This is the folder where your project's hooks live. Hooks are Node modules that add functionality to the Sails core. For more information, see Concepts > Extending Sails > Hooks.
An example of this directory can be found in our sample app repo, here.
The Sails framework is maintained by the core team with the support of our contributors. We created Sails in 2012 to assist us on Node.js projects. Naturally we open-sourced it. We hope it makes your life a little bit easier!
