Instruments
The publication’s working rule is instruments over theory. These are the runnable ones — free, no login, each built alongside an essay. Every instrument runs in your browser and reads only what you give it.

- The Marathon Calculator Per-step reliability compounds over a long agent run. See the finish-rate gap and the cost per finished task.
- The Metric Validity Audit Pick your metric. Get a bespoke audit: how it lies, the blind spot you missed, and what to do.
