# 音频提取与切分 (`las_audio_extract_and_split`)

当用户需要从视频中提取音轨,或将长音频按规则(如时长、静音)切分时使用本 Skill。

## 注意事项(⚠️ 必须遵守)
- 千万不要让用户输入 AccessKey 和 SecretKey。
- 下载文件只能使用 `las-cli tos download` 命令(兼容 tos 和非 tos 资源)。
- `las-cli operators call` 和 `las-cli price` 命令的输出结果非常重要,必须完整返回给用户。

## 工作流(严格按步骤执行)

复制此清单并跟踪进度:

```text
执行进度:
- [ ] Step 0: 前置检查
- [ ] Step 1: 初始化与准备
- [ ] Step 2: 预估价格
- [ ] Step 3: 执行任务并呈现结果
- [ ] Step 4: 失败排查
```

### Step 0: 前置检查

版本检查(必须):请执行 las-cli install 0.3.8。若 las-cli 命令不存在,则执行 npm i -g "@volcengine/las-cli@0.3.8"
- **新版本提醒**:请执行 `npm info @volcengine/las-cli version` 查看当前可用的最新 Skill 版本(`las-cli` 与 Skill 版本一一对应)。若返回版本高于本 Skill 标注版本,请先提示用户升级当前 Skill。升级方式:请用户发送自然语言指令 `帮我安装byted-las-audio-extract-and-split技能`,等待自动完成安装即可。
- **认证检查**:优先使用运行时自动注入的平台身份;若当前环境未自动注入,再运行 `las-cli config show` 确认旧版凭证 `las.apiKey` 和 `volcengine.region` 已配置。

### Step 1: 初始化与准备

- **上传资源**: 若输入为本地媒体文件,先上传到 TOS。
  ```bash
  las-cli tos upload ./input.mp4
  # 假设返回 "tos_url": "tos://my-bucket/inputs/xxx.mp4"
  ```
- **准备参数**: 创建 `params.json`,指定输入、输出及切分策略,注意 `output_path` 加上唯一标识,避免覆盖已存在文件。
  ```json
  {
    "input_path": "tos://my-bucket/inputs/xxx.mp4",
    "output_path": "tos://my-bucket/outputs/audio_split/",
    "split_mode": "duration",
    "split_duration": 60
  }
  ```

### Step 2: 预估价格(⚠️ 必须获得用户确认)

`las-cli price` 命令的输出结果非常重要,不要做任何精简、修改或摘要处理。

- **算价**: 必须完整返回以下命令输出的结果(markdown 格式)
  ```bash
  las-cli price las_audio_extract_and_split \
    --params-file ./params.json \
    --format markdown
  ```
- **用户确认**: 输出预估价格后,**必须等待用户确认**。

### Step 3: 执行任务并呈现结果(⚠️ 直接输出命令执行结果,不要精简)

`las-cli operators call` 命令的输出结果非常重要,不要做任何精简、修改或摘要处理。

- **执行**: 必须完整返回以下命令输出的结果(markdown 格式)
  ```bash
  las-cli operators call las_audio_extract_and_split \
    --params-file ./params.json \
    --format markdown \
    --out ./result.md
  ```

### Step 4: 失败排查

保持原样。

- **检查输入/输出**: 确认 TOS 路径是否存在、可读、可写。
- **检查配置**: `las-cli config show`。
- **查看帮助**: `las-cli operators help las_audio_extract_and_split`,检查切分参数。
