Capability Node

A capability node is a unit in a graph that represents a specific function or action. It takes input, processes it, and produces output. Each node has an ID and a list of connected nodes, which are called its "out-degree." Nodes can be designed to perform various tasks, such as adding numbers, transforming data, or interacting with external systems.

For example, consider a node that takes two numbers as input and returns their sum. Another node might take a text string and return its capitalized version.
