A skills library for CAD, robotics, and hardware design agents
CAD Skills
CAD Skills is a library of agent skills for generating, inspecting, sourcing, slicing, and handing off CAD and robot-description artifacts from local project files.
🧰 Skills
Install the library to give agents focused workflows for CAD, fabrication, robot description files, simulation, and local review.
| Skill | Summary | Source |
|---|---|---|
| CAD | Creates and edits CAD models from plain-language or image requests, with STEP as the main output along with options to export to STL, 3MF and GLB. | skills/cad |
| CAD Viewer | Shows local browser previews for CAD, G-code, and robot files. | skills/cad-viewer |
| step.parts | Finds off-the-shelf STEP parts like screws, bearings, motors, and connectors. | skills/step-parts |
| DXF | Creates 2D DXF drawings like profiles, templates, gaskets, and cut layouts from Python sources or CAD geometry. | skills/dxf |
| URDF | Writes robot structure files with links, joints, limits, inertials, and meshes. | skills/urdf |
| SRDF | Adds MoveIt planning groups, end effectors, poses, and collision rules to a URDF. | skills/srdf |
| SDF | Creates simulator models and worlds with frames, physics, sensors, and lights. | skills/sdf |
| SendCutSend | Checks DXF and STEP files before upload to SendCutSend. | skills/sendcutsend |
| G-code | Slices supported mesh files into validated, printer-profiled FDM .gcode with real slicer CLIs. |
skills/gcode |
| Bambu Labs | Dry-runs, uploads, and cautiously starts local Bambu Lab print jobs from validated .gcode. |
skills/bambu-labs |
| Implicit CAD | Creates browser-native implicit CAD models using GLSL signed-distance fields and CAD Viewer raymarch rendering. Experimental. | skills/implicit-cad |
💻 Installation
For production use, install or clone from main; that branch contains the
generated skill outputs needed by provider installers.
Skills
Install CAD Skills with the Skills CLI:
npx skills install earthtojake/text-to-cadThis is the preferred installation path. It installs the individual skills directly for supported agents.
Plugins
Provider-native plugin installs are also available for Codex and Claude Code:
# Codex (requires Codex 0.142.0 or newer)
codex plugin marketplace add earthtojake/text-to-cad
codex plugin add cad@text-to-cadCodex resolves this repository-root plugin only from 0.142.0 onward. On older
versions the plugin is skipped silently and never appears in codex plugin list;
upgrade with npm install -g @openai/codex@latest.
# Claude Code
claude plugin marketplace add earthtojake/text-to-cad
claude plugin install cad@text-to-cadRestart your agent if newly installed skills do not appear. For local
development, branch from develop, open PRs against develop, and use the symlink
workflow in CONTRIBUTING.md.

🧪 Benchmarks
The repo stores heavyweight assets in assets/** and benchmarks/** through Git LFS and excludes those trees from default LFS pulls so lightweight clones do not fetch GIF assets. Benchmark markdown remains normal Git for readable diffs. To hydrate only the benchmark assets locally, run:
git lfs pull --include="benchmarks/**"| # | Target | Prompt | Output |
|---|---|---|---|
| 1 | Rectangular calibration block with four holes | Create a centered 100 x 60 x 20 mm block with four 8 mm vertical through-holes. Add only a 2 mm chamfer on the top outer perimeter. |  |
| 2 | Circular flange with bolt-hole pattern | Create an 80 mm diameter, 10 mm thick circular flange with a 30 mm central through-bore. Add six 6 mm through-holes on a 60 mm bolt circle and fillet the outside circular edges. |  |
| 3 | L-bracket with gussets and two hole directions | Create an L-bracket from a base plate and rear vertical plate. Add vertical base holes, horizontal back-plate holes, two triangular gussets, and a filleted base/back transition. |  |
| 4 | Stepped shaft with keyway | Create a 120 mm shaft along X with 20/30/20 mm diameter stepped sections. Add end chamfers and a shallow rectangular keyway on top of the middle section. |  |
| 5 | Open-top electronics enclosure with bosses | Create a hollow open-top enclosure with 3 mm walls and floor. Add four internal standoffs with centered blind holes and 2 mm outside vertical corner fillets. |  |
| 6 | Aerospace-style clevis bracket with lightening cutouts | Create a symmetric clevis bracket with a base plate, two rounded lugs, base mounting holes, and a horizontal lug bore. Add triangular lightening cutouts, reinforcing ribs, and rounded transitions. |  |
| 7 | Radial-engine-style cylinder with cooling fins | Create a vertical engine-cylinder form with a central barrel, 12 cooling fins, a base flange, and a top cap. Add a 35 degree angled spark-plug boss with a coaxial through-hole. |  |
| 8 | Centrifugal impeller with backward-curved blades | Create a centrifugal impeller with a backplate, hub, and through-bore. Add 12 fused backward-curved blades sweeping about 45 degrees from root to tip. |  |
| 9 | Spiral staircase with helical handrail | Create a miniature spiral staircase with a central column, base disk, and 20 rising wedge treads. Add a one-revolution helical handrail and vertical balusters at the tread outer ends. |  |
| 10 | Simplified planetary gear stage | Create a flat planetary gear assembly with separate sun, planet, ring, carrier, and pin bodies. Use simplified trapezoidal teeth and place three planets around the sun on a 42 mm radius circle. |  |
