# Python Rules

## Apply Order

1. start with `rules/common/`
2. layer `rules/python/` for Pythonic typing, packaging, and test strategy guidance
3. consult `knowledge-bases/structured/python/docs/` and `knowledge-bases/structured/python/examples/` before deviating from the promoted patterns

## Focus Areas

- typing, module boundaries, and dependency management
- test strategy, validation, and framework-safe changes
- automation, API, and data-workflow constraints when they affect design
