Principles

• Keep it simple (KISS) — prefer the simplest solution that works
• Don't repeat yourself (DRY) — extract when you see three duplicates, not before
• Single Responsibility — each module/function does one thing
• Use descriptive, intention-revealing names
• Use kebab-case for files and folders
• Functions should have clear inputs and outputs with minimal side effects
• Keep functions right-sized — extract when logic needs a comment to explain
• Delete dead code — don't comment it out
• Never swallow errors silently
• Measure before optimizing — no premature performance work
• No premature abstraction — wait for three concrete duplicates before extracting
