Harbor + Docker Sandboxes: microVM agent evals for Claude Code, Codex, Cursor
As of Oct 14, Harbor can run every eval task in Docker Sandboxes—microVMs that isolate agents like Claude Code, Codex, and Cursor with configurable network policies for fair, reproducible benchmarks. Nightly harbor[sbx] is available now; stable lands Oct 23, with the same tasks runnable locally or on Docker Cloud Sandboxes.
