Writing code with an assistant is fast, and the speed is real. What tends to be left behind is the unglamorous part: a key committed while wiring up a service, a dependency pinned months ago and never revisited, a permission check that was described in a prompt but never written.
None of that is a failure of the tools. It is what happens when the reviewing half of the work does not keep pace with the writing half.
Monterva runs deterministic scanners over a repository and reports potential issues with the evidence behind each one, the confidence attached to it, a recommended remediation, and a plain statement of what was not covered. More on how that works is on how it works.
