Diagnosis Workflow

Identify the SDK and version — Check the prompt for SDK and version clues; if not stated, proceed with diagnosis and ask later if needed
Check resource health — Use mcp_azure_mcp_resourcehealth to verify the namespace is healthy
Review the error message — Match against language-specific troubleshooting guide
Look up documentation — Use mcp_azure_mcp_documentation to search Microsoft Learn for the error or topic
Check configuration — Verify connection string, entity name, consumer group
Recommend fix — Apply remediation, citing documentation found
