Skill: Governance

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

Steps

  1. Read 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/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 (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 scripts/validate_tokens.py passes; contrast re-checked if colors changed.

Individual skills in this repo

This repo contains 7 individual skills — each has its own dedicated page.

plugin87/design-tokens

Generate, extend, or audit design tokens in DTCG format with the 3-tier architecture (primitive → semantic → component). Use when the user wants a color palette, type scale, spacing/shadow/radius/motion tokens, multi-brand theming, or wants to validate token files. Covers colors, typography, spacing, shadows, borders, breakpoints, motion, gradients, opacity, blur, sizing, states, theming.

plugin87/image-to-code

Turn a reference image, screenshot, or mockup into token-driven, accessible code — infer the design system from the reference (palette, type scale, spacing, radius, layout archetype), map it to the 3-tier tokens, rebuild it, then verify with the kit's gates. Use when the user provides a design/screenshot and wants matching UI code.

plugin87/performance

Optimize UI performance against Core Web Vitals — LCP, INP, CLS — with loading/code-split strategy, layout-shift prevention, and animation performance rules. Use when the user wants to improve speed, fix jank or layout shift, hit Web Vitals budgets, or make a UI feel fast on low-end devices.

plugin87/prototype

Move an idea up the fidelity ladder (content-first → wireframe → low-fi → high-fi → code) with a validation plan at each level, plus user-journey mapping and usability-testing scripts. Use when the user wants to prototype, wireframe, map a user flow, or plan/run usability testing.

plugin87/redesign

Upgrade an existing website or app to premium quality without breaking functionality — audit the current design, identify generic/AI tells, then apply taste and system rules surgically. Use when the user wants to improve, modernize, polish, or "make better" an existing UI/codebase.

plugin87/token-build

Set up or run the token build pipeline — transform the DTCG tokens/*.json (source of truth) into platform artifacts (CSS variables, Tailwind @theme, JS/TS, iOS Asset Catalog, Android, Compose) with Style Dictionary / Tokens Studio / W3C DTCG export. Use when the user wants to generate platform theme files from tokens, wire token CI, or multi-platform token output.

plugin87/ux-writing

Write or review UI copy — buttons, errors, empty states, microcopy, notifications, labels — using the voice & tone system (clear, concise, useful, human, honest) with the what→why→how error formula and inclusive-language rules. Use when the user needs interface copy, error messages, empty-state text, or a copy review.
