Cline's code review agent is recorded as a tooling-loop signal. The useful observation is that review is being packaged as a repeatable agent workflow with source inspection, critique, and output generation rather than as a single chat prompt.
For New Runtime, code review is one of the cleanest places to watch agent reliability. The artifacts are concrete, the failure modes can be inspected, and the workflow naturally demands traceability. The next signal to watch is whether Cline-style review agents produce auditable evidence of what they inspected and why they changed a recommendation.
