Example: Enhanced Public Function Documentation

<#
.SYNOPSIS
Enables interactive management of Azure Kubernetes Service (AKS) clusters across all subscriptions.

.DESCRIPTION
Set-AksClusters provides an interactive interface for managing AKS clusters across all 
subscriptions in your Azure tenant. It allows you to select clusters and perform various 
management actions such as getting kubectl credentials, testing connections, and updating 
cluster resources.

.EXAMPLE
Set-AksClusters
Launches the interactive AKS cluster management interface.

.EXAMPLE
Set-AksClusters -SetupAllWithDefaults
Processes all AKS clusters with default settings without user interaction.

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.powershellgallery.com
  • Triggering command: pwsh -c Install-Module -Name Pester -Force -SkipPublisherCheck (dns block)
  • Triggering command: pwsh -c Get-PSRepository (dns block)
  • Triggering command: pwsh -c Register-PSRepository -Default; Install-Module -Name Pester -Force -SkipPublisherCheck (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

@copilot Your changes to ci.yml workflow are causing the Action to fail when it runs in the checks. The error is as follows:

Fixed in 31a0a09. The error was caused by a mismatch between the XML format generated by Pester (NUnit) and the format expected by the test reporter (JUnit). Changed the reporter configuration from java-junit to dotnet-nunit to properly parse the NUnit XML format that Pester generates.

Fixed in 1e1c774. The issue was using an invalid reporter value 'dotnet-nunit'. Changed the Pester output format from 'NUnitXml' to 'JUnitXml' and the test reporter from 'dotnet-nunit' to 'java-junit' to properly match the XML format with the expected reporter type.

Fixed in c9ab619. The error was caused by missing GitHub Actions permissions. Added checks: write permission to the workflow which is required for the dorny/test-reporter action to create check runs in the repository.

@copilot Given the information about using test-reporter from pull requests from forks of repositories at https://github.com/dorny/test-reporter?tab=readme-ov-file#example, should we try to add logic to the workflow to only run the task to create the check run on PRs from within the same repo?

Fixed in 9b13b72. Added conditional logic to only run the test reporter for same-repository PRs or push events. The step now uses if: always() && (github.event_name == 'push' || github.event.pull_request.head.repo.full_name == github.repository) which prevents the "Resource not accessible by integration" error when PRs come from forks with limited permissions.

...

Fixed in 88e20a4. The error was caused by an incorrect property name allowlist which should be Whitelist in the PSAvoidUsingCmdletAliases rule configuration. Also simplified the PSScriptAnalyzer settings by removing the explicit IncludeRules list that was conflicting with IncludeDefaultRules = $true.
