Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install ai-code-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 writes Vitest tests that run through the sandbox mode of your Next.js API, without a real database, and wires them into the bug check. You get protection against a bug coming back, and a check the same model cannot skip.
