Unified design foundations — design system architecture, tokens, component specs, visual principles, creative vision, figma integration, plus brand design system loader (66 real brands via DESIGN.md). Absorbs design, design-system, design-systems, design-principles, design-router, creative-vision, figma, design-md.
Render, summarize, and present markdown documents and structured content in multiple output modes
Ultra UI skill - combines Google's DESIGN.md spec (machine-readable design tokens) with the ui-ux-pro-max knowledge base (91 styles, 161 palettes, 73 font pairings, 161 products, 104 UX guidelines, 25 chart types). Generates lint-clean DESIGN.md files, validates token references and WCAG contrast, exports Tailwind/DTCG tokens, and diffs design systems version-over-version.
Initialize UltraThink capabilities in the current project directory
Org-Bench Google-bipartite winning mechanism — the 4-section design-doc gate that every non-trivial change passes through. Use when the Director defines new work, when an Integrator reviews a lane (code/quality/devops), when the Director approves, or when a Worker is about to start coding and needs the spec. Tools live in the `design-doc` MCP server. Triggers on phrases like "design doc", "design review", "approve revision", "lane verdict", "what does this issue require", "is this approved yet".
Web scraping with anti-bot bypass (Cloudflare Turnstile etc.), stealth headless browsing, adaptive selectors, and concurrent crawls. Use when the user asks to scrape, crawl, or extract data from websites; the built-in WebFetch fails; the target has anti-bot protections; or the work needs JavaScript rendering. Prefers the registered MCP tools (mcp__scrapling__*) over raw Python so token cost stays low.

Comprehensive SEO for web apps. The bulk of the implementation lives in references/ — load the one(s) relevant to the user's task. Templates in assets/templates/ are ready-to-paste JSON-LD blocks parameterised on common fields.
| Task | Reference |
|---|---|
| Per-page metadata, OG tags, Twitter cards in Next.js | references/nextjs-metadata.md |
| Pick the right schema.org type + paste JSON-LD | references/jsonld.md (+ a template from assets/templates/) |
| Generate sitemap.xml or robots.txt | references/sitemap-robots.md |
| Fix LCP/INP/CLS regressions | references/core-web-vitals.md |
| Audit content quality (Experience/Expertise/Authoritativeness/Trust) | references/eeat.md |

The script:
<title>, <meta description>, OG tags, canonical| Gate | Why |
|---|---|
metadataBase set on root layout | Without it, OG image URLs resolve relative — broken on social shares |
| Canonical URL on every page | Prevents duplicate-content penalties |
description 50–160 chars | Outside this range Google often rewrites your snippet |
og:image 1200×630 + ≤300KB | Large/wrong-aspect images don't render in feeds |
alt on every content image | a11y + image search ranking |
| LCP < 2.5s on mobile 4G | Below this is a Web Vitals fail and a CrUX field-data drag |
| Unique title per page | Duplicate titles get clustered in SERPs |
<Head>. Pick one; Metadata API wins for App Router.</script> inside JSON-LD strings. Use dangerouslySetInnerHTML with sanitised input.robots.txt blocking /_next/static/. Don't — Google needs your CSS/JS to render correctly.noindex and then linking to the page from elsewhere. Either commit to noindex or remove the inbound links; mixed signals hurt.next/script with strategy="lazyOnload" for analytics.
