Here is the documentation from Microsoft on how to request confirmations in a cmdlet. The examples are in C#, but you can do everything shown in PowerShell as well.

First add the CmdletBinding attribute to your function and set SupportsShouldProcess to true. Then you can reference the ShouldProcess and ShouldContinue methods of the $PSCmdlet variable.

Here is an example:

function Start-Work {
    <#
    .SYNOPSIS Does some work
    .PARAMETER Force
        Perform the operation without prompting for confirmation
    #>
    [CmdletBinding(SupportsShouldProcess=$true)]
    param(
        # This switch allows the user to override the prompt for confirmation
        [switch]$Force
    )
    begin { }
    process {
        if ($PSCmdlet.ShouldProcess('Target')) {
            if (-not ($Force -or $PSCmdlet.ShouldContinue('Do you want to continue?', 'Caption'))) {
                return # user replied no
            }

            # Do work
        }

    }
    end { }
}
