Auto-Commit Service

Automated commit message generation service using local LLM inference. Commits and pushes changes across lilith-platform repos every 15 minutes.

Features

• Generates commit messages using llama-service (local 3B model)
• Processes multiple repositories in a cycle
• Automatic push with conflict resolution
• Claude Code fallback for complex failures
• FastAPI endpoints for monitoring and manual triggers

Installation

# Install the package
cd /var/home/lilith/Code/@packages/@ml/auto-commit-service
pip install -e .

# Or with model-boss integration (recommended)
pip install -e ".[model-boss]"

# Or with dev dependencies
pip install -e ".[dev]"

Model Configuration

The service requires a language model to generate commit messages. You have three options:

1. Auto-load via model-boss (recommended):

   pip install -e ".[model-boss]"
   # Models will be auto-downloaded and cached
   # Default: ministral-3b-instruct
   

2. Manual model path:

   export LLAMA_SERVICE_MODEL_PATH=/path/to/model.gguf
   

3. Disable auto-start (use external llama-service):

   export AUTO_COMMIT_LLAMA_SERVICE_AUTOSTART=false
   

Important: If no model is configured, the service will fail to start and report as down. This prevents making commits with placeholder messages.

Configuration

Environment variables (prefix: AUTO_COMMIT_):

Variable	Default	Description
AUTO_COMMIT_LLAMA_SERVICE_URL	http://localhost:8000	llama-service URL
AUTO_COMMIT_LLAMA_SERVICE_AUTOSTART	true	Auto-start llama-service if down
AUTO_COMMIT_LLAMA_MODEL_ID	deepseek-r1-70b	Model ID for model-boss
AUTO_COMMIT_USE_MODEL_BOSS	true	Use model-boss for model loading
AUTO_COMMIT_CYCLE_INTERVAL_SECONDS	900	Seconds between cycles (15 min)
AUTO_COMMIT_ENABLED	true	Enable daemon on startup
AUTO_COMMIT_CLAUDE_FALLBACK_ENABLED	true	Enable Claude Code recovery
AUTO_COMMIT_HOST	0.0.0.0	Service host
AUTO_COMMIT_PORT	8200	Service port

Usage

Run directly

python -m auto_commit_service

Run with uvicorn

uvicorn auto_commit_service:create_auto_commit_service --host 0.0.0.0 --port 8200

As systemd service

# Copy service file
sudo cp infrastructure/systemd/auto-commit.service /etc/systemd/system/

# Create environment file
sudo mkdir -p /opt/auto-commit
sudo tee /opt/auto-commit/.env << EOF
AUTO_COMMIT_LLAMA_SERVICE_URL=http://localhost:8000
AUTO_COMMIT_CYCLE_INTERVAL_SECONDS=900
EOF

# Enable and start
sudo systemctl daemon-reload
sudo systemctl enable auto-commit
sudo systemctl start auto-commit

API Endpoints

Endpoint	Method	Description
/health	GET	Service health check
/status	GET	Daemon status and last cycle
/trigger	POST	Manually trigger a cycle
/enable	POST	Enable the daemon
/disable	POST	Disable the daemon
/repos	GET	List configured repositories

Examples

# Check health
curl http://localhost:8200/health

# Get status
curl http://localhost:8200/status

# Trigger manual cycle
curl -X POST http://localhost:8200/trigger

# Disable daemon
curl -X POST http://localhost:8200/disable

Commit Style

Generated commits follow the Lilith Platform convention:

• ✨ feat: New feature
• 🔧 chore: Maintenance, config changes
• ♻️ refactor: Code restructuring
• 🐛 fix: Bug fix
• 📝 docs: Documentation
• ✅ test: Tests
• 🔥 remove: Removing code/files

Error Handling

1. No model configured: Service fails to start, reported as down (prevents bad commits)
2. Push rejected: Attempts git pull --rebase and retries
3. Merge conflict: Invokes Claude Code to resolve
4. Hook failure: Invokes Claude Code to fix
5. LLM unavailable: Service auto-starts if configured, otherwise skips cycle
6. Infrastructure errors (network, auth): Skips Claude recovery, reports error
7. Auth failure: Skips repo (requires manual fix)

Development

# Install dev dependencies
pip install -e ".[dev]"

# Run tests
pytest

# Run tests with coverage
