Design QA for AI agents
Design QA for AI agents is the review layer that catches generic output before it ships. It should inspect hierarchy, spacing, typography, colour, responsiveness, accessibility, asset quality, trust claims and conversion clarity.
Screenshot review
Use screenshots at desktop and mobile widths. Ask the agent to identify hierarchy problems, cramped sections, weak alignment, awkward type scale and CTA confusion.
Source code review is not enough. Many design defects are only obvious in a rendered screenshot.
Adversarial critique
Do not ask the model to check the work. Ask it to review like a senior design critic and produce a ranked fix list.
The critique should name the issue, the affected section, the reason it matters and the concrete fix.
Trust checks
Look for fake logos, unsupported claims, generic testimonials, distorted mockups and stock-looking imagery.
AI-built pages often look finished while containing credibility problems. Trust checks make those visible.
Prompt example
Review this website screenshot like a senior product designer.
Find issues in hierarchy, spacing, type scale, colour, contrast, CTA clarity, asset quality, responsiveness and trust.
Prioritise anything that looks generic, fake, cramped, inaccessible or likely to reduce conversion.
Return a ranked list with exact fixes. Do not be polite. Be specific.Common mistakes
- Asking for vague feedback.
- Reviewing only the desktop screenshot.
- Ignoring fake claims and low-trust proof.
- Accepting tiny, low-contrast labels.
- Not rechecking after fixes.
Workflow
- Capture desktop and mobile screenshots.
- Run an adversarial critique prompt.
- Patch the top-ranked visual and trust issues.
- Re-run screenshots and link checks.
- Only then ship or hand off.
