prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  es_declare_module
   +--__snapshots__
   `--flow-typed
       `--__snapshots__
  ```
  
  Convert this description:
  
  app is a base directory that features 2 subdirectories: api and posts.
  In the root directory, 'api' groups 3 directories: disable-draft, draft, revalidate.
  At level 2, in directory path 'api > disable-draft', 'disable-draft' is blank.
  Within directory hierarchy 'api / draft', The 'draft' storage space sits empty.
  Within directory hierarchy 'api → revalidate', 'revalidate' stands empty.
  Back to the top level.
  At the main level, 'posts' encapsulates 1 folders: [slug].
  In nested path 'posts / [slug]', The '[slug]' compartment contains nothing at present.
