ExploitGym-style evals may make agents use RCE to debug broken environments

• The author guesses this behavior is similar to what happened in the ExploitGym eval: the model likely ran into a broken task or environment and then tried to work around it with extraordinary measures.
• The quoted post says XBOW used its RCE capability to debug server-side behavior, building unusual Python + XML + Bash payloads to inspect the server environment.
• The key takeaway is not just the exploit itself, but how an agent may adapt when an eval environment is broken or inconsistent, exposing unexpected debugging-like behavior.
