+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'
+import { ModelModeType } from '@/types/app'
+
+interface UseModelConfigParams {
+  initialConfig?: Partial<ModelConfig>
+  currModel?: { model_properties?: { mode?: ModelModeType } }
+  hasFetchedDetail: boolean
+}
+
+interface UseModelConfigReturn {
+  modelConfig: ModelConfig
+  setModelConfig: (config: ModelConfig) => void
+  completionParams: FormValue
+  setCompletionParams: (params: FormValue) => void
+  modelModeType: ModelModeType
+}
+
+export const useModelConfig = ({
+  initialConfig,
+  currModel,
+  hasFetchedDetail,
+}: UseModelConfigParams): UseModelConfigReturn => {
+  const [modelConfig, setModelConfig] = useState<ModelConfig>({
+    provider: 'langgenius/openai/openai',
+    model_id: 'gpt-3.5-turbo',
+    mode: ModelModeType.unset,
+    // ... default values
+    ...initialConfig,
+  })
+  
+  const [completionParams, setCompletionParams] = useState<FormValue>({})
+  
+  const modelModeType = modelConfig.mode
+
+  // Fill old app data missing model mode
+  useEffect(() => {
+    if (hasFetchedDetail && !modelModeType) {
+      const mode = currModel?.model_properties?.mode
+      if (mode) {
+        setModelConfig(produce(modelConfig, (draft) => {
+          draft.mode = mode
+        }))
+      }
+    }
+  }, [hasFetchedDetail, modelModeType, currModel])
+
+  return {
+    modelConfig,
+    setModelConfig,
+    completionParams,
+    setCompletionParams,
+    modelModeType,
+  }
+}
+```
+
+### 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')
+  })
+})
+```

+Unit tests for DatasetRetrieval.process_metadata_filter_func.
+
+This module provides comprehensive test coverage for the process_metadata_filter_func
+method in the DatasetRetrieval class, which is responsible for building SQLAlchemy
+filter expressions based on metadata filtering conditions.
+
+Conditions Tested:
+==================
+1. **String Conditions**: contains, not contains, start with, end with
+2. **Equality Conditions**: is / =, is not / ≠
+3. **Null Conditions**: empty, not empty
+4. **Numeric Comparisons**: before / <, after / >, ≤ / <=, ≥ / >=
+5. **List Conditions**: in
+6. **Edge Cases**: None values, different data types (str, int, float)
+
+Test Architecture:
+==================
+- Direct instantiation of DatasetRetrieval
+- Mocking of DatasetDocument model attributes
+- Verification of SQLAlchemy filter expressions
+- Follows Arrange-Act-Assert (AAA) pattern
+
+Running Tests:
