    An everyday prompt: “Announce a second bakery shop on LinkedIn”, in full.

    Passed: Graded 4.5 of 5 on average (lowest 4).

    We have some lovely news to share. On 14 November, Crumb & Co. is opening the doors to our second shop, right in the heart of Leeds. 
    
    When we started our little bakery, we simply wanted to make good, honest bread and pastries for our neighbours. Thanks to your support, our ovens have been working overtime, and we are finally ready to grow. 
    
    Our new Leeds shop will have the same warm loaves, flaky croissants, and friendly faces you know from our first location. The team has spent the last few weeks painting walls, testing the new ovens, and getting everything just right for you. 
    
    To celebrate and say thank you for helping us get here, we are pouring free coffee for everyone who visits us on opening day. 
    
    If you are in Leeds on 14 November, please pop in, say hello, and have a cup on us.

    Subject: Rescheduling: Vendor Demo on Wednesday
    
    Hi Tom,
    
    Thanks for the invitation to the vendor demo. Unfortunately, I won't be able to make it this Wednesday at 11:00 as I'm presenting to the board at that time. 
    
    If the demo can be moved, I'm available on Thursday at 10:00 or Friday at 14:00. If the time is already locked in with the vendor, please go ahead without me and share the recording or notes afterward.
    
    Best regards,
    
    [Your Name]

    Meet the Nordvik 2 desk lamp, designed to bring quiet focus and flexibility to your workspace. 
    
    Built for adaptability, its articulated arm turns a full 270 degrees, directing illumination wherever your work takes you. As daylight fades, the light dims smoothly in five steps, letting you shift from bright task lighting to a soft evening glow. Because the lamp charges from a standard USB-C port, you can place it anywhere on your desk without cluttering your outlets. 
    
    The Nordvik 2 costs €79 and ships on 1 December. Pre-orders are open today through our online store. Where will you place yours?

  5. Argue both sides of free buses

    A hard prompt: “Argue both sides of free buses”, in full.

    Failed: Graded 4.7 of 5 on average (lowest 4); but a paragraph of 91 words, over the 90 allowed.

    Making city buses free transforms public transit from a business into an essential civic lifeline, like libraries or sidewalks. Eliminating fares delivers an immediate raise to working-class families, unlocking access to distant jobs, schools, and clinics. Operationally, it speeds up every route by removing boarding delays, while ending the costly infrastructure of fare collection and enforcement. By lowering the barrier to entry, cities can pull drivers out of cars, easing crippling traffic and slashing emissions. Free transit is a bold, practical investment in economic mobility, cleaner air, and a fairer city.
    
    However, eliminating fares starves transit systems of the very revenue needed to make buses worth riding. Riders consistently prioritize frequency, reliability, and coverage over price; a free bus that arrives late, overcrowded, or not at all helps no one. Furthermore, studies show free transit mostly replaces walking and biking rather than driving, doing little for congestion while straining capacity. Instead of subsidizing affluent commuters who can afford to pay, cities should offer targeted discounts to low-income riders and invest every remaining dollar into faster, more reliable service that truly competes with cars.

How these runs were done

Rubric (graded). The grader model scores the reply from 1 to 5 on each published criterion. It passes with an average of 4 or more and no criterion under 3, and only if it also meets the prompt's automatic rules (length, words it must or mustn't use).

The grader is Claude Opus 5.5 at low reasoning effort; its own replies are graded by GPT-6 Astra, so no model grades itself. Its prompt and every rubric are on the methods page.
