3d-in-readme skillA

3d-in-readme is agent-read markdown (skill) from nirholas/three.ws: Embed an interactive 3D model in a GitHub README, issue, PR, or any markdown file. Use when the user wants to add, embed, or show a 3D model, avatar, mesh, STL, GLB, or 3D print in markdown or a README - "add a 3D model to my README", "embed this GLB", "show the part in the issue". Converts GLB/glTF/OBJ/STL to the ASCII STL block GitHub renders natively, simplified to fit GitHub's 512 KB markdown limit..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add nirholas/three.ws/3d-in-readme@git:20260713.8b8c13e
Exact content
mdr add nirholas/three.ws/3d-in-readme@sha256:3e6da7569649fcc2

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
