lol, I went to the repo expecting to see some more detailed skill, that has instructions on checking various things/PHP install locations/things that could be using PHP that need to be checked, webservers, docker containers, etc/instructions for checking various php deployment methods on cloud providers/etc... i.e. making the skill useful so that it can check lots of places.
Nope, it just says to run php -V and has a table of vulnerable vs non-vulnerable versions.
Sigh
