Score: 5.5/10 (Innovation: 6, Technical: 5, Documentation: 6, Utility: 5)

Jeff is a read-only Go CLI that performs semantic code review by checking files against a set of 20 rules (e.g., unclear responsibility, hidden side effects, poor error context) using the Jev engine from TypeSafe. It stands out by focusing on semantic, design-level issues rather than syntax or style, and offers both text and JSON output for CI integration.

Target audience: backend developers, devops engineers, code reviewers
