+# JavaScript to TypeScript Migration Agent Guide
+
+**Complete technical reference for converting JavaScript/JSX files to TypeScript/TSX in Apache Superset frontend.**
+
+**Agent Role:** Atomic migration unit - migrate the core file + ALL related tests/mocks as one cohesive unit. Use `git mv` to preserve history, NO `git commit`. NO global import changes. Report results upon completion.
+
+---
+
+## 🎯 Migration Principles
+
+1. **Atomic migration units** - Core file + all related tests/mocks migrate together
+2. **Zero `any` types** - Use proper TypeScript throughout
+3. **Leverage existing types** - Reuse established definitions
+4. **Type inheritance** - Derivatives extend base component types
+5. **Strategic placement** - File types for maximum discoverability
+6. **Surgical improvements** - Enhance existing types during migration
+
+---
+
+## Step 0: Dependency Check (MANDATORY)
+
+**Command:**
+```bash
+grep -E "from '\.\./.*\.jsx?'|from '\./.*\.jsx?'|from 'src/.*\.jsx?'" superset-frontend/{filename}
+```
+
+**Decision:**
+- ✅ No matches → Proceed with atomic migration (core + tests + mocks)
+- ❌ Matches found → EXIT with dependency report (see format below)
+
+---
+
+## Step 1: Identify Related Files (REQUIRED)
+
+**Atomic Migration Scope:**
+For core file `src/utils/example.js`, also migrate:
+- `src/utils/example.test.js` / `src/utils/example.test.jsx`
+- `src/utils/example.spec.js` / `src/utils/example.spec.jsx`
+- `src/utils/__mocks__/example.js`
+- Any other related test/mock files found by pattern matching
+
+**Find all related test and mock files:**
+```bash
+# Pattern-based search for related files
+basename=$(basename {filename} .js)
+dirname=$(dirname superset-frontend/{filename})
+
+# Find test files
+find "$dirname" -name "${basename}.test.js" -o -name "${basename}.test.jsx"
+find "$dirname" -name "${basename}.spec.js" -o -name "${basename}.spec.jsx"
+
+# Find mock files  
+find "$dirname" -name "__mocks__/${basename}.js"
+find "$dirname" -name "${basename}.mock.js"
+```
+
+**Migration Requirement:** All discovered related files MUST be migrated together as one atomic unit.
+
+**Test File Creation:** If NO test files exist for the core file, CREATE a minimal test file using the following pattern:
+- Location: Same directory as core file
+- Name: `{basename}.test.ts` (e.g., `DebouncedMessageQueue.test.ts`)
+- Content: Basic test structure importing and testing the main functionality
+- Use proper TypeScript types in test file

+```
+
+### From Local Types (`src/types/`)
+```typescript

+ExplorePageInitialData, ExplorePageState, ExploreResponsePayload, OptionSortType
+
+// src/SqlLab/types.ts
+[SQL Lab specific types]
+```
+
+---
+
+## 🏗️ Type Organization Strategy
+
+### Type Placement Hierarchy
+
+1. **Component-Colocated** (90% of cases)
+   ```typescript
+   // Same file as component
+   interface MyComponentProps {
+     title: string;
+     onClick: () => void;
+   }
+   ```
+
+2. **Feature-Shared**
+   ```typescript
+   // src/[domain]/components/[Feature]/types.ts
+   export interface FilterConfiguration {
+     filterId: string;
+     targets: NativeFilterTarget[];
+   }
+   ```
+
+3. **Domain-Wide**
+   ```typescript
+   // src/[domain]/types.ts
+   export interface ExploreFormData extends QueryFormData {
+     viz_type: string;
+   }
+   ```
+
+4. **Global**
+   ```typescript
+   // src/types/[TypeName].ts
+   export interface ApiResponse<T> {
+     result: T;
+     count?: number;
+   }
+   ```
+
+### Type Discovery Commands
+```bash
+# Search existing types before creating
+find superset-frontend/src -name "types.ts" -exec grep -l "[TypeConcept]" {} \;
+grep -r "interface.*Props\|type.*Props" superset-frontend/src/
+```
+
+### Derivative Component Patterns
+
+**Rule:** Components that extend others should extend their type interfaces.
