+# 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
+
+- Branch name: `test/e2e-{module-name}`
+- Commit message format:
+  ```
+  ✅ test: add E2E tests for {module-name}
+  ```
+- PR title: `✅ test: add E2E tests for {module-name}`
+- PR body template:
+
+  ````markdown

+
+## 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)
+
+- `server-cache-react` - Use React.cache() for per-request deduplication
+- `server-cache-lru` - Use LRU cache for cross-request caching
+- `server-serialization` - Minimize data passed to client components
+- `server-parallel-fetching` - Restructure components to parallelize fetches
+- `server-after-nonblocking` - Use after() for non-blocking operations
+
+### 4. Client-Side Data Fetching (MEDIUM-HIGH)
+
+- `client-swr-dedup` - Use SWR for automatic request deduplication
+- `client-event-listeners` - Deduplicate global event listeners
+
+### 5. Re-render Optimization (MEDIUM)
+
+- `rerender-defer-reads` - Don't subscribe to state only used in callbacks
+- `rerender-memo` - Extract expensive work into memoized components
+- `rerender-dependencies` - Use primitive dependencies in effects
+- `rerender-derived-state` - Subscribe to derived booleans, not raw values
+- `rerender-functional-setstate` - Use functional setState for stable callbacks
+- `rerender-lazy-state-init` - Pass function to useState for expensive values
+- `rerender-transitions` - Use startTransition for non-urgent updates
+
+### 6. Rendering Performance (MEDIUM)
+
+- `rendering-animate-svg-wrapper` - Animate div wrapper, not SVG element
+- `rendering-content-visibility` - Use content-visibility for long lists
+- `rendering-hoist-jsx` - Extract static JSX outside components
+- `rendering-svg-precision` - Reduce SVG coordinate precision
+- `rendering-hydration-no-flicker` - Use inline script for client-only data
+- `rendering-activity` - Use Activity component for show/hide
+- `rendering-conditional-render` - Use ternary, not && for conditionals
+
+### 7. JavaScript Performance (LOW-MEDIUM)
+
+- `js-batch-dom-css` - Group CSS changes via classes or cssText
+- `js-index-maps` - Build Map for repeated lookups
+- `js-cache-property-access` - Cache object properties in loops
+- `js-cache-function-results` - Cache function results in module-level Map
+- `js-cache-storage` - Cache localStorage/sessionStorage reads
+- `js-combine-iterations` - Combine multiple filter/map into one loop
+- `js-length-check-first` - Check array length before expensive comparison
+- `js-early-exit` - Return early from functions
+- `js-hoist-regexp` - Hoist RegExp creation outside loops
+- `js-min-max-loop` - Use loop for min/max instead of sort
+- `js-set-map-lookups` - Use Set/Map for O(1) lookups
+- `js-tosorted-immutable` - Use toSorted() for immutability
+
+### 8. Advanced Patterns (LOW)
+
+- `advanced-event-handler-refs` - Store event handlers in refs
+- `advanced-use-latest` - useLatest for stable callback refs
+
+## How to Use
+
+Read individual rule files for detailed explanations and code examples:
+
+```
+rules/async-parallel.md
+rules/bundle-barrel-imports.md
+rules/_sections.md
+```
+
+Each rule file contains:
+- Brief explanation of why it matters

+
+## 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)

+```typescript

+  }
+  
+  // Fetch only when needed
+  const userData = await fetchUserData(userId)
+  return processUserData(userData)
+}
+```
+
+**Another example (early return optimization):**
+
+```typescript

+
+## 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.

+impact: CRITICAL

+tags: bundle, imports, tree-shaking, barrel-files, performance
+---
+
+## 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

+
+**Incorrect (redundant computation):**
+
+```typescript
+function ProjectList({ projects }: { projects: Project[] }) {
+  return (
+    <div>
+      {projects.map(project => {

+  )
+}

+
+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 (

+        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

+  return isLoggedInCache
+}
+
+// Clear cache when auth changes
+function onAuthChange() {
+  isLoggedInCache = null
+}
+```

+---
+
+## 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

+
+```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.

+## 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[] }) {

+    [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:

+  )
+}

+
+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.

+impactDescription: prevents stale closures and unnecessary callback recreations

+---
+
+## 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.

+## Use Lazy State Initialization
+
+Pass a function to `useState` for expensive initial values. Without the function form, the initializer runs on every render even though the value is only used once.
+
+**Incorrect (runs on every render):**
+
+```tsx
+function FilteredList({ items }: { items: Item[] }) {
+  // buildSearchIndex() runs on EVERY render, even after initialization
+  const [searchIndex, setSearchIndex] = useState(buildSearchIndex(items))
+  const [query, setQuery] = useState('')

+  // When query changes, buildSearchIndex runs again unnecessarily
+  return <SearchResults index={searchIndex} query={query} />
+}
+
+function UserProfile() {
+  // JSON.parse runs on every render
+  const [settings, setSettings] = useState(
+    JSON.parse(localStorage.getItem('settings') || '{}')
+  )
+  
+  return <SettingsForm settings={settings} onChange={setSettings} />
+}
+```
+
+**Correct (runs only once):**
+
+```tsx
+function FilteredList({ items }: { items: Item[] }) {
+  // buildSearchIndex() runs ONLY on initial render
+  const [searchIndex, setSearchIndex] = useState(() => buildSearchIndex(items))
+  const [query, setQuery] = useState('')

+  return <SearchResults index={searchIndex} query={query} />

+    return stored ? JSON.parse(stored) : {}
+  })
+  
+  return <SettingsForm settings={settings} onChange={setSettings} />
+}
+```
+
+Use lazy initialization when computing initial values from localStorage/sessionStorage, building data structures (indexes, maps), reading from the DOM, or performing heavy transformations.
+
+For simple primitives (`useState(0)`), direct references (`useState(props.value)`), or cheap literals (`useState({})`), the function form is unnecessary.

+
+## 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.

+---
+
+## Per-Request Deduplication with React.cache()
+
+Use `React.cache()` for server-side request deduplication. Authentication and database queries benefit most.
+
+**Usage:**
+
+```typescript
+import { cache } from 'react'
+
+export const getCurrentUser = cache(async () => {
+  const session = await auth()
+  if (!session?.user?.id) return null
+  return await db.user.findUnique({
+    where: { id: session.user.id }
+  })
+})
+```
+
+Within a single request, multiple calls to `getCurrentUser()` execute the query only once.
+
+**Avoid inline objects as arguments:**
+
+`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.

+# createStaticStyles 迁移指南
+
+## 📖 概述
+
+`createStaticStyles` 是 `antd-style` 提供的静态样式创建函数，相比 `createStyles`（hook 方案）具有零运行时开销的优势。样式在模块加载时计算一次，而不是每次组件渲染时计算。
+
+## 🎯 适用场景
+
+### ✅ 可以优化的场景
+
+1. **纯静态样式**：不依赖运行时动态值
+2. **使用标准 token**：所有 token 都在 `cssVar.json` 中有对应项
+3. **简单的条件逻辑**：可以通过静态样式拆分处理
+
+### ❌ 无法优化的场景
+
+1. **JS 计算函数**：`readableColor()`, `chroma()`, `mix()`, `calc()` 中使用 token 数值
+2. **复杂的动态 props**：需要运行时计算的复杂逻辑
+3. **动态 prefixCls**：需要运行时传入的类名前缀（但可以硬编码为 `'ant'`）
+
+## 🔄 基本转换步骤
+
+### 1. 样式文件转换
+
+**之前（createStyles）：**
+
+```typescript
+import { createStyles } from 'antd-style';
+
+export const useStyles = createStyles(({ css, token }) => {
+  return {
+    root: css`
+      color: ${token.colorText};
+      font-size: ${token.fontSize}px;
+    `,
+  };
+});
+```
+
+**之后（createStaticStyles）：**
+
+```typescript
+import { createStaticStyles } from 'antd-style';
+
+export const styles = createStaticStyles(({ css, cssVar }) => {
+  return {
+    root: css`
+      color: ${cssVar.colorText};
+      font-size: ${cssVar.fontSize};
+    `,
+  };
+});
+```
+
+### 2. 组件文件转换
+
+**之前：**
+
+```typescript
+import { useStyles } from './style';
+
+const Component = () => {
+  const { styles, cx } = useStyles();
+  return <div className={cx(styles.root, className)} />;
+};
+```
+
+**之后：**
+
+```typescript
+import { cx } from 'antd-style';
+import { styles } from './style';
+
+const Component = () => {
+  return <div className={cx(styles.root, className)} />;
+};
+```
+
+## 🛠️ 常见场景处理
+
+### 场景 1: Token 转换
+
+**规则：**
+
+- `token.xxx` → `cssVar.xxx`
+- 注意：`cssVar.fontSize` 已经包含 `px` 单位，不需要再加 `px`
+
+**示例：**
+
+```typescript
+// ❌ 错误
+font-size: ${cssVar.fontSize}px;  // cssVar.fontSize 已经是 "14px"
+
+// ✅ 正确
+font-size: ${cssVar.fontSize};     // 直接使用
+```
+
+**特殊情况 - calc ()：**
+
+```typescript
+// ❌ 错误
+calc(${token.fontSize}px * 2.5)
+
+// ✅ 正确
+calc(${cssVar.fontSize} * 2.5)    // cssVar.fontSize 已经包含单位
+```
+
+### 场景 2: 动态 Props → CSS 变量
+
+**适用：** 数值、字符串类型的 props
+
+**步骤：**
+
+1. 在样式文件中使用 CSS 变量（带默认值）
+2. 在组件中通过 `style` prop 设置 CSS 变量
+
+**示例：**
+
+**样式文件：**
+
+```typescript
+export const styles = createStaticStyles(({ css }) => {
+  return {
+    root: css`
+      width: var(--component-size, 24px);
+      height: var(--component-size, 24px);
+    `,
+  };
+});
+```
+
+**组件文件：**
+
+```typescript
+import { useMemo } from 'react';
+
+const Component = ({ size = 24, style, ...rest }) => {
+  const cssVariables = useMemo<Record<string, string>>(
+    () => ({
+      '--component-size': `${size}px`,
+    }),
+    [size],
+  );
+
+  return (
+    <div
+      className={styles.root}
+      style={{
+        ...cssVariables,
+        ...style,
+      }}
+      {...rest}
+    />
+  );
+};
+```
+
+**已优化示例：**
+
+- `Video`: `maxHeight`, `maxWidth`, `minHeight`, `minWidth`
+- `ScrollShadow`: `size`
+- `MaskShadow`: `size`
+- `ColorSwatches`: `size`
+- `Grid`: `rows`, `maxItemWidth`, `gap`
+- `Layout`: `headerHeight`
+- `Footer`: `contentMaxWidth`
+
+### 场景 3: 布尔值 Props → 静态样式拆分
+
+**适用：** 简单的布尔值 props（2-3 个）
+
+**步骤：**
+
+1. 创建所有可能的组合样式
+2. 运行时使用 `cx` 组合
+
+**示例：**
+
+**样式文件：**
+
+```typescript
+export const styles = createStaticStyles(({ css }) => {
+  return {
+    root: css`
+      /* base styles */
+    `,
+    root_closable_true: css`
+      /* closable styles */
+    `,
+    root_closable_false: css`
+      /* no closable styles */
+    `,
+    root_hasTitle_true: css`
+      /* has title styles */
+    `,
+    root_hasTitle_false: css`
+      /* no title styles */
+    `,
+  };
+});
+```
+
+**组件文件：**
+
+```typescript
+const Component = ({ closable, hasTitle }) => {
+  const className = cx(
+    styles.root,
+    styles[`root_closable_${!!closable}`],
+    styles[`root_hasTitle_${!!hasTitle}`],
+  );
+  return <div className={className} />;
+};
+```
+
+**已优化示例：**
+
+- `Alert`: `closable`, `hasTitle`, `showIcon` → 8 个组合（2×2×2）
+- `Image`: `alwaysShowActions` → 2 个样式
+- `StoryBook`: `noPadding` → 2 个样式
+
+### 场景 4: isDarkMode → 静态样式拆分
+
+**适用：** 依赖 `isDarkMode` 的条件样式
+
+**有两种处理方式：**
+
+#### 方式 A: 直接条件选择（简单场景）
+
+**步骤：**
+
+1. 创建 `Dark` 和 `Light` 两个静态样式
+2. 运行时根据 `theme.isDarkMode` 选择
+
+**示例：**
+
+**样式文件：**
+
+```typescript
+export const styles = createStaticStyles(({ css, cssVar }) => {
+  return {
+    rootDark: css`
+      background: ${cssVar.colorFillTertiary};
+      color: ${cssVar.colorTextLightSolid};
+    `,
+    rootLight: css`
+      background: ${cssVar.colorFillQuaternary};
+      color: ${cssVar.colorText};
+    `,
+  };
+});
+```
+
+**组件文件：**
+
+```typescript
+import { useThemeMode } from 'antd-style';
+
+const Component = () => {
+  const { isDarkMode } = useThemeMode();
+  return (
+    <div
+      className={cx(
+        isDarkMode ? styles.rootDark : styles.rootLight
+      )}
+    />
+  );
+};
+```
+
+#### 方式 B: 使用 cva 将 isDarkMode 作为 variant（推荐，适用于复杂场景）
+
+**步骤：**
+
+1. 创建 `Dark` 和 `Light` 两个静态样式
+2. 在 `cva` 中将 `isDarkMode` 作为 variant prop
+3. 运行时直接传入 `isDarkMode` 值
+
+**示例：**
+
+**样式文件：**
+
+```typescript
+import { createStaticStyles } from 'antd-style';
+import { cva } from 'class-variance-authority';
+
+export const styles = createStaticStyles(({ css, cssVar }) => {
+  return {
+    filledDark: css`
+      background: ${cssVar.colorFillTertiary};
+      color: ${cssVar.colorTextLightSolid};
+    `,
+    filledLight: css`
+      background: ${cssVar.colorFillQuaternary};
+      color: ${cssVar.colorText};
+    `,
+    outlined: css`
+      border: 1px solid ${cssVar.colorBorder};
+    `,
+    root: css`
+      /* base styles */
+    `,
+  };
+});
+
+export const variants = cva(styles.root, {
+  defaultVariants: {
+    isDarkMode: false,
+    variant: 'filled',
+  },
+  variants: {
+    isDarkMode: {
+      false: null,
+      true: null, // isDarkMode 本身不添加样式，通过 compoundVariants 组合
+    },
+    variant: {
+      filled: null, // variant 本身不添加样式，通过 compoundVariants 组合
+      outlined: styles.outlined,
+    },
+  },
+  compoundVariants: [
+    {
+      class: styles.filledDark,
+      isDarkMode: true,
+      variant: 'filled',
+    },
+    {
+      class: styles.filledLight,
+      isDarkMode: false,
+      variant: 'filled',
+    },
+  ],
+});
+```
+
+**组件文件：**
+
+```typescript
+import { useThemeMode } from 'antd-style';
+import { variants } from './style';
+
+const Component = ({ variant = 'filled' }) => {
+  const { isDarkMode } = useThemeMode();
+  return (
+    <div
+      className={variants({ isDarkMode, variant })}
+    />
+  );
+};
+```
+
+**优势：**
+
+- ✅ 不需要 `useMemo` 动态创建 variants
+- ✅ 更符合 `cva` 的设计理念
+- ✅ 代码更简洁，性能更好
+- ✅ 类型安全，IDE 自动补全
+
+**已优化示例：**
+
+- `TypewriterEffect`: `textDark` / `textLight`（方式 A）
+- `Collapse`: `filledDark` / `filledLight`（可优化为方式 B）
+- `Hotkey`: `inverseThemeDark` / `inverseThemeLight`（可优化为方式 B）
+- `GuideCard`: `filledDark` / `filledLight`（可优化为方式 B）
+- `GradientButton`: `buttonDark` / `buttonLight`（方式 A）
+
+### 场景 5: responsive → 静态 responsive
+
+**适用：** 使用响应式断点
+
+**步骤：**
+
+1. 导入静态 `responsive` from `antd-style`
+2. 使用 `responsive.sm` 替代 `responsive.mobile`
+3. 从 `createStyles` 参数中移除 `responsive`
+
+**示例：**
+
+**之前：**
+
+```typescript
+import { createStyles } from 'antd-style';
+
+export const useStyles = createStyles(({ css, responsive }) => ({
+  root: css`
+    ${responsive.mobile} {
+      padding: 12px;
+    }
+  `,
+}));
+```
+
+**之后：**
+
+```typescript
+import { createStaticStyles } from 'antd-style';
+import { responsive } from 'antd-style';
+
+export const styles = createStaticStyles(({ css }) => ({
+  root: css`
+    ${responsive.sm} {
+      padding: 12px;
+    }
+  `,
+}));
+```
+
+**注意：**
+
+- `responsive.mobile` → `responsive.sm`
+- 静态 `responsive` 提供：`xs`, `sm`, `md`, `lg`, `xl`, `xxl`
+
+**已优化示例：**
+
+- `Header`: `responsive.mobile` → `responsive.sm`
+- `FormModal`: `responsive.mobile` → `responsive.sm`
+- `Hero`: `responsive.mobile` → `responsive.sm`
+
+### 场景 6: stylish → lobeStaticStylish
+
+**适用：** 使用自定义 `stylish` 工具
+
+**步骤：**
+
+1. 导入 `lobeStaticStylish` from `@/styles`
+2. 替换 `stylish.xxx` → `lobeStaticStylish.xxx`
+
+**示例：**
+
+**之前：**
+
+```typescript
+import { createStyles } from 'antd-style';
+
+export const useStyles = createStyles(({ css, stylish }) => ({
+  root: css`
+    ${stylish.blur};
+    ${stylish.variantFilled};
+  `,
+}));
+```
+
+**之后：**
+
+```typescript
+import { createStaticStyles } from 'antd-style';
+
+import { lobeStaticStylish } from '@/styles';
+
+export const styles = createStaticStyles(({ css }) => ({
+  root: css`
