Support high-DPI retina displays
SkillMediaretina-display is a skill for AI agents that reviews image assets, markup, and CDN or build transforms related to Support high-DPI retina displays. It checks encoded size, rendered size, loading strategy, and above-the-fold impact together, so images and page code look sharp on high-resolution screens.
Available today. Use it from your connected AI after setup.
No other account needed.
Have an AI agent that can load skills.
Then ask your AI: use the Support high-DPI retina displays skill
What your AI can do with it
- Review image assets for retina display readiness
- Check markup related to high-DPI rendering
- Evaluate CDN or build transforms affecting images
- Check encoded size of image assets
- Check rendered size of image assets
- Assess loading strategy and above-the-fold impact together
Getting started
- Have an AI agent that can load skills.
- Add the retina-display skill to the agent's available skills.
- Ask the agent to review your image assets, markup, or CDN and build transforms for retina display support.
What this skill tells your AI
The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/retina-display/SKILL.md and read by ahel’s review.
Standard images look blurry on retina displays (2x, 3x pixel density)—high-resolution assets ensure sharp visuals on modern devices.
Quick Reference
- Provide 2x and 3x images for high-DPI displays
- Use srcset with x descriptors for fixed-size images
- Use srcset with w descriptors for responsive images
- CSS background-image: use image-set() or media queries
Check
Check if high-resolution images are provided for retina displays (2x, 3x).
Fix
Add retina-ready images using srcset or CSS image-set for high-DPI displays.
Explain
Explain how retina images ensure sharp visuals on high-density displays.
