Spec-Driven Development saved my sanity. I wasted weeks asking LLMs to generate code immediately—constant refactors, context doom loops, implementations that missed requirements. Now I make them explain the problem, propose approaches, debate solutions, THEN write specs before touching code. Planning precedes coding.

Airbnb's 99% LLM-generated code claim only works with this discipline. The kicker? Advanced models like Opus 4.6 follow instructions better, but only if you give them architecture docs and coding standards first.
