SmartTrim macOS menu bar utility

System-integration slice: macOS menu bar UI, clipboard healing, global hotkey, launch-at-login.

Methodology

This evaluation tests macOS system integration with Swift 6 strict concurrency. The model must implement a menu bar utility with clipboard monitoring, text healing heuristics, global hotkey registration, and launch-at-login functionality. SwiftUI MenuBarExtra patterns are critical.

Spec: Swift 6 LSUIElement MenuBarExtra with TextHealer heuristic, clipboard monitor, tests, hotkey, login item.

KEY TAKEAWAYS

GPT-5.1 wins (92), Claude/xhigh tied (88), medium (85); Gemini lags (67) with ghost indentation.
Swift 6 strict concurrency + SwiftUI tractable; heuristics still need human-tuned edges.
