Implementation Reference

• src/tools/code-assistance.ts:520-576 (handler)

  The 'refactor_helper' tool is implemented within the 'CodeAssistanceTools' class, specifically using LLM wrappers for 'suggestNames' (lines 520-576) and 'extractFunction' (lines 582-651). Both functions call 'this.llmWrapper.callToolLlm' with the identifier 'refactor_helper'.

    /**
     * Suggest better names for code identifiers
     */
    async suggestNames(
      code: string,
      options?: {
        language?: string;
        focusIdentifiers?: string[];
        style?: 'camelCase' | 'snake_case' | 'PascalCase';
      }
    ): Promise<SuggestNamesResult> {
      const language = options?.language ?? 'code';
      const style = options?.style ?? 'camelCase';
  
      const prompt = `You are an expert at naming things in code. Analyze this ${language} code and suggest better, more descriptive names for variables, functions, and classes.
  
  Naming style: ${style}
  ${options?.focusIdentifiers ? `Focus on these identifiers: ${options.focusIdentifiers.join(', ')}` : 'Analyze all identifiers that could be improved'}
