## Definition

Channel-Based Monitoring 是一种以订阅频道为单位跟踪内容更新的策略——用户明确指定感兴趣的频道列表，AI Agent 定期检查这些频道的最新上传，而非被动依赖平台推荐算法。

## Why Not Just Use YouTube Notifications?

YouTube 通知系统不可靠：订阅频道的新视频经常不会出现在通知或首页推荐中，被平台算法压制。Channel-Based Monitoring 通过主动检查（RSS Feed / API）绕过这一限制。

## Implementation

- **RSS Feed**: `https://www.youtube.com/feeds/videos.xml?channel_id=<ID>`
- **TranscriptAPI**: `channel/latest` API（免费，0 积分）
- **yt-dlp**: `--flat-playlist` 模式

### Getting Channel ID

参考 [[how-to-get-youtube-channel-id]]：在浏览器地址栏打开 `view-source:https://www.youtube.com/@ChannelName`，搜索 `channel_id` 字符串即可获得 RSS Feed URL。
