+description: Refactor high-complexity React components in Dify frontend. Use when `pnpm analyze-component --json` shows complexity > 50 or lineCount > 300, when the user asks for code splitting, hook extraction, or complexity reduction, or when `pnpm analyze-component` warns to refactor before testing; avoid for simple/well-structured components, third-party wrappers, or when the user explicitly wants testing without refactoring.

+
+# Dify Component Refactoring Skill
+
+Refactor high-complexity React components in the Dify frontend codebase with the patterns and workflow below.
+
+> **Complexity Threshold**: Components with complexity > 50 (measured by `pnpm analyze-component`) should be refactored before testing.
+
+## Quick Reference
+
+### Commands (run from `web/`)
+
+Use paths relative to `web/` (e.g., `app/components/...`).
+Use `refactor-component` for refactoring prompts and `analyze-component` for testing prompts and metrics.
+
+```bash
+cd web
+
+# Generate refactoring prompt
+pnpm refactor-component <path>
+
+# Output refactoring analysis as JSON
+pnpm refactor-component <path> --json
+
+# Generate testing prompt (after refactoring)
+pnpm analyze-component <path>
+
+# Output testing analysis as JSON
+pnpm analyze-component <path> --json
+```
+
+### Complexity Analysis
+
+```bash
+# Analyze component complexity
+pnpm analyze-component <path> --json
+
+# Key metrics to check:
+# - complexity: normalized score 0-100 (target < 50)
+# - maxComplexity: highest single function complexity
+# - lineCount: total lines (target < 300)
+```
+
+### Complexity Score Interpretation
+
+| Score | Level | Action |
+|-------|-------|--------|
+| 0-25 | 🟢 Simple | Ready for testing |
+| 26-50 | 🟡 Medium | Consider minor refactoring |
+| 51-75 | 🟠 Complex | **Refactor before testing** |
+| 76-100 | 🔴 Very Complex | **Must refactor** |
+
+## Core Refactoring Patterns
+
+### Pattern 1: Extract Custom Hooks
+
+**When**: Component has complex state management, multiple `useState`/`useEffect`, or business logic mixed with UI.
+
+**Dify Convention**: Place hooks in a `hooks/` subdirectory or alongside the component as `use-<feature>.ts`.
+
+```typescript
+// ❌ Before: Complex state logic in component
+const Configuration: FC = () => {
+  const [modelConfig, setModelConfig] = useState<ModelConfig>(...)
+  const [datasetConfigs, setDatasetConfigs] = useState<DatasetConfigs>(...)
+  const [completionParams, setCompletionParams] = useState<FormValue>({})
+  
+  // 50+ lines of state management logic...
+  
+  return <div>...</div>
+}
+
+// ✅ After: Extract to custom hook
+// hooks/use-model-config.ts
+export const useModelConfig = (appId: string) => {
+  const [modelConfig, setModelConfig] = useState<ModelConfig>(...)
+  const [completionParams, setCompletionParams] = useState<FormValue>({})
+  
+  // Related state management logic here
+  
+  return { modelConfig, setModelConfig, completionParams, setCompletionParams }
+}
+
+// Component becomes cleaner
+const Configuration: FC = () => {
+  const { modelConfig, setModelConfig } = useModelConfig(appId)
+  return <div>...</div>
+}
+```
+
+**Dify Examples**:
+- `web/app/components/app/configuration/hooks/use-advanced-prompt-config.ts`
+- `web/app/components/app/configuration/debug/hooks.tsx`
+- `web/app/components/workflow/hooks/use-workflow.ts`
+
+### Pattern 2: Extract Sub-Components
+
+**When**: Single component has multiple UI sections, conditional rendering blocks, or repeated patterns.
+
+**Dify Convention**: Place sub-components in subdirectories or as separate files in the same directory.
+
+```typescript
+// ❌ Before: Monolithic JSX with multiple sections
+const AppInfo = () => {
+  return (
+    <div>
+      {/* 100 lines of header UI */}
+      {/* 100 lines of operations UI */}
+      {/* 100 lines of modals */}
+    </div>
+  )
+}
+
+// ✅ After: Split into focused components
+// app-info/
+//   ├── index.tsx           (orchestration only)
+//   ├── app-header.tsx      (header UI)
+//   ├── app-operations.tsx  (operations UI)
+//   └── app-modals.tsx      (modal management)
+
+const AppInfo = () => {
+  const { showModal, setShowModal } = useAppInfoModals()
+  
+  return (
+    <div>
+      <AppHeader appDetail={appDetail} />
+      <AppOperations onAction={handleAction} />
+      <AppModals show={showModal} onClose={() => setShowModal(null)} />
+    </div>
+  )
+}
+```
+
+**Dify Examples**:
+- `web/app/components/app/configuration/` directory structure
+- `web/app/components/workflow/nodes/` per-node organization
+
+### Pattern 3: Simplify Conditional Logic
+
+**When**: Deep nesting (> 3 levels), complex ternaries, or multiple `if/else` chains.
+
+```typescript
+// ❌ Before: Deeply nested conditionals
+const Template = useMemo(() => {
+  if (appDetail?.mode === AppModeEnum.CHAT) {
+    switch (locale) {
+      case LanguagesSupported[1]:
+        return <TemplateChatZh />
+      case LanguagesSupported[7]:
+        return <TemplateChatJa />
+      default:
+        return <TemplateChatEn />
+    }
+  }
+  if (appDetail?.mode === AppModeEnum.ADVANCED_CHAT) {
+    // Another 15 lines...
+  }
+  // More conditions...
+}, [appDetail, locale])
+
+// ✅ After: Use lookup tables + early returns
+const TEMPLATE_MAP = {
+  [AppModeEnum.CHAT]: {
+    [LanguagesSupported[1]]: TemplateChatZh,
+    [LanguagesSupported[7]]: TemplateChatJa,
+    default: TemplateChatEn,
+  },
+  [AppModeEnum.ADVANCED_CHAT]: {
+    [LanguagesSupported[1]]: TemplateAdvancedChatZh,
+    // ...
+  },
+}
+
+const Template = useMemo(() => {
+  const modeTemplates = TEMPLATE_MAP[appDetail?.mode]
+  if (!modeTemplates) return null
+  
+  const TemplateComponent = modeTemplates[locale] || modeTemplates.default
+  return <TemplateComponent appDetail={appDetail} />
+}, [appDetail, locale])
+```
+
+### Pattern 4: Extract API/Data Logic
+
+**When**: Component directly handles API calls, data transformation, or complex async operations.
+
+**Dify Convention**: Use `@tanstack/react-query` hooks from `web/service/use-*.ts` or create custom data hooks.
+
+```typescript
+// ❌ Before: API logic in component
+const MCPServiceCard = () => {
+  const [basicAppConfig, setBasicAppConfig] = useState({})
+  
+  useEffect(() => {
+    if (isBasicApp && appId) {
+      (async () => {
+        const res = await fetchAppDetail({ url: '/apps', id: appId })
+        setBasicAppConfig(res?.model_config || {})
+      })()
+    }
+  }, [appId, isBasicApp])
+  
+  // More API-related logic...
+}
+
+// ✅ After: Extract to data hook using React Query
+// use-app-config.ts
+import { useQuery } from '@tanstack/react-query'
+import { get } from '@/service/base'
+
+const NAME_SPACE = 'appConfig'
+
+export const useAppConfig = (appId: string, isBasicApp: boolean) => {
+  return useQuery({
+    enabled: isBasicApp && !!appId,
+    queryKey: [NAME_SPACE, 'detail', appId],
+    queryFn: () => get<AppDetailResponse>(`/apps/${appId}`),
+    select: data => data?.model_config || {},
+  })
+}
+
+// Component becomes cleaner
+const MCPServiceCard = () => {
+  const { data: config, isLoading } = useAppConfig(appId, isBasicApp)
+  // UI only
+}
+```
+
+**React Query Best Practices in Dify**:
+- Define `NAME_SPACE` for query key organization
+- Use `enabled` option for conditional fetching
+- Use `select` for data transformation
+- Export invalidation hooks: `useInvalidXxx`
+
+**Dify Examples**:
+- `web/service/use-workflow.ts`
+- `web/service/use-common.ts`
+- `web/service/knowledge/use-dataset.ts`
+- `web/service/knowledge/use-document.ts`
+
+### Pattern 5: Extract Modal/Dialog Management
+
+**When**: Component manages multiple modals with complex open/close states.
+
+**Dify Convention**: Modals should be extracted with their state management.
+
+```typescript
+// ❌ Before: Multiple modal states in component
+const AppInfo = () => {
+  const [showEditModal, setShowEditModal] = useState(false)
+  const [showDuplicateModal, setShowDuplicateModal] = useState(false)
+  const [showConfirmDelete, setShowConfirmDelete] = useState(false)
+  const [showSwitchModal, setShowSwitchModal] = useState(false)
+  const [showImportDSLModal, setShowImportDSLModal] = useState(false)
+  // 5+ more modal states...
+}
+
+// ✅ After: Extract to modal management hook
+type ModalType = 'edit' | 'duplicate' | 'delete' | 'switch' | 'import' | null
+
+const useAppInfoModals = () => {
+  const [activeModal, setActiveModal] = useState<ModalType>(null)
+  
+  const openModal = useCallback((type: ModalType) => setActiveModal(type), [])
+  const closeModal = useCallback(() => setActiveModal(null), [])
+  
+  return {
+    activeModal,
+    openModal,
+    closeModal,
+    isOpen: (type: ModalType) => activeModal === type,
+  }
+}
+```
+
+### Pattern 6: Extract Form Logic
+
+**When**: Complex form validation, submission handling, or field transformation.
+
+**Dify Convention**: Use `@tanstack/react-form` patterns from `web/app/components/base/form/`.
+
+```typescript
+// ✅ Use existing form infrastructure
+import { useAppForm } from '@/app/components/base/form'
+
+const ConfigForm = () => {
+  const form = useAppForm({
+    defaultValues: { name: '', description: '' },
+    onSubmit: handleSubmit,
+  })
+  
+  return <form.Provider>...</form.Provider>
+}
+```
+
+## Dify-Specific Refactoring Guidelines
+
+### 1. Context Provider Extraction
+
+**When**: Component provides complex context values with multiple states.
+
+```typescript
+// ❌ Before: Large context value object
+const value = {
+  appId, isAPIKeySet, isTrailFinished, mode, modelModeType,
+  promptMode, isAdvancedMode, isAgent, isOpenAI, isFunctionCall,
+  // 50+ more properties...
+}
+return <ConfigContext.Provider value={value}>...</ConfigContext.Provider>
+
+// ✅ After: Split into domain-specific contexts
+<ModelConfigProvider value={modelConfigValue}>
+  <DatasetConfigProvider value={datasetConfigValue}>
+    <UIConfigProvider value={uiConfigValue}>
+      {children}
+    </UIConfigProvider>
+  </DatasetConfigProvider>
+</ModelConfigProvider>
+```
+
+**Dify Reference**: `web/context/` directory structure
+
+### 2. Workflow Node Components
+
+**When**: Refactoring workflow node components (`web/app/components/workflow/nodes/`).
+
+**Conventions**:
+- Keep node logic in `use-interactions.ts`
+- Extract panel UI to separate files
+- Use `_base` components for common patterns
+
+```
+nodes/<node-type>/
+  ├── index.tsx              # Node registration
+  ├── node.tsx               # Node visual component
+  ├── panel.tsx              # Configuration panel
+  ├── use-interactions.ts    # Node-specific hooks
+  └── types.ts               # Type definitions
+```
+
+### 3. Configuration Components
+
+**When**: Refactoring app configuration components.
+
+**Conventions**:
+- Separate config sections into subdirectories
+- Use existing patterns from `web/app/components/app/configuration/`
+- Keep feature toggles in dedicated components
+
+### 4. Tool/Plugin Components
+
+**When**: Refactoring tool-related components (`web/app/components/tools/`).
+
+**Conventions**:
+- Follow existing modal patterns
+- Use service hooks from `web/service/use-tools.ts`
+- Keep provider-specific logic isolated
+
+## Refactoring Workflow
+
+### Step 1: Generate Refactoring Prompt
+
+```bash
+pnpm refactor-component <path>
+```
+
+This command will:
+- Analyze component complexity and features
+- Identify specific refactoring actions needed
+- Generate a prompt for AI assistant (auto-copied to clipboard on macOS)
+- Provide detailed requirements based on detected patterns
+
+### Step 2: Analyze Details
+
+```bash
+pnpm analyze-component <path> --json
+```
+
+Identify:
+- Total complexity score
+- Max function complexity
+- Line count
+- Features detected (state, effects, API, etc.)
+
+### Step 3: Plan
+
+Create a refactoring plan based on detected features:
+
+| Detected Feature | Refactoring Action |
+|------------------|-------------------|
+| `hasState: true` + `hasEffects: true` | Extract custom hook |
+| `hasAPI: true` | Extract data/service hook |
+| `hasEvents: true` (many) | Extract event handlers |
+| `lineCount > 300` | Split into sub-components |
+| `maxComplexity > 50` | Simplify conditional logic |
+
+### Step 4: Execute Incrementally
+
+1. **Extract one piece at a time**
+2. **Run lint, type-check, and tests after each extraction**
+3. **Verify functionality before next step**
+
+```
+For each extraction:
+  ┌────────────────────────────────────────┐
+  │ 1. Extract code                        │
+  │ 2. Run: pnpm lint:fix                  │
+  │ 3. Run: pnpm type-check:tsgo           │
+  │ 4. Run: pnpm test                      │
+  │ 5. Test functionality manually         │
+  │ 6. PASS? → Next extraction             │
+  │    FAIL? → Fix before continuing       │
+  └────────────────────────────────────────┘
+```
+
+### Step 5: Verify
+
+After refactoring:
+
+```bash
+# Re-run refactor command to verify improvements
+pnpm refactor-component <path>
+
+# If complexity < 25 and lines < 200, you'll see:
+# ✅ COMPONENT IS WELL-STRUCTURED
+
+# For detailed metrics:
+pnpm analyze-component <path> --json
+
+# Target metrics:
+# - complexity < 50
+# - lineCount < 300
+# - maxComplexity < 30
+```
+
+## Common Mistakes to Avoid
+
+### ❌ Over-Engineering
+
+```typescript
+// ❌ Too many tiny hooks
+const useButtonText = () => useState('Click')
+const useButtonDisabled = () => useState(false)
+const useButtonLoading = () => useState(false)
+
+// ✅ Cohesive hook with related state
+const useButtonState = () => {
+  const [text, setText] = useState('Click')
+  const [disabled, setDisabled] = useState(false)
+  const [loading, setLoading] = useState(false)
+  return { text, setText, disabled, setDisabled, loading, setLoading }
+}
+```
+
+### ❌ Breaking Existing Patterns
+
+- Follow existing directory structures
+- Maintain naming conventions
+- Preserve export patterns for compatibility
+
+### ❌ Premature Abstraction
+
+- Only extract when there's clear complexity benefit
+- Don't create abstractions for single-use code
+- Keep refactored code in the same domain area

