react-nextjs-frontend

react-nextjs-frontend is a skill for Claude Code, Codex from vaquarkhan/Fullstack-development-agent-skills. It costs 48 tokens per session (139 once invoked), scanned A, original, MIT.

A set of frontend defaults for React and Next.js applications written in TypeScript. It covers page navigation, server and browser rendering, shared interface parts, loading states, errors, and accessibility.

In plain words
What is it for?
Use it to build React or Next.js pages, choose rendering approaches, organize reusable interface components, handle route states, and check accessibility during code review.
Why use it?
It gives the interface a consistent structure and clarifies which code runs on the server or in the browser. This helps avoid unclear state handling and missed loading, error, or accessibility needs.

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

react-nextjs-frontend 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 3d 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.

React Next.js Frontend Preset

Defaults

  • TypeScript strict mode
  • Server components by default, client components only when needed
  • Centralized design tokens and UI primitives
  • Route-level loading and error states

  • api-contract-first-development

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.
