Well, maybe refactoring would make sense and call it

ON_MISSING_BUT_KNOWN_EXECUTABLE=run/install/ask/ask_run/ask_install/ask_once_run/ask_once_install
where 
  run => runs
  ask => asks whether to run or run and install
  ask_install => asks to install
  ask_run => asks to run

or similar. For instance I'd prefer "ask once per app" eventually
because I could have made a typo.
