baseline-py

Structural linter and config scaffolder for Python: atomic files, placement, size caps, no inline SQL. Brings the same discipline as @busirocket/eslint-config and cargo-baseline to Python projects.

Design spec: docs/superpowers/specs/2026-08-31-python-baseline-design.md.

Install

uv add --dev busirocket-baseline-py

Usage

baseline-py init [--check|--apply|--force]  # scaffold ruff, mypy, deptry,
                                            # pytest, coverage and CI config
baseline-py check [PATH...]                 # run the structural rules
baseline-py gate                            # run the whole quality chain
baseline-py baseline create|update|check    # track migration debt

init never overwrites: it merges into existing configuration, or reports a conflict. check never writes. gate fails when a required tool is absent rather than skipping it.

Rules

Code	Rule	Enforces
`BPY000`	`parse-error`	A file that fails to parse is a finding, never a silent skip.
`BPY001`	`one-primary-unit`	Exactly one primary declaration per ordinary module.
`BPY002`	`file-matches-unit`	File name is the snake_case of its primary declaration.
`BPY003`	`no-grab-bag-names`	No `utils`, `helpers`, `misc` or `common` in any path segment.
`BPY004`	`max-file-lines`	Code-line cap per file; tests get their own, looser cap.
`BPY005`	`barrel-only-init`	`__init__.py` holds imports, `__all__` and nothing else.
`BPY006`	`no-inline-sql`	SQL lives in resource files, not in string literals.

Exit codes

Code	Meaning
0	All blocking checks passed.
1	Policy findings.
2	Invalid usage or invalid configuration.
3	Infrastructure failure: a required tool is missing or unusable.
