I found myself writing a bunch of scripts and AGENTS.md for ensuring certain structure/organization for projects when using AI. The maintenance, performance, and reliability of these eventually became a problem, so I built this tool.
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.
