Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install typescript-advanced-type-patterns-2

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 applies advanced patterns: branded types to tell identifiers apart, discriminated unions with type narrowing, conditional types with infer and Zod schema inference. You get code examples and anti-patterns to avoid.
