Second, at the risk of disrupting the author's groove (and further belaboring the established criticism of the project name), I've become accustomed to git's convention for commands. A synonymous git-task command would be nice to have for something like this.
I'm sorry but I'm a little confused as to what the second part of your comment is suggesting. Are you saying that the name should be changed to something like git-task, or that the commands for the utility should follow git's command conventions?
git task list
git task new "Fix homepage styling"
That can be achieved if you put something like this on .gitconfig:
[alias]
task = !tigger
