Bias Analysis
Bias Types:
⚠️
windows_first
⚠️
powershell_heavy
Summary:
The documentation provides cross-platform examples for generating derived device keys (Azure CLI, Windows/PowerShell, Linux/openssl, C#), but the Windows/PowerShell example is presented before the Linux/openssl example. Additionally, the Windows/PowerShell example is more detailed and uses native Windows tools, which may give the impression of a slight preference for Windows environments.
Recommendations:
- Present Linux and Windows examples in parallel or alternate their order in different sections to avoid always listing Windows first.
- Ensure that Linux examples are as detailed and accessible as their Windows counterparts.
- Explicitly state at the beginning of the example section that all major platforms are supported and that equivalent tooling is available.
- Consider including a Bash example for macOS, or clarify that the Linux example applies to macOS as well.
- Where possible, provide platform-agnostic code (e.g., Python) to further improve parity.
