The evals for my agent skills scored 0% for as long as I had records. Not low. Not noisy. Exactly zero, every skill, every run. And I believed it. For months I thought my skills were bad, because the number said so and the number never wavered. Then one night I actually read the harness. It had fallen back to the wrong auth token. Every call it made came back 401, and it quietly graded each one a failure. The skills never got a chance to fail on their own. I was not measuring them at all. I was reading a broken thermometer. Real weakness is jagged Here is what took me too long to see. When a system is genuinely bad, it scores 40% one week and 60% the next. It passes the easy cases and trips over the hard ones. It has good days. Incompetence has texture, because an incompetent system is still in contact with the world, and the world varies. A flat number has no texture. A flat number means the measurement stopped touching the thing being measured somewhere upstream, and what you are reading is the instrument's resting state. Doctors know this. A heart monitor drawing a perfectly straight line does not mean the patient is calm. Only a broken thermometer writes the same number every time. Key insight: A performance number with no variance is a reading of the instrument, not of the thing being measured. The same bug in three industries I run systems in advertising, in healthcare billing, and in agent operations, and the same shape shows up in all of them. In advertising I found a dashboard figure that had been hardcoded for two years. Nobody questioned it, because it looked right, and it looked right because it never moved. In agent operations, an account-rotation bug in one of my pipelines overwrote every real error with the same generic message, "no active accounts," so for a while every distinct failure in that system looked identical. And in the denial-assessment engine I run for a medical-billing operation, an agreement metric came back at 44.7%, alarmingly low, un

A new feature will indicate when advertisers have used generative AI tools to create or edit their ads, Google says.

Papa Johns is spying on people’s buying activities to predict when they are low on food: The pizza chain recently tapped NBCUniversal, Instacart and the dentsu-owned media agency Carat for help reaching consumers when they’re low on groceries—and thus more likely to be swayed by a mouth-watering ad. The idea is to reach hungry consumers by “knowing what is in their fridge without being too creepy,” said Carrie Drinkwater, chief investment officer at Carat. To achieve that goal, NBCU and Instacart created a custom audience of shoppers who regularly purchase grocery staples on Instacart, such as eggs, milk, meat and produce. Based on that data, Papa Johns can determine which days of the week certain consumers are likely to run out of groceries and serve them an ad on NBCU streaming content accordingly. The brand served custom creatives to consumers based on their food preferences—such as whether they buy meat regularly—with QR codes and calls to action such as, “Light on groceries?” or “Empty fridge?”...
