Diff self-review: make the AI explain its own change before you accept it

The AI changed five files and you're about to click accept. Make it review its own diff like a skeptical outsider first.

The prompt — copy and run it

You are a skeptical staff engineer reviewing a code change — and the twist is that YOU (the AI) may have written it. Review it as if a stranger submitted it. I will paste the diff or the before/after. Produce:

A) PLAIN-ENGLISH CHANGELOG — what actually changed, file by file, in language a non-engineer can check against their intent: 'the save button now also…' not 'refactored the handler'.

B) INTENT MATCH — my stated request vs what the change actually does: anything I asked for that's missing, and anything the change does that I did NOT ask for (renames, deletions, new dependencies, changed defaults) — each flagged.

C) RISK SCAN — the 2-3 likeliest ways this change breaks something that worked yesterday, each with the 30-second manual check to catch it.

D) ACCEPT / REJECT / ASK — a verdict: accept as-is, accept after the checks in C, or reject with the smaller change to request instead.

Inputs: [WHAT I ASKED FOR] · [PASTE THE DIFF OR BEFORE/AFTER FILES] · [WHAT WAS WORKING BEFORE THAT MUST KEEP WORKING]

Rules: Do not invent code or behavior not visible in the paste — if the change references files I didn't include, name them and ask. Unrequested changes are findings, not features: flag every one, even if they look like improvements. Never approve your own work on trust — the verdict must rest on the checks in C, which I will run and verify myself. Keep secrets and credentials out of the changelog.

How to use this prompt

  1. Copy the full prompt above with the Copy button.
  2. Fill in your inputs. Replace each bracketed placeholder with your specifics: [WHAT I ASKED FOR][PASTE THE DIFF OR BEFORE/AFTER FILES][WHAT WAS WORKING BEFORE THAT MUST KEEP WORKING]
  3. Paste into ChatGPT, Claude, or Gemini and run. Read the reality guardrail below before you act on the output.

Why this prompt works

Accepting multi-file AI changes on faith is how working apps quietly rot. Forcing a plain-English changelog against stated intent surfaces the unrequested 'improvements' that cause mystery breakage, and the run-it-yourself verdict keeps the human as the actual approver rather than a rubber stamp.

Frequently asked

When should I use this prompt?

The AI changed five files and you're about to click accept. Make it review its own diff like a skeptical outsider first.

Why does this prompt work?

Accepting multi-file AI changes on faith is how working apps quietly rot. Forcing a plain-English changelog against stated intent surfaces the unrequested 'improvements' that cause mystery breakage, and the run-it-yourself verdict keeps the human as the actual approver rather than a rubber stamp.

What mistake does this prompt help you avoid?

The unrequested change nobody noticed — every deviation from stated intent is flagged as a finding, and acceptance rests on checks the human runs, not the model's say-so.
