Implementation Reference

src/mcp/memoryBankMcp.ts:622-720 (handler)

Main handler for create_cursor_rules tool: handles directory creation, file writing, error handling, and delegates content generation to helper.

Core helper that generates Cursor rules content using AI (Gemini), detects project type, handles errors.

export async function generateCursorRules(purpose: string): Promise<string> {

  // Project type detection based on user's purpose
  const projectType = detectProjectType(purpose);

  // AI ile içerik oluştur
  try {

      purpose,
      currentDate,
      projectType
    );
    console.log("Successfully generated cursor rules with AI");
    return mainRulesContent;
  } catch (error) {

      if (error.stack) {
