Note that you can paste your Diagram in the PTA, and press the Piece Table button to get the HTML for a piece table including images and textual move descriptions, like the one I put in my 'Demotion' submission. The table there was entirely generated in this way, as all pieces were sliders, leapers or compounds of those. For more complex pieces the generated descriptions might not be perfect, and need some hand editing. But usually there aren't many of those, and what it generates for them might still be partly usable.

I tried it for your variant, and it produced thefollowing:
hussar
makes a lame (1,2) leap via the (0,1) square, or steps one square straight backward or sideways
lancer
makes a lame (1,2) leap via the (0,1) square, or steps one square diagonally backward
equesrex
steps one square in all 8 directions, or makes a knight's jump
camel-queen
makes a (3,1) leap, or slides in all 8 directions
striped-gryphon
steps one square diagonally and from there can continue to slide orthogonally outward, or makes a (3,2) leap
cobra-manticore
makes a knight's jump, slides up to 2 squares orthogonally, or jumps to the 2nd square orthogonally if that is empty and from there must continue to slide diagonally outward
paladin
slides diagonally, or makes a knight's jump up to 2 times in the same direction
zebra-nightrider
repeatedly makes a knight's jump in the same direction, or makes a (3,2) leap
marshall
slides orthogonally, or makes a knight's jump up to 2 times in the same direction
assasin
makes a (3,1) leap, or makes a (4,3) leap
ninja
jumps to the 3rd or 4th square diagonally, or makes a (4,1) leap
lightcannon
slides orthogonally to an empty square, or jumps over the nearest piece orthogonally for capturing only
heavycannon
jumps over the nearest piece orthogonally, or jumps over the nearest piece straight ahead for capturing only
mammoth
steps one square in all 8 directions, jumps to the 2nd square diagonally, jumps to the 2nd square orthogonally, jumps to the 3rd square orthogonally to an empty square, or jumps to the 3rd square diagonally to an empty square
The Heavy Cannon obviously confuses it, while it could have been smarter contracting the descriptions of the Mammoth (But the latter would have sounded better if the XBetza had described it as KSmT.) And it sometimes ignores that the piece is not fully symmetric.
