qa-refactoring SKILL.md skillA
qa-refactoring from vasilyu1983/ai-agents-public is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vasilyu1983/ai-agents-public/qa-refactoring@v1.1Pins v1.1 in mdr.lock. Pin the fingerprint instead.

Refactors code while preserving behavior. Use when reducing technical debt, planning codemods, applying strangler migrations, or tightening CI guardrails around risky changes.
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
# QA Refactoring Use this skill to refactor safely: preserve behavior, reduce risk, and keep CI green while improving maintainability and delivery speed. Defaults: baseline first, smallest safe step next, and proof via tests/contracts/observability instead of intuition. ## Quick Start (10 Minutes) - If key context is missing, ask for: what must not change (invariants), risk level (money/auth/migrations/concurrency), deployment constraints, and the smallest boundary that can be protected by tests. - Confirm the target branch is green; reproduce the behavior you must preserve. - Choose a boundary: API surface, module boundary, DB boundary, request handler, or codemod blast radius. - Add a safety net: characterization/contract/integration tests at that boundary. - Refactor in micro-steps: one behavior-preserving change per commit/PR chunk. - Prove: map each preserved behavior to an oracle and execution layer; where practical, show the oracle fails on the faulty or removed behavior, then passes on the refactor. Run the smallest relevant suite locally, then full CI; keep failures deterministic and artifact-rich. ## Workflow …

How to install
mdr add vasilyu1983/ai-agents-public/qa-refactoring@sha256:dd1ea2b77d9a9310The line at the top of this page pins the label v1.1, 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.
