Forgive me if this is out of place...
I love this hook! I found it by a Google search, after looking through Taskwarror's list of tools and not finding it there.
Based on the text at the top of that page, I think if you edit the repo's "About" text (the "description") to use the official spelling "Taskwarrior" rather than "Task Warrior", then your tool would appear in that list.
