The first thing structure101 does is simply to let you understand the structure of your code-base from different perspectives.
You can define how the code should be structured - the architecture - in such a way that your entire team can easily understand it, move the structure towards it, and keep it so.
You can assign limits to the structural complexity and structure101 will measure the code at every level and highlight the regions that are excessively complex.
Most critically, structure101 tells you how your structure has changed from a reference structure - for example, what are the new dependencies, new architecture violations, complexity trends? This means you don't need to review everything all the time - just keep an eye on how it's evolving.
