• src/index.ts:815-901 (handler)

  Handler for the 'create_folder' tool. Dynamically generates Python code using the provided arguments to create a FolderCreate object, wraps it in an Operation, and executes a transaction via the Dart client to create the folder in the specified space.

• src/index.ts:361-387 (schema)

  Input schema definition for the 'create_folder' tool, specifying parameters like space_duid (required), title (required), description, and kind.
  name: 'create_folder', description: 'Create a new folder in a space', inputSchema: { type: 'object', properties: { space_duid: { type: 'string', description: 'Space DUID to create the folder in', }, title: { type: 'string', description: 'Title of the folder', }, description: { type: 'string', description: 'Description of the folder', }, kind: { type: 'string', description: 'Kind of folder', enum: ['Default', 'Reports', 'Other'], default: 'Default' } }, required: ['space_duid', 'title'], }, },
• src/index.ts:230-513 (registration)

  Registration of all tools including 'create_folder' in the ListToolsRequestSchema handler, which returns the list of available tools with their schemas.
