refactoring-patterns from akaszubski/autonomous-dev is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add akaszubski/autonomous-dev/refactoring-patterns@git:20260317.e64d556Pins git:20260317.e64d556 in mdr.lock. Pin the fingerprint instead.

Safe refactoring techniques — extract, inline, rename, move, simplify conditionals, and decompose functions. Use when restructuring code without changing behavior. TRIGGER when: refactor, extract method, rename, inline, simplify, decompose, clean up, code smell. DO NOT TRIGGER when: adding features, fixing bugs, writing tests, documentation.
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
# Refactoring Patterns
Safe techniques for restructuring code without changing its behavior. Every refactoring follows: test green -> refactor -> test green.
## Golden Rule
**Never refactor and change behavior in the same commit.** Refactoring = same behavior, different structure. Feature work = different behavior. Mixing them makes bugs untraceable.
## Pre-Refactoring Checklist
Before any refactoring:
- [ ] Tests exist and pass for the code being refactored
- [ ] You can describe what the code does WITHOUT reading it line by line
- [ ] The refactoring has a clear motivation (not "it could be cleaner")
- [ ] The scope is bounded — you know exactly which files/functions change
## Core Refactorings
### 1. Extract Function
**When**: A code block does one identifiable thing, or you need to add a comment explaining what a block does.
```python
# BEFORE
def process_order(order):
# Validate order
if not order.items:
raise ValueError("Empty order")
if order.total < 0:
raise ValueError("Negative total")
if not order.customer_id:
raise ValueError("Missing customer")
# Apply discounts
total = order.total
if order.is_member:

How to install
mdr add akaszubski/autonomous-dev/refactoring-patterns@sha256:a51c2c99aed1cdfaThe line at the top of this page pins the label git:20260317.e64d556, 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.
