## 🚀 CLI Commands (Verified Working)
### Export
```bash
# Export specific repository
cgc bundle export numpy.cgc --repo /path/to/numpy
cgc export numpy.cgc --repo /path/to/numpy # Shortcut
# Export all indexed repositories
cgc bundle export all-repos.cgc
# Export without statistics (faster)
cgc bundle export quick.cgc --repo /path/to/repo --no-stats
```
### Import
```bash
# Import bundle (add to existing graph)
cgc bundle import numpy.cgc
# Import and clear existing data
cgc bundle import numpy.cgc --clear
```
### Load
```bash
# Load bundle (convenience command)
cgc load numpy.cgc
cgc load numpy.cgc --clear
# Future: Download from registry
cgc load numpy # Will download numpy.cgc from registry
```

## 📊 Bundle Format
### Structure
```
numpy.cgc (ZIP archive)
├── metadata.json # Repo info, commit, languages
├── schema.json # Graph schema (labels, relationships)
├── nodes.jsonl # All nodes (streaming JSONL)
├── edges.jsonl # All relationships (streaming JSONL)
├── stats.json # Graph statistics
└── README.md # Human-readable description
```
### Example metadata.json
```json
{
"cgc_version": "0.1.0",
"exported_at": "2026-01-13T23:00:00",
"repo": "numpy/numpy",
"commit": "a1b2c3d4",
"languages": ["python", "c"],
"format_version": "1.0"
}
```

## 🤖 GitHub Actions Workflow
### Trigger
- **Weekly**: Sunday 00:00 UTC
- **Manual**: Via workflow_dispatch
### Process
1. Checkout CodeGraphContext
2. Install dependencies
3. Clone target repository (numpy, pandas, etc.)
4. Index repository with `cgc index`
5. Export to `.cgc` bundle
6. Generate bundle info markdown
7. Upload as artifact
8. Create GitHub Release
### Output
- **Tag**: `bundles-YYYYMMDD`
- **Assets**: `<repo>-<version>-<commit>.cgc`
- **Example**: `numpy-1.26.4-a1b2c3d.cgc`
---
## 🎯 Use Cases
### 1. Instant AI Context
```bash
wget https://github.com/.../numpy-1.26.4.cgc
cgc load numpy-1.26.4.cgc
# AI can now query numpy structure instantly!
```
### 2. Team Onboarding
```bash
# Create bundle
cgc export company-api.cgc --repo /path/to/api
# Share with team
# They load instantly
cgc load company-api.cgc
```
### 3. CI/CD Analysis
```bash
# Load pre-indexed dependencies
cgc load fastapi.cgc
cgc load sqlalchemy.cgc
# Analyze your code
cgc index ./my-api
cgc analyze deps my_api
```
### 4. Education
```bash
# Students explore famous codebases
cgc load django.cgc
cgc find name authenticate
cgc analyze chain login authenticate
```

## 📈 Impact
### Before Bundles
- ⏱️ Index numpy: ~5-10 minutes
- 💾 Everyone indexes separately
- 🔄 Repeated work across users
- 📦 No distribution mechanism
### After Bundles
- ⚡ Load numpy: ~10 seconds
- 📦 Index once, distribute everywhere
- 🌐 Share via GitHub Releases
- 🎯 Instant AI context
**Speedup: 30-60x faster for end users!**
