Use these names when naming attack sprites and attack hurtbox sprites. For example, your dash attack should consist of dattack_strip10.png and dattack_hurt_strip10.png.
These names should also be used when naming the default attack scripts, but any other scripts in the attacks folder will also be executed regardless of name, so you can have scripts like dspecial_air, fstrong2, or downward_angled_ftilt.
