App Setup

Prepares the Lichtblick web app for documentation screenshots by loading a layout or installing an extension via Playwright MCP.

Run these steps after verifying the app is running at http://localhost:8080 (see the screenshot-workflow skill) and before taking any screenshots.

Load a Layout

1. Open the layout menu

   Use browser_snapshot to inspect the page, then click the layout name shown in the top navigation bar (it displays the current layout name, e.g. Default).

   browser_click → layout name button in the top bar
   

2. Open the import dialog

   In the layout panel that appears, click Import from file….

   browser_click → "Import from file…" menu item
   

3. Upload the layout file

   A file picker will open. Use browser_file_upload with the absolute path to the chosen layout file:

   paths: ["<absolute-path-to-docs>/sample-data/layouts/<chosen-layout>.json"]
   

4. Confirm the layout loaded

   Use browser_snapshot to verify the layout name in the top bar has changed to match the imported layout. If the app shows an error, check that the JSON file is a valid Lichtblick layout export.

Install an Extension

1. Open the Extensions panel

   Click the Extensions icon in the left sidebar (puzzle-piece icon), or open it via the top-right app menu → Extensions.

   browser_click → Extensions sidebar icon
   

2. Open the install dialog

   Click the Install local extension button (or the + / upload icon within the Extensions panel).

   browser_click → "Install local extension" button
   

3. Upload the extension file

   A file picker will open. Use browser_file_upload with the absolute path to the chosen extension:

   paths: ["<absolute-path-to-docs>/sample-data/extensions/<chosen-extension>.foxe"]
   

4. Confirm the extension is active

   Use browser_snapshot to verify the extension appears in the Extensions panel list with a status of Installed (or equivalent active state). Reload the page with browser_navigate to http://localhost:8080 if the extension requires a restart to activate.

Order of Operations

When both a layout and an extension are needed, always follow this order:

1. Install the extension
2. Reload the app (browser_navigate to http://localhost:8080)
3. Load the layout
4. Load the data file (see screenshot-workflow skill)
5. Take screenshots
