How parameters gets pass from tool to AI Agent

[User687957]

During my practice on AI agent , I face something which is not easy to follow which is the way parameters output from tools as send back and use by the AI Agent

For example I have an AI Agent which is based on the 2 following tools:

I get a Tool named "Get Incident Description" (Action flow) :

• Input a parameter "incident_number"
• output a parameter "Description"
• AI instruction is : Get the Incident Description with the Incident Number
• Script

(function execute(inputs, outputs) {
 
    var result = {};
    var inc_gr = new GlideRecord("incident");
    inc_gr.addQuery('number', inputs.number);
    inc_gr.query();
    if (inc_gr.next()) {
        outputs.description = inc_gr.getValue('description');
    } else {
        outputs.content = "Unable to fetch requested incident record.";
    }
    
})(inputs, outputs);
​

Then I have an other tool "Update incident Description" :

• Input a parameters : number, description
  
• Script tool 
  

(function(inputs) {
    // only string inputs are allowed 
    // return outputs object where the keys in it are understandable by LLM
    if (!inputs) return {
        message: 'No inputs found, could not make Incident updates.'
    };
    var gr = new GlideRecord('incident');
    gr.addQuery('number', inputs.number);
    gr.setLimit(1);
    gr.query();
    if (gr.next()) {
        gr.description = inputs.description;
        if (inputs.description != '') {
            var updateStatus = gr.update();
            if (updateStatus) {
                return;
            }
            else {
                return {
                    message: 'Incident updates could not be made, update failed.'
                };
            }
        }
        else {
            return {
                message: 'No Incident updates available.'
            };
        }
    } else {
        return {
            message: 'No Incident found, could not update.'
        };
    }
})(inputs);

• AI instruction : Update the Description of the incident based on the incident number

Q1 : How the tool "Update incident Description" is getting the incident number from as variable are different and the only output for tool 1 is description

Q2 : How the AI agent receive the Description output ?

Q3 : from scripting, how the Input context is set ?

Thanks for clarification
