/design-workflow

The project's root DESIGN.md is the single canonical design source (front-matter tokens are normative; prose sections explain application). This skill is process-only and project-agnostic: every token value, visual priority, exception, and anti-pattern lives in the consumer project's DESIGN.md, never here. agile-design consumes the same file on the prototype side; this skill owns the production-code side.

Project root

All paths are relative to the project being worked on, not the agent's CWD. The governing DESIGN.md is the one at that project's root. Never create or treat a secondary design file (.stitch/DESIGN.md, subfolder copies) as canonical. With --project <path>, prepend it.
