just-fmt

Check (or apply) just’s built-in formatter across every justfile and .just module in a directory tree. just --fmt is still gated behind --unstable in current just, so JUST_UNSTABLE is set for you. Vendored modules (.just/vendor/), node_modules, and .venv are skipped. Run actions/checkout first.

Inputs

Input	Required	Default	Description
working-directory	no	.	Directory to scan for justfiles.
mode	no	check	“check” (fail if any file is unformatted) or “write” (format in place).