+
+```typescript
+// ✅ Base component type
+interface SelectProps {
+  value: string | number;
+  options: SelectOption[];
+  onChange: (value: string | number) => void;
+  disabled?: boolean;
+}
+
+// ✅ Derivative extends base
+interface ChartSelectProps extends SelectProps {
+  charts: Chart[];
+  onChartSelect: (chart: Chart) => void;
+}
+
+// ✅ Derivative with modified props  
+interface DatabaseSelectProps extends Omit<SelectProps, 'value' | 'onChange'> {
+  value: number;  // Narrowed type
+  onChange: (databaseId: number) => void;  // Specific signature
+}
+```
+
+**Common Patterns:**
+- **Extension:** `extends BaseProps` - adds new props
+- **Omission:** `Omit<BaseProps, 'prop'>` - removes props
+- **Modification:** `Omit<BaseProps, 'prop'> & { prop: NewType }` - changes prop type
+- **Restriction:** Override with narrower types (union → specific)
+

+
+## 📋 Migration Recipe
+
+### Step 2: File Conversion
+```bash
+# Use git mv to preserve history
+git mv component.js component.ts
+git mv Component.jsx Component.tsx
+```
+
+### Step 3: Import & Type Setup
+```typescript
+// Import order (enforced by linting)
+import { FC, ReactNode } from 'react';
+import { JsonObject, QueryFormData } from '@superset-ui/core';
+import { Dataset } from '@superset-ui/chart-controls';
+import type { Dashboard } from 'src/types/Dashboard';
+```
+
+### Step 4: Function & Component Typing
+```typescript
+// Functions with proper parameter/return types
+export function processData(
+  data: Dataset[],
+  config: JsonObject
+): ProcessedData[] {
+  // implementation
+}
+
+// Component props with inheritance
+interface ComponentProps extends BaseProps {
+  data: Chart[];
+  onSelect: (id: number) => void;
+}
+
+const Component: FC<ComponentProps> = ({ data, onSelect }) => {
+  // implementation
+};
+```
+
+### Step 5: State & Redux Typing
+```typescript
+// Hooks with specific types
+const [data, setData] = useState<Chart[]>([]);
+const [selected, setSelected] = useState<number | null>(null);
+
+// Redux with existing RootState
+const mapStateToProps = (state: RootState) => ({
+  charts: state.charts,
+  user: state.user,
+});
+```
+

+
+## 🧠 Type Debugging Strategies (Real-World Learnings)
+
+### The Evolution of Type Approaches
+When you hit type errors, follow this debugging evolution:
+
+#### 1. ❌ Idealized Union Types (First Attempt)
+```typescript
+// Looks clean but doesn't match reality
+type DatasourceInput = Datasource | QueryEditor;
+```
+**Problem**: Real calling sites pass variations, not exact types.
+
+#### 2. ❌ Overly Precise Types (Second Attempt)
+```typescript
+// Tried to match exact calling signatures
+type DatasourceInput =
+  | IDatasource  // From DatasourcePanel
+  | (QueryEditor & { columns: ColumnMeta[] });  // From SaveQuery
+```
+**Problem**: Too rigid, doesn't handle legacy variations.
+
+#### 3. ✅ Flexible Interface (Final Solution)
+```typescript
+// Captures what the function actually needs
+interface DatasourceInput {
+  name?: string | null;  // Allow null for compatibility
+  datasource_name?: string | null;  // Legacy variations
+  columns?: any[];  // Multiple column types accepted
+  database?: { id?: number };
+  // ... other optional properties
+}
+```
+**Success**: Works with all calling sites, focuses on function needs.
+
+### Type Debugging Process
+1. **Start with compilation errors** - they show exact mismatches
+2. **Examine actual usage** - look at calling sites, not idealized types  
+3. **Build flexible interfaces** - capture what functions need, not rigid contracts
+4. **Iterate based on downstream validation** - let calling sites guide your types
+
+---
+
+## 🚨 Anti-Patterns to Avoid
+
+```typescript
+// ❌ Never use any
+const obj: any = {};
+
+// ✅ Use proper types
+const obj: Record<string, JsonObject> = {};
+
+// ❌ Don't recreate base component props
+interface ChartSelectProps {
+  value: string;     // Duplicated from SelectProps
+  onChange: () => void;  // Duplicated from SelectProps
+  charts: Chart[];   // New prop
+}
+
+// ✅ Inherit and extend
+interface ChartSelectProps extends SelectProps {
+  charts: Chart[];   // Only new props
+}
+
+// ❌ Don't create ad-hoc type variations
+interface UserInfo {
+  name: string;
+  email: string;
+}
+
+// ✅ Extend existing types (DRY principle)
+import { User } from 'src/types/bootstrapTypes';
+type UserDisplayInfo = Pick<User, 'firstName' | 'lastName' | 'email'>;
+
+// ❌ Don't create overly rigid unions
+type StrictInput = ExactTypeA | ExactTypeB;
+
+// ✅ Create flexible interfaces for function parameters
+interface FlexibleInput {
+  // Focus on what the function actually needs
+  commonProperty: string;
+  optionalVariations?: any;  // Allow for legacy variations
+}
+```
+
+## 📍 DRY Type Guidelines (WHERE TYPES BELONG)
+
+### Type Placement Rules
+**CRITICAL**: Type variations must live close to where they belong, not scattered across files.
+
+#### ✅ Proper Type Organization
+```typescript
+// ❌ Don't create one-off interfaces in utility files
+// src/utils/datasourceUtils.ts
+interface DatasourceInput { /* custom interface */ }  // Wrong!
