Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install typescript-typed-idioms

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 TypeScript rules to .ts, .tsx, .js and tsconfig.json files: discriminated unions, validation of external data with Zod and optional type-fest utilities. For React components, it also relies on the React skill.
