Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install fp-ts-either-reference

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 relies on a reference card for fp-ts's Either type: creating, transforming and extracting values, handling validation and converting code that throws exceptions. It replaces a long tutorial with patterns you can use directly.