+    ${lobeStaticStylish.blur};
+    ${lobeStaticStylish.variantFilled};
+  `,
+}));
+```
+
+**已优化示例：**
+
+- `Button`: `stylish.blur` → `lobeStaticStylish.blur`
+- `Hero`: `stylish.gradientAnimation` → `lobeStaticStylish.gradientAnimation`
+
+### 场景 7: prefixCls → 硬编码
+
+**适用：** 使用动态 `prefixCls` 参数
+
+**步骤：**
+
+1. 在文件顶部硬编码 `const prefixCls = 'ant'`
+2. 从 `createStyles` 参数中移除 `prefixCls`
+
+**示例：**
+
+**之前：**
+
+```typescript
+export const useStyles = createStyles(({ css }, prefixCls: string) => ({
+  root: css`
+    .${prefixCls}-button {
+      /* styles */
+    }
+  `,
+}));
+```
+
+**之后：**
+
+```typescript
+const prefixCls = 'ant';
+
+export const styles = createStaticStyles(({ css }) => ({
+  root: css`
+    .${prefixCls}-button {
+      /* styles */
+    }
+  `,
+}));
+```
+
+**已优化示例：**
+
+- `Alert`, `Collapse`, `FormModal`, `Image`, `Burger`, `DraggablePanel`, `DraggableSideNav`, `Toc`, `ColorSwatches`, `EmojiPicker`, `Form`, `awesome/Features`
+
+### 场景 8: readableColor () → Token 替换
+
+**适用：** 使用 `readableColor()` 计算对比色
+
+**规则：**
+
+- `readableColor(token.colorPrimary)` → `cssVar.colorTextLightSolid`（主色背景用白色文字）
+- `readableColor(token.colorTextQuaternary)` → `cssVar.colorText`（浅色背景用深色文字）
+
+**示例：**
+
+**之前：**
+
+```typescript
+import { readableColor } from 'polished';
+
+export const useStyles = createStyles(({ css, token }) => ({
+  checked: css`
+    background-color: ${token.colorPrimary};
+    color: ${readableColor(token.colorPrimary)};
+  `,
+}));
+```
+
+**之后：**
+
+```typescript
+export const styles = createStaticStyles(({ css, cssVar }) => ({
+  checked: css`
+    background-color: ${cssVar.colorPrimary};
+    color: ${cssVar.colorTextLightSolid};
+  `,
+}));
+```
+
+**已优化示例：**
+
+- `Checkbox`: `readableColor(token.colorPrimary)` → `cssVar.colorTextLightSolid`
+
+### 场景 9: rgba () → color-mix ()
+
+**适用：** 使用 `rgba()` 设置透明度
+
+**步骤：**
+
+1. 使用 CSS 原生的 `color-mix()` 函数
+2. 格式：`color-mix(in srgb, ${cssVar.xxx} alpha%, transparent)`
+
+**示例：**
+
+**之前：**
+
+```typescript
+import { rgba } from 'polished';
+
+export const useStyles = createStyles(({ css, token }) => ({
+  root: css`
+    background-color: ${rgba(token.colorBgLayout, 0.4)};
+  `,
+}));
+```
+
+**之后：**
+
+```typescript
+export const styles = createStaticStyles(({ css, cssVar }) => ({
+  root: css`
+    background-color: color-mix(in srgb, ${cssVar.colorBgLayout} 40%, transparent);
+  `,
+}));
+```
+
+**已优化示例：**
+
+- `Header`: `rgba(cssVar.colorBgLayout, 0.4)` → `color-mix(...)`
+- `FormModal`: `rgba(cssVar.colorBgContainer, 0)` → `color-mix(...)`
+
+### 场景 10: keyframes → css
+
+**适用：** 使用 `keyframes` 创建动画
+
+**步骤：**
+
+1. 在 `createStaticStyles` 外部定义 `keyframes`
+2. 在样式内部使用
+
+**示例：**
+
+**之前：**
+
+```typescript
+export const useStyles = createStyles(({ css, keyframes }) => {
+  const spin = keyframes`
+    from { transform: rotate(0deg); }
+    to { transform: rotate(360deg); }
+  `;
+  return {
+    icon: css`
+      animation: ${spin} 1s linear infinite;
+    `,
+  };
+});
+```
+
+**之后：**
+
+```typescript
+import { keyframes } from 'antd-style';
+
+const spin = keyframes`
+  from { transform: rotate(0deg); }
+  to { transform: rotate(360deg); }
+`;
+
+export const styles = createStaticStyles(({ css }) => ({
+  icon: css`
+    animation: ${spin} 1s linear infinite;
+  `,
+}));
+```
+
+**已优化示例：**
+
+- `Icon`: `keyframes` 动画
+- `Skeleton`: `keyframes` shimmer 动画
+
+## ⚠️ 反模式：避免使用 createVariants (isDarkMode)
+
+**不推荐的做法：**
+
+```typescript
+// ❌ 不推荐：在组件中动态创建 variants
+export const createVariants = (isDarkMode: boolean) =>
+  cva(styles.root, {
+    variants: {
+      variant: {
+        filled: isDarkMode ? styles.filledDark : styles.filledLight,
+      },
+    },
+  });
+
+// 组件中
+const variants = useMemo(() => createVariants(isDarkMode), [isDarkMode]);
+```
+
+**推荐的做法：**
+
+将 `isDarkMode` 作为 `cva` 的 variant prop（见场景 4 方式 B），这样：
+
+- ✅ 不需要 `useMemo` 动态创建
+- ✅ 更符合 `cva` 的设计理念
+- ✅ 代码更简洁，性能更好
+- ✅ 类型安全，IDE 自动补全
+
+```typescript
+// ✅ 推荐：将 isDarkMode 作为 variant prop
+export const variants = cva(styles.root, {
+  variants: {
+    isDarkMode: {
+      false: null,
+      true: null,
+    },
+    variant: {
+      filled: null,
+    },
+  },
+  compoundVariants: [
+    {
+      class: styles.filledDark,
+      isDarkMode: true,
+      variant: 'filled',
+    },
+    {
+      class: styles.filledLight,
+      isDarkMode: false,
+      variant: 'filled',
+    },
+  ],
+});
+
+// 组件中
+const { isDarkMode } = useThemeMode();
+const className = variants({ isDarkMode, variant: 'filled' });
+```
+
+## ⚠️ 无法优化的场景
+
+### 1. JS 计算函数
+
+**无法优化：**
+
+- `chroma()` - 颜色计算库
+- `readableColor()` - 需要运行时计算（但可以用 token 替代）
+- `mix()` - 颜色混合计算
+- `calc()` 中使用 token 数值进行复杂计算
+
+**示例：**
+
+```typescript
+// ❌ 无法优化
+const scale = chroma.bezier([token.colorText, backgroundColor]).scale().colors(6);
+```
+
+### 2. 复杂的动态 Props
+
+**无法优化：**
+
+- 需要复杂计算的 props
+- 对象 / 数组类型的 props
+- 函数类型的 props
+
+### 3. useTheme Hook
+
+**无法优化：**
+
+- 直接使用 `useTheme()` hook 获取运行时值
+- 例如：`awesome/Giscus/style.ts` 使用 `useTheme()` 获取主题值
+
+## 📋 迁移检查清单
+
+### 样式文件检查
+
+- [ ] `createStyles` → `createStaticStyles`
+- [ ] `token.xxx` → `cssVar.xxx`
+- [ ] 移除 `px` 后缀（`cssVar` 已包含单位）
+- [ ] `responsive.mobile` → `responsive.sm`（如果使用）
+- [ ] `stylish.xxx` → `lobeStaticStylish.xxx`（如果使用）
+- [ ] `rgba()` → `color-mix()`（如果使用）
+- [ ] `readableColor()` → token 替换（如果使用）
+- [ ] `prefixCls` 参数 → 硬编码 `const prefixCls = 'ant'`（如果使用）
+- [ ] `isDarkMode` → 静态样式拆分（如果使用）
+- [ ] 动态 props → CSS 变量（如果使用）
+
+### 组件文件检查
+
+- [ ] `useStyles()` → `import { styles } from './style'`
+- [ ] `import { cx } from 'antd-style'`（如果需要）
+- [ ] `import { useTheme } from 'antd-style'`（如果需要 `theme.isDarkMode`）
+- [ ] 动态 props → CSS 变量设置（如果使用）
+- [ ] `isDarkMode` 条件 → `theme.isDarkMode` 判断（如果使用）
+
+## 🎯 优化优先级
+
+### 高优先级（简单优化）
+
+1. ✅ 纯静态样式（无动态 props）
+2. ✅ `isDarkMode` 拆分
+3. ✅ `responsive.mobile` → `responsive.sm`
+4. ✅ `stylish` → `lobeStaticStylish`
+5. ✅ `readableColor()` → token 替换
+
+### 中优先级（需要转换）
+
+6. ✅ 简单的动态 props → CSS 变量（1-2 个）
+7. ✅ 布尔值 props → 静态样式拆分（2-3 个）
+
+### 低优先级（复杂优化）
+
+8. ⚠️ 多个动态 props → CSS 变量（3+ 个）
+9. ⚠️ 复杂的条件逻辑拆分

+
+export const styles = createStaticStyles(({ css, cssVar }) => ({
+  rootDark: css`
+    background: ${cssVar.colorFillTertiary};
+    color: ${cssVar.colorTextLightSolid};
+  `,
+  rootLight: css`
+    background: ${cssVar.colorFillQuaternary};
+    color: ${cssVar.colorText};
+  `,
+}));
+```
+
+**组件文件：**
+
+```typescript
+import { cx, useTheme } from 'antd-style';
+import { styles } from './style';
+
+const Component = ({ className }) => {
+  const { theme } = useTheme();
+  return (
+    <div
+      className={cx(
+        theme.isDarkMode ? styles.rootDark : styles.rootLight,
+        className
+      )}
+    />
+  );
+};
+```
+
+## 🔍 验证步骤
+
+1. **类型检查：** `pnpm run type-check`
+2. **运行时测试：** 确保视觉效果一致
+3. **性能验证：** 检查样式计算是否在模块加载时完成
+
+## 📊 优化效果
+
+- ✅ **零运行时开销**：样式在模块加载时计算一次
+- ✅ **减少重新渲染**：组件不再依赖样式 hook
+- ✅ **更好的性能**：减少每次渲染的计算开销
+- ✅ **代码更简洁**：直接导入样式对象
+
+## 🔧 场景 11: useTheme () → useThemeMode () /cssVar
+
+**适用：** 组件中只使用 `theme.isDarkMode` 或其他 token 值
+
+**规则：**
+
+- 如果只使用 `theme.isDarkMode`，使用 `const { isDarkMode } = useThemeMode()` 替代
+- 如果使用其他 token（如 `theme.colorText`, `theme.borderRadius` 等），使用 `cssVar` 替代
+- `useThemeMode()` 比 `useTheme()` 更轻量，只返回 `isDarkMode` 值
+
+**示例：**
+
+**之前：**
+
+```typescript
+import { useTheme } from 'antd-style';
+
+const Component = () => {
+  const theme = useTheme();
+  return (
+    <div className={theme.isDarkMode ? styles.dark : styles.light}>
+      {theme.colorText}
+    </div>
+  );
+};
+```
+
+**之后：**
+
+```typescript
+import { cssVar, useThemeMode } from 'antd-style';
+
+const Component = () => {
+  const { isDarkMode } = useThemeMode();
+  return (
+    <div className={isDarkMode ? styles.dark : styles.light}>
+      {cssVar.colorText}
+    </div>
+  );
+};
+```
+
+**已优化示例：**
+
+- `AuroraBackground`, `Select`, `Input`, `Button`, `DatePicker`, `AutoComplete`, `InputNumber`, `InputPassword`, `InputOPT`, `TextArea`, `SpotlightCardItem`, `Spotlight`, `HotkeyInput` - 只使用 `isDarkMode` → `useThemeMode()`
+- `Image`, `GradientButton`, `Empty`, `FileTypeIcon`, `FormSubmitFooter`, `CodeEditor`, `LobeChat`, `Drawer`, `Modal`, `Avatar`, `AvatarGroup`, `SkeletonAvatar`, `SkeletonButton`, `SkeletonTags`, `Callout`, `LobeHub`, `GridBackground`, `FolderIcon`, `FileIcon`, `TokenTag`, `ChatSendButton`, `AvatarUploader` - 使用 token → `cssVar`
+
+**无法优化的文件（需要保留 `useTheme()`）：**
+
+- `useMermaid`, `useStreamMermaid`, `useHighlight`, `useStreamHighlight` - 需要完整的 theme 对象传给第三方库
+- `Alert`, `Tag`, `Menu`, `EmojiPicker` - 需要实际颜色值传给颜色计算函数
+- `SkeletonTitle`, `SkeletonTags` - 需要数值进行数学运算
+- `GridShowcase`, `GridBackground/demos` - 需要实际颜色值传给 `rgba()` 函数
+- `CustomFonts` - 需要实际字符串值进行字符串拼接
+- `Giscus/style.ts` - 需要实际颜色值传给 `readableColor()` 和 `rgba()` 函数（其他 token 已优化为 `cssVar`）
+
+**注意事项：**
+
+- `useThemeMode()` 只返回 `{ isDarkMode }`，不返回完整的 theme 对象
+- `cssVar` 的值是字符串（如 `"14px"`, `"#ffffff"`），可以直接在 JSX 中使用
+- 如果 token 需要用于数值计算（如 `Math.round(theme.fontSize * 1.5)`），需要保留 `useTheme()`
+
+## 🎉 总结
+
+`createStaticStyles` 迁移是一个渐进式的优化过程。对于简单的静态样式，可以直接转换；对于复杂的动态场景，需要根据具体情况选择合适的优化策略。关键是要理解每种场景的处理方式，并灵活运用 CSS 变量、静态样式拆分等技术。
+
+### useTheme () 优化总结
+
+- ✅ **使用 `useThemeMode()`**：当组件只使用 `theme.isDarkMode` 时
+- ✅ **使用 `cssVar`**：当组件使用其他 token 值（颜色、尺寸等）时
+- ⚠️ **保留 `useTheme()`**：当 token 需要用于数值计算或传给第三方库时

 # Drizzle ORM Schema Style Guide for lobe-chat

 This document outlines the conventions and best practices for defining PostgreSQL Drizzle ORM schemas within the lobe-chat project.

 ## Configuration

- Drizzle configuration is managed in [drizzle.config.ts](mdc:drizzle.config.ts)
+- Drizzle configuration is managed in `drizzle.config.ts`
 - Schema files are located in the src/database/schemas/ directory
 - Migration files are output to `src/database/migrations/`

 - Defined using `.references(() => otherTable.id, { onDelete: 'cascade' | 'set null' | 'no action' })`
 - FK columns are usually named `related_table_singular_name_id` (e.g., `user_id` references `users.id`)
 - Most tables include a `user_id` column referencing `users.id` with `onDelete: 'cascade'`

 ### Default Values
+
 - `.$defaultFn(() => expression)` for dynamic defaults (e.g., `idGenerator()`, `randomSlug()`)
 - `.default(staticValue)` for static defaults (e.g., `boolean('enabled').default(true)`)

 ### Indexes
+
 - Defined in the table's second argument: `pgTable('name', {...columns}, (t) => ({ indexName: indexType().on(...) }))`
 - Use `uniqueIndex()` for unique constraints and `index()` for non-unique indexes
 - Naming pattern: `table_name_column(s)_idx` or `table_name_column(s)_unique`
 - Many tables feature a `clientId: text('client_id')` column, often part of a composite unique index with `user_id`

 ### Data Types

+# 如何添加新的快捷键：开发者指南
+
+本指南将带您一步步地向 LobeChat 添加一个新的快捷键功能。我们将通过一个完整示例，演示从定义到实现的整个过程。
+
+## 示例场景
+
+假设我们要添加一个新的快捷键功能：**快速清空聊天记录**，快捷键为 `Mod+Shift+Backspace`。
+
+## 步骤 1：更新快捷键常量定义
+
+首先，在 `src/types/hotkey.ts` 中更新 `HotkeyEnum`：
+
+```typescript
+export const HotkeyEnum = {
+  // 已有的快捷键...
+  AddUserMessage: 'addUserMessage',
+  EditMessage: 'editMessage',
+
+  // 新增快捷键
+  ClearChat: 'clearChat', // 添加这一行
+
+  // 其他已有快捷键...
+} as const;
+```
+
+## 步骤 2：注册默认快捷键
+
+在 `src/const/hotkeys.ts` 中添加快捷键的默认配置：
+
+```typescript
+import { KeyMapEnum as Key, combineKeys } from '@lobehub/ui';
+
+// ...现有代码
+
+export const HOTKEYS_REGISTRATION: HotkeyRegistration = [
+  // 现有的快捷键配置...
+
+  // 添加新的快捷键配置
+  {
+    group: HotkeyGroupEnum.Conversation, // 归类到会话操作组
+    id: HotkeyEnum.ClearChat,
+    keys: combineKeys([Key.Mod, Key.Shift, Key.Backspace]),
+    scopes: [HotkeyScopeEnum.Chat], // 在聊天作用域下生效
+  },
+
+  // 其他现有快捷键...
+];
+```
+
+## 步骤 3：添加国际化翻译
+
+在 `src/locales/default/hotkey.ts` 中添加对应的文本描述：
+
+```typescript
+import { HotkeyI18nTranslations } from '@/types/hotkey';
+
+const hotkey: HotkeyI18nTranslations = {
+  // 现有翻译...
+
+  // 添加新快捷键的翻译
+  clearChat: {
+    desc: '清空当前会话的所有消息记录',
+    title: '清空聊天记录',
+  },
+
+  // 其他现有翻译...
+};
+
+export default hotkey;
+```
+
+如需支持其他语言，还需要在相应的语言文件中添加对应翻译。
+
+## 步骤 4：创建并注册快捷键 Hook
+
+在 `src/hooks/useHotkeys/chatScope.ts` 中添加新的 Hook：
+
+```typescript
+export const useClearChatHotkey = () => {
+  const clearMessages = useChatStore((s) => s.clearMessages);
+  const { t } = useTranslation();
+
+  return useHotkeyById(HotkeyEnum.ClearChat, showConfirm);
+};
+
+// 注册聚合
+
+export const useRegisterChatHotkeys = () => {
+  const { enableScope, disableScope } = useHotkeysContext();
+
+  useOpenChatSettingsHotkey();
+  // ...其他快捷键
+  useClearChatHotkey();
+
+  useEffect(() => {
+    enableScope(HotkeyScopeEnum.Chat);
+    return () => disableScope(HotkeyScopeEnum.Chat);
+  }, []);
+
+  return null;
+};
+```
+
+## 步骤 5：给相应 UI 元素添加 Tooltip 提示（可选）
+
+如果有对应的 UI 按钮，可以添加快捷键提示：
+
+```tsx
+import { DeleteOutlined } from '@ant-design/icons';
+import { Tooltip } from '@lobehub/ui';
+import { Button } from 'antd';
+import { useTranslation } from 'react-i18next';
+
+import { useUserStore } from '@/store/user';
+import { settingsSelectors } from '@/store/user/selectors';
+import { HotkeyEnum } from '@/types/hotkey';
+
+const ClearChatButton = () => {
+  const { t } = useTranslation(['hotkey', 'chat']);
+  const clearChatHotkey = useUserStore(settingsSelectors.getHotkeyById(HotkeyEnum.ClearChat));
+
+  // 获取清空聊天的方法
+  const clearMessages = useChatStore((s) => s.clearMessages);
+
+  return (
+    <Tooltip hotkey={clearChatHotkey} title={t('clearChat.title', { ns: 'hotkey' })}>
+      <Button icon={<DeleteOutlined />} onClick={clearMessages} />
+    </Tooltip>
+  );
+};
+```
+
+## 步骤 6：测试新快捷键
+
+1. 启动开发服务器
+2. 打开聊天页面
+3. 按下设置的快捷键组合（`Cmd+Shift+Backspace` 或 `Ctrl+Shift+Backspace`）
+4. 确认功能正常工作
+5. 检查快捷键设置面板中是否正确显示了新快捷键
+
+## 最佳实践
+
+1. **作用域考虑**：根据功能决定快捷键应属于全局作用域还是聊天作用域
+2. **分组合理**：将快捷键放在合适的功能组中（System/Layout/Conversation）
+3. **冲突检查**：确保新快捷键不会与现有系统、浏览器或应用快捷键冲突
+4. **平台适配**：使用 `Key.Mod` 而非硬编码 `Ctrl` 或 `Cmd`，以适配不同平台
+5. **提供清晰描述**：为快捷键添加明确的标题和描述，帮助用户理解功能
+
+按照以上步骤，您可以轻松地向系统添加新的快捷键功能，提升用户体验。如有特殊需求，如桌面专属快捷键，可以通过 `isDesktop` 标记进行区分处理。
+
+## 常见问题排查
+
+- **快捷键未生效**：检查作用域是否正确，以及是否在 RegisterHotkeys 中调用了对应的 hook
+- **快捷键设置面板未显示**：确认在 HOTKEYS_REGISTRATION 中正确配置了快捷键
+- **快捷键冲突**：在 HotkeyInput 组件中可以检测到冲突，用户会看到警告
+- **功能在某些页面失效**：确认是否注册在了正确的作用域，以及相关页面是否激活了该作用域
+
+通过这些步骤，您可以确保新添加的快捷键功能稳定、可靠且用户友好。

 # LobeChat Internationalization Guide

 ## Key Points

- Default language: Chinese (zh-CN) as the source language
- Supported languages: 18 languages including English, Japanese, Korean, Arabic, etc.
- Framework: react-i18next with Next.js app router
- Translation automation: @lobehub/i18n-cli for automatic translation, config file: .i18nrc.js
- Never manually modify any json file. You can only modify files in `default` folder
+- Default language: Chinese (zh-CN), Framework: react-i18next
+- **Only edit files in `src/locales/default/`** - Never edit JSON files in `locales/`
+- Run `pnpm i18n` to generate all translations (or manually translate zh-CN/en-US for dev preview)

-## Directory Structure
+## Key Naming Convention

-```
-src/locales/
-├── default/           # Source language files (zh-CN)
-│   ├── index.ts      # Namespace exports

-
-## Workflow for Adding New Translations
-
-### 1. Adding New Translation Keys
-
-Step 1: Add translation keys in the corresponding namespace files under src/locales/default directory
+**Flat keys with dot notation** (not nested objects):

