 ### 使用目标 Agent 的独立工作区记录成果
-为了方便用户在对应 Agent 的文件面板中查阅训练资料，你和你委派的 3 个元 Agent（Hunter, Digester, Evolver）的**所有中间产出和过程记录，必须强制写入目标 Agent 自身的 `workspace/` 目录中**！
-当你 dispatch 任务给它们时，请明确告诉它们输出路径。
-示例：假设给你的目标 Agent 路经是 `system/templates/weibo-scraper`

+
+# YouTube Trending Crawler
+
+Fetch YouTube trending/popular videos using YouTube Data API v3.
+
+## Setup
+
+1. **API Key**: Get from [Google Cloud Console](https://console.cloud.google.com/apis/credentials) - enable YouTube Data API v3
+2. **Regions**: ISO 3166-1 alpha-2 codes (US, JP, KR, GB, DE, FR, IN, BR, etc.)
+3. **Categories**: Video category IDs (1=Film, 2=Autos, 10=Music, 17=Sports, 20=Gaming, 24=Entertainment, 28=Tech, etc.)
+
+## Core API
+
+### Primary: videos endpoint (1 quota unit)
+
+```bash
+# Most Popular Videos (CHART endpoint - 1 unit)
+curl "https://www.googleapis.com/youtube/v3/videos?part=snippet,statistics,contentDetails&chart=mostPopular&regionCode=US&videoCategoryId=10&maxResults=10&key=API_KEY"

Use when users want to (1) Get trending videos for a region, (2) Fetch popular videos by category, (3) Batch crawl multiple regions, (4) Monitor trending content across markets. Requires YouTube Data API v3 key."

-# YouTube Trending Crawler
-
-Fetch YouTube trending/popular videos using YouTube Data API v3.
-
-## Setup
-
-1. **API Key**: Get from [Google Cloud Console](https://console.cloud.google.com/apis/credentials) - enable YouTube Data API v3
-2. **Regions**: ISO 3166-1 alpha-2 codes (US, JP, KR, GB, DE, FR, IN, BR, etc.)
-3. **Categories**: Video category IDs (1=Film, 2=Autos, 10=Music, 17=Sports, 20=Gaming, 24=Entertainment, 28=Tech, etc.)
-
-## Core API
-
-### Primary: videos endpoint (1 quota unit)
-
-```bash
-# Most Popular Videos (CHART endpoint - 1 unit)
-curl "https://www.googleapis.com/youtube/v3/videos?part=snippet,statistics,contentDetails&chart=mostPopular&regionCode=US&videoCategoryId=10&maxResults=10&key=API_KEY"
-
-# Batch video IDs (max 50 per call)
-curl "https://www.googleapis.com/youtube/v3/videos?part=snippet,statistics,contentDetails&id=VIDEO_IDS&key=API_KEY"
-```
-
-### Fallback: yt-dlp (when API fails)
-
-```bash
-# Get trending page
-yt-dlp "https://www.youtube.com/results?sp=CAA%253D&q=trending" --flat-playlist --print "%(id)s|%(title)s|%(channel_id)s|%(channel)s|%(view_count)s|%(like_count)s|%(comment_count)s|%(upload_date)s|%(description)s|%(thumbnail)s|%(categories)s|%(duration)s"
-
-# Get specific video details
-yt-dlp "https://youtube.com/watch?v=VIDEO_ID" --print "%(id)s|%(title)s|%(channel_id)s|%(channel)s|%(view_count)s|%(like_count)s|%(comment_count)s|%(upload_date)s|%(description)s|%(thumbnail)s|%(categories)s|%(duration)s|%(tags)s"

-## Error Handling
-
-### 403 Quota Exceeded
-```javascript
-if (error.code === 403 && error.message.includes('quota')) {
-  // Fallback to yt-dlp
-  return await fetchWithYtDlp(params);
-}
-```
-
-### 404 Video Not Found
-```javascript
-if (error.code === 404) {
-  console.log(`Video ${videoId} not found, skipping`);
-  return null;
-}
-```
-
-### 500 Server Error
-```javascript
-// Exponential backoff retry
-const maxRetries = 3;
-for (let i = 0; i < maxRetries; i++) {
-  try {
-    return await fetch(...);
-  } catch (e) {
-    if (e.code === 500 && i < maxRetries - 1) {
-      await sleep(Math.pow(2, i) * 1000);  // 1s, 2s, 4s
-    }
-  }
-}
-```
-
-### Rate Limit (429)
-```javascript
-if (error.code === 429) {
-  // Wait and retry with longer delay
-  await sleep(60000); // 1 minute
-  return await fetch(...);
-}
-```
-
-## Quota Management
-
-- Use `videos?chart=mostPopular` endpoint (1 unit)
-- NEVER use `search` endpoint (100 units)
-- Batch video IDs (max 50 per call when extending)
-- Cache category names locally
-- Rate limit: min 1000ms between requests
-

-## Error Handling
-
-### 403 Quota Exceeded
-```javascript
-if (error.code === 403 && error.message.includes('quota')) {
-  // Fallback to yt-dlp
-  return await fetchWithYtDlp(params);
-}
-```
-
-### 404 Video Not Found
-```javascript
-if (error.code === 404) {
-  console.log(`Video ${videoId} not found, skipping`);
-  return null;
-}
-```
-
-### 500 Server Error
-```javascript
-// Exponential backoff retry
-const maxRetries = 3;
-for (let i = 0; i < maxRetries; i++) {
-  try {
-    return await fetch(...);
-  } catch (e) {
-    if (e.code === 500 && i < maxRetries - 1) {
-      await sleep(Math.pow(2, i) * 1000);  // 1s, 2s, 4s
-    }
-  }
-}
-```
-
-### Rate Limit (429)
-```javascript
-if (error.code === 429) {
-  // Wait and retry with longer delay
-  await sleep(60000); // 1 minute
-  return await fetch(...);
-}
-```
-
-## Quota Management
-
-- Use `videos?chart=mostPopular` endpoint (1 unit)
-- NEVER use `search` endpoint (100 units)
-- Batch video IDs (max 50 per call when extending)
-- Cache category names locally
-- Rate limit: min 1000ms between requests
