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
copilot           # GitHub Copilot CLI
cursor .          # Cursor

Zero-question deploy (`--here`)

Already inside an existing repo and don't want to answer the wizard's questions? Use `--here` — Understudy infers project name, description, stack, repository URL and PM from the files in your working directory:

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

What gets inferred:

• Project name — from the folder name or root
