The Agent Skills Directory

[NO_CODE]: The skill consists entirely of Markdown reference files and instructions. There are no scripts, binaries, or configuration files that execute code on the host system or within the agent environment.
[EXTERNAL_DOWNLOADS]: The skill references external URLs for documentation and attribution purposes. These URLs point to official Apple Developer domains (developer.apple.com) and the author's verified website (raintree.technology). No automated downloads or remote script executions are triggered.
[SAFE]: No malicious patterns such as prompt injection, obfuscation, or data exfiltration were detected. The skill's behavior is purely informational and aligns with its stated purpose of providing design foundations for Apple platforms.
