Coding standards, frameworks, refactoring, and code review (16.4K skills)
Build Android interfaces in Expo using Jetpack Compose components and modifiers, which control layout and appearance. The skill guides component selection, sizing, scrollable lists, and XML icons for SDK 55.
Connect an Expo project to the Codex app Run button by creating a local launch script and action configuration. Start the development server from the app, view its logs, and optionally add platform-specific launch buttons.
Translate Figma designs into SwiftUI code, or bring SwiftUI views, screens, and design tokens into Figma. The guidance preserves iOS interface patterns, semantic colors, and SF Symbols names across both directions.
Build development clients for Expo apps that use custom native code. Covers local and cloud builds, device installation, TestFlight distribution, and connecting installed clients to a local development server.
Create server endpoints in Expo Router and deploy them with EAS Hosting. Use them to keep API keys off the client, validate incoming data, access databases, proxy external services, and receive webhook notifications.
Create and maintain Code Connect templates that link published Figma components to existing code components. Map text, variants, visibility settings, and nested components so the displayed code snippets reflect the selected design properties.
Turn Figma designs into screen code that fits an existing project. The workflow reuses existing components and shared style values, follows design notes, and uses exported images and icons to preserve the design’s appearance.
Write and review Cloudflare Workers code using current official guidance. Check configuration, asynchronous tasks, large response handling, secrets, and service connections, with findings supported by documentation, code locations, or validation results.
Choose automatic layouts for diagrams made of connected nodes. Match algorithms and tools to the graph structure, then plan connector routes, overlap handling, and stable placement so readers can follow relationships and edits remain predictable.
Build AI agents on Cloudflare Workers with the Agents SDK. Implement persistent state, real-time chat, scheduled tasks, multi-step background workflows, and MCP servers, using current Cloudflare documentation to guide implementation.
Review Git code changes using the CodeRabbit CLI. Receive a summary of the changes and issues ordered by severity, with affected file paths, practical impact, and concrete suggestions for follow-up fixes.
Build and review Cloudflare Durable Objects for applications that retain shared state, such as chat rooms, games, and booking systems. Covers SQLite storage, remote method calls, WebSockets, scheduled work, Workers integration, configuration, and Vitest tests.
Integrate charts and architecture diagrams into React or Next.js apps. Plan which parts run in the browser, separate rendering from application state, and address loading performance, mobile layouts, accessibility, and shareable views.
Design and build visual stories where scrolling changes charts, maps, or video. Plan meaningful scene transitions, choose suitable implementation tools, and provide mobile layouts and static alternatives for readers who prefer reduced motion.
Build charts and interactive diagrams in TypeScript with explicit data types and clear component boundaries. Guides library selection, data validation, interaction design, and shareable view settings to support maintainable visualization code.
Build and deploy AI agents on Cloudflare Workers using the Agents SDK. Supports persistent conversation state, live WebSocket connections, scheduled tasks, and tool integration, with guidance for connecting browser or React chat interfaces.
Build isolated code execution environments on Cloudflare Workers for AI-generated code, scripts, and build pipelines. Covers running commands, managing files, preserving interpreter state, exposing service previews, and cleaning up sandbox resources.
Choose, create, and review software diagrams that explain structure, interactions, workflows, states, or data relationships. Select suitable notation and rendering tools, then plan static exports or interactive views with readable layouts, accessible controls, and validation.
Customize windows in macOS SwiftUI apps, including titles, toolbars, drag areas, sizing, placement, and restoration. It helps give main windows, utility panels, and media players behavior suited to their purpose.
Build or refactor SwiftUI screens using component examples for navigation, state, layouts, and controls. The skill guides screen composition, asynchronous loading, previews, and build checks while following existing project conventions and supported operating system versions.
Refactor large macOS SwiftUI views into focused files and components. Clarify window state, selection, commands, and AppKit integration while preserving existing behavior and keeping the main layout stable as users change selections.
Build macOS app windows and interfaces with SwiftUI, including menus, toolbars, settings, sidebars, and inspectors. Guides state ownership and file organization while keeping keyboard actions, multiple windows, and system appearance in mind.
Build, run, and test macOS Swift packages using SwiftPM, the Swift package manager. Identifies available libraries and executables, selects relevant commands and tests, and reports results with the main blocker when something fails.
Build and maintain interfaces with shadcn/ui components, reusable pieces such as forms, cards, and dialogs. Find suitable components, follow project settings, fix composition and styling issues, and review updates while preserving local changes.
