 # Repository Guidelines
 
 ## Project Structure & Module Organization
-- Source: `src/` (Vue 3 + TypeScript). Key areas: `components/`, `views/`, `stores/` (Pinia), `composables/`, `services/`, `utils/`, `assets/`, `locales/`.
-- Routing/i18n/entry: `src/router.ts`, `src/i18n.ts`, `src/main.ts`.
-- Tests: unit/component in `tests-ui/` and `src/components/**/*.{test,spec}.ts`; E2E in `browser_tests/`.
-- Public assets: `public/`. Build output: `dist/`.
-- Config: `vite.config.mts`, `vitest.config.ts`, `playwright.config.ts`, `eslint.config.ts`, `.prettierrc`.

+
+## Monorepo Architecture
+
+The project now uses **Nx** for build orchestration and task management:
+
+- **Task Orchestration**: Commands like `dev`, `build`, `lint`, and `test:browser` run via Nx
+- **Caching**: Nx provides intelligent caching for faster rebuilds
+- **Configuration**: Managed through `nx.json` with plugins for ESLint, Storybook, Vite, and Playwright
+- **Dependencies**: Nx handles dependency graph analysis and parallel execution
+
+Key Nx features:
+
+- Build target caching and incremental builds
+- Parallel task execution across the monorepo
+- Plugin-based architecture for different tools
 
 ## Build, Test, and Development Commands
+
 - `pnpm dev`: Start Vite dev server.
-- `pnpm dev:electron`: Dev server with Electron API mocks.
-- `pnpm build`: Type-check then production build to `dist/`.
-- `pnpm preview`: Preview the production build locally.
-- `pnpm test:unit`: Run Vitest unit tests.
-- `pnpm test:browser`: Run Playwright E2E tests (`browser_tests/`).
-- `pnpm lint` / `pnpm lint:fix`: Lint (ESLint). `pnpm format` / `format:check`: Prettier.
-- `pnpm typecheck`: Vue TSC type checking.

 ## Coding Style & Naming Conventions
-- Language: TypeScript, Vue SFCs (`.vue`). Indent 2 spaces; single quotes; no semicolons; width 80 (see `.prettierrc`).
-- Imports: sorted/grouped by plugin; run `pnpm format` before committing.
-- ESLint: Vue + TS rules; no floating promises; unused imports disallowed; i18n raw text restrictions in templates.
-- Naming: Vue components in PascalCase (e.g., `MenuHamburger.vue`); composables `useXyz.ts`; Pinia stores `*Store.ts`.
+
+- Language:
+  - TypeScript (exclusive, no new JavaScript)
+  - Vue 3 SFCs (`.vue`)
+    - Composition API only
+  - Tailwind 4 styling
+    - Avoid `<style>` blocks

 ## Testing Guidelines
-- Frameworks: Vitest (unit/component, happy-dom) and Playwright (E2E).
-- Test files: `**/*.{test,spec}.{ts,tsx,js}` under `tests-ui/`, `src/components/`, and `src/lib/litegraph/test/`.
-- Coverage: text/json/html reporters enabled; aim to cover critical logic and new features.
-- Playwright: place tests in `browser_tests/`; optional tags like `@mobile`, `@2x` are respected by config.
+
+- Frameworks:
+  - Vitest (unit/component, happy-dom)
+  - Playwright (E2E)
+- Test files:
+  - Unit/Component: `**/*.test.ts`
+  - E2E: `browser_tests/**/*.spec.ts`
+  - Litegraph Specific: `src/lib/litegraph/test/`
+- Coverage: text/json/html reporters enabled
+  - aim to cover critical logic and new features
+- Playwright:
+  - optional tags like `@mobile`, `@2x` are respected by config
 
 ## Commit & Pull Request Guidelines
-- Commits: Use `[skip ci]` for locale-only updates when appropriate.
-- PRs: Include clear description, linked issues (`- Fixes #123`), and screenshots/GIFs for UI changes.
-- Quality gates: `pnpm lint`, `pnpm typecheck`, and relevant tests must pass. Keep PRs focused and small.

