-# E2E BDD Test Coverage Assistant
-
-You are an E2E testing assistant. Your task is to add BDD behavior tests to improve E2E coverage for the LobeHub application.
-
-## Prerequisites
-
-Before starting, read the following documents:
-
-- `e2e/CLAUDE.md` - E2E testing guide and best practices
-- `e2e/docs/local-setup.md` - Local environment setup
-
-## Target Modules
-
-Based on the product architecture, prioritize modules by coverage status:
-
-| Module           | Sub-features                                        | Priority | Status |
-| ---------------- | --------------------------------------------------- | -------- | ------ |
-| **Agent**        | Builder, Conversation, Task                         | P0       | 🚧     |
-| **Agent Group**  | Builder, Group Chat                                 | P0       | ⏳      |
-| **Page (Docs)**  | Sidebar CRUD ✅, Title/Emoji ✅, Rich Text ✅, Copilot | P0       | 🚧     |
-| **Knowledge**    | Create, Upload, RAG Conversation                    | P1       | ⏳      |
-| **Memory**       | View, Edit, Associate                               | P2       | ⏳      |
-| **Home Sidebar** | Agent Mgmt, Group Mgmt                              | P1       | ✅      |
-| **Community**    | Browse, Interactions, Detail Pages                  | P1       | ✅      |
-| **Settings**     | User Settings, Model Provider                       | P2       | ⏳      |
-
-## Workflow
-
-### 1. Analyze Current Coverage
-
-**Step 1.1**: List existing feature files
-
-```bash
-find e2e/src/features -name "*.feature" -type f
-```
-
-**Step 1.2**: Review the product modules in `src/app/[variants]/(main)/` to identify untested user journeys
-
-**Step 1.3**: Check `e2e/CLAUDE.md` for the coverage matrix and identify gaps
-
-### 2. Select a Module to Test
-
-**Selection Criteria**:
-
-- Choose ONE module that is NOT yet covered or has incomplete coverage
-- Prioritize by: P0 > P1 > P2
-- Focus on user journeys that represent core product value
-
-**Module granularity examples**:
-
-- Agent conversation flow
-- Knowledge base RAG workflow
-- Settings configuration flow
-- Page document CRUD operations
-
-### 3. Create Module Directory and README
-
-**Step 3.1**: Create dedicated feature directory
-
-```bash
-mkdir -p e2e/src/features/{module-name}
-```
-
-**Step 3.2**: Create README.md with feature inventory
-
-Create `e2e/src/features/{module-name}/README.md` with:
-
-- Module overview and routes
-- Feature inventory table (功能点、描述、优先级、状态、测试文件)
-- Test file structure
-- Execution commands
-- Known issues
-
-**Example structure** (see `e2e/src/features/page/README.md`):
-
-```markdown
-# {Module} 模块 E2E 测试覆盖
-
-## 模块概述
-**路由**: `/module`, `/module/[id]`
-
-## 功能清单与测试覆盖
-
-### 1. 功能分组名称
-
-| 功能点 | 描述 | 优先级 | 状态 | 测试文件 |
-| ------ | ---- | ------ | ---- | -------- |
-| 功能A  | xxx  | P0     | ✅   | `xxx.feature` |
-| 功能B  | xxx  | P1     | ⏳   |          |
-
-## 测试文件结构
-## 测试执行
-## 已知问题
-## 更新记录
-```
-
-### 4. Explore Module Features
-
-**Step 4.1**: Use Task tool to explore the module
-
-```
-Use the Task tool with subagent_type=Explore to thoroughly explore:
-- Route structure in src/app/[variants]/(main)/{module}/
-- Feature components in src/features/
-- Store actions in src/store/{module}/
-- All user interactions (buttons, menus, forms)
-```
-
-**Step 4.2**: Document all features in README.md
-
-Group features by user journey area (e.g., Sidebar, Editor Header, Editor Content, etc.)
-
-### 5. Design Test Scenarios
-
-**Step 5.1**: Create feature files by functional area
-
-Feature file location: `e2e/src/features/{module}/{area}.feature`
-
-**Naming conventions**:
-
-- `crud.feature` - Basic CRUD operations
-- `editor-meta.feature` - Editor metadata (title, icon)
-- `editor-content.feature` - Rich text editing
-- `copilot.feature` - AI copilot interactions
-
-**Feature file template**:
-
-```gherkin
-@journey @P0 @{module-tag}
-Feature: {Feature Name in Chinese}
-
-  作为用户，我希望能够 {user goal}，
-  以便 {business value}
-
-  Background:
-    Given 用户已登录系统
-
-  # ============================================
-  # 功能分组注释
-  # ============================================
-
-  @{MODULE-AREA-001}
-  Scenario: {Scenario description in Chinese}
-    Given {precondition}
-    When {user action}
-    Then {expected outcome}
-    And {additional verification}
-```
-
-**Tag conventions**:
-
-```gherkin
-@journey      # User journey test (experience baseline)
-@smoke        # Smoke test (quick validation)
-@regression   # Regression test
-@skip         # Skip this test (known issue)
-
-@P0           # Highest priority (CI must run)
-@P1           # High priority (Nightly)
-@P2           # Medium priority (Pre-release)
-
-@agent        # Agent module
-@agent-group  # Agent Group module
-@page         # Page/Docs module
-@knowledge    # Knowledge base module
-@memory       # Memory module
-@settings     # Settings module
-@home         # Home sidebar module
-```
-
-### 6. Implement Step Definitions
-
-**Step 6.1**: Create step definition file
-
-Location: `e2e/src/steps/{module}/{area}.steps.ts`
-
-**Step definition template**:
-
-```typescript
-/**
- * {Module} {Area} Steps
- *
- * Step definitions for {description}
- */
-import { Given, When, Then } from '@cucumber/cucumber';
-import { expect } from '@playwright/test';
-
-import { CustomWorld } from '../../support/world';
-
-// ============================================
-// Given Steps
-// ============================================
-
-Given('用户打开一个文稿编辑器', async function (this: CustomWorld) {
-  console.log('   📍 Step: 创建并打开一个文稿...');
-  // Implementation
-  console.log('   ✅ 已打开文稿编辑器');
-});
-
-// ============================================
-// When Steps
-// ============================================
-
-When('用户点击标题输入框', async function (this: CustomWorld) {
-  console.log('   📍 Step: 点击标题输入框...');
-  // Implementation
-  console.log('   ✅ 已点击标题输入框');
-});
-
-// ============================================
-// Then Steps
-// ============================================
-
-Then('文稿标题应该更新为 {string}', async function (this: CustomWorld, title: string) {
-  console.log(`   📍 Step: 验证标题为 "${title}"...`);
-  // Assertions
-  console.log(`   ✅ 标题已更新为 "${title}"`);
-});
-```
-
-**Step 6.2**: Add hooks if needed
-
-Update `e2e/src/steps/hooks.ts` for new tag prefixes:
-
-```typescript
-const testId = pickle.tags.find(
-  (tag) =>
-    tag.name.startsWith('@COMMUNITY-') ||
-    tag.name.startsWith('@AGENT-') ||
-    tag.name.startsWith('@HOME-') ||
-    tag.name.startsWith('@PAGE-') ||    // Add new prefix
-    tag.name.startsWith('@ROUTES-'),
-);
-```
-
-### 7. Setup Mocks (If Needed)
-
-For LLM-related tests, use the mock framework:
-
-```typescript
-import { llmMockManager, presetResponses } from '../../mocks/llm';
-
-// Setup mock before navigation
-llmMockManager.setResponse('user message', 'Expected AI response');
-await llmMockManager.setup(this.page);
-```
-
-### 8. Run and Verify Tests
-
-**Step 8.1**: Start local environment
-
-```bash
-# From project root
-bun e2e/scripts/setup.ts --start
-```
-
-**Step 8.2**: Run dry-run first to verify step definitions
-
-```bash
-cd e2e
-BASE_URL=http://localhost:3006 \
-  DATABASE_URL=postgresql://postgres:postgres@localhost:5433/postgres \
-  pnpm exec cucumber-js --config cucumber.config.js --tags "@{module-tag}" --dry-run
-```
-
-**Step 8.3**: Run the new tests
-
-```bash
-# Run specific test by tag
-HEADLESS=false BASE_URL=http://localhost:3006 \
-  DATABASE_URL=postgresql://postgres:postgres@localhost:5433/postgres \
-  pnpm exec cucumber-js --config cucumber.config.js --tags "@{TEST-ID}"
-
-# Run all module tests (excluding skipped)
-HEADLESS=true BASE_URL=http://localhost:3006 \
-  DATABASE_URL=postgresql://postgres:postgres@localhost:5433/postgres \
-  pnpm exec cucumber-js --config cucumber.config.js --tags "@{module-tag} and not @skip"
-```
-
-**Step 8.4**: Fix any failures
-
-- Check screenshots in `e2e/screenshots/`
-- Adjust selectors and waits as needed
-- For flaky tests, add `@skip` tag and document in README known issues
-- Ensure tests pass consistently
-
-### 9. Update Documentation
-
-**Step 9.1**: Update module README.md
-
-- Mark completed features with ✅
-- Update test statistics
-- Add any known issues
-
-**Step 9.2**: Update this prompt file
-
-- Update module status in Target Modules table
-- Add any new best practices learned
-
-### 10. Create Pull Request

