# Claude Code

Claude Code is an AI-powered coding assistance published by Anthropic that provides a terminal interface, allowing developers to delegate complex programming tasks directly from the terminal to Claude Code for completion.
Now, Novita provides [Anthropic SDK compatible LLM API services](/docs/guides/llm-anthropic-compatibility), enabling you to easily use Novita LLM models in Claude Code to complete tasks. Please refer to the guide below to complete the integration process.

Quick Start

###

[​](#1-install-claude-code)

1. Install Claude Code

Before installing Claude Code, please ensure your local environment has [Node.js 18 or higher](https://nodejs.org/en/download/) installed.

To install Claude Code, run the following command:

Bash

```
npm install -g @anthropic-ai/claude-code
```

###

[​](#2-start-your-first-session)

2. Start your first session

import from ‘/snippets/setup-api-key-guide.mdx’;

Please find the list of models currently available for use in Claude Code [here](/docs/guides/llm-anthropic-compatibility#supported-models).

Open the terminal and set up environment variables as follows:

Bash

```
# Set the Anthropic SDK compatible API endpoint provided by Novita.
export ANTHROPIC_BASE_URL="https://api.novita.ai/anthropic"
export ANTHROPIC_AUTH_TOKEN=""
# Set the model provided by Novita.
export ANTHROPIC_MODEL="moonshotai/kimi-k2-instruct"
export ANTHROPIC_SMALL_FAST_MODEL="moonshotai/kimi-k2-instruct"
```

Next, navigate to your project directory and start Claude Code. You will see the Claude Code prompt inside a new interactive session:

Bash

```
cd
claude .
```

[​](#3-build-a-web-game-from-scratch)

3. Build a web game from scratch

Input your task description, then press `Enter` to start this task.

Bash

```
> Create a ping-pong web game. Use only HTML, CSS, and JavaScript, try to create some novel content, and the final output should be a single HTML file.
```

![](https://mintcdn.com/novitaai/H3Kjvdvlhgt0Aohj/guides/images/claude-code/first-prompt.png?fit=max&auto=format&n=H3Kjvdvlhgt0Aohj&q=85&s=d614b2db042b9a50aa0ef0e779c0e5c9)

Claude Code will analyze your requirements, create a multi-step plan, and automatically begin executing the tasks.

After completing each task, Claude Code will mark it as complete and proceed to plan and explain the details of the next task.

[​](#4-task-results-and-preview)

4. Task Results and Preview

After all tasks are completed, you will see the following messages in the terminal:

![](https://mintcdn.com/novitaai/H3Kjvdvlhgt0Aohj/guides/images/claude-code/task-result.png?fit=max&auto=format&n=H3Kjvdvlhgt0Aohj&q=85&s=a0b21887d4ed3838a5862c66eb9f905d)

At this point, you can open the `gravity-pong.html` file in your browser to view and play the game.

[​](#5-use-git-with-claude-code)

5. Use Git with Claude Code

Claude Code makes Git operations conversational:

Bash

```
> what files have I changed?
```

Bash

```
> commit my changes with a descriptive message
```

You can also prompt for more complex Git operations:

Bash

```
> create a new branch called feature/quickstart
```

Bash

```
> show me the last 5 commits
```

Bash

```
> help me resolve merge conflicts
```

###

[​](#6-improve-the-game)

6. Improve the game

As we can see, this game needs improvement: the orbs’ position overlaps with the paddle’s position, which affects the gaming experience. Next, we will reposition the orbs to the top-right corner and add game restart functionality.

Bash

```
> Position the orbs in the top-right corner and support game restart functionality.
```

This is the game preview after the improvement:
