Task completion for natural language input

One or more techniques and/or systems are provided for facilitating task completion. For example, a natural language input (e.g., "where should we eat") may be received from a user of a client device. The natural language input may be evaluated using a set of user contextual signals, opted-in for exposure by the user for facilitating task completion, to identify a user task intent. For example, a user task intent of viewing a local Mexican restaurant menu may be identified based upon a social network post of the user indicating that the user is meeting a friend for Mexican food. Task completion functionality may be exposed to the user based upon the user task intent. For example, a restaurant app may be deep launched to display a menu of a local Mexican restaurant.
