AppleScript: Set folder name of Folder Action?

Question

Problem:
How to get the folder name that the running Folder Action script is attached too. Script is functional, stdin bash script with AppleScript via osascript. I just want the folder name, not the POSIX path to it. The System Events dictionary suggests this is possible. I don't want to hardcode the action's assigned folder in the bash script if I can get it dynamically from AppleScript. I know how to return it to bash. AppleScript newbie that has spent several hours googling and testing already.
Tried:
tell application "Finder"
     --AppleScript Editor can't get container -- no surprise. Folder action does work
     get POSIX path of (container of ((path to me) as text))
     set workingDir to quoted form of result
     display alert "Current Folder: " message workingDir as critical
end tell
tell application "System Events"
     activate
     --AppleScript Editor can't get name of folder action. Folder action does not work
     set currentDir to name of folder action
end tell
Appreciation for time and solution in advance.

In that case I suggest you make your life easier.  delete the osascript bit and just return a 0 or 1 from the shell script.  That integer will be passed on to the next action, so add an applescript action that checks to see if the input is 0 or 1 and displays a dialog if necessary:
on run {input, parameters}
          if input as integer > 0 then
  -- error
  display alert "whatever"
          end if
end run
The only reason I posted in the first place was to assess if it was possible to dynamically discover the folder name of the folder action using AppleScript through an osascript request. If the bash script has to be scrapped and entirely rewritten as a Applescript action -- just to obtain the folder name, then that answers my question.
The purpose of the osascript was to provide an OS X style, user friendly dialog that displays any martian files the bash script ignored. It was the least amount of coding for the result.
I believe that your input example from above would take the exit status from the preceding shell script. How is my invalidFiles variable passed then? In the shell script, I can pipe the invalidFiles printf line to pbcopy to put that content on the clipboard. After the script is done, I can retrieve that information with a pbpaste command. I wonder if this information is available to your trailing AppleScript action for inclusion in the display alert statement?
