Example Scenario

The user and the agent are standing in a room with an enemy.
The user types in Kill the agent!
This command is passed to NLU which returns the frame Kill (object enemy)
The agent identifies the goal (kill) and a type that is associated with it (enemy).
The agent senses only one enemy in the environment so it resolves the goal kill object to the enemy in the environment.
The agent now has a valid goal and says as much to the user.
The competence module for KILL_ENEMY is activated and activation is spread to its precondition OWNS_GUN.
This in turn spreads activation to GET_GUN, and the agent states the new goal and goes about getting a gun.
Once it has the gun, OWNS_GUN is fulfilled, and the agent goes about killing the enemy.
