Reddit Sentiment Analysis Skill

Purpose

This skill enables systematic sentiment analysis of Reddit discussions to understand community opinions, preferences, and desires about products, brands, games, companies, or any topic. It produces actionable insights about what people like, what they criticize, and what improvements they wish for.

When to Use This Skill

Use this skill when you need to:

• Analyze community sentiment about games, products, or brands
• Understand what features/aspects users appreciate
• Identify common complaints and pain points
• Discover what improvements or changes users desire
• Generate competitive intelligence from community discussions
• Track sentiment trends over time for a topic
• Make data-driven product decisions based on user feedback

Prerequisites

This skill requires the Reddit MCP server to be configured in .mcp.json:

{
  "mcpServers": {
    "reddit": {
      "command": "uvx",
      "args": ["mcp-server-reddit"]
    }
  }
}

Core Workflow

Phase 1: Target Identification and Data Collection

1. Define Analysis Target

• Identify the product/brand/game/topic to analyze
• Determine relevant subreddits (e.g., r/gaming, r/Games, product-specific subs)
• Set time frame (recent posts, top posts from month/year)
• Define scope (how many posts/comments to analyze)

2. Collect Reddit Data

• Use mcp__reddit__get_subreddit_hot_posts for trending discussions
• Use mcp__reddit__get_subreddit_top_posts for highly-rated content
• Use mcp__reddit__get_post_content for detailed post + comments
• Collect minimum 10-20 posts for meaningful analysis
• Include both posts and top-level comments

Phase 2: Sentiment Classification

3. Analyze Each Discussion

For each post and comment, classify sentiment into:

POSITIVE Signals:

• Explicit praise: "I love...", "amazing", "best", "fantastic"
• Recommendations: "highly recommend", "must-try", "worth it"
• Emotional positivity: "fun", "enjoyable", "satisfying", "addicting"
• Problem solutions: "finally fixed", "works great now"
• Comparative praise: "better than X", "superior to"

NEGATIVE Signals:

• Explicit criticism: "hate", "terrible", "worst", "awful"
• Disappointment: "let down", "expected more", "overhyped"
• Problems: "broken", "doesn't work", "buggy", "crashes"
• Frustration: "annoying", "frustrating", "ridiculous"
• Regret: "waste of money", "not worth it", "refunded"

NEUTRAL Signals:

• Questions without sentiment
• Factual statements
• Technical discussions
• Requests for information

WISH/DESIRE Signals:

• "I wish...", "they should...", "would be better if..."
• "needs more...", "lacking...", "missing..."
• "hope they add...", "waiting for..."
• Feature requests and suggestions

Phase 3: Entity and Aspect Extraction

4. Identify Specific Aspects Mentioned

Extract what specifically is being discussed:

• Features: gameplay mechanics, UI/UX, specific capabilities
• Performance: speed, stability, optimization, bugs
• Content: story, levels, variety, depth
• Value: pricing, monetization, cost-benefit
• Support: customer service, updates, community engagement
• Comparisons: versus competitors, previous versions

Phase 4: Aggregation and Summarization

5. Create Structured Summary

Generate output in this format:

Implementation Protocol

Step 1: Create Todo List

TodoWrite([
  "Identify target subreddits for analysis",
  "Collect hot posts from subreddit(s)",
  "Collect top posts from time period",
  "Fetch detailed post content and comments",
  "Classify sentiment for each post/comment",
  "Extract aspects and entities mentioned",
  "Aggregate positive sentiment patterns",
  "Aggregate negative sentiment patterns",
  "Aggregate wish/desire patterns",
  "Calculate sentiment percentages",
  "Generate structured summary report"
])

Step 2: Parallel Data Collection

CRITICAL: Batch all Reddit API calls in a single message:

[Single Message - All Data Collection]:
  mcp__reddit__get_subreddit_hot_posts({subreddit_name: "gaming", limit: 20})
  mcp__reddit__get_subreddit_top_posts({subreddit_name: "gaming", time: "month", limit: 20})
  mcp__reddit__get_subreddit_hot_posts({subreddit_name: "Games", limit: 20})
  mcp__reddit__get_subreddit_top_posts({subreddit_name: "Games", time: "month", limit: 20})

