Visualize Security Responsibility Topology from Git History Using security-ownership-map

# Security-Ownership-Map: An OpenAI Curated Agent Skill Security-Ownership-Map is an OpenAI curated Agent Skill that constructs human-file bipartite graphs and covariation clustering based on Git history, calculates the Bus Factor of sensitive code, and supports output in CSV/JSON formats (with optional Neo4j/Gephi exports). This article introduces its positioning, installation and activation, usage of `run_ownership_map` and `query_ownership`, sensitive code rules and applicable boundaries, which is suitable for enterprise security teams to conduct inventory of ownership drift and orphaned sensitive code.
