Claude Code – AI Terminal Coding Assistant by Anthropic

What is Claude Code?

Claude Code is an AI-powered coding assistant developed by Anthropic that runs directly in your terminal. It understands your project, takes natural language commands, and helps you write, refactor, debug, test, and create pull requests—without leaving the CLI

Why Choose Claude Code?

• Agentic in-terminal workflows: It navigates your codebase, edits files, and runs commands based on your natural prompts
• Seamless IDE integration: No server required. Install via npm and authenticate through your Claude Pro/Max subscription or Anthropic Console
• Secure & private: It uses direct API connections, stores feedback briefly (30 days), and does not train on your code .
• Enterprise-ready: Supports Amazon Bedrock and Google Vertex AI integrations for team-scale setups
• Multi-language SDKs: Provides CLI tools as well as TypeScript and Python SDKs

Core Features of Claude Code

• Code Editing & Bug Fixes: Automatically refactor code and resolve errors across files .
• Ask Code Questions: Ask project-specific questions like "How does authentication work?" or "Explain the cache layer"
• Testing & Debugging: Run tests, diagnose failures, and apply fixes in one step .
• Automate Git Tasks: Create commits, pull requests, resolve merge conflicts, search git history with CLI commands
• Slash Commands & Tools: Use built-in CLI commands like /bug, /init, /continue, /doctor, and /compact to manage context, report issues, or initialize project documentation

How to Start Using Claude Code

1. Subscribe to Claude Pro or Max, or sign up on Anthropic Console.

2. Run: npm install -g @anthropic-ai/claude-code in your terminal.

3. Inside your project directory, run claude and authenticate via OAuth.

4. Try commands like:

   • claude summarize this project

Claude Code Tips & Tricks

• Use /init to generate a CLAUDE.md file that captures project context, coding style, and workflows
• Try slash commands like /continue, /compact, /bug, or /doctor to optimize sessions and debug issues
• Secure environment: Approve only safe permissions—file edits and bash commands require explicit confirmation
