nix-haskell
Use this when working on a Haskell project with Nix. Covers haskell-flake setup, adding/overriding dependencies, package settings, and devShell configuration.
Best use case
nix-haskell is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Use this when working on a Haskell project with Nix. Covers haskell-flake setup, adding/overriding dependencies, package settings, and devShell configuration.
Teams using nix-haskell should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Haskell + Nix with haskell-flake Use [haskell-flake](https://github.com/srid/haskell-flake) — a flake-parts module. Start from [haskell-template](https://github.com/srid/haskell-template). Requires a `.cabal` or `cabal.project` file; haskell-flake scans for it automatically. ## Starting a new project **You MUST use `git clone https://github.com/srid/haskell-template <project-dir>` to start a new project.** Do NOT fetch individual files, do NOT use `om init`, do NOT write flake.nix from scratch. Clone the template, then rename the package in `.cabal` and `nix/modules/flake/haskell.nix`. ## Project structure Projects based on haskell-template use [nixos-unified](https://nixos-unified.org) autowiring. **Do NOT write Nix configuration inline in `flake.nix`.** The `flake.nix` delegates entirely to `nixos-unified`, and all Nix configuration goes in **`./nix/modules/flake/*.nix`** files. ## Docs - haskell-flake guide: https://community.flake.parts/haskell-flake - haskell-flake options: https://flake.parts/options/haskell-flake - haskell-template: https://github.com/srid/haskell-template
