The system uses a hybrid scoring approach combining weighted metrics (activity, maintenance, community, documentation) with LLM-based adjustments to account for context like feature-complete projects. Key features include PR metrics analysis, contributor retention visualization, intelligent issue analysis with difficulty scoring, activity pattern detection for spam, and file-issue mapping. The author shares technical implementation details, bug fixes (cache security vulnerability, React hydration mismatch), and lessons learned about focusing on real problems over engineering challenges. ## Full article daily.dev links to this article rather than hosting it.
