+# Dataset Preprocessing Specification
+
+This document defines the format for processed dataset subsets in JSONL format.
+
+---
+
+## Core Dataset Schema
+
+Each line in the JSONL file must contain a JSON object with the following fields:
+
+```json
+{
+  "id": "unique_identifier",
+  "images": ["path/to/image0.png", "path/to/image1.png"],
+  "messages": [...],
+  "tools": "none | POINT_TOOLS_LIST | BBOX_TOOLS_LIST | DESKTOP_USE_ATOMIC_TOOLS_LIST | MOBILE_USE_ATOMIC_TOOLS_LIST",
+  "resolution": [width, height],
+  "meta": {
+    "os": "none | ubuntu | windows | macos | android | ios",
+    ...
+  }
+}
+```
+
+### Field Descriptions
+
+- **`id`**: Unique identifier for each data sample
+- **`images`**: List of file paths to screenshot images
+- **`messages`**: Conversation turns in OpenAI-style message format
+- **`tools`**: Tool configuration (see [Tool Types](#tool-types) and `cua_lite/data/tools/atomic.py`)
+- **`resolution`**: Display resolution as `[width, height]`
+- **`meta`**: Metadata object containing:
+  - **`os`**: Operating system context (`none` for web-based, or specific OS)
+  - Additional custom metadata fields as needed
+
+### Tool Types
+
+The `tools` field specifies which tool set is available for the agent; Please find the definition of these tools in `cua_lite/data/tools/atomic.py`.
+
+| Tool Type | Description |
+|-----------|-------------|
+| `none` | No tools (understanding tasks only) |
+| `POINT_TOOLS_LIST` | Point-based interaction tools |
+| `BBOX_TOOLS_LIST` | Bounding box tools |
+| `DESKTOP_USE_ATOMIC_TOOLS_LIST` | Desktop atomic action tools |
+| `MOBILE_USE_ATOMIC_TOOLS_LIST` | Mobile atomic action tools |
+
+
+---
+
+## Dataset Task Types
+
+### Understanding Tasks
+
+Understanding tasks involve image comprehension without tool usage.
+
+**Configuration:**
+- **`tools`**: `none`
+- **`messages`**: `none`
+**Message Format Example:**
+
+```json
+{
+  "messages": [
+    {
+      "role": "user",
+      "content": [
+        {"type": "image", "index": 0},
+        {"type": "text", "text": "Please explain the first screenshot to me."}
+      ]
+    },
+    {
+      "role": "assistant",
+      "content": [
+        {"type": "text", "text": "This is a screenshot of a desktop."}
+      ]
+    }
+  ]
+}
+```
+
+**Notes:**
+- The `"index"` field in image content references the zero-based position in the `images` array
+- Multiple conversation turns are supported for follow-up questions
