- Introduce a new `RuntimeTool` model to encapsulate tool data for runtime sessions, including attributes like `id`, `name`, `function_name`, `type`, and `description`. - Update the `AssistantConfig` model to include a list of reusable tools, allowing for better management of tools within assistant configurations. - Modify the `config_resolver` service to fetch and resolve tools associated with assistants, ensuring they are available during runtime. - Refactor tool-related CRUD operations in the `tools` route to support the new runtime execution model, enhancing the overall tool management system. - Update documentation and comments to reflect changes in tool execution and configuration handling, improving clarity for future development.
