OUSPG-PRISM

Platform for Repository Intelligence and Software Metrics

PRISM is a suite of tools for studying the impact of AI inflection points on measurable outcomes. The primary application is open-source software development — tracking ~1,380 GitHub repositories across six analytical domains and five temporal cohorts — but the analysis tools are data-agnostic and can be applied to any time-series data (financial markets, job postings, industry trends, etc.).

Tools

Tool	Description
prism-collect	Data collection engine — mirrors PR metadata and repository snapshots from the GitHub GraphQL API into a local PostgreSQL database
prism-analyze	Statistical analysis engine — detects whether AI inflection points caused structural breaks in any time-series data (ITS, DiD, Bai-Perron)
prism-dashboard	(coming soon) Visualization and reporting interface
