cool, sorry if i missed this but what initially inspired you to make alint?
In order to make it more generally useful I went through a bunch of open source repos to see what kind of hygiene/validations they do - and it turns out quite a few repos have their own scripts and validation for similar purposes - I've been gradually adding more rules/validation types to cover more use cases.
In the process I also discovered repolinter [0] - a similar to tool which is now archived.
