Could you build this?

No An evaluation and testing harness built specifically for Recursive Self-Improvement (RSI) requires novel frontier AI safety research and automated agentic execution environments.

What it would actually take: The architecture requires sandboxed Linux runtime orchestration (Docker/Firecracker microVMs), complex agent introspection hooks, verifiable task environments (e.g., SWE-bench, theorem provers), and automated code mutation pipelines. The technical crux is ensuring formal safety boundaries and accurate verification of non-trivial autonomous code improvements without infinite looping or sandbox escapes. It demands specialized AI alignment and frontier systems researchers.
