Search Costory product docs (Mintlify) and knowledge base in parallel. Synthesize both: Mintlify is the product source of truth, the KB complements with org-specific or internal detail; if they conflict, trust Mintlify. Returns Mintlify matches (titles, snippets, and full docs URLs (`Url: https://docs.costory.io/...`)) and KB articles (title, summary, full markdown). Optional limit (1–10, default 5) applies to KB. For a full Mintlify page, use get_documentation_page. When citing a page in chat, use the full `Url:` value verbatim as the markdown href — do not convert to a relative app path.
EXAMPLES:
• "How do I create a budget alert?" → { query: "budget alert" }
• "Why do costs differ from AWS Cost Explorer?" → { query: "AWS Cost Explorer discrepancy", limit: 3 }
