Forms are not just data collection interfaces. They are the validation and constraint engine. Every field type, required rule, conditional logic rule, and cross-field constraint encodes a business rule in structure. When an AI agent submits a form headlessly, it gets the same validation a human gets — and richer, more actionable error feedback than any raw API or database write would provide. This is what makes agents smarter, not just faster.
