react-flow

Prerequisites:

• [Claude Code](https://claude.ai/code) CLI installed
• [agent-browser](https://github.com/vercel-labs/agent-browser) for run-test-plan command (optional)

```bash

claude plugin marketplace add https://github.com/existential-birds/beagle

claude plugin install beagle

```

Verify installation by running /beagle: in Claude Code—you should see the command list.

To update: claude plugin update beagle

Troubleshooting:

• "Marketplace file not found": Remove stale entries from ~/.claude/plugins/known_marketplaces.json and restart Claude Code.
• Plugin not updating: Run claude plugin marketplace update beagle to refresh the marketplace, then claude plugin update beagle.

Other Agents

Use the [skills CLI](https://skills.sh/docs/cli) to install beagle skills for other AI agents:

```bash

npx skills add existential-birds/beagle

```

This downloads the skills and configures them for your agent. Commands (/beagle:*) are Claude Code specific and not available through the skills CLI.
