# How to Install earthtojake/text-to-cad: Three Methods for CAD Generation Skills > Install earthtojake/text-to-cad easily with three methods: Skills CLI, platform plugins, or direct repository cloning. Master CAD generation skills today. - Repository: [earthtojake/text-to-cad](https://github.com/earthtojake/text-to-cad) - Tags: how-to-guide - Published: 2026-09-13 --- **You can install earthtojake/text-to-cad via the universal Skills CLI (`npx skills add earthtojake/text-to-cad`), as a platform-specific plugin for Codex, Claude Code, or Grok Build, or by cloning the repository for Python development.** The `earthtojake/text-to-cad` repository provides agent skills that generate CAD models, URDF robot descriptions, and simulation artifacts. Installing these capabilities depends on whether you are adding skills to an existing agent runtime or contributing to the core engine locally. ## Method 1: Install via Skills CLI (Recommended) The **Skills CLI** offers the fastest path to deploy text-to-cad capabilities. This universal installer fetches skill definitions directly from the repository and registers them with your agent without manual configuration. To install all text-to-cad skills, run: ```bash npx skills add earthtojake/text-to-cad ``` The command downloads the skill definitions from [`skills/cad/SKILL.md`](https://github.com/earthtojake/text-to-cad/blob/main/skills/cad/SKILL.md) and [`skills/urdf/SKILL.md`](https://github.com/earthtojake/text-to-cad/blob/main/skills/urdf/SKILL.md), making them immediately available to your agent. To update existing skills to the latest version, execute the same command again. The CLI automatically re-fetches and overwrites any existing skill files. ## Method 2: Install as an Agent Plugin For users running specific agent platforms, the repository provides native plugin manifests. Each platform offers a one-line installation command that registers the `text-to-cad` plugin with the agent runtime. ### Codex Plugin Installation Requires Codex version 0.142.0 or higher: ```bash codex plugin marketplace add earthtojake/text-to-cad codex plugin add cad@text-to-cad ``` ### Claude Code Plugin Installation ```bash claude plugin marketplace add earthtojake/text-to-cad claude plugin install cad@text-to-cad ``` ### Grok Build Plugin Installation ```bash grok plugin install earthtojake/text-to-cad --trust grok plugin enable cad ``` ## Method 3: Clone and Install for Development Contributors and advanced users should clone the repository to access the full source code and validation suite. This method requires **Python 3.11** or newer. First, clone the repository and navigate to the project root: ```bash git clone https://github.com/earthtojake/text-to-cad.git cd text-to-cad ``` Install the development dependencies specified in [`requirements-dev.txt`](https://github.com/earthtojake/text-to-cad/blob/main/requirements-dev.txt): ```bash pip install -r requirements-dev.txt ``` Verify the installation by executing the test driver: ```bash ./scripts/test/test.sh ``` This script validates the integration between the skill definitions and the core engine. ## Understanding the Core Engine (cadgen) All three installation methods ultimately rely on the **cadgen** distribution located in `packages/cadgen/`. According to [`packages/cadgen/README.md`](https://github.com/earthtojake/text-to-cad/blob/main/packages/cadgen/README.md), this package contains the core generation engine, a bundled JavaScript runtime, and the CAD Viewer server. The `cadgen` package is version-pinned in each skill's [`requirements.txt`](https://github.com/earthtojake/text-to-cad/blob/main/requirements.txt) file, ensuring compatibility between the skills and the underlying generation runtime. When installing via CLI or plugins, the system automatically resolves these dependencies without manual intervention. ## Summary - **Install earthtojake/text-to-cad** instantly using `npx skills add earthtojake/text-to-cad` for universal agent support - Platform-specific plugins are available for Codex (≥0.142.0), Claude Code, and Grok Build using their respective CLI commands - Development installations require cloning the repo, installing dependencies from [`requirements-dev.txt`](https://github.com/earthtojake/text-to-cad/blob/main/requirements-dev.txt), and running [`./scripts/test/test.sh`](https://github.com/earthtojake/text-to-cad/blob/main/./scripts/test/test.sh) - The `cadgen` package in `packages/cadgen/` provides the core engine that powers CAD and URDF generation skills ## Frequently Asked Questions ### How do I update text-to-cad skills after installation? Run the same installation command used initially. For CLI installations, execute `npx skills add earthtojake/text-to-cad` again to re-fetch the latest skill definitions. Plugin users should reference their platform's native update mechanism to refresh the `cad@text-to-cad` registration. ### What Python version is required for development? The repository requires **Python 3.11** or newer when installing from source. This version requirement is enforced in [`requirements-dev.txt`](https://github.com/earthtojake/text-to-cad/blob/main/requirements-dev.txt) to ensure compatibility with the `cadgen` engine bindings and asynchronous runtime features. ### Where is the core CAD generation logic located? The core engine resides in `packages/cadgen/` as documented in [`packages/cadgen/README.md`](https://github.com/earthtojake/text-to-cad/blob/main/packages/cadgen/README.md). This directory contains the bundled JavaScript runtime and CAD Viewer server that processes generation requests from the skill definitions in `skills/cad/` and `skills/urdf/`. ### Can I install individual skills instead of the entire repository? Yes. While `npx skills add earthtojake/text-to-cad` fetches all available skills, the modular structure allows agent platforms to load specific skill definitions selectively. Each skill directory contains a [`SKILL.md`](https://github.com/earthtojake/text-to-cad/blob/main/SKILL.md) manifest that defines its parameters and can be targeted individually by advanced agent configurations.
