Repo-Archi-Graph

Repo-Archi-Graph is a production-ready fullstack AI application that revolutionizes how developers understand and manage codebase complexity. By leveraging IBM Bob's advanced contextual reasoning capabilities, it transforms static repositories into interactive architectural intelligence networks. The platform performs deep analysis across four critical dimensions: First, it computes blast radius scores (1-10 scale) for every file, quantifying the system-wide impact of potential modifications. Second, it conducts comprehensive technical debt audits, identifying SOLID principle violations, security vulnerabilities, and maintainability issues with brutally honest AI critiques. Third, it maps semantic dependencies beyond simple imports, understanding architectural roles and relationships. Fourth, it generates actionable recommendations for refactoring and risk mitigation. Built with a decoupled architecture (Python FastAPI backend + Vis.js interactive frontend), the solution showcases IBM Bob acting as a Virtual CTO—analyzing coupling metrics, evaluating cascading failure risks, and providing CTO-level insights that enable proactive engineering decisions. Unlike traditional static analysis tools that provide surface-level metrics, IBM Bob reasons about architecture contextually, delivering intelligence that mirrors senior engineering expertise. The interactive visualization allows developers to click any node and instantly view AI-generated summaries, risk scores, lines of code, and detailed debt analysis—transforming architectural understanding from abstract concepts into tangible, actionable data.
