How could I pass shell script output to notification?

There needs to be a Set Value of Variable action in between the script and notification actions.

Set Value of Variable accepts input from previous action and assigns it to a variable with the name of your choice.

This variable is then available for other actions. Just start typing the name of the variable in a field and it should pop-up in the auto-suggestion.

In 10.9 or later, you can use the display notification AppleScript command:

osascript -e 'on run {t}' -e 'display notification "" with title "t"' -e end title

In 10.8 you can use terminal-notifier:

terminal-notifier -title title -message ''

terminal-notifier can be installed with sudo gem install terminal-notifier.
