go-instabl is a static analysis tool that will calculate the instability metric. The closer the value gets to 0, the more packages inside the code base rely on this package, and the more responsible the package is. This means, the package is considered stable, and changes to this package may have significant impact on other packages. When the value is closer to 1, the package is more resilient to changes, as it is less coupled to other packages.
