Make Claude Code stop over-commenting.

// CHANGED: Added input validation to ensure
// both parameters are finite numbers, and now
// throws TypeError if validation fails.
// Previously had no validation.
export function add(a, b) {
  // Check if 'a' is a finite number using
  // Number.isFinite()
  // This returns false for Infinity, -Infinity,
  // NaN, and non-numeric values
  if (!Number.isFinite(a)) {
  ...

export function add(a: number, b: number) {
  // Finite validation required because NaN and
  // Infinity are technically numbers in JS
  if (!Number.isFinite(a)) {
    throw new TypeError(...);
  }
  if (!Number.isFinite(b)) {
    throw new TypeError(...);
  }
  return a + b;
