What its author says it does

Copied from the file, not written here

Tunes Next.js App Router application quality - next.config hardening, eslint-config-next flat config, strict mode and typed routes, RSC and use-client boundary hygiene, bundle analysis, image and font optimization. Use when the user asks to production-harden a Next.js app, fix hydration or use-client errors, or shrink a Next bundle. Not for generic Node linting, unit test setup, or npm packaging.

nextjs-quality

Applies App-Router-era Next.js quality practice — where generic Node advice and pages-router folklore actively mislead. The failures this skill fixes: models sprinkle use client until errors stop, configure generic ESLint instead of the Next ruleset, quote deprecated next lint-era workflows, and "optimize" bundles without measuring.

When NOT to use

  • Generic Node/TS lint outside a Next app → node-lint.
  • Unit/component test setup → node-testing.
  • Packaging a library → node-packaging; deploys/hosting → out of scope.
  • Writing app features → ordinary dev work.

Workflow

  1. Audit current state: Next major (the playbook version-gates what's stable vs experimental per line), next.config.*, lint setup, next build output as the baseline.
  2. Lint the Next way: eslint-config-next in flat config (the playbook has the current wiring — verify the next lint deprecation state for the installed major); its RSC/boundary rules are the point, don't swap them for generic configs.
  3. next.config hardening from the playbook checklist: reactStrictMode, typed routes (status verified per version), images config, output mode matched to the deploy target, source-map policy — each explicit, none by default-trust.
  4. Boundary hygiene (the hydration / use client complaint): find the actual offending imports; make client islands minimal; keep data fetching and secrets server-side (server-only where it protects); add the lint rules that catch regressions. Playbook has the common-causes checklist.
  5. Bundle work is measurement work: analyzer first, then the real levers — dynamic imports, server components for static parts, tree-shakeable imports, next/image + next/font — and re-measure; report the delta, not vibes.
  6. Verify after every change: next build green is the loop gate; type and lint gates stay on.

Output spec

An explicit hardened next.config, Next-native lint in force, no unexplained use client at module tops, measured bundle deltas for optimization asks, and next build passing — with anything version-experimental labeled as such.

Gotchas

  • use client marks a boundary, not a fix — adding it at the top of a big tree ships the tree to the client; islands, not blankets.
  • Hydration mismatches are usually non-deterministic render inputs (dates, random, locale) — the checklist finds them faster than console archaeology.
  • output: 'export' silently disables server features — deploy target first, config second.
  • Next majors move fast: the playbook version-gates typed-routes/lint specifics; re-verify against nextjs.org docs for the installed major.
