The Agent Skills Directory

[SAFE]: The skill instructions in SKILL.md are focused on legitimate CSS implementation of mask-image and -webkit-mask-image for visual effects.
[SAFE]: The demo/index.html file provides a functional reference implementation using standard web technologies. While the inline JavaScript contains complex logic for a Canvas animation, it is restricted to mathematical drawing operations and does not attempt any network requests, sensitive file access, or command execution.
[SAFE]: No prompt injection patterns, obfuscated strings, or suspicious metadata were detected in the skill files or demo prompts.