+
+// ✅ Use existing types or extend them in their proper domain
+// src/utils/datasourceUtils.ts
+import { IDatasource } from 'src/explore/components/DatasourcePanel';
+import { QueryEditor } from 'src/SqlLab/types';
+
+// Create flexible interface that references existing types
+interface FlexibleDatasourceInput {
+  // Properties that actually exist across variations
+}
+```
+
+#### Type Location Hierarchy
+1. **Domain Types**: `src/{domain}/types.ts` (dashboard, explore, SqlLab)
+2. **Component Types**: Co-located with components  
+3. **Global Types**: `src/types/` directory
+4. **Utility Types**: Only when they truly don't belong elsewhere
+
+#### ✅ DRY Type Patterns
+```typescript
+// ✅ Extend existing domain types
+interface SaveQueryData extends Pick<QueryEditor, 'sql' | 'dbId' | 'catalog'> {
+  columns: ColumnMeta[];  // Add what's needed
+}
+
+// ✅ Create flexible interfaces for cross-domain utilities
+interface CrossDomainInput {
+  // Common properties that exist across different source types
+  name?: string | null;  // Accommodate legacy null values
+  // Only include properties the function actually uses
+}
+```
+
+---
+
+## 🎯 PropTypes Auto-Generation (Elegant Approach)
+
+**IMPORTANT**: Superset has `babel-plugin-typescript-to-proptypes` configured to automatically generate PropTypes from TypeScript interfaces. Use this instead of manual PropTypes duplication!
+
+### ❌ Manual PropTypes Duplication (Avoid This)
+```typescript
+export interface MyComponentProps {
+  title: string;
+  count?: number;
+}
+
+// 8+ lines of manual PropTypes duplication 😱
+const propTypes = PropTypes.shape({
+  title: PropTypes.string.isRequired,
+  count: PropTypes.number,
+});
+
+export default propTypes;
+```
+
+### ✅ Auto-Generated PropTypes (Use This)
+```typescript
+import { InferProps } from 'prop-types';
+
+export interface MyComponentProps {
+  title: string;
+  count?: number;
+}
+
+// Single validator function - babel plugin auto-generates PropTypes! ✨
+export default function MyComponentValidator(props: MyComponentProps) {
+  return null; // PropTypes auto-assigned by babel-plugin-typescript-to-proptypes
+}
+
+// Optional: For consumers needing PropTypes type inference
+export type MyComponentPropsInferred = InferProps<typeof MyComponentValidator>;
+```
+
+### Migration Pattern for Type-Only Files
+
+**When migrating type-only files with manual PropTypes:**
+
+1. **Keep the TypeScript interfaces** (single source of truth)
+2. **Replace manual PropTypes** with validator function
+3. **Remove PropTypes imports** and manual shape definitions
+4. **Add InferProps import** if type inference needed
+
+**Example Migration:**
+```typescript
+// Before: 25+ lines with manual PropTypes duplication
+export interface AdhocFilterType { /* ... */ }
+const adhocFilterTypePropTypes = PropTypes.oneOfType([...]);
+
+// After: 3 lines with auto-generation
+export interface AdhocFilterType { /* ... */ }
+export default function AdhocFilterValidator(props: { filter: AdhocFilterType }) {
+  return null; // Auto-generated PropTypes by babel plugin
+}
+```
+
+### Component PropTypes Pattern
+
+**For React components, the babel plugin works automatically:**
+
+```typescript
+interface ComponentProps {
+  title: string;
+  onClick: () => void;
+}
+
+const MyComponent: FC<ComponentProps> = ({ title, onClick }) => {
+  // Component implementation
+};
+
+// PropTypes automatically generated by babel plugin - no manual work needed!
+export default MyComponent;
+```
+
+### Auto-Generation Benefits
+
+- ✅ **Single source of truth**: TypeScript interfaces drive PropTypes
+- ✅ **No duplication**: Eliminate 15-20 lines of manual PropTypes code
+- ✅ **Automatic updates**: Changes to TypeScript automatically update PropTypes
+- ✅ **Type safety**: Compile-time checking ensures PropTypes match interfaces
+- ✅ **Backward compatibility**: Existing JavaScript components continue working
+
+### Babel Plugin Configuration
+
+The plugin is already configured in `babel.config.js`:
+```javascript
+['babel-plugin-typescript-to-proptypes', { loose: true }]
+```
+
+**No additional setup required** - just use TypeScript interfaces and the plugin handles the rest!
