axm-anvil

Move, rename and extract top-level Python symbols with libcst transformations. Anvil uses axm-ast for code analysis and axm-edit for batched writes; it changes files.

Your goal	Start here
Try a complete move on disposable files	Getting started
Choose move, rename or extract	Operation contracts
Use the tool from an agent	MCP and generic AXM CLI
Apply a real refactor	Review workflow
Understand rollback and rewriting limits	Guarantees and limits
Integrate from Python	Python API

Install with uv add axm-anvil (Python 3.12+). The dedicated CLI provides axm-anvil move; the generic AXM dispatcher exposes anvil_move, anvil_rename and anvil_extract when installed in its environment.

Preview first. A successful result can contain warnings, and a parseable transformation is not proof of unchanged behavior. Move/extract run optional Ruff cleanup after batched writes; exact formatting and end-to-end transactional rollback are not guaranteed.
