User commands¶
To define user commands, use the intent() function. This function allows you to complete tasks requested by users or answer the user’s questions.
In the intent() function, you must specify:
Pattern: the user’s phrase that invokes the command. You can specify one or more patterns in the
intent()function.Response: a response phrase or action that must be executed when the command is invoked.
In the example below, when the user asks: Who are you?, the intent is invoked and the Agentic Interface replies: I am your Agentic Interface:
intent('Who are you?', p => {
p.play('I am your Agentic Interface');
});
Command responses¶
To provide responses or execute actions for commands, use the following functions:
play(): use this function to provide a response to the user or send a command to the app
reply(): use this function to provide a response to the user
Play()¶
To provide a response to the user, add the play() function to intent() and define a response phrase:
intent('How can you help me?', p => {
p.play('I can provide information, answer questions and offer suggestions');
});
The play() function can also be used to send commands to the client app integrated with Alan AI. Such commands let you perform specific actions in the app, for example, navigate to another page, highlight UI elements on the screen and so on. This way, you can synchronize user commands and visuals and design a multimodal AI experience for your app.
To send a command, pass a JSON object containing the command name and any further information to the play() function. To handle the command in the app and execute the requested action, you must add a handler for commands received from the dialog script. For details, see onCommand handler.
intent('Open the product page', p => {
p.play({command: 'navigate', screen: 'product'});
p.play('Opening the product page');
});
intent('Go back', p => {
p.play({command: 'navigate', screen: 'back'});
p.play('Going back');
});
When you send a command to the app, you most commonly accompany this command with the Agentic Interface comment so that the user understands what actions are taking place at the moment.
If you place the command before the Agentic Interface message, Alan AI will send the command immediately when the intent is matched.
If you place the command after the Agentic Interface message, the command will be sent after the message has been provided.
For example:
// Sending a command when the intent is matched
intent('Open the product page', p => {
p.play({command: 'navigate', screen: 'product'});
p.play('Opening the product page');
});
// Sending a command after the message is provided
intent('Open the product page', p => {
p.play('Opening the product page');
p.play({command: 'navigate', screen: 'product'});
});
Note
To send a command to the app using Alan AI Agentic Interface, set the play options for the command to force:true. When you use the text interaction channel, the Agentic Interface button is inactive, and commands cannot be executed unless the force option is enabled. For details, see Play options.
