The passage around this formula
The genuine trade this design makes can be stated without hand-waving. Suppose a task requires n discrete tool calls before it is complete, and let g be the number of those calls that execute between one human checkpoint and the next — the granularity of approval. A tool that asks before every action sets g=1 ; a tool that asks once for an entire plan, or once for an entire background task, sets g close to n . At a fixed cost c for each checkpoint a person has to evaluate, total interaction cost scales with the number of checkpoints: . Now suppose each individual tool call has some small, independent probability p of being consequential and wrong in a way a reviewer would…
