How does tsc get its definitions when using npm definitions

So I settled from using typings to just using npm. So you have the @types directory in node_modules, but besides that, there are no additional files.

With typings I always had to include the index.d.ts file in typings, but using npm this is not necessary. I want to ask why this is the case.

Does npm use some kind of hidden feature of tsc or did Microsoft and the people behind npm agree to something?

Yes, tsc automatically checks ./node_modules/@types. Take a look:

By default all visible “@types” packages are included in your compilation. Packages in node_modules/@types of any enclosing folder are considered visible; specifically, that means packages within ./node_modules/@types/, ../node_modules/@types/, ../../node_modules/@types/, and so on.