+# Complexity Reduction Patterns
+
+This document provides patterns for reducing cognitive complexity in Dify React components.
+
+## Understanding Complexity
+
+### SonarJS Cognitive Complexity
+
+The `pnpm analyze-component` tool uses SonarJS cognitive complexity metrics:
+
+- **Total Complexity**: Sum of all functions' complexity in the file
+- **Max Complexity**: Highest single function complexity
+
+### What Increases Complexity
+
+| Pattern | Complexity Impact |
+|---------|-------------------|
+| `if/else` | +1 per branch |
+| Nested conditions | +1 per nesting level |
+| `switch/case` | +1 per case |
+| `for/while/do` | +1 per loop |
+| `&&`/`||` chains | +1 per operator |
+| Nested callbacks | +1 per nesting level |
+| `try/catch` | +1 per catch |
+| Ternary expressions | +1 per nesting |
+
+## Pattern 1: Replace Conditionals with Lookup Tables
+
+**Before** (complexity: ~15):
+
+```typescript
+const Template = useMemo(() => {
+  if (appDetail?.mode === AppModeEnum.CHAT) {
+    switch (locale) {
+      case LanguagesSupported[1]:
+        return <TemplateChatZh appDetail={appDetail} />
+      case LanguagesSupported[7]:
+        return <TemplateChatJa appDetail={appDetail} />
+      default:
+        return <TemplateChatEn appDetail={appDetail} />
+    }
+  }
+  if (appDetail?.mode === AppModeEnum.ADVANCED_CHAT) {
+    switch (locale) {
+      case LanguagesSupported[1]:
+        return <TemplateAdvancedChatZh appDetail={appDetail} />
+      case LanguagesSupported[7]:
+        return <TemplateAdvancedChatJa appDetail={appDetail} />
+      default:
+        return <TemplateAdvancedChatEn appDetail={appDetail} />
+    }
+  }
+  if (appDetail?.mode === AppModeEnum.WORKFLOW) {
+    // Similar pattern...
+  }
+  return null
+}, [appDetail, locale])
+```
+
+**After** (complexity: ~3):
+
+```typescript
+// Define lookup table outside component
+const TEMPLATE_MAP: Record<AppModeEnum, Record<string, FC<TemplateProps>>> = {
+  [AppModeEnum.CHAT]: {
+    [LanguagesSupported[1]]: TemplateChatZh,
+    [LanguagesSupported[7]]: TemplateChatJa,
+    default: TemplateChatEn,
+  },
+  [AppModeEnum.ADVANCED_CHAT]: {
+    [LanguagesSupported[1]]: TemplateAdvancedChatZh,
+    [LanguagesSupported[7]]: TemplateAdvancedChatJa,
+    default: TemplateAdvancedChatEn,
+  },
+  [AppModeEnum.WORKFLOW]: {
+    [LanguagesSupported[1]]: TemplateWorkflowZh,
+    [LanguagesSupported[7]]: TemplateWorkflowJa,
+    default: TemplateWorkflowEn,
+  },
+  // ...
+}
+
+// Clean component logic
+const Template = useMemo(() => {
+  if (!appDetail?.mode) return null
+  
+  const templates = TEMPLATE_MAP[appDetail.mode]
+  if (!templates) return null
+  
+  const TemplateComponent = templates[locale] ?? templates.default
+  return <TemplateComponent appDetail={appDetail} />
+}, [appDetail, locale])
+```
+
+## Pattern 2: Use Early Returns
+
+**Before** (complexity: ~10):
+
+```typescript
+const handleSubmit = () => {
+  if (isValid) {
+    if (hasChanges) {
+      if (isConnected) {
+        submitData()
+      } else {
+        showConnectionError()
+      }
+    } else {
+      showNoChangesMessage()
+    }
+  } else {
+    showValidationError()
+  }
+}
+```
+
+**After** (complexity: ~4):
+
+```typescript
+const handleSubmit = () => {
+  if (!isValid) {
+    showValidationError()
+    return
+  }
+  
+  if (!hasChanges) {
+    showNoChangesMessage()
+    return
+  }
+  
+  if (!isConnected) {
+    showConnectionError()
+    return
+  }
+  
+  submitData()
+}
+```
+
+## Pattern 3: Extract Complex Conditions
+
+**Before** (complexity: high):
+
+```typescript
+const canPublish = (() => {
+  if (mode !== AppModeEnum.COMPLETION) {
+    if (!isAdvancedMode)
+      return true
+
+    if (modelModeType === ModelModeType.completion) {
+      if (!hasSetBlockStatus.history || !hasSetBlockStatus.query)
+        return false
+      return true
+    }
+    return true
+  }
+  return !promptEmpty
+})()
+```
+
+**After** (complexity: lower):
+
+```typescript
+// Extract to named functions
+const canPublishInCompletionMode = () => !promptEmpty
+
+const canPublishInChatMode = () => {
+  if (!isAdvancedMode) return true
+  if (modelModeType !== ModelModeType.completion) return true
+  return hasSetBlockStatus.history && hasSetBlockStatus.query
+}
+
+// Clean main logic
+const canPublish = mode === AppModeEnum.COMPLETION
+  ? canPublishInCompletionMode()
+  : canPublishInChatMode()
+```
+
+## Pattern 4: Replace Chained Ternaries
+
+**Before** (complexity: ~5):
+
+```typescript
+const statusText = serverActivated
+  ? t('status.running')
+  : serverPublished
+    ? t('status.inactive')
+    : appUnpublished
+      ? t('status.unpublished')
+      : t('status.notConfigured')
+```
+
+**After** (complexity: ~2):
+
+```typescript
+const getStatusText = () => {
+  if (serverActivated) return t('status.running')
+  if (serverPublished) return t('status.inactive')
+  if (appUnpublished) return t('status.unpublished')
+  return t('status.notConfigured')
+}
+
+const statusText = getStatusText()
+```
+
+Or use lookup:
+
+```typescript
+const STATUS_TEXT_MAP = {
+  running: 'status.running',
+  inactive: 'status.inactive',
+  unpublished: 'status.unpublished',
+  notConfigured: 'status.notConfigured',
+} as const
+
+const getStatusKey = (): keyof typeof STATUS_TEXT_MAP => {
+  if (serverActivated) return 'running'
+  if (serverPublished) return 'inactive'
+  if (appUnpublished) return 'unpublished'
+  return 'notConfigured'
+}
+
+const statusText = t(STATUS_TEXT_MAP[getStatusKey()])
+```
+
+## Pattern 5: Flatten Nested Loops
+
+**Before** (complexity: high):
+
+```typescript
+const processData = (items: Item[]) => {
+  const results: ProcessedItem[] = []
+  
+  for (const item of items) {
+    if (item.isValid) {
+      for (const child of item.children) {
+        if (child.isActive) {
+          for (const prop of child.properties) {
+            if (prop.value !== null) {
+              results.push({
+                itemId: item.id,
+                childId: child.id,
+                propValue: prop.value,
+              })
+            }
+          }
+        }
+      }
+    }
+  }
+  
+  return results
+}
+```
+
+**After** (complexity: lower):
+
+```typescript
+// Use functional approach
+const processData = (items: Item[]) => {
+  return items
+    .filter(item => item.isValid)
+    .flatMap(item =>
+      item.children
+        .filter(child => child.isActive)
+        .flatMap(child =>
+          child.properties
+            .filter(prop => prop.value !== null)
+            .map(prop => ({
+              itemId: item.id,
+              childId: child.id,
+              propValue: prop.value,
+            }))
+        )
+    )
+}
+```
+
+## Pattern 6: Extract Event Handler Logic

+**Before** (complexity: high in component):
+
+```typescript
+const Component = () => {
+  const handleSelect = (data: DataSet[]) => {
+    if (isEqual(data.map(item => item.id), dataSets.map(item => item.id))) {
+      hideSelectDataSet()
+      return
+    }
+
+    formattingChangedDispatcher()
+    let newDatasets = data
+    if (data.find(item => !item.name)) {
+      const newSelected = produce(data, (draft) => {
+        data.forEach((item, index) => {
+          if (!item.name) {
+            const newItem = dataSets.find(i => i.id === item.id)
+            if (newItem)
+              draft[index] = newItem
+          }
+        })
+      })
+      setDataSets(newSelected)
+      newDatasets = newSelected
+    }
+    else {
+      setDataSets(data)
+    }
+    hideSelectDataSet()
+    
+    // 40 more lines of logic...
+  }
+  
+  return <div>...</div>
+}
+```
+
+**After** (complexity: lower):
+
+```typescript
+// Extract to hook or utility
+const useDatasetSelection = (dataSets: DataSet[], setDataSets: SetState<DataSet[]>) => {
+  const normalizeSelection = (data: DataSet[]) => {
+    const hasUnloadedItem = data.some(item => !item.name)
+    if (!hasUnloadedItem) return data
+    
+    return produce(data, (draft) => {
+      data.forEach((item, index) => {
+        if (!item.name) {
+          const existing = dataSets.find(i => i.id === item.id)
+          if (existing) draft[index] = existing
+        }
+      })
+    })
+  }
+  
+  const hasSelectionChanged = (newData: DataSet[]) => {
+    return !isEqual(
+      newData.map(item => item.id),
+      dataSets.map(item => item.id)
+    )
+  }
+  
+  return { normalizeSelection, hasSelectionChanged }
+}
+
+// Component becomes cleaner
+const Component = () => {
+  const { normalizeSelection, hasSelectionChanged } = useDatasetSelection(dataSets, setDataSets)
+  
+  const handleSelect = (data: DataSet[]) => {
+    if (!hasSelectionChanged(data)) {
+      hideSelectDataSet()
+      return
+    }
+    
+    formattingChangedDispatcher()
+    const normalized = normalizeSelection(data)
+    setDataSets(normalized)
+    hideSelectDataSet()
+  }
+  
+  return <div>...</div>
+}
+```
+
+## Pattern 7: Reduce Boolean Logic Complexity
+
+**Before** (complexity: ~8):
+
+```typescript
+const toggleDisabled = hasInsufficientPermissions
+  || appUnpublished
+  || missingStartNode
+  || triggerModeDisabled
+  || (isAdvancedApp && !currentWorkflow?.graph)
+  || (isBasicApp && !basicAppConfig.updated_at)
+```
+
+**After** (complexity: ~3):
+
+```typescript
+// Extract meaningful boolean functions
+const isAppReady = () => {
+  if (isAdvancedApp) return !!currentWorkflow?.graph
+  return !!basicAppConfig.updated_at
+}
+
+const hasRequiredPermissions = () => {
+  return isCurrentWorkspaceEditor && !hasInsufficientPermissions
+}
+
+const canToggle = () => {
+  if (!hasRequiredPermissions()) return false
+  if (!isAppReady()) return false
+  if (missingStartNode) return false
+  if (triggerModeDisabled) return false
+  return true
+}
+
+const toggleDisabled = !canToggle()
+```
+
+## Pattern 8: Simplify useMemo/useCallback Dependencies
+
+**Before** (complexity: multiple recalculations):
+
+```typescript
+const payload = useMemo(() => {
+  let parameters: Parameter[] = []
+  let outputParameters: OutputParameter[] = []
+
+  if (!published) {
+    parameters = (inputs || []).map((item) => ({
+      name: item.variable,
+      description: '',
+      form: 'llm',
+      required: item.required,
+      type: item.type,
+    }))
+    outputParameters = (outputs || []).map((item) => ({
+      name: item.variable,
+      description: '',
+      type: item.value_type,
+    }))
+  }
+  else if (detail && detail.tool) {
+    parameters = (inputs || []).map((item) => ({
+      // Complex transformation...
+    }))
+    outputParameters = (outputs || []).map((item) => ({
+      // Complex transformation...
+    }))
+  }
+  
+  return {
+    icon: detail?.icon || icon,
+    label: detail?.label || name,
+    // ...more fields
+  }
+}, [detail, published, workflowAppId, icon, name, description, inputs, outputs])
+```
+
+**After** (complexity: separated concerns):
+
+```typescript
+// Separate transformations
+const useParameterTransform = (inputs: InputVar[], detail?: ToolDetail, published?: boolean) => {
+  return useMemo(() => {
+    if (!published) {
+      return inputs.map(item => ({
+        name: item.variable,
+        description: '',
+        form: 'llm',
+        required: item.required,
+        type: item.type,
+      }))
+    }
+    
+    if (!detail?.tool) return []
+    
+    return inputs.map(item => ({
+      name: item.variable,
+      required: item.required,
+      type: item.type === 'paragraph' ? 'string' : item.type,
+      description: detail.tool.parameters.find(p => p.name === item.variable)?.llm_description || '',
+      form: detail.tool.parameters.find(p => p.name === item.variable)?.form || 'llm',
+    }))
+  }, [inputs, detail, published])
+}
+
+// Component uses hook
+const parameters = useParameterTransform(inputs, detail, published)
+const outputParameters = useOutputTransform(outputs, detail, published)
+
+const payload = useMemo(() => ({
+  icon: detail?.icon || icon,
+  label: detail?.label || name,
+  parameters,
+  outputParameters,
+  // ...
+}), [detail, icon, name, parameters, outputParameters])
+```

