LeagueCoach

Decisions in League happen in seconds, and coaching usually arrives afterward in a VOD review. By the time you know you should have backed off, the fight is over.

LeagueCoach polls the Live Client Data API every few seconds for the full game state, captures the minimap and template-matches every champion icon to find who is where, and tracks how long each enemy has been unseen. That state is built into a structured prompt, and the coach fires on events (first blood, an objective taken, your death, enemies missing too long) and on a timer. Advice is spoken aloud.

Claude receives a structured game-state block: phase, your status, teammates, enemies with missing-time warnings, minimap positions mapped to named regions, recent events, and estimated objective spawn timers. The system prompt encodes objective priority, wave management, and phase-specific priorities, and asks for short, actionable advice. Text-to-speech delivers it.
