The **cogs-pubsub-dialect** package provides a set of Joi‑based validators for the JSON structures used by Cogswell’s Pub/Sub API. It lets developers (primarily backend engineers integrating with Cogswell’s messaging service) verify request and response objects—such as subscribe/unsubscribe directives, publish commands, and error payloads—ensuring they conform to the official Pub/Sub dialect before sending or processing them.
