Use when proving that a frontend refactoring preserved existing behavior, selecting an appropriate safety net, validating each structural step, or assigning a PASS, PARTIAL, or NOT PROVEN preservation verdict.
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
# Skill: Refactoring Validation ## Purpose Define the observable contract and the smallest credible evidence needed to prove that structural edits preserved existing frontend behavior. ## Procedure 1. Record the relevant behavior contract before substantial edits. 2. Classify safety-net coverage as A, B, or C. 3. Run and record the pre-change baseline. 4. Match verification to the current refactoring risk and affected boundary. 5. After every structural step, run the narrowest sufficient check immediately. 6. If a newly introduced failure appears, revert that step before broader repair. 7. At the end, run the broad gates justified by the affected surface. 8. Assign PASS, PARTIAL, or NOT PROVEN from evidence, not optimism. Pure structural work uses **GREEN → REFACTOR → GREEN**. ## Safety-Net Levels | Level | Evidence | Execution guidance | | --- | --- | --- | | A — Strong | Existing tests cover relevant behavior | Use tests as the primary safety net | | B — Partial | Important behavior is only partly covered | Add focused characterization of current behavior before risky steps | …

How to install
mdr add bovinphang/frontend-craft/fec-refactoring-validation@sha256:a7718a99e6c984bbThe line at the top of this page pins the label git:20260901.387d97a, 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.
