Community default. A project skill or agent-config rule that explicitly supersedes go-design-patterns takes precedence over this one.

Detailed reference material, loaded on demand:

• references/creation-patterns.md — functional options (full example), options vs config struct, constructors, factory.
• references/behavioral-patterns.md — strategy, middleware/decorator, result type, defer cleanup, sentinel vs zero values.
• references/resilience-and-types.md — retry with jitter, circuit breaker, bulkhead, parse-don't-validate types, status types.
