I love the methodology used by @EricShulman in https://tiddlytools.com/ for developing and sharing TiddlyWiki tools and solutions.
As an example see his recent answer to a question here: Show a partial list with an expandable "more" section - #2 by EricShulman
- The solution is stored in a TiddlyWiki online, so you can give a try before using in your own TiddyWiki
- The solution uses namespace, so finding all parts of solution is rather easy
- The solution contains the WikiText script in a dedicated tiddler
- The solution has description and examples in the Info tiddler
- The solution has a dedicated customized button to download it and reuse in your own wiki. The button also acts as a drag and drop handle, so you can directly import the solution to your wiki without downloanding
Everything is very clear.
Info (help/doc) tiddler
Download button
EDITED: This button also can be used as drag and a drop handle to directly import the solution to your wiki without downloading
