    // @Player when the entity who triggered the change is a player.

    // @NPC when the entity who triggered the change is an NPC.
    //
    // @Context
    // <context.entity> returns the EntityTag of the warden which changed its anger level.
    // <context.new_anger> returns an ElementTag(Number) of the new anger level.
    // <context.old_anger> returns an ElementTag(Number) of the old anger level.
    // <context.target> returns the EntityTag who triggered the change (if any). (In practice, always present).

    // @Determine
    // "ANGER:<ElementTag(Number)>" to set the value of the anger level. Value must be between 0 and 150.
    //
    // @Example
    // on warden changes anger level:
    // - if <context.new_anger> >= 40 && <context.new_anger> < 80:
    //     - announce "Careful, the warden is agitated!"
