Stop Writing Tone Instructions. Layer Them. - Isadora Martin-Dye, Isadora & Co
Brand voice in AI agents fails on edge cases unless instructions are layered into a four-tier architecture instead of one prompt.
“I'm not programming a robot, I'm managing a brilliant intern with an incredibly high IQ and a terrible EQ.”
Isadora Martin-Dye argues that single system prompts for brand voice break on unanticipated turns because one prompt is forced to do four different jobs. She proposes a layered architecture—starting with an immutable identity layer and a situational mode layer—to keep AI agents on-brand in high-stakes, relationship-driven contexts. This is a practical engineering pattern for teams building customer-facing conversational agents where voice consistency is the product.
