+- use npm run to see what commands are available
+- After making code changes, follow this general process: (1) Create unit tests, component tests, browser tests (if appropriate for each), (2) run unit tests, component tests, and browser tests until passing, (3) run typecheck, lint, format (with prettier) -- you can use `npm run` command to see the scripts available, (4) check if any READMEs (including nested) or documentation needs to be updated, (5) Decide whether the changes are worth adding new content to the external documentation for (or would requires changes to the external documentation) at https://docs.comfy.org, then present your suggestion
+- When referencing PrimeVue, you can get all the docs here: https://primevue.org. Do this instead of making up or inferring names of Components
+- When trying to set tailwind classes for dark theme, use "dark-theme:" prefix rather than "dark:"
+- Never add lines to PR descriptions that say "Generated with Claude Code"
+- When making PR names and commit messages, if you are going to add a prefix like "docs:", "feat:", "bugfix:", use square brackets around the prefix term and do not use a colon (e.g., should be "[docs]" rather than "docs:").
+- When I reference GitHub Repos related to Comfy-Org, you should proactively fetch or read the associated information in the repo. To do so, you should exhaust all options: (1) Check if we have a local copy of the repo, (2) Use the GitHub API to fetch the information; you may want to do this IN ADDITION to the other options, especially for reading speicifc branches/PRs/comments/reviews/metadata, and (3) curl the GitHub website and parse the html or json responses
+- For information about ComfyUI, ComfyUI_frontend, or ComfyUI-Manager, you can web search or download these wikis: https://deepwiki.com/Comfy-Org/ComfyUI-Manager, https://deepwiki.com/Comfy-Org/ComfyUI_frontend/1-overview, https://deepwiki.com/comfyanonymous/ComfyUI/2-core-architecture
+- If a question/project is related to Comfy-Org, Comfy, or ComfyUI ecosystem, you should proactively use the Comfy docs to answer the question. The docs may be referenced with URLs like https://docs.comfy.org
+- When operating inside a repo, check for README files at key locations in the repo detailing info about the contents of that folder. E.g., top-level key folders like tests-ui, browser_tests, composables, extensions/core, stores, services often have their own README.md files. When writing code, make sure to frequently reference these README files to understand the overall architecture and design of the project. Pay close attention to the snippets to learn particular patterns that seem to be there for a reason, as you should emulate those.
+- Prefer running single tests, and not the whole test suite, for performance
+- If using a lesser known or complex CLI tool, run the --help to see the documentation before deciding what to run, even if just for double-checking or verifying things.
+- IMPORTANT: the most important goal when writing code is to create clean, best-practices, sustainable, and scalable public APIs and interfaces. Our app is used by thousands of users and we have thousands of mods/extensions that are constantly changing and updating; and we are also always updating. That's why it is IMPORTANT that we design systems and write code that follows practices of domain-driven design, object-oriented design, and design patterns (such that you can assure stability while allowing for all components around you to change and evolve). We ABSOLUTELY prioritize clean APIs and public interfaces that clearly define and restrict how/what the mods/extensions can access.

+
+> **Desktop Users**: For issues specific to the desktop application, please refer to the [ComfyUI desktop repository](https://github.com/Comfy-Org/desktop).
+
+### Debugging Custom Node (Extension) Issues
+
+If you're experiencing crashes, errors, or unexpected behavior with ComfyUI, it's often caused by custom nodes (extensions). Follow these steps to identify and resolve the issues:
+
+#### Step 1: Verify if custom nodes are causing the problem
+
+Run ComfyUI with the `--disable-all-custom-nodes` flag:
+
+```bash
+python main.py --disable-all-custom-nodes
+```
+
+If the issue disappears, a custom node is the culprit. Proceed to the next step.
