description: Govern how the design system evolves — SemVer for tokens/components, the contribution workflow, deprecation policy, and change communication. Use when the user wants to add/promote/deprecate a component or token, decide a version bump, set up a contribution process, or keep the system from fragmenting.
invocation: was not a field Claude Code reads - unknown frontmatter keys are
ignored without an error, so these six were auto-invocable the whole time they
were marked user-only. This is the field that actually does it.

Skill: Governance
Step 0 — is the kit here? This skill reads files from the kit. Check once:
ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING
On KIT_MISSING only the skill folders were installed, which is what
npx skills add does. Say so plainly, point the user at
npx ux-ui-agent-skills init or the plugin install, and stop. Do not guess the
contents of a file you could not open.
Keep the system consistent as it grows. Apply versioning, contribution, and deprecation rules.
Steps
- Read
${CLAUDE_SKILL_DIR}/../../../workflows/governance.md (SemVer table, contribution workflow, deprecation policy, change comms).
- Classify the change: major (breaking — renamed/removed token or prop, changed anatomy/default), minor (additive — new token/component/variant/optional prop), patch (fix — contrast/bug/doc/value tweak in tolerance).
- For a new component/token: confirm it serves a real, repeated need (≥ 2 places) before promoting product → candidate → core. Design it to the full quality bar (
.claude/rules/components.md → Component Quality Bar).
- For a deprecation: mark with reason + replacement + removal version; keep working ≥ 1 minor cycle; provide a migration map (
${CLAUDE_SKILL_DIR}/../../../design-systems/crosswalk.md style); remove only in a major.
- Wire any new file into
CLAUDE.md (File Reference Map + relevant table/router) and add a changelog entry.
Verification (definition of done)
- Change has a SemVer level and a changelog entry.
- Removals have a deprecation window, a replacement, and a migration table.
- New spec meets the 8-state + a11y + token-mapping bar and is reachable via the router.
python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py passes; contrast re-checked if colors changed.
