Quick Start

# Deploy Understudy in any project
cd /path/to/your/project
understudy
# → Choose platforms: Copilot, Claude Code, Cursor

# Then open your AI tool
claude            # Claude Code

Zero-question deploy (`--here`)

cd /path/to/your/project
understudy --here          # shows inferred values, asks one confirmation
understudy --here --yes    # fully unattended, no prompts
