audit-foundation-models

Scan Foundation Models / Apple Intelligence integration code for issues that crash on unsupported devices, freeze the UI, or mishandle guardrail responses.

What This Command Does

Launches the foundation-models-auditor agent to flag the most common mistakes when integrating on-device language models — missing availability gates, blocking calls on the main actor, and brittle parsing of structured output.

What It Checks

1. Missing availability checks – LanguageModelSession use without isAvailable or device-capability gating
2. Main thread blocking – synchronous model calls on @MainActor, freezing the UI during inference
3. Manual JSON parsing – JSONDecoder against model output where @Generable would give compiler-checked structure
4. Missing error handling – no recovery for .guardrailViolation, .unsupportedLanguage, .assetsUnavailable
5. Session lifecycle – sessions created per-message instead of reused, or held across app states without checkpointing
