Get started

Get started with Claude Code

Download the Claude Code plugin preview, install it locally and build your first app.

Verified 16 October 2026

Use Claude Code as your starting point. The Unstoppable Stack plugin brings 19 skills and reference routers into your assistant; the CLI handles app scaffolding.

Local plugin preview

This download contains skills and references for Claude and Codex. It is a local installation preview, not a public marketplace listing. Native package parsing has been checked; full session activation and end-to-end assistant workflows remain under evaluation.

Check your assistant and install the matching CLI

Start with Claude Code installed and signed in, plus Node.js 22.17 or newer and npm. This plugin requires CLI 0.4.0-beta.1. The matching candidate is not on npm yet; use this pinned source build in a new folder. npm 0.3.0 does not supply the maintained workflow. The commands below use a macOS/Linux shell and a user-writable npm prefix.

bash

$ claude --version
claude plugin --help
git clone https://github.com/unstoppable-stack/unstoppable-dev.git unstoppable-cli-source
cd unstoppable-cli-source
git checkout 121cabca1ed2978f98ff1795cc6b87401889be9e
cd packages/cli
npm ci --ignore-scripts
mkdir -p ../../cli-artifacts
npm pack --pack-destination ../../cli-artifacts
npm install --global --prefix "$HOME/.local" ../../cli-artifacts/unstoppable-stack-cli-0.4.0-beta.1.tgz
export PATH="$HOME/.local/bin:$PATH"
cd ~
us --version

Extract the plugin download

Download the archive above, then run this from your Downloads folder in a macOS or Linux shell. Adjust the folder if your browser saves elsewhere. Keep this terminal open and retain the extracted folder for the local catalog.

bash

$ cd ~/Downloads
tar -xzf unstoppable-stack-plugins-0.1.2.tar.gz
PLUGIN_DIR="$(pwd)/unstoppable-stack-plugin"

Install in Claude Code

Add the extracted catalog and install Unstoppable Stack for your user. This installs guidance; it does not download app dependencies or models.

bash

$ claude plugin marketplace add "$PLUGIN_DIR"
claude plugin install unstoppable-stack@unstoppable-stack-dev --scope user

Start a fresh workspace session

This example creates ~/shop-workspace, then launches Claude there after installation. Choose another directory or name if you prefer, and use a new folder.

bash

$ cd ~
mkdir shop-workspace
cd shop-workspace
claude

Activate the entry skill

Enter this in the Claude chat, then describe your app. The namespaced command should be available in the new session.

text

/unstoppable-stack:build-with-unstoppable

Describe the first app

Use a small desktop baseline to check the setup. The assistant should inspect the installed CLI and tell you which generated app folder to run.

text

Scaffold a Pear Desktop app named shop-starter with local storage and peer networking. Use the installed Unstoppable Stack CLI’s actual catalog, keep storage and networking in the worker, install the app dependencies and tell me which folder to run.

Check the result

Run the generated app from shop-starter, save an entry, close it normally and open it again to confirm persistence. Make one small visible change with your assistant. Local AI can be added after the baseline works; it needs compatible hardware and a model download.

If the skill does not appear

Confirm both catalog registration and plugin installation completed, then start a fresh session in the intended workspace. Keep the entire extracted folder together. If your project already has CLI-generated guidance, preserve its instructions and inspect overlap before migrating. Use the raw CLI guide while a host installation issue is unresolved.

Use the raw CLI

Scaffold the same baseline directly from the terminal.
