Partial A macOS instant search app is buildable, but a fast, correct, low-latency index with FSEvents watching and native AppKit UI through Rust bindings is systems-level work that vibe coding will struggle to get right alone.
What it would actually take: The stack would be a Rust inverted index with a persistent on-disk format, FSEvents-based incremental updates, and a SwiftUI or AppKit front end connected through UniFFI. The hard parts are keeping the index consistent under heavy filesystem churn and tuning sub-10ms query latency, which requires experience with macOS internals and low-level performance work.
