+
+Add Template Renderers plugin for auto-generated simplified template rendering APIs
+
+This new plugin reduces template rendering boilerplate by 70-80% by automatically generating pre-configured rendering functions. It follows the same architectural pattern as the typed templates system, with a TypeScript-specific renderer function (`renderTsTemplateRenderers`) that generates generic definitions consumed by the plugin.
+
+**Key Features:**
+
+- **Simplified API**: Reduces complex `renderTemplate`/`renderTemplateGroup` calls to simple `renderers.templateName.render()` calls
+- **Automatic Dependency Resolution**: Import map providers and task dependencies are automatically resolved
+- **Type Safety**: Generated interfaces provide full TypeScript type safety
+- **Generic Architecture**: Extensible to support future template types (text, raw, etc.)
+- **Backward Compatibility**: Existing generators continue working unchanged
+
+**Before:**
+
+```typescript
+await builder.apply(
+  typescriptFile.renderTemplateGroup({
+    group: templates.hooksGroup,
+    paths,
+    variables: { useCurrentUser: { TPL_USER: userQueryName } },
+    importMapProviders: { generatedGraphqlImports, reactErrorImports },
+  }),
+);
+```
+
+**After:**
+
+```typescript
+await builder.apply(
+  renderers.hooksGroup.render({
+    variables: { useCurrentUser: { TPL_USER: userQueryName } },
+  }),
+);
+```
+
+The plugin automatically generates TypeScript interfaces, tasks with resolved dependencies, and exports that integrate seamlessly with the existing generator system.
