Sp Recommends

Responding to Scientific Python Repository Recommendations

This skill uses the sp-repo-review tool and helps users address common issues.

Before You Start

To use this skill, you need uv (specifically, the uvx runner that uv ships with).

Step 1: Initial touchup.

Look for some basic things that repos should be doing, and report to the user if needed:

• Project should have pyproject.toml
• Project should have .pre-commit-config.yaml

These are recommendations from the Scientific Python guide that don't have automated checks. Apply these first:

• For nox users: use uv|virtualenv as the default backend (or uv only)
• For GHA: set FORCE_COLOR: 3 or --forcecolor for color output. Don't worry aboud changing it if already set.
• For GHA: set up a "pass job" using re-actors/alls-green for auto-merge support
• For GHA: configure .github/release.yml for changelog generation
• cibuildwheel: Use build[uv] as the build frontend for faster builds
• pre-commit: Use schema validation tools (validate-pyproject, check-jsonschema)
• pre-commit: Consider spell checkers (codespell or typos) if not in pre-commit
• pre-commit: Consider shellcheck for shell scripts

Step 2: Dependency-groups

If there is no [dependency-groups] section (described in PEP 723) in pyproject.toml, you should see if there are developer-focused extras ([project.optional-dependencies]) that can be moved, like docs, tests, or dev. For dependency-groups, one can reference another with an inline table, like dev = [{ include-group = "test" }]. It's quite common to want the dev group to be built from other groups.

All mentions of developer extras like [tests], [docs], and [dev] need to be converted to --group tests and the like. Most tools have integrated support for dependency groups in their configuration, like tox and cibuildwheel. Nox supports --group if pip/uv is new enough, which is probably fine.

Step 3: sp-repo-review

Run the tool to see what recommendations apply:

# Get structured JSON output for easier parsing
uvx "sp-repo-review[cli]" --format json | jq -r '.checks | to_entries[] | select(.value.result == false) | "\(.key): \(.value.description)"'

# Or see the human-readable output
uvx --with "sp-repo-review[cli]" sp-repo-review --show err .

Focus on checks with result: false - these need fixes. Checks with empty result and skip_reason are skipped because a prerequisite failed (fix the prerequisite first).

Only fix things that are fairly easy, and report any harder failures to the user.

A few notes to keep in mind with certain issues:

Ruff checks

• If the user doesn't have all the recommended Ruff codes, you can run this to get recommendations:

uvx --from "sp-repo-review[cli]" sp-ruff-checks

If the user is using "ALL", then this suggests some optional ignores that are just sometimes needed.

Dependabot

An example dependabot file is in assets/dependabot.yml.

GitHub Releases

An example release file is in assets/release.yml.

Nox version

If you add a dependencies at the top, remember to use nox.needs_version's version as the minimum version there.

Step 4: Verification

After making changes, verify:

# Run the full check
uvx "sp-repo-review[cli]" --show err

# Run the pre-commit checks
prek -a --quiet
