Set up Fight Brief alerts for me. Check https://fightbrief.com/agents/updates.json once an hour. When there's a new article or a real correction, send me the headline, a one-line summary and the link. If nothing changed, stay quiet.

Feed details are at https://fightbrief.com/llms.txt. Don't alert me about articles that are already up when you start; send one message marked TEST with the latest article so I know it works.

When you're done, tell me in a sentence or two: how often you'll check, where alerts will show up and how to pause them. If you can't run scheduled tasks or send me messages, just say so. If checks keep failing, tell me once, in plain words.
