text-to-cad

text-to-cad is a library of agent skills for generating, inspecting, sourcing, slicing, and handing off CAD and robot-description artifacts from local project files.

URDF

SRDF / MoveIt2

🧰 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 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
DfAM Check	Measures mesh printability per process: wall thickness, overhangs, support volume, and build orientation.	skills/dfam-check
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 text-to-cad with the Skills CLI:

npx skills add earthtojake/text-to-cad

This is the preferred installation path. It installs the individual skills directly for supported agents.

Use the same command to update. add re-fetches the package and overwrites what is already installed, so it both refreshes existing skills and installs any skill added in a newer release. npx skills update only refreshes skills already in your lockfile, so it silently misses new ones — which matters here, because releases do add skills.

Neither command removes a skill that was retired upstream; drop one with npx skills remove <skill> if you need to.

(npx skills install … still works — it is an undocumented alias for add.)

Plugins

Provider-native plugin installs are also available for Codex, Claude Code, and Grok Build:

# Codex (requires Codex 0.142.0 or newer)
codex plugin marketplace add earthtojake/text-to-cad
codex plugin add cad@text-to-cad

Codex 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-cad

Grok Build uses the existing .claude-plugin/marketplace.json; there is no separate Grok plugin manifest.

# Grok Build
grok plugin install earthtojake/text-to-cad --trust
grok plugin enable cad

Restart 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.

Development happens from the develop branch; open PRs against develop, not main. For local contribution workflow, skill linking, and validation guidance, see CONTRIBUTING.md.
