Code Style Skill

Purpose

Keep code consistent, typed, and easy to maintain.

Standards

• •Use Python 3.13+ idioms.
• •Type public interfaces explicitly.
• •Keep functions small and focused.
• •Use clear domain-oriented names.
• •Add comments only when logic is non-obvious.

Conventions

• •Separate models/config/protocols from runtime services.
• •Use pydantic for input and config validation.
• •Raise explicit domain exceptions.
• •Keep CLI parsing separate from business logic.
• •Keep output schemas explicit and versionable.
• •Prefer enum.StrEnum for single-choice options.
• •Prefer enum.Flag/enum.IntFlag for combinable options, with conversion helpers (str -> flag, flag -> str).
• •Use Google-style docstrings with explicit argument and return types to keep Sphinx generation reliable.

Static Checks

• •Formatting: Ruff formatter.
• •Linting: Ruff.
• •Type checking: Ty.

Commands

• •uv run ruff format .
• •uv run ruff check .
• •uv run ty check src tests
