text-to-cad is a collection of agent workflows for creating, examining, finding, preparing, and transferring CAD, engineering, manufacturing, and robot-description files. It is for agents working with mechanical design, fabrication, simulation, and robotics projects. Catalogue skills, instructions, and a plugin implement these workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00087 | $0.04498 |
| Opus 5.5 | $0.00035 | $0.01799 |
| Sonnet 5.5 | $0.00017 | $0.00900 |
| Haiku 4.5 | $0.00009 | $0.00450 |
Grade A, and why
dxf scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 381 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DXF generation and validation
Provenance: maintained in earthtojake/text-to-cad. Use the installed local skill files as the runtime source of truth; the repository link is only for provenance and release review.
Setup
Run cadgen through uv, so this skill's commands share one installation, and its warm build daemon, with the CAD app's server:
cadgenbelow meansuvx --no-config --managed-python --python 3.13 --from cadgen==0.7.26 cadgenpythonbelow meansuvx --no-config --managed-python --python 3.13 --from cadgen==0.7.26 python
The first run downloads that installation and the first snapshot its headless browser; later runs reuse both.
cadgen doctor <skill-dir> reports the installation in use and checks that it is
the one this skill pins, and that the CAD kernel loads; use it for installation or
kernel load errors.
Drawings are build123d geometry, so a drawing build loads the CAD kernel like a
STEP build does (~2.5s cold; the warm daemon absorbs it on re-runs).
cadgen dxf snapshot needs no Node at all: it flattens the drawing with ezdxf
(which arrives with cadgen) and paints it in the bundled headless browser.
Purpose
Create or modify 2D DXF drawings from natural-language requirements or from CAD
geometry, generate validated drawing artifacts, and return checked outputs. A
DXF drawing's source of truth is a Python file named <name>.py defining one
parameterless @dxf model function.
A drawing is a model. It has the same wrapper, record, freshness gate and
build job a @step part has; its one output is the .dxf file; it has no
geometry tree (nothing links to a drawing). Every run writes the sibling
<name>.dxf (or the out= the decorator names); an unchanged source is a
no-op; a drawing that calls a part model — bracket() inside its body — is
stale whenever that part's GEOMETRY changes and current when it does not;
cadgen store why <drawing>.py explains the verdict; --force rebuilds it
anyway. The CAD Viewer and dxf snapshot read the .dxf file itself, so the
file you hand a cutting service, the file the viewer draws and the file a
snapshot renders are one and the same.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dxf is a skill published in the GitHub repository earthtojake/text-to-cad (23,132 stars, last pushed today), licensed MIT. It adds 87 tokens to every session and 4,498 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
