# Quick start
|
|
|
|
English | [中文](quickstart.zh.md)
|
|
|
|
This guide gets an agent running in five minutes.
|
|
|
|
## Prerequisites
|
|
|
|
- [Node.js](https://nodejs.org/) ^22.19 or >= 24
|
|
- [pnpm](https://pnpm.io/) 11 through Corepack
|
|
- A [DeepSeek Platform](https://platform.deepseek.com/) API key
|
|
|
|
```sh
|
|
node -v
|
|
corepack enable
|
|
pnpm -v
|
|
```
|
|
|
|
## Step 1: install and configure the API key
|
|
|
|
```sh
|
|
git clone https://github.com/deepseek-harness/deepseek-harness.git
|
|
cd deepseek-harness
|
|
pnpm install
|
|
```
|
|
|
|
Create the gitignored repository-root `.env`:
|
|
|
|
```sh
|
|
DEEPSEEK_API_KEY=sk-your-key-here
|
|
```
|
|
|
|
## Step 2: run one Headless task
|
|
|
|
Run a non-interactive task and print its final answer:
|
|
|
|
```sh
|
|
pnpm run demo:headless "summarize the architecture of this workspace"
|
|
```
|
|
|
|
Headless runs one complete model/tool turn, persists the session, prints the result, and exits. Use `--output-format stream-json` when you need the canonical event stream.
|
|
|
|
## Step 3: use the TUI
|
|
|
|
Start the interactive coding agent:
|
|
|
|
```sh
|
|
pnpm run demo:tui
|
|
```
|
|
|
|
The full-screen agent can read and write files, run commands, delegate subtasks, and track a plan. Try: `Create hello.js in the current directory, print "Hello from Harness!", and run it`.
|
|
|
|
## What happened
|
|
|
|
headless-agent uses the `@deepseek-ai/dsh-cli-demo` app; tui-agent uses the interactive `@deepseek-ai/dsh-tui-demo` app. Both load the same providerless agent spine, while their `cordis.yml` files select the DeepSeek model and capability plugins appropriate to each surface.
|
|
|
|
## Next steps
|
|
|
|
- [Configuration](./config.md) — understand the `cordis.yml` format
|
|
- [Develop a plugin](../develop/basic/) — build your own tool or backend
