+
+Remove `Provider` from `@shopify/app-bridge-react` imports and unwrap JSX elements.
+
+## What it does
+
+- Removes `Provider` from named imports of `@shopify/app-bridge-react`
+- Handles aliased imports like `Provider as AppProvider`
+- Unwraps `<Provider>...</Provider>` JSX elements, leaving only the children
+- Unwraps aliased Provider JSX elements like `<AppProvider>...</AppProvider>`
+- Removes self-closing `<Provider />` elements
+- Handles `React.createElement(Provider, ...)` calls
+- Removes entire import statement when only `Provider` is imported
+
+## Usage
+
+```bash
+npx codemod@latest workflow run -w workflow.yaml
+```
+
+## Examples
+
+### Basic Provider Removal
+
+**Before:**
+```jsx
+import {Provider, TitleBar} from '@shopify/app-bridge-react';
+
+export default function App() {
+  return (
+    <Provider config={{apiKey: 'old', host: 'host'}}>
+      <div>
+        <TitleBar title="Hello" />
+      </div>
+    </Provider>
+  );
+}
+```
+
+**After:**
+```jsx
+import { TitleBar } from '@shopify/app-bridge-react';
+
+export default function App() {
+  return (
+    <div>
+        <TitleBar title="Hello" />
+      </div>
+  );
+}
+```
+
+### Aliased Provider Removal
+
+**Before:**
+```jsx
+import {Provider as AppProvider, TitleBar} from '@shopify/app-bridge-react';
+
+export default function App() {
+  return (
+    <AppProvider config={{apiKey: 'old', host: 'host'}}>
+      <div>
+        <TitleBar title="Hello" />
+      </div>
+    </AppProvider>
+  );
+}
+```
+
+**After:**
+```jsx
+import { TitleBar } from '@shopify/app-bridge-react';
+
+export default function App() {
+  return (
+    <div>
+        <TitleBar title="Hello" />
+      </div>
+  );
+}
+```
+
+## Implementation
+
+This codemod uses JSSG (JavaScript Structural Grep) with AST-based transformations:
+- **AST node traversal** for finding and transforming import statements
+- **AST node traversal** for finding and unwrapping JSX elements
+- **Minimal regex** only for content extraction from JSX elements
+- **Pure AST patterns** for self-closing elements and React.createElement calls
+
