Appinsights Instrumentation

Microsoft's official guidance for adding Azure Application Insights telemetry to web applications. Covers SDK setup patterns for ASP.NET Core, Node.js, and Python apps, with specific instructions for auto-instrumentation versus manual setup depending on your hosting environment. Includes Bicep templates for resource creation and concrete code examples for each framework. The skill focuses purely on instrumentation guidance and delegates actual code changes to the azure-prepare skill. Honestly useful if you're working with Azure-hosted apps and need to understand the telemetry patterns before implementing them, though it assumes you're already committed to the Azure ecosystem.
