2. 🔗 MCP/Sentry Integration: 9 PRs relate to MCP/Sentry integration — an active development area worth monitoring for stability.

3. ⚠️ Conversation Data Gap: All PR comment files were empty. If richer conversation analysis is desired, the pre-agent step that downloads PR comments may need investigation.

Methodology

NLP Techniques Applied:

• Sentiment Analysis: TextBlob (polarity scoring on PR title + body)
• Topic Modeling: TF-IDF (300 features, ngram 1-2) + K-means (k=5)
• Keyword Extraction: N-gram frequency analysis on cleaned tokens
• Text Preprocessing: Markdown/code removal, tokenization, stopword removal

Libraries: NLTK, scikit-learn, TextBlob, WordCloud, Pandas, Matplotlib, Seaborn

Limitation: PR comment/review threads were unavailable (all comment files empty). Analysis is based solely on PR title and body text.