 ## Security & Configuration Tips
+
 - Secrets: Use `.env` (see `.env_example`); do not commit secrets.
+
+## Vue 3 Composition API Best Practices
+
+- Use `<script setup lang="ts">` for component logic
+- Utilize `ref` for reactive state
+- Implement computed properties with computed()
+- Use watch and watchEffect for side effects
+  - Avoid using a `ref` and a `watch` if a `computed` would work instead
+- Implement lifecycle hooks with onMounted, onUpdated, etc.
+- Utilize provide/inject for dependency injection
+  - Do not use dependency injection if a Store or a shared composable would be simpler
+- Use Vue 3.5 TypeScript style of default prop declaration
+  - Example:
+
+    ```typescript
+    const { nodes, showTotal = true } = defineProps<{
+    nodes: ApiNodeCost[]
+    showTotal?: boolean
+    }>()
+    ```
+
+  - Do not use `withDefaults` or runtime props declaration
+  - Do not import Vue macros unnecessarily
+  - Prefer `useModel` to separately defining a prop and emit
+  - Be judicious with addition of new refs or other state
+    - If it's possible to accomplish the design goals with just a prop, don't add a `ref`
+    - If it's possible to use the `ref` or prop directly, don't add a `computed`
+    - If it's possible to use a `computed` to name and reuse a derived value, don't use a `watch`
+
+## Development Guidelines
+
+1. Leverage VueUse functions for performance-enhancing styles
+2. Use es-toolkit for utility functions
+3. Use TypeScript for type safety
+4. Implement proper props and emits definitions
+5. Utilize Vue 3's Teleport component when needed
+6. Use Suspense for async components
+7. Implement proper error handling
+8. Follow Vue 3 style guide and naming conventions
+9. Use Vite for fast development and building
+10. Use vue-i18n in composition API for any string literals. Place new translation entries in src/locales/en/main.json
+11. Avoid new usage of PrimeVue components

+
+## Project Philosophy
+
+- Follow good software engineering principles
+  - YAGNI
+  - AHA
+  - DRY
+  - SOLID
+- Clean, stable public APIs
+- Domain-driven design
+- Thousands of users and extensions
+- Prioritize clean interfaces that restrict extension access
+
+## Repository Navigation
+
+- Check README files in key folders (tests-ui, browser_tests, composables, etc.)
+- Prefer running single tests for performance
+- Use --help for unfamiliar CLI tools
+
+## GitHub Integration
+
+When referencing Comfy-Org repos:
+
+1. Check for local copy
+2. Use GitHub API for branches/PRs/metadata
+3. Curl GitHub website if needed
+
+## Settings and Feature Flags Quick Reference
+
+### Settings Usage
+
+```typescript
+const settingStore = useSettingStore()
+const value = settingStore.get('Comfy.SomeSetting')     // Get setting
+await settingStore.set('Comfy.SomeSetting', newValue)   // Update setting
+```
+
+### Dynamic Defaults
+
+```typescript
+{
+  id: 'Comfy.Example.Setting',
+  defaultValue: () => window.innerWidth < 1024 ? 'small' : 'large'  // Runtime context
+}
+```
+
+### Version-Based Defaults
+
+```typescript
+{
+  id: 'Comfy.Example.Feature',
+  defaultValue: 'legacy',
+  defaultsByInstallVersion: { '1.25.0': 'enhanced' }  // Gradual rollout
+}
+```
+
+### Feature Flags
+
+```typescript
+if (api.serverSupportsFeature('feature_name')) {  // Check capability
+  // Use enhanced feature
+}
+const value = api.getServerFeature('config_name', defaultValue)  // Get config
+```
+

+- Feature flags system: `docs/FEATURE_FLAGS.md`
+
+## Common Pitfalls
+
+- NEVER use `any` type - use proper TypeScript types
+- NEVER use `as any` type assertions - fix the underlying type issue
+- NEVER use `--no-verify` flag when committing
+- NEVER delete or disable tests to make them pass
+- NEVER circumvent quality checks
+- NEVER use `dark:` or `dark-theme:` tailwind variants. Instead use a semantic value from the `style.css` theme, e.g. `bg-node-component-surface`
+- NEVER use `:class="[]"` to merge class names - always use `import { cn } from '@/utils/tailwindUtil'`, for example: `<div :class="cn('text-node-component-header-icon', hasError && 'text-danger')" />`
