Analyze a Chrome DevTools Performance trace JSON file for performance anomalies, producing a structured audit report with critical issues, warnings, metrics, timeline hotspots, and actionable recommendations.
Expert guidance for R package development following best practices for devtools, testthat, roxygen2, and R ecosystem tools
Production-tested setup for Zustand state management in React. Includes patterns for persistence, devtools, and TypeScript patterns. Prevents hydration mismatches and render loops.
Use SweetLink to connect your AI agent to a real browser tab. Like Playwright, but works in your current tab. Enables authentication, screenshots, smoke tests, and DevTools telemetry without headless automation.
Use when the user asks to capture a full-page screenshot, long screenshot, or complete page capture of a web page. Handles SPA scroll containers, lazy-loaded images, and very tall pages via Chrome DevTools Protocol with zero external dependencies.
Capture full-page screenshots of web pages via Chrome DevTools Protocol with zero dependencies. Useful for portfolios, case studies, and audit reports.
Diagnose MCP validation dependencies (Brave Search, Chrome DevTools) and output exact setup snippets.
Analyze any website's UI style using ChromeDevTools to extract precise CSS tokens, animations, and interaction states. Handles complex sites and anti-bot measures by guiding the user. Triggers on "analyze this site", "extract UI style", "create design system from [URL]", or "learn visual style".
Guide users through the get started setup and Chrome DevTools demo.
Use this skill when debugging applications using Chrome DevTools, lldb, strace, network tools, or memory profilers. Triggers on Chrome DevTools, debugger, breakpoints, network debugging, memory profiling, strace, ltrace, core dumps, and any task requiring systematic debugging with specialized tools.
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.
Intelligent media optimization with automated workflows for images, videos, and SVGs. Includes decision trees that detect LCP images (triggers format/lazy-loading/priority analysis), identify layout shift risks (missing dimensions), and flag lazy loading issues (above-fold lazy or below-fold eager). Features workflows for complete media audit, LCP image investigation, video performance (poster optimization), and SVG embedded bitmap detection. Cross-skill integration with Core Web Vitals (LCP/CLS impact) and Loading (priority hints, resource preloading). Provides performance budgets and format recommendations based on content type. Use when the user asks about image optimization, LCP is an image/video, layout shifts from media, or media loading strategy. Compatible with Chrome DevTools MCP.
