Find and fix the actual performance bottleneck in an interface, then measure the result. Use when an interface is measurably slow, or when performance is a stated requirement. Covers Core Web Vitals (LCP, INP, CLS), load time, bundle size, render cost, and the discipline of not optimizing what is not slow.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Performance is a feature. Identify the actual bottleneck for THIS interface, fix it, then measure. Don't optimize what isn't slow. ## Assess Performance Issues Understand current performance and identify problems: 1. **Measure current state**: - **Core Web Vitals**: LCP, INP, CLS scores - **Load time**: Time to interactive, first contentful paint - **Bundle size**: JavaScript, CSS, image sizes - **Runtime performance**: Frame rate, memory usage, CPU usage - **Network**: Request count, payload sizes, waterfall 2. **Identify bottlenecks**: - What's slow? (Initial load? Interactions? Animations?) - What's causing it? (Large images? Expensive JavaScript? Layout thrashing?) - How bad is it? (Perceivable? Annoying? Blocking?) - Who's affected? (All users? Mobile only? Slow connections?) **CRITICAL**: Measure before and after. Premature optimization wastes time. Optimize what actually matters. ## Optimization Strategy Create systematic improvement plan: ### Loading Performance **Optimize Images**: - Use modern formats (WebP, AVIF) - Proper sizing (don't load 3000px image for 300px display) - Lazy loading for below-fold images …

How to install
mdr add jzkk720/cubecloud-skills-bundle-kit/impeccable-optimize@sha256:63c25d9abcfb22aeThe line at the top of this page pins the label git:20260913.453cd42, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
