+# Tieba
+
+**Mode**: 🔐 Browser · **Domain**: `tieba.baidu.com`
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `opencli tieba hot` | Read Tieba trending topics |
+| `opencli tieba posts <forum>` | List threads in one forum |
+| `opencli tieba search <keyword>` | Search threads across Tieba |
+| `opencli tieba read <thread-id>` | Read one thread page |
+
+## Usage Examples
+
+```bash
+# Trending topics
+opencli tieba hot --limit 5
+
+# List forum threads
+opencli tieba posts 李毅 --limit 10
+
+# Search Tieba
+opencli tieba search 编程 --limit 10
+
+# Read one thread
+opencli tieba read 10163164720 --limit 10
+
+# Read page 2 of a thread
+opencli tieba read 10163164720 --page 2 --limit 10
+
+# JSON output
+opencli tieba hot -f json
+```
+
+## Notes
+
+- `tieba search` currently supports only `--page 1`
+- `tieba read --limit` counts reply rows; page 1 may also include the main post
+
+## Prerequisites
+
+- Chrome running and able to open `tieba.baidu.com`
+- [Browser Bridge extension](/guide/browser-bridge) installed
+- For `posts`, `search`, and `read`, a valid Tieba login session in Chrome is recommended
