Realtime

The main gotcha is that RLS policies filter every event per user, so if clients connect but receive nothing, it's almost always missing or overly restrictive row-level security, not a broken WebSocket. The skill exposes manage_realtime for enabling tables and inspecting trigger state, plus detailed protocol docs for presence tracking and multiplayer state. Most valuable when you're adding collaborative features or chasing down why events aren't flowing, since the RLS enforcement model is silent by design and trips up everyone at least once.
