"""
Example showing how to use AgentOS with JSON files hosted in GCS as database.
GCS JSON Database Setup:
- Uses JSON files stored in Google Cloud Storage as a lightweight database
- Only requires a GCS bucket name - authentication follows the standard GCP patterns:
* Local development: `gcloud auth application-default login`
* Production: Set GOOGLE_APPLICATION_CREDENTIALS env var to service account key path
* GCP instances: Uses instance metadata automatically
- Optional prefix parameter for organizing files (defaults to empty string)
- Automatically creates JSON files in the bucket as needed
Prerequisites:
1. Create a GCS bucket
2. Ensure proper GCS permissions
3. Install google-cloud-storage: `uv pip install google-cloud-storage`
