        raise ValueError("sku is required")
    if quantity <= 0:
        raise ValueError("quantity must be positive")

Delay clarity until production traffic reveals the edge case and then patch it under pressure.Keep input assumptions implicit so the script stays short and hope the next engineer infers the rule.Measure before optimizing, then change the part that actually dominates cost instead of guessing from style alone.Solve the symptom with comments only and avoid changing the code shape around input assumptions.
