Scans a codebase for covert, deceptive, or data-stealing behavior with Jev, then reports suspicious files and line ranges before the user runs it.

CLI codebase scanner that sends source, config, build, and CI files to TypeSafe Jev to flag deceptive or data-stealing behavior with file/line pointers. A clean report is not proof a project is safe.

have jev check if code is malicious before you run it, its cheap enough to scan entire codebases can also be used as a first line defense against malicious prs

Allow, flag or escalate a message, tool call or action.

Where it fits
