ProCodebase Cartographer
A CLI that scans a repository and produces an auto-updating interactive architecture diagram using AI-generated descriptions of each module's responsibility, data flow, and known footguns. It reads git blame to annotate who last touched each component and links to related incident tickets, turning the diagram into a living map for onboarding.
Target Audience
New hires and mid-level developers at Series B+ companies that acquired other startups and now maintain 3ā5 legacy codebases with zero documentation. They currently draw diagrams on whiteboards that are outdated by the next sprint.
Why Now
GitHub shows next-ai-draw-io trending as an AI diagramming tool, and HN had 'Biff.graph: structure your Clojure codebase as a queryable graph'. Dev.to's 'I Deleted 200 Lines of Code I Didn't Write and Learned More' and 'Inherited a Codebase With Zero Comments' reflect the human hunger for understanding unfamiliar code. The intersection of graph-based code querying and AI explanation has arrived.
