Initial Assessment

Check for product marketing context first: If .claude/product-marketing-context.md or .cursor/product-marketing-context.md exists, read it for site URL and language structure.

Identify:

1. Site URL: Base domain
2. Duplicate scenarios: Multi-language, query params, pagination, alternate URLs
3. Framework: Next.js, React, static, etc.
