What it does
This is a set of instructions that makes an AI agent review JavaScript for event handlers (scroll, resize, typing, mouse movement) that fire very often and could cause lag or excessive API calls. The agent checks the code and, where appropriate, suggests wrapping those handlers in debounce (wait until activity stops) or throttle (limit how often they run), and explains the difference. It also says to check the browser behaviour so fixes target the real problem.
Great for
- Front-end developers tuning slow search boxes, scroll effects or resize handlers
- Teams reviewing client-side code for Interaction to Next Paint (INP) issues
- Developers learning when to pick debounce versus throttle
Skip it if
- Server-side code or backend-only performance problems, since the guidance targets browser event handlers
- Apps that already use a mature library for these patterns without needing review; the skill may suggest unnecessary changes
- Non-developers without access to the codebase, since the skill needs source code to review
Try asking
- “Review my search input handler in src/components/Search.js and tell me if it needs debounce.”
- “Check this scroll listener for throttling and suggest a fix.”
- “Explain the difference between debounce and throttle for my resize handler.”
- “Look at my React component's mousemove handler and flag anything that could cause jank.”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Point the agent at specific files or components so it can give exact line-level feedback.
- Ask it to state how to verify the fix in the browser, such as using DevTools performance recordings, since the skill asks for this.
- Treat suggested delay values (150-300ms for input, 100ms for scroll/resize) as starting points and test them for your app.
