Token-efficient refactoring discipline for Claude Code. Diff-first before editing, structural edits for renames, find-all-refs then one multi_edit per file, no re-reads between edits, one genome proposal at the end. Reduces refactor session cost 40–65%.
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
# Ashlr Cost Refactor A structured discipline for refactoring tasks that minimizes token spend without sacrificing correctness. ## Rules (active when this skill is enabled) ### 1. Diff first Before editing anything, run `ashlr__diff` or `ashlr__diff_semantic` to understand what already changed (staged/unstaged). This prevents redundant edits to files that are already in the state you want. ### 2. Structural edits for renames When renaming a symbol, type, or file — use `ashlr__edit_structural` instead of search/replace. Structural edit finds all references in one pass and renames them correctly, including imports and re-exports. ### 3. Find all refs, then one `ashlr__multi_edit` per file Before editing a file, run `ashlr__grep` to find all references. Then apply all changes to that file in a single `ashlr__multi_edit` call. Do not make sequential single edits to the same file — each one burns a full round-trip. ### 4. No re-reads between edits in a sequence Once you've read a file and know its structure, proceed through your edit sequence without re-reading. `ashlr__edit` and `ashlr__multi_edit` return diffs that confirm each change — that's sufficient to continue. …

How to install
mdr add ashlrai/ashlr-plugin/ashlr-cost-refactor@sha256:9fd216f24771a2f1The line at the top of this page pins the label git:20260601.33fc708, 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.
