Bias Analysis

Detected Bias Types
windows_first
os_type_windows_default
powershell_heavy
Summary
The documentation demonstrates a Windows bias in several ways: Windows is used as the default or sole OS example in disk creation commands (e.g., --os-type Windows), and PowerShell examples and notes are given equal or greater prominence than CLI or REST. There are no explicit Linux-specific examples or references to Linux disk types, and the documentation does not mention Linux-specific considerations or patterns. The ordering and language suggest Windows as the default use case.
Recommendations
  • Provide explicit Linux examples in CLI and REST sections, e.g., use --os-type Linux and show a Linux disk creation workflow.
  • Add notes or examples for Linux-specific scenarios, such as disk formats, guest state, or metadata differences.
  • Balance PowerShell and CLI coverage by including Bash/Linux shell script examples where appropriate.
  • Clarify that the feature is supported for both Windows and Linux VMs, and highlight any differences in usage or behavior.
  • Avoid using Windows as the default in examples; alternate or show both OS types in sample commands.
