In this case you could be kinda sneaky and use the 'onlyif' parameter:
exec { "reload-squid":
command => "/etc/init.d/squid reload",
subscribe => Exec["check-squid"],
refreshonly => true,
onlyif => "/usr/sbin/squid -k parse",
}
Though in all honesty your init script should be doing that check (the one I
just looked at for my setup does) so you could just you the service type.
