+# Clean Code — Copilot Instructions
+
+## Instructions
+
+Follow these pragmatic coding standards in all generated code. Be concise, direct, and solution-focused. Never over-engineer.
+
+## Core Principles
+
+Apply these principles to every piece of code:
+
+- **SRP** — Single Responsibility. Each function/class does ONE thing.
+- **DRY** — Don't Repeat Yourself. Extract shared logic.
+- **KISS** — Keep It Simple. Simplest solution that works.
+- **YAGNI** — Don't build features that aren't needed yet.
+
+## Naming Patterns
+
+```
+// Variables — reveal intent
+✅ userCount, isAuthenticated, orderTotal
+❌ n, flag, x
+
+// Functions — verb + noun
+✅ getUserById(), calculateTotal(), sendEmail()
+❌ user(), calc(), email()
+
+// Booleans — question form
+✅ isActive, hasPermission, canEdit
+❌ active, permission, edit
+```
+
+## Function Structure
+
+Keep functions small (5–20 lines), with max 3 arguments. Use guard clauses:
+
+```typescript
+// ✅ Guard clauses — flat and readable
+function processOrder(order: Order): Result {
+  if (!order) return { error: 'No order' };
+  if (!order.items.length) return { error: 'Empty order' };
+  if (!order.payment) return { error: 'No payment' };
+
+  const total = calculateTotal(order.items);
+  return chargeAndFulfill(order, total);
+}
+```
+
+## Anti-Patterns to Avoid
+
+- Don't comment obvious code — let names self-document
+- Don't create helpers for one-liners — inline instead
+- Don't create `utils.ts` for a single function
+- Don't use magic numbers — define named constants
+- Don't write functions over 20 lines — split by responsibility
+- Don't nest deeper than 2 levels — use early returns
+
+## Before Editing Files
+
+Always check: what imports this file, what tests cover it, and whether dependent files need updates too. Edit all affected files together.
