You approach challenges with a pragmatic mindset, prioritizing efficiency and maintainability.

Your task: I want the library concept to be completely different from the collections concept. Also, libraries should not appear on the prompt builder. They are for users to create and share.

Libraries should appear in the sidebar in the same section as prompts. Libraries should allow:

- The owner should be able to create a library
  -> Title
  -> Description
  -> Tags
  -> Public/Private

- The owner should be able to remove a library
- The owner should be able to edit a library
- The owner should be able to add prompts to a library
- The owner should be able to remove prompts from a library

- All users should be able to share a library if they have access to it
- All users should be able to embed a library if the library is public
- All users should be able to add comments to a library
- All non-owner users should be able to favorite, upvote, and downvote a library

A library should have an authenticated and non-authenticated detail page. When sharing a library, the default link is the unauthenticated detail page, but on page load, this should redirect to the authenticated page if a user is logged in. This behavior is present for other building blocks as well; align this implementation with that implementation.

The layout of the library detail page should mimic the layout of the other building block detail pages: a grid of cards that show the title, description, favorites, upvotes, amount of comments, date, tags, etc. But also the amount of prompts that the library contains. The grid should use the same tabbing as the other building block pages (Mine, public, etc.) and the same pagination as on the other building block pages.

On prompt detail pages, a button should appear (Add to library), which opens a modal where users can select the library (one or more) to add it to. Users can only add to their own libraries. Take into account performance, make sure that at most 5 libraries are returned by the query used in the modal, and that searching and ordering allows the user to find the libraries he/she is looking for. What might even be better is if you re-use the 

I want the following limits applied to users with a free subscription:

- No private libraries
- Unlimited public libraries

Study the codebase, think about the best approach, and propose an implementation plan.

The tone of the output should be Professional, Direct, Analytical, Skeptical.

Always adhere to the following constraints: Never make assumptions, ask questions if something is not clear, call out inconsistencies. If you need more information from me, ask me 1-2 key questions right away. Don't be a yes-man.
