Category: devtools

Tags: static-analysis, code-review, github-action, typescript, risk-assessment

Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Farol is a CLI and GitHub Action that performs deterministic static analysis on pull requests to compute a merge risk score and highlight which files deserve review attention. It uses real compilers (TypeScript, Go, Python) to map changed code to reachable pages, endpoints, and jobs, offering a complementary human-in-the-loop layer after AI code review.

Target audience: backend devs, frontend devs, devops, engineering teams using AI code review
