Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Azure Diagnostics > **AUTHORITATIVE GUIDANCE — MANDATORY COMPLIANCE** > > This document is the **official source** for debugging and troubleshooting Azure production issues. Follow these instructions to diagnose and resolve common Azure service problems systematically. ## Triggers Activate this skill when user wants to: - Debug or troubleshoot production issues - Diagnose errors in Azure services - Analyze application logs or metrics - Fix image pull, cold start, or health probe issues - Investigate why Azure resources are failing - Find root cause of application errors - Troubleshoot App Service issues (high CPU, deployment failures, crashes, slow responses, TLS/custom domains) - Respond to prompts like "troubleshoot app service", "app service high CPU", or "app service deployment failure" - Troubleshoot Azure Function Apps (invocation failures, timeouts, binding errors) - Find the App Insights or Log Analytics workspace linked to a Function App - Troubleshoot AKS clusters, nodes, pods, ingress, or Kubernetes networking issues - Troubleshoot Azure VM connectivity issues (RDP/SSH failures, port 3389/22 timeouts, NSG or firewall blocking, credential resets) - Troubleshoot Azure Me

What does the azure-diagnostics skill do?
Debug Azure production issues on Azure using AppLens, Azure Monitor, resource health, and safe triage. WHEN: debug production issues, troubleshoot app service, app service high CPU, app service deployment failure, troubleshoot container apps, troubleshoot functions, troubleshoot AKS, VM RDP, Linux SSH, VM black screen, can't connect to VM, reset VM password, NSG or firewall blocking, kubectl cannot connect, kube-system/CoreDNS failures, pod pending, crashloop, node not ready, upgrade failures, analyze logs, KQL, insights, image pull failures, cold start issues, health probe failures, resource
How do I install it?
Run `npx skills add microsoft/azure-skills --skill azure-diagnostics --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From microsoft/azure-skills, a repository with 1,353 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
