Generate variables from one skill(Native/Semantic) output for pipeline execution.

[mohammedtabish0]

While running the skills in a pipeline the generated output of one skill is put into the variable INPUT in the ContextVariables(calling the context variable's update method) and then before running the next skill prompt template engine will create blocks and replace the input variable with the last skill execution output. But in example let's say

skillOne -> Generates some context and set the output in variable1 
skillTwo -> Generates some context and set the output to variable2

skillThree -> The prompt looks like " Write a paragraph on topic {{variable1}} to create XXX and use {{variable2}} as the different inputs" 

So instead of calling the skills separately and setting the variables in context

outputOne = kernel.RunAsync(skillOne, input);    
outputTwo=  kernel.RunAsync(skillTwo, input);    

contextVariables.Set("variable1", outputOne );   

contextVariables.Set("variable2", outputTwo);    
kernel.RunAsync(skillThree, contextVariables);

What I want want to do is kernel.RunAsync(input, skillOne, skillTwo, skillThree)

The config of skills should handle the information of output variables. Just like we can mention input variables for a skill we should be able to add output variables and the engine should handle the generation of output variables and setting them into the context. This might be not feasible to do as we might face problems like generating multiple output variables from selecting the completed text but wanted to hear more thoughts on this.

There's definitely work we want to do to improve the visibility of outputs from functions.

In the short term, I'd try using the Plan object.

var prompt = "Write a {{$input}} on topic {{$variable1}} and use {{$variable2}} as the voice of the {{$input}}.";

    // Import Skills
    var summarize = kernel.CreateSemanticFunction(prompt);
    var testSkill = kernel.ImportSkill(new TestSkill(), "TestSkill");

    // Create PLan
    Plan plan = new("Create a text using skills");
    plan.AddSteps(testSkill["SkillOne"], testSkill["SkillTwo"], summarize);

    plan.Steps[0].Outputs.Add("variable1");
    plan.Steps[1].Outputs.Add("variable2");

    // Execute Plan
    var result = await plan.InvokeAsync("poem");
    Console.WriteLine(result.Result);`
