Mutations change data inside a transaction. Picture it like this: Signing one form that updates several records atomically. In the apps you ship (Agentify, wedding portals, CRM), you will bump into this on almost every screen — name it clearly when you prompt your coding agent.

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

Mutations change data inside a transaction. Signing one form that updates several records atomically. Ask yourself: where does this live in the database, which function changes it, and which screen shows it?