+
+---
+
+## 🧪 Test File Migration Patterns
+
+### Test File Priority
+- **Always migrate test files** alongside production files
+- **Test files are often leaf nodes** - good starting candidates
+- **Create tests if missing** - Leverage new TypeScript types for better test coverage
+
+### Test-Specific Type Patterns
+```typescript
+// Mock interfaces for testing
+interface MockStore {
+  getState: () => Partial<RootState>;  // Partial allows minimal mocking
+}
+
+// Type-safe mocking for complex objects
+const mockDashboardInfo: Partial<DashboardInfo> as DashboardInfo = {
+  id: 123,
+  json_metadata: '{}',
+};
+
+// Sinon stub typing
+let postStub: sinon.SinonStub;
+beforeEach(() => {
+  postStub = sinon.stub(SupersetClient, 'post');
+});
+
+// Use stub reference instead of original method
+expect(postStub.callCount).toBe(1);
+expect(postStub.getCall(0).args[0].endpoint).toMatch('/api/');
+```
+
+### Test Migration Recipe
+1. **Migrate production file first** (if both need migration)
+2. **Update test imports** to point to `.ts/.tsx` files
+3. **Add proper mock typing** using `Partial<T> as T` pattern
+4. **Fix stub typing** - Use stub references, not original methods
+5. **Verify all tests pass** with TypeScript compilation
+
+---
+
+## 🔧 Type Conflict Resolution
+
+### Multiple Type Definitions Issue
+**Problem**: Same type name defined in multiple files causes compilation errors.
+
+**Example**: `DashboardInfo` defined in both:
+- `src/dashboard/reducers/types.ts` (minimal)
+- `src/dashboard/components/Header/types.ts` (different shape)  
+- `src/dashboard/types.ts` (complete - used by RootState)
+
+### Resolution Strategy
+1. **Identify the authoritative type**:
+   ```bash
+   # Find which type is used by RootState/main interfaces
+   grep -r "DashboardInfo" src/dashboard/types.ts
+   ```
+
+2. **Use import from authoritative source**:
+   ```typescript
+   // ✅ Import from main domain types
+   import { RootState, DashboardInfo } from 'src/dashboard/types';
+
+   // ❌ Don't import from component-specific files
+   import { DashboardInfo } from 'src/dashboard/components/Header/types';
+   ```
+
+3. **Mock complex types in tests**:
+   ```typescript
+   // For testing - provide minimal required fields
+   const mockInfo: Partial<DashboardInfo> as DashboardInfo = {
+     id: 123,
+     json_metadata: '{}',
+     // Only provide fields actually used in test
+   };
+   ```
+
+### Type Hierarchy Discovery Commands
+```bash
+# Find all definitions of a type
+grep -r "interface.*TypeName\|type.*TypeName" src/
+
+# Find import usage patterns
+grep -r "import.*TypeName" src/
+
+# Check what RootState uses
+grep -A 10 -B 10 "TypeName" src/*/types.ts
+```
+
+---
+
+## Agent Constraints (CRITICAL)
+
+1. **Use git mv** - Run `git mv file.js file.ts` to preserve git history, but NO `git commit`
+2. **NO global import changes** - Don't update imports across codebase
+3. **Type files OK** - Can modify existing type files to improve/align types
+4. **Single-File TypeScript Validation** (CRITICAL) - tsc has known issues with multi-file compilation:
+   - **Core Issue**: TypeScript's `tsc` has documented problems validating multiple files simultaneously in complex projects
+   - **Solution**: ALWAYS validate files one at a time using individual `tsc` calls
+   - **Command Pattern**: `cd superset-frontend && npx tscw --noEmit --allowJs --composite false --project tsconfig.json {single-file-path}`
+   - **Why**: Multi-file validation can produce false positives, miss real errors, and conflict during parallel agent execution
+5. **Downstream Impact Validation** (CRITICAL) - Your migration affects calling sites:
+   - **Find downstream files**: `find superset-frontend/src -name "*.tsx" -o -name "*.ts" | xargs grep -l "your-core-filename" 2>/dev/null || echo "No files found"`
+   - **Validate each downstream file individually**: `cd superset-frontend && npx tscw --noEmit --allowJs --composite false --project tsconfig.json {each-downstream-file}`
+   - **Fix type mismatches** you introduced in calling sites
+   - **NEVER ignore downstream errors** - they indicate your types don't match reality
+6. **Avoid Project-Wide Validation During Migration**:
+   - **NEVER use `npm run type`** during parallel agent execution - produces unreliable results
+   - **Single-file validation is authoritative** - trust individual file checks over project-wide scans
+6. **ESLint validation** - Run `npm run eslint -- --fix {file}` for each migrated file to auto-fix formatting/linting issues
+6. Zero `any` types - use proper TypeScript types
+7. Search existing types before creating new ones
+8. Follow patterns from this guide
+

+# JS-to-TS Coordinator Workflow
+
+**Role:** Strategic migration coordination - select leaf-node files, trigger agents, review results, handle integration, manage dependencies.
+
+---
+
+## 1. Core File Selection Strategy
+
+**Target ONLY Core Files**: Coordinators identify core files (production code), agents handle related tests/mocks atomically.
