This one's for teams going deep on Effect-TS, the functional programming library that turns TypeScript into something closer to Scala or Haskell. It comes loaded with research patterns that tell Claude to actually dig through the Effect source code at ~/.effect before suggesting solutions, which is smart because Effect has five ways to do everything and the docs don't always clarify which is idiomatic. The skill emphasizes codebase pattern discovery first, so you get consistency with your existing code, then falls back to canonical patterns. Heavy focus on typed errors, dependency injection with Services and Layers, and avoiding the classic footguns like try-catch blocks inside Effect.gen (they don't work the way you'd expect). Worth it if Effect is central to your stack.
