TypeScript checks shapes
TS verifies values match the shape you declared.
Difficulty 2/5
Short
Plain English
TS verifies values match the shape you declared. Picture it like this: A jigsaw piece either fits or it doesn't. 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.
Analogy

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
TS verifies values match the shape you declared. A jigsaw piece either fits or it doesn't. Ask yourself: where does this live in the database, which function changes it, and which screen shows it?