+
+#### Step 2: Identify the problematic custom node using binary search
+
+Rather than disabling nodes one by one, use this more efficient approach:
+
+1. Temporarily move half of your custom nodes out of the `custom_nodes` directory
+   ```bash
+   # Create a temporary directory
+   # Linux/Mac
+   mkdir ~/custom_nodes_disabled
+   
+   # Windows
+   mkdir %USERPROFILE%\custom_nodes_disabled
+   
+   # Move half of your custom nodes (assuming you have node1 through node8)
+   # Linux/Mac
+   mv custom_nodes/node1 custom_nodes/node2 custom_nodes/node3 custom_nodes/node4 ~/custom_nodes_disabled/
+   
+   # Windows
+   move custom_nodes\node1 custom_nodes\node2 custom_nodes\node3 custom_nodes\node4 %USERPROFILE%\custom_nodes_disabled\
+   ```
+
+2. Run ComfyUI again
+   - If the issue persists: The problem is in nodes 5-8 (the remaining half)
+   - If the issue disappears: The problem is in nodes 1-4 (the moved half)
+
+3. Let's assume the issue disappeared, so the problem is in nodes 1-4. Move half of these for the next test:
+   ```bash
+   # Move nodes 3-4 back to custom_nodes
+   # Linux/Mac
+   mv ~/custom_nodes_disabled/node3 ~/custom_nodes_disabled/node4 custom_nodes/
+   
+   # Windows
+   move %USERPROFILE%\custom_nodes_disabled\node3 %USERPROFILE%\custom_nodes_disabled\node4 custom_nodes\
+   ```
+
+4. Run ComfyUI again
+   - If the issue reappears: The problem is in nodes 3-4
+   - If issue still gone: The problem is in nodes 1-2
+
+5. Let's assume the issue reappeared, so the problem is in nodes 3-4. Test each one:
+   ```bash
+   # Move node 3 back to disabled
+   # Linux/Mac
+   mv custom_nodes/node3 ~/custom_nodes_disabled/
+   
+   # Windows
+   move custom_nodes\node3 %USERPROFILE%\custom_nodes_disabled\
+   ```
+
+6. Run ComfyUI again
+   - If the issue disappears: node3 is the problem
+   - If issue persists: node4 is the problem
+
+7. Repeat until you identify the specific problematic node
+
+#### Step 3: Update or replace the problematic node
+
+Once identified:
+1. Check for updates to the problematic custom node
+2. Consider alternatives with similar functionality
+3. Report the issue to the custom node developer with specific details
+
+### Common Issues and Solutions
+
+- **"Module not found" errors**: Usually indicates missing Python dependencies. Check the custom node's `requirements.txt` file for required packages and install them:
+  ```bash
+  pip install -r custom_nodes/problematic_node/requirements.txt
+  ```
+
+- **Frontend or Templates Package Not Updated**: After updating ComfyUI via Git, ensure you update the frontend dependencies:
+  ```bash
+  pip install -r requirements.txt
+  ```
+
+- **Can't Find Custom Node**: Make sure to disable node validation in ComfyUI settings.
+
+- **Error Toast About Workflow Failing Validation**: Report the issue to the ComfyUI team. As a temporary workaround, disable workflow validation in settings.
+
+- **Login Issues When Not on Localhost**: Normal login is only available when accessing from localhost. If you're running ComfyUI via LAN, another domain, or headless, you can use our API key feature to authenticate. The API key lets you log in normally through the UI. Generate an API key at [platform.comfy.org/login](https://platform.comfy.org/login) and use it in the API Key field in the login dialog or with the `--api-key` command line argument. Refer to our [API Key Integration Guide](https://docs.comfy.org/essentials/comfyui-server/api-key-integration#integration-of-api-key-to-use-comfyui-api-nodes) for complete setup instructions.

