You have to read the whole error message, not just assume it failed
irrecoverably:
( scratchpad ) \ <file-reader> help
<interactive>:1
\ <file-reader> help
^
Word not found in current vocabulary search path
"name" "<file-reader>"
The following restarts are available:
:1 Use the word IN: io.files : <file-reader> ( path encoding -- stream )
Type :help for debugging help.
( scratchpad ) :1
<file-reader> ( path encoding -- stream )

stream an input stream

If a word cannot be found in the current search path, the parser throws
an error but the error lists all vocabularies that have a word with this
name. You can invoke one of the restarts (like I did above with :1) to
use that vocabulary.