+# Component Splitting Patterns
+
+This document provides detailed guidance on splitting large components into smaller, focused components in Dify.
+
+## When to Split Components
+
+Split a component when you identify:
+
+1. **Multiple UI sections** - Distinct visual areas with minimal coupling that can be composed independently
+1. **Conditional rendering blocks** - Large `{condition && <JSX />}` blocks
+1. **Repeated patterns** - Similar UI structures used multiple times
+1. **300+ lines** - Component exceeds manageable size
+1. **Modal clusters** - Multiple modals rendered in one component
+
+## Splitting Strategies
+
+### Strategy 1: Section-Based Splitting
+
+Identify visual sections and extract each as a component.
+
+```typescript
+// ❌ Before: Monolithic component (500+ lines)
+const ConfigurationPage = () => {
+  return (
+    <div>
+      {/* Header Section - 50 lines */}
+      <div className="header">
+        <h1>{t('configuration.title')}</h1>
+        <div className="actions">
+          {isAdvancedMode && <Badge>Advanced</Badge>}
+          <ModelParameterModal ... />
+          <AppPublisher ... />
+        </div>
+      </div>
+      
+      {/* Config Section - 200 lines */}
+      <div className="config">
+        <Config />
+      </div>
+      
+      {/* Debug Section - 150 lines */}
+      <div className="debug">
+        <Debug ... />
+      </div>
+      
+      {/* Modals Section - 100 lines */}
+      {showSelectDataSet && <SelectDataSet ... />}
+      {showHistoryModal && <EditHistoryModal ... />}
+      {showUseGPT4Confirm && <Confirm ... />}
+    </div>
+  )
+}
+
+// ✅ After: Split into focused components
+// configuration/
+//   ├── index.tsx              (orchestration)
+//   ├── configuration-header.tsx
+//   ├── configuration-content.tsx
+//   ├── configuration-debug.tsx
+//   └── configuration-modals.tsx
+
+// configuration-header.tsx
+interface ConfigurationHeaderProps {
+  isAdvancedMode: boolean
+  onPublish: () => void
+}
+
+const ConfigurationHeader: FC<ConfigurationHeaderProps> = ({
+  isAdvancedMode,
+  onPublish,
+}) => {
+  const { t } = useTranslation()
+  
+  return (
+    <div className="header">
+      <h1>{t('configuration.title')}</h1>
+      <div className="actions">
+        {isAdvancedMode && <Badge>Advanced</Badge>}
+        <ModelParameterModal ... />
+        <AppPublisher onPublish={onPublish} />
+      </div>
+    </div>
+  )
+}
+
+// index.tsx (orchestration only)
+const ConfigurationPage = () => {
+  const { modelConfig, setModelConfig } = useModelConfig()
+  const { activeModal, openModal, closeModal } = useModalState()
+  
+  return (
+    <div>
+      <ConfigurationHeader
+        isAdvancedMode={isAdvancedMode}
+        onPublish={handlePublish}
+      />
+      <ConfigurationContent
+        modelConfig={modelConfig}
+        onConfigChange={setModelConfig}
+      />
+      {!isMobile && (
+        <ConfigurationDebug
+          inputs={inputs}
+          onSetting={handleSetting}
+        />
+      )}
+      <ConfigurationModals
+        activeModal={activeModal}
+        onClose={closeModal}
+      />
+    </div>
+  )
+}
+```
+
+### Strategy 2: Conditional Block Extraction
+
+Extract large conditional rendering blocks.
+
+```typescript
+// ❌ Before: Large conditional blocks
+const AppInfo = () => {
+  return (
+    <div>
+      {expand ? (
+        <div className="expanded">
+          {/* 100 lines of expanded view */}
+        </div>
+      ) : (
+        <div className="collapsed">
+          {/* 50 lines of collapsed view */}
+        </div>
+      )}
+    </div>
+  )
+}
+
+// ✅ After: Separate view components
+const AppInfoExpanded: FC<AppInfoViewProps> = ({ appDetail, onAction }) => {
+  return (
+    <div className="expanded">
+      {/* Clean, focused expanded view */}
+    </div>
+  )
+}
+
+const AppInfoCollapsed: FC<AppInfoViewProps> = ({ appDetail, onAction }) => {
+  return (
+    <div className="collapsed">
+      {/* Clean, focused collapsed view */}
+    </div>
+  )
+}
+
+const AppInfo = () => {
+  return (
+    <div>
+      {expand
+        ? <AppInfoExpanded appDetail={appDetail} onAction={handleAction} />
+        : <AppInfoCollapsed appDetail={appDetail} onAction={handleAction} />
+      }
+    </div>
+  )
+}
+```
+
+### Strategy 3: Modal Extraction
+
+Extract modals with their trigger logic.
+
+```typescript
+// ❌ Before: Multiple modals in one component
+const AppInfo = () => {
+  const [showEdit, setShowEdit] = useState(false)
+  const [showDuplicate, setShowDuplicate] = useState(false)
+  const [showDelete, setShowDelete] = useState(false)
+  const [showSwitch, setShowSwitch] = useState(false)
+  
+  const onEdit = async (data) => { /* 20 lines */ }
+  const onDuplicate = async (data) => { /* 20 lines */ }
+  const onDelete = async () => { /* 15 lines */ }
+  
+  return (
+    <div>
+      {/* Main content */}
+      
+      {showEdit && <EditModal onConfirm={onEdit} onClose={() => setShowEdit(false)} />}
+      {showDuplicate && <DuplicateModal onConfirm={onDuplicate} onClose={() => setShowDuplicate(false)} />}
+      {showDelete && <DeleteConfirm onConfirm={onDelete} onClose={() => setShowDelete(false)} />}
+      {showSwitch && <SwitchModal ... />}
+    </div>
+  )
+}
+
+// ✅ After: Modal manager component
+// app-info-modals.tsx
+type ModalType = 'edit' | 'duplicate' | 'delete' | 'switch' | null
+
+interface AppInfoModalsProps {
+  appDetail: AppDetail
+  activeModal: ModalType
+  onClose: () => void
+  onSuccess: () => void
+}
+
+const AppInfoModals: FC<AppInfoModalsProps> = ({
+  appDetail,
+  activeModal,
+  onClose,
+  onSuccess,
+}) => {
+  const handleEdit = async (data) => { /* logic */ }
+  const handleDuplicate = async (data) => { /* logic */ }
+  const handleDelete = async () => { /* logic */ }
+
+  return (
+    <>
+      {activeModal === 'edit' && (
+        <EditModal
+          appDetail={appDetail}
+          onConfirm={handleEdit}
+          onClose={onClose}
+        />
+      )}
+      {activeModal === 'duplicate' && (
+        <DuplicateModal
+          appDetail={appDetail}
+          onConfirm={handleDuplicate}
+          onClose={onClose}
+        />
+      )}
+      {activeModal === 'delete' && (
+        <DeleteConfirm
+          onConfirm={handleDelete}
+          onClose={onClose}
+        />
+      )}
+      {activeModal === 'switch' && (
+        <SwitchModal
+          appDetail={appDetail}
+          onClose={onClose}
+        />
+      )}
+    </>
+  )
+}
+
+// Parent component
+const AppInfo = () => {
+  const { activeModal, openModal, closeModal } = useModalState()
+  
+  return (
+    <div>
+      {/* Main content with openModal triggers */}
+      <Button onClick={() => openModal('edit')}>Edit</Button>
+      
+      <AppInfoModals
+        appDetail={appDetail}
+        activeModal={activeModal}
+        onClose={closeModal}
+        onSuccess={handleSuccess}
+      />
+    </div>
+  )
+}
+```
+
+### Strategy 4: List Item Extraction
+
+Extract repeated item rendering.
+
+```typescript
+// ❌ Before: Inline item rendering
+const OperationsList = () => {
+  return (
+    <div>
+      {operations.map(op => (
+        <div key={op.id} className="operation-item">
+          <span className="icon">{op.icon}</span>
+          <span className="title">{op.title}</span>
+          <span className="description">{op.description}</span>
+          <button onClick={() => op.onClick()}>
+            {op.actionLabel}
+          </button>
+          {op.badge && <Badge>{op.badge}</Badge>}
+          {/* More complex rendering... */}
+        </div>
+      ))}
+    </div>
+  )
+}
+
+// ✅ After: Extracted item component
+interface OperationItemProps {
+  operation: Operation
+  onAction: (id: string) => void
+}
+
+const OperationItem: FC<OperationItemProps> = ({ operation, onAction }) => {
+  return (
+    <div className="operation-item">
+      <span className="icon">{operation.icon}</span>
+      <span className="title">{operation.title}</span>
+      <span className="description">{operation.description}</span>
+      <button onClick={() => onAction(operation.id)}>
+        {operation.actionLabel}
+      </button>
+      {operation.badge && <Badge>{operation.badge}</Badge>}
+    </div>
+  )
+}
+
+const OperationsList = () => {
+  const handleAction = useCallback((id: string) => {
+    const op = operations.find(o => o.id === id)
+    op?.onClick()
+  }, [operations])
+
+  return (
+    <div>
+      {operations.map(op => (
+        <OperationItem
+          key={op.id}
+          operation={op}
+          onAction={handleAction}
+        />
+      ))}
+    </div>
+  )
+}
+```
+
+## Directory Structure Patterns
+
+### Pattern A: Flat Structure (Simple Components)
+
+For components with 2-3 sub-components:
+
+```
+component-name/
+  ├── index.tsx           # Main component
+  ├── sub-component-a.tsx
+  ├── sub-component-b.tsx
+  └── types.ts            # Shared types
+```
+
+### Pattern B: Nested Structure (Complex Components)
+
+For components with many sub-components:
+
+```
+component-name/
+  ├── index.tsx           # Main orchestration
+  ├── types.ts            # Shared types
+  ├── hooks/
+  │   ├── use-feature-a.ts
+  │   └── use-feature-b.ts
+  ├── components/
+  │   ├── header/
+  │   │   └── index.tsx
+  │   ├── content/
+  │   │   └── index.tsx
+  │   └── modals/
+  │       └── index.tsx
+  └── utils/
+      └── helpers.ts
+```
+
+### Pattern C: Feature-Based Structure (Dify Standard)
+
+Following Dify's existing patterns:
+
+```
+configuration/
+  ├── index.tsx           # Main page component
+  ├── base/               # Base/shared components
+  │   ├── feature-panel/
+  │   ├── group-name/
+  │   └── operation-btn/
+  ├── config/             # Config section
+  │   ├── index.tsx
+  │   ├── agent/
+  │   └── automatic/
+  ├── dataset-config/     # Dataset section
+  │   ├── index.tsx
+  │   ├── card-item/
+  │   └── params-config/
+  ├── debug/              # Debug section
+  │   ├── index.tsx
+  │   └── hooks.tsx
+  └── hooks/              # Shared hooks
+      └── use-advanced-prompt-config.ts
+```
+
+## Props Design
+
+### Minimal Props Principle
+
+Pass only what's needed:
+
+```typescript
+// ❌ Bad: Passing entire objects when only some fields needed
+<ConfigHeader appDetail={appDetail} modelConfig={modelConfig} />
+
+// ✅ Good: Destructure to minimum required
+<ConfigHeader
+  appName={appDetail.name}
+  isAdvancedMode={modelConfig.isAdvanced}
+  onPublish={handlePublish}
+/>
+```
+
+### Callback Props Pattern
+
+Use callbacks for child-to-parent communication:
+
+```typescript
+// Parent
+const Parent = () => {
+  const [value, setValue] = useState('')
+  
+  return (
+    <Child
+      value={value}
+      onChange={setValue}
+      onSubmit={handleSubmit}
+    />
+  )
+}
+
+// Child
+interface ChildProps {
+  value: string
+  onChange: (value: string) => void
+  onSubmit: () => void
+}
+
+const Child: FC<ChildProps> = ({ value, onChange, onSubmit }) => {
+  return (
+    <div>
+      <input value={value} onChange={e => onChange(e.target.value)} />
+      <button onClick={onSubmit}>Submit</button>
+    </div>
+  )
+}
+```
+
+### Render Props for Flexibility
+
+When sub-components need parent context:
+
+```typescript
+interface ListProps<T> {
+  items: T[]
+  renderItem: (item: T, index: number) => React.ReactNode
+  renderEmpty?: () => React.ReactNode
+}
+
+function List<T>({ items, renderItem, renderEmpty }: ListProps<T>) {
+  if (items.length === 0 && renderEmpty) {
+    return <>{renderEmpty()}</>
+  }
+  
+  return (
+    <div>
+      {items.map((item, index) => renderItem(item, index))}
+    </div>
+  )
+}
+
+// Usage
+<List
+  items={operations}
+  renderItem={(op, i) => <OperationItem key={i} operation={op} />}
+  renderEmpty={() => <EmptyState message="No operations" />}
+/>
+```

+# Hook Extraction Patterns
+
+This document provides detailed guidance on extracting custom hooks from complex components in Dify.
+
+## When to Extract Hooks
+
+Extract a custom hook when you identify:
+
+1. **Coupled state groups** - Multiple `useState` hooks that are always used together
+1. **Complex effects** - `useEffect` with multiple dependencies or cleanup logic
+1. **Business logic** - Data transformations, validations, or calculations
+1. **Reusable patterns** - Logic that appears in multiple components
+
+## Extraction Process
+
+### Step 1: Identify State Groups
+
+Look for state variables that are logically related:
+
+```typescript
+// ❌ These belong together - extract to hook
+const [modelConfig, setModelConfig] = useState<ModelConfig>(...)
+const [completionParams, setCompletionParams] = useState<FormValue>({})
+const [modelModeType, setModelModeType] = useState<ModelModeType>(...)
+
+// These are model-related state that should be in useModelConfig()
+```
+
+### Step 2: Identify Related Effects
+
+Find effects that modify the grouped state:
+
+```typescript
+// ❌ These effects belong with the state above
+useEffect(() => {
+  if (hasFetchedDetail && !modelModeType) {
+    const mode = currModel?.model_properties.mode
+    if (mode) {
+      const newModelConfig = produce(modelConfig, (draft) => {
+        draft.mode = mode
+      })
+      setModelConfig(newModelConfig)
+    }
+  }
+}, [textGenerationModelList, hasFetchedDetail, modelModeType, currModel])
+```
+
+### Step 3: Create the Hook
+
+```typescript
+// hooks/use-model-config.ts
+import type { FormValue } from '@/app/components/header/account-setting/model-provider-page/declarations'
+import type { ModelConfig } from '@/models/debug'
+import { produce } from 'immer'
+import { useEffect, useState } from 'react'

+
+### Step 4: Update Component
+
+```typescript
+// Before: 50+ lines of state management
+const Configuration: FC = () => {
+  const [modelConfig, setModelConfig] = useState<ModelConfig>(...)
+  // ... lots of related state and effects
+}
+
+// After: Clean component
+const Configuration: FC = () => {
+  const {
+    modelConfig,
+    setModelConfig,
+    completionParams,
+    setCompletionParams,
+    modelModeType,
+  } = useModelConfig({
+    currModel,
+    hasFetchedDetail,
+  })
+  
+  // Component now focuses on UI
+}
+```
+
+## Naming Conventions
+
+### Hook Names
+
+- Use `use` prefix: `useModelConfig`, `useDatasetConfig`
+- Be specific: `useAdvancedPromptConfig` not `usePrompt`
+- Include domain: `useWorkflowVariables`, `useMCPServer`
+
+### File Names
+
+- Kebab-case: `use-model-config.ts`
+- Place in `hooks/` subdirectory when multiple hooks exist
+- Place alongside component for single-use hooks
+
+### Return Type Names
+
+- Suffix with `Return`: `UseModelConfigReturn`
+- Suffix params with `Params`: `UseModelConfigParams`
+
+## Common Hook Patterns in Dify
+
+### 1. Data Fetching Hook (React Query)
+
+```typescript
+// Pattern: Use @tanstack/react-query for data fetching
+import { useQuery, useQueryClient } from '@tanstack/react-query'
+import { get } from '@/service/base'
+import { useInvalid } from '@/service/use-base'
+
+const NAME_SPACE = 'appConfig'
+
+// Query keys for cache management
+export const appConfigQueryKeys = {
+  detail: (appId: string) => [NAME_SPACE, 'detail', appId] as const,
+}
+
+// Main data hook
+export const useAppConfig = (appId: string) => {
+  return useQuery({
+    enabled: !!appId,
+    queryKey: appConfigQueryKeys.detail(appId),
+    queryFn: () => get<AppDetailResponse>(`/apps/${appId}`),
+    select: data => data?.model_config || null,
+  })
+}
+
+// Invalidation hook for refreshing data
+export const useInvalidAppConfig = () => {
+  return useInvalid([NAME_SPACE])
+}
+
+// Usage in component
+const Component = () => {
+  const { data: config, isLoading, error, refetch } = useAppConfig(appId)
+  const invalidAppConfig = useInvalidAppConfig()
+  
+  const handleRefresh = () => {
+    invalidAppConfig() // Invalidates cache and triggers refetch
+  }
+  
+  return <div>...</div>
+}
+```
+
+### 2. Form State Hook
+
+```typescript
+// Pattern: Form state + validation + submission
+export const useConfigForm = (initialValues: ConfigFormValues) => {
+  const [values, setValues] = useState(initialValues)
+  const [errors, setErrors] = useState<Record<string, string>>({})
+  const [isSubmitting, setIsSubmitting] = useState(false)
+
+  const validate = useCallback(() => {
+    const newErrors: Record<string, string> = {}
+    if (!values.name) newErrors.name = 'Name is required'
+    setErrors(newErrors)
+    return Object.keys(newErrors).length === 0
+  }, [values])
+
+  const handleChange = useCallback((field: string, value: any) => {
+    setValues(prev => ({ ...prev, [field]: value }))
+  }, [])
+
+  const handleSubmit = useCallback(async (onSubmit: (values: ConfigFormValues) => Promise<void>) => {
+    if (!validate()) return
+    setIsSubmitting(true)
+    try {
+      await onSubmit(values)
+    } finally {
+      setIsSubmitting(false)
+    }
+  }, [values, validate])
+
+  return { values, errors, isSubmitting, handleChange, handleSubmit }
+}
+```
+
+### 3. Modal State Hook
+
+```typescript
+// Pattern: Multiple modal management
+type ModalType = 'edit' | 'delete' | 'duplicate' | null
+
+export const useModalState = () => {
+  const [activeModal, setActiveModal] = useState<ModalType>(null)
+  const [modalData, setModalData] = useState<any>(null)
+
+  const openModal = useCallback((type: ModalType, data?: any) => {
+    setActiveModal(type)
+    setModalData(data)
+  }, [])
+
+  const closeModal = useCallback(() => {
+    setActiveModal(null)
+    setModalData(null)
+  }, [])
+
+  return {
+    activeModal,
+    modalData,
+    openModal,
+    closeModal,
+    isOpen: useCallback((type: ModalType) => activeModal === type, [activeModal]),
+  }
+}
+```
+
+### 4. Toggle/Boolean Hook
+
+```typescript
+// Pattern: Boolean state with convenience methods
+export const useToggle = (initialValue = false) => {
+  const [value, setValue] = useState(initialValue)
+
+  const toggle = useCallback(() => setValue(v => !v), [])
+  const setTrue = useCallback(() => setValue(true), [])
+  const setFalse = useCallback(() => setValue(false), [])
+
+  return [value, { toggle, setTrue, setFalse, set: setValue }] as const
+}
+
+// Usage
+const [isExpanded, { toggle, setTrue: expand, setFalse: collapse }] = useToggle()
+```
+
+## Testing Extracted Hooks
+
+After extraction, test hooks in isolation:
+
+```typescript
+// use-model-config.spec.ts
+import { renderHook, act } from '@testing-library/react'
+import { useModelConfig } from './use-model-config'
+
+describe('useModelConfig', () => {
+  it('should initialize with default values', () => {
+    const { result } = renderHook(() => useModelConfig({
+      hasFetchedDetail: false,
+    }))
+
+    expect(result.current.modelConfig.provider).toBe('langgenius/openai/openai')
+    expect(result.current.modelModeType).toBe(ModelModeType.unset)
+  })
+
+  it('should update model config', () => {
+    const { result } = renderHook(() => useModelConfig({
+      hasFetchedDetail: true,
+    }))
+
+    act(() => {
+      result.current.setModelConfig({
+        ...result.current.modelConfig,
+        model_id: 'gpt-4',
+      })
+    })
+
+    expect(result.current.modelConfig.model_id).toBe('gpt-4')
+  })
+})
+```