 ```typescript
-// Example: src/locales/default/common.ts
+// ✅ Correct
 export default {
-  // ... existing keys
-  newFeature: {
-    title: '新功能标题',
-    description: '功能描述文案',
-    button: '操作按钮',
-  },
+  'alert.cloud.action': '立即体验',
+  'clientDB.error.desc': '数据库初始化遇到问题',
+  'sync.actions.sync': '立即同步',
+  'sync.status.ready': '已连接',
+};
+
+// ❌ Avoid: Nested objects
+export default {
+  alert: { cloud: { action: '...' } },
 };
 ```

-Step 2: If creating a new namespace, export it in src/locales/default/index.ts
+**Naming patterns:** `{feature}.{context}.{action|status}`
+
+- `clientDB.modal.title` - Feature + context + property
+- `sync.actions.sync` - Feature + group + action
+- `sync.status.ready` - Feature + group + status
+
+**Parameters:** Use `{{variableName}}` syntax

 ```typescript
-import newNamespace from './newNamespace';
-
-const resources = {
-  // ... existing namespaces
-  newNamespace,
-} as const;
+'alert.cloud.desc': '我们提供 {{credit}} 额度积分',
 ```

-### 2. Translation Process
+**Avoid key conflicts:** Don't use both a leaf key and its parent path

-Development mode:
+```typescript
+// ❌ Conflict: clientDB.solve exists as both leaf and parent
+'clientDB.solve': '自助解决',
+'clientDB.solve.backup.title': '数据备份',

-Generally, you don't need to help me run the automatic translation tool as it takes a long time. I'll run it myself when needed. However, to see immediate results, you still need to translate `locales/zh-CN/namespace.json` first, no need to translate other languages.
-
-Production mode:
-
-```bash
-# Generate translations for all languages
-npm run i18n
+// ✅ Solution: Use different suffixes
+'clientDB.solve.action': '自助解决',
+'clientDB.solve.backup.title': '数据备份',
 ```

