Who is responsible for design tokens?

Design token governance works best when split by function: designers manage primitives, while engineering handles transforms and platform-specific outputs.

What: The strategy proposes a shared governance model where designers own the raw values, a cross-functional team manages the semantic layer as an API, and engineering automates the deployment pipelines.

Why it matters: Centralized ownership often becomes a bottleneck; treating tokens as a software dependency with automated breaking-change detection is the most scalable path for large design systems.

Takeaway: Implement automated CI checks that flag deleted or renamed semantic tokens in your design system repository to prevent accidental breakages.

Deep dive

Primitive Tokens: The foundational values like color hex codes or spacing variables.
Semantic Tokens: Tokens that describe purpose rather than value, e.g., button-bg-primary instead of blue-500.
Governance Layer: The process of controlling how tokens are updated, versioned, and documented.
Transformation Layer: Scripts that convert design JSON/YAML tokens into platform-specific code (e.g., Swift, CSS, Android XML).
CI/CD Integration: Using pipelines to validate that changes in token definitions do not break downstream UI components.

Decoder

Design Tokens: Named entities that store design decisions (colors, typography, spacing) to ensure consistency across different platforms and products.

Original article

Design token ownership works better when responsibilities are divided according to the type of change rather than handed entirely to either designers or engineers. Designers can own primitive values, a mixed design-systems team can govern semantic tokens as a public API, and engineering can own transforms and platform-specific output. Automated checks can protect this structure by allowing value changes while flagging deleted or renamed semantic tokens that could break components and require migration.
