Skill UI

This comprehensive workflow guides the process of building and deploying new features that must maintain consistent functionality and design across multiple operating systems (web, mobile, and desktop). It strictly follows an API-first architecture, starting with defining shared API contracts (OpenAPI/GraphQL) and a unified design system. The process then guides parallel implementation across specialized stacks like React/Next.js, SwiftUI, and Jetpack Compose, ensuring high code consistency and faster time-to-market.

Guides designers through using the Penpot MCP tools to craft professional UI/UX for web, mobile, and desktop apps, covering workflows, design systems, accessibility checks, and setup/troubleshooting steps for the Penpot MCP server.

Use for live Windows or macOS GUI tasks that structured tools cannot complete. Discover approved apps and windows, observe current state, act via semantic elements or shortcuts, and verify every requested outcome. Includes an operating loop for reliable desktop automation and visual verification.

Master secure Electron desktop application development covering multi-process architecture, IPC security, packaging, and auto-update. Learn to build production-ready apps with contextIsolation, preload scripts, and native OS integration while optimizing performance and bundle size.

Build and deploy the same feature consistently across web, iOS, Android, and desktop using API-first architecture, shared design systems, and parallel implementation strategies to achieve cross-platform feature parity.

This skill provides pre-configured project scaffolding templates for initiating new applications from scratch. It covers 12 diverse technology stacks including Next.js, Express, Python FastAPI, React Native, Flutter, and more. Users can select the appropriate template based on their project type, such as full-stack web apps, APIs, mobile applications, or desktop software. It streamlines the setup process by offering ready-made structures and configurations tailored to specific development needs.

Build end-to-end tests with TestDriver.ai, an AI code reviewer that runs every pull request in a real desktop sandbox, finds bugs, and creates regression tests for web, Electron, and native apps.

Prepare, validate, submit, and monitor Windows desktop apps in Microsoft Partner Center, covering MSIX packaging, Store identity, listings, WACK testing, certification, and publishing automation.

Drive native desktop apps through an Automation REPL: bind applications, inspect accessibility trees, type text, click, and capture screenshots while honoring OS permissions and user stop requests.

Platform guide for agent-desktop CLI on macOS: granting Accessibility and Screen Recording permissions, headed input, surfaces, Notification Center, Chromium/Electron apps, and troubleshooting.

Master secure Electron desktop application development. Learn multi-process architecture, secure IPC communication, context isolation, preload scripts, and packaging with electron-builder. Ideal for building production-ready native apps with auto-update capabilities and code signing.
