A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
A modern Mac app is SwiftUI-first with AppKit as the escape hatch for advanced window management, custom NSView work, and APIs SwiftUI doesn't cover. The Mac-specific design vocabulary — toolbars, sidebars, inspectors, multiple windows, menu bar commands, drag and drop — must feel native. Cross-platform code (with iOS) belongs in a shared SPM target; platform-specific UI lives in a Mac-only target.