-## Important Rules
-
-- **DO** write feature files in Chinese (贴近产品需求)
-- **DO** add appropriate tags (@journey, @P0/@P1/@P2, @module-name)
-- **DO** mock LLM responses for stability
-- **DO** add console logs in step definitions for debugging
-- **DO** handle element visibility issues (desktop/mobile dual components)
-- **DO** use `page.waitForTimeout()` for animation/transition waits
-- **DO** support both Chinese and English text (e.g., `/^(无标题|Untitled)$/`)
-- **DO** create unique test data with timestamps to avoid conflicts
-- **DO NOT** depend on actual LLM API calls
-- **DO NOT** create flaky tests (ensure stability before PR)
-- **DO NOT** modify production code unless adding data-testid attributes
-- **DO NOT** skip running tests locally before creating PR
-
-## Element Locator Best Practices
-
-### Rich Text Editor (contenteditable)
-
-```typescript
-// Correct way to input in contenteditable
-const editor = this.page.locator('[contenteditable="true"]').first();
-await editor.click();
-await this.page.waitForTimeout(500);
-await this.page.keyboard.type(message, { delay: 30 });
-```
-
-### Slash Commands
-
-```typescript
-// Type slash and wait for menu to appear
-await this.page.keyboard.type('/', { delay: 100 });
-await this.page.waitForTimeout(800); // Wait for slash menu
-
-// Type command shortcut
-await this.page.keyboard.type('h1', { delay: 80 });
-await this.page.keyboard.press('Enter');
-```
-
-### Handling i18n (Chinese/English)
-
-```typescript
-// Support both languages for default values
-const defaultTitleRegex = /^(无标题|Untitled)$/;
-const pageItem = this.page.getByText(defaultTitleRegex).first();
-
-// Or for buttons
-const button = this.page.getByRole('button', { name: /choose.*icon|选择图标/i });
-```
-
-### Creating Unique Test Data
-
-```typescript
-// Use timestamps to avoid conflicts between test runs
-const uniqueTitle = `E2E Page ${Date.now()}`;
-```
-
-### Handling Multiple Matches
-
-```typescript
-// Use .first() or .nth() for multiple matches
-const element = this.page.locator('[data-testid="item"]').first();
-
-// Or filter by visibility
-const items = await this.page.locator('[data-testid="item"]').all();
-for (const item of items) {
-  if (await item.isVisible()) {
-    await item.click();
-    break;
-  }
-}
-```
-
-### Adding data-testid
-
-If needed for reliable element selection, add `data-testid` to components:
-
-```tsx
-<Component data-testid="unique-identifier" />
-```
-
-## Common Test Patterns
-
-### Navigation Test
-
-```gherkin
-Scenario: 用户导航到目标页面
-  Given 用户已登录系统
-  When 用户点击侧边栏的 "{menu-item}"
-  Then 应该跳转到 "{expected-url}"
-  And 页面标题应包含 "{expected-title}"
-```
-
-### CRUD Test
-
-```gherkin
-Scenario: 创建新项目
-  Given 用户已登录系统
-  When 用户点击创建按钮
-  And 用户输入名称 "{name}"
-  And 用户点击保存
-  Then 应该看到新创建的项目 "{name}"
-
-Scenario: 编辑项目
-  Given 用户已创建项目 "{name}"
-  When 用户打开项目编辑
-  And 用户修改名称为 "{new-name}"
-  And 用户保存更改
-  Then 项目名称应更新为 "{new-name}"
-
-Scenario: 删除项目
-  Given 用户已创建项目 "{name}"
-  When 用户删除该项目
-  And 用户确认删除
-  Then 项目列表中不应包含 "{name}"
-```
-
-### Editor Title/Meta Test
-
-```gherkin
-Scenario: 编辑文稿标题
-  Given 用户打开一个文稿编辑器
-  When 用户点击标题输入框
-  And 用户输入标题 "我的测试文稿"
-  And 用户按下 Enter 键
-  Then 文稿标题应该更新为 "我的测试文稿"
-```
-
-### Rich Text Editor Test
-
-```gherkin
-Scenario: 通过斜杠命令插入一级标题
-  Given 用户打开一个文稿编辑器
-  When 用户点击编辑器内容区域
-  And 用户输入斜杠命令 "/h1"
-  And 用户按下 Enter 键
-  And 用户输入文本 "一级标题内容"
-  Then 编辑器应该包含一级标题
-```
-
-### LLM Interaction Test
-
-```gherkin
-Scenario: AI 对话基本流程
-  Given 用户已登录系统
-  And LLM Mock 已配置
-  When 用户发送消息 "{user-message}"
-  Then 应该收到 AI 回复 "{expected-response}"
-  And 消息应显示在对话历史中
-```
-
-## Debugging Tips
-
-1. **Use HEADLESS=false** to see browser actions
-2. **Check screenshots** in `e2e/screenshots/` on failure
-3. **Add console.log** in step definitions
-4. **Increase timeouts** for slow operations
-5. **Use `page.pause()`** for interactive debugging
-6. **Run dry-run first** to verify all step definitions exist
-7. **Use @skip tag** for known flaky tests, document in README
-

-# Vercel React Best Practices
-
-Comprehensive performance optimization guide for React and Next.js applications, maintained by Vercel. Contains 45 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.
-
-## When to Apply
-
-Reference these guidelines when:
-- Writing new React components or Next.js pages
-- Implementing data fetching (client or server-side)
-- Reviewing code for performance issues
-- Refactoring existing React/Next.js code
-- Optimizing bundle size or load times
-
-## Rule Categories by Priority
-
-| Priority | Category | Impact | Prefix |
-|----------|----------|--------|--------|
-| 1 | Eliminating Waterfalls | CRITICAL | `async-` |
-| 2 | Bundle Size Optimization | CRITICAL | `bundle-` |
-| 3 | Server-Side Performance | HIGH | `server-` |
-| 4 | Client-Side Data Fetching | MEDIUM-HIGH | `client-` |
-| 5 | Re-render Optimization | MEDIUM | `rerender-` |
-| 6 | Rendering Performance | MEDIUM | `rendering-` |
-| 7 | JavaScript Performance | LOW-MEDIUM | `js-` |
-| 8 | Advanced Patterns | LOW | `advanced-` |
-
-## Quick Reference
-
-### 1. Eliminating Waterfalls (CRITICAL)
-
-- `async-defer-await` - Move await into branches where actually used
-- `async-parallel` - Use Promise.all() for independent operations
-- `async-dependencies` - Use better-all for partial dependencies
-- `async-api-routes` - Start promises early, await late in API routes
-- `async-suspense-boundaries` - Use Suspense to stream content
-
-### 2. Bundle Size Optimization (CRITICAL)
-
-- `bundle-barrel-imports` - Import directly, avoid barrel files
-- `bundle-dynamic-imports` - Use next/dynamic for heavy components
-- `bundle-defer-third-party` - Load analytics/logging after hydration
-- `bundle-conditional` - Load modules only when feature is activated
-- `bundle-preload` - Preload on hover/focus for perceived speed
-
-### 3. Server-Side Performance (HIGH)

-## Store Event Handlers in Refs
-
-Store callbacks in refs when used in effects that shouldn't re-subscribe on callback changes.
-
-**Incorrect (re-subscribes on every render):**
-
-```tsx
-function useWindowEvent(event: string, handler: (e) => void) {
-  useEffect(() => {
-    window.addEventListener(event, handler)
-    return () => window.removeEventListener(event, handler)
-  }, [event, handler])
-}
-```
-
-**Correct (stable subscription):**
-
-```tsx
-function useWindowEvent(event: string, handler: (e) => void) {
-  const handlerRef = useRef(handler)
-  useEffect(() => {
-    handlerRef.current = handler
-  }, [handler])
-
-  useEffect(() => {
-    const listener = (e) => handlerRef.current(e)
-    window.addEventListener(event, listener)
-    return () => window.removeEventListener(event, listener)
-  }, [event])
-}
-```
-
-**Alternative: use `useEffectEvent` if you're on latest React:**
-
-```tsx
-import { useEffectEvent } from 'react'
-
-function useWindowEvent(event: string, handler: (e) => void) {
-  const onEvent = useEffectEvent(handler)
-
-  useEffect(() => {
-    window.addEventListener(event, onEvent)
-    return () => window.removeEventListener(event, onEvent)
-  }, [event])
-}
-```
-
-`useEffectEvent` provides a cleaner API for the same pattern: it creates a stable function reference that always calls the latest version of the handler.

-## Prevent Waterfall Chains in API Routes
-
-In API routes and Server Actions, start independent operations immediately, even if you don't await them yet.
-
-**Incorrect (config waits for auth, data waits for both):**
-
-```typescript
-export async function GET(request: Request) {
-  const session = await auth()
-  const config = await fetchConfig()
-  const data = await fetchData(session.user.id)
-  return Response.json({ data, config })
-}
-```
-
-**Correct (auth and config start immediately):**
-
-```typescript
-export async function GET(request: Request) {
-  const sessionPromise = auth()
-  const configPromise = fetchConfig()
-  const session = await sessionPromise
-  const [config, data] = await Promise.all([
-    configPromise,
-    fetchData(session.user.id)
-  ])
-  return Response.json({ data, config })
-}
-```
-
-For operations with more complex dependency chains, use `better-all` to automatically maximize parallelism (see Dependency-Based Parallelization).

-## Defer Await Until Needed
-
-Move `await` operations into the branches where they're actually used to avoid blocking code paths that don't need them.
-
-**Incorrect (blocks both branches):**
-
-```typescript
-async function handleRequest(userId: string, skipProcessing: boolean) {
-  const userData = await fetchUserData(userId)
-  
-  if (skipProcessing) {
-    // Returns immediately but still waited for userData
-    return { skipped: true }
-  }
-  
-  // Only this branch uses userData
-  return processUserData(userData)
-}
-```
-
-**Correct (only blocks when needed):**
-
-```typescript
-async function handleRequest(userId: string, skipProcessing: boolean) {
-  if (skipProcessing) {
-    // Returns immediately without waiting
-    return { skipped: true }
-  }
-  
-  // Fetch only when needed
-  const userData = await fetchUserData(userId)
-  return processUserData(userData)
-}
-```
-
-**Another example (early return optimization):**
-
-```typescript
-// Incorrect: always fetches permissions
-async function updateResource(resourceId: string, userId: string) {
-  const permissions = await fetchPermissions(userId)
-  const resource = await getResource(resourceId)
-  
-  if (!resource) {
-    return { error: 'Not found' }
-  }
-  
-  if (!permissions.canEdit) {
-    return { error: 'Forbidden' }
-  }
-  
-  return await updateResourceData(resource, permissions)
-}
-
-// Correct: fetches only when needed
-async function updateResource(resourceId: string, userId: string) {
-  const resource = await getResource(resourceId)
-  
-  if (!resource) {
-    return { error: 'Not found' }
-  }
-  
-  const permissions = await fetchPermissions(userId)
-  
-  if (!permissions.canEdit) {
-    return { error: 'Forbidden' }
-  }
-  
-  return await updateResourceData(resource, permissions)
-}
-```
-
-This optimization is especially valuable when the skipped branch is frequently taken, or when the deferred operation is expensive.

