Control a browser via Chrome DevTools Protocol (CDP) proxy. Use when: (1) navigating to URLs and reading page content, (2) taking screenshots, (3) executing JavaScript in the browser, (4) clicking elements or filling forms, (5) searching and installing Chrome Web Store extensions, (6) interacting with web APIs that require a real browser. NOT for: simple HTTP requests (use curl), local file operations, or when no CDP proxy is available.
Extract Udemy course content to markdown. Use when user asks to scrape/crawl Udemy course pages.
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.
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 browser automation setup using Chrome DevTools MCP as the primary path and the OpenCode browser extension as a fallback. Use when the user asks to set up browser automation, Chrome DevTools MCP, browser MCP, browser extension, or runs the browser-setup command.
Frontend debugging team using Chrome DevTools MCP. Dual-mode -- feature-list testing or bug-report debugging. Covers reproduction, root cause analysis, code fixes, and verification. CSV wave pipeline with conditional skip and iteration loops.
Uses Chrome DevTools MCP and documentation to troubleshoot connection and target issues. Trigger this skill when list_pages, new_page, or navigate_page fail, or when the server initialization fails.
Capture full-page screenshots of web pages via Chrome DevTools Protocol with zero dependencies. Useful for portfolios, case studies, and audit reports.
Frontend website debugging toolkit using Chrome DevTools Protocol with Playwright/WebKit fallbacks. Use this skill when: (1) Debugging CSS, HTML, or JavaScript issues on a webpage, (2) Taking screenshots to verify visual changes, (3) Inspecting DOM structure or console errors, (4) Testing responsive layouts, (5) Extracting selectors for automation, (6) Self-debugging frontend work Claude has created, (7) User says "debug this page", "check my site", "why doesn't this look right", or "fix the frontend". Supports Chrome (primary) and Safari/WebKit (via Playwright). Designed for agent-driven debugging loops.
Capture current page layout, styles, and structure from a live web page using Chrome DevTools MCP. Use when you need to understand the existing UI before making changes — captures screenshots, DOM structure, computed styles, and layout properties. Useful as a pre-implementation baseline for frontend or UI-affecting changes.
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.
