cad

Dry-run, upload, and cautiously initiate local Bambu Lab print jobs from validated plain `.gcode`, using Bambu LAN FTPS/MQTT handoffs.

Start or reuse CAD Viewer and return review links for explicit CAD, robot-description, and G-code files. Use when visually reviewing `.step`, `.stp`, `.glb`, `.stl`, `.3mf`, `.gcode`, `.dxf`, `.urdf`, `.srdf`, or `.sdf` files, especially when handed off from CAD, G-code, URDF, SRDF, or SDF generation skills.

Create, modify, inspect, and validate STEP-first build123d/Python CAD parts and assemblies. Use for natural-language CAD specs, STEP/STP generation or direct inspection, build123d source, build123d source-level joints, @cad references, geometry facts, measurements, mating deltas, CAD Viewer handoffs, snapshots, and secondary DXF/STL/3MF/native GLB outputs from CAD geometry.

Generate, inspect, dry-run, and statically validate plain FDM `.gcode` from 3D mesh files by orchestrating real slicer CLIs. Use when Codex needs to slice `.stl`, `.obj`, unsliced `.3mf`, `.ply`, `.glb`, or `.gltf` into printer-profiled G-code, discover local slicer backends, inspect whether a mesh is slice-ready, or validate generated G-code before any printer-specific handoff.

SDFormat/SDF model and world generation, validation, and simulator handoff. Use for `.sdf` files, SDFormat XML, Python `gen_sdf()` sources, models, worlds, links, joints, poses, frames, inertials, visual/collision geometry, mesh URIs, sensors, lights, physics, plugins, includes, Gazebo, static SDF review, or simulator-specific metadata. Do not use for signed-distance-field geometry.
