camera-auditor

Scans Swift code for camera, video, and audio capture issues including deprecated APIs, missing interruption handlers, threading violations, and permission anti-patterns.

How to Use This Agent

Natural language (automatic triggering):

• "Can you check my camera code for issues?"
• "Audit my capture implementation"
• "Is my camera code following best practices?"
• "Check for deprecated camera APIs"
• "Review my AVFoundation capture code"

Explicit command:

/axiom:audit camera

What It Does

Critical Issues

• Main thread session work — startRunning() on main thread causes UI freezes
• Missing purpose strings — Camera/microphone usage without Info.plist keys causes App Store rejection

High Priority

• Deprecated videoOrientation — Use RotationCoordinator instead (iOS 17+)
• Missing interruption handling — No observers for phone calls, multitasking
• UIImagePickerController for photos — Replace with PHPicker or PhotosPicker

Medium Priority

• Over-requesting photo library access — PHPicker doesn't need permission
• Missing photo quality settings — Default .quality is slow for social apps
• AVAudioSession category mismatch — Wrong category prevents recording

Low Priority

• Configuration without block — Missing beginConfiguration/commitConfiguration
• Synchronous photo loading — Blocking main thread during image load

Example Output

## Audit Summary

- **CRITICAL**: 2 issues
- **HIGH**: 3 issues
- **MEDIUM**: 1 issue

**Top priority fixes**:
1. Move startRunning() to session queue (UI freeze risk)
2. Add AVCaptureSession interruption observers
3. Replace deprecated videoOrientation with RotationCoordinator
