# atelier-core Foundational effects and utilities for effect-based applications, built on [Effectful](https://github.com/haskell-effectful/effectful). Part of the **atelier** toolkit. ## Overview `atelier-core` provides a set of composable Effectful effects and supporting types for building structured, observable applications. It also wraps a number of `IO`-based primitives (environment, clock, file system, console, POSIX) as effects so they can be interpreted and tested explicitly: `Atelier.Effects.Env`, `Atelier.Effects.Clock`, `Atelier.Effects.FileSystem`, `Atelier.Effects.Console`, `Atelier.Effects.Posix.*`, and more. ## License MIT — see [LICENSE](LICENSE).
