Quickstart

The simplest possible Cline SDK example. Creates one agent, sends a single prompt, and streams the response to stdout.

Getting started

Use Node.js 22 or newer.

Install dependencies:

bun install
bun run build:sdk

Set an API key:

export CLINE_API_KEY="cline_..."

Run:

bun dev

What it does

1. Creates an Agent with a provider and model
2. Subscribes to assistant-text-delta events to stream output
3. Calls agent.run() with a prompt
4. Prints token usage when done
