What is web search tool?
Web search tool: A tool that lets an agent query a search engine or search API and read returned snippets or pages. It gives the model fresh information beyond its training data, but results must be checked because pages may be wrong or hostile.
Web search tool: an example
Asked for today's Sensex close, the agent calls web_search('Sensex closing today') and quotes the top financial result.
