From e84d00fb0d0d581fcbbad20ce6614f716b6fa27b Mon Sep 17 00:00:00 2001 From: MyPrototypeWhat Date: Mon, 1 Sep 2025 16:04:38 +0800 Subject: [PATCH] refactor(aiCore): restructure parameter handling and file processing modules - Removed the transformParameters module and replaced it with a more organized structure under prepareParams. - Introduced new modules for file processing, model capabilities, and parameter handling to improve code maintainability and clarity. - Updated relevant imports across services to reflect the new module structure. - Enhanced logging and error handling in file processing functions. --- .../src/aiCore/prepareParams/fileProcessor.ts | 192 ++++++ .../src/aiCore/prepareParams/index.ts | 22 + .../aiCore/prepareParams/messageConverter.ts | 170 ++++++
