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.
