AI review agents are excellent first pass tools. They are not auditors.
What agents catch well
- Obvious SQL/escaping issues in PHP templates
- Missing
esc_html/esc_urlin WordPress output - Dead code and inconsistent naming
What humans must still check
- Authentication and capability checks
- Form spam and rate limits
- Cookie/consent interactions
- Business logic regressions (pricing, CTAs)
Pre-merge checklist
- Agent review comment addressed or rejected with reason
- PHP lint + staging click-through on mobile
- No secrets in diff
- Rank Math / schema unchanged unless intended
