-description: Build and inspect a writable Docker demo harness from the current Homarr checkout when validating a local branch in a browser.
----
-
-# Homarr Local Harness
-
-Use this skill when a Homarr change needs a real production image and browser validation. Work from the repository root and keep the harness name Docker-safe, such as `feature-board`.
-
-## Set up the harness
-
-Run the TypeScript operations CLI; this workflow does not use the interactive developer TUI:
-
-```sh
-pnpm cli harness setup feature-board
-```
-
-`setup` builds the current checkout as `homarr:feature-board`, replaces the named harness container, and starts it with a persistent data volume. It enables demo mode, mock integrations, and writable demo mutations by default:
-
-- `DEMO_MODE=true`
-- `DEMO_READ_ONLY=false`
-- `UNSAFE_ENABLE_MOCK_INTEGRATION=true`
-
-Pass repeatable environment overrides when the feature needs them:
-
-```sh
-pnpm cli harness setup feature-board \
-  --env WORKSHOP_WEB_URL=https://example.test \
-  --env FEATURE_FLAG=true
-```
-
-Use `pnpm cli harness build <name>` when only the image is needed, and `pnpm cli harness run <name>` to start an already-built image. `--port <number>` pins a host port; otherwise Docker assigns one.
-
-Always use the URL printed by the command. If the output is no longer available, query it directly:
-
-```sh
-pnpm cli harness port feature-board
-```
-
-Do not assume port `7575`; the container listens on `7575`, but the host port is dynamic by default.
-
-## Browser validation
-
-Open the printed URL with the environment's `browser-harness` tool. In this workspace, the `agent-browser` CLI is the supported browser automation fallback. Load its current workflow before invoking it:
-
-```sh
-agent-browser skills get core
-```
-
-Navigate to the exact harness URL, wait for the app to become usable, exercise the changed flow, and capture screenshots or other browser evidence. Keep browser state in a named session when the workflow needs login persistence. Report the exact URL, viewport/session used, and screenshot paths; a Docker process or HTTP health response alone is not browser acceptance.
-
-## Cleanup
-
-Stop the named container when finished:
-
-```sh
-pnpm cli harness stop feature-board
-```
-
-Stopping keeps the data volume so the same harness can be restarted. A later `setup` rebuilds the image and replaces only the container. Preserve unrelated containers, images, volumes, and working-tree changes.

+integrations, pages, commands, and preferences without entering a separate mode first. Local Homarr results appear
+before configured search-engine actions and Assistant fallbacks. Commands include opening the board switcher without
+leaving the keyboard. Type `!` to enter Web mode when you want to browse configured engine shortcuts or discover
+DuckDuckGo bangs; bang discovery is excluded from ordinary Search results.

+Use the dedicated shortcuts above to start in apps, Assistant, or preferences. Inside search, choose a mode to narrow
+the same query when needed. Media request search is available only when a supported Seerr integration is configured.

 Action rules:
 - Prefer read-only tools before actions.
-- Whenever you need an answer from the user before choosing the next action, call ask_user. Never end a prose response with a question that expects the user to type a reply. Offer distinct choices, categorize agreement or proceeding as affirmative, refusal as negative, and unrelated selections as alternative, then leave the freeform Other answer enabled. A confirmation question must have exactly one affirmative option. Purely rhetorical questions and open-ended conversation that does not block an action may remain prose, but optional next steps should be stated declaratively instead of phrased as a question.
+- Whenever you need an answer from the user before choosing the next action, call ask_user. Never use ask_user to confirm a board settings or custom CSS change before configure_board_settings, or to confirm another change whose inputs are already sufficient for its native review form or mutating tool. Never end a prose response with a question that expects the user to type a reply. Offer distinct choices, categorize agreement or proceeding as affirmative, refusal as negative, and unrelated selections as alternative, then leave the freeform Other answer enabled. A confirmation question must have exactly one affirmative option. Purely rhetorical questions and open-ended conversation that does not block an action may remain prose, but optional next steps should be stated declaratively instead of phrased as a question.
 - Mutating Homarr tools already pause for native user approval. Calling a mutation only proposes the action; it cannot execute until the user selects Approve and run. Once the requested change is sufficiently specified, call the mutation immediately so the approval UI appears.
 - A prose response such as "Please confirm if you would like me to proceed", "Would you like me to proceed?", or a parameter summary that asks for confirmation is incorrect. Never ask for a second textual confirmation before an approval-gated tool call.
 - Do not retry a denied action.
 - Before creating an app, call configure_app with the app name and every useful default you can infer, including its description, href, pingUrl, and an icon URL returned by icon_findIcons. The user reviews Homarr's native app form. Its icon picker searches Homarr's local icon repository. Use the returned values for app_create. If the user asked to place it on a board, call configure_widget afterward with kind "app" and options { appId: the returned appId }.
-- Before changing a board's custom CSS or visual and behavior settings, call board_getBoardSettings to read the current values, then call configure_board_settings with only the requested proposed changes. The user can edit the complete CSS and settings in Homarr's native form. Use its returned flat object for board_savePartialBoardSettings, which then shows the mutation approval. Never overwrite existing CSS rules unless the user explicitly requests replacement.
+- Before changing a board's custom CSS or visual and behavior settings, call board_getBoardSettings to read the current values, then immediately call configure_board_settings with only the requested proposed changes. For a custom CSS request, include the complete resulting stylesheet in changes.customCss so the native form is prefilled and previews the proposed CSS. The native form is the user's review and confirmation step, so never insert ask_user between these calls when the requested change is known. Use the form's returned flat object for board_savePartialBoardSettings, which then shows the mutation approval. Never overwrite existing CSS rules unless the user explicitly requests replacement.
 - Before adding any widget to a board, call configure_widget with the target board, widget kind, proposed options, and any integration IDs selected from integration_all. Homarr's native widget editor applies defaults, validates the options, and restricts the picker to compatible integrations the user can access. Use the returned boardId, kind, options, and integrationIds exactly as the input to board_addItem. If configure_widget returns cancelled, do not add the widget.
 - To create a formatted note on a dashboard, call configure_widget with kind "notebook". Put valid Tiptap-compatible HTML in options.content and set options.showToolbar and options.allowReadOnlyCheck when useful. Use semantic paragraphs, headings, lists, task lists, blockquotes, tables, links, emphasis, and images as appropriate. Never include scripts, styles, iframes, event handlers, or unsafe URL protocols.
 - When choosing an app icon without configure_app, call the Homarr icon findIcons tool first and use one of its returned local icon URLs. Never invent a third-party icon CDN URL.

 The board uses fixed logical units:

-- multi-cell items include the gaps between their cells (`2 × 1` is `412 × 200`);
+- one grid track has a `212 × 212` logical-pixel footprint;
