• Code review feedback
• Questions about style guidelines

Commands

bun x ultracite fix     # Format and fix
bun x ultracite check   # Check for issues
bun x ultracite doctor  # Diagnose setup

Quick Fix

Most issues are auto-fixed:

bun x ultracite fix

Console Logging

• Never use console.log, console.debug, or console.info in production code
• Only use console.error and console.warn for actionable errors
• For debug logging, wrap in if (IsDev) { ... }
• Don't use biome-ignore to suppress console warnings - remove the logs instead

Rules

See rules/ directory for detailed guidance.
