Code review trifecta

Diff digest → security pass → test ideas → architecture doodle

Triage a 1,200-line PR before standup

4-column Gab AI Deck recipe for engineering teams

Code Review Trifecta is the deck senior engineers reach for when the PR queue is brutal. Column 1 summarises the diff into reviewer-friendly language; column 2 runs a security and quality pass; column 3 proposes test cases the author may have missed; column 4 sketches the architectural change as a diagram. The deck does not approve PRs — that is still on humans — but it gives reviewers the ammunition to leave the right comment on the right line.

How to use this recipe

  1. Click "Use this recipe" to clone the 4-column deck.
  2. Paste the diff or PR URL into column 1 — let the model summarise the intent before security pass starts.
  3. Run security pass and test plan in parallel; the security column flags risk, the tests column proposes coverage.
  4. Use the architecture doodle for any PR that touches more than two files; it surfaces the structural change.
  5. Drop the structured output as PR review comments; engineering owns the final approve/request-changes call.

Code Review Trifecta FAQ

Does this replace human code review?

No. It accelerates the human reviewer's context-loading and surfaces issues they may have missed. The approval, the design judgment, and the final call still belong to a person.

Will it catch all security issues?

No. AI security passes catch a subset of common patterns (injection, auth bypass, secrets in code) but miss novel and business-logic vulnerabilities. Run alongside SAST tooling and security-team review.

Can it review my private codebase?

You control what you paste. For sensitive code, follow your organisation's policy on third-party AI tooling. Gab AI does not train on your inputs by default.

How long can the diff be?

Up to roughly 5,000 lines of unified diff per column. For larger PRs, split by file or by feature surface — that is also better human review practice.

Will the test plan run the tests?

No — it proposes test cases in your test framework's syntax. Engineering implements and runs them in CI.
