Expert guide to Capso: building from source, SPM package architecture, using CaptureKit/AnnotationKit/OCRKit, and contributing to the macOS screenshot/recording
This skill provides practical guidance for working with Capso — an open-source macOS screenshot and screen recording app. It covers installing prebuilt builds, building from source with XcodeGen, the modular SPM-based project layout, and package-level APIs (CaptureKit, RecordingKit, AnnotationKit, OCRKit, ExportKit). The skill is designed to help developers embed Capso packages, run package tests, and resolve common build or permission issues.
Use when you need to add screenshot or screen-recording features to a macOS app, build or contribute to Capso, integrate CaptureKit/AnnotationKit into your project, or debug common macOS entitlement and permission problems. It is not intended for non-macOS platforms.
Useful for developer-focused agents and code assistants that work with Swift/Xcode projects (agents that can read Swift code, run swift test, and edit Xcode project files).
Purely documentation skill for Capso, an open-source macOS screenshot/screen recording app built with Swift 6 and SwiftUI. No bundled scripts — the skill provides detailed API examples for 8 SPM packages (CaptureKit, AnnotationKit, OCRKit, etc.) and installation/build instructions. Well-structured reference with no security concerns since there's no executable code.
Documentation-only skill with no scripts. SKILL.md is comprehensive and well-organized. The BSL 1.1 license is worth noting — it restricts competitive use until 2029 when it auto-converts to Apache 2.0. No security risks since there is no executable content.