-## Strategic Suspense Boundaries
-
-Instead of awaiting data in async components before returning JSX, use Suspense boundaries to show the wrapper UI faster while data loads.
-
-**Incorrect (wrapper blocked by data fetching):**
-
-```tsx
-async function Page() {
-  const data = await fetchData() // Blocks entire page
-  
-  return (
-    <div>
-      <div>Sidebar</div>
-      <div>Header</div>
-      <div>
-        <DataDisplay data={data} />
-      </div>
-      <div>Footer</div>
-    </div>
-  )
-}
-```
-
-The entire layout waits for data even though only the middle section needs it.
-
-**Correct (wrapper shows immediately, data streams in):**
-
-```tsx
-function Page() {
-  return (
-    <div>
-      <div>Sidebar</div>
-      <div>Header</div>
-      <div>
-        <Suspense fallback={<Skeleton />}>
-          <DataDisplay />
-        </Suspense>
-      </div>
-      <div>Footer</div>
-    </div>
-  )
-}
-
-async function DataDisplay() {
-  const data = await fetchData() // Only blocks this component
-  return <div>{data.content}</div>
-}
-```
-
-Sidebar, Header, and Footer render immediately. Only DataDisplay waits for data.
-
-**Alternative (share promise across components):**
-
-```tsx
-function Page() {
-  // Start fetch immediately, but don't await
-  const dataPromise = fetchData()
-  
-  return (
-    <div>
-      <div>Sidebar</div>
-      <div>Header</div>
-      <Suspense fallback={<Skeleton />}>
-        <DataDisplay dataPromise={dataPromise} />
-        <DataSummary dataPromise={dataPromise} />
-      </Suspense>
-      <div>Footer</div>
-    </div>
-  )
-}
-
-function DataDisplay({ dataPromise }: { dataPromise: Promise<Data> }) {
-  const data = use(dataPromise) // Unwraps the promise
-  return <div>{data.content}</div>
-}
-
-function DataSummary({ dataPromise }: { dataPromise: Promise<Data> }) {
-  const data = use(dataPromise) // Reuses the same promise
-  return <div>{data.summary}</div>
-}
-```
-
-Both components share the same promise, so only one fetch occurs. Layout renders immediately while both components wait together.
-
-**When NOT to use this pattern:**
-
-- Critical data needed for layout decisions (affects positioning)
-- SEO-critical content above the fold
-- Small, fast queries where suspense overhead isn't worth it
-- When you want to avoid layout shift (loading → content jump)
-
-**Trade-off:** Faster initial paint vs potential layout shift. Choose based on your UX priorities.

----
-
-## Avoid Barrel File Imports
-
-Import directly from source files instead of barrel files to avoid loading thousands of unused modules. **Barrel files** are entry points that re-export multiple modules (e.g., `index.js` that does `export * from './module'`).
-
-Popular icon and component libraries can have **up to 10,000 re-exports** in their entry file. For many React packages, **it takes 200-800ms just to import them**, affecting both development speed and production cold starts.
-
-**Why tree-shaking doesn't help:** When a library is marked as external (not bundled), the bundler can't optimize it. If you bundle it to enable tree-shaking, builds become substantially slower analyzing the entire module graph.
-
-**Incorrect (imports entire library):**
-
-```tsx
-import { Check, X, Menu } from 'lucide-react'
-// Loads 1,583 modules, takes ~2.8s extra in dev
-// Runtime cost: 200-800ms on every cold start
-
-import { Button, TextField } from '@mui/material'
-// Loads 2,225 modules, takes ~4.2s extra in dev
-```
-
-**Correct (imports only what you need):**
-
-```tsx
-import Check from 'lucide-react/dist/esm/icons/check'
-import X from 'lucide-react/dist/esm/icons/x'
-import Menu from 'lucide-react/dist/esm/icons/menu'
-// Loads only 3 modules (~2KB vs ~1MB)
-
-import Button from '@mui/material/Button'
-import TextField from '@mui/material/TextField'
-// Loads only what you use
-```
-
-**Alternative (Next.js 13.5+):**
-
-```js
-// next.config.js - use optimizePackageImports
-module.exports = {
-  experimental: {
-    optimizePackageImports: ['lucide-react', '@mui/material']
-  }
-}
-
-// Then you can keep the ergonomic barrel imports:
-import { Check, X, Menu } from 'lucide-react'
-// Automatically transformed to direct imports at build time
-```
-
-Direct imports provide 15-70% faster dev boot, 28% faster builds, 40% faster cold starts, and significantly faster HMR.
-
-Libraries commonly affected: `lucide-react`, `@mui/material`, `@mui/icons-material`, `@tabler/icons-react`, `react-icons`, `@headlessui/react`, `@radix-ui/react-*`, `lodash`, `ramda`, `date-fns`, `rxjs`, `react-use`.

-
-## Batch DOM CSS Changes
-
-Avoid interleaving style writes with layout reads. When you read a layout property (like `offsetWidth`, `getBoundingClientRect()`, or `getComputedStyle()`) between style changes, the browser is forced to trigger a synchronous reflow.
-
-**Incorrect (interleaved reads and writes force reflows):**
-
-```typescript
-function updateElementStyles(element: HTMLElement) {
-  element.style.width = '100px'
-  const width = element.offsetWidth  // Forces reflow
-  element.style.height = '200px'
-  const height = element.offsetHeight  // Forces another reflow
-}
-```
-
-**Correct (batch writes, then read once):**
-
-```typescript
-function updateElementStyles(element: HTMLElement) {
-  // Batch all writes together
-  element.style.width = '100px'
-  element.style.height = '200px'
-  element.style.backgroundColor = 'blue'
-  element.style.border = '1px solid black'
-  
-  // Read after all writes are done (single reflow)
-  const { width, height } = element.getBoundingClientRect()
-}
-```
-
-**Better: use CSS classes**
-
-```css
-.highlighted-box {
-  width: 100px;
-  height: 200px;
-  background-color: blue;
-  border: 1px solid black;
-}
-```
-
-```typescript
-function updateElementStyles(element: HTMLElement) {
-  element.classList.add('highlighted-box')
-
-  const { width, height } = element.getBoundingClientRect()
-}
-```
-
-Prefer CSS classes over inline styles when possible. CSS files are cached by the browser, and classes provide better separation of concerns and are easier to maintain.

-## Early Length Check for Array Comparisons
-
-When comparing arrays with expensive operations (sorting, deep equality, serialization), check lengths first. If lengths differ, the arrays cannot be equal.
-
-In real-world applications, this optimization is especially valuable when the comparison runs in hot paths (event handlers, render loops).
-
-**Incorrect (always runs expensive comparison):**
-
-```typescript
-function hasChanges(current: string[], original: string[]) {
-  // Always sorts and joins, even when lengths differ
-  return current.sort().join() !== original.sort().join()
-}
-```
-
-Two O(n log n) sorts run even when `current.length` is 5 and `original.length` is 100. There is also overhead of joining the arrays and comparing the strings.
-
-**Correct (O(1) length check first):**
-
-```typescript
-function hasChanges(current: string[], original: string[]) {
-  // Early return if lengths differ
-  if (current.length !== original.length) {
-    return true
-  }
-  // Only sort when lengths match
-  const currentSorted = current.toSorted()
-  const originalSorted = original.toSorted()
-  for (let i = 0; i < currentSorted.length; i++) {
-    if (currentSorted[i] !== originalSorted[i]) {
-      return true
-    }
-  }
-  return false
-}
-```
-
-This new approach is more efficient because:
-- It avoids the overhead of sorting and joining the arrays when lengths differ
-- It avoids consuming memory for the joined strings (especially important for large arrays)
-- It avoids mutating the original arrays
-- It returns early when a difference is found

-## Use toSorted() Instead of sort() for Immutability
-
-`.sort()` mutates the array in place, which can cause bugs with React state and props. Use `.toSorted()` to create a new sorted array without mutation.
-
-**Incorrect (mutates original array):**
-
-```typescript
-function UserList({ users }: { users: User[] }) {
-  // Mutates the users prop array!
-  const sorted = useMemo(

-    [users]
-  )
-  return <div>{sorted.map(renderUser)}</div>
-}
-```
-
-**Why this matters in React:**
-
-1. Props/state mutations break React's immutability model - React expects props and state to be treated as read-only
-2. Causes stale closure bugs - Mutating arrays inside closures (callbacks, effects) can lead to unexpected behavior
-
-**Browser support (fallback for older browsers):**
-
-`.toSorted()` is available in all modern browsers (Chrome 110+, Safari 16+, Firefox 115+, Node.js 20+). For older environments, use spread operator:
-
-```typescript
-// Fallback for older browsers
-const sorted = [...items].sort((a, b) => a.value - b.value)

-## Animate SVG Wrapper Instead of SVG Element
-
-Many browsers don't have hardware acceleration for CSS3 animations on SVG elements. Wrap SVG in a `<div>` and animate the wrapper instead.
-
-**Incorrect (animating SVG directly - no hardware acceleration):**
-
-```tsx
-function LoadingSpinner() {
-  return (
-    <svg 
-      className="animate-spin"
-      width="24" 
-      height="24" 
-      viewBox="0 0 24 24"
-    >
-      <circle cx="12" cy="12" r="10" stroke="currentColor" />
-    </svg>
-  )
-}
-```
-
-**Correct (animating wrapper div - hardware accelerated):**
-
-```tsx
-function LoadingSpinner() {
-  return (
-    <div className="animate-spin">
-      <svg 
-        width="24" 
-        height="24" 
-        viewBox="0 0 24 24"
-      >
-        <circle cx="12" cy="12" r="10" stroke="currentColor" />
-      </svg>
-    </div>
-  )
-}
-```
-
-This applies to all CSS transforms and transitions (`transform`, `opacity`, `translate`, `scale`, `rotate`). The wrapper div allows browsers to use GPU acceleration for smoother animations.

