The Agent Skills Directory

[COMMAND_EXECUTION]: The skill provides numerous command-line instructions for the agent to execute, primarily using @gltf-transform/cli and gltfpack. These are standard tools for 3D asset optimization.
The commands include geometry processing (weld, quantize, meshopt, draco) and texture processing (resize, webp, etc1s, uastc).
The troubleshooting section mentions xattr -d com.apple.quarantine ./gltfpack, which is a standard procedure on macOS to allow a downloaded binary to run, and does not constitute privilege escalation in this context.
[EXTERNAL_DOWNLOADS]: The skill references several external resources, all of which are established and reputable.
It utilizes npx to run tools from the npm registry.
The scripts/package.json file lists standard dependencies such as @gltf-transform/core, draco3dgltf, and meshoptimizer.
Remote documentation and decoder sources point to trusted domains including khronos.org, google.com (Google CDN for Draco decoders), and babylonjs.com (Babylon CDN).
The skill script scripts/glb-audit.sh performs an npm install to set up its local environment, which is standard behavior for Node.js-based tooling.
[DATA_HANDLING]: The skill is designed to audit and process user-supplied 3D models. It includes a custom auditing script (scripts/glb-audit.mjs) that calculates file metrics (triangles, draw calls, VRAM) locally without exfiltrating data to external servers.