Step 3: Parallel Comment Analysis

For each relevant post ID, fetch details in parallel:

[Single Message - All Post Details]:
  mcp__reddit__get_post_content({post_id: "abc123", comment_depth: 3, comment_limit: 20})
  mcp__reddit__get_post_content({post_id: "def456", comment_depth: 3, comment_limit: 20})
  mcp__reddit__get_post_content({post_id: "ghi789", comment_depth: 3, comment_limit: 20})
  // ... up to 10-20 posts in parallel

Step 4: Sentiment Analysis Engine

For each piece of content (post title, post body, comment):

1. Tokenize and normalize text

- Convert to lowercase - Remove URLs, special characters - Identify key phrases

1. Apply sentiment scoring function analyzeSentiment(text) {const positive_score = countMatches(text, POSITIVE_KEYWORDS); const negative_score = countMatches(text, NEGATIVE_KEYWORDS); const wish_score = countMatches(text, WISH_KEYWORDS); return {sentiment: determineOverallSentiment(positive_score, negative_score), confidence: calculateConfidence(positive_score, negative_score), wishes: wish_score > 0, aspects: extractAspects(text)};}
2. Extract context and aspects

- What noun/feature is being discussed? - What adjectives describe it? - What verbs indicate action/desire?

Step 5: Generate Report

Save the structured summary to /docs/reddit-sentiment-analysis-[topic]-[date].md

User: "What do people think about Tesla on Reddit?"

Agent workflow:
1. Create todos for brand analysis
2. Identify subreddits: r/teslamotors, r/electricvehicles, r/cars
3. Collect discussions mentioning "Tesla" (100 posts)

Best Practices

DO:

• ✅ Analyze multiple subreddits for balanced perspective
• ✅ Include both hot and top posts for recency + quality
• ✅ Read comments, not just post titles (comments have rich sentiment)
• ✅ Provide direct quotes as evidence
• ✅ Quantify sentiment with percentages and counts
• ✅ Organize by aspect/feature, not just positive/negative
• ✅ Save reports to /docs/ directory
• ✅ Batch all API calls in single messages

DON'T:

• ❌ Only analyze one subreddit (bias risk)
• ❌ Ignore comment sentiment (posts alone insufficient)
• ❌ Make claims without quote evidence
• ❌ Mix multiple products in one analysis (confusing)
• ❌ Save reports to root directory
• ❌ Make sequential API calls (use parallel batching)

Advanced Features

Temporal Sentiment Tracking

Compare sentiment across time periods:

[Parallel Time-Based Analysis]:
  get_subreddit_top_posts({time: "week"})
  get_subreddit_top_posts({time: "month"})
  get_subreddit_top_posts({time: "year"})

Generate trend report showing sentiment evolution.

Competitive Benchmarking

Analyze multiple products simultaneously:

[Parallel Competitive Analysis]:
  // Collect data for Product A
  // Collect data for Product B
  // Collect data for Product C

Generate comparative sentiment matrix.

Aspect-Specific Deep Dive

Focus on one feature/aspect across all mentions:

// Filter all content mentioning "multiplayer" or "co-op"
// Analyze sentiment specifically about that aspect
// Generate aspect-focused report

Output Files

All analysis reports are saved to:

• /docs/reddit-sentiment-analysis-[topic]-[date].md - Main report
• /docs/reddit-raw-data-[topic]-[date].json - Raw data (optional)

Integration with Other Skills

This skill works well with:

• competitive-analysis: Use sentiment data for market positioning
• product-roadmap: Prioritize features based on user wishes
• market-research: Combine with other data sources
• trend-analysis: Track sentiment changes over time

Troubleshooting

Issue: Not enough posts found

• Solution: Expand to more subreddits, increase time range

Issue: Sentiment too polarized (all positive or negative)

• Solution: Check subreddit bias (fan subs vs. general subs)

Issue: Missing key aspects in analysis

• Solution: Increase comment depth and limit

Issue: Analysis taking too long

• Solution: Reduce number of posts, focus on top posts only
