What problem does it solve? AI coding agents frequently write incorrect Liquid Glass code for macOS 26 because the API shipped after most training data, producing hallucinated modifiers, glass-on-glass stacking, missing availability gates, and misplaced glass on content instead of navigation chrome. ## Core Features & Use Cases - 18-rule defect index: Detects hallucinated symbols like .glassBackground() and LiquidGlassView, visionOS-only APIs on Mac targets, wrong-arm #available(iOS 26) gates, glass-on-glass stacking, and missing GlassEffectContainer grouping. - Hybrid lint engine: Runs tier-1 ripgrep tells plus tier-2 ast-grep structural rules that express containment and gate scope, emitting unified JSON and SARIF with CI exit codes. - Evidence-grounded verification: Cross-checks uncertain symbols against a corpus of 1,857 shipping macOS apps via the swiftui-ctx CLI and Apple documentation via Sosumi before reporting findings. - Safe auto-fixes: Applies mechanical corrections (hallucinated names, wrong-arm gates, leftover toolbar overrides) under a fix-safety protocol with one commit per finding. - Use Case: Point the audit at a macOS SwiftUI project targeting macOS 15+ that an AI assistant wrote glass code for, and receive per-finding reports with severity, citations, and verified fixes. ## Quick Start Audit the SwiftUI sources in this macOS project for Liquid Glass correctness and fix any hallucinated glass APIs you find.