-## Prevent Hydration Mismatch Without Flickering
-
-When rendering content that depends on client-side storage (localStorage, cookies), avoid both SSR breakage and post-hydration flickering by injecting a synchronous script that updates the DOM before React hydrates.
-
-**Incorrect (breaks SSR):**
-
-```tsx
-function ThemeWrapper({ children }: { children: ReactNode }) {
-  // localStorage is not available on server - throws error
-  const theme = localStorage.getItem('theme') || 'light'
-  
-  return (
-    <div className={theme}>
-      {children}
-    </div>
-  )
-}
-```
-
-Server-side rendering will fail because `localStorage` is undefined.
-
-**Incorrect (visual flickering):**
-
-```tsx
-function ThemeWrapper({ children }: { children: ReactNode }) {
-  const [theme, setTheme] = useState('light')
-  
-  useEffect(() => {
-    // Runs after hydration - causes visible flash
-    const stored = localStorage.getItem('theme')
-    if (stored) {
-      setTheme(stored)
-    }
-  }, [])
-  
-  return (
-    <div className={theme}>
-      {children}
-    </div>
-  )
-}
-```
-
-Component first renders with default value (`light`), then updates after hydration, causing a visible flash of incorrect content.
-
-**Correct (no flicker, no hydration mismatch):**
-
-```tsx
-function ThemeWrapper({ children }: { children: ReactNode }) {
-  return (
-    <>
-      <div id="theme-wrapper">
-        {children}
-      </div>
-      <script
-        dangerouslySetInnerHTML={{
-          __html: `
-            (function() {
-              try {
-                var theme = localStorage.getItem('theme') || 'light';
-                var el = document.getElementById('theme-wrapper');
-                if (el) el.className = theme;
-              } catch (e) {}
-            })();
-          `,
-        }}
-      />
-    </>
-  )
-}
-```
-
-The inline script executes synchronously before showing the element, ensuring the DOM already has the correct value. No flickering, no hydration mismatch.
-
-This pattern is especially useful for theme toggles, user preferences, authentication states, and any client-only data that should render immediately without flashing default values.

-
-## Use Functional setState Updates
-
-When updating state based on the current state value, use the functional update form of setState instead of directly referencing the state variable. This prevents stale closures, eliminates unnecessary dependencies, and creates stable callback references.
-
-**Incorrect (requires state as dependency):**
-
-```tsx
-function TodoList() {
-  const [items, setItems] = useState(initialItems)
-  
-  // Callback must depend on items, recreated on every items change
-  const addItems = useCallback((newItems: Item[]) => {
-    setItems([...items, ...newItems])
-  }, [items])  // ❌ items dependency causes recreations
-  
-  // Risk of stale closure if dependency is forgotten
-  const removeItem = useCallback((id: string) => {
-    setItems(items.filter(item => item.id !== id))
-  }, [])  // ❌ Missing items dependency - will use stale items!
-  
-  return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />
-}
-```
-
-The first callback is recreated every time `items` changes, which can cause child components to re-render unnecessarily. The second callback has a stale closure bug—it will always reference the initial `items` value.
-
-**Correct (stable callbacks, no stale closures):**
-
-```tsx
-function TodoList() {
-  const [items, setItems] = useState(initialItems)
-  
-  // Stable callback, never recreated
-  const addItems = useCallback((newItems: Item[]) => {
-    setItems(curr => [...curr, ...newItems])
-  }, [])  // ✅ No dependencies needed
-  
-  // Always uses latest state, no stale closure risk
-  const removeItem = useCallback((id: string) => {
-    setItems(curr => curr.filter(item => item.id !== id))
-  }, [])  // ✅ Safe and stable
-  
-  return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />
-}
-```
-
-**Benefits:**
-
-1. **Stable callback references** - Callbacks don't need to be recreated when state changes
-2. **No stale closures** - Always operates on the latest state value
-3. **Fewer dependencies** - Simplifies dependency arrays and reduces memory leaks
-4. **Prevents bugs** - Eliminates the most common source of React closure bugs
-
-**When to use functional updates:**
-
-- Any setState that depends on the current state value
-- Inside useCallback/useMemo when state is needed
-- Event handlers that reference state
-- Async operations that update state
-
-**When direct updates are fine:**
-
-- Setting state to a static value: `setCount(0)`
-- Setting state from props/arguments only: `setName(newName)`
-- State doesn't depend on previous value
-
-**Note:** If your project has [React Compiler](https://react.dev/learn/react-compiler) enabled, the compiler can automatically optimize some cases, but functional updates are still recommended for correctness and to prevent stale closure bugs.

-## Cross-Request LRU Caching
-
-`React.cache()` only works within one request. For data shared across sequential requests (user clicks button A then button B), use an LRU cache.
-
-**Implementation:**
-
-```typescript
-import { LRUCache } from 'lru-cache'
-
-const cache = new LRUCache<string, any>({
-  max: 1000,
-  ttl: 5 * 60 * 1000  // 5 minutes
-})
-
-export async function getUser(id: string) {
-  const cached = cache.get(id)
-  if (cached) return cached
-
-  const user = await db.user.findUnique({ where: { id } })
-  cache.set(id, user)
-  return user
-}
-
-// Request 1: DB query, result cached
-// Request 2: cache hit, no DB query
-```
-
-Use when sequential user actions hit multiple endpoints needing the same data within seconds.
-
-**With Vercel's [Fluid Compute](https://vercel.com/docs/fluid-compute):** LRU caching is especially effective because multiple concurrent requests can share the same function instance and cache. This means the cache persists across requests without needing external storage like Redis.
-
-**In traditional serverless:** Each invocation runs in isolation, so consider Redis for cross-process caching.

-`React.cache()` uses shallow equality (`Object.is`) to determine cache hits. Inline objects create new references each call, preventing cache hits.
-
-**Incorrect (always cache miss):**
-
-```typescript
-const getUser = cache(async (params: { uid: number }) => {
-  return await db.user.findUnique({ where: { id: params.uid } })
-})
-
-// Each call creates new object, never hits cache
-getUser({ uid: 1 })
-getUser({ uid: 1 })  // Cache miss, runs query again
-```
-
-**Correct (cache hit):**
-
-```typescript
-const getUser = cache(async (uid: number) => {
-  return await db.user.findUnique({ where: { id: uid } })
-})
-
-// Primitive args use value equality
-getUser(1)
-getUser(1)  // Cache hit, returns cached result
-```
-
-If you must pass objects, pass the same reference:
-
-```typescript
-const params = { uid: 1 }
-getUser(params)  // Query runs
-getUser(params)  // Cache hit (same reference)
-```
-
-**Next.js-Specific Note:**
-
-In Next.js, the `fetch` API is automatically extended with request memoization. Requests with the same URL and options are automatically deduplicated within a single request, so you don't need `React.cache()` for `fetch` calls. However, `React.cache()` is still essential for other async tasks:
-
-- Database queries (Prisma, Drizzle, etc.)
-- Heavy computations
-- Authentication checks
-- File system operations
-- Any non-fetch async work
-
-Use `React.cache()` to deduplicate these operations across your component tree.

-## Minimize Serialization at RSC Boundaries

-The React Server/Client boundary serializes all object properties into strings and embeds them in the HTML response and subsequent RSC requests. This serialized data directly impacts page weight and load time, so **size matters a lot**. Only pass fields that the client actually uses.

-# Linear Issue Management
-
-When working with Linear issues:
-
-1. **Retrieve issue details** before starting work using `mcp__linear-server__get_issue`
-2. **Check for sub-issues**: If the issue has sub-issues, retrieve and review ALL sub-issues using `mcp__linear-server__list_issues` with `parentId` filter before starting work
-3. **Update issue status** when completing tasks using `mcp__linear-server__update_issue`
-4. **MUST add completion comment** using `mcp__linear-server__create_comment`
-
-## Creating Issues
-
-When creating new Linear issues using `mcp__linear-server__create_issue`, **MUST add the `claude code` label** to indicate the issue was created by Claude Code.
-
-## Completion Comment (REQUIRED)
-
-**Every time you complete an issue, you MUST add a comment summarizing the work done.** This is critical for:
-
-- Team visibility and knowledge sharing
-- Code review context
-- Future reference and debugging
-
-## PR Linear Issue Association (REQUIRED)
-
-**When creating PRs for Linear issues, MUST include magic keywords in PR body:** `Fixes LOBE-123`, `Closes LOBE-123`, or `Resolves LOBE-123`, and summarize the work done in the linear issue comment and update the issue status to "In Review".
-
-## IMPORTANT: Per-Issue Completion Rule
-
-**When working on multiple issues (e.g., parent issue with sub-issues), you MUST update status and add comment for EACH issue IMMEDIATELY after completing it.** Do NOT wait until all issues are done to update them in batch.
-
-**Workflow for EACH individual issue:**
-
-1. Complete the implementation for this specific issue
-2. Run type check: `bun run type-check`
-3. Run related tests if applicable
-4. Create PR if needed
-5. **IMMEDIATELY** update issue status to **"In Review"** (NOT "Done"): `mcp__linear-server__update_issue`
-6. **IMMEDIATELY** add completion comment: `mcp__linear-server__create_comment`
-7. Only then move on to the next issue
-
-**Note:** Issue status should be set to **"In Review"** when PR is created. The status will be updated to **"Done"** only after the PR is merged (usually handled by Linear-GitHub integration or manually).
-
-**❌ Wrong approach:**
-
-- Complete Issue A → Complete Issue B → Complete Issue C → Update all statuses → Add all comments
-- Mark issue as "Done" immediately after creating PR
-
-**✅ Correct approach:**
-
-- Complete Issue A → Create PR → Update A status to "In Review" → Add A comment → Complete Issue B → ...

-- **Collaborate（协作）**：多助理协作；群组对齐信息与产出；共享上下文（可控、可管理）。

 2. **分层表达（单一版本兼容两类用户）**：
-   - 主句：人人可懂、可执行
-   - 必要时补充一句副说明：更精确/更专业/更边界（可放副标题、帮助提示、折叠区）
-   - 不输出“Pro/Lite 两套文案”，而是“一句主文案 + 可选补充”

 3. **术语克制但准确**：能说“连接/运行/上下文”就不要堆砌术语；必须出现专业词时给一句白话解释。
 4. **一致性**：同一动作按钮尽量固定动词（创建/连接/运行/暂停/重试/查看详情/清除记忆等）。
 5. **可行动**：每条提示都要让用户知道下一步；按钮避免“确定/取消”泛化，改成更具体的动作。

-
 目标：在 AI 时代的价值焦虑与创作失格感中，给用户“被理解 + 有掌控 + 能继续”的体验，但不写长抒情。
 
 #### 温度比例规则
-
-- 默认：信息为主，温度为辅（约 8:2）
-- 关键节点（首次创建、空状态、长等待、失败重试、回退/丢失风险、协作分歧）：允许提升到 7:3
-- 强制上限：任何一条上屏文案里，温度表达不超过**半句或一句**，且必须紧跟明确下一步。

