The Agent Skills Directory

[Official API Integration]: The skill uses the Azure CLI (az) and the az rest command to communicate with the Microsoft Fabric API at api.fabric.microsoft.com. This ensures that all operations are performed against official, trusted endpoints using the user's existing security context.
[Diagnostic Code Execution]: The skill generates and submits PySpark diagnostic snippets to remote Spark clusters via Livy. These scripts are used to gather performance metrics (like executor memory and partition stats) and are a standard part of Spark troubleshooting.
[Session and Job Management]: It includes patterns for listing, monitoring, and cleaning up Spark sessions. These administrative tasks are performed through authenticated REST calls, providing a secure way to manage cluster resources.
[Log Retrieval Practices]: The skill demonstrates how to retrieve and paginate through Spark driver and executor logs. This is essential for debugging and is implemented using official Fabric monitoring APIs.
[Data Input Surface]: While the skill processes external data (API responses and logs), which is a common surface for indirect instructions, it focuses on structured analysis and standard diagnostic workflows within a controlled environment.
