Difficulty 2/5
Short
Plain English

Common mistakes
- Letting the AI rename this concept three different ways in one PR.
- Building UI before you can say what is stored and who can change it.
AI-agent trap
Agents may invent jargon here. Ask them to explain the concept in plain English first, then map it to your schema and one real screen.
Summary
Any system you don't control — Stripe, WhatsApp, Google. Suppliers outside your kitchen. Ask yourself: where does this live in the database, which function changes it, and which screen shows it?