++ 强制上限：任何一条上屏文案里，温度表达不超过**半句或一句**，且必须紧跟明确下一步。
 
 #### 表达顺序（必须遵守）
-
 1. 先承接处境（不评判）：如“没关系/先这样也可以/卡住很正常”
 2. 再给掌控感（人在回路）：可暂停/可回放/可编辑/可撤销/可清除记忆/可查看上下文
 3. 最后给下一步（按钮/路径明确）
 
 #### 避免
-
-- 鸡汤式说教（如“别焦虑”“要相信未来”）
-- 宏大叙事与文学排比
-- 过度拟人（不承诺助理“理解你/有情绪/永远记得你”）

++ 助理很强，但它替代不了你的经历、选择与判断；LobeHub 帮你把时间还给重要的部分。
 
 ##### A. 情绪承接（先人后事）
-
-- 允许承认：焦虑、空白、无从下手、被追赶感、被替代感、创作枯竭、意义感动摇
-- 但不下结论、不说教：不输出“你要乐观/别焦虑”，改成“这种感觉很常见/你不是一个人”

++ 但不下结论、不说教：不输出“你要乐观/别焦虑”，改成“这种感觉很常见/你不是一个人”
 
 ##### B. 主体性回归（把人放回驾驶位）
-
-- 关键句式：**“决定权在你”**、**“你可以选择交给助理的部分”**、**“把你的想法变成可运行的流程”**
-- 强调可控：可编辑、可回放、可暂停、可撤销、可清除记忆、可查看上下文

 ##### C. 经历与关系（把价值从结果挪回过程）

     2. **再给掌控感**：强调“你可控/可选择/可回放/可撤销”
     3. **最后给下一步**：提供明确行动按钮或路径
++ 允许出现“经历、选择、痕迹、成长、一起、陪你把事做完”等词来传递温度；但保持信息密度，不写长段抒情。
++ 严肃场景（权限/安全/付费/数据丢失风险）仍以清晰与准确为先，温度通过“尊重与解释”体现，而不是煽情。

-## Test Fixing Principles
+## 测试修复原则
 
-### Core Principles
+### 核心原则
 
-1. **Gather Sufficient Context**
-   Before fixing tests, ensure you:
-   - Fully understand the test's intent and implementation
-   - Strongly recommended: review the current git diff and PR diff
+1. **收集足够的上下文**  
+   在修复测试之前，务必做到：
+   - 完整理解测试的意图和实现
+   - 强烈建议阅读当前的 git diff 和 PR diff
 
-2. **Prioritize Test Fixes**
-   If the test itself is incorrect, fix the test first rather than the implementation code.
+2. **测试优先修复**  
+   如果是测试本身写错了，应优先修改测试，而不是实现代码。
 
-3. **Focus on a Single Issue**
-   Only fix the specified test; don't add extra tests along the way.
+3. **专注单一问题**  
+   只修复指定的测试，不要顺带添加额外测试。
 
-4. **Don't Act Unilaterally**
-   When discovering other issues, don't modify them directly—raise and discuss first.
+4. **不自作主张**  
+   发现其他问题时，不要直接修改，需先提出并讨论。
 
-### Testing Collaboration Best Practices
+### 测试协作最佳实践
 
-Important collaboration principles based on real development experience:
+基于实际开发经验总结的重要协作原则：
 
-#### 1. Failure Handling Strategy
+#### 1. 失败处理策略
 
-**Core Principle**: Avoid blind retries; quickly identify problems and seek help.
+**核心原则**: 避免盲目重试，快速识别问题并寻求帮助。
 
-- **Failure Threshold**: After 1-2 consecutive failed fix attempts, stop immediately
-- **Problem Summary**: Analyze failure reasons and document attempted solutions with their failure causes
-- **Seek Help**: Approach the team with a clear problem summary and attempt history
-- **Avoid the Trap**: Don't fall into the loop of repeatedly trying the same or similar approaches
+- **失败阈值**: 当连续尝试修复测试 1-2 次都失败后，应立即停止继续尝试
+- **问题总结**: 分析失败原因，整理已尝试的解决方案及其失败原因
+- **寻求帮助**: 带着清晰的问题摘要和尝试记录向团队寻求帮助
+- **避免陷阱**: 不要陷入"不断尝试相同或类似方法"的循环
 
 ```typescript
-// ❌ Wrong approach: Keep blindly trying after consecutive failures
-// 3rd, 4th attempts still using similar methods to fix the same problem
+//  错误做法：连续失败后继续盲目尝试
+// 第3次、第4次仍在用相似的方法修复同一个问题
 
-// ✅ Correct approach: Summarize after 1-2 failures
+//  正确做法：失败1-2次后总结问题
 /*
-Problem Summary:
-1. Attempted method: Modified mock data structure
-2. Failure reason: Still getting type mismatch error
-3. Specific error: Expected 'UserData' but received 'UserProfile'
-4. Help needed: Unsure about the latest UserData interface definition
+问题总结：
+1. 尝试过的方法：修改 mock 数据结构
+2. 失败原因：仍然提示类型不匹配
+3. 具体错误：Expected 'UserData' but received 'UserProfile'
+4. 需要帮助：不确定最新的 UserData 接口定义
 */
 ```
 
-#### 2. Test Case Naming Conventions
+#### 2. 测试用例命名规范
 
-**Core Principle**: Tests should focus on "behavior," not "implementation details."
+**核心原则**: 测试应该关注"行为"，而不是"实现细节"。
 
-- **Describe Business Scenarios**: `describe` and `it` titles should describe specific business scenarios and expected behaviors
-- **Avoid Implementation Binding**: Don't mention specific line numbers, coverage goals, or implementation details in test names
-- **Maintain Stability**: Test names should remain meaningful after code refactoring
+- **描述业务场景**: `describe` 和 `it` 的标题应该描述具体的业务场景和预期行为
+- **避免实现绑定**: 不要在测试名称中提及具体的代码行号、覆盖率目标或实现细节
+- **保持稳定性**: 测试名称应该在代码重构后仍然有意义
 
 ```typescript
-// ❌ Poor test naming
+//  错误的测试命名
 describe('User component coverage', () => {
   it('covers line 45-50 in getUserData', () => {
-    // Test written just to cover lines 45-50
+    // 为了覆盖第45-50行而写的测试
   });
 
   it('tests the else branch', () => {
-    // Exists only to test a specific branch
+    // 仅为了测试某个分支而存在
   });
 });
 
-// ✅ Good test naming
+//  正确的测试命名
 describe('<UserAvatar />', () => {
   it('should render fallback icon when image url is not provided', () => {
-    // Tests a specific business scenario, naturally covering relevant code branches
+    // 测试具体的业务场景，自然会覆盖相关代码分支
   });
 
   it('should display user initials when avatar image fails to load', () => {
-    // Describes user behavior and expected outcome
+    // 描述用户行为和预期结果
   });
 });
 ```
 
-**The Right Approach to Improving Coverage**:
+**覆盖率提升的正确思路**:
 
-- Naturally improve coverage by designing various business scenarios (happy paths, edge cases, error handling)
-- Don't write tests just to hit coverage numbers, and never comment "to cover line xxx" in tests
+- 通过设计各种业务场景（正常流程、边缘情况、错误处理）来自然提升覆盖率
+- 不要为了达到覆盖率数字而写测试，更不要在测试中注释"为了覆盖 xxx 行"
 
-#### 3. Test Organization Structure
+#### 3. 测试组织结构
 
-**Core Principle**: Maintain a clear test hierarchy; avoid redundant top-level test blocks.
+**核心原则**: 维护清晰的测试层次结构，避免冗余的顶级测试块。
 
-- **Reuse Existing Structure**: When adding new tests, first look for an appropriate place in existing `describe` blocks
-- **Logical Grouping**: Related test cases should be organized within the same `describe` block
-- **Avoid Fragmentation**: Don't create a new top-level `describe` block for a single test case
+- **复用现有结构**: 添加新测试时，优先在现有的 `describe` 块中寻找合适的位置
+- **逻辑分组**: 相关的测试用例应该组织在同一个 `describe` 块内
+- **避免碎片化**: 不要为了单个测试用例就创建新的顶级 `describe` 块
 
 ```typescript
-// ❌ Poor organization: Too many top-level blocks
+//  错误的组织方式：创建过多顶级块
 describe('<UserProfile />', () => {
   it('should render user name', () => {});
 });
 
 describe('UserProfile new prop test', () => {
-  // Unnecessary new block
+  // 不必要的新块
   it('should handle email display', () => {});
 });
 
 describe('UserProfile edge cases', () => {
-  // Unnecessary new block
+  // 不必要的新块
   it('should handle missing avatar', () => {});
 });
 
-// ✅ Good organization: Merge related tests
+//  正确的组织方式：合并相关测试
 describe('<UserProfile />', () => {
   it('should render user name', () => {});
 
@@ -204,78 +178,78 @@ describe('<UserProfile />', () => {
   it('should handle missing avatar', () => {});
 
   describe('when user data is incomplete', () => {

     it('should show placeholder for missing name', () => {});
     it('should hide email section when email is undefined', () => {});
   });
 });
 ```
 
-**Organization Decision Flow**:
+**组织决策流程**:
 
-1. Is there a logically related existing `describe` block? → If yes, add to it
-2. Are there multiple (3+) related test cases? → If yes, consider creating a new sub-`describe`
-3. Is it an independent, unrelated feature module? → Only then consider creating a new top-level `describe`
+1. 是否存在逻辑相关的现有 `describe` 块？ → 如果有，添加到其中
+2. 是否有多个（3个以上）相关的测试用例？ → 如果有，可以考虑创建新的子 `describe`
+3. 是否是独立的、无关联的功能模块？ → 如果是，才考虑创建新的顶级 `describe`
 
-### Test Fixing Workflow
+### 测试修复流程
 
-1. **Reproduce the Issue**: Locate and run the failing test; confirm it can be reproduced locally
-2. **Analyze the Cause**: Read test code, error logs, and Git history of related files
-3. **Form a Hypothesis**: Determine if the problem is in test logic, implementation code, or environment configuration
-4. **Fix and Verify**: Apply the fix based on your hypothesis; rerun the test to confirm it passes
-5. **Expand Verification**: Run all tests in the current file to ensure no new issues were introduced
-6. **Write a Summary**: Document the error cause and fix method
+1. **复现问题**: 定位并运行失败的测试，确认能在本地复现
+2. **分析原因**: 阅读测试代码、错误日志和相关文件的 Git 修改历史
+3. **建立假设**: 判断问题出在测试逻辑、实现代码还是环境配置
+4. **修复验证**: 根据假设进行修复，重新运行测试确认通过
+5. **扩大验证**: 运行当前文件内所有测试，确保没有引入新问题
+6. **撰写总结**: 说明错误原因和修复方法

-**Root Cause**: The mock data format in the test didn't match the actual API response format, causing assertion failures.
+**错误原因**: 测试中的 mock 数据格式与实际 API 返回格式不匹配，导致断言失败。
 
-**Fix**: Updated the mock data structure in the test file to match the latest API response format. Specifically modified the `mockUserData` object structure in `user.test.ts`.