+# Dify Frontend Testing Skill
+
+This skill enables Claude to generate high-quality, comprehensive frontend tests for the Dify project following established conventions and best practices.
+
+> **⚠️ Authoritative Source**: This skill is derived from `web/testing/testing.md`. Use Vitest mock/timer APIs (`vi.*`).
+
+## When to Apply This Skill
+
+Apply this skill when the user:
+
+- Asks to **write tests** for a component, hook, or utility
+- Asks to **review existing tests** for completeness
+- Mentions **Vitest**, **React Testing Library**, **RTL**, or **spec files**
+- Requests **test coverage** improvement
+- Uses `pnpm analyze-component` output as context
+- Mentions **testing**, **unit tests**, or **integration tests** for frontend code
+- Wants to understand **testing patterns** in the Dify codebase
+
+**Do NOT apply** when:
+
+- User is asking about backend/API tests (Python/pytest)
+- User is asking about E2E tests (Playwright/Cypress)
+- User is only asking conceptual questions without code context

+## Test Structure Template
+
+```typescript
+import { render, screen, fireEvent, waitFor } from '@testing-library/react'
+import Component from './index'
+
+// ✅ Import real project components (DO NOT mock these)
+// import Loading from '@/app/components/base/loading'
+// import { ChildComponent } from './child-component'
+
+// ✅ Mock external dependencies only
+vi.mock('@/service/api')
+vi.mock('next/navigation', () => ({
+  useRouter: () => ({ push: vi.fn() }),
+  usePathname: () => '/test',
+}))
+
+// Shared state for mocks (if needed)
+let mockSharedState = false
+
+describe('ComponentName', () => {
+  beforeEach(() => {
+    vi.clearAllMocks()  // ✅ Reset mocks BEFORE each test
+    mockSharedState = false  // ✅ Reset shared state
+  })
+
+  // Rendering tests (REQUIRED)
+  describe('Rendering', () => {
+    it('should render without crashing', () => {
+      // Arrange
+      const props = { title: 'Test' }
+      
+      // Act
+      render(<Component {...props} />)
+      
+      // Assert
+      expect(screen.getByText('Test')).toBeInTheDocument()
+    })
+  })
+
+  // Props tests (REQUIRED)
+  describe('Props', () => {
+    it('should apply custom className', () => {
+      render(<Component className="custom" />)
+      expect(screen.getByRole('button')).toHaveClass('custom')
+    })
+  })
+
+  // User Interactions
+  describe('User Interactions', () => {
+    it('should handle click events', () => {
+      const handleClick = vi.fn()
+      render(<Component onClick={handleClick} />)
+      
+      fireEvent.click(screen.getByRole('button'))
+      
+      expect(handleClick).toHaveBeenCalledTimes(1)
+    })
+  })
+
+  // Edge Cases (REQUIRED)
+  describe('Edge Cases', () => {
+    it('should handle null data', () => {
+      render(<Component data={null} />)
+      expect(screen.getByText(/no data/i)).toBeInTheDocument()
+    })
+
+    it('should handle empty array', () => {
+      render(<Component items={[]} />)
+      expect(screen.getByText(/empty/i)).toBeInTheDocument()
+    })
+  })
+})
+```
+
+## Testing Workflow (CRITICAL)
+
+### ⚠️ Incremental Approach Required
+
+**NEVER generate all test files at once.** For complex components or multi-file directories:
+
+1. **Analyze & Plan**: List all files, order by complexity (simple → complex)
+1. **Process ONE at a time**: Write test → Run test → Fix if needed → Next
+1. **Verify before proceeding**: Do NOT continue to next file until current passes
+
+```
+For each file:
+  ┌────────────────────────────────────────┐
+  │ 1. Write test                          │
+  │ 2. Run: pnpm test <file>.spec.tsx      │
+  │ 3. PASS? → Mark complete, next file    │
+  │    FAIL? → Fix first, then continue    │
+  └────────────────────────────────────────┘
+```
+
+### Complexity-Based Order
+
+Process in this order for multi-file testing:
+
+1. 🟢 Utility functions (simplest)
+1. 🟢 Custom hooks
+1. 🟡 Simple components (presentational)
+1. 🟡 Medium components (state, effects)
+1. 🔴 Complex components (API, routing)
+1. 🔴 Integration tests (index files - last)
+
+### When to Refactor First
+
+- **Complexity > 50**: Break into smaller pieces before testing
+- **500+ lines**: Consider splitting before testing
+- **Many dependencies**: Extract logic into hooks first
+
+> 📖 See `references/workflow.md` for complete workflow details and todo list format.
+
+## Testing Strategy
+
+### Path-Level Testing (Directory Testing)
+
+When assigned to test a directory/path, test **ALL content** within that path:
+
+- Test all components, hooks, utilities in the directory (not just `index` file)
+- Use incremental approach: one file at a time, verify each before proceeding
+- Goal: 100% coverage of ALL files in the directory
+
+### Integration Testing First
+
+**Prefer integration testing** when writing tests for a directory:
+
+- ✅ **Import real project components** directly (including base components and siblings)
+- ✅ **Only mock**: API services (`@/service/*`), `next/navigation`, complex context providers
+- ❌ **DO NOT mock** base components (`@/app/components/base/*`)
+- ❌ **DO NOT mock** sibling/child components in the same directory
+
+> See [Test Structure Template](#test-structure-template) for correct import/mock patterns.
+
+## Core Principles
+
+### 1. AAA Pattern (Arrange-Act-Assert)
+
+Every test should clearly separate:
+
+- **Arrange**: Setup test data and render component
+- **Act**: Perform user actions
+- **Assert**: Verify expected outcomes
+
+### 2. Black-Box Testing
+
+- Test observable behavior, not implementation details
+- Use semantic queries (getByRole, getByLabelText)
+- Avoid testing internal state directly
+- **Prefer pattern matching over hardcoded strings** in assertions:
+
+```typescript
+// ❌ Avoid: hardcoded text assertions
+expect(screen.getByText('Loading...')).toBeInTheDocument()
+
+// ✅ Better: role-based queries
+expect(screen.getByRole('status')).toBeInTheDocument()
+
+// ✅ Better: pattern matching
+expect(screen.getByText(/loading/i)).toBeInTheDocument()
+```
+
+### 3. Single Behavior Per Test
+
+Each test verifies ONE user-observable behavior:
+
+```typescript
+// ✅ Good: One behavior
+it('should disable button when loading', () => {
+  render(<Button loading />)
+  expect(screen.getByRole('button')).toBeDisabled()
+})
+
+// ❌ Bad: Multiple behaviors
+it('should handle loading state', () => {
+  render(<Button loading />)
+  expect(screen.getByRole('button')).toBeDisabled()
+  expect(screen.getByText('Loading...')).toBeInTheDocument()
+  expect(screen.getByRole('button')).toHaveClass('loading')
+})
+```
+
+### 4. Semantic Naming
+
+Use `should <behavior> when <condition>`:
+
+```typescript
+it('should show error message when validation fails')
+it('should call onSubmit when form is valid')
+it('should disable input when isReadOnly is true')
+```
+
+## Required Test Scenarios
+
+### Always Required (All Components)
+
+1. **Rendering**: Component renders without crashing
+1. **Props**: Required props, optional props, default values
+1. **Edge Cases**: null, undefined, empty values, boundary conditions
+
+### Conditional (When Present)
+
+| Feature | Test Focus |
+|---------|-----------|
+| `useState` | Initial state, transitions, cleanup |
+| `useEffect` | Execution, dependencies, cleanup |
+| Event handlers | All onClick, onChange, onSubmit, keyboard |
+| API calls | Loading, success, error states |
+| Routing | Navigation, params, query strings |
+| `useCallback`/`useMemo` | Referential equality |
+| Context | Provider values, consumer behavior |
+| Forms | Validation, submission, error display |
+
+## Coverage Goals (Per File)
+
+For each test file generated, aim for:
+
+- ✅ **100%** function coverage
+- ✅ **100%** statement coverage
+- ✅ **>95%** branch coverage
+- ✅ **>95%** line coverage
+
+> **Note**: For multi-file directories, process one file at a time with full coverage each. See `references/workflow.md`.

+## Authoritative References
+
+### Primary Specification (MUST follow)
+
+- **`web/testing/testing.md`** - The canonical testing specification. This skill is derived from this document.
+
+### Reference Examples in Codebase
+
+- `web/utils/classnames.spec.ts` - Utility function tests
+- `web/app/components/base/button/index.spec.tsx` - Component tests
+- `web/__mocks__/provider-context.ts` - Mock factory example
+
+### Project Configuration
+
+- `web/vitest.config.ts` - Vitest configuration
+- `web/vitest.setup.ts` - Test environment setup
+- `web/scripts/analyze-component.js` - Component analysis tool
+- Modules are not mocked automatically. Global mocks live in `web/vitest.setup.ts` (for example `react-i18next`, `next/image`); mock other modules like `ky` or `mime` locally in test files.

+// They run BEFORE imports, so keep them before component imports.
+
+// i18n (automatically mocked)
+// WHY: Global mock in web/vitest.setup.ts is auto-loaded by Vitest setup

+# Async Testing Guide
+
+## Core Async Patterns
+
+### 1. waitFor - Wait for Condition
+
+```typescript
+import { render, screen, waitFor } from '@testing-library/react'
+
+it('should load and display data', async () => {
+  render(<DataComponent />)
+  
+  // Wait for element to appear
+  await waitFor(() => {
+    expect(screen.getByText('Loaded Data')).toBeInTheDocument()
+  })
+})
+
+it('should hide loading spinner after load', async () => {
+  render(<DataComponent />)
+  
+  // Wait for element to disappear
+  await waitFor(() => {
+    expect(screen.queryByText('Loading...')).not.toBeInTheDocument()
+  })
+})
+```
+
+### 2. findBy\* - Async Queries
+
+```typescript
+it('should show user name after fetch', async () => {
+  render(<UserProfile />)
+  
+  // findBy returns a promise, auto-waits up to 1000ms
+  const userName = await screen.findByText('John Doe')
+  expect(userName).toBeInTheDocument()
+  
+  // findByRole with options
+  const button = await screen.findByRole('button', { name: /submit/i })
+  expect(button).toBeEnabled()
+})
+```
+
+### 3. userEvent for Async Interactions
+
+```typescript
+import userEvent from '@testing-library/user-event'
+
+it('should submit form', async () => {
+  const user = userEvent.setup()
+  const onSubmit = vi.fn()
+  
+  render(<Form onSubmit={onSubmit} />)
+  
+  // userEvent methods are async
+  await user.type(screen.getByLabelText('Email'), 'test@example.com')
+  await user.click(screen.getByRole('button', { name: /submit/i }))
+  
+  await waitFor(() => {
+    expect(onSubmit).toHaveBeenCalledWith({ email: 'test@example.com' })
+  })
+})
+```
+
+## Fake Timers
+
+### When to Use Fake Timers
+
+- Testing components with `setTimeout`/`setInterval`
+- Testing debounce/throttle behavior
+- Testing animations or delayed transitions
+- Testing polling or retry logic
+
+### Basic Fake Timer Setup
+
+```typescript
+describe('Debounced Search', () => {
+  beforeEach(() => {
+    vi.useFakeTimers()
+  })
+
+  afterEach(() => {
+    vi.useRealTimers()
+  })
+
+  it('should debounce search input', async () => {
+    const onSearch = vi.fn()
+    render(<SearchInput onSearch={onSearch} debounceMs={300} />)
+    
+    // Type in the input
+    fireEvent.change(screen.getByRole('textbox'), { target: { value: 'query' } })
+    
+    // Search not called immediately
+    expect(onSearch).not.toHaveBeenCalled()
+    
+    // Advance timers
+    vi.advanceTimersByTime(300)
+    
+    // Now search is called
+    expect(onSearch).toHaveBeenCalledWith('query')
+  })
+})
+```
+
+### Fake Timers with Async Code
+
+```typescript
+it('should retry on failure', async () => {
+  vi.useFakeTimers()
+  const fetchData = vi.fn()
+    .mockRejectedValueOnce(new Error('Network error'))
+    .mockResolvedValueOnce({ data: 'success' })
+  
+  render(<RetryComponent fetchData={fetchData} retryDelayMs={1000} />)
+  
+  // First call fails
+  await waitFor(() => {
+    expect(fetchData).toHaveBeenCalledTimes(1)
+  })
+  
+  // Advance timer for retry
+  vi.advanceTimersByTime(1000)
+  
+  // Second call succeeds
+  await waitFor(() => {
+    expect(fetchData).toHaveBeenCalledTimes(2)
+    expect(screen.getByText('success')).toBeInTheDocument()
+  })
+  
+  vi.useRealTimers()
+})
+```
+
+### Common Fake Timer Utilities
+
+```typescript
+// Run all pending timers
+vi.runAllTimers()
+
+// Run only pending timers (not new ones created during execution)
+vi.runOnlyPendingTimers()
+
+// Advance by specific time
+vi.advanceTimersByTime(1000)
+
+// Get current fake time
+Date.now()
+
+// Clear all timers
+vi.clearAllTimers()
+```
+
+## API Testing Patterns
+
+### Loading → Success → Error States
+
+```typescript
+describe('DataFetcher', () => {
+  beforeEach(() => {
+    vi.clearAllMocks()
+  })
+
+  it('should show loading state', () => {
+    mockedApi.fetchData.mockImplementation(() => new Promise(() => {})) // Never resolves
+    
+    render(<DataFetcher />)
+    
+    expect(screen.getByTestId('loading-spinner')).toBeInTheDocument()
+  })
+
+  it('should show data on success', async () => {
+    mockedApi.fetchData.mockResolvedValue({ items: ['Item 1', 'Item 2'] })
+    
+    render(<DataFetcher />)
+    
+    // Use findBy* for multiple async elements (better error messages than waitFor with multiple assertions)
+    const item1 = await screen.findByText('Item 1')
+    const item2 = await screen.findByText('Item 2')
+    expect(item1).toBeInTheDocument()
+    expect(item2).toBeInTheDocument()
+    
+    expect(screen.queryByTestId('loading-spinner')).not.toBeInTheDocument()
+  })
+
+  it('should show error on failure', async () => {
+    mockedApi.fetchData.mockRejectedValue(new Error('Failed to fetch'))
+    
+    render(<DataFetcher />)
+    
+    await waitFor(() => {
+      expect(screen.getByText(/failed to fetch/i)).toBeInTheDocument()
+    })
+  })
+
+  it('should retry on error', async () => {
+    mockedApi.fetchData.mockRejectedValue(new Error('Network error'))
+    
+    render(<DataFetcher />)
+    
+    await waitFor(() => {
+      expect(screen.getByRole('button', { name: /retry/i })).toBeInTheDocument()
+    })
+    
+    mockedApi.fetchData.mockResolvedValue({ items: ['Item 1'] })
+    fireEvent.click(screen.getByRole('button', { name: /retry/i }))
+    
+    await waitFor(() => {
+      expect(screen.getByText('Item 1')).toBeInTheDocument()
+    })
+  })
+})
+```
+
+### Testing Mutations
+
+```typescript
+it('should submit form and show success', async () => {
+  const user = userEvent.setup()
+  mockedApi.createItem.mockResolvedValue({ id: '1', name: 'New Item' })
+  
+  render(<CreateItemForm />)
+  
+  await user.type(screen.getByLabelText('Name'), 'New Item')
+  await user.click(screen.getByRole('button', { name: /create/i }))
+  
+  // Button should be disabled during submission
+  expect(screen.getByRole('button', { name: /creating/i })).toBeDisabled()
+  
+  await waitFor(() => {
+    expect(screen.getByText(/created successfully/i)).toBeInTheDocument()
+  })
+  
+  expect(mockedApi.createItem).toHaveBeenCalledWith({ name: 'New Item' })
+})
+```
+
+## useEffect Testing
+
+### Testing Effect Execution
+
+```typescript
+it('should fetch data on mount', async () => {
+  const fetchData = vi.fn().mockResolvedValue({ data: 'test' })
+  
+  render(<ComponentWithEffect fetchData={fetchData} />)
+  
+  await waitFor(() => {
+    expect(fetchData).toHaveBeenCalledTimes(1)
+  })
+})
+```
+
+### Testing Effect Dependencies
+
+```typescript
+it('should refetch when id changes', async () => {
+  const fetchData = vi.fn().mockResolvedValue({ data: 'test' })
+  
+  const { rerender } = render(<ComponentWithEffect id="1" fetchData={fetchData} />)
+  
+  await waitFor(() => {
+    expect(fetchData).toHaveBeenCalledWith('1')
+  })
+  
+  rerender(<ComponentWithEffect id="2" fetchData={fetchData} />)
+  
+  await waitFor(() => {
+    expect(fetchData).toHaveBeenCalledWith('2')
+    expect(fetchData).toHaveBeenCalledTimes(2)
+  })
+})
+```
+
+### Testing Effect Cleanup
+
+```typescript
+it('should cleanup subscription on unmount', () => {
+  const subscribe = vi.fn()
+  const unsubscribe = vi.fn()
+  subscribe.mockReturnValue(unsubscribe)
+  
+  const { unmount } = render(<SubscriptionComponent subscribe={subscribe} />)
+  
+  expect(subscribe).toHaveBeenCalledTimes(1)
+  
+  unmount()
+  
+  expect(unsubscribe).toHaveBeenCalledTimes(1)
+})
+```
+
+## Common Async Pitfalls
+
+### ❌ Don't: Forget to await
+
+```typescript
+// Bad - test may pass even if assertion fails
+it('should load data', () => {
+  render(<Component />)
+  waitFor(() => {
+    expect(screen.getByText('Data')).toBeInTheDocument()
+  })
+})
+
+// Good - properly awaited
+it('should load data', async () => {
+  render(<Component />)
+  await waitFor(() => {
+    expect(screen.getByText('Data')).toBeInTheDocument()
+  })
+})
+```
+
+### ❌ Don't: Use multiple assertions in single waitFor
+
+```typescript
+// Bad - if first assertion fails, won't know about second
+await waitFor(() => {
+  expect(screen.getByText('Title')).toBeInTheDocument()
+  expect(screen.getByText('Description')).toBeInTheDocument()
+})
+
+// Good - separate waitFor or use findBy
+const title = await screen.findByText('Title')
+const description = await screen.findByText('Description')
+expect(title).toBeInTheDocument()
+expect(description).toBeInTheDocument()
+```
+
+### ❌ Don't: Mix fake timers with real async
+
+```typescript
+// Bad - fake timers don't work well with real Promises
+vi.useFakeTimers()
+await waitFor(() => {
+  expect(screen.getByText('Data')).toBeInTheDocument()
+}) // May timeout!
+
+// Good - use runAllTimers or advanceTimersByTime
+vi.useFakeTimers()
+render(<Component />)
+vi.runAllTimers()
+expect(screen.getByText('Data')).toBeInTheDocument()
+```

