Use when working with DESIGN:OS 3D Blender Agent — Parametric 3D mechanical parts generator, headless Blender Python (`bpy`) pipeline, and embedded Three.js CAD showcase engine.
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.

# DESIGN:OS 3D Blender Agent (`design-os-3d-blender`) Generate dimensionally accurate gears, enclosures, drone frames, and exploded mechanical assemblies from plain-English specs or JSON parameters, complete with glTF/STL exports and interactive browser inspection. ## When to Use Activate this skill when the user asks to: - `"Generate a parametric 24-tooth helical gear and mounting bracket in headless Blender and export glTF + STL artifacts."` - `"Build an interactive Three.js CAD viewer page with exploded-view scrubbing, wireframe toggle, and orthographic camera presets."` - `"Audit the exported mesh topology for non-manifold edges, zero-area faces, and bounding-box dimensional tolerances."` ## Progressive Disclosure Routing (`What loads when`) 1. **Always Loaded**: `skills/design-os-3d-blender/SKILL.md` (this router — keeps context lean). 2. **On Demand — Prompt Recipes**: Load `docs/cookbook.md` when selecting multi-step workflows or copy-paste prompt templates. 3. **On Demand — Diagnostics**: Load `commands/doctor.md` or run `python3 scripts/self_check.py` when verifying installation or troubleshooting. …

How to install
mdr add jangtrinh/design-os-3d-blender/design-os-3d-blender@sha256:8623045b8b0ea1feThe line at the top of this page pins the label git:20261014.881a4c8, 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.
