The Vibe Coding Trap: Why Fast Development Becomes Slow Shipping

This case study reveals why AI-generated code without upfront specification leads to compounding bugs. While vibe coding appears fast (10 minutes to ship), it lacks designed invariants, idempotency checks, and concurrency safeguards, resulting in weeks of fixes. It challenges the assumption that AI eliminates the need for planning—instead, rigorous specification becomes more critical than ever.
