What problem does it solve? Content creators and marketers lack a structured way to track which WeChat Official Account articles are going viral in their sector, and manually collecting reading, sharing, and comment metrics across keywords is slow and unsystematic. ## Core Features & Use Cases - Sector-Based Hot Article Fetching: Query a hot-article data source by sector keywords, merge results, deduplicate, and rank articles by a weighted engagement score. - HTML Analysis Report: Generate a visual report with KPI cards, bar charts, ranked article cards, writing style classification, hot-reason analysis, and reusable title formulas. - Configurable Windows and Sectors: Customize sectors via CLI flags or a JSON config, and adjust the lookback window with --days or --start-date. - Use Case: A content creator covering AI tools runs the script with sectors like 'AI Agent' and 'Claude Code' to get a daily report showing the highest-reading articles, common title patterns, and writing references for their next post. ## Quick Start Ask the AI to fetch the last 7 days of hot WeChat articles for the AI Agent sector and generate the analysis report.
