Developer's prompt tames Claude's over-engineering reflex

A developer has found a specific instruction to be highly effective in guiding Claude's coding behavior, preventing it from over-engineering solutions. By adding the line "Default to the smallest change that fits. Add abstractions only after the second occurrence, never the first." to a CLAUDE.md file, the developer observed a significant reduction in Claude's tendency to create overly complex code architectures. This simple directive appears to counteract Claude's ingrained reflex for premature abstraction, leading to more concise and appropriate code generation. AI
