- Introduce a new `Tool` model and `AssistantToolBinding` for managing reusable tools within the application. - Implement CRUD operations for tools in the new `tools` route, allowing for the creation, retrieval, updating, and deletion of tools. - Update the `Assistant` model to include a list of tool IDs, enabling assistants to utilize these tools. - Enhance the backend routes to synchronize tool bindings with assistants, ensuring proper management of tool associations. - Add frontend components for tool management, including a tool picker in the assistant configuration, improving user experience in tool selection. - Create a mobile call page to facilitate video calls, integrating camera and microphone selection for enhanced communication capabilities. - Update API definitions to include tool-related types and operations, ensuring consistency across the application. - Add a migration script to create the necessary database tables for tools and bindings, supporting the new functionality.
