Directory Configuration Tool

Build a command-line configuration utility that helps users select directories for application settings. The tool should collect three directory paths from the user and save them to a configuration file.

Requirements

The utility should prompt the user to select three directories:

1. Project directory: The main project working directory (must be a directory only, not a file)
2. Output directory: Where generated files will be saved (must be a directory only, not a file)
3. Cache directory: Where temporary cache files will be stored (must be a directory only, not a file)

After collecting all three directory paths, save them to a JSON configuration file named config.json with the following structure:

{
  "project_dir": "/path/to/project",
  "output_dir": "/path/to/output",
  "cache_dir": "/path/to/cache"
}

Implementation

@generates

The program should:

• Display clear prompts for each directory selection
• Only allow users to select directories (not individual files)
• Validate that the selected paths exist
• Write the configuration to config.json in the current working directory

Test Cases

• The tool prompts for project directory and only allows selecting directories @test
• The tool prompts for output directory and only allows selecting directories @test
• The tool prompts for cache directory and only allows selecting directories @test
• The tool saves all three directory paths to config.json in the correct format @test
