SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyobjc-framework-Quartz, and includes scripts (resource) components.

What problem does it solve?

Claude can capture screenshots of a target window or the entire screen to PNG files, providing a reliable visual record for validation, debugging, and documentation.

Core Features & Use Cases
