golang-services

Production Go service patterns: the wiring that turns a correct package into a service that survives deploys, load, and 3 a.m. incidents. Covers the hardened net/http server shape (all four timeouts, no default client/server), middleware chains, graceful shutdown under SIGTERM with bounded drain, timeouts at every boundary (inbound, outbound, database), gRPC and JSON API structure, config and env wiring read once in main, structured logging with slog (request IDs, no secrets), liveness versus readiness probe semantics, OpenTelemetry traces and metrics on ingress and egress, and the standard service repo layout. Complements golang-patterns (code discipline) and golang-testing (proof): this skill owns the boundary between the binary and production. Use when scaffolding a Go service, wiring main.go, adding middleware or probes, setting any timeout, or reviewing service deployment readiness.
