sp-repo-review 2026.3.2

sp-repo-review provides checks based on the Scientific-Python Development Guide at scientific-python/cookie for repo-review.

This tool can check the style of a repository. Use like this:

uvx sp-repo-review[cli] <path to repository>

This will produce a list of results - green checkmarks mean this rule is followed, red x’s mean the rule is not. A yellow warning sign means that the check was skipped because a previous required check failed. Some checks will fail, that’s okay - the goal is bring all possible issues to your attention, not to force compliance with arbitrary checks. Eventually there might be a way to mark checks as ignored.

For example, GH101 expects all your action files to have a nice name: field. If you are happy with the file-based names you see in CI, you should feel free to simply ignore this check (you can specify ignored checks in pyproject.toml or by passing args to repo-review, see the repo-review docs).

All checks are mentioned at least in some way in the Scientific-Python Development Guide. You should read that first - if you are not attempting to follow them, some of the checks might not work. For example, the guidelines specify pytest configuration be placed in pyproject.toml. If you place it somewhere else, then all the pytest checks will be skipped.

This was originally developed for Scikit-HEP before moving to Scientific Python.

Extras

• cli: Dependencies to run the CLI (not needed for programmatic access, like on Web Assembly)
• pyproject: Include validate pyproject with schema store.
• all: All extras

Helper utility

There's also a script, accessible as sp-ruff-checks, that will compare your ruff checks to the known values. It's a little more elegant on the command line than the Ruff family description, which will only print out a basic list.

Other ways to use

You can also use GitHub Actions:

- uses: scientific-python/cookie@<version>

Or pre-commit:

- repo: https://github.com/scientific-python/cookie
  rev: <version>
  hooks:
    - id: sp-repo-review

If you use additional_dependencies to add more plugins, like validate-pyproject, you should also include "repo-review[cli]" to ensure the CLI requirements are included.
