react-advanced

Advanced React rules for rendering performance, security, accessibility, state management, and component testing. React is a JavaScript library for building user interfaces.

In plain words
What is it for?
Optimising React components, validating input, preventing cross-site scripting, managing state, supporting accessibility, and testing component behaviour.
Why use it?
They highlight common risks such as unnecessary re-rendering, unsafe input handling, inaccessible interfaces, and untested behaviour.

Cursor rule for Cursor

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/wangqiqi/cursor-ai-rules

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 291 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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-advanced 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 2d 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

⚛️ React 高级实践

本文档涵盖 React 高级开发主题。详细规范已拆分至独立规则。

⚠️ 执行原则

  • MUST 优化组件渲染性能
  • NEVER 在 render 中创建新函数
  • ALWAYS 使用适当的模式管理状态
  • DO NOT 忽略可访问性 (a11y)
  • MUST 实施安全最佳实践
  • ALWAYS 测试组件行为

  • 安全实践:见 @react-advanced-security(输入验证、DOMPurify、XSS 防护)
  • 最佳实践:见 @react-advanced-practices(文件组织、命名约定、HOC、Render Props、Compound Components)

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.

react-advanced is a cursor rule published in the GitHub repository wangqiqi/cursor-ai-rules (15 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 291 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
