Stop Vibe Coding: How Amazon Drives AI Code Generation with Specs
blaizedsouza · x · 2026-08-01
The thread critiques the casual approach of "Vibe Coding" and details how tech giants like Amazon use rigorous specification documents to drive high-quality AI code generation. In Amazon's workflow, the spec is not a throwaway planning doc, but the core artifact reviewed by the team.
Key steps in this engineering loop include:
- Requirement Generation: An initial prompt generates structured requirements with acceptance criteria using EARS syntax (when/then/shall).
- Automated Verification: Instead of another model call, classic automated reasoning scans the spec to detect ambiguity and resolve logical conflicts.
- Property Testing: Requirements are translated into correctness properties (invariants), which test cases then try to falsify. Only code passing these tests is accepted.
