+# Clean Code — Cursor Rules
+
+# Pragmatic coding standards: concise, direct, no over-engineering.
+
+## Core Principles
+- Follow SRP: each function/class does ONE thing
+- Follow DRY: extract duplicates, reuse shared logic
+- Follow KISS: always choose the simplest solution that works
+- Follow YAGNI: never build features that aren't needed yet
+- Leave code cleaner than you found it (Boy Scout Rule)
+
+## Naming
+- Variables must reveal intent: `userCount` not `n`
+- Functions use verb+noun: `getUserById()` not `user()`
+- Booleans use question form: `isActive`, `hasPermission`, `canEdit`
+- Constants use SCREAMING_SNAKE: `MAX_RETRY_COUNT`
+- If a name needs a comment to explain it, rename it
+
+## Functions
+- Keep functions under 20 lines, ideally 5–10
+- Each function does one thing at one level of abstraction
+- Max 3 arguments, prefer 0–2
+- Never mutate inputs unexpectedly
+
+## Structure
+- Use guard clauses and early returns for edge cases
+- Keep nesting to max 2 levels — flatten with early returns
+- Compose small functions together
+- Colocate related code
+
+## Anti-Patterns — Never Do These
+- Do not comment every line — delete obvious comments
+- Do not create helpers for one-liners — inline the code
+- Do not create factories for 2 objects — use direct instantiation
+- Do not create `utils.ts` for a single function — put code where it's used
+- Do not use magic numbers — use named constants
+- Do not write god functions — split by responsibility
+
+## Before Editing Any File
+- Check what imports this file — dependents might break
+- Check what this file imports — interfaces may change
+- Check what tests cover this file — tests might fail
+- Edit the file AND all dependent files in the same task
+- Never leave broken imports or missing updates
+
+## Self-Check Before Completing
+- Verify the goal is met — did you do exactly what was asked?
+- Verify all necessary files are modified
+- Verify lint and type checks pass
+- Verify no edge cases are missed
