The Agent Skills Directory

[SAFE]: The skill is a set of technical instructions and a reference implementation for 3D rendering. A thorough analysis of the provided code snippets and the demo HTML file revealed no malicious patterns such as prompt injection, data exfiltration, or obfuscation.
[DYNAMIC_EXECUTION]: The skill demonstrates the use of Three.js onBeforeCompile to inject custom GLSL code into shaders. This is a standard and expected technique for achieving high-performance visual effects (like the described instanced grass) and does not involve the execution of untrusted user input.
[EXTERNAL_DOWNLOADS]: The demo/index.html file references a local dependency assets/three.min.js. It does not attempt to load scripts from remote or unverifiable sources.
[INDIRECT_PROMPT_INJECTION]: While the skill is designed to process a user's "subject" to generate a surrounding environment, it acts as a code-generation blueprint rather than an execution engine with sensitive capabilities. The risk of indirect injection is minimal and handled by standard model constraints.
