Production Go patterns for Go 1.24+ covering the full development lifecycle. Includes idiomatic concurrency with errgroup and context cancellation, error wrapping with %w, HTTP servers with Chi router, PostgreSQL with pgx, gRPC services, table-driven testing, CLI tools with Cobra, and performance profiling with pprof.

Install this skill to get production-ready Go patterns including:

• context.Context propagation for all I/O operations
• errgroup for managing concurrent goroutines safely
• Error wrapping with %w and errors.Is() / errors.As()
• Standard project layout (cmd/, internal/, pkg/)
• Worker pools, fan-out/fan-in, and select multiplexing
