Typescript

Gives Claude solid TypeScript foundations: strict mode, explicit typing over inference, modern tooling with Vitest and Vite instead of older options. Pushes composition over inheritance, dependency injection, and keeping types close to usage. The linting and formatting setup is opinionated but reasonable (Prettier at 120 characters, ESLint with TypeScript plugin). Worth noting it suggests Astro for content sites and pnpm for everything, which might not match your stack. The testing guidance is lightweight but covers the basics. If you're setting standards for a team or want Claude to write TypeScript that doesn't fight your build pipeline, this handles the common decisions.
