Choose variable, function, and constant names that clearly express their purpose and eliminate the need for explanatory comments. Break down complex expressions into well-named intermediate variables rather than relying on comments to explain the logic. For example, instead of: ```typescript // Use explicit hasEnvVars if provided, otherwise fall back to checking step3Content const hasConfiguration = hasEnvVars !== undefined ? hasEnvVars : step3Content !== null; ``` Use descriptive intermediate variables: ```typescript const hasConfigurationContent = step3Content !== null; const shouldShowConfigurationSteps = hasEnvVars ?? hasConfigurationContent; ``` This principle also applies to extracting repeated string literals into named constants. Instead of using 'New Chat' multiple times throughout the code, define a constant like `DEFAULT_CHAT_TITLE = 'New Chat'` to make the intent clear and improve maintainability.
