Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install port-code-tests-first

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 ports tests first, then the code, binding each function to its tests through a coverage map. It uses jscpd --compare to measure what is left to port and check parity between two implementations. You get a port that is tracked and verifiable.
