A Zero-to-One AI Coding SOP: From One Sentence to Verifiable Delivery

Don't just tell AI to write code — clarify, propose, plan, execute in stages, and prove correctness with tests

  • AI-Coding
  • SOP

The one-sentence method

Don’t just tell AI to write code. Clarify requirements first, then propose a solution, write a plan, execute in stages, and finally prove the result correct with tests and acceptance criteria.

Why not just tell AI to write

Handing a task to AI in one sentence produces code that “looks right”: no requirement clarification, so boundaries are guessed; no proposal review, so architecture is arbitrary; no acceptance criteria, so correctness is unprovable. Processed input buys verifiable output.

The five-step SOP

  1. Clarify: pin down vague requirements, define boundaries and success criteria
  2. Propose: have AI present 2-3 approaches with trade-offs, then write the design
  3. Plan: decompose the design into independently verifiable tasks, each with tests
  4. Execute in stages: one task at a time, verifying each step
  5. Accept: prove correctness with tests and acceptance criteria — not “looks fine”

The experiment framework

The value of this SOP can be validated with a controlled experiment: the same task, one group “hands it to AI in one sentence”, the other “feeds it through the SOP” — compare completion time, rework count and acceptance rate. The goal is a process that can be promoted within a team, backed by data.

Lessons from practice

  • Time spent clarifying is repaid tenfold during execution
  • If you cannot write acceptance criteria, you have not thought the requirements through
  • An SOP is not a constraint — it turns luck into predictability
