Step limits, so a wrong call stays small

The most useful guardrail is boring: no single decision may move anything by more than a bounded amount.

By Nimit Solanki · 5 min read

A pricing agent that can set any price is terrifying. A pricing agent that can move a price by at most 8% per cycle is a colleague. Same model, same data. The difference is one number.

Why step limits work

Agents fail in two ways: they are wrong, or they are wrong repeatedly in the same direction. A step limit makes the first harmless and the second visible. If a price drifts 8% a day for four days, a human sees a 30% move in the dashboard and asks why, long before it becomes a catastrophe.

Choosing the step

Step limits for things that are not prices

DomainStep limit
OutreachMax sends per day, per segment, per agent
RefundsMax amount per decision, max total per hour
InventoryMax units reallocated per run
ContentMax pages changed per publish

At estaie, step limits let the pricing agent automate roughly 70% of pricing work. The remaining 30% is exactly the moves that exceeded the limit and went to a person. That split is a feature.

Do this today: add one number to each decision in your inventory: the maximum change per cycle. Put it in config, not in the prompt.
