Question
You're building a YAML config parser in Rust for a CLI tool: load a `config.yaml`, validate it against a schema, apply defaults, and surface clear errors with the offending field path and line. You'll delegate it to an AI agent. Write the prompt/spec — constraints, edge cases, acceptance criteria — for a first-try-correct result. What does a vague prompt ("parse the YAML config") get wrong in Rust specifically?
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.
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.
