Agents need to be able to notice situations where there is the possibility of a conflict. This act of realizing a potential conflict is called conflict indication.
Conflict indication is a very simple task for the agents in the SiFA paradigm.
Each time an agent acts on its target by modifying it, the state of the overall system changes, therefore there is potential for a conflict. The way a possible conflict is indicated depends on to which one of the two general conflict categories the conflict belongs.
