Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00556 |
| Opus 5.5 | $0.00000 | $0.00222 |
| Sonnet 5.5 | $0.00000 | $0.00111 |
| Haiku 4.5 | $0.00000 | $0.00056 |
Grade A, and why
mobx-react-lite-usage 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 1mo 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
- 使用 MobX-react-lite 以在函数式组件中获得最佳性能：
observerHOC 或useObserverHook：- 对于函数式组件，推荐使用
mobx-react-lite提供的observer高阶组件（HOC）或useObserverHook 来包裹组件，使其能够响应 MobX 状态的变化。 observerHOC 示例：import React from 'react'; import { observer } from 'mobx-react-lite'; import { useStore } from '../stores'; const TodoList = observer(() => { const { todoStore } = useStore(); return ( <div> {todoStore.todos.map(todo => ( <div key={todo.id}>{todo.text}</div> ))} </div> ); }); export default TodoList;useObserverHook 示例（适用于需要更细粒度控制渲染的场景）：import React from 'react'; import { useObserver } from 'mobx-react-lite'; import { useStore } from '../stores'; const TodoItem = ({ todo }) => { return useObserver(() => ( <li> {todo.text} <button onClick={() => todo.toggleCompleted()}> {todo.completed ? 'Mark Incomplete' : 'Mark Complete'} </button> </li> )); }; export default TodoItem;
- 对于函数式组件，推荐使用
- 性能优化：
mobx-react-lite针对函数式组件进行了优化，只在组件实际观察到的数据发生变化时才重新渲染组件，从而最大限度地减少不必要的渲染。- 避免在
observer组件内部解构 MobX store 的可观察属性，这可能导致组件观察到整个 store 而不是特定属性，从而触发不必要的重新渲染。应在组件内部访问具体属性。
- 与 Hooks 结合使用：
mobx-react-lite与 React Hooks 完美结合，可以在observer组件内部自由使用useState,useEffect,useContext等 Hooks。
- 轻量级：
mobx-react-lite是一个轻量级的包，只提供了 MobX 与 React 函数式组件集成的核心功能，没有额外的负担。
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.

mobx-react-lite-usage is a cursor rule published in the GitHub repository holtwood/awesome-cursorrules-zh (239 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 556 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 2026-09-03.
