@Ajay, the source for the sniffs is indeed WPCS.

Currently its using predominantly the wordpress-core sniffs from the project and also relevant sniffs from wordpress-vip that pertains to performance. The team carefully reviewed the selected sniffs and categorised it into "security", "performance" and "standards". So some sniffs have a higher weighting than others.

As mentioned in the article, the weighting document will be made available so that the community can decide what it should be. Our's is just first draft.

The WPCS project is really the source of inspiration for Tide.
