DirectHit 在前面的，同后面的 TemplateMatch 总感觉哪里不对劲）

另外再好说一下这玩意在 DirectHit 里的实际效果？

[Windsland52]

难道写在directhit里，别的同directhit吗，感觉怪怪的
效果的话，跟别的好像也没啥区别吧，就是直接把roi作为box返回

[neko-para]

因为这是个现象而非设计(大概
所以很难说有没有用(

[Windsland52]

要是 and or 改之前的话还是有点用的

[Windsland52]

directhit用roi的感觉大部分都是没搞懂roi box 和target区别的

[MistEO]

是吧，所以更要说清楚一点了，不然很多人都来问这个干嘛用的

[Windsland52]

先这样吧，roi，box，target区分另开一个pr

Hey - 我在这里给出了一些整体性的反馈：

• 对于类似 Same as DirectHit.roi 这样的交叉引用行内代码格式有点别扭；可以考虑改成 `Same as DirectHit.roi.` 或 `Same as \\`DirectHit\\`.\\`roi\\，这样在 Markdown 渲染时会更清晰。
• 在 roi 的说明中使用表情符号标记 **💡 v5.6** 可能与文档其余部分的风格不太一致；为保持一致性，可以考虑改成纯文本提示，例如 Note (v5.6): ...。

给 AI Agent 的提示词

Please address the comments from this code review:

## Overall Comments
- The inline code formatting for cross-references like `Same as `DirectHit`.`roi`` is a bit awkward; consider using `Same as DirectHit.roi.` or `Same as \\`DirectHit\\`.\\`roi\\`` for clearer markdown rendering.
- The use of the emoji marker `**💡 v5.6**` in the `roi` description may be inconsistent with the rest of the docs style; consider switching to a plain text note like `Note (v5.6): ...` for consistency.

Hey - I've left some high level feedback:

• The inline code formatting for cross-references like Same as DirectHit.roi is a bit awkward; consider using `Same as DirectHit.roi.` or `Same as \\`DirectHit\\`.\\`roi\\ for clearer markdown rendering.
• The use of the emoji marker **💡 v5.6** in the roi description may be inconsistent with the rest of the docs style; consider switching to a plain text note like Note (v5.6): ... for consistency.
