  perform_paste_from_clipboard method and a paste_from_clipboard tool.

  prompt template and updated README documentation.

  matching a block, with an optional content filter to skip empty messages.

  last response has been successfully copied to the system clipboard.”

  Conversation#load_conversation to quote Pathname objects correctly in
