Bias Analysis

Detected Bias Types
powershell_heavy
missing_linux_example
windows_tools
Summary
The documentation provides only Azure PowerShell examples for configuring custom error pages, with no mention of Azure CLI, Bash, or other cross-platform/Linux-friendly tools. This creates a bias towards Windows users and may hinder Linux or macOS administrators who prefer or require non-PowerShell workflows.
Recommendations
  • Add equivalent Azure CLI examples for all PowerShell commands shown, demonstrating how to configure custom error pages using az network application-gateway commands.
  • Explicitly mention that both PowerShell and Azure CLI can be used, and provide links to relevant CLI documentation.
  • Where possible, include Bash script snippets or guidance for Linux/macOS users, especially for common tasks like uploading HTML files to Azure Blob Storage.
  • Review screenshots and UI instructions to ensure they are not Windows-specific (e.g., avoid showing only Windows file dialogs or PowerShell terminals).
