SKILL.md

Overview Effect-TS provides a powerful functional framework, but common imperative habits can bypass its safety guarantees. This skill identifies and fixes patterns that lead to resource leaks, process crashes, and unhandled errors.

| Anti-Pattern | Bad Code | Good Code | Why |

| Run Outside Boundary | await Effect.runPromise(fx) mid-function | yield fx (compose) | Bypasses error channel & tracing. | | Missing yield | const user = yield fetchUser() | const user = yield fetchUser() | Yields the Effect object, not the result. |