+**核心原则**: 测试数据应默认追求真实性，只有在引入"高昂的测试成本"时才进行简化。
 
-#### What Are "High Testing Costs"?
+#### 什么是"高昂的测试成本"？
 
-"High cost" refers to introducing external dependencies in tests that make them slow, unstable, or complex:
+"高成本"指的是测试中引入了外部依赖，使测试变慢、不稳定或复杂：
 
-- **File I/O Operations**: Reading/writing disk files
-- **Network Requests**: HTTP calls, database connections
-- **System Calls**: Getting system time, environment variables, etc.
+- **文件 I/O 操作**：读写硬盘文件
+- **网络请求**：HTTP 调用、数据库连接
+- **系统调用**：获取系统时间、环境变量等
 
-#### Recommended Approach: Mock Dependencies, Keep Real Data
+#### 推荐做法：Mock 依赖，保留真实数据
 
 ```typescript
-// ✅ Good approach: Mock I/O operations but use real file content formats
+//  好的做法：Mock I/O 操作，但使用真实的文件内容格式
 describe('parseContentType', () => {
   beforeEach(() => {
-    // Mock file read operation (avoid real I/O)
+    // Mock 文件读取操作（避免真实 I/O）
     vi.spyOn(fs, 'readFileSync').mockImplementation((path) => {
-      // But return real file content formats
-      if (path.includes('.pdf')) return '%PDF-1.4\n%âãÏÓ'; // Real PDF header
-      if (path.includes('.png')) return '\x89PNG\r\n\x1a\n'; // Real PNG header

       return '';
     });

+    // 这种简化数据没有测试价值

 ```
 
-#### The Value of Real Identifiers
+#### 真实标识符的价值
 
 ```typescript
-// ✅ Use real identifiers
+// ✅ 使用真实标识符
 const result = parseModelString('openai', '+gpt-4,+gpt-3.5-turbo');
 
-// ❌ Use placeholders (lower value)
+// ❌ 使用占位符（价值较低）

   vi.spyOn(URL, 'createObjectURL').mockReturnValue('blob:mock-url');
   vi.spyOn(URL, 'revokeObjectURL').mockImplementation(() => {});
 });
 ```
 
-#### Environment Selection Priority
+**环境选择优先级**
 
-1. **@vitest-environment happy-dom** (Recommended) - Lightweight, fast, already installed in the project
-2. **@vitest-environment jsdom** - Full-featured, but requires additional jsdom package installation
-3. **No environment set** - Node.js environment, requires manually mocking all browser APIs
+1. **@vitest-environment happy-dom** (推荐) - 轻量、快速，项目已安装
+2. **@vitest-environment jsdom** - 功能完整，但需要额外安装jsdom包
+3. **不设置环境** - Node.js环境，需要手动mock所有浏览器API
 
-#### Mock Method Comparison
+**Mock方法对比**
 
 ```typescript
-// ❌ Old method: Directly manipulating global object (type issues)
+// ❌ 旧方法：直接操作global对象（类型问题）
 global.Image = mockImage;
 global.URL = { ...global.URL, createObjectURL: mockFn };
 
-// ✅ Modern method: Type-safe vi API
-vi.stubGlobal('Image', mockImage); // Completely replace global object
-vi.spyOn(URL, 'createObjectURL'); // Partial mock, preserve other functionality
+// ✅ 现代方法：类型安全的vi API
+vi.stubGlobal('Image', mockImage); // 完全替换全局对象
+vi.spyOn(URL, 'createObjectURL'); // 部分mock，保留其他功能
 ```
 
-### Test Coverage Principles: Code Branches Over Test Quantity
+### 测试覆盖率原则：代码分支优于用例数量
 
-**Core Principle**: Prioritize covering all code branches rather than writing many repetitive test cases.
+**核心原则**: 优先覆盖所有代码分支，而非编写大量重复用例
 
 ```typescript
-// ❌ Over-testing: 29 test cases all validating the same branch
+// ❌ 过度测试：29个测试用例都验证相同分支
 describe('getImageDimensions', () => {
   it('should reject .txt files');
   it('should reject .pdf files');
-  // ... 25 similar tests, all hitting the same validation branch
+  // ... 25个类似测试，都走相同的验证分支
 });
 
-// ✅ Lean testing: 4 core cases covering all branches
+// ✅ 精简测试：4个核心用例覆盖所有分支
 describe('getImageDimensions', () => {
-  it('should return dimensions for valid File object'); // Success path - File
-  it('should return dimensions for valid data URI'); // Success path - String
-  it('should return undefined for invalid inputs'); // Input validation branch
-  it('should return undefined when image fails to load'); // Error handling branch
+  it('should return dimensions for valid File object'); // 成功路径 - File
+  it('should return dimensions for valid data URI'); // 成功路径 - String
+  it('should return undefined for invalid inputs'); // 输入验证分支
+  it('should return undefined when image fails to load'); // 错误处理分支
 });
 ```
 
-#### Branch Coverage Strategy
+**分支覆盖策略**
 
-1. **Success Paths** - One test per input type is sufficient
-2. **Boundary Conditions** - Consolidate similar scenarios into a single test
-3. **Error Handling** - Test representative errors only
-4. **Business Logic** - Cover all if/else branches
+1. **成功路径** - 每种输入类型1个测试即可
+2. **边界条件** - 合并类似场景到单个测试
+3. **错误处理** - 测试代表性错误即可
+4. **业务逻辑** - 覆盖所有if/else分支
 
-#### Reasonable Test Counts
+**合理测试数量**
 
-- Simple utility functions: 2-5 tests
-- Complex business logic: 5-10 tests
-- Core security features: Add more as needed, but avoid duplicate paths
+- 简单工具函数：2-5个测试
+- 复杂业务逻辑：5-10个测试
+- 核心安全功能：适当增加，但避免重复路径
 
-### Error Handling Tests: Test "Behavior" Not "Text"
+### 错误处理测试：测试"行为"而非"文本"
 
-**Core Principle**: Tests should verify that program behavior is predictable when errors occur, not verify error message text that may change.
+**核心原则**: 测试应该验证程序在错误发生时的行为是可预测的，而不是验证易变的错误信息文本。
 
-#### Recommended Error Testing Approach
+#### 推荐的错误测试方式
 
 ```typescript
-// ✅ Test error types and properties
+// ✅ 测试错误类型和属性
 expect(() => validateUser({})).toThrow(ValidationError);
 expect(() => processPayment({})).toThrow(
   expect.objectContaining({
@@ -399,136 +375,136 @@ expect(() => processPayment({})).toThrow(
   }),

-// ❌ Avoid testing specific error text
-expect(() => processUser({})).toThrow('User data cannot be empty, please check input parameters');
+// ❌ 避免测试具体错误文本
+expect(() => processUser({})).toThrow('用户数据不能为空，请检查输入参数');
 ```
 
-### Troubleshooting: Beware of Module Pollution
+### 疑难解答：警惕模块污染
 
-**Warning Signs**: When your tests exhibit these "mysterious" behaviors, suspect module pollution first:
+**识别信号**: 当你的测试出现以下"灵异"现象时，优先怀疑模块污染：
 
-- A test passes when run alone but fails when run with other tests
-- Test execution order affects results
-- Mock setup appears correct but actually uses an old mock version
+- 单独运行某个测试通过，但和其他测试一起运行就失败
+- 测试的执行顺序影响结果
+- Mock 设置看起来正确，但实际使用的是旧的 Mock 版本
 
-#### Typical Scenario: Dynamic Mocking of the Same Module
+#### 典型场景：动态 Mock 同一模块
 
 ```typescript
-// ❌ Problem: Dynamic mocking of the same module
+// ❌ 问题：动态Mock同一模块
 it('dev mode', async () => {
   vi.doMock('./config', () => ({ isDev: true }));
-  const { getSettings } = await import('./service'); // May use cache
+  const { getSettings } = await import('./service'); // 可能使用缓存
 });
 
-// ✅ Solution: Clear module cache
+// ✅ 解决：清除模块缓存
 beforeEach(() => {
-  vi.resetModules(); // Ensure each test has a clean environment
+  vi.resetModules(); // 确保每个测试都是干净环境
 });
 ```
 
-**Remember**: `vi.resetModules()` is the ultimate weapon for resolving "mysterious" test failures.
+**记住**: `vi.resetModules()` 是解决测试"灵异"失败的终极武器。
 
-## Test File Organization
+## 测试文件组织
 
-### File Naming Convention
+### 文件命名约定
 
-`*.test.ts`, `*.test.tsx` (any location)
+`*.test.ts`, `*.test.tsx` (任意位置)
 
-### Test File Organization Style
+### 测试文件组织风格
 
-The project uses a **co-located test files** organization style:
+项目采用 **测试文件与源文件同目录** 的组织风格：
 
-- Test files are placed in the same directory as the corresponding source files
-- Naming format: `originalFileName.test.ts` or `originalFileName.test.tsx`
+- 测试文件放在对应源文件的同一目录下
+- 命名格式：`原文件名.test.ts` 或 `原文件名.test.tsx`
 
-Example:
+例如：
 
 ```plaintext
 src/components/Button/
-├── index.tsx           # Source file
-└── index.test.tsx      # Test file
+├── index.tsx           # 源文件
+└── index.test.tsx      # 测试文件
 ```
 
-- In some cases, tests are consolidated in a `__tests__` folder, e.g., `packages/database/src/models/__tests__`
-- Test helper files are placed in a fixtures folder
+- 也有少数情况会统一放到 `__tests__` 文件夹， 例如 `packages/database/src/models/__tests__`
+- 测试使用的辅助文件放到 fixtures 文件夹
 
-## Test Debugging Tips
+## 测试调试技巧
 
-### Test Debugging Steps
+### 测试调试步骤
 
-1. **Determine Test Environment**: Select the correct config file based on file path
-2. **Isolate the Problem**: Use the `-t` flag to run only the failing test case
-3. **Analyze the Error**: Carefully read error messages, stack traces, and recent file modification history
-4. **Add Debugging**: Add `console.log` statements in tests to understand execution flow
+1. **确定测试环境**: 根据文件路径选择正确的配置文件
+2. **隔离问题**: 使用 `-t` 参数只运行失败的测试用例
+3. **分析错误**: 仔细阅读错误信息、堆栈跟踪和最近的文件修改记录
+4. **添加调试**: 在测试中添加 `console.log` 了解执行流程
 
