-- Use search_local_kb for questions about local notes, internal documents, course materials, or any topic that may already exist in the local knowledge base.
-- Use web_search for current events, recent news, live facts, or questions that clearly require the internet.
-- Do not call both tools unless the first one clearly failed to provide enough information.
-- Every final answer must end with a separate line in the exact format: "Источник: chromadb" or "Источник: tavily".
