Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install imperative-to-fp-ts-refactor

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 finds the imperative parts of a TypeScript codebase and migrates them to fp-ts patterns, with the prerequisites and checks to run. The detailed guide gives the full procedure for end-to-end work.