+# Test Generation Checklist
+
+Use this checklist when generating or reviewing tests for Dify frontend components.
+
+## Pre-Generation
+
+- [ ] Read the component source code completely
+- [ ] Identify component type (component, hook, utility, page)
+- [ ] Run `pnpm analyze-component <path>` if available
+- [ ] Note complexity score and features detected
+- [ ] Check for existing tests in the same directory
+- [ ] **Identify ALL files in the directory** that need testing (not just index)
+
+## Testing Strategy
+
+### ⚠️ Incremental Workflow (CRITICAL for Multi-File)
+
+- [ ] **NEVER generate all tests at once** - process one file at a time
+- [ ] Order files by complexity: utilities → hooks → simple → complex → integration
+- [ ] Create a todo list to track progress before starting
+- [ ] For EACH file: write → run test → verify pass → then next
+- [ ] **DO NOT proceed** to next file until current one passes
+
+### Path-Level Coverage
+
+- [ ] **Test ALL files** in the assigned directory/path
+- [ ] List all components, hooks, utilities that need coverage
+- [ ] Decide: single spec file (integration) or multiple spec files (unit)
+
+### Complexity Assessment
+
+- [ ] Run `pnpm analyze-component <path>` for complexity score
+- [ ] **Complexity > 50**: Consider refactoring before testing
+- [ ] **500+ lines**: Consider splitting before testing
+- [ ] **30-50 complexity**: Use multiple describe blocks, organized structure
+
+### Integration vs Mocking
+
+- [ ] **DO NOT mock base components** (`Loading`, `Button`, `Tooltip`, etc.)
+- [ ] Import real project components instead of mocking
+- [ ] Only mock: API calls, complex context providers, third-party libs with side effects
+- [ ] Prefer integration testing when using single spec file
+
+## Required Test Sections
+
+### All Components MUST Have
+
+- [ ] **Rendering tests** - Component renders without crashing
+- [ ] **Props tests** - Required props, optional props, default values
+- [ ] **Edge cases** - null, undefined, empty values, boundaries
+
+### Conditional Sections (Add When Feature Present)
+
+| Feature | Add Tests For |
+|---------|---------------|
+| `useState` | Initial state, transitions, cleanup |
+| `useEffect` | Execution, dependencies, cleanup |
+| Event handlers | onClick, onChange, onSubmit, keyboard |
+| API calls | Loading, success, error states |
+| Routing | Navigation, params, query strings |
+| `useCallback`/`useMemo` | Referential equality |
+| Context | Provider values, consumer behavior |
+| Forms | Validation, submission, error display |
+
+## Code Quality Checklist
+
+### Structure
+
+- [ ] Uses `describe` blocks to group related tests
+- [ ] Test names follow `should <behavior> when <condition>` pattern
+- [ ] AAA pattern (Arrange-Act-Assert) is clear
+- [ ] Comments explain complex test scenarios
+
+### Mocks
+
+- [ ] **DO NOT mock base components** (`@/app/components/base/*`)
+- [ ] `vi.clearAllMocks()` in `beforeEach` (not `afterEach`)
+- [ ] Shared mock state reset in `beforeEach`
+- [ ] i18n uses global mock (auto-loaded in `web/vitest.setup.ts`); only override locally for custom translations
+- [ ] Router mocks match actual Next.js API
+- [ ] Mocks reflect actual component conditional behavior
+- [ ] Only mock: API services, complex context providers, third-party libs
+
+### Queries
+
+- [ ] Prefer semantic queries (`getByRole`, `getByLabelText`)
+- [ ] Use `queryBy*` for absence assertions
+- [ ] Use `findBy*` for async elements
+- [ ] `getByTestId` only as last resort
+
+### Async
+
+- [ ] All async tests use `async/await`
+- [ ] `waitFor` wraps async assertions
+- [ ] Fake timers properly setup/teardown
+- [ ] No floating promises
+
+### TypeScript
+
+- [ ] No `any` types without justification
+- [ ] Mock data uses actual types from source
+- [ ] Factory functions have proper return types
+
+## Coverage Goals (Per File)
+
+For the current file being tested:
+
+- [ ] 100% function coverage
+- [ ] 100% statement coverage
+- [ ] >95% branch coverage
+- [ ] >95% line coverage
+
+## Post-Generation (Per File)
+
+**Run these checks after EACH test file, not just at the end:**
+
+- [ ] Run `pnpm test path/to/file.spec.tsx` - **MUST PASS before next file**
+- [ ] Fix any failures immediately
+- [ ] Mark file as complete in todo list
+- [ ] Only then proceed to next file
+
+### After All Files Complete
+
+- [ ] Run full directory test: `pnpm test path/to/directory/`
+- [ ] Check coverage report: `pnpm test:coverage`
+- [ ] Run `pnpm lint:fix` on all test files
+- [ ] Run `pnpm type-check:tsgo`
+
+## Common Issues to Watch
+
+### False Positives
+
+```typescript
+// ❌ Mock doesn't match actual behavior
+vi.mock('./Component', () => () => <div>Mocked</div>)
+
+// ✅ Mock matches actual conditional logic
+vi.mock('./Component', () => ({ isOpen }: any) =>
+  isOpen ? <div>Content</div> : null
+)
+```
+
+### State Leakage
+
+```typescript
+// ❌ Shared state not reset
+let mockState = false
+vi.mock('./useHook', () => () => mockState)
+
+// ✅ Reset in beforeEach
+beforeEach(() => {
+  mockState = false
+})
+```
+
+### Async Race Conditions
+
+```typescript
+// ❌ Not awaited
+it('loads data', () => {
+  render(<Component />)
+  expect(screen.getByText('Data')).toBeInTheDocument()
+})
+
+// ✅ Properly awaited
+it('loads data', async () => {
+  render(<Component />)
+  await waitFor(() => {
+    expect(screen.getByText('Data')).toBeInTheDocument()
+  })
+})
+```
+
+### Missing Edge Cases
+
+Always test these scenarios:
+
+- `null` / `undefined` inputs
+- Empty strings / arrays / objects
+- Boundary values (0, -1, MAX_INT)
+- Error states
+- Loading states
+- Disabled states
+
+## Quick Commands
+
+```bash
+# Run specific test
+pnpm test path/to/file.spec.tsx
+
+# Run with coverage
+pnpm test:coverage path/to/file.spec.tsx
+
+# Watch mode
+pnpm test:watch path/to/file.spec.tsx
+
+# Update snapshots (use sparingly)
+pnpm test -u path/to/file.spec.tsx
+
+# Analyze component
+pnpm analyze-component path/to/component.tsx
+
+# Review existing test
+pnpm analyze-component path/to/component.tsx --review
+```

+# Common Testing Patterns
+
+## Query Priority
+
+Use queries in this order (most to least preferred):
+
+```typescript
+// 1. getByRole - Most recommended (accessibility)
+screen.getByRole('button', { name: /submit/i })
+screen.getByRole('textbox', { name: /email/i })
+screen.getByRole('heading', { level: 1 })
+
+// 2. getByLabelText - Form fields
+screen.getByLabelText('Email address')
+screen.getByLabelText(/password/i)
+
+// 3. getByPlaceholderText - When no label
+screen.getByPlaceholderText('Search...')
+
+// 4. getByText - Non-interactive elements
+screen.getByText('Welcome to Dify')
+screen.getByText(/loading/i)
+
+// 5. getByDisplayValue - Current input value
+screen.getByDisplayValue('current value')
+
+// 6. getByAltText - Images
+screen.getByAltText('Company logo')
+
+// 7. getByTitle - Tooltip elements
+screen.getByTitle('Close')
+
+// 8. getByTestId - Last resort only!
+screen.getByTestId('custom-element')
+```
+
+## Event Handling Patterns
+
+### Click Events
+
+```typescript
+// Basic click
+fireEvent.click(screen.getByRole('button'))
+
+// With userEvent (preferred for realistic interaction)
+const user = userEvent.setup()
+await user.click(screen.getByRole('button'))
+
+// Double click
+await user.dblClick(screen.getByRole('button'))
+
+// Right click
+await user.pointer({ keys: '[MouseRight]', target: screen.getByRole('button') })
+```
+
+### Form Input
+
+```typescript
+const user = userEvent.setup()
+
+// Type in input
+await user.type(screen.getByRole('textbox'), 'Hello World')
+
+// Clear and type
+await user.clear(screen.getByRole('textbox'))
+await user.type(screen.getByRole('textbox'), 'New value')
+
+// Select option
+await user.selectOptions(screen.getByRole('combobox'), 'option-value')
+
+// Check checkbox
+await user.click(screen.getByRole('checkbox'))
+
+// Upload file
+const file = new File(['content'], 'test.pdf', { type: 'application/pdf' })
+await user.upload(screen.getByLabelText(/upload/i), file)
+```
+
+### Keyboard Events
+
+```typescript
+const user = userEvent.setup()
+
+// Press Enter
+await user.keyboard('{Enter}')
+
+// Press Escape
+await user.keyboard('{Escape}')
+
+// Keyboard shortcut
+await user.keyboard('{Control>}a{/Control}') // Ctrl+A
+
+// Tab navigation
+await user.tab()
+
+// Arrow keys
+await user.keyboard('{ArrowDown}')
+await user.keyboard('{ArrowUp}')
+```
+
+## Component State Testing
+
+### Testing State Transitions
+
+```typescript
+describe('Counter', () => {
+  it('should increment count', async () => {
+    const user = userEvent.setup()
+    render(<Counter initialCount={0} />)
+    
+    // Initial state
+    expect(screen.getByText('Count: 0')).toBeInTheDocument()
+    
+    // Trigger transition
+    await user.click(screen.getByRole('button', { name: /increment/i }))
+    
+    // New state
+    expect(screen.getByText('Count: 1')).toBeInTheDocument()
+  })
+})
+```
+
+### Testing Controlled Components
+
+```typescript
+describe('ControlledInput', () => {
+  it('should call onChange with new value', async () => {
+    const user = userEvent.setup()
+    const handleChange = vi.fn()
+    
+    render(<ControlledInput value="" onChange={handleChange} />)
+    
+    await user.type(screen.getByRole('textbox'), 'a')
+    
+    expect(handleChange).toHaveBeenCalledWith('a')
+  })
+
+  it('should display controlled value', () => {
+    render(<ControlledInput value="controlled" onChange={vi.fn()} />)
+    
+    expect(screen.getByRole('textbox')).toHaveValue('controlled')
+  })
+})
+```
+
+## Conditional Rendering Testing
+
+```typescript
+describe('ConditionalComponent', () => {
+  it('should show loading state', () => {
+    render(<DataDisplay isLoading={true} data={null} />)
+    
+    expect(screen.getByText(/loading/i)).toBeInTheDocument()
+    expect(screen.queryByTestId('data-content')).not.toBeInTheDocument()
+  })
+
+  it('should show error state', () => {
+    render(<DataDisplay isLoading={false} data={null} error="Failed to load" />)
+    
+    expect(screen.getByText(/failed to load/i)).toBeInTheDocument()
+  })
+
+  it('should show data when loaded', () => {
+    render(<DataDisplay isLoading={false} data={{ name: 'Test' }} />)
+    
+    expect(screen.getByText('Test')).toBeInTheDocument()
+  })
+
+  it('should show empty state when no data', () => {
+    render(<DataDisplay isLoading={false} data={[]} />)
+    
+    expect(screen.getByText(/no data/i)).toBeInTheDocument()
+  })
+})
+```
+
+## List Rendering Testing
+
+```typescript
+describe('ItemList', () => {
+  const items = [
+    { id: '1', name: 'Item 1' },
+    { id: '2', name: 'Item 2' },
+    { id: '3', name: 'Item 3' },
+  ]
+
+  it('should render all items', () => {
+    render(<ItemList items={items} />)
+    
+    expect(screen.getAllByRole('listitem')).toHaveLength(3)
+    items.forEach(item => {
+      expect(screen.getByText(item.name)).toBeInTheDocument()
+    })
+  })
+
+  it('should handle item selection', async () => {
+    const user = userEvent.setup()
+    const onSelect = vi.fn()
+    
+    render(<ItemList items={items} onSelect={onSelect} />)
+    
+    await user.click(screen.getByText('Item 2'))
+    
+    expect(onSelect).toHaveBeenCalledWith(items[1])
+  })
+
+  it('should handle empty list', () => {
+    render(<ItemList items={[]} />)
+    
+    expect(screen.getByText(/no items/i)).toBeInTheDocument()
+  })
+})
+```
+
+## Modal/Dialog Testing
+
+```typescript
+describe('Modal', () => {
+  it('should not render when closed', () => {
+    render(<Modal isOpen={false} onClose={vi.fn()} />)
+    
+    expect(screen.queryByRole('dialog')).not.toBeInTheDocument()
+  })
+
+  it('should render when open', () => {
+    render(<Modal isOpen={true} onClose={vi.fn()} />)
+    
+    expect(screen.getByRole('dialog')).toBeInTheDocument()
+  })
+
+  it('should call onClose when clicking overlay', async () => {
+    const user = userEvent.setup()
+    const handleClose = vi.fn()
+    
+    render(<Modal isOpen={true} onClose={handleClose} />)
+    
+    await user.click(screen.getByTestId('modal-overlay'))
+    
+    expect(handleClose).toHaveBeenCalled()
+  })
+
+  it('should call onClose when pressing Escape', async () => {
+    const user = userEvent.setup()
+    const handleClose = vi.fn()
+    
+    render(<Modal isOpen={true} onClose={handleClose} />)
+    
+    await user.keyboard('{Escape}')
+    
+    expect(handleClose).toHaveBeenCalled()
+  })
+
+  it('should trap focus inside modal', async () => {
+    const user = userEvent.setup()
+    
+    render(
+      <Modal isOpen={true} onClose={vi.fn()}>
+        <button>First</button>
+        <button>Second</button>
+      </Modal>
+    )
+    
+    // Focus should cycle within modal
+    await user.tab()
+    expect(screen.getByText('First')).toHaveFocus()
+    
+    await user.tab()
+    expect(screen.getByText('Second')).toHaveFocus()
+    
+    await user.tab()
+    expect(screen.getByText('First')).toHaveFocus() // Cycles back
+  })
+})
+```
+
+## Form Testing
+
+```typescript
+describe('LoginForm', () => {
+  it('should submit valid form', async () => {
+    const user = userEvent.setup()
+    const onSubmit = vi.fn()
+    
+    render(<LoginForm onSubmit={onSubmit} />)
+    
+    await user.type(screen.getByLabelText(/email/i), 'test@example.com')
+    await user.type(screen.getByLabelText(/password/i), 'password123')
+    await user.click(screen.getByRole('button', { name: /sign in/i }))
+    
+    expect(onSubmit).toHaveBeenCalledWith({
+      email: 'test@example.com',
+      password: 'password123',
+    })
+  })
+
+  it('should show validation errors', async () => {
+    const user = userEvent.setup()
+    
+    render(<LoginForm onSubmit={vi.fn()} />)
+    
+    // Submit empty form
+    await user.click(screen.getByRole('button', { name: /sign in/i }))
+    
+    expect(screen.getByText(/email is required/i)).toBeInTheDocument()
+    expect(screen.getByText(/password is required/i)).toBeInTheDocument()
+  })
+
+  it('should validate email format', async () => {
+    const user = userEvent.setup()
+    
+    render(<LoginForm onSubmit={vi.fn()} />)
+    
+    await user.type(screen.getByLabelText(/email/i), 'invalid-email')
+    await user.click(screen.getByRole('button', { name: /sign in/i }))
+    
+    expect(screen.getByText(/invalid email/i)).toBeInTheDocument()
+  })
+
+  it('should disable submit button while submitting', async () => {
+    const user = userEvent.setup()
+    const onSubmit = vi.fn(() => new Promise(resolve => setTimeout(resolve, 100)))
+    
+    render(<LoginForm onSubmit={onSubmit} />)
+    
+    await user.type(screen.getByLabelText(/email/i), 'test@example.com')
+    await user.type(screen.getByLabelText(/password/i), 'password123')
+    await user.click(screen.getByRole('button', { name: /sign in/i }))
+    
+    expect(screen.getByRole('button', { name: /signing in/i })).toBeDisabled()
+    
+    await waitFor(() => {
+      expect(screen.getByRole('button', { name: /sign in/i })).toBeEnabled()
+    })
+  })
+})
+```
+
+## Data-Driven Tests with test.each
+
+```typescript
+describe('StatusBadge', () => {
+  test.each([
+    ['success', 'bg-green-500'],
+    ['warning', 'bg-yellow-500'],
+    ['error', 'bg-red-500'],
+    ['info', 'bg-blue-500'],
+  ])('should apply correct class for %s status', (status, expectedClass) => {
+    render(<StatusBadge status={status} />)
+    
+    expect(screen.getByTestId('status-badge')).toHaveClass(expectedClass)
+  })
+
+  test.each([
+    { input: null, expected: 'Unknown' },
+    { input: undefined, expected: 'Unknown' },
+    { input: '', expected: 'Unknown' },
+    { input: 'invalid', expected: 'Unknown' },
+  ])('should show "Unknown" for invalid input: $input', ({ input, expected }) => {
+    render(<StatusBadge status={input} />)
+    
+    expect(screen.getByText(expected)).toBeInTheDocument()
+  })
+})
+```
+
+## Debugging Tips
+
+```typescript
+// Print entire DOM
+screen.debug()
+
+// Print specific element
+screen.debug(screen.getByRole('button'))
+
+// Log testing playground URL
+screen.logTestingPlaygroundURL()
+
+// Pretty print DOM
+import { prettyDOM } from '@testing-library/react'
+console.log(prettyDOM(screen.getByRole('dialog')))
+
+// Check available roles
+import { getRoles } from '@testing-library/react'
+console.log(getRoles(container))
+```
+
+## Common Mistakes to Avoid
+
+### ❌ Don't Use Implementation Details
+
+```typescript
+// Bad - testing implementation
+expect(component.state.isOpen).toBe(true)
+expect(wrapper.find('.internal-class').length).toBe(1)
+
+// Good - testing behavior
+expect(screen.getByRole('dialog')).toBeInTheDocument()
+```
+
+### ❌ Don't Forget Cleanup
+
+```typescript
+// Bad - may leak state between tests
+it('test 1', () => {
+  render(<Component />)
+})
+
+// Good - cleanup is automatic with RTL, but reset mocks
+beforeEach(() => {
+  vi.clearAllMocks()
+})
+```
+
+### ❌ Don't Use Exact String Matching (Prefer Black-Box Assertions)
+
+```typescript
+// ❌ Bad - hardcoded strings are brittle
+expect(screen.getByText('Submit Form')).toBeInTheDocument()
+expect(screen.getByText('Loading...')).toBeInTheDocument()
+
+// ✅ Good - role-based queries (most semantic)
+expect(screen.getByRole('button', { name: /submit/i })).toBeInTheDocument()
+expect(screen.getByRole('status')).toBeInTheDocument()
+
+// ✅ Good - pattern matching (flexible)
+expect(screen.getByText(/submit/i)).toBeInTheDocument()
+expect(screen.getByText(/loading/i)).toBeInTheDocument()
+
+// ✅ Good - test behavior, not exact UI text
+expect(screen.getByRole('button')).toBeDisabled()
+expect(screen.getByRole('alert')).toBeInTheDocument()
+```
+
+**Why prefer black-box assertions?**
+
+- Text content may change (i18n, copy updates)
+- Role-based queries test accessibility
+- Pattern matching is resilient to minor changes
+- Tests focus on behavior, not implementation details
+
+### ❌ Don't Assert on Absence Without Query
+
+```typescript
+// Bad - throws if not found
+expect(screen.getByText('Error')).not.toBeInTheDocument() // Error!
+
+// Good - use queryBy for absence assertions
+expect(screen.queryByText('Error')).not.toBeInTheDocument()
+```

