2. cutting out unnecessary (already known, implied or repeated information)
This devise gem is the gem responsible for user authentication and functions related to that. It is rack-based and is used well with Rails application software.
“is responsible for user authentication and related functions. It is rack-based and compatible with Rails application software.”
This option consistently describes this gem using related description words “rack-based” and “compatible.” It also cuts out repeated information such as “the gem[gem is the gem]” and implied information such as “related to that [functions related to that].” Replacing “used well” with “compatible” mentioned previously, also cuts out unnecessary information.
“is responsible for user authentication and related functions. It is rack-based and works with Rails application software.”
This option, like the one above, cuts out repeated information such as “the gem [gem is the gem]” and implied information such as “related to that [functions related to that].” But, this option does not consistently describe this gem because it uses a description word, “rack-based” and the action word, “works” instead of using consistent description or action words.
“is the one responsible for user authentication and related functions. It is rack-based and a compatible partner with Rails application software.”
This option, like the one above, does not consistently describe the gem because it uses a description word, “rack-based” and a thing, “partner,” instead of using consistent description words or action words. This option also adds implied information such as “the one [gem is the one].” Also, adding “a compatible partner” after the description word as previously mentioned, is less concise than adding another description word like “compatible.”
