How our agents build on-brand pages with design.md

This post details the development of `design.md`, a public file that provides AI agents with consistent brand and design guidance for generating on-brand pages and reports. It describes the three-part system: `design.md` for guidance, a public stylesheet for design primitives, and an evaluation loop for iterative improvement. The post highlights the challenges of subjective design language and the importance of context for AI models, demonstrating how `design.md` and the evaluation process led to more consistent and on-brand outputs. It also introduces the concept of naming recurring generated-design patterns to help agents avoid them.
