Web Performance Audit

warpdotdev/oz-skills
196 installs819 stars
Summary

This is a structured Chrome DevTools performance audit that walks you through the full workflow: trace capture, Core Web Vitals analysis, network waterfall inspection, and accessibility snapshots. It's opinionated in useful ways, telling you to skip non-issues like 0ms render-blocking resources and quantify impact before recommending changes. The Phase 5 codebase analysis is surprisingly thorough, detecting framework configs and checking for tree-shaking, polyfills, and compression settings. Best for methodical audits where you want a checklist-driven approach rather than ad-hoc profiling. Requires the chrome-devtools MCP server, which it checks upfront. The output format pushes you toward specific, actionable recommendations with estimated impact ratings.

webperf-resources

nucliweb/webperf-snippets

Intelligent network quality analysis with adaptive loading strategies. Detects connection type (2g/3g/4g), bandwidth, RTT, and save-data mode, then automatically triggers appropriate optimization workflows. Includes decision trees that recommend image compression for slow connections, critical CSS inlining for high RTT, and save-data optimizations (disable autoplay, reduce quality). Features connection-aware performance budgets (500KB for 2g, 1.5MB for 3g, 3MB for 4g+) and adaptive loading implementation guides. Cross-skill integration with Loading (TTFB impact), Media (responsive images), and Core Web Vitals (connection impact on LCP/INP). Use when the user asks about slow connections, mobile optimization, save-data support, or adaptive loading strategies. Compatible with Chrome DevTools MCP.

remotion-script-writer

sanky369/vibe-building-skills

Write a complete, render-ready Remotion video script as structured JSON: analyze the user's codebase or product, break the video into timed scenes, specify every visual element, animation, transition, and voiceover line, and list required assets and Remotion packages. Use whenever the user wants a Remotion video, a programmatic/code-rendered video, a product demo video of their app, an animated coding tutorial, a data-visualization video, or short-form animated social content — trigger on 'make a video of my app', 'Remotion', 'animated demo', 'code walkthrough video', 'render a video from code'. Produces a Remotion Script JSON (videoMetadata, scenes[], requiredAssets, technicalRequirements) that Remotion agent tooling can implement directly.
