farol Open-Source CLI and GitHub Action: Assessing PR Merge Risk After AI Review

farol is an MIT-licensed open-source CLI and GitHub Action that, after AI code review, provides a merge risk conclusion, a 0–100 risk score, and the highest-risk files, and lists the pages, APIs, tasks, and scripts touched by the changed code. It performs static analysis based on the TypeScript type checker, go/types, and Python ast, without executing or externally transmitting code, and can be run via npx @winninjs/farol or winnin/farol/action; it only comments and does not block merges. The author states that across 662 historical commits in four repositories, none of the 56 commits in the fast track tier had issues, and the risk score AUC was 0.72–0.83.
