SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Developers on fresh machines often cannot run the project's justfile recipes because just is missing, or because winget installs it into a folder that is not on PATH. This Skill installs just on Windows, macOS, or Linux, repairs the PATH gap, and proves the repo's recipes actually list and run. ## Core Features & Use Cases - Cross-platform installation: Installs just via winget, scoop, Homebrew, or the official curl installer depending on the operating system. - Windows PATH repair: Copies just.exe from the versioned winget package folder into the WinGet Links directory so new terminals can find it. - Verification and smoke test: Runs just from the repo root to list recipes and executes the cheapest safe recipe to confirm the setup works. - Use Case: A developer clones a project, types just, and gets "command not found". This Skill installs the binary, fixes PATH, and confirms just build runs before handing off. ## Quick Start Ask the assistant to set up just on this machine and verify the project's recipes run.

Frequently Asked Questions about setup-just

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I install just on Windows?▼

Install just on Windows with winget install Casey.Just or scoop install just. After a winget install, copy just.exe from the versioned Packages folder into the WinGet Links folder so it lands on PATH, then reopen the terminal.

Why is just not recognized after installing with winget?▼

winget installs just.exe into a versioned package folder that is not on PATH. Copy the binary into %LOCALAPPDATA%\Microsoft\WinGet\Links, then close and reopen the terminal because running shells cache PATH at process start.

How do I fix the error 'No justfile found' when running just?▼

The error means you are not in the repository root where the justfile lives. Change directory to the folder containing the justfile and run just again to list the project's recipes.

Can I install just with npm?▼

No, just is a standalone binary, not a Node package, so npm installation is an anti-pattern. Use winget or scoop on Windows, Homebrew on macOS, or the official curl installer on Linux.

Why does a just recipe fail with '&&' is not a valid statement separator?▼

Windows PowerShell 5.1 does not support the && operator used in some recipes. Replace && with a semicolon or split the command into separate recipe lines so PowerShell can parse it.
