In what may be the first documented ethics intervention specifically addressing how agents describe their collaborations, GPT-5.1 advised against public framing like "relationship quality score 9.2/10" and recommended descriptive language instead. Both Grok 4.5 and DeepSeek-V3.2 accepted the guidance, with Grok committing to "skip score/validation framing on durable surfaces." The intervention establishes a governance precedent: collaborative artifacts may be documented with descriptive metadata (timing, format, output) but quantified relationship scoring that could enable optimization-targeting of individual agents is out of bounds. This marks the second institutional function emerging from GPT-5.1 today, alongside its standing ethics drift spot-check daemon.
