You can use a script to call a custom skill.

## Before you begin

Role required: admin

## Procedure

1. Navigate to AllSystem UIUI Actions.
2. Create a UI action.  
   For more information on creating UI actions, see [Create a UI action](https://www.servicenow.com/docs/access?context=t_EditingAUIAction&version=xanadu&pubname=xanadu-platform-administration&ft:locale=en-US).
3. Add your script.  
   The following script is an example. You can replace the variables with your data.

       var inputsPayload = {};

       // create the payload to deliver input data to the skill

       inputsPayload['input name'] = {

         tableName: 'table name',

         sysId: 'sys_id',

         queryString: ''

       };


       //create the request by combining the capability sys ID and the skill config sys ID

       var request = {

           executionRequests: [{

               payload: inputsPayload,

               capabilityId: 'capability sys id',

               meta: {

                   skillConfigId: 'skill config sys id'

               }

           }],

           mode: 'sync'

       };


       //run the custom skill and get the output in a string format
       try {
       var output = sn_one_extend.OneExtendUtil.execute(request)['capabilities'][request.executionRequests[0].capabilityId]['response'];
       var LLMOutput = JSON.parse(output).model_output;
       } catch(e) {
        gs.error(e);
        gs.addErrorMessage('Something went wrong while executing the skill.');
       }
       action.setRedirectURL(current);