+
+**File Analysis Commands**:
+```bash
+# Find CORE files with no JS/JSX dependencies (exclude tests/mocks) - SIZE PRIORITIZED
+find superset-frontend/src -name "*.js" -o -name "*.jsx" | grep -v "test\|spec\|mock" | xargs wc -l | sort -n | head -20
+
+# Alternative: Get file sizes in lines with paths
+find superset-frontend/src -name "*.js" -o -name "*.jsx" | grep -v "test\|spec\|mock" | while read file; do
+  lines=$(wc -l < "$file")
+  echo "$lines $file"
+done | sort -n | head -20
+
+# Check dependencies for core files only (start with smallest)
+for file in <core-files-sorted-by-size>; do
+  echo "=== $file ($(wc -l < "$file") lines) ==="
+  grep -E "from '\.\./.*\.jsx?'|from '\./.*\.jsx?'|from 'src/.*\.jsx?'" "$file" || echo "✅ LEAF CANDIDATE"
+done
+
+# Identify heavily imported files (migrate last)  
+grep -r "from.*utils/common" superset-frontend/src/ | wc -l
+
+# Quick leaf analysis with size priority
+find superset-frontend/src -name "*.js" -o -name "*.jsx" | grep -v "test\|spec\|mock" | head -30 | while read file; do
+  deps=$(grep -E "from '\.\./.*\.jsx?'|from '\./.*\.jsx?'|from 'src/.*\.jsx?'" "$file" | wc -l)
+  lines=$(wc -l < "$file")
+  if [ "$deps" -eq 0 ]; then
+    echo "✅ LEAF: $lines lines - $file"
+  fi
+done | sort -n
+```
+
+**Priority Order** (Smallest files first for easier wins):
+1. **Small leaf files** (<50 lines) - No JS/JSX imports, quick TypeScript conversion
+2. **Medium leaf files** (50-200 lines) - Self-contained utilities and helpers  
+3. **Small dependency files** (<100 lines) - Import only already-migrated files
+4. **Larger components** (200+ lines) - Complex but well-contained functionality
+5. **Core foundational files** (utils/common.js, controls.jsx) - migrate last regardless of size
+
+**Size-First Benefits**:
+- Faster completion builds momentum
+- Earlier validation of migration patterns
+- Easier rollback if issues arise
+- Better success rate for agent learning
+
+**Migration Unit**: Each agent call migrates:
+- 1 core file (primary target)
+- All related `*.test.js/jsx` files
+- All related `*.mock.js` files  
+- All related `__mocks__/` files
+
+---
+
+## 2. Task Creation & Agent Control
+
+### Task Triggering
+When triggering the `/js-to-ts` command:
+- **Task Title**: Use the core filename as the task title (e.g., "DebouncedMessageQueue.js migration", "hostNamesConfig.js migration")
+- **Task Description**: Include the full relative path to help agent locate the file
+- **Reference**: Point agent to [AGENT.md](./AGENT.md) for technical instructions
+
+### Post-Processing Workflow
+After each agent completes:
+
+1. **Review Agent Report**: Always read and analyze the complete agent report
+2. **Share Summary**: Provide user with key highlights from agent's work:
+   - Files migrated (core + tests/mocks)
+   - Types created or improved
+   - Any validation issues or coordinator actions needed
+3. **Quality Assessment**: Evaluate agent's TypeScript implementation against criteria:
+   - ✅ **Type Usage**: Proper types used, no `any` types
+   - ✅ **Type Filing**: Types placed in correct hierarchy (component → feature → domain → global)
+   - ✅ **Side Effects**: No unintended changes to other files
+   - ✅ **Import Alignment**: Proper .ts/.tsx import extensions
+4. **Integration Decision**:
+   - **COMMIT**: If agent work is complete and high quality
+   - **FIX & COMMIT**: If minor issues need coordinator fixes
+   - **ROLLBACK**: If major issues require complete rework
+5. **Next Action**: Ask user preference - commit this work or trigger next migration
+
+---
+
+## 3. Integration Decision Framework
+
+**Automatic Integration** ✅:
+- `npm run type` passes without errors
+- Agent created clean TypeScript with proper types
+- Types appropriately filed in hierarchy
+
+**Coordinator Integration** (Fix Side-Effects) 🔧:
+- `npm run type` fails BUT agent's work is high quality
+- Good type usage, proper patterns, well-organized
+- Side-effects are manageable TypeScript compilation errors
+- **Coordinator Action**: Integrate the change, then fix global compilation issues
+
+**Rollback Only** ❌:
+- Agent introduced `any` types or poor type choices
+- Types poorly organized or conflicting with existing patterns
+- Fundamental approach issues requiring complete rework
+
+**Integration Process**:
+1. **Review**: Agent already used `git mv` to preserve history
+2. **Fix Side-Effects**: Update dependent files with proper import extensions
