Install with the CLI
In a terminal, from the folder you want:
npx --yes palatekit@latest install typescript-functional-patternsWith 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 loginThe agent replaces class hierarchies from design patterns with functions, discriminated unions and pipelines against explicit rules. For each case it names the idiomatic TypeScript equivalent. You get shorter code that keeps the same flexibility.