+
+## Test Structure
+
+Browser tests in this project follow a specific organization pattern:
+
+- **Fixtures**: Located in `fixtures/` - These provide test setup and utilities
+  - `ComfyPage.ts` - The main fixture for interacting with ComfyUI
+  - `ComfyMouse.ts` - Utility for mouse interactions with the canvas
+  - Components fixtures in `fixtures/components/` - Page object models for UI components
+
+- **Tests**: Located in `tests/` - The actual test specifications
+  - Organized by functionality (e.g., `widget.spec.ts`, `interaction.spec.ts`)
+  - Snapshot directories (e.g., `widget.spec.ts-snapshots/`) contain reference screenshots
+
+- **Utilities**: Located in `utils/` - Common utility functions
+  - `litegraphUtils.ts` - Utilities for working with LiteGraph nodes
+
+## Writing Effective Tests
+
+When writing new tests, follow these patterns:
+
+### Test Structure
+
+```typescript
+// Import the test fixture
+import { comfyPageFixture as test } from '../fixtures/ComfyPage';
+
+test.describe('Feature Name', () => {
+  // Set up test environment if needed
+  test.beforeEach(async ({ comfyPage }) => {
+    // Common setup
+  });
+
+  test('should do something specific', async ({ comfyPage }) => {
+    // Test implementation
+  });
+});
+```
+
+### Leverage Existing Fixtures and Helpers
+
+Always check for existing helpers and fixtures before implementing new ones:
+
+- **ComfyPage**: Main fixture with methods for canvas interaction and node management
+- **ComfyMouse**: Helper for precise mouse operations on the canvas
+- **Helpers**: Check `browser_tests/helpers/` for specialized helpers like:
+  - `actionbar.ts`: Interact with the action bar
+  - `manageGroupNode.ts`: Group node management operations
+  - `templates.ts`: Template workflows operations
+- **Component Fixtures**: Check `browser_tests/fixtures/components/` for UI component helpers
+- **Utility Functions**: Check `browser_tests/utils/` and `browser_tests/fixtures/utils/` for shared utilities
+
+Most common testing needs are already addressed by these helpers, which will make your tests more consistent and reliable.
+
+### Key Testing Patterns
+
+1. **Focus elements explicitly**:
+   Canvas-based elements often need explicit focus before interaction:
+   ```typescript
+   // Click the canvas first to focus it before pressing keys
+   await comfyPage.canvas.click();
+   await comfyPage.page.keyboard.press('a');
+   ```
+
+2. **Mark canvas as dirty if needed**:
+   Some interactions need explicit canvas updates:
+   ```typescript
+   // After programmatically changing node state, mark canvas dirty
+   await comfyPage.page.evaluate(() => {
+     window['app'].graph.setDirtyCanvas(true, true);
+   });
+   ```
+
+3. **Use node references over coordinates**: 
+   Node references from `fixtures/utils/litegraphUtils.ts` provide stable ways to interact with nodes:
+   ```typescript
+   // Prefer this:
+   const node = await comfyPage.getNodeRefsByType('LoadImage')[0];
+   await node.click('title');
+   
+   // Over this:
+   await comfyPage.canvas.click({ position: { x: 100, y: 100 } });
+   ```
+
+4. **Wait for canvas to render after UI interactions**:
+   ```typescript
+   await comfyPage.nextFrame();
+   ```
+
+5. **Clean up persistent server state**:
+   While most state is reset between tests, anything stored on the server persists:
+   ```typescript
+   // Reset settings that affect other tests (these are stored on server)
+   await comfyPage.setSetting('Comfy.ColorPalette', 'dark');
+   await comfyPage.setSetting('Comfy.NodeBadge.NodeIdBadgeMode', 'None');
+   
+   // Clean up uploaded files if needed
+   await comfyPage.request.delete(`${comfyPage.url}/api/delete/image.png`);
+   ```
+
+6. **Prefer functional assertions over screenshots**:
+   Use screenshots only when visual verification is necessary:
+   ```typescript
+   // Prefer this:
+   expect(await node.isPinned()).toBe(true);
+   expect(await node.getProperty('title')).toBe('Expected Title');
+   
+   // Over this - only use when needed:
+   await expect(comfyPage.canvas).toHaveScreenshot('state.png');
+   ```
+
+7. **Use minimal test workflows**:
+   When creating test workflows, keep them as minimal as possible:
+   ```typescript
+   // Include only the components needed for the test
+   await comfyPage.loadWorkflow('single_ksampler');
+   ```
+
+## Common Patterns and Utilities
+
+### Page Object Pattern
+
+Tests use the Page Object pattern to create abstractions over the UI:
+
+```typescript
+// Using the ComfyPage fixture
+test('Can toggle boolean widget', async ({ comfyPage }) => {
+  await comfyPage.loadWorkflow('widgets/boolean_widget')
+  const node = (await comfyPage.getFirstNodeRef())!
