Restructure code while preserving behavior. Use for extraction, consolidation, ownership moves, or cleanup where verification must bracket structural edits.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Safe refactor Define behavior-preservation boundary and establish verification before structural edits. - Keep feature changes outside refactor. - Move one ownership boundary at a time. - Preserve public interfaces, failure behavior, ordering, and compatibility unless explicitly scoped. - Keep intermediate states buildable and testable. - Avoid dependency or configuration growth without correctness need. Run same proof after change. Stop when behavior matches and requested structure is achieved.

How to install
mdr add juliusbrussee/caveman/safe-refactor@sha256:cd52867aba26aafbThe line at the top of this page pins the label git:20260811.82864c8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
