Governance skill

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.

Steps

1. Read ${CLAUDE_SKILL_DIR}/../../../workflows/governance.md (SemVer table, contribution workflow, deprecation policy, change comms).
2. Classify the change: major (breaking: renamed/removed token or prop, changed anatomy/default), minor (additive: new token/component/variant/optional prop), patch (fix: contrast/bug/doc/value tweak in tolerance).
3. For a new component/token: confirm it serves a real, repeated need (≥ 2 places) before promoting product → candidate → core. Design it to the full quality bar (${CLAUDE_SKILL_DIR}/../../../.claude/rules/components.md → Component Quality Bar).
4. 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.
5. 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.
