# AVFAudio Session Workflow ## Purpose Guide Apple app audio-session design and repair. This skill owns the app-level audio intent boundary: what the app tells the system it wants to do with audio, when it activates that intent, how it responds to interruption and route changes, how it preserves typed AVFAudio policy surfaces, and how it explains failures. It is not the audio-engine graph workflow, not the AVFoundation media-pipeline workflow, not the Core Media timing workflow, and not the Xcode execution workflow. ## When To Use - Use this skill when configuring or repairing `AVAudioSession`, `AVAudioApplication`, `AVAudioApplication.requestRecordPermission`, recording permission, categories, modes, options, `AVAudioSession.RouteSharingPolicy`, activation, deactivation, interruptions, route changes, Bluetooth, AirPlay, speaker routing, or capture-session audio-session behavior. - Use this skill when existing audio code plays from the wrong route, fails silently, captures silence, interrupts other audio incorrectly, fails around calls, ignores headphones disconnects, or logs vague audio errors. - Recommend `avaudio-engine-workflow` when the primary issue is an `AVAudioEngine` graph, node connection, tap, render callback, manual rendering, or format conversion. - Recommend `avfoundation-media-pipeline-workflow` when the primary issue is capture, playback, media assets, readers, writers, export, or sample-buffer append policy. - Recommend `coremedia-timing-samplebuffer-wo
