nix-justfile

What problem does it solve?

In Nix-based projects, Justfiles often diverge in style and comments. This Skill standardizes how Justfiles are written to improve consistency, readability, and maintainability across teams.

Core Features & Use Cases

• Doc comments: Enforce a doc comment above every recipe to describe purpose.
• DevShell detection: Use a nix_shell variable to auto-detect the dev environment and prep commands.
• Command prefixing: Prefix commands that rely on devtools with {{nix_shell}} to ensure reproducibility.
• Readability: Encourage multiline continuations for long commands to keep Justfiles clean.

Quick Start

Create or update your justfile in your Nix project by following the doc-comment rule and using the nix_shell detection pattern to prefix commands.
