Noel broke the chain from her handcuffs, allowing her to move freely, but the magic sealing collar is still in place.

Those are skills rather than spells, which have no verbal component, and she mentioned they weren't affected by the magic seal. <Concealment> was hiding her presence, suppressing things like smell and sound to make her harder to find.
Looking back at the first chapter, the analysis and item box aren't listed as skills or magic, so they may be associated with the title "Traveler from Another World"? Not sure how that part of the system is working.
