Use when fixing stateful editor regressions, especially rich-text or Markdown editor bugs involving caret geometry, cursor jumps, selection deletion crashes, paste formatting, keyboard input, markdown shortcuts, list or heading history bugs, local engine forks, TDD, UI tests, simulator/device validation, and commit/push sequencing across dependent repos.

Generate Kauch exercise and equipment icons with OpenAI image generation. Use when creating or refreshing workout artwork such as kettlebells, barbells, dumbbells, machines, or movement icons like push-ups, squats, and deadlifts, especially when the output should match Kauch's playful 3D style and BrandAccent color.

Develop native iOS apps with Swift for this repo's architecture. Covers SwiftUI, protocol-backed services, Swift concurrency, Observation, and SwiftData persistence.

Maintain Kauch's landing page artifact pipeline. Use when working on the landing page, screenshot generation, baked device frames, marketing scenario seeds, screenshot manifests, or landing-page content that should stay synced to real app UI.

Reviews Swift code for concurrency correctness, modern API usage, and common async/await pitfalls. Use when reading, writing, or reviewing Swift concurrency code, especially when fixing actor isolation, Sendable, strict concurrency, or Swift 6.2 migration issues.

Writes, reviews, and improves Swift Testing code using modern APIs and best practices. Use when reading, writing, or reviewing projects that use Swift Testing.

Writes, reviews, and improves SwiftData code using modern APIs and best practices. Use when reading, writing, or reviewing projects that use SwiftData.

Implement, review, or improve SwiftUI animations and transitions. Use when adding explicit animations with withAnimation, configuring implicit animations with .animation(_:body:) or .animation(_:value:), configuring spring animations (.smooth, .snappy, .bouncy), building phase or keyframe animations with PhaseAnimator/KeyframeAnimator, creating hero transitions with matchedGeometryEffect or matchedTransitionSource, adding SF Symbol effects (bounce, pulse, variableColor, breathe, rotate, wiggle), implementing custom Transition or CustomAnimation types, or ensuring animations respect accessibilityReduceMotion.

Apple device framing CLI. Use when wrapping raw simulator screenshots or PNG assets inside official Apple device bezels (iPhone, iPad, Apple Watch), when producing marketing or App Store hero images, landing page screenshots, OG images, or any composite that needs a real device frame around a capture. Also use when the user asks to "frame", "bezel", "mock up", or "render in a device" an existing screenshot, or to capture and frame directly from the booted simulator in one step.

Search, shortlist, and download SVG icons from the Nucleo icon catalog hosted in a private GitHub repo. Use when Codex needs to pick icons for UI features, product concepts, navigation, status states, or marketing surfaces; compare outline, fill, micro-bold, or duo variants; or fetch exact SVG assets into another repo without cloning or manually browsing thousands of files.

Process, trim, and bundle stock video clips for the onboarding carousel. Use when the user provides raw video files to select from, replace, or add onboarding videos.