+
+## ⚠️ Important: What NOT to Mock
+
+### DO NOT Mock Base Components
+
+**Never mock components from `@/app/components/base/`** such as:
+
+- `Loading`, `Spinner`
+- `Button`, `Input`, `Select`
+- `Tooltip`, `Modal`, `Dropdown`
+- `Icon`, `Badge`, `Tag`
+
+**Why?**
+
+- Base components will have their own dedicated tests
+- Mocking them creates false positives (tests pass but real integration fails)
+- Using real components tests actual integration behavior
+
+```typescript
+// ❌ WRONG: Don't mock base components
+vi.mock('@/app/components/base/loading', () => () => <div>Loading</div>)
+vi.mock('@/app/components/base/button', () => ({ children }: any) => <button>{children}</button>)
+
+// ✅ CORRECT: Import and use real base components
+import Loading from '@/app/components/base/loading'
+import Button from '@/app/components/base/button'
+// They will render normally in tests
+```
+
+### What TO Mock
+
+Only mock these categories:
+
+1. **API services** (`@/service/*`) - Network calls
+1. **Complex context providers** - When setup is too difficult
+1. **Third-party libraries with side effects** - `next/navigation`, external SDKs
+1. **i18n** - Always mock to return keys
+
+## Mock Placement
+
+| Location | Purpose |
+|----------|---------|
+| `web/vitest.setup.ts` | Global mocks shared by all tests (for example `react-i18next`, `next/image`) |
+| `web/__mocks__/` | Reusable mock factories shared across multiple test files |
+| Test file | Test-specific mocks, inline with `vi.mock()` |
+
+Modules are not mocked automatically. Use `vi.mock` in test files, or add global mocks in `web/vitest.setup.ts`.
+
+## Essential Mocks
+
+### 1. i18n (Auto-loaded via Global Mock)
+
+A global mock is defined in `web/vitest.setup.ts` and is auto-loaded by Vitest setup.
+**No explicit mock needed** for most tests - it returns translation keys as-is.
+
+For tests requiring custom translations, override the mock:
+
+```typescript
+vi.mock('react-i18next', () => ({
+  useTranslation: () => ({
+    t: (key: string) => {
+      const translations: Record<string, string> = {
+        'my.custom.key': 'Custom translation',
+      }
+      return translations[key] || key
+    },
+  }),
+}))
+```
+
+### 2. Next.js Router
+
+```typescript
+const mockPush = vi.fn()
+const mockReplace = vi.fn()
+
+vi.mock('next/navigation', () => ({
+  useRouter: () => ({
+    push: mockPush,
+    replace: mockReplace,
+    back: vi.fn(),
+    prefetch: vi.fn(),
+  }),
+  usePathname: () => '/current-path',
+  useSearchParams: () => new URLSearchParams('?key=value'),
+}))
+
+describe('Component', () => {
+  beforeEach(() => {
+    vi.clearAllMocks()
+  })
+
+  it('should navigate on click', () => {
+    render(<Component />)
+    fireEvent.click(screen.getByRole('button'))
+    expect(mockPush).toHaveBeenCalledWith('/expected-path')
+  })
+})
+```
+
+### 3. Portal Components (with Shared State)
+
+```typescript
+// ⚠️ Important: Use shared state for components that depend on each other
+let mockPortalOpenState = false
+
+vi.mock('@/app/components/base/portal-to-follow-elem', () => ({
+  PortalToFollowElem: ({ children, open, ...props }: any) => {
+    mockPortalOpenState = open || false  // Update shared state
+    return <div data-testid="portal" data-open={open}>{children}</div>
+  },
+  PortalToFollowElemContent: ({ children }: any) => {
+    // ✅ Matches actual: returns null when portal is closed
+    if (!mockPortalOpenState) return null
+    return <div data-testid="portal-content">{children}</div>
+  },
+  PortalToFollowElemTrigger: ({ children }: any) => (
+    <div data-testid="portal-trigger">{children}</div>
+  ),
+}))
+
+describe('Component', () => {
+  beforeEach(() => {
+    vi.clearAllMocks()
+    mockPortalOpenState = false  // ✅ Reset shared state
+  })
+})
+```
+
+### 4. API Service Mocks
+
+```typescript
+import * as api from '@/service/api'
+
+vi.mock('@/service/api')
+
+const mockedApi = vi.mocked(api)
+
+describe('Component', () => {
+  beforeEach(() => {
+    vi.clearAllMocks()
+    
+    // Setup default mock implementation
+    mockedApi.fetchData.mockResolvedValue({ data: [] })
+  })
+
+  it('should show data on success', async () => {
+    mockedApi.fetchData.mockResolvedValue({ data: [{ id: 1 }] })
+    
+    render(<Component />)
+    
+    await waitFor(() => {
+      expect(screen.getByText('1')).toBeInTheDocument()
+    })
+  })
+
+  it('should show error on failure', async () => {
+    mockedApi.fetchData.mockRejectedValue(new Error('Network error'))
+    
+    render(<Component />)
+    
+    await waitFor(() => {
+      expect(screen.getByText(/error/i)).toBeInTheDocument()
+    })
+  })
+})
+```
+
+### 5. HTTP Mocking with Nock
+
+```typescript
+import nock from 'nock'
+
+const GITHUB_HOST = 'https://api.github.com'
+const GITHUB_PATH = '/repos/owner/repo'
+
+const mockGithubApi = (status: number, body: Record<string, unknown>, delayMs = 0) => {
+  return nock(GITHUB_HOST)
+    .get(GITHUB_PATH)
+    .delay(delayMs)
+    .reply(status, body)
+}
+
+describe('GithubComponent', () => {
+  afterEach(() => {
+    nock.cleanAll()
+  })
+
+  it('should display repo info', async () => {
+    mockGithubApi(200, { name: 'dify', stars: 1000 })
+    
+    render(<GithubComponent />)
+    
+    await waitFor(() => {
+      expect(screen.getByText('dify')).toBeInTheDocument()
+    })
+  })
+
+  it('should handle API error', async () => {
+    mockGithubApi(500, { message: 'Server error' })
+    
+    render(<GithubComponent />)
+    
+    await waitFor(() => {
+      expect(screen.getByText(/error/i)).toBeInTheDocument()
+    })
+  })
+})
+```
+
+### 6. Context Providers
+
+```typescript
+import { ProviderContext } from '@/context/provider-context'
+import { createMockProviderContextValue, createMockPlan } from '@/__mocks__/provider-context'
+
+describe('Component with Context', () => {
+  it('should render for free plan', () => {
+    const mockContext = createMockPlan('sandbox')
+    
+    render(
+      <ProviderContext.Provider value={mockContext}>
+        <Component />
+      </ProviderContext.Provider>
+    )
+    
+    expect(screen.getByText('Upgrade')).toBeInTheDocument()
+  })
+
+  it('should render for pro plan', () => {
+    const mockContext = createMockPlan('professional')
+    
+    render(
+      <ProviderContext.Provider value={mockContext}>
+        <Component />
+      </ProviderContext.Provider>
+    )
+    
+    expect(screen.queryByText('Upgrade')).not.toBeInTheDocument()
+  })
+})
+```
+
+### 7. React Query
+
+```typescript
+import { QueryClient, QueryClientProvider } from '@tanstack/react-query'
+
+const createTestQueryClient = () => new QueryClient({
+  defaultOptions: {
+    queries: { retry: false },
+    mutations: { retry: false },
+  },
+})
+
+const renderWithQueryClient = (ui: React.ReactElement) => {
+  const queryClient = createTestQueryClient()
+  return render(
+    <QueryClientProvider client={queryClient}>
+      {ui}
+    </QueryClientProvider>
+  )
+}
+```
+
+## Mock Best Practices
+
+### ✅ DO
+
+1. **Use real base components** - Import from `@/app/components/base/` directly
+1. **Use real project components** - Prefer importing over mocking
+1. **Reset mocks in `beforeEach`**, not `afterEach`
+1. **Match actual component behavior** in mocks (when mocking is necessary)
+1. **Use factory functions** for complex mock data
+1. **Import actual types** for type safety
+1. **Reset shared mock state** in `beforeEach`
+
+### ❌ DON'T
+
+1. **Don't mock base components** (`Loading`, `Button`, `Tooltip`, etc.)
+1. Don't mock components you can import directly
+1. Don't create overly simplified mocks that miss conditional logic
+1. Don't forget to clean up nock after each test
+1. Don't use `any` types in mocks without necessity
+
+### Mock Decision Tree
+
+```
+Need to use a component in test?
+│
+├─ Is it from @/app/components/base/*?
+│  └─ YES → Import real component, DO NOT mock
+│
+├─ Is it a project component?
+│  └─ YES → Prefer importing real component
+│           Only mock if setup is extremely complex
+│
+├─ Is it an API service (@/service/*)?
+│  └─ YES → Mock it
+│
+├─ Is it a third-party lib with side effects?
+│  └─ YES → Mock it (next/navigation, external SDKs)
+│
+└─ Is it i18n?
+   └─ YES → Uses shared mock (auto-loaded). Override only for custom translations
+```
+
+## Factory Function Pattern
+
+```typescript
+// __mocks__/data-factories.ts
+import type { User, Project } from '@/types'
+
+export const createMockUser = (overrides: Partial<User> = {}): User => ({
+  id: 'user-1',
+  name: 'Test User',
+  email: 'test@example.com',
+  role: 'member',
+  createdAt: new Date().toISOString(),
+  ...overrides,
+})
+
+export const createMockProject = (overrides: Partial<Project> = {}): Project => ({
+  id: 'project-1',
+  name: 'Test Project',
+  description: 'A test project',
+  owner: createMockUser(),
+  members: [],
+  createdAt: new Date().toISOString(),
+  ...overrides,
+})
+
+// Usage in tests
+it('should display project owner', () => {
+  const project = createMockProject({
+    owner: createMockUser({ name: 'John Doe' }),
+  })
+  
+  render(<ProjectCard project={project} />)
+  expect(screen.getByText('John Doe')).toBeInTheDocument()
+})
+```

