Skill UI

A token-efficient protocol for accessing web content, including GitHub repos, specific URLs, and search queries. Uses layered fetch depth, API-first for GitHub, and skimming techniques to minimize tokens and avoid full-page fetching waste.

Expert in handling file uploads and cloud storage solutions like S3 and Cloudflare R2. Covers presigned URLs, multipart uploads, and image optimization. Ensures security by validating file types and preventing path traversal attacks. Optimizes performance for large files without blocking.

This skill enables deep web scraping, screenshots, and PDF parsing using the Firecrawl API. It extracts content from web pages, handles page interactions like clicking and scrolling, and processes multiple URLs in batch. Ideal for automated data collection tasks requiring robust extraction capabilities.

This skill helps audit and correct HTML metadata elements such as page titles, meta descriptions, canonical URLs, Open Graph tags, and Twitter cards. It ensures SEO best practices, fixes social share previews, and validates structured data like JSON-LD. Use it to maintain consistency across your website's technical SEO and improve search engine visibility while keeping changes minimal and scoped.

This skill provides a portable, framework-agnostic SEO system for React or React Native-for-web frontends. It centralizes site metadata in a constants module, derives canonical URLs, and generates per-route metadata including titles, descriptions, Open Graph, and Twitter cards. It also produces sitemaps, robots rules, RSS feeds, and typed JSON-LD without requiring manual meta tag copy-pasting.

This skill enables users to upload local images, such as screenshots or before-and-after comparisons, directly to GitHub using the GitHub CLI. It bypasses the lack of a public image upload API by mimicking the web UI's internal attachment flow, generating canonical `user-attachments` URLs. These URLs can then be seamlessly embedded into Pull Requests, Issues, or comments from the terminal.

HasData is a comprehensive cloud platform designed for extracting structured public web data. It supports three core execution modes: Web Scraping API for arbitrary URLs (including JS rendering), pre-parsed Scraper APIs for known platforms (like Google or Amazon), and asynchronous Scraper Jobs for bulk or recursive crawling. Ideal for market research, e-commerce intelligence, job data collection, and local business lead generation.

Use the HasData CLI to access real-time, structured web data from major platforms. This tool provides dedicated subcommands for various APIs (including Google SERP, Amazon, Zillow, Booking, etc.), enabling users to automate data collection, scrape specific URLs, and retrieve structured information like local business listings, product pricing, and real estate data directly from the command line.

Look up Hugging Face paper pages as markdown and query the papers API for structured metadata including authors, linked models, datasets, Spaces, GitHub repos, and project pages. Ideal for summarizing or analyzing AI research papers from hf.co or arXiv URLs and IDs.

Use this skill for Hugging Face Dataset Viewer API workflows that fetch subset/split metadata, paginate rows, search text, apply filters, download parquet URLs, and read size or statistics. It also covers creating and uploading datasets, and uploading agent traces.

Generates SQL validation notebooks for dbt PR changes with before/after comparison queries. Supports GitHub PR URLs and local repositories. Creates interactive notebooks for database validation across Snowflake, BigQuery, Redshift, and Athena. Includes schema inference from dbt_project.yml and model configs.

This skill provides a structured workflow to scan, audit, and fix web performance issues across Lighthouse and PageSpeed Insights pillars including Performance, Accessibility, Best Practices, and SEO. It helps improve Core Web Vitals like LCP, FCP, and CLS by identifying bottlenecks such as render-blocking resources and unused JavaScript. Users should provide reports or URLs for analysis.
