Overview
Design system versioning fails in two directions. Systems that never break anything accumulate technical debt until the system is so constrained it cannot improve. Systems that break things without warning destroy team trust until product teams stop upgrading — pinning to old versions and building around the system instead of with it.
The Design System Versioning & Breaking Change Protocol Prompt builds the versioning discipline that allows a design system to evolve aggressively while giving dependent teams the predictability they need to plan upgrades. It defines what constitutes a breaking change, how breaking changes are communicated, and what a migration guide must contain to be actionable rather than aspirational.
What you get: - Semantic versioning applied to design systems: what constitutes a major, minor, and patch change in a component library - Breaking change classification: the decision tree that determines whether a change is breaking before it ships - Migration guide standard: the format every breaking change must follow to be mergeable - Release cadence model: the release schedule that balances system evolution with team upgrade capacity - Changelog standard: the format that makes changelogs useful to both engineers and designers - Deprecation protocol: the full lifecycle from deprecation notice to removal
Built for: design system leads and design engineers managing a versioned component library with multiple dependent teams.
