mateonunez.co
My personal site. Public, SEO-driven, accessibility-first. Public skills (result-not-throw, vertical-slices, node-native-tests, single-tool-per-job) apply here too — this skill records what's site-specific.
Stack invariants
- Next.js 16 App Router. No pages router.
- React 19 with React Compiler enabled. No manual
useMemo/useCallback unless profiling demands it.
- Tailwind CSS v4.
clsx + tailwind-merge via a cn() helper. CVA for component variants.
- MDX for articles. Frontmatter is the source of truth for SEO metadata.
- No test suite. Linting is the gate.
pnpm lint must pass.
- Biome 2.x with the standard config (single quotes JS, double quotes JSX, 2-space, 120 width, semicolons, trailing commas all).
- Path alias:
@/ → project root.
Conventions specific to this repo
- Conventional Commit scopes:
a11y, seo, spotify, blog, ui, dependencies, agents. Use one of those — don't invent new scopes here.
- Server data: React
cache(). Client data: SWR. Don't mix.
- Spotify: OAuth refresh flow with in-memory cache. Don't add a database — the in-memory cache is intentional.
- Images: WebP/AVIF via
next/image. Decorative alt="", content alt="…".
Anti-patterns specific to this repo
- Adding a test runner. I don't test this site. The bar is "lint passes + manual smoke". Don't propose Jest, Vitest, or Playwright unprompted.
- Adding a CMS. MDX in-repo is the CMS. No Contentful, no Sanity.
- Persisting Spotify tokens to a database. In-memory only. The refresh flow is built around that.
- Bypassing the
cn() helper for class composition. Use cn, not raw template strings or clsx directly.
outline: none without a replacement. WCAG 2.1 AA bar applies — see the a11y-default-review skill.- JSON-LD changes without updating the corresponding test fixture in
references/features-seo.md if one exists.
