What is claude-code

Claude Code is an innovative agentic coding tool developed by Anthropics that operates directly in your terminal. It is designed to enhance your coding efficiency by automating routine tasks, offering explanations for complex code snippets, and managing git workflows using natural language commands. This tool integrates seamlessly with your existing codebase, enabling you to code faster and more effectively.

How to Use claude-code

To get started with Claude Code, ensure you have Node.js version 18 or higher, as well as Node Package Manager (npm) installed on your system. Follow these steps:

Configure NPM Prefix: If you're new to Node.js and npm, it's recommended to set up an NPM prefix for your user. This helps maintain system security by allowing installations without administrative privileges.
Install Claude Code: Open your terminal and install Claude Code globally using npm with the command:
```
npm install -g @anthropic-ai/claude-code
```
Run Claude Code: Navigate to your project directory and initiate Claude Code by typing claude in the terminal.
Complete Setup: Finish the one-time OAuth authentication with your Anthropic Console account to start using Claude Code.

Key Features of claude-code

Claude Code is packed with features that streamline your development process:

Codebase Management: Effortlessly edit files and fix bugs across your entire codebase using simple natural language commands.
Code Understanding: Get answers to questions about your code's architecture and logic, making it easier to grasp complex structures.
Testing and Debugging: Execute, check, and correct tests, linting, and other commands to ensure your code runs smoothly.
Git Workflow Automation: Seamlessly search through git history, resolve merge conflicts, and manage commits and pull requests without leaving your terminal.

Claude Code is currently in a research preview, allowing developers to explore and provide feedback on their experiences. This helps Anthropics refine and improve the tool based on real-world usage. As part of this beta phase, users are encouraged to report any issues or bugs directly within the tool, which assists in enhancing its functionality.

With privacy and data security as a priority, Claude Code employs several safeguards to protect user data, including limited data retention and restricted access to user session information. This ensures that while feedback is used to improve the service, it is not used for training generative models.

Get started

If you are new to Node.js and Node Package Manager (npm), then it is recommended that you configure an NPM prefix for your user. Instructions on how to do this can be found here. Important We recommend installing this package as a non-privileged user, not as an administrative user like root. Installing as a non-privileged user helps maintain your system's security and stability.
Install Claude Code:

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

Navigate to your project directory and run claude.
Complete the one-time OAuth process with your Anthropic Console account.

Research Preview

We're launching Claude Code as a beta product in research preview to learn directly from developers about their experiences collaborating with AI agents. Our aim is to learn more about how developers prefer to collaborate with AI tools, which development workflows benefit most from working with the agent, and how we can make the agent experience more intuitive. This is an early version of the product experience, and it's likely to evolve as we learn more about developer preferences. Claude Code is an early look into what's possible with agentic coding, and we know there are areas to improve. We plan to enhance tool execution reliability, support for long-running commands, terminal rendering, and Claude's self-knowledge of its capabilities -- as well as many other product experiences -- over the coming weeks.

Reporting Bugs

We welcome feedback during this beta period. Use the /bug command to report issues directly within Claude Code, or file a GitHub issue.

Data collection, usage, and retention

When you use Claude Code, we collect feedback, which includes usage data (such as code acceptance or rejections), associated conversation data, and user feedback submitted via the /bug command.

How we use your data

We may use feedback to improve our products and services, but we will not train generative models using your feedback from Claude Code. Given their potentially sensitive nature, we store user feedback transcripts for only 30 days. If you choose to send us feedback about Claude Code, such as transcripts of your usage, Anthropic may use that feedback to debug related issues and improve Claude Code's functionality (e.g., to reduce the risk of similar bugs occurring in the future).

Privacy safeguards

We have implemented several safeguards to protect your data, including limited retention periods for sensitive information, restricted access to user session data, and clear policies against using feedback for model training. For full details, please review our Commercial Terms of Service and Privacy Policy.
