Best practices and example-driven guidance for building SwiftUI views and components, including navigation hierarchies, custom view modifiers, and responsive layouts with stacks and grids. Use when creating or refactoring SwiftUI UI, designing tab architecture with TabView, composing screens with VStack/HStack, managing @State or @Binding, building declarative iOS interfaces, or needing component-specific patterns and examples.
Use XcodeBuildMCP to build, run, launch, and debug the current iOS project on a booted simulator. Trigger when asked to run an iOS app, interact with the simulator UI, inspect on-screen state, capture logs/console output, or diagnose runtime behavior using XcodeBuildMCP tools.
Scaffold, build, and package SwiftPM-based macOS apps without an Xcode project. Use when you need a from-scratch macOS app layout, SwiftPM targets/resources, a custom .app bundle assembly script, or signing/notarization/appcast steps outside Xcode.
Implement, review, or improve SwiftUI features using the iOS 26+ Liquid Glass API. Use when asked to adopt Liquid Glass in new SwiftUI UI, refactor an existing feature to Liquid Glass, or review Liquid Glass usage for correctness, performance, and design alignment.
Audit and improve SwiftUI runtime performance from code review and architecture. Use for requests to diagnose slow rendering, janky scrolling, high CPU/memory usage, excessive view updates, or layout thrash in SwiftUI apps, and to provide guidance for user-run Instruments profiling when code review alone is insufficient.
Refactor and review SwiftUI view files with strong defaults for small dedicated subviews, MV-over-MVVM data flow, stable view trees, explicit dependency injection, and correct Observation usage. Use when cleaning up a SwiftUI view, splitting long bodies, removing inline actions or side effects, reducing computed `some View` helpers, or standardizing `@Observable` and view model initialization patterns.
Analyze and optimize React component performance issues (slow renders, re-render thrash, laggy lists, expensive computations). Use when asked to profile or improve a React component, reduce re-renders, or speed up UI updates in React apps.
Build, refactor, or review macOS menubar apps that use Tuist and SwiftUI. Use when creating or maintaining LSUIElement menubar utilities, defining Tuist targets/manifests, implementing model-client-store-view architecture, adding script-based launch flows, or validating reliable local build/run behavior without Xcode-first workflows.
Use for dynamic inspection and navigation of the Blokada app through the repo-local Appium machine session. Trigger when Codex needs to explore the live native UI on a real device, inspect labels or structure, tap through screens, capture screenshots or XML on demand, or verify interactive behavior without writing a static WDIO spec. The current workflow is implemented for iOS, but the skill name stays generic so it can later cover other Appium-backed platforms too.

为 Fantastic-admin 框架生成独立的表单页面，使用 vee-validate + zod 验证，全部使用框架内建 Fa* 组件。当用户说：'帮我做一个用户信息填写页'、'我只需要一个提交表单，不需要列表'、'做个设置页面，有几个输入框和保存按钮'、'生成一个注册/编辑/配置表单页'、'只要表单页，不需要增删改查'，即使用户只是说'做个表单页面'也应触发此技能。
在 Fantastic-admin 框架中创建插槽，向布局的任意位置注入自定义内容。当用户提到以下任何需求时必须使用此技能：在头部/侧边栏/工具栏/标签栏加东西、logo 旁边加内容、侧边栏底部加用户信息、加个悬浮按钮、在导航菜单右侧加自定义组件、想在框架布局某个区域插入内容、在页面顶部或底部插入全局横幅/公告/版权栏。即使用户只是说"在顶部加个 XX"或"侧边栏加点东西"，也应触发此技能。支持 19 个插槽位置。
为 Fantastic-admin 框架创建和定制主题配色方案，始终同时生成明色（light）和暗色（dark）两套主题。当用户提到以下任何需求时必须使用此技能：换主题颜色、换配色、做一个 XX 风格的主题、主题太单调了、品牌色是 XXX 帮我生成主题、把 tweakcn 配色转成框架主题、想要暗色/冷色/暖色调、根据设计稿颜色生成主题。即使用户只是描述一种感觉（"清新"、"沉稳"、"科技感"）或提供一个颜色值（"#2563EB"），也应触发此技能。支持"吉卜力"、"赛博朋克"、"莫兰迪"、"北欧极简"等专业设计风格关键词。
为 Fantastic-admin 框架生成 Pinia Store 模块。当用户提到以下任何需求时必须使用此技能：多个页面需要共享数据、全局状态管理、数据需要持久化（刷新后还在）、登录状态/用户信息需要缓存、购物车/通知/权限等全局数据、需要在组件外访问状态。即使用户只是说"这个数据要全局共享"或"刷新后数据不能丢"，也应触发此技能。触发关键词：创建 store、全局状态、状态管理、pinia、持久化、共享数据。
优化 Vue 页面，用 Fantastic-admin 框架内建组件（packages/components/）替换自定义实现和原生 HTML。当用户说：'帮我优化这个页面'、'把这些原生 HTML 换成框架组件'、'用 FaCard/FaModal/FaButton 重构一下'、'这个页面太乱了'、'统一一下 UI 风格'、'用内建组件替换自定义弹窗/分页/加载'，即使用户只是说'看看这个页面能不能改进'也应触发此技能。
Detect, suggest, and evaluate GoF design patterns in TypeScript/JavaScript codebases. Use when refactoring code, applying singleton/factory/observer/strategy patterns, reviewing pattern quality, or finding stack-native alternatives for React, Angular, NestJS, and Vue.
Wrap high-verbosity shell commands with RTK to reduce token consumption. Use when running git log, git diff, cargo test, pytest, or other verbose CLI output that wastes context window tokens.
How FabLL (faebryk.core.node) maps Python node/trait declarations into the TypeGraph + instance graph, including field/trait invariants and instantiation patterns. Use when defining new components or traits, working with the Node API, or understanding type registration.
How the Zig↔Python binding layer works (pyzig), including build-on-import, wrapper generation patterns, ownership rules, and where to add new exported APIs. Use when adding Zig-Python bindings, modifying native extensions, or debugging C-API interactions.
How the Faebryk parameter solver works (Sets/Literals, Parameters, Expressions), the core invariants enforced during mutation, and practical workflows for debugging and extending the solver. Use when implementing or modifying constraint solving, parameter bounds, or debugging expression simplification.
Define Serverpod endpoints, use Session, pass parameters, and call from client. Use when creating RPC endpoints, working with Session, or client code generation.
Define Serverpod data models in YAML (.spy.yaml), serialization, database tables, relations, enums, and exceptions. Use when creating or editing models, database schema, .spy.yaml files, or Serverpod ORM entities.
