Skill UI

A comprehensive guide for implementing Monochromatic User Interfaces across Web, iOS, and Android. Learn how to achieve high elegance and strict color discipline by restricting the palette to variations (tints, tones, shades) of a single base hue. Includes detailed CSS, SwiftUI, and Flutter examples, emphasizing accessibility, texture usage, and color theory principles.

Handle n8n files and binary data across uploads, downloads, transforms, multimodal inputs, agent tools, and chat surfaces. Covers where binary lives, how to read/write it, preventing data loss, and the AI-agent tool boundary.

This skill guides users on writing Python code within n8n Code nodes, focusing on standard library usage. It details critical limitations regarding external packages, offering workarounds for HTTP requests and data analysis. Users learn when to prefer Python over JavaScript and how to handle specific syntax requirements safely within the n8n environment.

This skill covers designing visible and recoverable error handling for n8n workflows. It focuses on using error outputs, retry mechanisms, and Error Trigger workflows to prevent silent failures in unattended automation. Learn how to configure node-level retries and wire error paths correctly to ensure alerts and diagnostics are exposed only when necessary.

A comprehensive technical guide covering the entire lifecycle of Python packaging. It teaches developers how to structure, build, test, and distribute robust Python libraries using modern standards like pyproject.toml, generating wheels, and publishing artifacts reliably to PyPI or private package indexes. Ideal for creating reusable, professional-grade Python code.

This guide provides comprehensive patterns for designing and implementing secure multi-tenant SaaS applications using shared databases. It covers critical techniques like Row-Level Security (RLS) in PostgreSQL, implementing tenant-aware middleware in TypeScript (Express/Fastify), and enforcing data scoping at the ORM level (Prisma/Drizzle). Learn how to prevent data leakage and manage tenant isolation across shared schemas.

This skill specializes in transforming theoretical threat models, risk assessments, and business context into concrete, actionable security requirements. It is essential for writing detailed security user stories, defining robust acceptance criteria, building comprehensive security test cases, and ensuring compliance requirement mapping. Use it when bridging the gap between identifying a vulnerability and specifying how the system must be secured.

This guide details how to use Skyvern's AI-powered Command Line Interface (CLI) for advanced browser automation. Users can perform tasks such as quick data validation, structured data extraction, form filling, secure login, and building complex, multi-step, reusable workflows across various websites. It offers solutions for scenarios where deterministic selectors fail.

Guides how to craft detailed prompts for Google Stitch so it generates high-quality web and mobile UI designs, covering specificity, visual style, multi-screen structure, platform targeting, and iterative refinement.

A comprehensive guide detailing how to refactor large, complex SwiftUI views into smaller, more stable, and explicit components. It emphasizes adopting a lightweight state approach (favoring local state and environment variables over excessive view model layers) to improve data flow, readability, and overall code maintainability in modern iOS development.

Fetch and explain TraderSpy's AI crypto futures signals: entry, take-profit ladder, stop, triggers, status against the live price, and how recent signals resolved. Use for 'latest signals'.

This guide details how to deploy and manage web projects on Vercel using token-based authentication via the CLI. It provides comprehensive steps for locating and setting the VERCEL_TOKEN, identifying project IDs, and executing deployment commands (including linking and direct deployment) without relying on interactive login.
