@qweasdzxcpkh Hello there! I'm a bot that can help you with bug reports, answer your questions, and guide you on becoming a contributor. I'm here to assist you while waiting for a human maintainer.

To resolve the issue in Dify version 0.6.14 where the cursor automatically moves to the end of the text when editing the schema in the tools edit modal, you need to modify the onChange handler of the textarea to preserve the cursor position. Here is the updated code for the textarea component:

<textarea
  value={schema}
  onChange={e => {
    const cursorPosition = e.target.selectionStart;
    setSchema(e.target.value);
    setTimeout(() => {
      e.target.setSelectionRange(cursorPosition, cursorPosition);
    }, 0);
  }}
  className='w-full h-[240px] px-3 py-2 leading-4 text-xs font-normal text-gray-900 bg-gray-100 rounded-lg overflow-y-auto'
  placeholder={t('tools.createTool.schemaPlaceHolder')!}
/>

This change ensures that the cursor position is preserved after the state update. Additionally, you can refer to the GetSchema component in the web/app/components/tools/edit-custom-collection-modal/get-schema.tsx file for more context on how the schema is managed and imported in Dify [1][2].
