Everything is a command here, and you can assign them anywhere. Commands will be assigned to specific characters to enable them to use those commands. The script will let you add and remove commands from characters on the fly.

Everything actually done in battle is a Skill. Whenever a menu for a character to take action comes up, all their possessed skills are listed and filtered. Skills can be set to a specific command here (like magic, technique, or attack) and then they will only show up in the list for that command. Skills can also be filtered by element.

Elements have the familiar "link to weapon type" flag so that the character must have a weapon equipped that has all the same weapon types as the skill for the skill to appear. If the character is dual wielding weapons and one of them doesn't have all the required elements the character will only attack with the one that does.

If the list result has only one skill in it, selecting the command immediately proceeds to selecting a target or taking action. The user is shown what this only skill is when hovering over the command. This is how the "Attack" command is made- you then define the skill that represents a basic attack. This unifies all the battle calculations so there is simply an action and an effect. You could get rid of "basic attack" by just having a variety of skills.
