Governance

This one keeps your design system from turning into the Wild West as it scales. It walks you through SemVer classification (major vs. minor vs. patch), enforces a quality bar before promoting components from product to core, and makes sure deprecations get a proper runway with migration maps instead of breaking everyone's builds overnight. You'll want it when deciding whether renaming a token is a breaking change, setting up contribution workflows, or figuring out how to retire that button variant three teams still depend on. The verification step is solid: changelog entries, contrast checks, and a Python validator to catch broken token references before they ship.

Skill: Governance

Requirements

This skill needs the full UX/UI Agent Skills kit: the gates, the references and the design-system library. Install it with npx ux-ui-agent-skills@3.1.0 init or as the Claude Code plugin. npx skills@1.7.6 add copies the skill folder and nothing else. Installed that way, this skill runs in guidance-only mode: no gate runs, so it gives no verdict.

Step 0: is the kit here? Check once: ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING On KIT_MISSING, open your reply with: "Guidance-only mode: the UX/UI Agent Skills kit is not installed here, so no gate ran and nothing below is measured." Then work from this file and general practice, under three rules. Do not guess or cite the contents of a kit file you could not open. State no measured number (no contrast ratio, no N/N, no "passes WCAG"): write "not verified" where one would go. End with a line Skipped (kit not installed): that names every gate script this file tells you to run, then the install command above.

Keep the system consistent as it grows. Apply versioning, contribution, and deprecation rules.
