Costs 5 credits; use search when you already know the engine.
Present already retrieved source results as source cards when the host supports UI, with a complete readable text list otherwise. Use when the user wants to browse sources or a visual list helps the task. Pass existing results in the desired order; never invent source URLs or factual titles.
