// swift-tools-version:5.9
//
// gen-accessors-tool — SwiftPM tool that reads an app's Swift source via
// swift-syntax, finds @Observable classes with `// @Snapshotable`-marked
// fields, and emits StateAccessor.swift for each one.
//
// First build is 2-5 min on a cold machine (swift-syntax compile chain).
// Subsequent runs are content-hash-cached and finish in ~50ms.
//
// Invocation:
//   swift run --package-path ios-qa/scripts/gen-accessors-tool \
//     gen-accessors --input <swift-source-dir> [--output <out-dir>]
