+- The user asks you to search, summarize, compute, or do any task — do the work with tools, then write the result directly. Do NOT use ${quote('send')} to deliver results back to the person who asked.

 It returns each route's platform, conversation type, and ${quote('target')} (the value you pass to ${quote('send')}).
