Crafting a news brief

I’m thinking about responding with a concise news brief that mentions it’s being reported by Latin American outlets, noting that there aren’t any official bids yet. The player in question is a 17-year-old Ecuadorian midfielder named Castillo. I’ll acknowledge this is just a rumor and ask for more specifics like his full name or club. I can offer a short template with context on transfer rules and possible fees, and check sources if they provide a link. Also, I’m considering the sandbox setup for web searching.Planning the response

I'm considering that the CLI harness might not allow web browsing via curl; however, I can use shell and network options. It’s probably best to ask the user if they want me to look up sources. Following the "Ask only when needed" guideline, I can keep it casual with a one-liner style.

I'll summarize the rumor briefly, ask which Castillo they mean, and offer to verify through sources or write a quick news brief. I'll also create a concise message in Chinese while keeping it brief.
