My assessment (based on reliable information) is different. What I have heard:
1 - They indeed crossed the border to attack some forward posts (whether they wanted to capture them is not clear)
2 - PA knew about their movements and our soldiers vacated the posts in order to minimize the damage and engage them near the LoC
3 - IA was so unaware about PA strategy that they couldn't handle the unexpected attack. A lot of them died near LoC (25-50 meters here and there)
4 - Some of the soldiers were captured (only one is being reported in media although PA hasn't confirmed about that 'one' as well)
5 - PA didn't allow IA to pick the bodies/ injured for several hours.
6 - India didn't use any elite force in this operation. Rashtriya Rifles participated only.
Point number 6 is very important. They wanted to check the preparation of PA and didn't want to involve their elite force. They also wanted to check the internal (opposition parties) and external (international) reaction to this operation. The operation was failed miserably but since they wanted to check the reaction (specially international reaction), they announced it as successful surgical strike. They have made everyone (in India, Pakistan and rest of the world) believe that this concept is not alien. We should expect it every now and then.
I think, they will now do another attempt in the coming months, if not days. This time they may use their commandos and other special forces. They have already checked the reaction of the world and for them it was just acceptable. They haven't, however, experienced the full reaction of Pakistan yet as they were unable to achieve what they wanted. If they do any misadventure in future, PA will retaliate very aggressively. This is where their calculation is a little bit wrong as PA will not let anyone return this time.
