simplecadapi skillA

simplecadapi is agent-read markdown (skill) from nijingzhe/simplecadapi: Build, assemble, inspect, reconstruct, and export parametric CAD models with the SimpleCADAPI Python SDK. Use for SimpleCAD geometry modeling, constrained sketches, parts and assemblies, standard gears and bearings, STEP/BREP inspection and reconstruction, vector-PDF drawing reconstruction, durable product packages, model JSON replay, and CAD backend translation..

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 nijingzhe/simplecadapi/simplecadapi@v2.1.3
Exact content
mdr add nijingzhe/simplecadapi/simplecadapi@sha256:4ba5f264fd996ffd

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.
