+Other clients may expose these tools directly or through tool search.

+`desktop_state` returns JSON text, including `windows`, `active_window`, `monitors`,
+and `input_socket_exists`. Parse its text content or the JSON string in
+`structuredContent.result`; the latter is not already a desktop-state object.
+Check `isError` before using any tool result.

+Screenshots return both geometry text and an image content block. Forward the
+image to the model's image viewer, rather than printing the entire result as text
+or dumping its base64. For example, inside `functions.exec`, after selecting and
+focusing a window and assigning its address to `address`:
+
+```js
+const result = await tools.mcp__hyprland_desktop__screenshot({ address });
+if (result.isError) {

+    else if (block.type === "text") text(block.text);

+Inspect the emitted image before the next input call. Keep desktop operations
+sequential; calls that change focus or inject input must not run in parallel.
