Guides the agent through migrating an existing Capacitor app project from CocoaPods to Swift Package Manager (SPM) for iOS dependency management. Covers prerequisite checks, inventorying installed Capacitor plugins, backing up customized iOS project files (Info.plist, AppDelegate.swift, Assets.xcassets, Base.lproj, App.entitlements, GoogleService-Info.plist, .xcconfig files, signing configuration), deleting the existing `ios/` folder, re-scaffolding with `npx cap add ios --packagemanager SPM`, restoring preserved files, re-syncing plugins, and verifying the build. Performs all migration steps manually — does not use the interactive `npx cap spm-migration-assistant` command. Do not use for Capacitor plugin projects, app projects already on SPM, app projects without an existing `ios/` folder, or non-Capacitor mobile frameworks.
Use when needing thread-safe primitives for performance-critical code. Covers Mutex (iOS 18+), OSAllocatedUnfairLock (iOS 16+), Atomic types, when to use locks vs actors, deadlock prevention with Swift Concurrency.
Automatically discover mobile development skills when working with iOS, Android, Swift, SwiftUI, React Native, mobile development, SwiftData, or app development. Activates for mobile development tasks.
Programmatic screenshot capture on macOS. Find window IDs with Swift CGWindowListCopyWindowInfo, control application windows via AppleScript (zoom, scroll, select), and capture with screencapture. Use when automating screenshots, capturing application windows for documentation, or building multi-shot visual workflows.
Use when the user needs mobile app design and development patterns for React Native, Flutter, or SwiftUI — including platform HIG compliance, gestures, and offline-first architecture. Triggers: user says "mobile", "iOS", "Android", "React Native", "Flutter", "SwiftUI", "app design", "mobile navigation", "touch targets", "offline-first".
Guide for building Apple-platform applications with Apollo iOS, the strongly-typed GraphQL client for Swift. Use this skill when: (1) adding Apollo iOS to a Swift Package Manager or Xcode project, (2) configuring `apollo-codegen-config.json` and running code generation, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions from SwiftUI views, (5) writing tests against generated operation mocks.
Native Swift and Metal specialist building high-performance 3D rendering systems and spatial computing experiences for macOS and Vision Pro
Govern inline documentation coverage and comment quality in repo-owned source files. Use when Codex needs to audit or fix file headers, type docs, function or method contract docs, non-obvious inline comments, generated-file exclusions, or repo documentation rules for TypeScript, JavaScript, and Swift projects, including setting up a reusable docs/rules policy in a project-agnostic way.
Automate multi-locale marketing screenshot capture for SwiftUI iOS apps with in-app capture system, demo data seeding, and element rendering.
Writes and reviews Swift App Intents code that exposes app actions and data to Siri, Shortcuts, Spotlight, widgets, Control Center, and Apple Intelligence. Use when adding AppIntent, AppEntity, OpenIntent, AppShortcutsProvider, EntityQuery, Focus Filters, AssistantEntity/AssistantIntent schemas, or when wiring SwiftData/networked data into intents.
3D chart visualization with Swift Charts using Chart3D, SurfacePlot, interactive pose control, and surface styling. Use when creating 3D data visualizations.
Build a custom cmux sidebar from a plain-language request. Use when the user asks for a custom sidebar, a sidebar that shows their workspaces/tabs/PRs/clock, a vibe-coded sidebar, or anything involving files in ~/.config/cmux/sidebars/. Covers authoring the interpreted SwiftUI-style file, enabling the beta flag, selecting it, and iterating with hot reload.
