Link checker run: removed walmart-one (dead URL)
- Ran scripts/check-gallery-links.mjs against all 74 entries. Sandbox network policy returns 403 for most external domains so most warnings are noise — but two entries returned connection-level errors (DNS / refused), which is a different signal entirely.
- Removed walmart-one (https://design.walmart.com/) — failed in two independent tests (curl smoke test earlier, link checker now). Walmart's Living Design appears to be offline.
- Kept hashicorp-helios (https://helios.hashicorp.com/) for now — single connection failure could be sandbox-specific to hashicorp.com. Verify locally; remove if it stays dead.
- Gallery is now 73 entries.

Gallery: 10 missing systems added + logo fixes
- Added 10 well-known public design systems missing from the gallery: Pajamas (GitLab), Backpack (Skyscanner), Helios (HashiCorp), Geist (Vercel), PatternFly (Red Hat), Lexicon (Liferay), Stacks (Stack Overflow), Wonder Blocks (Khan Academy), HDS (City of Helsinki), Ontario Design System.
- Gallery is now 74 entries.
- Fixed broken logo for square-design (was an Elasticsearch CTF asset, replaced with the correct Square logo).
- Replaced weak logo sources for chakra-ui (was logowik third-party host) and nextui (was a wide banner image) with their GitHub org avatars.
- Added fallback entries in logo-fallbacks.ts for all 10 new systems so curated logos win over inline gallery URLs.
- Note: external comparison sites (designsystemsrepo, designsystems.surf, adele.uxpin.com) are blocked from this sandbox so the additions came from training-data familiarity. Run scripts/check-gallery-links.mjs locally to validate.
May 7, 2026
Gallery link audit + clean-up
- Removed 15 invalid gallery entries: 10 corporate-homepage links with no actual public design system (Chase, Wells Fargo, Citi, Amex, UnitedHealth Group, Cambridge, NYTimes, Netflix, CoinGecko, Walmart corporate URL), 4 duplicates (salesforce-lds, shopify-polaris, ibm-carbon, github-primer), and 1 dead project (Lonely Planet's rizzo).
- Gallery is now 64 entries — every one points at real, navigable design system documentation.
- Shipped scripts/check-gallery-links.mjs — concurrent HEAD/GET checker with redirect-follow, browser UA, and 401/403 tolerance. Run with `node scripts/check-gallery-links.mjs` before merging gallery PRs.
- CONTRIBUTING.md updated with the URL-quality rule (point at real DS docs, not corporate marketing pages) and the link-checker workflow.

Phase 4.4 lands — MCP server
- @designsystems-one/mcp shipped as packages/mcp. Working stdio MCP server with four tools: list_design_systems, get_design_system, list_glossary_terms, search_glossary.
- Wraps the public JSON API at /api so agents see structured tools instead of raw HTTP. DESIGNSYSTEMS_API_BASE env var points the server at a preview deploy or local dev.
- Stdio handshake verified end-to-end: initialize → tools/list returns the four tool schemas. Ready to wire into Claude Code or Cursor via .mcp.json.
- Source + Claude Code / Cursor config snippets documented in packages/mcp/README.md and surfaced on the /registry page.
- npm publish is the remaining step — no blockers, just a publish flow decision.

Phase 4.2 + 4.3 + 4.5 land — the AI-native plumbing
- shadcn-compatible component registry at /r — utils, button, input, card. Agents install with `npx shadcn@latest add https://www.designsystems.one/r/button`.
- Public JSON API: /api/design-systems and /api/design-systems/[slug] expose the gallery and rich breakdowns; /api/glossary exposes all 40 terms. CORS-open, statically generated, fully cacheable.
- AgentCallout component live on the token-generator page with copy-paste install commands for the shadcn CLI, Cursor/Claude Code, and the W3C tokens flow.
- Glossary terms moved to lib/glossary-terms.ts so the page and API render from the same source.
- /registry docs page with install instructions and the live item list.
May 7, 2026
Phase 0 + 1 + 2.1 + 4.1 + 5.1 land
- 10 more design system breakdowns: Fluent, Ant Design, MUI, Chakra, Mantine, Tailwind UI, Radix, Paste, USWDS, BBC GEL — total rich coverage now 20.
- Logo audit: fixed Lightning Design System (was UHC by mistake) and Foundation (was a feature icon). The getLogoUrl helper now prefers curated fallbacks.
- Blog scaffold: /blog index, /feed.xml RSS endpoint, post manifest. Posts come next.
- Public roadmap and changelog at /roadmap and /changelog.
- W3C-spec design token export added to the Token Generator (Phase 4.1).
- /about removed per scope cut; founder context lives on /contact.
May 7, 2026
Educational hub foundation
- Strategy plan saved to docs/strategy.md as the canonical reference for the hybrid-C positioning.
- Per-design-system breakdown pages launched for 10 anchor systems (Polaris, Carbon, Material 3, Primer, Lightning, Atlassian, Spectrum, shadcn/ui, Cloudscape, GOV.UK).
- Glossary published with 40 plain-language entries.
- Repo open-sourced: MIT license, CONTRIBUTING, code of conduct.
- Dynamic OG image route at /api/og.
- Schema.org JSON-LD on /design-systems index, /glossary, and per-system breakdowns.
May 7, 2026
Repositioning + redesign sweep
- Hero rewritten: 'DESIGN SYSTEMS / EXPLAINED / FOR PEOPLE WHO SHIP'. Educational frame committed to.
- Homepage tool grid restructured as an asymmetric bento with bottom-pinned CTAs and hover transforms.
- Universal button states upgraded with active:scale-[0.98] press feedback.
- Globals base layer: text-wrap balance/pretty, scroll-behavior smooth, tabular-nums.
- Skip-to-content link in layout.
May 6, 2026
AI Assistant placeholder removed
- Deleted the fake AI Assistant routes (/ai-assistant and /tools/ai-assistant). Real Claude API-backed assistant comes back in Phase 4.6.
- Cmd-K site search wired into the navigation, indexing all sections, tools, foundations, guidelines, and design system breakdowns.
May 5, 2026
Week 1 stop-the-bleeding
- Deleted three placeholder tool routes (icon-browser, media-library, ux-writing-templates).
- Rebuilt the code-generator around static templates (no Figma flow, no client-side credentials).
- Wired up dark mode end-to-end (ThemeProvider, theme toggle in nav, dark variables across all pages).
- Fixed the font system — dropped dead Geist/Source Serif imports, repointed --font-sans.
- Re-enabled Next.js image optimization across the app.
