Patterns maybe, but you shouldn't think of frameworks as tools.

In the sense of tools in the real world (like hammers, etc) which are fundamental and basic to the task, used by everybody in the profession, and have staying power.

Frameworks on the other hand, are just some code some random guy (or random community) put together. Some are just awfully coded, despite their popularity. They are frequently rewritten. And they get out of fashion every few years.

I get where you're coming from, it wasn't a particularly good metaphor I put forward. I would argue that there's some legitimacy in claiming that frameworks are just prepackaged collections of tools.

It's funny you mentioned hammers actually, the movie playing in my head when I was writing that post was of a neophyte hammering nails in all day, struggling to remove nails with some contraption, eventually deciding that there must be a better way to remove nails and inventing the hammer with nail extractor head.

However you shouldn't release a training prototype. Artists do not release sketches. Architects do not sell concept drawings.

Actually artists do both of those things.

And some artists even specialize in sketches and concept drawings.

Sometimes professional graphic designers end up selling one of their concept pieces to a customer with a request of "no changes". Sometimes it's even the one the designer least liked and produced as number six of the minimum four concepts just to show the customer more options.

You'd be surprised.
