Azure Troubleshooting Skill

General Guidance

Always use tool-based queries first to fetch logs, metrics, and diagnostic data.
Only fall back to Azure CLI for deeper or unsupported inspection.

Investigations should:

1. Use Log Analytics Kusto queries with proper scoping
2. Use Activity Logs to identify failures
3. Use metrics when diagnosing performance issues
4. Provide minimal, targeted remediation advice
