Security Ownership Map

Overview

Build a bipartite graph of people and files from git history, then compute ownership risk and export graph artifacts for Neo4j/Gephi. Also build a file co-change graph (Jaccard similarity on shared commits) to cluster files by how they move together while ignoring large, noisy commits.

Requirements

• Python 3
• networkx (required; community detection is enabled by default)

No separate install step: every command below runs through uv run --with networkx, which provisions networkx for that run.

Workflow

All script paths below are relative to this skill's folder (the directory containing SKILL.md); run them from there or prefix with that path.