+3. **Resolve Types**: Fix any cascading type issues across codebase
+4. **Validate**: Ensure `npm run type` passes after fixes
+
+---
+
+## 4. Common Integration Patterns
+
+**Common Side-Effects (Expect These)**:
+- **Type import conflicts**: Multiple definitions of same type name
+- **Mock object typing**: Tests need complete type satisfaction
+- **Stub method references**: Use stub vars instead of original methods
+
+**Coordinator Fixes (Standard Process)**:
+1. **Import Resolution**:
+   ```bash
+   # Find authoritative type source
+   grep -r "TypeName" src/*/types.ts
+   # Import from domain types (src/dashboard/types.ts) not component types
+   ```
+
+2. **Test Mock Completion**:
+   ```typescript
+   // Use Partial<T> as T pattern for minimal mocking
+   const mockDashboard: Partial<DashboardInfo> as DashboardInfo = {
+     id: 123,
+     json_metadata: '{}',
+   };
+   ```
+
+3. **Stub Reference Fixes**:
+   ```typescript
+   // ✅ Use stub variable
+   expect(postStub.callCount).toBe(1);
+   // ❌ Don't use original method
+   expect(SupersetClient.post.callCount).toBe(1);
+   ```
+
+4. **Validation Commands**:
+   ```bash
+   npm run type          # TypeScript compilation
+   npm test -- filename  # Test functionality
+   git status           # Should show rename, not add/delete
+   ```
+
+---
+
+## 5. File Categories for Planning
+
+### Leaf Files (Start Here)
+**Self-contained files with minimal JS/JSX dependencies**:
+- Test files (80 files) - Usually only import the file being tested
+- Utility files without internal dependencies
+- Components importing only external libraries
+
+### Heavily Imported Files (Migrate Last)
+**Core files that many others depend on**:
+- `utils/common.js` - Core utility functions
+- `utils/reducerUtils.js` - Redux helpers  
+- `@superset-ui/core` equivalent files
+- Major state management files (`explore/store.js`, `dashboard/actions/`)
+
+### Complex Components (Middle Priority)  
+**Large files requiring careful type analysis**:
+- `components/Datasource/DatasourceEditor.jsx` (1,809 lines)
+- `explore/components/controls/AnnotationLayerControl/AnnotationLayer.jsx` (1,031 lines)
+- `explore/components/ExploreViewContainer/index.jsx` (911 lines)
+
+---
+
+## 6. Success Metrics & Continuous Improvement
+
+**Per-File Gates**:
+- ✅ `npm run type` passes after each migration
+- ✅ Zero `any` types introduced
+- ✅ All imports properly typed
+- ✅ Types filed in correct hierarchy
+
+**Linear Scheduling**:
+When agents report `DEPENDENCY_BLOCK`:
+- Queue dependencies in linear order
+- Process one file at a time to avoid conflicts
+- Handle cascading type changes between files
+
+**After Each Migration**:
+1. **Update guides** with new patterns discovered
+2. **Document coordinator fixes** that become common
+3. **Enhance agent instructions** based on recurring issues
+4. **Track success metrics** - automatic vs coordinator integration rates

+# JavaScript to TypeScript Migration Project
+
+Progressive migration of 219 JS/JSX files to TypeScript in Apache Superset frontend.
+
+## 📁 Project Documentation
+
+- **[AGENT.md](./AGENT.md)** - Complete technical migration guide for agents (includes type reference, patterns, validation)
+- **[COORDINATOR.md](./COORDINATOR.md)** - Strategic workflow for coordinators (file selection, task management, integration)
+
+## 🎯 Quick Start
+
+**For Agents:** Read [AGENT.md](./AGENT.md) for complete migration instructions
+**For Coordinators:** Read [COORDINATOR.md](./COORDINATOR.md) for workflow and [AGENT.md](./AGENT.md) for supervision
+
+**Command:** `/js-to-ts <filename>` - See [../../commands/js-to-ts.md](../../commands/js-to-ts.md)
+
+## 📊 Migration Progress
+
+**Scope**: 219 files total (112 JS + 107 JSX)
+- Production files: 139 (63%)  
+- Test files: 80 (37%)
+
+**Strategy**: Leaf-first migration with dependency-aware coordination
+
+### Completed Migrations ✅
+
+1. **roundDecimal** - `plugins/legacy-plugin-chart-map-box/src/utils/roundDecimal.js`
+   - Migrated core + test files
+   - Added proper TypeScript function signature with optional precision parameter
+   - All tests pass
+
+2. **timeGrainSqlaAnimationOverrides** - `src/explore/controlPanels/timeGrainSqlaAnimationOverrides.js`
+   - Migrated to TypeScript with ControlPanelState and Dataset types
+   - Added TimeGrainOverrideState interface for return type
+   - Used type guards for safe property access
+
+3. **DebouncedMessageQueue** - `src/utils/DebouncedMessageQueue.js`
