Superior summoning feat and summoning mastery

[wingermage]

Superior Summoning
You can summon more creatures.

Prerequisites: Augment Summoning, caster level 3rd.

Benefit: Each time you cast a summoning spell that conjures more than one creature, add one to the total number of creatures summoned.
---------------------------------------------------------------------
Summoning Mastery (Sp): Starting at 1st level, a master summoner can cast summon monster I as a spell-like ability a number of times per day equal to 5 + his Charisma modifier. The summoner can use this ability when his eidolon is summoned. Only one summon monster spell may be in effect while the eidolon is summoned. If the summoner's eidolon is not summoned, the number of creatures that can be summoned with this ability is only limited by its uses per day. This ability otherwise functions as the summoner's normal summon monster I ability. Other than these restrictions, there is no limit to how many summon monster or gate spells the summoner can have active at one time. This ability replaces the summoner's normal summon monster I ability and shield ally.

Can I summon more creatures?

Then one could use empower or quicken spell like ability on it, though the actual level would not be max due to restrictions.

Check the magic section. Slas works just as spells except where noted. Augment and superior summoning works, as does spell focus. Devs have stated this. The only reason metamagic doesn't is lack of slots.

I know Augment was ruled to work, but where has superior been added?

Augment was ruled to work because spell-like abilities function exactly like spells with a few exceptions, none of which are "spell feats don't work on them".
