Fetch web content as clean markdown using markdown-native endpoints, selector-based HTML extraction, or bundled fallback parsing. \n \n Prioritizes markdown-native responses (content-type: text/markdown) before falling back to HTML extraction \n Includes pre-configured selectors for common documentation sites (Anthropic, MDN, GitHub) and a generic fallback for article/main content regions \n Provides html2markdown with CSS selector support for fine-grained content isolation, excluding navigation

Web-based file upload, download, and management for CloudBase cloud storage via the JavaScript SDK. \n \n Supports four core operations: uploading files from browsers with progress tracking, generating temporary download URLs, deleting files, and downloading to local storage \n Requires CORS configuration in CloudBase console; add your frontend domain to security domains to prevent errors \n Uses file IDs in the format cloud://env-id/path/filename and supports folder hierarchies with / separator

Extract content from multiple URLs in parallel, token-efficiently. \n \n Handles webpages, articles, PDFs, and JavaScript-heavy sites with a single command \n Runs in a forked context to minimize token overhead compared to built-in WebFetch \n Supports batch extraction of multiple URLs with optional focus objectives \n Requires parallel-cli installation and authentication; outputs extracted content as markdown to a local file for follow-up queries \n

Iterative web game development with Playwright-based testing, screenshot validation, and deterministic time-stepping. \n \n Provides a structured workflow: implement small changes, run automated Playwright tests with controlled input bursts and frame pauses, capture screenshots and text state, then inspect and adjust \n Requires window.render_game_to_text() to expose game state as JSON and window.advanceTime(ms) for deterministic frame stepping during automated tests \n Includes a Playwright cli

Fast web search for current information, research, and fact-finding across the internet. \n \n Executes single objective-based queries or multiple keyword searches in parallel, returning up to 10 results with excerpts and metadata \n Supports time-sensitive filtering via --after-date and domain-specific searches with --include-domains \n Outputs structured JSON with titles, URLs, publish dates, and excerpts for easy parsing and follow-up queries \n Requires inline citations for every claim using

Web search with AI-optimized results, relevance scoring, and advanced filtering via Tavily API. \n \n Supports three topic types (general, news, finance) and two search depths (basic, advanced) with optional AI-generated answer summaries \n Includes domain filtering to include or exclude specific sites, time-range filtering (day, week, month, year), and configurable result counts \n Returns structured results with relevance scores, publication dates, and optional raw page content; supports both

Execute comprehensive web application security testing using Burp Suite's integrated toolset, including HTTP traffic interception and modification, request analysis and replay, automated vulnerability scanning, and manual testing workflows. This skill enables systematic discovery and exploitation of web application vulnerabilities through proxy-based testing methodology.

Web frontend development with CloudBase integration, static hosting deployment, and SDK-based authentication. \n \n Covers project structure conventions (src/dist/cloudfunctions directories), modern build systems (Vite, Webpack), and hash routing for static hosting compatibility \n Provides CloudBase Web SDK integration patterns for database, cloud functions, and authentication, with strict rules against implementing login logic in cloud functions \n Includes deployment guidance for CloudBase st

Unified search with automatic provider selection across seven search engines. \n \n Intelligently routes queries to the best provider: Serper for shopping, Tavily for research, Exa for semantic similarity, Perplexity for direct answers with citations, You.com for real-time info, Querit for multilingual searches, and SearXNG for privacy \n Requires only one API key to start; all provider keys are optional and can be added incrementally \n Includes automatic fallback to alternate providers on rate
