Depends on the project. Word on the street is the closer your project is to an archetypical React tutorial TODO App then you'll likely be pleased with the results. Whereas if your project is a WDK driver in Rust where every file is a minefield then you'll spend the next few evenings having to audit everything with a fine toothed comb.

That depends if you believe in documentation-first or program-first definitions of a specification.
