For anti-fighter it has bracketting/AA capital lasers, LRMs, and barracuda missiles. For antimissile, it has AMS. For Antiship, it has the classic 4 HNPPC bays, and the capital lasers, along with killer whales/white sharks. A broadside is 12 NL-55s, 8 HNPPC, 4 Capital Missiles. If the ships have closed enough, the anti-fighter LRMs can be fire off to confuse enemy PDS, and possibly make it more likely for the ship's own capital missiles to sneak through the enemy defenses (since few clan warships have AMS of their own, their PDS is much easier to wear down each turn).
Quarters are as spartan as they come, with even officers having minimum space. A small escort of 10 fighters 2 dropships are carried. The Watch has heard that after this initial prototype, the plans were altered somewhat and future versions may have better accommodations and more fighters, and even a battle armored marine contingent, at the cost of less cargo space.
The ship's armor is comparable to battleships on the nose and aft, and on the side it has some of the thickest armor plating on any ship produced by the clans to date. It carries enough fuel in it's tanks for only a single month of operation, however, quite often more fuel is carried in the cargo bay as well.
I figure, you probably already have fluff for it, so I'll leave the rest to you.
Edit, fixed an error in the design.
