Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install typescript-refactoring-patterns

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 reviews or refactors TypeScript and TSX against 47 rules, current to TypeScript 6.0 and React 19. It removes unsafe casts, prefers discriminated unions and types components and hooks. You get safer and more readable code.