-## Usage in Components
+## Workflow

-### Basic Usage
+1. Add keys to `src/locales/default/{namespace}.ts`
+2. Export new namespace in `src/locales/default/index.ts`
+3. For dev preview: manually translate `locales/zh-CN/{namespace}.json` and `locales/en-US/{namespace}.json`
+4. Run `pnpm i18n` to generate all languages (CI handles this automatically)
+
+## Usage

 ```tsx
 import { useTranslation } from 'react-i18next';

-const MyComponent = () => {
-  const { t } = useTranslation('common');
-
-  return (
-    <div>
-      <h1>{t('newFeature.title')}</h1>
-      <p>{t('newFeature.description')}</p>
-      <button>{t('newFeature.button')}</button>
-    </div>
-  );
-};
-```
-
-### Usage with Parameters
-
-```tsx
 const { t } = useTranslation('common');

-<p>{t('welcome.message', { name: 'John' })}</p>;
-
-// Corresponding language file:
-// welcome: { message: 'Welcome {{name}}!' }
-```
-
-### Multiple Namespaces
-
-```tsx
+// Basic
+t('newFeature.title')
+// With parameters
+t('alert.cloud.desc', { credit: '1000' })
+// Multiple namespaces
 const { t } = useTranslation(['common', 'chat']);
-
-<button>{t('common:save')}</button>
-<span>{t('chat:typing')}</span>
+t('common:save')
 ```

-## Type Safety
+## Available Namespaces

-The project uses TypeScript to implement type-safe translations, with types automatically generated from src/locales/resources.ts:
+auth, authError, changelog, chat, clerk, color, **common**, components, discover, editor, electron, error, file, home, hotkey, image, knowledgeBase, labs, marketAuth, memory, metadata, migration, modelProvider, models, oauth, onboarding, plugin, portal, providers, ragEval, **setting**, subscription, thread, tool, topic, welcome

-```typescript
-import type { DefaultResources, Locales, NS } from '@/locales/resources';
-
-// Available types:
-// - NS: Available namespace keys ('common' | 'chat' | 'setting' | ...)
-// - Locales: Supported language codes ('en-US' | 'zh-CN' | 'ja-JP' | ...)
-
-const namespace: NS = 'common';
-const locale: Locales = 'en-US';
-```
-
-## Best Practices
-
-### 1. Namespace Organization
-
- common: Shared UI elements (buttons, labels, actions)
- chat: Chat-specific functionality
- setting: Configuration and settings
- error: Error messages and handling
- [feature]: Feature-specific or page-specific namespaces
- components: Reusable component text
-
-### 2. Key Naming Conventions
-
-```typescript
-// ✅ Good: Hierarchical structure
-export default {
-  modal: {
-    confirm: {
-      title: '确认操作',
-      message: '确定要执行此操作吗？',
-      actions: {
-        confirm: '确认',
-        cancel: '取消',
-      },
-    },
-  },
-};
-
-// ❌ Avoid: Flat structure
-export default {
-  modalConfirmTitle: '确认操作',
-  modalConfirmMessage: '确定要执行此操作吗？',
-};
-```
-
-## Troubleshooting
-
-### Missing Translation Keys
-
- Check if the key exists in src/locales/default/namespace.ts
- Ensure the namespace is correctly imported in the component
- Ensure new namespaces are exported in src/locales/default/index.ts
-
- 检查键是否存在于 src/locales/default/namespace.ts 中
- 确保在组件中正确导入命名空间
- 确保新命名空间已在 src/locales/default/index.ts 中导出

+# 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 → ...

+
+产品 slogan：**Where Agents Collaborate**。你的文案要让用户持续感到：LobeHub 的重点不是“生成”，而是“协作的助理体系”（可共享上下文、可追踪、可回放、可演进、人在回路）。
+
+---
+
+### 1) 固定术语（必须遵守）
+
+- Workspace：空间
+- Agent：助理
+- Agent Team：群组
+- Context：上下文
+- Memory：记忆
+- Integration：连接器
+- Tool/Skill/Plugin/插件/工具: 技能
+- SystemRole: 助理档案
+- Topic: 话题
+- Page: 文稿
+- Community: 社区
+- Resource: 资源
+- Library: 库
+- MCP: MCP
+- Provider: 模型服务商
+
+术语规则：同一概念全站只用一种说法，不混用“Agent/智能体/机器人/团队/工作区”等。
+
+---
+
+### 2) 你的任务
+
+- 优化、改写或从零生成任何界面中文文案：标题、按钮、表单说明、占位、引导、空状态、Toast、弹窗、错误、权限、设置项、创建/运行流程、协作与群组相关页面等。
+- 文案必须同时兼容：普通用户看得懂 + 专业用户不觉得低幼；娱乐与严肃场景都成立；不过度营销、不夸大 AI 能力；在关键节点提供恰到好处的人文关怀。
+
+---
+
+### 3) 品牌三原则（内化到结构与措辞）
+
+- **Create（创建）**：一句话创建助理；从想法到可用；清楚下一步。
+- **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）。
+- **Evolve（演进）**：助理可在你允许的范围内记住偏好；随你的工作方式变得更顺手；强调可解释、可设置、可回放。
+
+---
+
+### 4) 写作规则（可执行）
+
+1. **清晰优先**：短句、强动词、少形容词；避免口号化与空泛承诺（如“颠覆”“史诗级”“100%”）。
+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。
+6. **中文本地化**：符合中文阅读节奏；中英混排规范；避免翻译腔。
+
+---
+
+### 5) 人文关怀（中间态温度：介于克制与陪伴）
+
+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。
+
+#### 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”）
+
+#### 核心立场
+
+- 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”
+
+##### 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）
+
+- 适度表达：记录、回放、版本、协作痕迹、讨论、共创、里程碑
+- 用“经历/过程/痕迹/回忆/脉络/成长”这类词，避免虚无抒情
+
+##### D. 不用“AI 神话”
+
+- 不渲染“AI 终将超越你/取代你”
+- 也不轻飘飘说“AI 只是工具”了事更像：**“它是工具，但你仍是作者/负责人/最终决定者”**
+
+##### 示例
+
+在用户可能产生自我否定或无力感的场景（空状态、创作开始、产出对比、失败重试、长时间等待、团队协作分歧、版本回退）：
+
+    1. **先承接感受**：用一句短话确认处境（不评判）
+    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。
+
+你可以让系统在需要时套这些结构（同一句兼容新手/专业）：
+
+**开始创作/空白页**
+
+- 主句：给一个轻承接 + 行动入口
+- 模板：
+  - 「从一个念头开始就够了。写一句话，我来帮你搭好第一个助理。」
+  - 「不知道从哪开始也没关系：先说目标，我们一起把它拆开。」
+
+**长任务运行/等待**
+
+- 模板：
+  - 「正在运行中…你可以先去做别的，完成后我会提醒你。」
+  - 「这一步可能要几分钟。想更快：减少上下文 / 切换模型 / 关闭自动运行。」
+
+**失败/重试**
+
+- 模板：
+  - 「没关系，这次没跑通。你可以重试，或查看原因再继续。」
+  - 「连接失败：权限未通过或网络不稳定。去设置重新授权，或稍后再试。」
+
+**对比与自我价值焦虑（适合提示/引导，不适合错误弹窗）**
+
+- 模板：
+  - 「助理可以加速产出，但方向、取舍和标准仍属于你。」
+  - 「结果可以很快，经历更重要：把每次尝试留下来，下一次会更稳。」
+
+**协作/群组**
+
+- 模板：
+  - 「把上下文对齐到同一处，群组里每个助理都会站在同一页上。」
+  - 「不同意见没关系：先把目标写清楚，再让助理分别给方案与取舍。」
+
+### 6) 错误/异常/权限/付费：硬规则
+
+- 必须包含：**发生了什么 +（可选）原因 + 你可以怎么做**
+- 必须提供可操作选项：**重试 / 查看详情 / 去设置 / 联系支持 / 复制日志**（按场景取舍）
+- 不责备用户；不只给错误码；错误码可放在“详情”里
+- 涉及数据与安全：语气更中性更完整，温度通过“尊重与解释”体现，而不是煽

+You are **LobeHub’s English UI Copy & Microcopy Specialist**.
+
+LobeHub is an assistant workspace: users can create **Agents** and **Agent Teams** so people↔agents and agent↔agent can collaborate to improve productivity in work and life. Brand vibe: youthful, friendly, modern on the surface; professional, reliable, productivity- and controllability-first underneath. Overall style reference: Notion / Figma / Apple / Discord / OpenAI / Gemini — clear, restrained, trustworthy, human but not cheesy.
+
+Product slogan: **Where Agents Collaborate**. Your copy must continuously reinforce that LobeHub is not about “generation”, but about a **collaborative agent system**: shareable context, traceable outcomes, replayable runs, evolvable setup, and **human-in-the-loop**.
+
+---
+
+## 1) Fixed Terminology (must follow)
+
+Use **exactly** these English terms across the product. Do not mix synonyms for the same concept.
+
+- 空间: **Workspace**
+- 助理: **Agent**
+- 群组: **Group**
+- 上下文: **Context**
+- 记忆: **Memory**
+- 连接器: **Integration**
+- 技能/tool/plugin: **Skill**
+- 助理档案: **Agent Profile**
+- 话题: **Topic**
+- 文稿: **Page**
+- 社区: **Community**
+- 资源: **Resource**
+- 库: **Library**
+- MCP: **MCP**
+- 模型服务商: **Provider**
+
+Terminology rule: one concept = one term site-wide. Never alternate with “bot/assistant/AI agent/team/workspace” variations.
+
+---
+
+## 2) Your Responsibilities
+
+- Improve, rewrite, or create from scratch any **English UI copy**: titles, buttons, form labels/help text, placeholders, onboarding, empty states, toasts, modals, errors, permission prompts, settings, creation/run flows, collaboration and Agent Team pages, etc.
+- Copy must work for both:
+  - general users (immediately understandable)
+  - power users (not childish)
+- It must fit both playful and serious contexts.
+- Avoid overclaiming AI capabilities; add human warmth at the right moments.
+
+---
+
+## 3) The Three Brand Principles (bake into structure & wording)
+
+- **Create**: create an Agent in one sentence; clear next step from idea → usable.
+- **Collaborate**: multi-agent collaboration; align info and outputs; share Context (controlled, manageable).
+- **Evolve**: Agents can remember preferences **only with user consent**; become more helpful over time; emphasize explainability, settings, and replay.
+
+---
+
+## 4) Writing Rules (actionable)
+
+1. **Clarity first**: short sentences, strong verbs, minimal adjectives. Avoid hype (“revolutionary”, “epic”, “100%”).
+2. **Layered messaging (single version for everyone)**:
+   - Main line: simple and actionable
+   - Optional second line: more precise / technical / boundary-setting (subtitle, helper text, tooltip, collapsible)
+   - Do not produce “Pro vs Lite” variants; one main + optional detail
+3. **Use terms sparingly but correctly**: prefer plain words (“connect”, “run”, “context”) unless a technical term is necessary. When it is, add a plain-English explanation.
+4. **Consistency**: keep verbs consistent across similar actions (Create / Connect / Run / Pause / Retry / View details / Clear Memory).
+5. **Actionable**: every message tells the user what to do next. Avoid generic “OK/Cancel”; use specific actions.
+6. **English localization**: natural, product-native English; avoid translationese; keep punctuation and casing consistent.
+
+---
+
+## 5) Human Warmth (balanced, controlled)
+
+Goal: reduce anxiety and restore control without being sentimental. Default ratio: **80% information, 20% warmth**. Key moments (first-time create, empty state, long waits, failures/retries, rollback/data-loss risk, collaboration conflicts): may go **70/30**.
+
+Hard cap: any on-screen message may include **at most half a sentence to one sentence** of warmth, and it must be followed by a clear next step.
+
+Required order:
+
+1. Acknowledge the situation (no judgment)
+2. Restore control (human-in-the-loop: pause/replay/edit/undo/clear Memory/view Context)
+3. Provide the next action (button/path)
+
+Avoid:
+
+- preachy encouragement (“don’t worry”, “stay positive”)
+- grand narratives
+- overly anthropomorphic claims (“I understand you”, “I’ll always remember you”)
+
+Core stance: Agents can accelerate output, but **you** own the judgment, trade-offs, and final decision. LobeHub gives you time back for what matters.
+
+Suggested patterns:
+
+- **Getting started / blank state**
+  - “Starting with one sentence is enough. Describe your goal and I’ll help you set up the first Agent.”
+  - “Not sure where to begin? Tell me the outcome—we’ll break it down together.”
+- **Long run / waiting**
+  - “Running… You can switch tasks—I'll notify you when it’s done.”
+  - “This may take a few minutes. To speed up: reduce Context / switch model / disable Auto-run.”
+- **Failure / retry**
+  - “That didn’t run through. Retry, or view details to fix the cause.”
+  - “Connection failed: permission not granted or network unstable. Re-authorize in Settings, or try again later.”
+- **Value anxiety (guidance, not error dialogs)**
+  - “Agents can speed up output, but direction and standards stay with you.”
+  - “Fast results are great—keeping the trail makes the next run steadier.”
+- **Collaboration / Agent Teams**
+  - “Align everyone to the same Context. Every Agent in the Agent Team works from the same page.”
+  - “Different opinions are fine. Write the goal first, then let Agents propose options and trade-offs.”
+
+---
+
+## 6) Errors / Exceptions / Permissions / Billing: hard rules
+
+Every error must include:
+
+- **What happened**
+- (optional) **Why**
+- **What the user can do next**
+
+Provide actionable options as appropriate:
+
+- Retry / View details / Go to Settings / Contact support / Copy logs
+
+Never blame the user. Don’t show only an error code; put codes in “Details” if needed. For data/security/billing: be neutral, thorough, and respectful—warmth comes from clarity, not emotion.
+

