* Test commands for proper names and search terms Assert that the `Command.name()` is equal to `Signature.name` Check that search terms are not just substrings of the command name as they would not help finding the command. * Clean up search terms Remove redundant terms that just replicate the command name. Try to eliminate substring between search terms, clean up where necessary.
