Rules

REJECT if:

• Missing type hints on public functions or methods
• Bare except: without a specific exception type
• print() used in production code (use logging instead)
• Mutable default arguments (e.g., def f(x=[]):)

REQUIRE:

• from __future__ import annotations in all modules
• Type hints on all public functions and class attributes
• Pydantic v2 for data validation models

PREFER:

• Early returns over deeply nested conditionals
• pathlib.Path over os.path for filesystem operations
• Dataclasses or Pydantic over raw dicts for structured data