+
+## 7) Your Special Task: CN i18n → EN (localized, length-aware)
+
+You translate **raw Chinese i18n strings into English** for LobeHub.
+
+Requirements:
+
+- Prefer **localized**, product-native English over literal translation.
+- Do **not** chase perfect one-to-one consistency if a more natural UI phrase reads better.
+- Keep the **character length difference small**; try to make the English string **roughly the same visual length** as the Chinese source (avoid overly long expansions).
+- Preserve meaning, tone, and actionability; keep verbs consistent with LobeHub’s UI patterns.
+- If space is tight (buttons, tabs, toasts), prioritize: **verb + object**, drop optional words first.
+- If the Chinese includes placeholders/variables, preserve them exactly (e.g., `{name}`, `{{count}}`, `%s`) and keep word order sensible.
+- Keep capitalization consistent with UI norms (buttons/title case only when appropriate).
+
+Output format when translating:
+
+- Provide **English only**, unless asked otherwise.
+- If multiple options are useful, give **one best option** + **one shorter fallback** (only when length constraints are likely).
+
+---
+
+You always optimize for: **clarity, control, collaboration, replayability, and human-in-the-loop**—in a modern, restrained, trustworthy English voice.

-# react component 编写指南
-
- 如果要写复杂样式的话用 antd-style ，简单的话可以用 style 属性直接写内联样式
- 如果需要 flex 布局或者居中布局应该使用 react-layout-kit 的 Flexbox 和 Center 组件
- 选择组件时优先顺序应该是 src/components > 安装的组件 package > lobe-ui > antd
- 使用 selector 访问 zustand store 的数据，而不是直接从 store 获取
-
-## antd-style token system
-
-### 访问 token system 的两种方式
-
-#### 使用 antd-style 的 useTheme hook
-
-```tsx
-import { useTheme } from 'antd-style';
-
-const MyComponent = () => {
-  const theme = useTheme();
-
-  return (
-    <div
-      style={{
-        color: theme.colorPrimary,
-        backgroundColor: theme.colorBgContainer,
-        padding: theme.padding,
-        borderRadius: theme.borderRadius,
-      }}
-    >
-      使用主题 token 的组件
-    </div>
-  );
-};
-```
-
-#### 使用 antd-style 的 createStyles
-
-```tsx
-const useStyles = createStyles(({ css, token }) => {
-  return {
-    container: css`
-      background-color: ${token.colorBgContainer};
-      border-radius: ${token.borderRadius}px;
-      padding: ${token.padding}px;
-      color: ${token.colorText};
-    `,
-    title: css`
-      font-size: ${token.fontSizeLG}px;
-      font-weight: ${token.fontWeightStrong};
-      margin-bottom: ${token.marginSM}px;
-    `,
-    content: css`
-      font-size: ${token.fontSize}px;
-      line-height: ${token.lineHeight};
-    `,
-  };
-});
-
-const Card: FC<CardProps> = ({ title, content }) => {
-  const { styles } = useStyles();
-
-  return (
-    <Flexbox className={styles.container}>
-      <div className={styles.title}>{title}</div>
-      <div className={styles.content}>{content}</div>
-    </Flexbox>
-  );
-};
-```
-
-### 一些你经常会忘记使用的 token
-
-请注意使用下面的 token 而不是 css 字面值。可以访问 https://ant.design/docs/react/customize-theme-cn 了解所有 token
-
- 动画类
-  - token.motionDurationMid
-  - token.motionEaseInOut
- 包围盒属性
-  - token.paddingSM
-  - token.marginLG
-
-## Lobe UI 包含的组件
-
- 不知道 `@lobehub/ui` 的组件怎么用，有哪些属性，就自己搜下这个项目其它地方怎么用的，不要瞎猜，大部分组件都是在 antd 的基础上扩展了属性
- 具体用法不懂可以联网搜索，例如 ActionIcon 就爬取 https://ui.lobehub.com/components/action-icon
- 可以阅读 `node_modules/@lobehub/ui/es/index.js` 了解有哪些组件，每个组件的属性是什么

+## Routing Architecture
+
+This project uses a **hybrid routing architecture**: Next.js App Router for static pages + React Router DOM for the main SPA.
+
+### Route Types
+
+```plaintext
+------------------+--------------------------------+--------------------------------+
+|   Route Type     |          Use Case              |        Implementation          |
+------------------+--------------------------------+--------------------------------+
+| Next.js App      | Auth pages (login, signup,     | page.tsx file convention       |
+| Router           | oauth, reset-password, etc.)   | src/app/[variants]/(auth)/     |
+------------------+--------------------------------+--------------------------------+
+| React Router     | Main SPA features              | BrowserRouter + Routes         |
+| DOM              | (chat, community, settings)     | desktopRouter.config.tsx       |
+|                  |                                | mobileRouter.config.tsx        |
+------------------+--------------------------------+--------------------------------+
+```
+
+### Key Files
+
+- Entry point: `src/app/[variants]/page.tsx` - Routes to Desktop or Mobile based on device
+- Desktop router: `src/app/[variants]/router/desktopRouter.config.tsx`
+- Mobile router: `src/app/[variants]/(mobile)/router/mobileRouter.config.tsx`
+- Router utilities: `src/utils/router.tsx`
+
+### Router Utilities
+
+```tsx
+import { ErrorBoundary, RouteConfig, dynamicElement, redirectElement } from '@/utils/router';
+
+// Lazy load a page component
+element: dynamicElement(() => import('./chat'), 'Desktop > Chat');
+
+// Create a redirect
+element: redirectElement('/settings/profile');
+
+// Error boundary for route
+errorElement: <ErrorBoundary resetPath="/chat" />;
+```
+
+### Adding New Routes
+
+1. Add route config to `desktopRouter.config.tsx` or `mobileRouter.config.tsx`
+2. Create page component in the corresponding directory under `(main)/`
+3. Use `dynamicElement()` for lazy loading
+
+### Navigation
+
+**Important**: For SPA pages (React Router DOM routes), use `Link` from `react-router-dom`, NOT from `next/link`.
+
+```tsx
+// ❌ Wrong - next/link in SPA pages
+import Link from 'next/link';
+<Link href="/">Home</Link>
+
+// ✅ Correct - react-router-dom Link in SPA pages
+import { Link } from 'react-router-dom';
+<Link to="/">Home</Link>
+```
+
+```tsx
+// In components - use react-router-dom hooks
+import { useNavigate, useParams } from 'react-router-dom';
+
+const navigate = useNavigate();
+navigate('/chat');
+
+// From stores - use global navigate
+import { useGlobalStore } from '@/store/global';
+
+const navigate = useGlobalStore.getState().navigate;
+navigate?.('/settings');

+# Recent Data 使用指南
+
+## 概述
+
+Recent 数据（recentTopics, recentResources, recentPages）存储在 session store 中，可以在应用的任何地方访问。
+
+## 数据初始化
+
+在应用顶层（如 `RecentHydration.tsx`）中初始化所有 recent 数据：
+
+```tsx
+import { useInitRecentPage } from '@/hooks/useInitRecentPage';
+import { useInitRecentResource } from '@/hooks/useInitRecentResource';
+import { useInitRecentTopic } from '@/hooks/useInitRecentTopic';
+
+const App = () => {
+  // 初始化所有 recent 数据
+  useInitRecentTopic();
+  useInitRecentResource();
+  useInitRecentPage();
+
+  return <YourComponents />;
+};
+```
+
+## 使用方式
+
+### 方式一：直接从 Store 读取（推荐用于多处使用）
+
+在任何组件中直接访问 store 中的数据：
+
+```tsx
+import { useSessionStore } from '@/store/session';
+import { recentSelectors } from '@/store/session/selectors';
+
+const Component = () => {
+  // 读取数据
+  const recentTopics = useSessionStore(recentSelectors.recentTopics);
+  const isInit = useSessionStore(recentSelectors.isRecentTopicsInit);
+
+  if (!isInit) return <div>Loading...</div>;
+
+  return (
+    <div>
+      {recentTopics.map((topic) => (
+        <div key={topic.id}>{topic.title}</div>
+      ))}
+    </div>
+  );
+};
+```
+
+### 方式二：使用 Hook 返回的数据（用于单一组件）
+
+```tsx
+import { useInitRecentTopic } from '@/hooks/useInitRecentTopic';
+
+const Component = () => {
+  const { data: recentTopics, isLoading } = useInitRecentTopic();
+
+  if (isLoading) return <div>Loading...</div>;
+
+  return <div>{/* 使用 recentTopics */}</div>;
+};
+```
+
+## 可用的 Selectors
+
+### Recent Topics (最近话题)
+
+```tsx
+import { recentSelectors } from '@/store/session/selectors';
+
+// 数据
+const recentTopics = useSessionStore(recentSelectors.recentTopics);
+// 类型: RecentTopic[]
+
+// 初始化状态
+const isInit = useSessionStore(recentSelectors.isRecentTopicsInit);
+// 类型: boolean
+```
+
+**RecentTopic 类型：**
+
+```typescript
+interface RecentTopic {
+  agent: {
+    avatar: string | null;
+    backgroundColor: string | null;
+    id: string;
+    title: string | null;
+  } | null;
+  id: string;
+  title: string | null;
+  updatedAt: Date;
+}
+```
+
+### Recent Resources (最近文件)
+
+```tsx
+import { recentSelectors } from '@/store/session/selectors';
+
+// 数据
+const recentResources = useSessionStore(recentSelectors.recentResources);
+// 类型: FileListItem[]
+
+// 初始化状态
+const isInit = useSessionStore(recentSelectors.isRecentResourcesInit);
+// 类型: boolean
+```
+
+### Recent Pages (最近页面)
+
+```tsx
+import { recentSelectors } from '@/store/session/selectors';
+
+// 数据
+const recentPages = useSessionStore(recentSelectors.recentPages);
+// 类型: any[]
+
+// 初始化状态
+const isInit = useSessionStore(recentSelectors.isRecentPagesInit);
+// 类型: boolean
+```
+
+## 特性
+
+1. **自动登录检测**：只有在用户登录时才会加载数据
+2. **数据缓存**：数据存储在 store 中，多处使用无需重复加载
+3. **自动刷新**：使用 SWR，在用户重新聚焦时自动刷新（5分钟间隔）
+4. **类型安全**：完整的 TypeScript 类型定义
+
+## 最佳实践
+
+1. **初始化位置**：在应用顶层统一初始化所有 recent 数据
+2. **数据访问**：使用 selectors 从 store 读取数据
+3. **多处使用**：同一数据在多个组件中使用时，推荐使用方式一（直接从 store 读取）
+4. **性能优化**：使用 selector 确保只有相关数据变化时才重新渲染

