A local workflow for generating 3D computer-aided design models as STEP, GLB, STL, or 3MF files. It also supports manufacturing checks, engineering drawings, and connections to fabrication services.

Use it to create 3D models, check whether designs can be manufactured, make engineering drawings, and send designs to 3D printing, sheet-metal, or CNC services.

It brings model creation and production preparation into a text-driven coding-agent workflow instead of requiring each task to be handled separately.

text-to-cad — Plugin for Gemini CLI by earthtojake

About the project

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.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/earthtojake/text-to-cad

Made for: Gemini CLI.

Security

Grade A, and why

text-to-cad 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 4d ago.

The scan reads gemini-extension.json. This mod also ships 56 executable files (scripts/bench/cadgen-performance/agent_edits.py, scripts/bench/cadgen-performance/common.py, scripts/bench/cadgen-performance/warm_build.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

60 files beside gemini-extension.json 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.

Changes

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.

text-to-cad is a plugin published in the GitHub repository earthtojake/text-to-cad (20,702 stars, last pushed today), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-10-06.
