The development of COSINE has shown that the agents with the same function have a lot of rules that are almost identical. This is not surprising, but it shows that instead of hand-coding the agents, a graphical knowledge acquisition tool can be built where the designer of a SiFA based design system enters knowledge that is specific to an agent and the rest of the agent is built automatically.
Work in this direction would mainly have practical importance. It would help to build large-scale SiFA systems. There would be some theoretical gain as well since this work would show what is common to groups of agents and help us understand SiFAs better.
