Before implementing new functionality, check if similar utilities or patterns already exist in the codebase. Consolidate duplicate logic and leverage existing libraries to maintain consistency and reduce maintenance overhead. Key practices: - Search the codebase for existing utilities before creating new ones (e.g., use existing `ansi.Strip` instead of implementing `util.StripAnsi`) - Combine similar functionality rather than creating separate handlers (e.g., add `ctrl+p` to existing `Up` binding instead of creating separate `CtrlP` binding) - Move expensive operations to appropriate lifecycle methods to avoid repeated execution in frequently called functions Example: ```go // Instead of creating new utility out := util.StripAnsi(fmt.Sprintf("%s", stdout)) // Reuse existing library out := ansi.Strip(fmt.Sprintf("%s", stdout)) ``` This approach improves code maintainability, reduces duplication, and ensures consistent patterns across the codebase.
