procedural-geometry SKILL.md skillA
procedural-geometry from wolffe/three.js-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wolffe/three.js-skills/procedural-geometry@git:20261031.845cf45Pins git:20261031.845cf45 in mdr.lock. Pin the fingerprint instead.

Create realistic procedural Three.js geometry for large engineered environments. Use for trains, tracks, stations, buildings, bridges, pipes, infrastructure, vehicles, structures, and other 3D geometry generated from code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Procedural Geometry for Engineered Environments Target: Three.js 0.187.0, WebGPU renderer (`three/webgpu`) and TSL node materials (`three/tsl`); WebGPU only, no WebGL fallback, no GLSL strings. ## Purpose Create realistic, high-quality 3D geometry for engineered environments (vehicles, tracks, stations, buildings, bridges, pipes and infrastructure) using Three.js procedural geometry. All geometry must be generated procedurally from JavaScript and Three.js geometry. Do not use GLB, GLTF, FBX, OBJ, CAD imports, downloaded meshes, or other pre-made 3D assets unless explicitly requested. The objective is **believable manufactured geometry**, not generic "sci-fi" decoration and not low-poly abstraction. The environment should feel like a functioning, enormous engineered place designed for humans. --- # Core Modelling Vocabulary …

How to install
mdr add wolffe/three.js-skills/procedural-geometry@sha256:02778a4f8acd1146The line at the top of this page pins the label git:20261031.845cf45, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
