# web-search — fresh, cited answers ## When to use Trigger when the question depends on **current state**: - prices, rates, exchange rates, stock quotes, ETF NAV - recent news (last 6 months) - newly released product specs, library versions - regulations / policies that may have changed - comparison ("X vs Y") where one side could have shipped updates Do NOT use for stable facts (math, history, well-settled science) — answer directly.
