The "Brain Sandwich": a three-step workflow for using AI without atrophying your engineering judgment
bibryam · x · 2026-10-29
A post on Terrible Software introduces the "Brain Sandwich," a simple framework an engineer named Emily uses to get full value from AI coding agents without removing her brain from the equation (a state engineers jokingly call being a "Meat Proxy") amid rising code-review loads.
The workflow has three layers:
- Brain first: before asking an agent to build anything, read and understand the problem yourself. You don't need a full plan, but without a rough direction AI can bias you wrong—or steer you into solving a problem you never had.
- AI in the middle: with that context, delegate the implementation shamelessly; you're now equipped to judge whether the solution is right, overengineered, or solving the wrong problem.
- Brain again at the end: before requesting review, read the diff, judge whether the complexity is worth it, and write a proper PR description. Rule of thumb: if you can't explain what changed and why, it's not ready.
The core claim: exploit AI's productivity fully while keeping your own engineering judgment from atrophying.
