Commands

# Fetch package(s)
npx opensrc <package>
npx opensrc ai zod @anthropic-ai/sdk

# Check what's fetched
cat opensrc/sources.json

# Clean up when done
rm -rf opensrc/<package>

Exploration Pattern

# 1. Fetch
npx opensrc ai

# 2. Check structure (many are monorepos)
ls opensrc/ai/packages/

# 3. Find what you need
grep -r "functionName" opensrc/ai/src/

# 4. Read the implementation
# (use Read tool)

# 5. Clean up
rm -rf opensrc/ai

Tips

Check sources.json first - don't re-fetch what's already there
Target specific files - don't read entire packages
Monorepos: Check packages/ directory for subpackages
Clean up - source code takes disk space, remove when done
