Developer Builds LLM-Powered Sleep Monitor for World Cup

A developer created Nightwatch, a system that uses Cloudflare Workers and an LLM to filter World Cup match events and only alert him when something is worth waking up for. The tool pulls from ESPN's undocumented API, uses a deterministic gate to confirm events, and calls Claude Haiku to judge significance before sending a Telegram alert. During a demo replay of Argentina vs Switzerland, it correctly identified 4 high-significance events out of 9 total alerts.
