Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install fp-ts-error-handling-values

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 rewrites the error handling of TypeScript code with Either and TaskEither, so every failure is visible in the types. It handles side effects and boundaries carefully. You get error handling that is more predictable and easier to test.