+# Testing Workflow Guide
+
+This guide defines the workflow for generating tests, especially for complex components or directories with multiple files.
+
+## Scope Clarification
+
+This guide addresses **multi-file workflow** (how to process multiple test files). For coverage requirements within a single test file, see `web/testing/testing.md` § Coverage Goals.
+
+| Scope | Rule |
+|-------|------|
+| **Single file** | Complete coverage in one generation (100% function, >95% branch) |
+| **Multi-file directory** | Process one file at a time, verify each before proceeding |
+
+## ⚠️ Critical Rule: Incremental Approach for Multi-File Testing
+
+When testing a **directory with multiple files**, **NEVER generate all test files at once.** Use an incremental, verify-as-you-go approach.
+
+### Why Incremental?
+
+| Batch Approach (❌) | Incremental Approach (✅) |
+|---------------------|---------------------------|
+| Generate 5+ tests at once | Generate 1 test at a time |
+| Run tests only at the end | Run test immediately after each file |
+| Multiple failures compound | Single point of failure, easy to debug |
+| Hard to identify root cause | Clear cause-effect relationship |
+| Mock issues affect many files | Mock issues caught early |
+| Messy git history | Clean, atomic commits possible |
+
+## Single File Workflow
+
+When testing a **single component, hook, or utility**:
+
+```
+1. Read source code completely
+2. Run `pnpm analyze-component <path>` (if available)
+3. Check complexity score and features detected
+4. Write the test file
+5. Run test: `pnpm test <file>.spec.tsx`
+6. Fix any failures
+7. Verify coverage meets goals (100% function, >95% branch)
+```
+
+## Directory/Multi-File Workflow (MUST FOLLOW)
+
+When testing a **directory or multiple files**, follow this strict workflow:
+
+### Step 1: Analyze and Plan
+
+1. **List all files** that need tests in the directory
+1. **Categorize by complexity**:
+   - 🟢 **Simple**: Utility functions, simple hooks, presentational components
+   - 🟡 **Medium**: Components with state, effects, or event handlers
+   - 🔴 **Complex**: Components with API calls, routing, or many dependencies
+1. **Order by dependency**: Test dependencies before dependents
+1. **Create a todo list** to track progress
+
+### Step 2: Determine Processing Order
+
+Process files in this recommended order:
+
+```
+1. Utility functions (simplest, no React)
+2. Custom hooks (isolated logic)
+3. Simple presentational components (few/no props)
+4. Medium complexity components (state, effects)
+5. Complex components (API, routing, many deps)
+6. Container/index components (integration tests - last)
+```
+
+**Rationale**:
+
+- Simpler files help establish mock patterns
+- Hooks used by components should be tested first
+- Integration tests (index files) depend on child components working
+
+### Step 3: Process Each File Incrementally
+
+**For EACH file in the ordered list:**
+
+```
+┌─────────────────────────────────────────────┐
+│  1. Write test file                         │
+│  2. Run: pnpm test <file>.spec.tsx          │
+│  3. If FAIL → Fix immediately, re-run       │
+│  4. If PASS → Mark complete in todo list    │
+│  5. ONLY THEN proceed to next file          │
+└─────────────────────────────────────────────┘
+```
+
+**DO NOT proceed to the next file until the current one passes.**
+
+### Step 4: Final Verification
+
+After all individual tests pass:
+
+```bash
+# Run all tests in the directory together
+pnpm test path/to/directory/
+
+# Check coverage
+pnpm test:coverage path/to/directory/
+```
+
+## Component Complexity Guidelines
+
+Use `pnpm analyze-component <path>` to assess complexity before testing.
+
+### 🔴 Very Complex Components (Complexity > 50)
+
+**Consider refactoring BEFORE testing:**
+
+- Break component into smaller, testable pieces
+- Extract complex logic into custom hooks
+- Separate container and presentational layers
+
+**If testing as-is:**
+
+- Use integration tests for complex workflows
+- Use `test.each()` for data-driven testing
+- Multiple `describe` blocks for organization
+- Consider testing major sections separately
+
+### 🟡 Medium Complexity (Complexity 30-50)
+
+- Group related tests in `describe` blocks
+- Test integration scenarios between internal parts
+- Focus on state transitions and side effects
+- Use helper functions to reduce test complexity
+
+### 🟢 Simple Components (Complexity < 30)
+
+- Standard test structure
+- Focus on props, rendering, and edge cases
+- Usually straightforward to test
+
+### 📏 Large Files (500+ lines)
+
+Regardless of complexity score:
+
+- **Strongly consider refactoring** before testing
+- If testing as-is, test major sections separately
+- Create helper functions for test setup
+- May need multiple test files
+
+## Todo List Format
+
+When testing multiple files, use a todo list like this:
+
+```
+Testing: path/to/directory/
+
+Ordered by complexity (simple → complex):
+
+☐ utils/helper.ts           [utility, simple]
+☐ hooks/use-custom-hook.ts  [hook, simple]
+☐ empty-state.tsx           [component, simple]
+☐ item-card.tsx             [component, medium]
+☐ list.tsx                  [component, complex]
+☐ index.tsx                 [integration]
+
+Progress: 0/6 complete
+```
+
+Update status as you complete each:
+
+- ☐ → ⏳ (in progress)
+- ⏳ → ✅ (complete and verified)
+- ⏳ → ❌ (blocked, needs attention)
+
+## When to Stop and Verify
+
+**Always run tests after:**
+
+- Completing a test file
+- Making changes to fix a failure
+- Modifying shared mocks
+- Updating test utilities or helpers
+
+**Signs you should pause:**
+
+- More than 2 consecutive test failures
+- Mock-related errors appearing
+- Unclear why a test is failing
+- Test passing but coverage unexpectedly low
+
+## Common Pitfalls to Avoid
+
+### ❌ Don't: Generate Everything First
+
+```
+# BAD: Writing all files then testing
+Write component-a.spec.tsx
+Write component-b.spec.tsx  
+Write component-c.spec.tsx
+Write component-d.spec.tsx
+Run pnpm test  ← Multiple failures, hard to debug
+```
+
+### ✅ Do: Verify Each Step
+
+```
+# GOOD: Incremental with verification
+Write component-a.spec.tsx
+Run pnpm test component-a.spec.tsx ✅
+Write component-b.spec.tsx
+Run pnpm test component-b.spec.tsx ✅
+...continue...
+```
+
+### ❌ Don't: Skip Verification for "Simple" Components
+
+Even simple components can have:
+
+- Import errors
+- Missing mock setup
+- Incorrect assumptions about props
+
+**Always verify, regardless of perceived simplicity.**
+
+### ❌ Don't: Continue When Tests Fail
+
+Failing tests compound:
+
+- A mock issue in file A affects files B, C, D
+- Fixing A later requires revisiting all dependent tests
+- Time wasted on debugging cascading failures
+
+**Fix failures immediately before proceeding.**
+
+## Integration with Claude's Todo Feature
+
+When using Claude for multi-file testing:
+
+1. **Ask Claude to create a todo list** before starting
+1. **Request one file at a time** or ensure Claude processes incrementally
+1. **Verify each test passes** before asking for the next
+1. **Mark todos complete** as you progress
+
+Example prompt:
+
+```
+Test all components in `path/to/directory/`.
+First, analyze the directory and create a todo list ordered by complexity.
+Then, process ONE file at a time, waiting for my confirmation that tests pass
+before proceeding to the next.
+```
+
+## Summary Checklist

+
+## Project Overview
+
+Dify is an open-source platform for developing LLM applications with an intuitive interface combining agentic AI workflows, RAG pipelines, agent capabilities, and model management.
+
+The codebase is split into:
+
+- **Backend API** (`/api`): Python Flask application organized with Domain-Driven Design
+- **Frontend Web** (`/web`): Next.js 15 application using TypeScript and React 19
+- **Docker deployment** (`/docker`): Containerized deployment configurations
+
+## Backend Workflow
+
+- Run backend CLI commands through `uv run --project api <command>`.
+
+- Before submission, all backend modifications must pass local checks: `make lint`, `make type-check`, and `uv run --project api --dev dev/pytest/pytest_unit_tests.sh`.
+
+- Use Makefile targets for linting and formatting; `make lint` and `make type-check` cover the required checks.
+
+- Integration tests are CI-only and are not expected to run in the local environment.
+
+## Frontend Workflow
+
+```bash
+cd web
+pnpm lint:fix
+pnpm type-check:tsgo
+pnpm test
+```
+
+## Testing & Quality Practices
+
+- Follow TDD: red → green → refactor.
+- Use `pytest` for backend tests with Arrange-Act-Assert structure.
+- Enforce strong typing; avoid `Any` and prefer explicit type annotations.
+- Write self-documenting code; only add comments that explain intent.
+
+## Language Style
+
+- **Python**: Keep type hints on functions and attributes, and implement relevant special methods (e.g., `__repr__`, `__str__`).
+- **TypeScript**: Use the strict config, rely on ESLint (`pnpm lint:fix` preferred) plus `pnpm type-check:tsgo`, and avoid `any` types.
+
+## General Practices
+
+- Prefer editing existing files; add new documentation only when requested.
+- Inject dependencies through constructors and preserve clean architecture boundaries.
+- Handle errors with domain-specific exceptions at the correct layer.
+
+## Project Conventions
+
+- Backend architecture adheres to DDD and Clean Architecture principles.
+- Async work runs through Celery with Redis as the broker.
+- Frontend user-facing strings must use `web/i18n/en-US/`; avoid hardcoded text.

-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-Dify is an open-source platform for developing LLM applications with an intuitive interface combining agentic AI workflows, RAG pipelines, agent capabilities, and model management.
-
-The codebase consists of:
-
-- **Backend API** (`/api`): Python Flask application with Domain-Driven Design architecture
-- **Frontend Web** (`/web`): Next.js 15 application with TypeScript and React 19
-- **Docker deployment** (`/docker`): Containerized deployment configurations
-
-## Development Commands
-
-### Backend (API)
-
-All Python commands must be prefixed with `uv run --project api`:
-
-```bash
-# Start development servers
-./dev/start-api                   # Start API server
-./dev/start-worker                # Start Celery worker
-
-# Run tests
-uv run --project api pytest      # Run all tests
-uv run --project api pytest tests/unit_tests/     # Unit tests only
-uv run --project api pytest tests/integration_tests/  # Integration tests
-
-# Code quality
-./dev/reformat                    # Run all formatters and linters
-uv run --project api ruff check --fix ./    # Fix linting issues
-uv run --project api ruff format ./         # Format code
-uv run --project api mypy .                 # Type checking
-```
-
-### Frontend (Web)
-
-```bash
-cd web
-pnpm lint                         # Run ESLint
-pnpm eslint-fix                   # Fix ESLint issues
-pnpm test                         # Run Jest tests
-```
-
-## Testing Guidelines
-
-### Backend Testing
-
-- Use `pytest` for all backend tests
-- Write tests first (TDD approach)
-- Test structure: Arrange-Act-Assert
-
-## Code Style Requirements
-
-### Python
-
-- Use type hints for all functions and class attributes
-- No `Any` types unless absolutely necessary
-- Implement special methods (`__repr__`, `__str__`) appropriately
-
-### TypeScript/JavaScript
-
-- Strict TypeScript configuration
-- ESLint with Prettier integration
-- Avoid `any` type
-
-## Important Notes
-
-- **Environment Variables**: Always use UV for Python commands: `uv run --project api <command>`
-- **Comments**: Only write meaningful comments that explain "why", not "what"
-- **File Creation**: Always prefer editing existing files over creating new ones
-- **Documentation**: Don't create documentation files unless explicitly requested
-- **Code Quality**: Always run `./dev/reformat` before committing backend changes
-
-## Common Development Tasks
-
-### Adding a New API Endpoint
-
-1. Create controller in `/api/controllers/`
-1. Add service logic in `/api/services/`
-1. Update routes in controller's `__init__.py`
-1. Write tests in `/api/tests/`
-
-## Project-Specific Conventions
-
-- All async tasks use Celery with Redis as broker

 ## Advanced Setup
 
+### Custom configurations
+
 If you need to customize the configuration, please refer to the comments in our [.env.example](docker/.env.example) file and update the corresponding values in your `.env` file. Additionally, you might need to make adjustments to the `docker-compose.yaml` file itself, such as changing image versions, port mappings, or volume mounts, based on your specific deployment environment and requirements. After making any changes, please re-run `docker-compose up -d`. You can find the full list of available environment variables [here](https://docs.dify.ai/getting-started/install-self-hosted/environments).
 
+#### Customizing Suggested Questions
+
+You can now customize the "Suggested Questions After Answer" feature to better fit your use case. For example, to generate longer, more technical questions:
+
+```bash
+# In your .env file
+SUGGESTED_QUESTIONS_PROMPT='Please help me predict the five most likely technical follow-up questions a developer would ask. Focus on implementation details, best practices, and architecture considerations. Keep each question between 40-60 characters. Output must be JSON array: ["question1","question2","question3","question4","question5"]'
+SUGGESTED_QUESTIONS_MAX_TOKENS=512
+SUGGESTED_QUESTIONS_TEMPERATURE=0.3

+
+See the [Suggested Questions Configuration Guide](docs/suggested-questions-configuration.md) for detailed examples and usage instructions.

+# Agent Skill Index
+
+Start with the section that best matches your need. Each entry lists the problems it solves plus key files/concepts so you know what to expect before opening it.
+
+______________________________________________________________________
+
+## Platform Foundations
+
+- **[Infrastructure Overview](agent_skills/infra.md)**\
+  When to read this:
+
+  - You need to understand where a feature belongs in the architecture.
+  - You’re wiring storage, Redis, vector stores, or OTEL.
+  - You’re about to add CLI commands or async jobs.\
+    What it covers: configuration stack (`configs/app_config.py`, remote settings), storage entry points (`extensions/ext_storage.py`, `core/file/file_manager.py`), Redis conventions (`extensions/ext_redis.py`), plugin runtime topology, vector-store factory (`core/rag/datasource/vdb/*`), observability hooks, SSRF proxy usage, and core CLI commands.
+
+- **[Coding Style](agent_skills/coding_style.md)**\
+  When to read this:
+
+  - You’re writing or reviewing backend code and need the authoritative checklist.
+  - You’re unsure about Pydantic validators, SQLAlchemy session usage, or logging patterns.
+  - You want the exact lint/type/test commands used in PRs.\
+    Includes: Ruff & BasedPyright commands, no-annotation policy, session examples (`with Session(db.engine, ...)`), `@field_validator` usage, logging expectations, and the rule set for file size, helpers, and package management.
+
+______________________________________________________________________
+
+## Plugin & Extension Development
+
+- **[Plugin Systems](agent_skills/plugin.md)**\
+  When to read this:
+
+  - You’re building or debugging a marketplace plugin.
+  - You need to know how manifests, providers, daemons, and migrations fit together.\
+    What it covers: plugin manifests (`core/plugin/entities/plugin.py`), installation/upgrade flows (`services/plugin/plugin_service.py`, CLI commands), runtime adapters (`core/plugin/impl/*` for tool/model/datasource/trigger/endpoint/agent), daemon coordination (`core/plugin/entities/plugin_daemon.py`), and how provider registries surface capabilities to the rest of the platform.
+
+- **[Plugin OAuth](agent_skills/plugin_oauth.md)**\
+  When to read this:
+
+  - You must integrate OAuth for a plugin or datasource.
+  - You’re handling credential encryption or refresh flows.\
+    Topics: credential storage, encryption helpers (`core/helper/provider_encryption.py`), OAuth client bootstrap (`services/plugin/oauth_service.py`, `services/plugin/plugin_parameter_service.py`), and how console/API layers expose the flows.
+
+______________________________________________________________________
+
+## Workflow Entry & Execution
+
+- **[Trigger Concepts](agent_skills/trigger.md)**\
+  When to read this:
+  - You’re debugging why a workflow didn’t start.
+  - You’re adding a new trigger type or hook.
+  - You need to trace async execution, draft debugging, or webhook/schedule pipelines.\
+    Details: Start-node taxonomy, webhook & schedule internals (`core/workflow/nodes/trigger_*`, `services/trigger/*`), async orchestration (`services/async_workflow_service.py`, Celery queues), debug event bus, and storage/logging interactions.
+
+______________________________________________________________________
+
+## Additional Notes for Agents
+
+- All skill docs assume you follow the coding style guide—run Ruff/BasedPyright/tests listed there before submitting changes.
+- When you cannot find an answer in these briefs, search the codebase using the paths referenced (e.g., `core/plugin/impl/tool.py`, `services/dataset_service.py`).
+- If you run into cross-cutting concerns (tenancy, configuration, storage), check the infrastructure guide first; it links to most supporting modules.
+- Keep multi-tenancy and configuration central: everything flows through `configs.dify_config` and `tenant_id`.
+- When touching plugins or triggers, consult both the system overview and the specialised doc to ensure you adjust lifecycle, storage, and observability consistently.

