    05 / OVERVIEW

    A judgment your code can use.

    SPX-CD turns context and candidate actions into typed decisions. Choose an action, select a set, estimate a yes/no probability, or score an ordered scale. The application can use the result directly.

    In a browser agent, CD decides which candidate action fits the goal. Browser tools perform the click, enter the text and observe the next state. Repeating this loop connects individual judgments into a workflow.