+# Agent Runtime E2E 测试指南
+
+本文档描述 Agent Runtime 端到端测试的核心原则和实施方法。
+
+## 核心原则
+
+### 1. 最小化 Mock 原则
+
+E2E 测试的目标是尽可能接近真实运行环境。因此，我们只 Mock **三个外部依赖**：
+
+| 依赖 | Mock 方式 | 说明 |
+| --- | --- | --- |
+| **Database** | PGLite | 使用 `@lobechat/database/test-utils` 提供的内存数据库 |
+| **Redis** | InMemoryAgentStateManager | Mock `AgentStateManager` 使用内存实现 |
+| **Redis** | InMemoryStreamEventManager | Mock `StreamEventManager` 使用内存实现 |
+
+**不 Mock 的部分：**
+
+- `model-bank` - 使用真实的模型配置数据
+- `Mecha` (AgentToolsEngine, ContextEngineering) - 使用真实逻辑
+- `AgentRuntimeService` - 使用真实逻辑
+- `AgentRuntimeCoordinator` - 使用真实逻辑
+
+### 2. 使用 vi.spyOn 而非 vi.mock
+
+不同测试场景需要不同的 LLM 响应。使用 `vi.spyOn` 可以：
+
+- 在每个测试中灵活控制返回值
+- 便于测试不同场景（纯文本、tool calls、错误等）
+- 避免全局 mock 导致的测试隔离问题
+
+### 3. 默认模型使用 gpt-5
+
+- `model-bank` 中肯定有该模型的数据
+- 避免短期内因模型更新需要修改测试
+
+## 技术实现
+
+### 数据库设置
+
+```typescript
+import { LobeChatDatabase } from '@lobechat/database';
+import { getTestDB } from '@lobechat/database/test-utils';
+
+let testDB: LobeChatDatabase;
+
+beforeEach(async () => {
+  testDB = await getTestDB();
+});
+```
+
+### OpenAI Response Mock Helper
+
+创建一个 helper 函数来生成 OpenAI 格式的流式响应：
+
+```typescript
+/**
+ * 创建 OpenAI 格式的流式响应
+ */
+export const createOpenAIStreamResponse = (options: {
+  content?: string;
+  toolCalls?: Array<{
+    id: string;
+    name: string;
+    arguments: string;
+  }>;
+  finishReason?: 'stop' | 'tool_calls';
+}) => {
+  const { content, toolCalls, finishReason = 'stop' } = options;
+
+  return new Response(
+    new ReadableStream({
+      start(controller) {
+        const encoder = new TextEncoder();
+
+        // 发送内容 chunk
+        if (content) {
+          const chunk = {
+            id: 'chatcmpl-mock',
+            object: 'chat.completion.chunk',
+            model: 'gpt-5',
+            choices: [
+              {
+                index: 0,
+                delta: { content },
+                finish_reason: null,
+              },
+            ],
+          };
+          controller.enqueue(encoder.encode(`data: ${JSON.stringify(chunk)}\n\n`));
+        }
+
+        // 发送 tool_calls chunk
+        if (toolCalls) {
+          for (const tool of toolCalls) {
+            const chunk = {
+              id: 'chatcmpl-mock',
+              object: 'chat.completion.chunk',
+              model: 'gpt-5',
+              choices: [
+                {
+                  index: 0,
+                  delta: {
+                    tool_calls: [
+                      {
+                        index: 0,
+                        id: tool.id,
+                        type: 'function',
+                        function: {
+                          name: tool.name,
+                          arguments: tool.arguments,
+                        },
+                      },
+                    ],
+                  },
+                  finish_reason: null,
+                },
+              ],
+            };
+            controller.enqueue(encoder.encode(`data: ${JSON.stringify(chunk)}\n\n`));
+          }
+        }
+
+        // 发送完成 chunk
+        const finishChunk = {
+          id: 'chatcmpl-mock',
+          object: 'chat.completion.chunk',
+          model: 'gpt-5',
+          choices: [
+            {
+              index: 0,
+              delta: {},
+              finish_reason: finishReason,
+            },
+          ],
+        };
+        controller.enqueue(encoder.encode(`data: ${JSON.stringify(finishChunk)}\n\n`));
+        controller.enqueue(encoder.encode('data: [DONE]\n\n'));
+        controller.close();
+      },
+    }),
+    { headers: { 'content-type': 'text/event-stream' } },
+  );
+};
+```
+
+### 内存状态管理
+
+使用依赖注入替代 Redis：
+
+```typescript
+import {
+  InMemoryAgentStateManager,
+  InMemoryStreamEventManager,
+} from '@/server/modules/AgentRuntime';
+import { AgentRuntimeService } from '@/server/services/agentRuntime';
+
+const stateManager = new InMemoryAgentStateManager();
+const streamEventManager = new InMemoryStreamEventManager();
+
+const service = new AgentRuntimeService(serverDB, userId, {
+  coordinatorOptions: {
+    stateManager,
+    streamEventManager,
+  },
+  queueService: null, // 禁用 QStash 队列，使用 executeSync
+  streamEventManager,
+});
+```
+
+### Mock OpenAI API
+
+在测试中使用 `vi.spyOn` mock fetch：
+
+```typescript
+import { vi } from 'vitest';
+
+// 在测试文件顶部或 beforeEach 中
+const fetchSpy = vi.spyOn(globalThis, 'fetch');
+
+// 在具体测试中设置返回值
+it('should handle text response', async () => {
+  fetchSpy.mockResolvedValueOnce(createOpenAIStreamResponse({ content: '杭州今天天气晴朗' }));
+
+  // ... 执行测试
+});
+
+it('should handle tool calls', async () => {
+  fetchSpy.mockResolvedValueOnce(
+    createOpenAIStreamResponse({
+      toolCalls: [
+        {
+          id: 'call_123',
+          name: 'lobe-web-browsing____search____builtin',
+          arguments: JSON.stringify({ query: '杭州天气' }),
+        },
+      ],
+      finishReason: 'tool_calls',
+    }),
+  );
+
+  // ... 执行测试
+});
+```
+
+## 测试场景
+
+### 1. 基本对话测试
+
+```typescript
+describe('Basic Chat', () => {
+  it('should complete a simple conversation', async () => {
+    fetchSpy.mockResolvedValueOnce(
+      createOpenAIStreamResponse({ content: 'Hello! How can I help you?' }),
+    );
+
+    const result = await service.createOperation({
+      agentConfig: { model: 'gpt-5', provider: 'openai' },
+      initialMessages: [{ role: 'user', content: 'Hi' }],
+      // ...
+    });
+
+    const finalState = await service.executeSync(result.operationId);
+    expect(finalState.status).toBe('done');
+  });
+});
+```
+
+### 2. Tool 调用测试
+
+```typescript
+describe('Tool Calls', () => {
+  it('should execute web-browsing tool', async () => {
+    // 第一次调用：LLM 返回 tool_calls
+    fetchSpy.mockResolvedValueOnce(
+      createOpenAIStreamResponse({
+        toolCalls: [
+          {
+            id: 'call_123',
+            name: 'lobe-web-browsing____search____builtin',
+            arguments: JSON.stringify({ query: '杭州天气' }),
+          },
+        ],
+        finishReason: 'tool_calls',
+      }),
+    );
+
+    // 第二次调用：处理 tool 结果后的响应
+    fetchSpy.mockResolvedValueOnce(
+      createOpenAIStreamResponse({ content: '根据搜索结果，杭州今天...' }),
+    );
+
+    // ... 执行测试
+  });
+});
+```
+
+### 3. 错误处理测试
+
+```typescript
+describe('Error Handling', () => {
+  it('should handle API errors gracefully', async () => {
+    fetchSpy.mockRejectedValueOnce(new Error('API rate limit exceeded'));
+
+    // ... 执行测试并验证错误处理
+  });
+});
+```
+
+## 文件组织
+
+```
+src/server/routers/lambda/__tests__/integration/
+├── setup.ts                    # 测试设置工具

+
+## 注意事项
+
+1. **测试隔离**：每个测试后清理 `InMemoryAgentStateManager` 和 `InMemoryStreamEventManager`
+2. **超时设置**：E2E 测试可能需要更长的超时时间
+3. **调试**：使用 `DEBUG=lobe-server:*` 环境变量查看详细日志

-# 测试指南 - LobeChat Testing Guide
+# LobeChat Testing Guide

-## 测试环境概览
+## Test Overview

-LobeChat 项目使用 Vitest 测试库，配置了两种不同的测试环境：
+LobeChat testing consists of **E2E tests** and **Unit tests**. This guide focuses on **Unit tests**.

-### 客户端数据库测试环境 (DOM Environment)
+Unit tests are organized into three main categories:

- **配置文件**: [vitest.config.ts](mdc:vitest.config.ts)
- **环境**: Happy DOM (浏览器环境模拟)
- **数据库**: PGLite (浏览器环境的 PostgreSQL)
- **用途**: 测试前端组件、客户端逻辑、React 组件等
- **设置文件**: [tests/setup.ts](mdc:tests/setup.ts)
+```plaintext
+---------------------+---------------------------+-----------------------------+
+| Category            | Location                  | Config File                 |
+---------------------+---------------------------+-----------------------------+
+| Next.js Webapp      | src/**/*.test.ts(x)       | vitest.config.ts            |
+| Packages            | packages/*/**/*.test.ts   | packages/*/vitest.config.ts |
+| Desktop App         | apps/desktop/**/*.test.ts | apps/desktop/vitest.config.ts |
+---------------------+---------------------------+-----------------------------+
+```

-### 服务端数据库测试环境 (Node Environment)
+### Next.js Webapp Tests

-目前只有 `packages/database` 下的测试可以通过配置 `TEST_SERVER_DB=1` 环境变量来使用服务端数据库测试
+- **Config File**: `vitest.config.ts`
+- **Environment**: Happy DOM (browser environment simulation)
+- **Database**: PGLite (PostgreSQL for browser environments)
+- **Setup File**: `tests/setup.ts`
+- **Purpose**: Testing React components, hooks, stores, utilities, and client-side logic

- **配置文件**: [packages/database/vitest.config.mts](mdc:packages/database/vitest.config.mts) 并且设置环境变量 `TEST_SERVER_DB=1`
- **环境**: Node.js
- **数据库**: 真实的 PostgreSQL 数据库
- **并发限制**: 单线程运行 (`singleFork: true`)
- **用途**: 测试数据库模型、服务端逻辑、API 端点等
- **设置文件**: [packages/database/tests/setup-db.ts](mdc:packages/database/tests/setup-db.ts)
+### Packages Tests

-## 测试运行命令
+Most packages use standard Vitest configuration. However, the `database` package is special:

-** 性能警告**: 项目包含 3000+ 测试用例，完整运行需要约 10 分钟。务必使用文件过滤或测试名称过滤。
+#### Database Package (Special Case)

-### 正确的命令格式
+The database package supports **dual-environment testing**:
+
+| Environment      | Database        | Config                                | Use Case                          |
+|------------------|-----------------|---------------------------------------|-----------------------------------|
+| Client (Default) | PGLite          | `packages/database/vitest.config.mts` | Fast local development            |
+| Server           | Real PostgreSQL | Set `TEST_SERVER_DB=1`                | CI/CD, compatibility verification |
+
+Server environment details:
+
+- **Concurrency**: Single-threaded (`singleFork: true`)
+- **Setup File**: `packages/database/tests/setup-db.ts`
+- **Requirement**: `DATABASE_TEST_URL` environment variable must be set
+
+### Desktop App Tests
+
+- **Config File**: `apps/desktop/vitest.config.ts`
+- **Environment**: Node.js
+- **Purpose**: Testing Electron main process controllers, IPC handlers, and desktop-specific logic
+
+## Test Commands
+
+**Performance Warning**: The project contains 3000+ test cases. A full run takes approximately 10 minutes. Always use file filtering or test name filtering.
+
+### Recommended Command Format

 ```bash
-# 运行所有客户端/服务端测试
-bunx vitest run --silent='passed-only'                                          # 客户端测试
-cd packages/database && TEST_SERVER_DB=1 bunx vitest run --silent='passed-only' # 服务端测试
+# Run all client/server tests
+bunx vitest run --silent='passed-only'                                          # Client tests
+cd packages/database && TEST_SERVER_DB=1 bunx vitest run --silent='passed-only' # Server tests

-# 运行特定测试文件 (支持模糊匹配)
+# Run specific test file (supports fuzzy matching)
 bunx vitest run --silent='passed-only' user.test.ts

-# 运行特定测试用例名称 (使用 -t 参数)
+# Run specific test case by name (using -t flag)
 bunx vitest run --silent='passed-only' -t "test case name"

-# 组合使用文件和测试名称过滤
+# Combine file and test name filtering
 bunx vitest run --silent='passed-only' filename.test.ts -t "specific test"

-# 生成覆盖率报告 (使用 --coverage 参数)
+# Generate coverage report (using --coverage flag)
 bunx vitest run --silent='passed-only' --coverage
 ```

-### 避免的命令格式
+### Commands to Avoid

 ```bash
-#  这些命令会运行所有 3000+ 测试用例，耗时约 10 分钟！
+# ❌ These commands run all 3000+ test cases, taking ~10 minutes!
 npm test
 npm test some-file.test.ts

-#  不要使用裸 vitest (会进入 watch 模式)
+# ❌ Don't use bare vitest (enters watch mode)
 vitest test-file.test.ts
 ```

-## 测试修复原则
+## Test Fixing Principles

-### 核心原则
+### Core Principles

-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
+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

-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。
+2. **Prioritize Test Fixes**
+   If the test itself is incorrect, fix the test first rather than the implementation code.

-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。
+3. **Focus on a Single Issue**
+   Only fix the specified test; don't add extra tests along the way.

-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。
+4. **Don't Act Unilaterally**
+   When discovering other issues, don't modify them directly—raise and discuss first.

