nextjs-fullstack is a skill for Claude Code, Codex from DominikTobureto/awesome-grok-build. It costs 37 tokens per session (392 once invoked), scanned A, original, MIT.

A guide for building full-stack applications with Next.js, a React framework for pages, server code, and API endpoints. It covers routing, authentication, databases, caching, deployment, and tests.

In plain words
What is it for?
Adding Next.js pages and routes, forms, server actions, API routes, authentication, database integration, loading and error states, and build or test checks.
Why use it?
It helps keep browser code, server code, data access, security checks, and caching in the right places.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nextjs-fullstack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Next.js Fullstack

Ship Next.js features with correct boundaries between server, client, data, and UI.

Grok Build Mode

  • Use Plan Mode for routing, auth, persistence, caching, or data-fetching changes.
  • Use subagents for broad changes:
    • routes: app router structure, layouts, metadata.
    • data: DB queries, server actions, validation.
    • client: components, state, forms, accessibility.
    • tests: unit/e2e/build verification.
  • Arena-style comparison: compare server action vs API route vs client-only approaches and choose by security, simplicity, and cache behavior.

Workflow

  1. Detect Next version, package manager, styling, auth, DB, and test setup.
  2. Keep server-only code out of client components.
  3. Validate inputs on the server.
  4. Respect existing caching/revalidation patterns.
  5. Add loading/error/empty states.
  6. Run the narrowest relevant checks:
    • npm run lint
    • npm run typecheck
    • npm run build
    • project tests.

Rules

  • Do not leak secrets into NEXT_PUBLIC_*.
  • Avoid unnecessary client components.
  • Do not mutate data without auth and ownership checks.
  • Keep forms progressive and resilient.
  • Use existing UI primitives and route conventions.

Example Prompts

Use nextjs-fullstack. Plan a server-action implementation for this feature, including validation, auth, tests, and loading/error UI.
Review this Next.js diff for server/client boundary bugs and cache invalidation issues.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
