# oz0 compare

> Usage and flags for oz0 compare.

For: Operators and developers looking up a command.

A comparison of a changed agent runs the agent as installed (the baseline) and one change (the variant: another revision of its plugin, your studio draft of it, the agent without one of its skills, or the agent with one of its delegates folded in: the delegate's instructions as a skill, its tools and skills beside the agent's, and no delegation to it) on the same cases, several runs of each, as shadow runs: writes answer from a stub and no approval is asked for, so nothing acts on the world.

The verdict is better, same or worse on the paired pass rate, with each failure split by the rubric's criterion where a judge named one, or undecided when there are too few cases or runs to tell. Same means not worse than the baseline by more than the margin. It states no cost or saving: measure what a setting saves with compare-savings. A comparison spends the tenant's money and needs a budget.

## Usage

```bash
oz0 compare [command]
