Coding standards, frameworks, refactoring, and code review (15.8K skills)
Review SwiftUI code for outdated APIs, data flow, navigation, accessibility, and performance. Receive findings grouped by file, with line references, brief before-and-after fixes, and a prioritized summary of the changes that matter most.
Turn specifications into a detailed implementation plan before coding. Break work into small tasks with exact file paths, code, test commands, and interfaces so another developer or agent can follow the plan.
Review Swift async/await code, which runs tasks without blocking while waiting. Check shared state, task structure, cancellation, streams, and migration issues, then receive file-specific findings with before-and-after fixes and a prioritized summary.
Build and configure web servers with Nitro, including request handlers, caching, storage, and scheduled tasks. The skill also guides deployment to supported runtimes and platforms, plus migration from Nitro v2 to v3.
Configure Vite projects for development and production builds, create plugins, and build libraries or apps with server-side rendering, where pages are generated on the server. The skill also covers migrating configuration to Vite 8.
Set up JavaScript and TypeScript projects using Anthony Fu’s conventions for code organization, development tools, and package publishing. Establish shared checks for formatting, types, unused code, and tests before committing changes.
Configure UnoCSS and style interfaces with utility classes, small reusable styling instructions. Use project settings to define custom rules, shortcuts, themes, and presets for features such as icons, typography, and attribute-based styling.
Create a GitHub pull request from the current branch with a structured title, a clear explanation of behavior changes, and recorded check results. For UI changes, attach before-and-after screenshots so reviewers can assess the visual differences.
Build Vue 3 components with TypeScript and Composition API, a way to organize component logic. Define inputs, events, and two-way bindings, manage reactive data, and use built-in components for transitions and state preservation.
Build documentation sites from Markdown with VitePress, then configure navigation, search, and themes. The skill also covers embedding Vue components, organizing multilingual content, and preparing deployment settings for supported hosting platforms.
Manage Node.js dependencies with pnpm, from installing packages to coordinating multiple projects in one workspace. The skill covers shared version settings, third-party package patches, dependency overrides, and consistent installation procedures for automated build environments.
Organize shared data and update logic in Vue apps using Pinia stores, containers for application state. The skill guides store definitions, reactive data access, communication between stores, testing, and integration with Nuxt and server-side rendering.
Develop Vue web applications with Nuxt, covering pages, data fetching, shared state, and server API routes. Configure rendering on the server or in the browser, and prepare deployment settings for supported platforms.
Continue an existing OpenSpec change by creating one next document. Check progress and dependencies, follow the workflow's template, and report what was completed and which documents are now available to create.
Learn the complete OpenSpec workflow through a small task in an actual codebase. The agent explains each stage while creating a proposal, specifications, design, and tasks, then implements the change and archives its records.
Set up a new OpenSpec change for a feature, fix, or modification. Create its working directory, show the document sequence and current status, and present the first template so drafting can begin.
Explore development ideas and problems through conversation, code investigation, diagrams, and comparisons. The skill helps clarify requirements, weigh approaches, and surface risks before or during a change, with optional documentation of decisions when requested.
Create the OpenSpec documents needed to begin implementing a feature or fix. Follow the workflow's dependency order and templates, using completed documents as context until all prerequisites for implementation are ready.
Update main specifications from delta specs, documents describing intended changes. Apply requirement additions, edits, removals, and renames while preserving unrelated content and keeping the change active for further implementation work.
Archive several OpenSpec changes together after reviewing their documents, task completion, and specification conflicts. The agent checks actual code to decide which specification updates to apply, asks for confirmation, and reports successes, skipped changes, and failures.
Plan and implement mobile apps for iOS and Android, covering screens, state management, networking, local storage, and tests. Includes guidance for choosing native development or shared development across platforms with React Native and Flutter.
Organize development work across multiple AI agents by defining roles, splitting tasks, sharing status, and resolving conflicts. Use file ownership rules and Codex agent tools to coordinate parallel changes without assigning simultaneous writers to one file.
Find repeated interface elements and shared visual values, then turn them into reusable components and design tokens, named values for colors or spacing. Update existing uses and document the additions within the project's design system.
Choose a programming language for a development task and find the corresponding language guide. This index maps web development, systems programming, automation, and security tools to options including Python, Go, Rust, TypeScript, Java, C/C++, and Shell.
