It means you are installing a complete group of packages, not just one package.

Try using man ;)

man yum - search for @:

      install
              Is  used  to install the latest version of a package or group of
              packages while ensuring that  all  dependencies  are  satisfied.
              (See  Specifying package names for more information) If no pack‐
              age matches the given package name(s), they are assumed to be  a
              shell  glob  and  any  matches  are  then installed. If the name
              starts with @^ then it is treated as an environment group (group
              install  @^foo),  an  @  character  and  it's treated as a group
              (plain group install).

For your group:

yum groupinfo development-tools
