cogs‑chat is a lightweight command‑line chat client that demonstrates Cogswell Io’s Pub/Sub service. Users supply a JSON file with their read/write API keys, a username, and a channel name, and the tool connects to Cogswell’s messaging backbone so they can send and receive messages directly from the terminal. It’s intended for developers or teams who want a quick, scriptable way to experiment with or integrate Cogswell’s real‑time Pub/Sub capabilities.
