🚀 Quick Install

Option 1: Global CLI (Recommended)

# Install globally
npm install -g jstar-reviewer

# In any project directory:
jstar setup      # Create config files
jstar init       # Index the codebase
jstar review     # Review staged changes

Option 2: One-Curl (Adds to current project)

curl -fsSL https://raw.githubusercontent.com/JStaRFilms/jstar-code-review/v2.0.0/setup.js | node

After Install:

1. Check Config: The tool now auto-creates .env.example and .jstar/ when you run it.
2. Add Keys: Copy .env.example → .env.local and add your GEMINI_API_KEY and GROQ_API_KEY.
3. Index: Run jstar init (or pnpm run index:init) to build the brain.
4. Review: Stage changes (git add) and run jstar review (or pnpm run review).
