I think we should aim to include:

• PY005: - Has tests folder
• PP003: - Does not list wheel as a build-dep
• PP301: - Has pytest in project
• PP309: - Filter warnings specified
• PC110: - Uses black or ruff-format
• PC140: - Uses a type checker
• PC160: - Uses a spell checker
• PC170: - Uses PyGrep hooks (only needed if rST present)
• PC190: - Uses Ruff
• PC901: - Custom pre-commit CI message
• RF001: - Has Ruff config

With these being nice to haves:

• PP304: - Sets the log level in pytest
• PP305: - Specifies xfail_strict
• PP306: - Specifies strict config
• PP307: - Specifies strict markers
• GH212: - Require GHA update grouping
• PC180: - Uses a markdown formatter
• MY100: - Uses MyPy (pyproject config)

@bjlittle that sound about right?
