Indexed from public GitHub and served as immutable, content-addressed versions.

The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Refactoring Patterns Skill

> Safe transformations — same behavior, better structure.

## Golden Rule

Tests pass before AND after. Never refactor and add features in the same commit.

## When to Refactor

| Trigger | Action |
| ------- | ------ |
| Feature is hard to add | Refactor first, then add feature |
| Same bug twice | Refactor to prevent recurrence |
| "I don't understand" | Refactor for clarity |
| Duplicate code | Extract and reuse |
| Long function (>30 lines) | Extract logical units |

## When NOT to Refactor

- No tests + time pressure
- Code won't change again
- Right before release (deadline pressure)
- Should rewrite instead (>70% changes needed)
- Exploratory/prototype code

## Core Refactoring Moves

### Extract Function

When a block does one logical thing, give it a name.

```typescript
// Before
function processOrder(order: Order) {
  // Validate order
  if (!order.items.length) throw new Error('Empty order');
  if (!order.customer) throw new Error('No customer');
  if (order.total < 0) throw new Error('Invalid total');
  
  // Calculate tax
  const taxRate = order.region === 'EU' ? 0.20 : 0.10;
  const tax = order.total * taxRate;
  
  // Apply discount
…
