Product title not a placeholder

Each Product title is not a known placeholder (Default Title, Untitled, Product 1, …) and not a slug-shape token (e.g. `red-hat-001`). Placeholder titles like Default Title make products look broken to agents.

What this check looks for

Agents look for human-meaningful titles. The legacy regex flagged any short alphanumeric string as a placeholder, which false-positived on legitimate short words like "Bag" or "Red". v2 tightens the rule: we fail only if the title is empty, matches a known placeholder list ("Default Title", "Untitled", "Product 1", "sample", "test", etc.), or matches a slug shape (lower-case alphanumerics with at least one hyphen). Single short words pass. Coverage ≥ 95% passes; ≥ 70% partial; otherwise fail.

How to fix it

Replace placeholder and slug-shape titles with real product names

const PLACEHOLDERS = new Set([
  "untitled product", "untitled", "new product", "default title",
  "sample", "sample product", "test product", "test",
  "draft product", "draft", "placeholder", "placeholder product",
]);
const SLUG_RE = /^[a-z0-9]+(?:-[a-z0-9]+)+$/;
const PRODUCT_N_RE = /^product\s+\d+$/i;

function isPlaceholderTitle(name: string): boolean {
  const t = name.trim();
  if (t.length === 0) return true;
  if (PLACEHOLDERS.has(t.toLowerCase())) return true;
  if (PRODUCT_N_RE.test(t)) return true;
  if (SLUG_RE.test(t)) return true;
  return false;
}

The spec it's pinned to

• schema.org/Product.name (quality)

  schema.org doesn't quantify quality, but agents reject obvious placeholders (Default Title, Untitled, Product 1) and slug-shape names that look like internal IDs.
