3. Usage

Claude Code

npm install -g @anthropic-ai/claude-code
cd my-project && claude
 
> Explain this project's structure
> Add rate limiting to the login API
> Run tests and fix any failures
> Commit changes and create a PR
 
# One-liner
claude -p "Update the README.md"
 
# Pipeline
cat error.log | claude -p "Analyze this error and fix it"

GitHub Copilot

# In VS Code
1. Install GitHub Copilot extension
2. Auto-suggestions appear as ghost text while typing
3. Tab to accept, Esc to dismiss

# Copilot Chat
@workspace Where is authentication code in this project?
/fix Fix the bug in this function
/test Write unit tests for this function

Cursor

# AI-native IDE (VS Code fork)
# Inline edit: Cmd+K → "Convert this function to async"
# Sidebar chat: Cmd+L → @codebase Explain the auth flow
# Composer: Cmd+I → "Add rate limiting to login API"
#   → Modifies multiple files simultaneously with diff view

6. Workflow Integration

Recommended Combinations

Combo 1: Claude Code + Copilot (most popular)
  - Copilot: Daily coding (fast autocomplete)
  - Claude Code: Complex tasks (refactoring, debugging, PRs)

Combo 2: Claude Code + Cursor
  - Cursor: IDE code editing (visual diffs)
  - Claude Code: Terminal-based autonomous tasks

Combo 3: Single tool
  - Claude Code only: CLI-preferred, terminal-centric workflow
  - Cursor only: IDE-centric, visual editing preferred
