You want mathlib, the lean library of established results: https://github.com/leanprover-community/mathlib4

They skip steps in writing because they can generally do them and it obscures the flow of the argument to have every thing spelled out.

There is also a book on mechanics by the authors of SICP: https://mitpress.mit.edu/9780262028967/structure-and-interpr...

They do that in lean too; that's the idea of simp.

Lean doesn't have expressiveness notation. It's like Perl line noise.
