## What it does

Capso is a native macOS app for screenshots and screen recording, written in Swift 6.0 with SwiftUI and targeting macOS 15.0+. Its modular layout is the draw for developers: eight separate SPM packages, each embeddable on its own.

The skill walks through the project architecture, building from source, and the package APIs. `CaptureKit` handles area, window and fullscreen capture. `RecordingKit` covers audio, format and quality settings. `CameraKit` adds a webcam overlay, `AnnotationKit` gives you shapes, text and undo, and `OCRKit` wraps the Vision framework. Code samples come with each.

Building from source needs Xcode 16+, macOS 15.0+ and XcodeGen — without it `xcodegen generate` fails and the project never opens. The pre-built app installs through Homebrew or a signed DMG.
