## What refactoring-guru does, in the publisher's words

A dedicated Pi agent extension derived from the complete upstream Refactoring.Guru rules folder.

The command starts a new, named session instead of changing the current assistant. The replacement session receives a refactoring-specific system prompt, repository instructions, a live Git/project snapshot, and a curated coding tool set.

Use --refactoring-guru only when the current session should start directly in this role.

- refactoring_impact categorizes lexical symbol hits across the target, production dependents, tests, and public contract surfaces.
- refactoring_checkpoint records the smell, treatment, scope, stop condition, dirty baseline, and no-shell verification commands; its verification result gates behavior-preservation claims.
- refactoring_catalog searches the full upstream treatment catalog after a smell is diagnosed.
