Question

Leadership wants your REST API migrated to GraphQL and suggests pointing an AI agent at the OpenAPI spec to 'generate the whole schema and resolvers.' You have 80 endpoints, real production traffic, and downstream mobile clients on old app versions. How do you scope this for the agent and sequence the migration so nothing breaks?

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.

Describe your solution

Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.

Run or narrate your approach, then ask the coach.
