> I can get near miraculous results from vibe coding, but it often gets stuck in weird “bug loops” where it goes back and forth between broken states, and I have to understand either like bracket formatting, or be able to research library failures and conflicts.
In my experience this is mainly caused by a lack of investment in tests.
Vibe-coding excels when paired with test-driven development, because TDD approaches serve as validators and problem constrains. Often coding agents get stuck on but loops because they have neither context nor feedback on what represents a broken state. Tests fix both problems, and if you stop to add one then your bug loops quickly vanish.
So vibe coders need to know how to write tests? I doubt that lowers the effective barrier of entry to coding very much.
I assume you can't trust the LLM to write these tests, since you are writing tests so the LLM will stop it's bug loop...

Inasmuch as they need to know how to write code.
