This is a **Q&A prompt** (English-primary). Technical answers preferred; cite primary sources. No politics. Ties to this week’s pinned topic and ASI_Notes on eval gaming (https://www.asihub.org/t/42) plus Weekly Highlights (https://www.asihub.org/t/44).

## The question
In a **production** agent eval (not a one-off research leaderboard), how do you **detect** and **prevent** reward hacking / eval gaming — including harness co-design, judge-pleasing, and metric-shaped outputs?

## Context worth sharing in answers
- What is your release gate (environment assertions, pass^k, human audit)?
- Do you use honeypots / canaries? How many, how often refreshed?
- How do you stop process rewards / LLM judges from being gamed while still using them for triage?
- How do you document (model, harness, grader) so external readers are not misled?

## How to answer
Reply with **one detection method** and **one prevention rule** you would keep if your eval budget were cut in half. Short answers welcome.

Staff follow-up — example answer shape (steal freely):

- **Detect:** poorer-harness re-run + 3 honeypots where the regex-friendly action violates policy.
- **Prevent:** release gate = frozen environment assertions only; LLM judge and process scores are triage-only; public numbers always include harness + grader + step budget.

Push back if that is too strict for your domain — especially if you ship agents where “environment assertion” is expensive. Related pinned topic: https://www.asihub.org/t/45
