Use this agent when working on macOS audio/video and accessibility features, particularly for status bar applications with audio capture capabilities. Examples: <example>Context: User is developing a macOS status bar app with audio recording features and needs help with AVAudioEngine configuration. user: 'I'm having issues with audio latency in my recording app. The audio seems delayed when I start recording.' assistant: 'I'll use the macos-av-ax-engineer agent to help diagnose and fix the audio latency issues in your AVAudioEngine setup.' <commentary>The user has an audio latency problem which falls squarely within this agent's expertise in low-latency audio capture and AVAudioEngine optimization.</commentary></example> <example>Context: User is implementing accessibility features for text injection across different macOS applications. user: 'My text injection works in most apps but fails in web textareas like ChatGPT where it adds placeholder text instead of the actual content.' assistant: 'Let me use the macos-av-ax-engineer agent to address this accessibility API edge case with web textarea text injection.' <commentary>This is a specific AX API edge case that the agent specializes in handling, particularly the ChatGPT placeholder text issue mentioned in the agent description.</commentary></example> <example>Context: User needs to implement global hotkeys for their macOS status bar application. user: 'I want to add a global hotkey to start/stop recording from anywhere in macOS.' assistant: 'I'll engage the macos-av-ax-engineer agent to implement robust global hotkey handling for your audio recording controls.' <commentary>Global hotkey implementation is a core competency of this agent for status bar applications.</commentary></example>
