Every Agent Skill we could find on GitHub, deduplicated by content. 79 566 files from 1 758 authors, of which 61 913 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
This skill should be used when the user asks to "test for directory traversal", "exploit path traversal vulnerabilities", "read arbitrary files through web applications", "find LFI vulnerabilities", or "access files outside web root".

Firebase gives you a complete backend in minutes - auth, database, storage, functions, hosting. But the ease of setup hides real complexity.

Gather the site name and layout preference before building a WordPress site. Run this before creating any new site.
Import and rebuild a website from a closed platform (Wix, Squarespace, Webflow, Shopify, GoDaddy, Hostinger, HubSpot, Weebly) into a Studio WordPress site. Extracts pages/posts/products + media, then reconstructs the design as editable blocks + WooCommerce OR as a high-fidelity replica theme. Invoke when the user wants to migrate, import, liberate, or rebuild a site from one of these platforms.
Run an on-page SEO audit on a WordPress site and get actionable recommendations to improve search visibility.
Write editable WordPress block markup for local Studio sites, including core/html limits, block-theme layout rules, full-width sections, validation, and skeleton-first page/CSS recipes.
Answer WordPress.com plan, pricing, upgrade, and feature-tier questions (plan names, what each tier unlocks — plugins, themes, custom code, SSH, hosting — and current prices) from authoritative live data. Load before answering ANY plan, pricing, or feature-gating question; never answer these from memory.
Open a browser with visual annotation tools. The user clicks elements on their site and leaves feedback — the agent reads annotations and makes changes. Use this when the user wants to point at specific elements to fix, tweak, or redesign.
Run a frontend performance audit on a WordPress site and get actionable optimization recommendations.
Choose recommended plugins and plugin-provided blocks for features core WordPress blocks do not cover - ecommerce (WooCommerce), forms and newsletters (Jetpack), online courses and quizzes (Sensei LMS), polls, surveys and ratings (Crowdsignal), spam protection (Akismet) - while keeping generated content editable and avoiding raw HTML fallbacks. Any request to sell products or build a shop, store, or storefront requires WooCommerce with products.
Analyze and optimize a WordPress site's category taxonomy. Exports all posts, uses AI to suggest an improved category structure — merging duplicates, retiring dead categories, creating missing ones, writing descriptions, and re-categorizing posts. Run this when the user wants to clean up or improve their categories.

Templates and guidelines for creating new WordPress blocks from scratch — load this before generating block files
Compose a single liberated page's WordPress block-editor markup from its rendered HTML and screenshot. Inputs are a sanitized HTML file, a desktop screenshot, the design-foundation tokens, the URL's archetype (page/post/product/etc.), and the source URL. Output is a string of valid block markup that round-trips through parse_blocks, uses theme tokens (no inlined hex colors), and contains only text drawn from the source HTML. Call per-page during the streaming watch loop after extraction has produced HTML+screenshot for that URL. Use when a freshly-imported page needs `post_content` upgraded from raw HTML into block-editor markup so the replica theme's tokens, gradients, and patterns actually render.
Build a new platform adapter to extract content from an unsupported platform (Blogger, Ghost, Tumblr, etc.)
