I want to share a new dataset of 331 reward-hackable environments. These are real environments used in Terminal Bench and adjacent benchmarks. I first got interested in this because, as a reviewer of Terminal Bench, I noticed a lot of our tasks were hackable. I also noticed that many contributors to the benchmark do so because it provides credibility when selling environments to labs. Hence, TBench tasks are, in my opinion, held to a higher quality standard than those being used today for RL. No one is spending hours manually reviewing the $1B in tasks being purchased by major labs. As far as I understand, while everyone knows environments are hackable, nobody has released hundreds of "realistic" environments.

Could you build this?
No This is a specialized, curated research benchmark of 331 verified reward-hackable terminal environments requiring deep AI safety and reinforcement learning evaluation expertise.
What it would actually take: Building this requires designing, containerizing (Docker), and thoroughly testing hundreds of real-world command-line task environments, each instrumented with specific verifiers and exploit vectors for reward hacking. It requires deep research expertise in RLHF, agent alignment, and benchmark design, as each environment must balance realistic task completion with detectable reward specification flaws.
