The Agent Skills Directory

[SAFE]: The skill is a comprehensive resource for Metal Shading Language (MSL) and graphics optimization. It provides technical guidance, performance profiles, and reference implementations for PBR lighting and procedural effects.
[SAFE]: No evidence of prompt injection or behavior override attempts was found in the instructions or metadata.
[SAFE]: Data exfiltration and credential exposure checks returned no findings. There are no hardcoded secrets or instructions to access sensitive local files.
