Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install prompt-regression-testing

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent records model settings, required checks and missing results, then finds regressions case by case: schema, factuality, refusals or tool selection. It also flags the limits of the automated judge.
