By guarding type-only imports behind TYPE_CHECKING, you eliminate their runtime overhead (important for large libraries like pandas), reduce circular import issues, and organize imports more cleanly. The plugin works by classifying imports as application, third-party, or built-in, then checking whether they're actually used at runtime or only in annotations.\n\nIt offers two strategies for handling forward references: TC100-range codes use postponed evaluation (from __future__ import annotations), while TC200-range codes use string literals. You configure which strategy suits your codebase and Python version target. The plugin includes special handling for frameworks like Pydantic and FastAPI, where class annotations are evaluated at runtime, and can be tuned with strict mode, exemptions, and custom typing module paths.","worth_installing":"Yes. This is a focused, low-friction plugin that solves a real problem\u2014unnecessary runtime import overhead and circular dependencies\u2014with active maintenance, no security issues, and permissive licensing.
