pylines

Python backend development guidelines based on the pylines project (community-of-python/pylines). Use this skill whenever writing, reviewing, or refactoring Python code — especially backend code with FastAPI, Litestar, SQLAlchemy, or similar stack. Trigger on any Python code generation, code review, architecture discussion, REST API design, test writing, or when the user mentions "pylines", "code style", "наши гайдлайны", "python guidelines", or asks to follow team conventions. Also trigger when writing pyproject.toml configs for ruff/mypy, designing class hierarchies, discussing SOLID in Python, or structuring a Python project.