-### TypeScript Type Handling
+### TypeScript 类型处理
 
-In tests, you can relax TypeScript type checking to improve writing efficiency and readability:
+在测试中，为了提高编写效率和可读性，可以适当放宽 TypeScript 类型检测：
 
-#### Recommended Type Relaxation Strategies
+#### 推荐的类型放宽策略
 
 ```typescript
-// Use non-null assertion to access properties you're certain exist in tests
+//  使用非空断言访问测试中确定存在的属性
 const result = await someFunction();
 expect(result!.data).toBeDefined();
 expect(result!.status).toBe('success');
 
-// Use any type to simplify complex mock setups
+//  使用 any 类型简化复杂的 Mock 设置
 const mockStream = new ReadableStream() as any;
 mockStream.toReadableStream = () => mockStream;
 
-// Access private members
-await instance['getFromCache']('key'); // Bracket notation recommended
-await (instance as any).getFromCache('key'); // Avoid as any
+//  访问私有成员
+await instance['getFromCache']('key'); // 推荐中括号
+await (instance as any).getFromCache('key'); // 避免as any
 ```
 
-#### Applicable Scenarios
+#### 适用场景
 
-- **Mock Objects**: Use `as any` for test mock data to avoid complex type definitions
-- **Third-Party Libraries**: Use `any` appropriately when handling complex third-party library types
-- **Test Assertions**: Use `!` non-null assertion in test scenarios where you're certain the object exists
-- **Private Member Access**: Prefer bracket notation `instance['privateMethod']()` over `(instance as any).privateMethod()`
-- **Temporary Debugging**: When quickly writing tests, use `any` first to ensure functionality, then optionally optimize types later
+- **Mock 对象**: 对于测试用的 Mock 数据，使用 `as any` 避免复杂的类型定义
+- **第三方库**: 处理复杂的第三方库类型时，适当使用 `any` 提高效率
+- **测试断言**: 在确定对象存在的测试场景中，使用 `!` 非空断言
+- **私有成员访问**: 优先使用中括号 `instance['privateMethod']()` 而不是 `(instance as any).privateMethod()`
+- **临时调试**: 快速编写测试时，先用 `any` 保证功能，后续可选择性地优化类型
 
-#### Important Notes
+#### 注意事项
 
-- **Use Moderately**: Don't over-rely on `any`; core business logic types should remain strict
-- **Private Member Access Priority**: Bracket notation > `as any` casting for better type safety
-- **Documentation**: Add comments explaining the reason for complex `any` usage scenarios
-- **Test Coverage**: Ensure tests still effectively verify correctness even when using `any`
+- **适度使用**: 不要过度依赖 `any`，核心业务逻辑的类型仍应保持严格
+- **私有成员访问优先级**: 中括号访问 > `as any` 转换，保持更好的类型安全性
+- **文档说明**: 对于使用 `any` 的复杂场景，添加注释说明原因
+- **测试覆盖**: 确保即使使用了 `any`，测试仍能有效验证功能正确性
 
-### Checking Recent Modifications
+### 检查最近修改记录
 
-**Core Principle**: When tests suddenly fail, first check recent code changes.
+**核心原则**：测试突然失败时，优先检查最近的代码修改。
 
-#### Quick Check Methods
+#### 快速检查方法
 
 ```bash
-git status                  # View current modification status
-git diff HEAD -- '*.test.*' # Check test file changes
-git diff main...HEAD        # Compare with main branch
-gh pr diff                  # View all changes in the PR
+git status                  # 查看当前修改状态
+git diff HEAD -- '*.test.*' # 检查测试文件改动
+git diff main...HEAD        # 对比主分支差异
+gh pr diff                  # 查看PR中的所有改动
 ```
 
-#### Common Causes and Solutions
+#### 常见原因与解决
 
-- **Latest commit introduced a bug** → Check and fix the implementation code
-- **Branch code is outdated** → `git rebase main` to sync with main branch
+- **最新提交引入bug** → 检查并修复实现代码
+- **分支代码滞后** → `git rebase main` 同步主分支

+- [数据库 Model 测试指南](mdc:./db-model-test.mdc)
 
-## Key Takeaways
+## 核心要点
 
-- **Command Format**: Use `bunx vitest run --silent='passed-only'` with file filtering
-- **Fix Principles**: Seek help after 1-2 failures; focus test naming on behavior, not implementation details
-- **Debug Workflow**: Reproduce → Analyze → Hypothesize → Fix → Verify → Summarize
-- **File Organization**: Prefer adding tests to existing `describe` blocks; avoid creating redundant top-level blocks
-- **Data Strategy**: Default to authenticity; only simplify for high-cost scenarios (I/O, network, etc.)
-- **Error Testing**: Test error types and behavior; avoid depending on specific error message text
-- **Module Pollution**: When tests fail "mysteriously," suspect module pollution first; use `vi.resetModules()` to resolve
-- **Security Requirements**: Model tests must include permission checks and pass in both environments
+- **命令格式**: 使用 `bunx vitest run --silent='passed-only'` 并指定文件过滤
+- **修复原则**: 失败1-2次后寻求帮助，测试命名关注行为而非实现细节
+- **调试流程**: 复现 → 分析 → 假设 → 修复 → 验证 → 总结
+- **文件组织**: 优先在现有 `describe` 块中添加测试，避免创建冗余顶级块
+- **数据策略**: 默认追求真实性，只有高成本（I/O、网络等）时才简化
+- **错误测试**: 测试错误类型和行为，避免依赖具体的错误信息文本
+- **模块污染**: 测试"灵异"失败时，优先怀疑模块污染，使用 `vi.resetModules()` 解决
+- **安全要求**: Model 测试必须包含权限检查，并在双环境下验证通过

-## Store Event Handlers in Refs
-
-Store callbacks in refs when used in effects that shouldn't re-subscribe on callback changes.
-
-**Incorrect (re-subscribes on every render):**
-
-```tsx
-function useWindowEvent(event: string, handler: (e) => void) {
-  useEffect(() => {
-    window.addEventListener(event, handler)
-    return () => window.removeEventListener(event, handler)
-  }, [event, handler])
-}
-```
-
-**Correct (stable subscription):**
-
-```tsx
-function useWindowEvent(event: string, handler: (e) => void) {
-  const handlerRef = useRef(handler)
-  useEffect(() => {
-    handlerRef.current = handler
-  }, [handler])
-
-  useEffect(() => {
-    const listener = (e) => handlerRef.current(e)
-    window.addEventListener(event, listener)
-    return () => window.removeEventListener(event, listener)
-  }, [event])
-}
-```
-
-**Alternative: use `useEffectEvent` if you're on latest React:**
-
-```tsx
-import { useEffectEvent } from 'react'
-
-function useWindowEvent(event: string, handler: (e) => void) {
-  const onEvent = useEffectEvent(handler)
-
-  useEffect(() => {
-    window.addEventListener(event, onEvent)
-    return () => window.removeEventListener(event, onEvent)
-  }, [event])
-}
-```
-
-`useEffectEvent` provides a cleaner API for the same pattern: it creates a stable function reference that always calls the latest version of the handler.

-## Prevent Waterfall Chains in API Routes
-
-In API routes and Server Actions, start independent operations immediately, even if you don't await them yet.
-
-**Incorrect (config waits for auth, data waits for both):**
-
-```typescript
-export async function GET(request: Request) {
-  const session = await auth()
-  const config = await fetchConfig()
-  const data = await fetchData(session.user.id)
-  return Response.json({ data, config })
-}
-```
-
-**Correct (auth and config start immediately):**
-
-```typescript
-export async function GET(request: Request) {
-  const sessionPromise = auth()
-  const configPromise = fetchConfig()
-  const session = await sessionPromise
-  const [config, data] = await Promise.all([
-    configPromise,
-    fetchData(session.user.id)
-  ])
-  return Response.json({ data, config })
-}
-```
-
-For operations with more complex dependency chains, use `better-all` to automatically maximize parallelism (see Dependency-Based Parallelization).

-## Defer Await Until Needed
-
-Move `await` operations into the branches where they're actually used to avoid blocking code paths that don't need them.
-
-**Incorrect (blocks both branches):**
-
-```typescript
-async function handleRequest(userId: string, skipProcessing: boolean) {
-  const userData = await fetchUserData(userId)
-  
-  if (skipProcessing) {
-    // Returns immediately but still waited for userData
-    return { skipped: true }
-  }
-  
-  // Only this branch uses userData
-  return processUserData(userData)
-}
-```
-
-**Correct (only blocks when needed):**
-
-```typescript
-async function handleRequest(userId: string, skipProcessing: boolean) {
-  if (skipProcessing) {
-    // Returns immediately without waiting
-    return { skipped: true }
-  }
-  
-  // Fetch only when needed
-  const userData = await fetchUserData(userId)
-  return processUserData(userData)
-}
-```
-
-**Another example (early return optimization):**
-
-```typescript
-// Incorrect: always fetches permissions
-async function updateResource(resourceId: string, userId: string) {
-  const permissions = await fetchPermissions(userId)
-  const resource = await getResource(resourceId)
-  
-  if (!resource) {
-    return { error: 'Not found' }
-  }
-  
-  if (!permissions.canEdit) {
-    return { error: 'Forbidden' }
-  }
-  
-  return await updateResourceData(resource, permissions)
-}
-
-// Correct: fetches only when needed
-async function updateResource(resourceId: string, userId: string) {
-  const resource = await getResource(resourceId)
-  
-  if (!resource) {
-    return { error: 'Not found' }
-  }
-  
-  const permissions = await fetchPermissions(userId)
-  
-  if (!permissions.canEdit) {
-    return { error: 'Forbidden' }
-  }
-  
-  return await updateResourceData(resource, permissions)
-}
-```
-
-This optimization is especially valuable when the skipped branch is frequently taken, or when the deferred operation is expensive.

