Instructions

Step 1: Fetch Video Data and Comments

For each video URL provided:

1. Extract the video ID
2. Fetch video metadata (title, channel, view count, like count, comment count):

curl -s "https://www.googleapis.com/youtube/v3/videos?part=snippet,statistics&id=${VIDEO_ID}&key=${YOUTUBE_API_KEY}"

3. Fetch all comments (paginate with

   pageToken

   to get up to 500):

curl -s "https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&videoId=${VIDEO_ID}&maxResults=100&order=relevance&key=${YOUTUBE_API_KEY}"

Step 2: Analyze Comments

Use the same analysis approach as the YouTube Comment Analyzer skill:

• Send comments in batches of 15 to

  claude-haiku-4-5-20251001

• Use the 5-layer scoring model (semantic 50%, video_relevance 15%, entity 15%, intent 10%, context 10%)
• Classify each comment into business categories
• Compute brand relevance scores and determine brand-relevant vs irrelevant

Step 3: Generate Aggregate Statistics

Compute the following metrics from the analyzed comments:

Overview Metrics:
- total_comments: total comments analyzed
- brand_relevant_count: comments passing relevance threshold
- brand_relevance_rate: relevant / total (%)
- sentiment_distribution: { positive, neutral, negative, toxic } counts and %
- category_distribution: { purchase_intent, product_question, brand_risk, competitor_mention, positive_feedback, negative_feedback, irrelevant } counts

Effectiveness Scores (0-100):
- engagement_quality: weighted score based on brand-relevant comment ratio and sentiment
- purchase_signal_strength: purchase_intent count normalized by total comments
- risk_level: brand_risk count normalized, inverted (lower risk = higher score)
- audience_alignment: how well the audience matches the brand's target

KOL-Specific Metrics:
- channel_title: KOL/channel name
- video_title: video title
- view_count, like_count, comment_count: raw YouTube stats
- comment_engagement_rate: comment_count / view_count (%)
- high_priority_comments: comments needing immediate attention
- unanswered_questions: product_question comments without replies

Step 4: Generate AI Summary with Claude

After computing statistics, send the aggregate data to Claude for a narrative summary.

Model:

claude-haiku-4-5-20251001

System Prompt:

You are an expert KOL marketing analyst. Given comment analysis data from a sponsored YouTube video, write a concise, actionable ROI report.

Focus on:
1. Overall collaboration effectiveness (1-10 score with justification)
2. Audience-brand alignment (do viewers care about the product?)
3. Key opportunities (purchase intent, product questions to answer)
4. Risk alerts (brand risks, competitor mentions, negative sentiment)
5. Actionable recommendations (3-5 specific next steps)

Be data-driven. Reference specific numbers. Be honest — if the collaboration performed poorly, say so clearly.

Write in {language}. Be concise but thorough.

Step 5: Format the Report
