mobx-dependency-injection

mobx-dependency-injection is a cursor rule for Cursor from holtwood/awesome-cursorrules-zh. It costs 0 tokens per session (474 once invoked), scanned A, original, MIT.

A pattern for giving React components access to MobX stores through React Context, a shared container for values across a component tree.

In plain words
What is it for?
Use it to provide shared MobX stores to React components and access them through a custom hook.
Why use it?
It avoids passing stores manually through every level of components, a problem known as prop drilling.

Cursor rule for Cursor

Written for Cursor: a Cursor rule (.mdc).

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { useStore } from '../stores';.

Good fit Use it to provide shared MobX stores to React components and access them through a custom hook.

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

mobx-dependency-injection 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 6d 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

  • 为 stores 实现适当的依赖注入
    • 使用 React Context 提供 store
      • 推荐使用 React Context API 来将 MobX store 注入到组件树中,避免手动通过 props 层层传递(prop drilling)。
      • 创建一个 StoreContext,并在应用程序的根组件中使用 Provider 提供 store 实例。
      • 示例:
        // stores/index.js
        import { createContext, useContext } from 'react';
        import { RootStore } from './RootStore';
        
        export const RootStoreInstance = new RootStore();
        export const StoreContext = createContext(RootStoreInstance);
        export const useStore = () => useContext(StoreContext);
        
        // App.js
        import React from 'react';
        import { StoreContext, RootStoreInstance } from './stores';
        
        function App() {
          return (
            <StoreContext.Provider value={RootStoreInstance}>
              {/* Your application components */}
            </StoreContext.Provider>
          );
        }
        
    • 自定义 Hook 简化使用
      • 创建一个自定义 Hook(如 useStore)来简化组件中对 store 的访问,提高代码可读性。
      • 示例:
        // components/MyComponent.js
        import React from 'react';
        import { observer } from 'mobx-react-lite';
        import { useStore } from '../stores';
        
        const MyComponent = observer(() => {
          const { userStore } = useStore();
        
          return (
            <div>
              <p>User Name: {userStore.name}</p>
              <button onClick={() => userStore.setName('New Name')}>Change Name</button>
            </div>
          );
        });
        
    • 测试友好:依赖注入使得在单元测试中替换或模拟 store 变得容易,提高了测试的独立性和效率。
    • 避免全局变量:避免将 store 实例作为全局变量直接导入,这会降低模块的独立性和可测试性。

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.
