Skill UI

Vaex is a high-performance Python library designed for lazy, out-of-core DataFrames. It enables processing and visualization of massive tabular datasets (billions of rows) that exceed available RAM. Users can perform fast statistics, aggregations, and build robust ML pipelines on big data files (CSV, Parquet, HDF5) without relying on distributed clusters, making it ideal for single-machine, large-scale analytics.

This skill provides a comprehensive workflow for scheduling social media posts using the Hootsuite REST API. It manages the entire publishing lifecycle: users first upload media (images or videos) to obtain a media ID. Subsequently, the skill uses this ID, along with text content and target profiles, to schedule the post across various social networks. It supports both single and bulk scheduling operations, ensuring efficient content automation.

This bundle collects comprehensive diagnostic evidence for Hootsuite operations. It gathers API connectivity status, social profile health, scheduled post status, and OAuth token validity into a single, portable archive. Use it when troubleshooting persistent issues like failed scheduling, authentication errors, or disconnected social accounts.

This comprehensive tool analyzes a detailed specification by synthesizing data from multiple source files (JSON, Markdown, etc.). It tracks phase completion, identifies task progress, maps boundary contexts (upstream/downstream dependencies), and proactively highlights necessary revalidation points or blockers, providing a single, unified report of the spec's completeness and current development state.

This comprehensive skill suite provides powerful capabilities for managing and manipulating Portable Document Format (PDF) files. Users can extract raw text content, programmatically fill out form fields, merge multiple documents into a single file, and split large PDFs into separate pages, streamlining complex document workflows.

This skill facilitates an interactive Quality Assurance (QA) session. Users can conversationally describe encountered bugs or issues. The agent clarifies the problem, explores the codebase for context and domain language, and then meticulously files durable GitHub issues. It supports both single-issue reports and breaking down complex problems into multiple, independently verifiable tickets, ensuring developers receive actionable, high-quality reports written from the user's perspective.

This comprehensive guide provides solutions for common and complex errors encountered when using WebContainer and StackBlitz environments. It covers essential fixes for cross-origin isolation headers (COOP/COEP), managing WebContainer boot failures using singleton patterns, resolving npm installation hangs, and handling file system errors (ENOENT). Use this skill to stabilize and debug complex web development sandboxes.

This comprehensive guide provides production-ready patterns for the WebContainer API, essential for building sophisticated online IDEs and code playgrounds. It covers key functionalities such as singleton WebContainer management, robust file system CRUD operations, process lifecycle management, jsh terminal emulation, and embedding projects using the StackBlitz SDK. Ideal for developers creating collaborative development environments.

Automates the deployment of static web files (HTML, CSS, JS, images) to a specified domain using Cloudflare Pages via the Wrangler CLI. This skill is ideal for hosting Single-Page Applications (React, Vue), landing pages, portfolios, or documentation sites. It stages the site files and injects necessary cache revalidation headers to ensure content freshness after redeployment.

Generates structured DESIGN.md files that serve as a single source of truth for AI-powered screen generation (Google Stitch). This skill translates complex, anti-generic design directives into precise semantic rules, covering typography, color calibration, motion physics, and layout principles to enforce a premium, high-agency UI/UX standard. It ensures outputs are sophisticated and avoid common AI design clichés.

Captures complete, full-page screenshots of any modern web page using the Chrome DevTools Protocol (CDP). Unlike standard tools, this utility handles Single Page Applications (SPAs), scrolling content, lazy-loaded images, and complex scroll containers, ensuring the entire visible content is captured in a single, high-fidelity PNG file. Ideal for documenting complex web flows and testing.

Generates a comprehensive, single-screen financial report in a self-contained HTML file. This skill is designed for analyzing key business metrics, including P&L summaries, MRR trends, KPI cards (Revenue, Gross Margin, Cash Runway), and top-accounts analysis. Ideal for quarterly or monthly financial reviews in SaaS or startup environments.