+## Linter
+
+- Always follow `.ruff.toml`.
+- Run `uv run ruff check --fix --unsafe-fixes`.
+- Keep each line under 100 characters (including spaces).
+
+## Code Style
+
+- `snake_case` for variables and functions.
+- `PascalCase` for classes.
+- `UPPER_CASE` for constants.
+
+## Rules
+
+- Use Pydantic v2 standard.
+- Use `uv` for package management.
+- Do not override dunder methods like `__init__`, `__iadd__`, etc.
+- Never launch services (`uv run app.py`, `flask run`, etc.); running tests under `tests/` is allowed.
+- Prefer simple functions over classes for lightweight helpers.
+- Keep files below 800 lines; split when necessary.
+- Keep code readable—no clever hacks.
+- Never use `print`; log with `logger = logging.getLogger(__name__)`.
+
+## Guiding Principles
+
+- Mirror the project’s layered architecture: controller → service → core/domain.
+- Reuse existing helpers in `core/`, `services/`, and `libs/` before creating new abstractions.
+- Optimise for observability: deterministic control flow, clear logging, actionable errors.
+
+## SQLAlchemy Patterns
+
+- Models inherit from `models.base.Base`; never create ad-hoc metadata or engines.
+
+- Open sessions with context managers:
+
+  ```python
+  from sqlalchemy.orm import Session
+
+  with Session(db.engine, expire_on_commit=False) as session:
+      stmt = select(Workflow).where(
+          Workflow.id == workflow_id,
+          Workflow.tenant_id == tenant_id,
+      )
+      workflow = session.execute(stmt).scalar_one_or_none()
+  ```
+
+- Use SQLAlchemy expressions; avoid raw SQL unless necessary.
+
+- Introduce repository abstractions only for very large tables (e.g., workflow executions) to support alternative storage strategies.
+
+- Always scope queries by `tenant_id` and protect write paths with safeguards (`FOR UPDATE`, row counts, etc.).
+
+## Storage & External IO
+
+- Access storage via `extensions.ext_storage.storage`.
+- Use `core.helper.ssrf_proxy` for outbound HTTP fetches.
+- Background tasks that touch storage must be idempotent and log the relevant object identifiers.
+
+## Pydantic Usage
+
+- Define DTOs with Pydantic v2 models and forbid extras by default.
+
+- Use `@field_validator` / `@model_validator` for domain rules.
+
+- Example:
+
+  ```python
+  from pydantic import BaseModel, ConfigDict, HttpUrl, field_validator
+
+  class TriggerConfig(BaseModel):
+      endpoint: HttpUrl
+      secret: str
+
+      model_config = ConfigDict(extra="forbid")
+
+      @field_validator("secret")
+      def ensure_secret_prefix(cls, value: str) -> str:
+          if not value.startswith("dify_"):
+              raise ValueError("secret must start with dify_")
+          return value
+  ```
+
+## Generics & Protocols
+
+- Use `typing.Protocol` to define behavioural contracts (e.g., cache interfaces).
+- Apply generics (`TypeVar`, `Generic`) for reusable utilities like caches or providers.
+- Validate dynamic inputs at runtime when generics cannot enforce safety alone.
+
+## Error Handling & Logging
+
+- Raise domain-specific exceptions (`services/errors`, `core/errors`) and translate to HTTP responses in controllers.
+- Declare `logger = logging.getLogger(__name__)` at module top.
+- Include tenant/app/workflow identifiers in log context.
+- Log retryable events at `warning`, terminal failures at `error`.
+
+## Tooling & Checks
+
+- Format/lint: `uv run --project api --dev ruff format ./api` and `uv run --project api --dev ruff check --fix --unsafe-fixes ./api`.
+- Type checks: `uv run --directory api --dev basedpyright`.
+- Tests: `uv run --project api --dev dev/pytest/pytest_unit_tests.sh`.
+- Run all of the above before submitting your work.
+
+## Controllers & Services
+
+- Controllers: parse input via Pydantic, invoke services, return serialised responses; no business logic.
+- Services: coordinate repositories, providers, background tasks; keep side effects explicit.
+- Avoid repositories unless necessary; direct SQLAlchemy usage is preferred for typical tables.
+- Document non-obvious behaviour with concise comments.
+
+## Miscellaneous
+
+- Use `configs.dify_config` for configuration—never read environment variables directly.
+- Maintain tenant awareness end-to-end; `tenant_id` must flow through every layer touching shared resources.
+- Queue async work through `services/async_workflow_service`; implement tasks under `tasks/` with explicit queue selection.
+- Keep experimental scripts under `dev/`; do not ship them in production builds.

api/agent_skills/infra.md

@@ -0,0 +1,96 @@
+## Configuration
+
+- Import `configs.dify_config` for every runtime toggle. Do not read environment variables directly.
+- Add new settings to the proper mixin inside `configs/` (deployment, feature, middleware, etc.) so they load through `DifyConfig`.
+- Remote overrides come from the optional providers in `configs/remote_settings_sources`; keep defaults in code safe when the value is missing.
+- Example: logging pulls targets from `extensions/ext_logging.py`, and model provider URLs are assembled in `services/entities/model_provider_entities.py`.
+
+## Dependencies
+
+- Runtime dependencies live in `[project].dependencies` inside `pyproject.toml`. Optional clients go into the `storage`, `tools`, or `vdb` groups under `[dependency-groups]`.
+- Always pin versions and keep the list alphabetised. Shared tooling (lint, typing, pytest) belongs in the `dev` group.
+- When code needs a new package, explain why in the PR and run `uv lock` so the lockfile stays current.
+
+## Storage & Files
+
+- Use `extensions.ext_storage.storage` for all blob IO; it already respects the configured backend.
+- Convert files for workflows with helpers in `core/file/file_manager.py`; they handle signed URLs and multimodal payloads.
+- When writing controller logic, delegate upload quotas and metadata to `services/file_service.py` instead of touching storage directly.
+- All outbound HTTP fetches (webhooks, remote files) must go through the SSRF-safe client in `core/helper/ssrf_proxy.py`; it wraps `httpx` with the allow/deny rules configured for the platform.
+
+## Redis & Shared State
+
+- Access Redis through `extensions.ext_redis.redis_client`. For locking, reuse `redis_client.lock`.
+- Prefer higher-level helpers when available: rate limits use `libs.helper.RateLimiter`, provider metadata uses caches in `core/helper/provider_cache.py`.
+
+## Models
+
+- SQLAlchemy models sit in `models/` and inherit from the shared declarative `Base` defined in `models/base.py` (metadata configured via `models/engine.py`).
+- `models/__init__.py` exposes grouped aggregates: account/tenant models, app and conversation tables, datasets, providers, workflow runs, triggers, etc. Import from there to avoid deep path churn.
+- Follow the DDD boundary: persistence objects live in `models/`, repositories under `repositories/` translate them into domain entities, and services consume those repositories.
+- When adding a table, create the model class, register it in `models/__init__.py`, wire a repository if needed, and generate an Alembic migration as described below.
+
+## Vector Stores
+
+- Vector client implementations live in `core/rag/datasource/vdb/<provider>`, with a common factory in `core/rag/datasource/vdb/vector_factory.py` and enums in `core/rag/datasource/vdb/vector_type.py`.
+- Retrieval pipelines call these providers through `core/rag/datasource/retrieval_service.py` and dataset ingestion flows in `services/dataset_service.py`.
+- The CLI helper `flask vdb-migrate` orchestrates bulk migrations using routines in `commands.py`; reuse that pattern when adding new backend transitions.
+- To add another store, mirror the provider layout, register it with the factory, and include any schema changes in Alembic migrations.
+
+## Observability & OTEL
+
+- OpenTelemetry settings live under the observability mixin in `configs/observability`. Toggle exporters and sampling via `dify_config`, not ad-hoc env reads.
+- HTTP, Celery, Redis, SQLAlchemy, and httpx instrumentation is initialised in `extensions/ext_app_metrics.py` and `extensions/ext_request_logging.py`; reuse these hooks when adding new workers or entrypoints.
+- When creating background tasks or external calls, propagate tracing context with helpers in the existing instrumented clients (e.g. use the shared `httpx` session from `core/helper/http_client_pooling.py`).
+- If you add a new external integration, ensure spans and metrics are emitted by wiring the appropriate OTEL instrumentation package in `pyproject.toml` and configuring it in `extensions/`.
+
+## Ops Integrations
+
+- Langfuse support and other tracing bridges live under `core/ops/opik_trace`. Config toggles sit in `configs/observability`, while exporters are initialised in the OTEL extensions mentioned above.
+- External monitoring services should follow this pattern: keep client code in `core/ops`, expose switches via `dify_config`, and hook initialisation in `extensions/ext_app_metrics.py` or sibling modules.
+- Before instrumenting new code paths, check whether existing context helpers (e.g. `extensions/ext_request_logging.py`) already capture the necessary metadata.
+
+## Controllers, Services, Core
+
+- Controllers only parse HTTP input and call a service method. Keep business rules in `services/`.
+- Services enforce tenant rules, quotas, and orchestration, then call into `core/` engines (workflow execution, tools, LLMs).
+- When adding a new endpoint, search for an existing service to extend before introducing a new layer. Example: workflow APIs pipe through `services/workflow_service.py` into `core/workflow`.
+
+## Plugins, Tools, Providers
+
+- In Dify a plugin is a tenant-installable bundle that declares one or more providers (tool, model, datasource, trigger, endpoint, agent strategy) plus its resource needs and version metadata. The manifest (`core/plugin/entities/plugin.py`) mirrors what you see in the marketplace documentation.
+- Installation, upgrades, and migrations are orchestrated by `services/plugin/plugin_service.py` together with helpers such as `services/plugin/plugin_migration.py`.
+- Runtime loading happens through the implementations under `core/plugin/impl/*` (tool/model/datasource/trigger/endpoint/agent). These modules normalise plugin providers so that downstream systems (`core/tools/tool_manager.py`, `services/model_provider_service.py`, `services/trigger/*`) can treat builtin and plugin capabilities the same way.
+- For remote execution, plugin daemons (`core/plugin/entities/plugin_daemon.py`, `core/plugin/impl/plugin.py`) manage lifecycle hooks, credential forwarding, and background workers that keep plugin processes in sync with the main application.
+- Acquire tool implementations through `core/tools/tool_manager.py`; it resolves builtin, plugin, and workflow-as-tool providers uniformly, injecting the right context (tenant, credentials, runtime config).
+- To add a new plugin capability, extend the relevant `core/plugin/entities` schema and register the implementation in the matching `core/plugin/impl` module rather than importing the provider directly.
+
+## Async Workloads
+
+see `agent_skills/trigger.md` for more detailed documentation.
+
+- Enqueue background work through `services/async_workflow_service.py`. It routes jobs to the tiered Celery queues defined in `tasks/`.
+- Workers boot from `celery_entrypoint.py` and execute functions in `tasks/workflow_execution_tasks.py`, `tasks/trigger_processing_tasks.py`, etc.
+- Scheduled workflows poll from `schedule/workflow_schedule_tasks.py`. Follow the same pattern if you need new periodic jobs.
+
+## Database & Migrations
+
+- SQLAlchemy models live under `models/` and map directly to migration files in `migrations/versions`.
+- Generate migrations with `uv run --project api flask db revision --autogenerate -m "<summary>"`, then review the diff; never hand-edit the database outside Alembic.
+- Apply migrations locally using `uv run --project api flask db upgrade`; production deploys expect the same history.
+- If you add tenant-scoped data, confirm the upgrade includes tenant filters or defaults consistent with the service logic touching those tables.
+
+## CLI Commands
+
+- Maintenance commands from `commands.py` are registered on the Flask CLI. Run them via `uv run --project api flask <command>`.
+- Use the built-in `db` commands from Flask-Migrate for schema operations (`flask db upgrade`, `flask db stamp`, etc.). Only fall back to custom helpers if you need their extra behaviour.
+- Custom entries such as `flask reset-password`, `flask reset-email`, and `flask vdb-migrate` handle self-hosted account recovery and vector database migrations.
+- Before adding a new command, check whether an existing service can be reused and ensure the command guards edition-specific behaviour (many enforce `SELF_HOSTED`). Document any additions in the PR.
+- Ruff helpers are run directly with `uv`: `uv run --project api --dev ruff format ./api` for formatting and `uv run --project api --dev ruff check ./api` (add `--fix` if you want automatic fixes).
+
+## When You Add Features
+
+- Check for an existing helper or service before writing a new util.

+## Overview
+
+Trigger is a collection of nodes that we called `Start` nodes, also, the concept of `Start` is the same as `RootNode` in the workflow engine `core/workflow/graph_engine`, On the other hand, `Start` node is the entry point of workflows, every workflow run always starts from a `Start` node.
+
+## Trigger nodes
+
+- `UserInput`
+- `Trigger Webhook`
+- `Trigger Schedule`
+- `Trigger Plugin`
+
+### UserInput
+
+Before `Trigger` concept is introduced, it's what we called `Start` node, but now, to avoid confusion, it was renamed to `UserInput` node, has a strong relation with `ServiceAPI` in `controllers/service_api/app`
+
+1. `UserInput` node introduces a list of arguments that need to be provided by the user, finally it will be converted into variables in the workflow variable pool.
+1. `ServiceAPI` accept those arguments, and pass through them into `UserInput` node.
+1. For its detailed implementation, please refer to `core/workflow/nodes/start`
+
+### Trigger Webhook
+
+Inside Webhook Node, Dify provided a UI panel that allows user define a HTTP manifest `core/workflow/nodes/trigger_webhook/entities.py`.`WebhookData`, also, Dify generates a random webhook id for each `Trigger Webhook` node, the implementation was implemented in `core/trigger/utils/endpoint.py`, as you can see, `webhook-debug` is a debug mode for webhook, you may find it in `controllers/trigger/webhook.py`.
+
+Finally, requests to `webhook` endpoint will be converted into variables in workflow variable pool during workflow execution.
+
+### Trigger Schedule
+
+`Trigger Schedule` node is a node that allows user define a schedule to trigger the workflow, detailed manifest is here `core/workflow/nodes/trigger_schedule/entities.py`, we have a poller and executor to handle millions of schedules, see `docker/entrypoint.sh` / `schedule/workflow_schedule_task.py` for help.
+
+To Achieve this, a `WorkflowSchedulePlan` model was introduced in `models/trigger.py`, and a `events/event_handlers/sync_workflow_schedule_when_app_published.py` was used to sync workflow schedule plans when app is published.
+
+### Trigger Plugin
+
+`Trigger Plugin` node allows user define there own distributed trigger plugin, whenever a request was received, Dify forwards it to the plugin and wait for parsed variables from it.
+
+1. Requests were saved in storage by `services/trigger/trigger_request_service.py`, referenced by `services/trigger/trigger_service.py`.`TriggerService`.`process_endpoint`
+1. Plugins accept those requests and parse variables from it, see `core/plugin/impl/trigger.py` for details.
+
+A `subscription` concept was out here by Dify, it means an endpoint address from Dify was bound to thirdparty webhook service like `Github` `Slack` `Linear` `GoogleDrive` `Gmail` etc. Once a subscription was created, Dify continually receives requests from the platforms and handle them one by one.
+
+## Worker Pool / Async Task
+
+All the events that triggered a new workflow run is always in async mode, a unified entrypoint can be found here `services/async_workflow_service.py`.`AsyncWorkflowService`.`trigger_workflow_async`.
+
+The infrastructure we used is `celery`, we've already configured it in `docker/entrypoint.sh`, and the consumers are in `tasks/async_workflow_tasks.py`, 3 queues were used to handle different tiers of users, `PROFESSIONAL_QUEUE` `TEAM_QUEUE` `SANDBOX_QUEUE`.
+
+## Debug Strategy
+
+Dify divided users into 2 groups: builders / end users.
+
+Builders are the users who create workflows, in this stage, debugging a workflow becomes a critical part of the workflow development process, as the start node in workflows, trigger nodes can `listen` to the events from `WebhookDebug` `Schedule` `Plugin`, debugging process was created in `controllers/console/app/workflow.py`.`DraftWorkflowTriggerNodeApi`.
+
+A polling process can be considered as combine of few single `poll` operations, each `poll` operation fetches events cached in `Redis`, returns `None` if no event was found, more detailed implemented: `core/trigger/debug/event_bus.py` was used to handle the polling process, and `core/trigger/debug/event_selectors.py` was used to select the event poller based on the trigger type.
