Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows -- all through natural language commands.
Runs autonomously with minimal supervision
Works directly in command line environments
Understands entire codebases and dependencies
First tool of its kind from major AI provider
Accelerates development cycles significantly
Single developer can feel like "an everything guy"
Claude model family is best-in-class for agentic engineering
Monthly subscription includes Claude Code access
Standard Anthropic API rates
Via Amazon Bedrock or Google Cloud
Optimizes performance and cost using lightweight Haiku where appropriate
โ macOS, Linux, and Windows via WSL โ Enterprise deployment via Amazon Bedrock and Google Cloud Vertex AI โ Works with existing IDEs and development tools
"think" < "think hard" < "think harder" < "ultrathink"
Model Context Protocol (MCP) is an open standard that enables Claude Code to connect with external tools, databases, and services, making it highly extensible for organization-specific needs.
Advanced repository management, issue tracking, code reviews
Direct database queries and schema understanding
Team communication and notification integration
Build connectors for proprietary tools
Small team pilot with non-critical projects
Expand to larger teams with cost monitoring
Organization-wide rollout with governance
Get Claude Code running in your environment
Master essential commands and basic workflows
Learn sophisticated development patterns
Provide effective context for better results
Extend Claude Code with external tools and integrations
Optimize token usage and control costs
# Install via npm npm install -g @anthropic-ai/claude-code # Navigate to your project directory cd your-project # Start Claude Code claude
Complete the one-time OAuth authentication with your Anthropic Console account or Claude Pro/Max subscription.
Includes Claude Code access
Pay-as-you-go API pricing
# Basic usage claude "fix the type errors in the auth module" claude "how does our authentication system work?" # Git operations claude commit # Create commit with AI-generated message claude "create a pr" claude "rebase on main and resolve any merge conflicts" # Context management /cost # Check current token usage and costs /compact # Summarize conversation history to reduce tokens /clear # Clear conversation context /init # Generate comprehensive CLAUDE.md guide for project
Use specific phrases to trigger extended thinking:
"think" (4,000 tokens) < "think hard" < "think harder" < "ultrathink" (31,999 tokens)
# Autonomous mode (USE CAREFULLY) claude --dangerously-skip-permissions # Best practice: Use in Docker container without internet
# 1. Initial exploration claude "what does the payment processing system do?" claude "find where user permissions are checked" # 2. Generate project documentation /init # Creates CLAUDE.md with project context
# 1. Research phase claude "think hard about problem Y, investigate multiple approaches" # 2. Planning phase claude "create a plan for solving this with 3 different strategies" # 3. Implementation claude "implement the best approach"
# Step 1: Research and plan claude "think about implementing feature X, research the codebase first" # Step 2: Write failing tests claude "write tests for feature X based on expected input/output pairs" # Step 3: Commit tests claude "commit the tests when satisfied" # Step 4: Implement code claude "now implement the feature to make tests pass"
# Complex changes across codebase claude "refactor the authentication system to use new error handling pattern" claude "update all files that import the old auth module"
# Project root: Overall project context project-root/CLAUDE.md # Module-specific: Component guidelines src/auth/CLAUDE.md # Global: Organization standards ~/.config/claude/CLAUDE.md
# Project Context ## Architecture - Next.js frontend with TypeScript - Express.js backend with PostgreSQL - Redis for caching ## Coding Standards - Use functional components with hooks - Follow ESLint rules strictly - Write unit tests for all business logic ## Common Commands - `npm run test` - Run test suite - `npm run lint` - Check code style - `docker-compose up` - Start development environment ## Deployment - Staging: Automatically deploys from main branch - Production: Manual deployment via GitHub Actions
Model Context Protocol allows Claude Code to connect with external tools, databases, and services, extending its capabilities beyond basic coding tasks.
# Install GitHub CLI and MCP server gh auth login npm install -g @anthropic-ai/mcp-server-github # Configure Claude Code # Add to ~/.config/claude/config.json { "mcpServers": { "github": { "command": "mcp-server-github", "args": ["--token", "your-token"] } } }
# Example: PostgreSQL MCP server npm install -g @anthropic-ai/mcp-server-postgres # Usage with Claude Code claude "query the users table to find accounts created this month"
# GitHub integration workflows claude "create an issue for the bug we just found" claude "review the open PRs and summarize their status" claude "check the CI status for the latest commit" # Database workflows claude "analyze the performance of our recent queries" claude "suggest optimizations for the user_analytics table" # Slack integration claude "notify the team channel about deployment completion"
Organizations can build custom MCP servers for:
# Monitor costs frequently /cost # Compact conversations to reduce token usage /compact # Clear context when starting new tasks /clear # Use environment variables for cost control export DISABLE_PROMPT_CACHING=true
Simple questions, small fixes
Planning, analysis tasks
Complex refactoring, architecture decisions
Most challenging problems requiring deep analysis
# Headless mode for automation claude -p "fix all lint errors in the codebase" --headless # GitHub Actions integration - name: Fix code issues run: claude -p "address all failing tests" --headless
# Use containers for risky operations docker run -it --rm -v $(pwd):/workspace claude-code-container claude --dangerously-skip-permissions # Regular checkpoints claude "commit current progress before major changes"
Claude Code works with Model Context Protocol servers for extended capabilities:
# Systematic debugging approach claude "analyze the error logs and identify root cause" claude "think about the fix strategy with minimal risk" claude "implement the fix and test thoroughly"
Begin with low-risk tasks to learn the tool
Token usage can accumulate quickly
Provide context for better results
Use thinking modes for complex problems
Use containers for autonomous operations
Use /compact to maintain efficient conversations
