Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install jest-to-bun-migration

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 removes Jest, adapts imports and mocks, then reruns the suite with bun test. You get a list of APIs that work as is and those that need a change.
