networking-transport

What problem does it solve?

This Skill prevents fragile, high-latency, hard-to-debug production networking by guiding transport and wire-format decisions that directly affect tail latency, connection stability, and interoperability.

Core Features & Use Cases

• Connection lifecycle and keepalive tuning: Ensures long-lived TCP/TLS connections stay healthy behind cloud load balancers by setting keepalive intervals and proper pooling behavior.
• Protocol selection and head-of-line blocking analysis: Explains when HTTP/1.1, HTTP/2, or HTTP/3 (QUIC) will perform well or fail under packet loss and cross-region latency.
• Wire protocol and schema guidance: Helps choose REST/JSON vs gRPC/Protobuf vs Connect, and provides protobuf evolution essentials to avoid wire-incompatible changes.
• Long-lived connection patterns: Covers websockets, SSE, gRPC streaming, and long-polling with a focus on idle-timeout realities and operational gotchas.
• Operational review checklist: Provides reviewer guardrails for client reuse, timeout strategy, retry bounds, and gRPC channel reuse.

Quick Start

Use the networking-transport skill to review your service-to-service API and propose the correct HTTP/gRPC/streaming approach while specifying keepalive and idle-timeout settings for your load balancer and clients.
