$PAT = "your_personal_access_token"

# Base64 encode the PAT for authentication
$PATEncoded = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$PAT"))

# Function to invoke REST API calls
function Invoke-AzureDevOpsRestApi {
    param (
        [string]$Url
    )
    
    $Headers = @{
        "Authorization" = "Basic $PATEncoded"
        "Content-Type"  = "application/json"
    }
    
    try {
        $Response = Invoke-RestMethod -Uri $Url -Headers $Headers -Method Get
        return $Response
    } catch {
        Write-Error "Error invoking API: $($_.Exception.Message)"
        return $null
    }
}

# Get all agents
$AgentsUrl = "$OrgUrl/_apis/distributedtask/pools/1/agents?api-version=7.1"
$Agents = Invoke-AzureDevOpsRestApi -Url $AgentsUrl

if ($Agents) {
    Write-Host "Agent Status Report:"
    foreach ($Agent in $Agents.value) {
        Write-Host "Agent Name: $($Agent.name)"
        Write-Host "  Status: $($Agent.status)"
        Write-Host "  Current Job: $($Agent.assignedRequest.planId)" # This will be a GUID; you'd need to use the Timeline API to get details
        Write-Host "------------------------"
    }
} else {
    Write-Host "Failed to retrieve agents."
}

This script gives you a basic framework. You'll need to expand it to fetch job details using the Timeline API and handle the logic for different job statuses. Customize it for better results.
