websocket-pro
WebSocket (professional)
Skill text is English; answer in the user’s preferred language when rules or the conversation specify it.
Use official RFC 6455, MDN WebSocket API, and WHATWG WebSockets for standards truth; this skill encodes production reliability defaults, message-contract discipline, and operational failure modes. Confirm deployment topology (single node vs cluster), client behavior, and delivery/latency requirements from the project.

websocket-pro owns connection semantics, message contracts, reconnect/backpressure patterns, and transport vs SSE/long-poll choice at the architecture level. deployment-pro / network-infra-pro own ingress/LB/proxy specifics; security-pro owns threat/abuse depth; api-design-pro owns idempotent command design for duplicate delivery.
