Best ForDiagnosing SDK connection, auth, and message processing issues

When to Use This Skill

  • SDK connection failures, auth errors, or AMQP link errors
  • Idle timeout, connection inactivity, or slow reconnection after disconnect
  • AMQP link detach or detach-forced errors
  • Message lock lost, message lock expired, lock renewal failures, or batch lock timeouts
  • Session lock lost, session lock expired, or session receiver errors
  • Event processor or message handler stops processing
  • Duplicate events or checkpoint offset resets
  • SDK configuration questions (retry, prefetch, batch size, receive batch behavior)

MCP Tools

ToolCommandUse
mcp_azure_mcp_eventhubsNamespace/hub opsList namespaces, hubs, consumer groups
mcp_azure_mcp_servicebusQueue/topic opsList namespaces, queues, topics, subscriptions
mcp_azure_mcp_monitorlogs_queryQuery diagnostic logs with KQL
mcp_azure_mcp_resourcehealthgetCheck service health status
mcp_azure_mcp_documentationDoc searchSearch Microsoft Learn for troubleshooting docs

Diagnosis Workflow

  1. Identify the SDK and version — Check the prompt for SDK and version clues; if not stated, proceed with diagnosis and ask later if needed
  2. Check resource health — Use mcp_azure_mcp_resourcehealth to verify the namespace is healthy
  3. Review the error message — Match against language-specific troubleshooting guide
  4. Look up documentation — Use mcp_azure_mcp_documentation to search Microsoft Learn for the error or topic
  5. Check configuration — Verify connection string, entity name, consumer group
  6. 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/.
