Keep page load time under 3 seconds

SkillMedia

page-load-time is a skill for AI agents that audits slow page loads, heavy assets, and rendering delays. It guides the agent to keep page load time under 3 seconds, verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes, and flag the specific files, requests, or rendering steps that add cost.

Available today. Use it from your connected AI after setup.

Have an AI agent that can load agent skills.

Then ask your AI: use the Keep page load time under 3 seconds skill

What your AI can do with it

  • Measures page load time and verifies it is under 3 seconds on a standard connection
  • Identifies the actual bottleneck using DevTools, Lighthouse, or field data
  • Reviews routes, assets, and loading behavior, flagging files, requests, or rendering steps
  • Recommends fixes such as lazy loading, CDN usage, caching strategies, and resource optimiz
  • Explains how page load time affects bounce rate, SEO rankings, and user satisfaction
  • Focuses on Core Web Vitals: LCP, FID/INP, and CLS, with testing on throttled 3G

Getting started

  1. Have an AI agent that can load agent skills.
  2. Add the page-load-time skill to the agent's available skills.
  3. Open the project or page whose load performance needs auditing.
  4. Ask the agent to audit page load time; it will measure, verify the bottleneck, and recommend fixes.
  5. Consult references/rule.md for full implementation details and framework-specific guidance.

What this skill tells your AI

The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/page-load-time/SKILL.md and read by ahel’s review.

Studies show 53% of mobile users abandon sites that take longer than 3 seconds to load—slow pages directly hurt conversions, engagement, and SEO rankings.

Quick Reference

  • 3 seconds is the threshold where bounce rates spike dramatically
  • 53% of mobile users abandon sites taking over 3 seconds
  • Focus on Core Web Vitals: LCP, FID/INP, CLS
  • Test on throttled 3G to simulate real-world conditions

Check

Measure the page load time and verify it's under 3 seconds on a standard connection.

Fix

Optimize page load time through lazy loading, CDN usage, caching strategies, and resource optimization.

Explain

Explain how page load time affects bounce rate, SEO rankings, and user satisfaction.

Code Review

Review the routes, assets, and loading behavior that affect Keep page load time under 3 seconds. Flag exact files, requests, or rendering steps that add unnecessary network, CPU, or layout cost, and describe the measurement method used to confirm the issue.
