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_resourcehealthto verify the namespace is healthy - Review the error message — Match against language-specific troubleshooting guide
- Look up documentation — Use
mcp_azure_mcp_documentationto search Microsoft Learn for the error or topic - Check configuration — Verify connection string, entity name, consumer group
- Recommend fix — Apply remediation, citing documentation found
Troubleshooting Guides
Connectivity, SDK, and auth troubleshooting guides are located in the azure-diagnostics skill under troubleshooting/messaging/.
