The review problem

Most vibe coders review AI code the same way they review their own: skim for obvious problems, check if it works in dev, ship. This is fine for low-stakes features. It's dangerous for auth, payments, and data handling.

The 3-layer review framework

Layer 1: Does it work? (functional review) — Layer 2: Is it safe? (security review) — Layer 3: Will it hold up? (resilience review). Most reviews only do Layer 1.

Layer 1: Functional review (2 minutes)

Does the happy path work? Does the error path do something reasonable? Are there obvious logic errors? This is what you're already doing.

Layer 2: Security review (3 minutes)

Check for:

  • Any string interpolation in database queries → SQL injection risk
  • Any user input rendered as HTML → XSS risk
  • Any secrets in the code → exposure risk
  • Auth checks on all protected operations
  • CORS and rate limiting on public endpoints

Layer 3: Resilience review (2 minutes)

Check for:

  • try/catch on all async operations
  • What happens when the external API is down?
  • What happens with unexpected input types?
  • Any infinite loops or unbounded operations?

The post-ship review

After shipping, watch your error monitoring for 30 minutes. ProdFix will surface any issues immediately with full context. This is your last line of defense — and often catches things that even careful manual review misses.

Stop flying blind in production.

ProdFix gives you error monitoring, performance tracking, security alerts, and AI-powered fixes — built for solo founders and vibe coders. One SDK, 2-minute setup.
