prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  src
   +--components
   +--images
   `--pages
       +--images
       `--static-images
  ```
  
  Convert this description:
  
  ssh is a origin directory that consolidates 3 subdirectories: agent, internal and knownhosts.
  At the main level, The 'agent' folder is a vacant space.
  At the top level, 'internal' keeps 1 directories: bcrypt_pbkdf.
  In nested path 'internal → bcrypt_pbkdf', Inside 'bcrypt_pbkdf', you'll find it is currently empty.
  Back to the top level.
  At the main level, Inside 'knownhosts', you'll find it contains no subdirectories.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