+  const widget = await node.getWidget(0)
+  await widget.click()
+});
+```
+
+### Node References
+
+The `NodeReference` class provides helpers for interacting with LiteGraph nodes:
+
+```typescript
+// Getting node by type and interacting with it
+const nodes = await comfyPage.getNodeRefsByType('LoadImage')
+const loadImageNode = nodes[0]
+const widget = await loadImageNode.getWidget(0)
+await widget.click()
+```
+
+### Visual Regression Testing
+
+Tests use screenshot comparisons to verify UI state:
+
+```typescript
+// Take a screenshot and compare to reference
+await expect(comfyPage.canvas).toHaveScreenshot('boolean_widget_toggled.png')
+```
+
+### Waiting for Animations
+
+Always call `nextFrame()` after actions that trigger animations:
+
+```typescript
+await comfyPage.canvas.click({ position: { x: 100, y: 100 } })
+await comfyPage.nextFrame() // Wait for canvas to redraw
+```
+
+### Mouse Interactions
+
+Canvas operations use special helpers to ensure proper timing:
+
+```typescript
+// Using ComfyMouse for drag and drop
+await comfyMouse.dragAndDrop(
+  { x: 100, y: 100 },  // From
+  { x: 200, y: 200 }   // To
+)
+
+// Standard ComfyPage helpers
+await comfyPage.drag({ x: 100, y: 100 }, { x: 200, y: 200 })
+await comfyPage.pan({ x: 200, y: 200 })
+await comfyPage.zoom(-100) // Zoom in
+```
+
+### Workflow Management
+
+Tests use workflows stored in `assets/` for consistent starting points:
+
+```typescript
+// Load a test workflow
+await comfyPage.loadWorkflow('single_ksampler')
+
+// Wait for workflow to load and stabilize
+await comfyPage.nextFrame()
+```
+
+### Custom Assertions
+
+The project includes custom Playwright assertions through `comfyExpect`:
+
+```typescript
+// Check if a node is in a specific state
+await expect(node).toBePinned()
+await expect(node).toBeBypassed()
+await expect(node).toBeCollapsed()
+```
+
+## Troubleshooting Common Issues
+
+### Flaky Tests
+
+- **Timing Issues**: Always wait for animations to complete with `nextFrame()`
+- **Coordinate Sensitivity**: Canvas coordinates are viewport-relative; use node references when possible
+- **Test Isolation**: Tests run in parallel; avoid dependencies between tests
+- **Screenshots vary**: Ensure your OS and browser match the reference environment (Linux)
+- **Async / await**: Race conditions are a very common cause of test flakiness
+
 ## Screenshot Expectations
 
 Due to variations in system font rendering, screenshot expectations are platform-specific. Please note:
 
-- We maintain Linux screenshot expectations as our GitHub Action runner operates in a Linux environment.
-- To set new test expectations:
-  1. Create a pull request from a `Comfy-Org/ComfyUI_frontend` branch.
-  2. Add the `New Browser Test Expectation` tag to your pull request.
-  3. This will trigger a GitHub action to update the screenshot expectations automatically.
+- **DO NOT commit local screenshot expectations** to the repository
+- We maintain Linux screenshot expectations as our GitHub Action runner operates in a Linux environment
+- While developing, you can generate local screenshots for your tests, but these will differ from CI-generated ones
 
-> **Note:** If you're making a pull request from a forked repository, the GitHub action won't be able to commit updated screenshot expectations directly to your PR branch.
+To set new test expectations for PR:
+
+1. Write your test with screenshot assertions using `toHaveScreenshot(filename)`
+2. Create a pull request from a `Comfy-Org/ComfyUI_frontend` branch
+3. Add the `New Browser Test Expectation` tag to your pull request
+4. The GitHub CI will automatically generate and commit the reference screenshots
+
+This approach ensures consistent screenshot expectations across all PRs and avoids issues with platform-specific rendering.
+
+> **Note:** If you're making a pull request from a forked repository, the GitHub action won't be able to commit updated screenshot expectations directly to your PR branch.
