What It Enforces

Go Proverbs (All 19)

• "Clear is better than clever"
• "Errors are values"
• "The bigger the interface, the weaker the abstraction"
• "Don't panic"
• And 15 more...

Domain-Specific Rules

• Error Handling: Always wrap with context, never ignore
• Interface Design: Small interfaces, consumer-defined, accept interfaces return structs
• Concurrency: Every goroutine has a known lifecycle, context propagation
• Naming: No Get prefix, no stutter, no util packages
• Testing: Table-driven, subtests, t.Helper()

Red Flags & Anti-Patterns

• 30+ red flags to catch
• Code examples of what NOT to do
• Rationalization counters for common excuses
