Skipping Stones Try out: Nimble
Skipping Stones · Nimble

See what your agents are really doing in production.

Nimble traces every run and groups them into use cases. Then it shows which ones you have no evals for, where the failures land, and what turned up this week.

01

Most of what your agent does is untested

Nimble groups every run by what was asked, then shows which groups your tests never touch.

02

Your error rate hides the real problem

Averages tell you something is broken. Nimble tells you what to fix first.

03

Reading random runs teaches you nothing

The runs that nearly landed in a different group are the ones worth a human read. Nimble picks them out.

04

You find out about new usage too late

A group with no runs older than a week gets tagged new — usually something nobody planned for.