+   - Migrated to TypeScript with proper generics
+   - Created DebouncedMessageQueueOptions interface
+   - **CREATED test file** with 4 comprehensive test cases
+   - Excellent class property typing with private/readonly modifiers
+
+**Files Migrated**: 3/219 (1.4%)
+**Tests Created**: 2 (roundDecimal had existing, DebouncedMessageQueue created)
+
+### Next Candidates (Leaf Nodes) 🎯
+
+**Identified leaf files with no JS/JSX dependencies:**
+- `src/utils/hostNamesConfig.js` - Domain configuration utility
+- `src/explore/controlPanels/Separator.js` - Control panel configuration  
+- `src/middleware/loggerMiddleware.js` - Logging middleware
+
+**Migration Quality**: All completed migrations have:
+- ✅ Zero `any` types
+- ✅ Proper TypeScript compilation
+- ✅ ESLint validation passed
+- ✅ Test coverage (created where missing)
+
+---
+
+## 📈 Success Metrics
+
+**Per-File Gates**:
+- ✅ `npm run type` passes after each migration
+- ✅ Zero `any` types introduced  
+- ✅ All imports properly typed
+- ✅ Types filed in correct hierarchy
+
+**Overall Progress**:
+- **Automatic Integration Rate**: 100% (3/3 migrations required no coordinator fixes)
+- **Test Coverage**: Improved (1 new test file created)
+- **Type Safety**: Enhanced with proper interfaces and generics

+### Test Structure Guidelines
+- **Use `test()` instead of `describe()` and `it()`** - Follow the [avoid nesting when testing](https://kentcdodds.com/blog/avoid-nesting-when-youre-testing) principle
+  - **Why**: Reduces unnecessary nesting, improves test isolation, and makes tests more readable
+  - **Pattern**: Write flat test files with descriptive test names that fully describe what's being tested
+  - **Example**: Instead of nested `describe('Component', () => { it('should render', ...) })`, use `test('Component renders correctly', ...)`
+  - **Benefits**:
+    - Each test stands alone with a clear, searchable name
+    - Easier to run individual tests
+    - Forces you to write more descriptive test names
+    - Reduces cognitive overhead from nested context switching
+

 ### E2E Integration Testing
 
-For E2E testing, we recommend that you use a `docker compose` backend
+**Note: We are migrating from Cypress to Playwright. Use Playwright for new tests.**
+
+#### Playwright (Recommended - NEW)
+
+For E2E testing with Playwright, use the same `docker compose` backend:
 
 ```bash
 CYPRESS_CONFIG=true docker compose up --build
 ```
-`docker compose` will get to work and expose a Cypress-ready Superset app.
-This app uses a different database schema (`superset_cypress`) to keep it isolated from
-your other dev environment(s), a specific set of examples, and a set of configurations that
-aligns with the expectations within the end-to-end tests.  Also note that it's served on a
-different port than the default port for the backend (`8088`).
 
-Now in another terminal, let's get ready to execute some Cypress commands. First, tell cypress
-to connect to the Cypress-ready Superset backend.
+The backend setup is identical - this exposes a test-ready Superset app on port 8081 with isolated database schema (`superset_cypress`), test data, and configurations.
 
+Now in another terminal, run Playwright tests:
+
+```bash
+# Navigate to frontend directory (Playwright config is here)
+cd superset-frontend
+
+# Run all Playwright tests
+npm run playwright:test
+# or: npx playwright test
+
+# Run with interactive UI for debugging
+npm run playwright:ui
+# or: npx playwright test --ui
+
+# Run in headed mode (see browser)
+npm run playwright:headed
+# or: npx playwright test --headed
+
+# Run specific test file
+npx playwright test tests/auth/login.spec.ts
+
+# Run with debug mode (step through tests)
+npm run playwright:debug tests/auth/login.spec.ts
+# or: npx playwright test --debug tests/auth/login.spec.ts
+
+# Generate test report
+npx playwright show-report
 ```
+
+Configuration is in `superset-frontend/playwright.config.ts`. Base URL is automatically set to `http://localhost:8088` but will use `PLAYWRIGHT_BASE_URL` if provided.
+
+#### Cypress (DEPRECATED - will be removed in Phase 5)
+
+:::warning
+Cypress is being phased out in favor of Playwright. Use Playwright for all new tests.
+:::
+
+```bash
+# Set base URL for Cypress

+# Playwright E2E Tests for Superset
+
+This directory contains Playwright end-to-end tests for Apache Superset, designed as a replacement for the existing Cypress tests during the migration to Playwright.