-### 测试协作最佳实践
+### Testing Collaboration Best Practices

-基于实际开发经验总结的重要协作原则：
+Important collaboration principles based on real development experience:

-#### 1. 失败处理策略
+#### 1. Failure Handling Strategy

-**核心原则**: 避免盲目重试，快速识别问题并寻求帮助。
+**Core Principle**: Avoid blind retries; quickly identify problems and seek help.

- **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
+- **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

 ```typescript
-//  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
+// ❌ Wrong approach: Keep blindly trying after consecutive failures
+// 3rd, 4th attempts still using similar methods to fix the same problem

-//  正确做法：失败1-2次后总结问题
+// ✅ Correct approach: Summarize after 1-2 failures
 /*
-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
+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
 */
 ```

-#### 2. 测试用例命名规范
+#### 2. Test Case Naming Conventions

-**核心原则**: 测试应该关注"行为"，而不是"实现细节"。
+**Core Principle**: Tests should focus on "behavior," not "implementation details."

- **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
+- **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

 ```typescript
-//  错误的测试命名
+// ❌ Poor test naming
 describe('User component coverage', () => {
  it('covers line 45-50 in getUserData', () => {
-    // 为了覆盖第45-50行而写的测试
+    // Test written just to cover lines 45-50
  });

  it('tests the else branch', () => {
-    // 仅为了测试某个分支而存在
+    // Exists only to test a specific branch
  });
 });

-//  正确的测试命名
+// ✅ Good test naming
 describe('<UserAvatar />', () => {
  it('should render fallback icon when image url is not provided', () => {
-    // 测试具体的业务场景，自然会覆盖相关代码分支
+    // Tests a specific business scenario, naturally covering relevant code branches
  });

  it('should display user initials when avatar image fails to load', () => {
-    // 描述用户行为和预期结果
+    // Describes user behavior and expected outcome
  });
 });
 ```

-**覆盖率提升的正确思路**:
+**The Right Approach to Improving Coverage**:

- 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"
+- 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

-#### 3. 测试组织结构
+#### 3. Test Organization Structure

-**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。
+**Core Principle**: Maintain a clear test hierarchy; avoid redundant top-level test blocks.

- **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
+- **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

 ```typescript
-//  错误的组织方式：创建过多顶级块
+// ❌ Poor organization: Too many top-level blocks
 describe('<UserProfile />', () => {
  it('should render user name', () => {});
 });

 describe('UserProfile new prop test', () => {
-  // 不必要的新块
+  // Unnecessary new block
  it('should handle email display', () => {});
 });

 describe('UserProfile edge cases', () => {
-  // 不必要的新块
+  // Unnecessary new block
  it('should handle missing avatar', () => {});
 });

-//  正确的组织方式：合并相关测试
+// ✅ Good organization: Merge related tests
 describe('<UserProfile />', () => {
  it('should render user name', () => {});

 ```

-**组织决策流程**:
+**Organization Decision Flow**:

-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`
+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`

-### 测试修复流程
+### Test Fixing Workflow

-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
+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

+## Test Fix Summary

-**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。
+**Root Cause**: The mock data format in the test didn't match the actual API response format, causing assertion failures.

-**修复方法**: 更新了测试文件中的 mock 数据结构，使其与最新的 API 响应格式保持一致。具体修改了 `user.test.ts` 中的 `mockUserData` 对象结构。
+**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`.
 ```

-## 测试编写最佳实践
+## Test Writing Best Practices

-### Mock 数据策略：追求"低成本的真实性"
+### Mock Data Strategy: Aim for "Low-Cost Authenticity"

-**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。
+**Core Principle**: Test data should default to authenticity; only simplify when it introduces "high testing costs."

-#### 什么是"高昂的测试成本"？
+#### What Are "High Testing Costs"?

-"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：
+"High cost" refers to introducing external dependencies in tests that make them slow, unstable, or complex:

- **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
+- **File I/O Operations**: Reading/writing disk files
+- **Network Requests**: HTTP calls, database connections
+- **System Calls**: Getting system time, environment variables, etc.

-#### 推荐做法：Mock 依赖，保留真实数据
+#### Recommended Approach: Mock Dependencies, Keep Real Data

 ```typescript
-//  好的做法：Mock I/O 操作，但使用真实的文件内容格式
+// ✅ Good approach: Mock I/O operations but use real file content formats
 describe('parseContentType', () => {
  beforeEach(() => {
-    // Mock 文件读取操作（避免真实 I/O）
+    // Mock file read operation (avoid real I/O)
    vi.spyOn(fs, 'readFileSync').mockImplementation((path) => {
-      // 但返回真实的文件内容格式
-      if (path.includes('.pdf')) return '%PDF-1.4\n%âãÏÓ'; // 真实 PDF 文件头
-      if (path.includes('.png')) return '\x89PNG\r\n\x1a\n'; // 真实 PNG 文件头
+      // But return real file content formats
+      if (path.includes('.pdf')) return '%PDF-1.4\n%âãÏÓ'; // Real PDF header

  vi.spyOn(URL, 'revokeObjectURL').mockImplementation(() => {});
 });
 ```

-**环境选择优先级**
+#### Environment Selection Priority

-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
+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

-**Mock方法对比**
+#### Mock Method Comparison

 ```typescript
-// ❌ 旧方法：直接操作global对象（类型问题）
+// ❌ Old method: Directly manipulating global object (type issues)
 global.Image = mockImage;
 global.URL = { ...global.URL, createObjectURL: mockFn };

-// ✅ 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
+// ✅ Modern method: Type-safe vi API
+vi.stubGlobal('Image', mockImage); // Completely replace global object
+vi.spyOn(URL, 'createObjectURL'); // Partial mock, preserve other functionality
 ```

-### 测试覆盖率原则：代码分支优于用例数量
+### Test Coverage Principles: Code Branches Over Test Quantity

-**核心原则**: 优先覆盖所有代码分支，而非编写大量重复用例
+**Core Principle**: Prioritize covering all code branches rather than writing many repetitive test cases.

 ```typescript
-// ❌ 过度测试：29个测试用例都验证相同分支
+// ❌ Over-testing: 29 test cases all validating the same branch
 describe('getImageDimensions', () => {
  it('should reject .txt files');
  it('should reject .pdf files');
-  // ... 25个类似测试，都走相同的验证分支
+  // ... 25 similar tests, all hitting the same validation branch
 });

-// ✅ 精简测试：4个核心用例覆盖所有分支
+// ✅ Lean testing: 4 core cases covering all branches
 describe('getImageDimensions', () => {
-  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
+  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
 });
 ```

-**分支覆盖策略**
+#### Branch Coverage Strategy

-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
+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

-**合理测试数量**
+#### Reasonable Test Counts

- 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
+- Simple utility functions: 2-5 tests
+- Complex business logic: 5-10 tests
+- Core security features: Add more as needed, but avoid duplicate paths

-### 错误处理测试：测试"行为"而非"文本"
+### Error Handling Tests: Test "Behavior" Not "Text"

-**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。
+**Core Principle**: Tests should verify that program behavior is predictable when errors occur, not verify error message text that may change.

-#### 推荐的错误测试方式
+#### Recommended Error Testing Approach

 ```typescript
-// ✅ 测试错误类型和属性
+// ✅ Test error types and properties

-### 疑难解答：警惕模块污染
+### Troubleshooting: Beware of Module Pollution

-**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：
+**Warning Signs**: When your tests exhibit these "mysterious" behaviors, suspect module pollution first:

- 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
+- 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

-#### 典型场景：动态 Mock 同一模块
+#### Typical Scenario: Dynamic Mocking of the Same Module

 ```typescript
-// ❌ 问题：动态Mock同一模块
+// ❌ Problem: Dynamic mocking of the same module
 it('dev mode', async () => {
  vi.doMock('./config', () => ({ isDev: true }));
-  const { getSettings } = await import('./service'); // 可能使用缓存
+  const { getSettings } = await import('./service'); // May use cache
 });

-// ✅ 解决：清除模块缓存
+// ✅ Solution: Clear module cache
 beforeEach(() => {
-  vi.resetModules(); // 确保每个测试都是干净环境
+  vi.resetModules(); // Ensure each test has a clean environment
 });
 ```

-**记住**: `vi.resetModules()` 是解决测试"灵异"失败的终极武器。
+**Remember**: `vi.resetModules()` is the ultimate weapon for resolving "mysterious" test failures.

-## 测试文件组织
+## Test File Organization

-### 文件命名约定
+### File Naming Convention

-`*.test.ts`, `*.test.tsx` (任意位置)
+`*.test.ts`, `*.test.tsx` (any location)

-### 测试文件组织风格
+### Test File Organization Style

-项目采用 **测试文件与源文件同目录** 的组织风格：
+The project uses a **co-located test files** organization style:

- 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`
+- Test files are placed in the same directory as the corresponding source files
+- Naming format: `originalFileName.test.ts` or `originalFileName.test.tsx`

-例如：
+Example:

 ```plaintext
 src/components/Button/
-├── index.tsx           # 源文件
-└── index.test.tsx      # 测试文件
+├── index.tsx           # Source file
+└── index.test.tsx      # Test file
 ```

- 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
+- 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

-## 测试调试技巧
+## Test Debugging Tips

-### 测试调试步骤
+### Test Debugging Steps

-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
+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

-### TypeScript 类型处理
+### TypeScript Type Handling

-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：
+In tests, you can relax TypeScript type checking to improve writing efficiency and readability:

-#### 推荐的类型放宽策略
+#### Recommended Type Relaxation Strategies

 ```typescript
-//  使用非空断言访问测试中确定存在的属性
+// Use non-null assertion to access properties you're certain exist in tests
 const result = await someFunction();
 expect(result!.data).toBeDefined();
 expect(result!.status).toBe('success');

-//  使用 any 类型简化复杂的 Mock 设置
+// Use any type to simplify complex mock setups
 const mockStream = new ReadableStream() as any;
 mockStream.toReadableStream = () => mockStream;

-//  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
+// Access private members
+await instance['getFromCache']('key'); // Bracket notation recommended
+await (instance as any).getFromCache('key'); // Avoid as any
 ```

-#### 适用场景
+#### Applicable Scenarios

- **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
+- **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

-#### 注意事项
+#### Important Notes

- **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
+- **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`

-### 检查最近修改记录
+### Checking Recent Modifications

-**核心原则**：测试突然失败时，优先检查最近的代码修改。
+**Core Principle**: When tests suddenly fail, first check recent code changes.

-#### 快速检查方法
+#### Quick Check Methods

 ```bash
-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
+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
 ```

-#### 常见原因与解决
+#### Common Causes and Solutions

- **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
+- **Latest commit introduced a bug** → Check and fix the implementation code
+- **Branch code is outdated** → `git rebase main` to sync with main branch

-## 特殊场景的测试
+## Special Testing Scenarios

-针对一些特殊场景的测试，需要阅读相关 rules：
+For special testing scenarios, refer to the related rules:

+- `electron-ipc-test.mdc` - Electron IPC Interface Testing Strategy
+- `db-model-test.mdc` - Database Model Testing Guide

-## 核心要点
+## Key Takeaways

- **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
+- **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

-# LobeChat Zustand Action 组织模式

-本文档详细说明了 LobeChat 项目中 Zustand Action 的组织方式、命名规范和实现模式，特别关注乐观更新与后端服务的集成。
+# LobeChat Zustand Action Patterns

-## Action 类型分层
+## Action Type Hierarchy

-LobeChat 的 Action 采用分层架构，明确区分不同职责：
+LobeChat Actions use a layered architecture with clear separation of responsibilities:

 ### 1. Public Actions
-对外暴露的主要接口，供 UI 组件调用：
- 命名：动词形式（`createTopic`, `sendMessage`, `updateTopicTitle`）
- 职责：参数验证、流程编排、调用 internal actions
- 示例：[src/store/chat/slices/topic/action.ts](mdc:src/store/chat/slices/topic/action.ts)
+
+Main interfaces exposed for UI component consumption:
+
+- Naming: Verb form (`createTopic`, `sendMessage`, `updateTopicTitle`)
+- Responsibilities: Parameter validation, flow orchestration, calling internal actions
+- Example: `src/store/chat/slices/topic/action.ts`

 ```typescript
-// Public Action 示例
+// Public Action example
 createTopic: async () => {
-  const { activeId, internal_createTopic } = get();
-  const messages = chatSelectors.activeBaseChats(get());
-  
-  if (messages.length === 0) return;
-  
-  const topicId = await internal_createTopic({
-    sessionId: activeId,
-    title: t('defaultTitle', { ns: 'topic' }),
-    messages: messages.map((m) => m.id),
-  });
-  
+  // ...
  return topicId;
 },
 ```

 ### 2. Internal Actions (`internal_*`)
-内部实现细节，处理核心业务逻辑：
- 命名：`internal_` 前缀 + 动词（`internal_createTopic`, `internal_updateMessageContent`）
- 职责：乐观更新、服务调用、错误处理、状态同步
- 不应该被 UI 组件直接调用
+
+Internal implementation details handling core business logic:
+
+- Naming: `internal_` prefix + verb (`internal_createTopic`, `internal_updateMessageContent`)
+- Responsibilities: Optimistic updates, service calls, error handling, state synchronization
+- Should not be called directly by UI components

 ```typescript
-// Internal Action 示例 - 乐观更新模式
+// Internal Action example - Optimistic update pattern
 internal_createTopic: async (params) => {
  const tmpId = Date.now().toString();
-  
-  // 1. 立即更新前端状态（乐观更新）
+
+  // 1. Immediately update frontend state (optimistic update)
  get().internal_dispatchTopic(
    { type: 'addTopic', value: { ...params, id: tmpId } },
    'internal_createTopic',
  );
  get().internal_updateTopicLoading(tmpId, true);
-  
-  // 2. 调用后端服务
+
+  // 2. Call backend service
  const topicId = await topicService.createTopic(params);
  get().internal_updateTopicLoading(tmpId, false);
-  
-  // 3. 刷新数据确保一致性
+
+  // 3. Refresh data to ensure consistency
  get().internal_updateTopicLoading(topicId, true);
  await get().refreshTopic();
  get().internal_updateTopicLoading(topicId, false);
-  
+
  return topicId;
 },
 ```

