things out; we ship curated guidance so your assistant speaks ecommerce fluently from day one.
What's in it?
- Identity primer - teaches the AI its role as a financial co-pilot
- Mental model - the ecommerce P&L waterfall and key metric definitions (MER, contribution margin, payback period, SDE multiple)
- Tool selection cheatsheet - which tool to pick for each type of question
- 20+ question-to-tool routing examples - few-shot examples that dramatically improve tool-calling accuracy
- Anti-patterns - things the AI should never do (like computing margins from revenue breakdowns, or repeatedly polling the same tool)
- Output style guide - formatting rules that match what DTC operators actually want to read
- Privacy reminders - PII handling rules
Before and after
Without the skill file, ask "how are my ads doing?" and you'll get a generic response like: "Let me check your ad performance. Your Meta ads spent $X with Y clicks..."
With the skill file: "Your blended MER dropped from 3.2 to 2.7 this week - down 15%. The driver is Meta (MER fell from 4.1 to 2.8 after your new UGC creative launched Tuesday). Google is flat at 2.9. Recommendation: pause the Tuesday creative test and compare the next 48 hours of MER to decide whether to kill it permanently."
Same data, same tools, dramatically better answer.
