What is Claude Code?

  • Command-line AI tool that lives in your terminal
  • Context-aware: Understands your entire project structure
  • Agentic: Can plan, execute, debug, and verify work
  • Integrated: Works directly with your git, filesystem, and tools
  • Secure: Designed for enterprise workflows

Pricing Plans

  • Pro Plan ($20/month)
    • Good for light usage (~10-40 prompts/5h)
  • Max Plan 5x ($100/month)
    • Serious development (~50-200 prompts/5h)
  • Max Plan 20x ($200/month)
    • Heavy agentic workflows (~200-800 prompts/5h)
TIP: Use Sonnet for speed and cost-efficiency. Use Opus for complex planning.

Core Productivity Features

  • Exploration: "Explain how the authentication flow works"
  • Refactoring: "Extract this logic into a separate service"
  • Testing: "Generate edge-case tests for this class"
  • Debugging: "Analyze this stack trace and fix the issue"
  • Git Integration: "Commit these changes with a conventional message"