-
-## Strategic Suspense Boundaries
-
-Instead of awaiting data in async components before returning JSX, use Suspense boundaries to show the wrapper UI faster while data loads.
-
-**Incorrect (wrapper blocked by data fetching):**
-
-```tsx
-async function Page() {
-  const data = await fetchData() // Blocks entire page
-  
-  return (
-    <div>
-      <div>Sidebar</div>
-      <div>Header</div>
-      <div>
-        <DataDisplay data={data} />
-      </div>
-      <div>Footer</div>
-    </div>
-  )
-}
-```
-
-The entire layout waits for data even though only the middle section needs it.
-
-**Correct (wrapper shows immediately, data streams in):**
-
-```tsx
-function Page() {
-  return (
-    <div>
-      <div>Sidebar</div>
-      <div>Header</div>
-      <div>
-        <Suspense fallback={<Skeleton />}>
-          <DataDisplay />
-        </Suspense>
-      </div>
-      <div>Footer</div>
-    </div>
-  )
-}
-
-async function DataDisplay() {
-  const data = await fetchData() // Only blocks this component
-  return <div>{data.content}</div>
-}
-```
-
-Sidebar, Header, and Footer render immediately. Only DataDisplay waits for data.
-
-**Alternative (share promise across components):**
-
-```tsx
-function Page() {
-  // Start fetch immediately, but don't await
-  const dataPromise = fetchData()
-  
-  return (
-    <div>
-      <div>Sidebar</div>
-      <div>Header</div>
-      <Suspense fallback={<Skeleton />}>
-        <DataDisplay dataPromise={dataPromise} />
-        <DataSummary dataPromise={dataPromise} />
-      </Suspense>
-      <div>Footer</div>
-    </div>
-  )
-}
-
-function DataDisplay({ dataPromise }: { dataPromise: Promise<Data> }) {
-  const data = use(dataPromise) // Unwraps the promise
-  return <div>{data.content}</div>
-}
-
-function DataSummary({ dataPromise }: { dataPromise: Promise<Data> }) {
-  const data = use(dataPromise) // Reuses the same promise
-  return <div>{data.summary}</div>
-}
-```
-
-Both components share the same promise, so only one fetch occurs. Layout renders immediately while both components wait together.
-
-**When NOT to use this pattern:**
-
-- Critical data needed for layout decisions (affects positioning)
-- SEO-critical content above the fold
-- Small, fast queries where suspense overhead isn't worth it
-- When you want to avoid layout shift (loading → content jump)
-
-**Trade-off:** Faster initial paint vs potential layout shift. Choose based on your UX priorities.

----
-
-## Avoid Barrel File Imports
-
-Import directly from source files instead of barrel files to avoid loading thousands of unused modules. **Barrel files** are entry points that re-export multiple modules (e.g., `index.js` that does `export * from './module'`).
-
-Popular icon and component libraries can have **up to 10,000 re-exports** in their entry file. For many React packages, **it takes 200-800ms just to import them**, affecting both development speed and production cold starts.
-
-**Why tree-shaking doesn't help:** When a library is marked as external (not bundled), the bundler can't optimize it. If you bundle it to enable tree-shaking, builds become substantially slower analyzing the entire module graph.
-
-**Incorrect (imports entire library):**
-
-```tsx
-import { Check, X, Menu } from 'lucide-react'
-// Loads 1,583 modules, takes ~2.8s extra in dev
-// Runtime cost: 200-800ms on every cold start
-
-import { Button, TextField } from '@mui/material'
-// Loads 2,225 modules, takes ~4.2s extra in dev
-```
-
-**Correct (imports only what you need):**
-
-```tsx
-import Check from 'lucide-react/dist/esm/icons/check'
-import X from 'lucide-react/dist/esm/icons/x'
-import Menu from 'lucide-react/dist/esm/icons/menu'
-// Loads only 3 modules (~2KB vs ~1MB)
-
-import Button from '@mui/material/Button'
-import TextField from '@mui/material/TextField'
-// Loads only what you use
-```
-
-**Alternative (Next.js 13.5+):**
-
-```js
-// next.config.js - use optimizePackageImports
-module.exports = {
-  experimental: {
-    optimizePackageImports: ['lucide-react', '@mui/material']
-  }
-}
-
-// Then you can keep the ergonomic barrel imports:
-import { Check, X, Menu } from 'lucide-react'
-// Automatically transformed to direct imports at build time
-```
-
-Direct imports provide 15-70% faster dev boot, 28% faster builds, 40% faster cold starts, and significantly faster HMR.
-
-Libraries commonly affected: `lucide-react`, `@mui/material`, `@mui/icons-material`, `@tabler/icons-react`, `react-icons`, `@headlessui/react`, `@radix-ui/react-*`, `lodash`, `ramda`, `date-fns`, `rxjs`, `react-use`.

-## Batch DOM CSS Changes
-
-Avoid interleaving style writes with layout reads. When you read a layout property (like `offsetWidth`, `getBoundingClientRect()`, or `getComputedStyle()`) between style changes, the browser is forced to trigger a synchronous reflow.
-
-**Incorrect (interleaved reads and writes force reflows):**
-
-```typescript
-function updateElementStyles(element: HTMLElement) {
-  element.style.width = '100px'
-  const width = element.offsetWidth  // Forces reflow
-  element.style.height = '200px'
-  const height = element.offsetHeight  // Forces another reflow
-}
-```
-
-**Correct (batch writes, then read once):**
-
-```typescript
-function updateElementStyles(element: HTMLElement) {
-  // Batch all writes together
-  element.style.width = '100px'
-  element.style.height = '200px'
-  element.style.backgroundColor = 'blue'
-  element.style.border = '1px solid black'
-  
-  // Read after all writes are done (single reflow)
-  const { width, height } = element.getBoundingClientRect()
-}
-```
-
-**Better: use CSS classes**
-
-```css
-.highlighted-box {
-  width: 100px;
-  height: 200px;
-  background-color: blue;
-  border: 1px solid black;
-}
-```
-
-```typescript
-function updateElementStyles(element: HTMLElement) {
-  element.classList.add('highlighted-box')
-
-  const { width, height } = element.getBoundingClientRect()
-}
-```
-
-Prefer CSS classes over inline styles when possible. CSS files are cached by the browser, and classes provide better separation of concerns and are easier to maintain.

-## Cache Repeated Function Calls
-
-Use a module-level Map to cache function results when the same function is called repeatedly with the same inputs during render.
-
-**Incorrect (redundant computation):**
-
-```typescript
-function ProjectList({ projects }: { projects: Project[] }) {
-  return (
-    <div>
-      {projects.map(project => {
-        // slugify() called 100+ times for same project names
-        const slug = slugify(project.name)
-        
-        return <ProjectCard key={project.id} slug={slug} />
-      })}
-    </div>
-  )
-}
-```
-
-**Correct (cached results):**
-
-```typescript
-// Module-level cache
-const slugifyCache = new Map<string, string>()
-
-function cachedSlugify(text: string): string {
-  if (slugifyCache.has(text)) {
-    return slugifyCache.get(text)!
-  }
-  const result = slugify(text)
-  slugifyCache.set(text, result)
-  return result
-}
-
-function ProjectList({ projects }: { projects: Project[] }) {
-  return (
-    <div>
-      {projects.map(project => {
-        // Computed only once per unique project name
-        const slug = cachedSlugify(project.name)
-        
-        return <ProjectCard key={project.id} slug={slug} />
-      })}
-    </div>
-  )
-}
-```
-
-**Simpler pattern for single-value functions:**
-
-```typescript
-let isLoggedInCache: boolean | null = null
-
-function isLoggedIn(): boolean {
-  if (isLoggedInCache !== null) {
-    return isLoggedInCache
-  }
-  
-  isLoggedInCache = document.cookie.includes('auth=')
-  return isLoggedInCache
-}
-
-// Clear cache when auth changes
-function onAuthChange() {
-  isLoggedInCache = null
-}
-```
-
-Use a Map (not a hook) so it works everywhere: utilities, event handlers, not just React components.

-
-## Early Length Check for Array Comparisons
-
-When comparing arrays with expensive operations (sorting, deep equality, serialization), check lengths first. If lengths differ, the arrays cannot be equal.
-
-In real-world applications, this optimization is especially valuable when the comparison runs in hot paths (event handlers, render loops).
-
-**Incorrect (always runs expensive comparison):**
-
-```typescript
-function hasChanges(current: string[], original: string[]) {
-  // Always sorts and joins, even when lengths differ
-  return current.sort().join() !== original.sort().join()
-}
-```
-
-Two O(n log n) sorts run even when `current.length` is 5 and `original.length` is 100. There is also overhead of joining the arrays and comparing the strings.
-
-**Correct (O(1) length check first):**
-
-```typescript
-function hasChanges(current: string[], original: string[]) {
-  // Early return if lengths differ
-  if (current.length !== original.length) {
-    return true
-  }
-  // Only sort when lengths match
-  const currentSorted = current.toSorted()
-  const originalSorted = original.toSorted()
-  for (let i = 0; i < currentSorted.length; i++) {
-    if (currentSorted[i] !== originalSorted[i]) {
-      return true
-    }
-  }
-  return false
-}
-```
-
-This new approach is more efficient because:
-- It avoids the overhead of sorting and joining the arrays when lengths differ
-- It avoids consuming memory for the joined strings (especially important for large arrays)
-- It avoids mutating the original arrays
-- It returns early when a difference is found

-## Use Loop for Min/Max Instead of Sort
-
-Finding the smallest or largest element only requires a single pass through the array. Sorting is wasteful and slower.

-**Incorrect (O(n log n) - sort to find latest):**
-
-```typescript
-interface Project {
-  id: string
-  name: string

-  const sorted = [...projects].sort((a, b) => a.updatedAt - b.updatedAt)
-  return { oldest: sorted[0], newest: sorted[sorted.length - 1] }
-}
-```
-
-Still sorts unnecessarily when only min/max are needed.
-
-**Correct (O(n) - single loop):**

-  if (projects.length === 0) return null
-  
-  let latest = projects[0]
-  
-  for (let i = 1; i < projects.length; i++) {
-    if (projects[i].updatedAt > latest.updatedAt) {
-      latest = projects[i]

-  for (let i = 1; i < projects.length; i++) {

-    if (projects[i].updatedAt > newest.updatedAt) newest = projects[i]
-  }
-  
-  return { oldest, newest }
-}
-```
-
-Single pass through the array, no copying, no sorting.
-
-**Alternative (Math.min/Math.max for small arrays):**
-
-```typescript
-const numbers = [5, 2, 8, 1, 9]
-const min = Math.min(...numbers)
-const max = Math.max(...numbers)
-```
-
-This works for small arrays, but can be slower or just throw an error for very large arrays due to spread operator limitations. Maximal array length is approximately 124000 in Chrome 143 and 638000 in Safari 18; exact numbers may vary - see [the fiddle](https://jsfiddle.net/qw1jabsx/4/). Use the loop approach for reliability.
