just — Command Runner

Use just to make project commands discoverable, reproducible, and easy for humans, agents, and CI to run. It is not a build system; recipes run when invoked and do not track file timestamps like Make.

Workflow

1. Inspect existing project commands first: justfile, package.json, pyproject.toml, Makefile, CI config, scripts, and README snippets.
2. Add or update recipes around commands the project already uses; avoid inventing a new toolchain.
3. Keep public recipes documented and stable because CI and agents will depend on them.
4. Run just --fmt when supported, then run just --list and the changed recipes or just ci when safe.
5. Report the recipe names changed and which recipe CI should call.
