How To Evaluate Your Design System Documentation Partner?

During our benchmarking, we found three major issues while evaluating agencies for design system documentation:

Most design systems are built visually, but rarely documented with dev tokens, naming conventions, and usage instructions
There's often no Figma-to-Storybook or Zeplin-like workflow that integrates design into engineering
Agencies skip documentation updates post-build, leaving teams confused and disconnected from actual usage
