The user is reporting an unexpected 'Premature close' API error after a file modification, which points to a bug in the core API client logic. The issue is not blocking the primary functionality but is a significant error, justifying a P2 priority.

I try to use it to write an article and create a .txt to save it, but fail. And i let the gemini to output the full article, it work. Then i let it to create a textfile, it also work. Finally, i told gemini save the article into the textfile, meet the same issue. Maybe long context will meet this error? The article is about 5000 words

解决办法：让cli 分步输出到文件，就可以正常执行了。猜测原因：可能就是内容太长了。过程：未知。

gemini-cli对单体大量代码的文件处理能力非常弱，等待了许久最后报错“[API Error: Premature close]”

@jacob314 Please take a look into this. This is really annoying.
