 **Scaffolding is owned by the Wix CLI.** For every extension type except Backend API, files, folders, builder boilerplate, UUIDs, and `src/extensions.ts` registration are generated by `wix generate --params`.

+# Extension Deletion
+
+Covers safe deletion of any extension type from a Wix CLI project: dashboard pages, modals, plugins, menu plugins, service plugins, event extensions, data collections, backend APIs, editor React components, custom element widgets, site plugins, and embedded scripts.
+
+**Scaffolding teardown is manual.** Unlike creation (which uses `wix generate`), there is no CLI command to delete an extension.
+
+> ⚠️ **Always confirm with the user which extension(s) to delete before proceeding. Do not assume or decide on behalf of the user.** Check for dependent extensions — e.g., if a dashboard page that calls `dashboard.openModal()` is being deleted, ask whether the target modal should also be deleted.
+
+## Extension Types Reference Table
+
+| Extension Type | Category | Default Folder | Deviation |
+| --- | --- | --- | --- |
+| Dashboard Page | Dashboard | `src/extensions/dashboard/pages/<folder>/` | — |
+| Dashboard Modal | Dashboard | `src/extensions/dashboard/modals/<folder>/` | — |
+| Dashboard Plugin | Dashboard | `src/extensions/dashboard/plugins/<folder>/` | — |
+| Dashboard Menu Plugin | Dashboard | `src/extensions/dashboard/menu-plugins/<folder>/` | — |
+| Service Plugin | Backend | `src/extensions/backend/service-plugins/<folder>/` | — |
+| Backend Event Extension | Backend | `src/extensions/backend/events/<folder>/` | — |
+| Data Collection — single collection | Backend | — | See [Data Collection](#data-collection) |
+| Data Collection — entire extension | Backend | `src/extensions/backend/data-collections/<folder>/` | — |
+| Backend API (HTTP endpoint) | Backend | `src/pages/api/` | See [Backend API](#backend-api-http-endpoint) |
+| Editor React Component | Site | `src/extensions/site/editor-react-components/<folder>/` | — |
+| Custom Element Widget | Site | `src/extensions/site/custom-elements/<folder>/` | — |
+| Site Plugin | Site | `src/extensions/site/site-plugins/<folder>/` | See [Site Plugin](#site-plugin) |
+| Embedded Script | Site | `src/extensions/site/embedded-scripts/<folder>/` | — |
+
+> **⚠️ Backend API is the only extension type with no `extensions.ts` registration.** Deletion requires file removal only — no `extensions.ts` changes needed.
+
+> **Note:** If extension files were moved after generation, locate the actual folder from the `import` statement in `src/extensions.ts`.
+
+## Extension-Specific Steps
+
+### Data Collection
+
+Two distinct deletion modes — confirm with the user which one applies.
+
+**Mode A — Delete a single collection (keep the extension):**
+
+1. Open `src/extensions/backend/data-collections/<folder>/data-collections.extension.ts`.
+2. Delete the `import` for the collection schema file being deleted.
+3. Delete the corresponding entry from the `collections` array in the extension config.
+4. Delete the collection's schema file (e.g., `<collection-name>.ts`) from the folder.
+5. Do **not** touch `src/extensions.ts` — the Data Collection extension itself remains registered.
+
+**Mode B — Delete the entire Data Collection extension:**
+
+Follow the [common deletion steps](#common-deletion-steps) to delete the full folder and its entry from `src/extensions.ts`.
+
+> ⚠️ **Warning:** Deleting a data collection extension from a published app does not delete existing CMS data on installed sites. Communicate this to the user.
+
+### Backend API (HTTP Endpoint)
+
+Backend APIs are **never registered in `src/extensions.ts`** — auto-discovered by the Astro runtime from `src/pages/api/`.
+
+1. Delete the relevant `*.ts` file(s) from `src/pages/api/`.
+2. No `extensions.ts` changes are needed.
+
+### Site Plugin
+
+In addition to the common deletion steps, a Site Plugin stores a logo asset that must also be deleted:
+
+1. Delete the extension folder (common step 1).
+2. Delete the `import` + `.use()` from `src/extensions.ts` (common step 2).
+3. Delete the plugin's logo SVG from `public/` (e.g., `public/<plugin-name>-logo.svg`).
+
+## Common Deletion Steps
+
+Applies to all extension types **except** Backend API and single Data Collection deletion. Check [Extension-Specific Steps](#extension-specific-steps) first.
+
+**Step 1 — Delete the extension folder** using the path from the Extension Types Reference Table above.
+
+**Step 2 — Delete from `src/extensions.ts`** — remove both:
+1. The `import` statement for the extension
+2. The `.use(<extensionName>)` call that registers it
+
+**Example — before (deleting `myModal`):**
+```typescript
+import { app } from '@wix/astro/builders';
+import myPage from './extensions/dashboard/pages/my-page/my-page.extension.ts';
+import myModal from './extensions/dashboard/modals/my-modal/my-modal.extension.ts';
+
+export default app()
+  .use(myPage)
+  .use(myModal);
+```
+
+**After:**
+```typescript
+import { app } from '@wix/astro/builders';
+import myPage from './extensions/dashboard/pages/my-page/my-page.extension.ts';
+
+export default app()
+  .use(myPage);
+```
+
+When deleting multiple extensions, make all `src/extensions.ts` edits in a single pass to avoid intermediate broken states.
+
+## Validation
+
+Execute sequentially after all deletion steps are complete. Stop and report errors if either step fails.
+
+1. **TypeScript compilation** — `npx tsc --noEmit`. If errors remain, search for leftover references to the deleted extension in other files and delete them.
+2. **Build** — `npx wix build`. Check `.wix/debug.log` on failure.
+
+## Post-Deletion Requirements
+
+After completing deletion, the project must be rebuilt and re-deployed:
+
+| Category | Headless project | App project |
+| --- | --- | --- |
+| Dashboard extensions | Build + deploy | Build + deploy |
+| Backend extensions | Build + deploy | Build + deploy |
+| Site extensions | N/A (app-only) | **Release a new app version** |
+
+> **Site extensions note:** `wix release` is required — not just `wix build` + deploy — so the extension is deleted from all installed sites.
+
+Communicate the appropriate requirement to the user as a manual action item.
+
+## Cost Optimization
+
+- **Validate once** — run validation after all extensions are deleted, not after each individual deletion
+- **Single-pass `extensions.ts` edits** — batch all `import` and `.use()` deletions in one edit when deleting multiple extensions
+- **Skip `extensions.ts` for Backend API** — HTTP endpoints are never registered there; no edit needed
+- **Check the `import` path first** — always locate the actual folder from `extensions.ts` before deleting, in case files were moved after generation
