Get started with Sovereign.

01

Prerequisites

Claude Code for the command-based installation, or a Cursor build with plugin marketplace support. For local development, use Node.js 20+ and pnpm.

02

Install in Claude Code

Add the Sovereign marketplace, then install the Engineering plugin using the commands below.

/plugin marketplace add nandahadymulya/sovereign
/plugin install engineering@sovereign

03

Install in Cursor

Use Cursor’s plugin UI or supported repository installation flow to add the Sovereign marketplace. Cursor reads the root .cursor-plugin/marketplace.json; Claude Code commands do not install plugins into Cursor.

04

Local development

Clone the marketplace repository, install dependencies with pnpm install, then launch Claude Code with the plugin directory command.

claude --plugin-dir ./plugins/engineering

05

Validate the plugin

Run pnpm validate in the Sovereign marketplace repository to check cross-manifest consistency. Optionally, use claude plugin validate ./plugins/engineering when the Claude Code CLI is available.

06

Troubleshooting

If a plugin is not discovered, confirm the marketplace was added for the correct platform, check the repository is available, then validate the manifests before trying again.
