Claude Code Plugin

The Castari plugin for Claude Code lets you deploy agents without leaving your editor. Type /castari-deploy and the skill handles CLI installation, authentication, project scaffolding, and deployment — all in one flow.

​
Install the Plugin

npx skills add castari/cli
This installs the Castari plugin into your Claude Code environment. Once installed, the /castari-deploy skill is available in any project.

​
Using /castari-deploy

Type /castari-deploy in Claude Code (or ask Claude to “deploy to Castari”) and the skill walks through the full deployment flow:

​
Step 1: CLI Check

The skill checks if the Castari CLI is installed by running cast --version. If not found, it installs the CLI globally via npm.

​
Step 2: Authentication

Runs cast whoami to check if you’re logged in. If not, it triggers cast login which opens your browser for Clerk OAuth authentication.

​
Step 3: Project Configuration

Looks for castari.json in your project root. If one exists, the skill confirms its configuration with you. If not, it:
  • Detects your entrypoint file (e.g., src/index.ts, index.js)
  • Asks you for an agent name
  • Generates a castari.json manifest

​
Step 4: Deploy

Runs cast deploy to package your project and deploy it to an isolated cloud sandbox.

​
Step 5: Verification

Shows you a summary of the deployment — agent name, status, and sandbox ID.

​
Step 6: Testing

Offers to test the deployed agent by running cast invoke with a prompt you provide.

​
Trigger Phrases

The skill activates when you ask Claude to:
  • “deploy to Castari”
  • “deploy my agent”
  • “castari deploy”
  • “push agent to Castari”
  • “ship my agent”
  • “set up Castari”
Or any variation of deploying an agent to Castari.
