What this skill does
Media You MUST use this skill for ANY camera, photo, audio, haptic, or media playback work. <!-- AXIOMAUDITORINLINEBEGIN — rewritten for Codex by scripts/build-codex.ts; do not hand-edit --> Auditors are skills here. Where this router says "Launch some-auditor agent", invoke the matching Codex skill instead — same procedure, no Claude Code agent required. Available: axiom-audit-camera. The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run. <!-- AXIOMAUDITORINLINEEND --> Quick Reference Symptom / Task Reference ---------------- ----------- Camera capture, AVCaptureSession See skills/camera-capture.md Slow camera launch / deferred start (iOS 26+), ProRes recording via Pro Video Storage (OS27) See skills/camera-capture.md Patterns 8-9 Camera API (RotationCoordinator, etc.) See skills/camera-capture-ref.md Center Stage front camera (iPhone 17), dynamic aspect ratio, smart framing, 24/48 MP capture See skills/camera-capture-ref.md Camera freezes, black preview, rotation See skills/camera-capture-diag.md Photo pickers, library access See skills/photo-library.md PHPicker, PhotosPicker API reference See skills/photo-library-ref.md PhotoKit + Swift 6 strict concurrency, nonisolated observer, performChanges isolation, dispatchassertqueuefail See axiom-concurrency (skills/isolation-inheritance-diag.md) Audio, AVFoundation, spatial audio See skills/avfoundation-ref.md Video write/export/playback, sample-buffer engine, resumable export, Apple Log 2, iOS 27 deprecations (OS27) See skills/avfoundation-video-ref.md Audio recognition, ShazamKit See skills/shazamkit.md ShazamKit API reference See skills/shazamkit-ref.md On-device music analysis (key, tempo, structure, loudness), MusicUnderstanding (OS27) See skills/music-understanding.md On-device face grouping (cluster faces into people across a library), video highlights/key frames, MediaIntelligence (OS27) See skills/media-intelligence.md Haptic feedback, Core Haptics See skills/haptic …
