Have the parser ignore everything not between the braces?
It already does that, it simply copies it back verbatim. That's the point of the parser - you can actually throw it a whole roleplay, like:
"Dodging left and right, Gregor prepared his [1|abc] and unleashed it just as his opponent came up for another attacker."
and the parser will parse that and spit out something like:
"Dodging left and right, Gregor prepared his
Lightning Bolt and unleashed it just as his opponent came up for another attacker."
