Optimize interaction to next paint
SkillMediainteraction-to-next-paint is a skill for AI agents that audit slow page loads, heavy assets, and rendering delays related to Optimize interaction to next paint. It guides the agent to verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes, so fixes target the real cause.
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 Optimize interaction to next paint skill
What your AI can do with it
- Audit slow page loads, heavy assets, and rendering delays
- Investigate issues related to Optimize interaction to next paint
- Verify the actual bottleneck in DevTools before recommending changes
- Check render-delay causes using Lighthouse
- Confirm bottlenecks against field data
Getting started
- Have an AI agent that can load skills.
- Add the interaction-to-next-paint skill to the agent's available skills.
- Give the agent a page or dataset to audit and ask it to check for interaction-to-next-paint related delays.
- Have DevTools, Lighthouse, or field data available so the agent can verify the bottleneck before changes are recommended.
What this skill tells your AI
The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/interaction-to-next-paint/SKILL.md and read by ahel’s review.
INP replaced FID as a Core Web Vital in 2024—it measures how quickly your page responds to user interactions throughout the session, not just the first interaction.
Quick Reference
- INP measures responsiveness to ALL interactions—target under 200ms
- Break up long tasks into smaller chunks
- Use web workers for heavy computation
- Optimize event handlers and avoid blocking the main thread
Check
Measure INP using Chrome DevTools or PageSpeed Insights. Verify interaction responses occur within 200ms.
Fix
Optimize event handlers, break up long tasks, use web workers for heavy computation, and reduce main thread blocking.
Explain
Explain how INP measures overall page responsiveness by tracking the latency of all user interactions during a page visit.
Code Review
Review the routes, assets, and loading behavior that affect Optimize interaction to next paint. 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.

Questions
- When should this skill be used?
- Use it when auditing slow page loads, heavy assets, or rendering delays related to Optimize interaction to next paint.
- Does it recommend fixes right away?
- No. It first verifies the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.
- What tools does it rely on?
- It works with DevTools, Lighthouse, or field data to confirm the real render-delay bottleneck.
