 ### Python Requirements
 
 - **Type hints MANDATORY** - mypy strict mode in `libs/`, all new public functions under utilities MUST be typed
+- **Use `TYPE_CHECKING` for type-only imports** - wrap imports needed solely for type hints in `if TYPE_CHECKING:` to avoid runtime overhead and circular imports
 - **Google-format docstrings REQUIRED** - for all public functions with non-obvious return values OR side effects
 - **No defensive programming** - fail-fast, don't hide bugs with fake defaults (see exceptions below)
 - **ALWAYS use `uv run`** - NEVER execute `python`, `pip`, or `pytest` directly. Use `uv run python`, `uv run pytest`, `uv add` for package installation.
