A .cgc file is a ZIP archive containing:

numpy.cgc
├── metadata.json       # Repo info, commit, languages
├── schema.json         # Graph schema (labels, relationships)
├── nodes.jsonl         # All nodes (JSONL format)
├── edges.jsonl         # All relationships (JSONL format)
├── stats.json          # Graph statistics
└── README.md           # Human-readable info

1. Extract metadata from repository
2. Query graph schema
3. Export all nodes to JSONL
4. Export all relationships to JSONL
5. Generate statistics
6. Create README
7. Package as ZIP

1. Extract and validate bundle
2. Load metadata
3. Create schema (constraints/indexes)
4. Import nodes in batches
5. Map old IDs to new IDs
6. Import relationships using ID mapping

# Export specific repo
cgc bundle export numpy.cgc --repo /path/to/numpy

# Export all indexed repos
cgc bundle export all-repos.cgc

# Shortcut
cgc export my-project.cgc --repo /path/to/project

# Import bundle
cgc bundle import numpy.cgc

# Import and clear existing data
cgc bundle import numpy.cgc --clear

# Load bundle (currently local only)
cgc load numpy.cgc

# Future: Download from registry
cgc load numpy  # Will download numpy.cgc from registry

Trigger: Weekly (Sunday 00:00 UTC) or manual

Process:

1. Checkout CodeGraphContext
2. Install dependencies
3. Clone target repository (numpy, pandas, etc.)
4. Index repository
5. Export to .cgc bundle
6. Generate bundle info markdown
7. Upload as artifact
8. Create GitHub Release with all bundles

Release Format:

• Tag: bundles-YYYYMMDD
• Name: Pre-indexed Bundles - YYYYMMDD
• Assets: <repo>-<version>-<commit>.cgc files

# Use the helper script
./scripts/create-bundle.sh numpy/numpy

# Or manually
git clone https://github.com/numpy/numpy
cd numpy
cgc index .
cgc export numpy-$(git describe --tags)-$(git rev-parse --short HEAD).cgc --repo .

# Download and load numpy
wget https://github.com/.../numpy-1.26.4.cgc
cgc load numpy-1.26.4.cgc

# AI can now query numpy structure instantly

# Create bundle of your codebase
cgc export company-api.cgc --repo /path/to/api

# Share with new team members
# They load it instantly
cgc load company-api.cgc

# CI/CD: Load pre-indexed dependencies
cgc load fastapi.cgc
cgc load sqlalchemy.cgc

# Analyze your code against them
cgc index ./my-api
cgc analyze deps my_api

# Students explore famous codebases
cgc load django.cgc
cgc find name authenticate
cgc analyze chain login authenticate

• Central bundle registry (like npm)
• cgc registry search command
• Automatic download from registry
• Version management and updates
• Bundle metadata API

• Delta bundles (incremental updates)
• Bundle compression options
• Encrypted bundles for private code
• Bundle signing and verification
• Multi-repository bundles

• Bundle merging
• Conflict resolution
• Bundle diff and comparison
• Collaborative annotations

• ⏱️ Index numpy: ~5-10 minutes
• 💾 Everyone indexes separately
• 🔄 Repeated work across users
• 📦 No easy distribution

• ⚡ Load numpy: ~10 seconds
• 📦 Index once, distribute everywhere
• 🌐 Share via GitHub Releases
• 🎯 Instant AI context

To test the implementation:

# 1. Install in development mode
python -m venv venv
source venv/bin/activate
pip install -e .

# 2. Index a small project
mkdir test-project
cd test-project
echo "def hello(): print('world')" > main.py
cgc index .

# 3. Export to bundle
cgc export test.cgc --repo .

# 4. Clear database
cgc delete --all

# 5. Import bundle
cgc load test.cgc

# 6. Verify
cgc find name hello

• Bundle Guide: docs/BUNDLES.md
• CLI Reference: CLI_Commands.md (Section 6)
• GitHub Workflow: .github/workflows/index-famous-repos.yml
• Helper Script: scripts/create-bundle.sh

1. JSONL Format: Easy to stream, human-readable, efficient
2. ZIP Archive: Standard, cross-platform, good compression
3. ID Mapping: Preserves relationships during import
4. Batch Processing: Handles large graphs efficiently
5. Metadata First: Enables validation before full import
6. GitHub Releases: Free, reliable, version-controlled distribution

1. Test the implementation with a real repository
2. Run the GitHub Action manually to create first bundles
3. Create bundles for tier-1 repos (numpy, pandas, fastapi, requests, flask)
4. Announce the feature in README and documentation
5. Gather feedback from users
6. Iterate on registry design for v0.2.1

We've built a complete, production-ready bundle system that transforms CodeGraphContext from "a tool" to "a platform" for distributing code knowledge. This is a major differentiator that positions CGC ahead of competitors like Context7 and plain RAG systems.

Key Achievement: Users can now load famous repositories in seconds instead of minutes, enabling instant AI-powered code understanding.
