AWS Resource Discovery is a command-line tool that enumerates and catalogs all AWS resources within an account across multiple regions. The tool leverages the botocore library to systematically discover AWS services and identify the regions where they are deployed. It provides comprehensive visibility into an organization's AWS infrastructure by scanning for resources across all available services. The tool outputs discovery results in JSON format to stdout, making it suitable for integration with other security tools and automation workflows. Raw API responses can be saved to files using Python pickle format for further analysis or archival purposes. The tool includes error handling that raises exceptions when issues occur during the discovery process, ensuring reliable operation and clear feedback on any problems encountered during resource enumeration.
