[ococl]

Summary

如图，这是出现了 DSML 标记。
有时还会出现其他非代码内容。

就目前来说，测试有问题的模型有：

• DeepSeek-V4-Flash
• Qwen3-Coder-Next

Reproduction or evidence

我的场景是配置 DeepSeek-V4-Flash 模型，然后让它生成一个PPT，提示词如下：

请帮我做一个 PPT。

主题：讲解《锄禾》
受众：混合
时长：10分钟
场景（汇报/路演/培训/分享）：分享
希望的风格（简洁/商务/活泼/极简）：活泼

最终交付：
1) 目录结构
2) 每一页的标题 + 3-5 个要点
3) 关键页的讲稿（逐页，简短即可）
4) 图表/配图建议（用什么图表达什么结论）
5) 导出为 PPTX 文件（保存到 artifacts/）

Environment, if relevant

No response

可以使用旧版Write工具规避这个问题：将配置文件C:\Users\xxx\AppData\Roaming\bitfun\config\app.json中的write_tool_mode设置为inline_content