+
+## Architecture
+
+```
+playwright/
+├── components/core/     # Reusable UI components
+├── pages/              # Page Object Models  
+├── tests/              # Test files organized by feature
+├── utils/              # Shared constants and utilities
+└── README.md           # This file
+```
+
+## Design Principles
+
+We follow **YAGNI** (You Aren't Gonna Need It), **DRY** (Don't Repeat Yourself), and **KISS** (Keep It Simple, Stupid) principles:
+
+- Build only what's needed now
+- Reuse existing patterns and components
+- Keep solutions simple and maintainable
+
+## Component Architecture
+
+### Core Components (`components/core/`)
+
+Reusable UI interaction classes for common elements:
+
+- **Form**: Container with properly scoped child element access
+- **Input**: Supports `fill()`, `type()`, and `pressSequentially()` methods
+- **Button**: Standard click, hover, focus interactions
+
+**Usage Example:**
+```typescript
+import { Form } from '../components/core';
+
+const loginForm = new Form(page, '[data-test="login-form"]');
+const usernameInput = loginForm.getInput('[data-test="username-input"]');
+await usernameInput.fill('admin');
+```
+
+### Page Objects (`pages/`)
+
+Each page object encapsulates:
+- **Actions**: What you can do on the page
+- **Queries**: Information you can get from the page  
+- **Selectors**: Centralized in private static SELECTORS constant
+- **NO Assertions**: Keep assertions in test files
+
+**Page Object Pattern:**
+```typescript
+export class AuthPage {
+  // Selectors centralized in the page object
+  private static readonly SELECTORS = {
+    LOGIN_FORM: '[data-test="login-form"]',
+    USERNAME_INPUT: '[data-test="username-input"]',
+  } as const;
+
+  // Actions - what you can do
+  async loginWithCredentials(username: string, password: string) { }
+
+  // Queries - information you can get  
+  async getCurrentUrl(): Promise<string> { }
+
+  // NO assertions - those belong in tests
+}
+```
+
+### Tests (`tests/`)
+
+Organized by feature/area (auth, dashboard, charts, etc.):
+- Use page objects for actions
+- Keep assertions in test files  
+- Import shared constants from `utils/`
+
+**Test Pattern:**
+```typescript
+import { test, expect } from '@playwright/test';
+import { AuthPage } from '../../pages/AuthPage';
+import { LOGIN } from '../../utils/urls';
+
+test('should login with correct credentials', async ({ page }) => {
+  const authPage = new AuthPage(page);
+  await authPage.goto();
+  await authPage.loginWithCredentials('admin', 'general');
+
+  // Assertions belong in tests, not page objects
+  expect(await authPage.getCurrentUrl()).not.toContain(LOGIN);
+});
+```
+
+### Utilities (`utils/`)
+
+Shared constants and utilities:
+- **urls.ts**: URL paths and request patterns
+- Keep flat exports (no premature namespacing)
+
+## Contributing Guidelines
+
+### Adding New Tests
+
+1. **Check existing components** before creating new ones
+2. **Use page objects** for page interactions  
+3. **Keep assertions in tests**, not page objects
+4. **Follow naming conventions**: `feature.spec.ts`
+
+### Adding New Components
+
+1. **Follow YAGNI**: Only build what's immediately needed
+2. **Use Locator-based scoping** for proper element isolation
+3. **Support both string selectors and Locator objects** via constructor overloads
+4. **Add to `components/core/index.ts`** for easy importing
+
+### Adding New Page Objects
+
+1. **Centralize selectors** in private static SELECTORS constant
+2. **Import shared constants** from `utils/urls.ts`
+3. **Actions and queries only** - no assertions
+4. **Use existing components** for DOM interactions
+
+## Running Tests
+
+```bash
+# Run all tests
+npm run playwright:test
+# or: npx playwright test
+
+# Run specific test file
+npx playwright test tests/auth/login.spec.ts
+
+# Run with UI mode for debugging
+npm run playwright:ui
+# or: npx playwright test --ui
+
+# Run in headed mode (see browser)
+npm run playwright:headed
+# or: npx playwright test --headed
+
+# Debug specific test file
+npm run playwright:debug tests/auth/login.spec.ts
+# or: npx playwright test --debug tests/auth/login.spec.ts
+```
+
+## Test Reports
+
+Playwright generates multiple reports for better visibility:
+
+```bash
+# View interactive HTML report (opens automatically on failure)
+npm run playwright:report
+# or: npx playwright show-report
+
+# View test trace for debugging failures
+npx playwright show-trace test-results/[test-name]/trace.zip
+```
+
+### Report Types
+
+- **List Reporter**: Shows progress and summary table in terminal
+- **HTML Report**: Interactive web interface with screenshots, videos, and traces
+- **JSON Report**: Machine-readable format in `test-results/results.json`
+- **GitHub Actions**: Annotations in CI for failed tests
+
+### Debugging Failed Tests
+
+When tests fail, Playwright automatically captures:
+- **Screenshots** at the point of failure
+- **Videos** of the entire test run
+- **Traces** with timeline and network activity
+- **Error context** with detailed debugging information
+
+All debugging artifacts are available in the HTML report for easy analysis.
+
+## Configuration
+
+- **Config**: `playwright.config.ts` - matches Cypress settings
+- **Base URL**: `http://localhost:8088` (assumes Superset running)
+- **Browsers**: Chrome only for Phase 1 (YAGNI)
+- **Retries**: 2 in CI, 0 locally (matches Cypress)
+
+## Migration from Cypress
+
+When porting Cypress tests:
+
+1. **Port the logic**, not the implementation
+2. **Use page objects** instead of inline selectors
+3. **Replace `cy.intercept/cy.wait`** with `page.waitForRequest()`
+4. **Use shared constants** from `utils/urls.ts`
+5. **Follow the established patterns** shown in `tests/auth/login.spec.ts`
+
+## Best Practices
+
+- **Centralize selectors** in page objects
+- **Centralize URLs** in `utils/urls.ts`  
+- **Use meaningful test descriptions**
+- **Keep page objects action-focused**
+- **Put assertions in tests, not page objects**
+- **Follow the existing patterns** for consistency
