SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Build a bipartite graph of people and files from git history to surface ownership risk and enable governance and audit workflows.

Core Features & Use Cases

  • Build ownership maps from git history and export graph artifacts compatible with Neo4j/Gephi.
  • Generate a co-change graph to cluster files by shared commits while ignoring noise, enabling risk analysis.
  • Visualize maintainership and hotspots to guide security reviews and code ownership decisions.

Quick Start

Run the ownership map workflow from the repository root to generate the ownership and co-change graphs and export visualization-ready artifacts.

Frequently Asked Questions about security-ownership-map

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I map git ownership to identify code risk clusters?▼

Mapping git ownership involves building a bipartite graph of people and files from commit history to surface ownership risk clusters. The workflow exports visualization-ready artifacts compatible with Neo4j and Gephi for further analysis.

What is a co-change graph and how does it help with risk analysis?▼

A co-change graph clusters files by shared commits while ignoring noise to enable risk analysis. It groups files that frequently change together in git history to reveal hidden dependencies and ownership hotspots.

Can I export git ownership data to Neo4j or Gephi for visualization?▼

Yes, you can export git ownership data to Neo4j or Gephi. The workflow generates graph artifacts specifically designed to be visualization-ready, allowing you to import the bipartite people-file graph directly into these network visualization tools.

Do I need Python 3 to build an ownership map from git history?▼

Yes, you need Python 3 and the associated graph tooling scripts to build an ownership map from git history. These scripts generate the bipartite graphs, queries, and reports required for the analysis.

When should I use a bipartite graph for code ownership analysis?▼

Use a bipartite graph for code ownership analysis when you need to understand who touches which files in a repository for governance and audit workflows. It effectively surfaces maintainership hotspots and ownership risk clusters.