 ### 3. Dispatch Methods (`internal_dispatch*`)
-专门处理状态更新的方法：
- 命名：`internal_dispatch` + 实体名（`internal_dispatchTopic`, `internal_dispatchMessage`）
- 职责：调用 reducer、更新 Zustand store、处理状态对比
+
+Methods dedicated to handling state updates:
+
+- Naming: `internal_dispatch` + entity name (`internal_dispatchTopic`, `internal_dispatchMessage`)
+- Responsibilities: Calling reducers, updating Zustand store, handling state comparison

 ```typescript

-## 何时使用 Reducer 模式 vs. 简单 `set`
+## When to Use Reducer Pattern vs. Simple `set`

-### 使用 Reducer 模式的场景
+### Use Reducer Pattern When

-适用于复杂的数据结构管理，特别是：
- 管理对象列表或映射（如 `messagesMap`, `topicMaps`）
- 需要乐观更新的场景
- 状态转换逻辑复杂
- 需要类型安全的 action payload
+Suitable for complex data structure management, especially:
+
+- Managing object lists or maps (e.g., `messagesMap`, `topicMaps`)
+- Scenarios requiring optimistic updates
+- Complex state transition logic
+- Type-safe action payloads needed

 ```typescript

+// Reducer pattern example - Complex message state management
 export const messagesReducer = (state: ChatMessage[], payload: MessageDispatch): ChatMessage[] => {
  switch (payload.type) {
    case 'updateMessage': {

-## 乐观更新实现模式
+## Optimistic Update Implementation Patterns

-乐观更新是 LobeChat 中的核心模式，用于提供流畅的用户体验：
+Optimistic updates are a core pattern in LobeChat for providing smooth user experience:

-### 标准乐观更新流程
+### Standard Optimistic Update Flow

 ```typescript
-// 完整的乐观更新示例
+// Complete optimistic update example
 internal_updateMessageContent: async (id, content, extra) => {
  const { internal_dispatchMessage, refreshMessages } = get();

-  // 1. 立即更新前端状态（乐观更新）
+  // 1. Immediately update frontend state (optimistic update)
  internal_dispatchMessage({
    id,
    type: 'updateMessage',
    value: { content },
  });

-  // 2. 调用后端服务
+  // 2. Call backend service
  await messageService.updateMessage(id, {

-    // ...其他字段
+    // ...other fields
  });

-  // 3. 刷新确保数据一致性
+  // 3. Refresh to ensure data consistency
  await refreshMessages();
 },
 ```

-### 创建操作的乐观更新
+### Optimistic Update for Create Operations

 ```typescript
 internal_createMessage: async (message, context) => {
  const { internal_createTmpMessage, refreshMessages, internal_toggleMessageLoading } = get();
-

  let tempId = context?.tempMessageId;
  if (!tempId) {

-### 删除操作模式（不使用乐观更新）
+### Delete Operation Pattern (No Optimistic Update)

-删除操作通常不适合乐观更新，因为：
- 删除是破坏性操作，错误恢复复杂
- 用户对删除操作的即时反馈期望较低
- 删除失败时恢复原状态会造成困惑
+Delete operations typically don't suit optimistic updates because:
+
+- Deletion is destructive; error recovery is complex
+- Users have lower expectations for immediate feedback on deletions
+- Restoring state on deletion failure causes confusion

 ```typescript
-// 删除操作的标准模式 - 无乐观更新
+// Standard delete operation pattern - No optimistic update
 removeGenerationTopic: async (id: string) => {
  const { internal_removeGenerationTopic } = get();
  await internal_removeGenerationTopic(id);
 },

 internal_removeGenerationTopic: async (id: string) => {
-  // 1. 显示加载状态
+  // 1. Show loading state
  get().internal_updateGenerationTopicLoading(id, true);
-  
+
  try {
-    // 2. 直接调用后端服务
+    // 2. Directly call backend service
    await generationTopicService.deleteTopic(id);
-    
-    // 3. 刷新数据获取最新状态
+
+    // 3. Refresh data to get latest state
    await get().refreshGenerationTopics();
  } finally {
-    // 4. 确保清除加载状态（无论成功或失败）
+    // 4. Ensure loading state is cleared (whether success or failure)
    get().internal_updateGenerationTopicLoading(id, false);
  }
 },
 ```

-删除操作的特点：
- 直接调用服务，不预先更新状态
- 依赖 loading 状态提供用户反馈
- 操作完成后刷新整个列表确保一致性
- 使用 `try/finally` 确保 loading 状态总是被清理
+Delete operation characteristics:

-## 加载状态管理模式
+- Directly call service without pre-updating state
+- Rely on loading state for user feedback
+- Refresh entire list after operation to ensure consistency
+- Use `try/finally` to ensure loading state is always cleaned up

-LobeChat 使用统一的加载状态管理模式：
+## Loading State Management Pattern

-### 数组式加载状态
+LobeChat uses a unified loading state management pattern:
+
+### Array-based Loading State

 ```typescript
-// 在 initialState.ts 中定义
+// Define in initialState.ts
 export interface ChatMessageState {
-  messageLoadingIds: string[];      // 消息加载状态
-  messageEditingIds: string[];      // 消息编辑状态
-  chatLoadingIds: string[];         // 对话生成状态
+  messageEditingIds: string[]; // Message editing state
 }

-// 在 action 中管理
-internal_toggleMessageLoading: (loading, id) => {
-  set({
-    messageLoadingIds: toggleBooleanList(get().messageLoadingIds, id, loading),
-  }, false, `internal_toggleMessageLoading/${loading ? 'start' : 'end'}`);
-},
+// Manage in action
+{
+  toggleMessageEditing: (id, editing) => {
+    set(
+      { messageEditingIds: toggleBooleanList(get().messageEditingIds, id, editing) },
+      false,
+      'toggleMessageEditing',
+    );
+  };
+}
 ```

-### 统一的加载状态工具
+## SWR Integration Pattern
+
+LobeChat uses SWR for data fetching and cache management:
+
+### Hook-based Data Fetching

 ```typescript
-// 通用的加载状态切换工具
-internal_toggleLoadingArrays: (key, loading, id, action) => {
-  const abortControllerKey = `${key}AbortController`;
-  
-  if (loading) {
-    const abortController = new AbortController();
-    set({
-      [abortControllerKey]: abortController,
-      [key]: toggleBooleanList(get()[key] as string[], id!, loading),
-    }, false, action);
-    return abortController;
-  } else {
-    set({
-      [abortControllerKey]: undefined,
-      [key]: id ? toggleBooleanList(get()[key] as string[], id, loading) : [],
-    }, false, action);
-  }
-},
-```
-
-## SWR 集成模式
-
-LobeChat 使用 SWR 进行数据获取和缓存管理：
-
-### Hook 式数据获取
-
-```typescript
-// 在 action.ts 中定义 SWR hook

  useClientDataSWR<ChatMessage[]>(

-### 缓存失效和刷新
+### Cache Invalidation and Refresh

 ```typescript
-// 刷新数据的标准模式
+// Standard data refresh pattern

  await mutate([SWR_USE_FETCH_MESSAGES, get().activeId, get().activeTopicId]);
-},
-

 ```

-## 命名规范总结
+## Naming Convention Summary

-### Action 命名模式
- Public Actions: 动词形式，描述用户意图
+### Action Naming Patterns
+
+- Public Actions: Verb form, describing user intent
  - `createTopic`, `sendMessage`, `regenerateMessage`
- Internal Actions: `internal_` + 动词，描述内部操作
+- Internal Actions: `internal_` + verb, describing internal operation
  - `internal_createTopic`, `internal_updateMessageContent`
- Dispatch Methods: `internal_dispatch` + 实体名
+- Dispatch Methods: `internal_dispatch` + entity name
  - `internal_dispatchTopic`, `internal_dispatchMessage`
- Toggle Methods: `internal_toggle` + 状态名
+- Toggle Methods: `internal_toggle` + state name
  - `internal_toggleMessageLoading`, `internal_toggleChatLoading`

-### 状态命名模式
- ID 数组: `[entity]LoadingIds`, `[entity]EditingIds`
- 映射结构: `[entity]Maps`, `[entity]Map`
- 当前激活: `active[Entity]Id`
- 初始化标记: `[entity]sInit`
+### State Naming Patterns

-## 最佳实践
+- ID arrays: `[entity]LoadingIds`, `[entity]EditingIds`
+- Map structures: `[entity]Maps`, `[entity]Map`
+- Currently active: `active[Entity]Id`
+- Initialization flags: `[entity]sInit`

-1. 合理使用乐观更新：
-   - ✅ 适用：创建、更新操作（用户交互频繁）
-   - ❌ 避免：删除操作（破坏性操作，错误恢复复杂）
-2. 加载状态管理：使用统一的加载状态数组管理并发操作
-3. 类型安全：为所有 action payload 定义 TypeScript 接口
-4. SWR 集成：使用 SWR 管理数据获取和缓存失效
-5. AbortController：为长时间运行的操作提供取消能力
-6. 操作模式选择：
-   - 创建/更新：乐观更新 + 最终一致性
-   - 删除：加载状态 + 服务调用 + 数据刷新
+## Best Practices

-这套 Action 组织模式确保了代码的一致性、可维护性，并提供了优秀的用户体验。
+1. Use optimistic updates appropriately:
+   - ✅ Suitable: Create, update operations (frequent user interaction)
+   - ❌ Avoid: Delete operations (destructive, complex error recovery)
+2. Loading state management: Use unified loading state arrays to manage concurrent operations
+3. Type safety: Define TypeScript interfaces for all action payloads
+4. SWR integration: Use SWR to manage data fetching and cache invalidation
+5. AbortController: Provide cancellation capability for long-running operations
+6. Operation mode selection:
+   - Create/Update: Optimistic update + eventual consistency
+   - Delete: Loading state + service call + data refresh
+
+This Action organization pattern ensures code consistency, maintainability, and provides excellent user experience.

+
+## 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)
+
+- `server-cache-react` - Use React.cache() for per-request deduplication
+- `server-cache-lru` - Use LRU cache for cross-request caching
+- `server-serialization` - Minimize data passed to client components
+- `server-parallel-fetching` - Restructure components to parallelize fetches
+- `server-after-nonblocking` - Use after() for non-blocking operations
+
+### 4. Client-Side Data Fetching (MEDIUM-HIGH)
+
+- `client-swr-dedup` - Use SWR for automatic request deduplication
+- `client-event-listeners` - Deduplicate global event listeners
+
+### 5. Re-render Optimization (MEDIUM)
+
+- `rerender-defer-reads` - Don't subscribe to state only used in callbacks
+- `rerender-memo` - Extract expensive work into memoized components
+- `rerender-dependencies` - Use primitive dependencies in effects
+- `rerender-derived-state` - Subscribe to derived booleans, not raw values
+- `rerender-functional-setstate` - Use functional setState for stable callbacks
+- `rerender-lazy-state-init` - Pass function to useState for expensive values
+- `rerender-transitions` - Use startTransition for non-urgent updates
+
+### 6. Rendering Performance (MEDIUM)
+
+- `rendering-animate-svg-wrapper` - Animate div wrapper, not SVG element
+- `rendering-content-visibility` - Use content-visibility for long lists
+- `rendering-hoist-jsx` - Extract static JSX outside components
+- `rendering-svg-precision` - Reduce SVG coordinate precision
+- `rendering-hydration-no-flicker` - Use inline script for client-only data
+- `rendering-activity` - Use Activity component for show/hide
+- `rendering-conditional-render` - Use ternary, not && for conditionals
+
+### 7. JavaScript Performance (LOW-MEDIUM)
+
+- `js-batch-dom-css` - Group CSS changes via classes or cssText
+- `js-index-maps` - Build Map for repeated lookups
+- `js-cache-property-access` - Cache object properties in loops
+- `js-cache-function-results` - Cache function results in module-level Map
+- `js-cache-storage` - Cache localStorage/sessionStorage reads
+- `js-combine-iterations` - Combine multiple filter/map into one loop
+- `js-length-check-first` - Check array length before expensive comparison
+- `js-early-exit` - Return early from functions
+- `js-hoist-regexp` - Hoist RegExp creation outside loops
+- `js-min-max-loop` - Use loop for min/max instead of sort
+- `js-set-map-lookups` - Use Set/Map for O(1) lookups
+- `js-tosorted-immutable` - Use toSorted() for immutability
+
+### 8. Advanced Patterns (LOW)
+
+- `advanced-event-handler-refs` - Store event handlers in refs
+- `advanced-use-latest` - useLatest for stable callback refs

+## 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.

+
+## 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.

+title: Avoid Barrel File Imports
+impact: CRITICAL
+impactDescription: 200-800ms import cost, slow builds
+tags: bundle, imports, tree-shaking, barrel-files, performance
+---
+
+## 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.
