+## 创建智能体
+
+使用 `veadk create` 命令在当前目录中创建一个新的智能体项目脚手架。
+
+```bash
+veadk create [OPTIONS]
+```
+
+选项包括：
+
+- `--agent-name`：智能体的名称。如果未提供，将会提示您输入。
+- `--ark-api-key`：ARK API 密钥。如果未提供，将会提示您输入或稍后在 `config.yaml` 文件中配置。
+
+执行 `veadk create` 命令后，它会：
+
+1.  提示您输入智能体名称（如果未通过 `--agent-name` 提供）。
+2.  提示您输入 ARK API 密钥（如果未通过 `--ark-api-key` 提供），您可以选择立即输入或稍后在生成的 `config.yaml` 文件中手动配置。
+3.  在当前目录下创建一个以智能体名称命名的新目录。
+4.  在新目录中生成以下文件：
+    *   `config.yaml`: 包含模型配置和日志级别的配置文件。
+    *   `{agent_name}/__init__.py`: 包初始化文件。
+    *   `{agent_name}/agent.py`: 智能体的主要逻辑文件，包含一个基本的 `Agent` 定义。
+
+如果目标目录已存在且不为空，它会提示您是否要覆盖它。
+
