Model Selection Command Implementation

Objective

Add a /model command to the Forge CLI that uses the inquire library to display a list of available models and update the project's forge.yaml file with the selected model.

Implementation Plan

• Add inquire as a dependency to the workspace and forge_main crate
• Implement a handle_model_selection() method in the UI module to:
  • Fetch available models using the API
  • Display a selection interface using inquire
  • Update the forge.yaml file with the selected model
• Update the Command::Model match case to call the new method

Implementation Details

1. Added inquire dependency to the workspace and forge_main Cargo.toml files
2. Implemented a new handle_model_selection() method in the UI module that:
   • Fetches the list of available models
   • Uses inquire to display a selection list
   • Updates the standard_model anchor in the forge.yaml file
3. Updated the Command::Model case in the UI::run method to call the new method

Verification Criteria

• The /model command should display a list of available models using inquire
• After selecting a model, the forge.yaml file should be updated with the selected model
• The standard_model anchor in the forge.yaml file should be created if it doesn't exist
• Appropriate error messages should be displayed if any step fails

Potential Risks and Mitigations

• Risk: Models API might return an empty list Mitigation: Added error handling for empty model lists
• Risk: forge.yaml file might not exist in the current directory Mitigation: Added error handling for missing files
• Risk: forge.yaml file might be in an unexpected format Mitigation: Added error handling for parsing errors

Future Improvements

• Add support for updating advanced_model in addition to standard_model
• Add support for creating forge.yaml if it doesn't exist
• Add ability to filter models by provider
