gen SKILL.md skillA
gen from partcad/partcad is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add partcad/partcad/gen@git:20261106.8c298cbPins git:20261106.8c298cb in mdr.lock. Pin the fingerprint instead.

Generate PartCAD geometry from a description, automatically deciding whether the request is a single part, a multi-part assembly, a scene (an arrangement of objects - a room, an interior, a workcell, a world), or a 2D sketch and following the matching flow. Use for /pc:gen or when the user asks to generate, create, or model something in PartCAD without saying whether it is a part, an assembly, a scene, or a sketch.
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
# pc:gen Entry point for PartCAD generation when the user has not said whether they want a single **part**, an **assembly**, a **scene**, or a 2D **sketch**. The text after the command (`$ARGUMENTS`) is the description of what to build. Decide which it is, tell the user your choice, then follow that flow — passing the same description through. ## Decide: part, assembly, scene, or sketch? - **Part** → `/pc:gen-part`. One continuous piece of 3D geometry — a bracket, a gear, a housing, a knob. Modeled as a single script, even when intricate. - **Assembly** → `/pc:gen-assembly`. Several distinct 3D components that fit or move relative to each other — a gearbox, a robot arm, a body with a lid, anything joined by fasteners. - **Scene** → `/pc:gen-scene`. Objects arranged where they stand rather than put together into a product — a room, a building interior, an office floor, a workcell, a table laid out, a world to simulate something in. - **Sketch** → `/pc:gen-sketch`. A 2D profile, outline, or blueprint — a gasket shape, a plate outline, a cross-section to be extruded later. Heuristics: - "2D", "profile", "outline", "sketch", "cross-section", "blueprint", "trace …

How to install
mdr add partcad/partcad/gen@sha256:f8b2d99c78dae860The line at the top of this page pins the label git:20261106.8c298cb, 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.
