    This skill is designed for Azure diagnostics and troubleshooting, providing a comprehensive set of guides and scripts that utilize standard tools like the Azure CLI and kubectl. It includes some security considerations, such as the ingestion of logs which provides a surface for indirect prompt injection, and the use of privileged debug pods for advanced diagnostics. These are used within the skill's intended functionality and are accompanied by appropriate guidance for user approval.
