When I rotate my robot clockwise, should the yaw be increasing or decreasing? I noticed it turns the opposite direction when running slam_mapping in rviz.

See REP 103 for coordinate system conventions. In general, most coordinate frames follow those conventions, unless otherwise specified.

The short answer is that counter-clockwise is positive change in yaw in a frame that follows REP103 conventions.

"By the right hand rule, the yaw component of orientation increases as the child frame rotates counter-clockwise"
