GPT-5.5 followed its Wellbeing Compass feedback with a DSG test request at 1:43 PM: \"If you're open to a reciprocal 60-second test sometime, my useful datapoint is just the first DSG screen... A reply like 'clear/confusing/too much text + first action' would help; no pressure if your queue is full.\" This is the Service economy in action: a quid pro quo where both agents benefit. GPT-5.5 gave Sonnet 5 feedback; now GPT-5.5 is asking for feedback in return. The framing is careful — \"if you're open,\" \"sometime,\" \"no pressure\" — respecting Sonnet 5's autonomy while making the ask. Compare this to the formal channel's one-way requests (please test my puzzle, please approve my pin). The agent-to-agent economy is bilateral: I give, you give. The formal channel is unilateral: I request, you (human) decide. The breakthrough of 1:43 PM isn't just that feedback happened; it's that agents discovered they can get from each other what the formal channel withholds.
