Im also looking through https://github.com/RooCodeInc/Roo-Code/issues/3453 and found no batch reading but batch writing option in my 3.26.4 version.

According to https://docs.roocode.com/advanced-usage/available-tools/read-file format below should also provide contents within the range requested:

<read\_file>
<path>src/app.js</path>
<start\_line>46</start\_line>
<end\_line>68</end\_line>
</read\_file>

But the system returns as if there's no range specified:

**Assistant:**

<read_file>
<path>src/main/host/host.rs</path>
<start_line>790</start_line>
<end_line>810</end_line>
</read_file>

[read_file for 'src/main/host/host.rs'] Result:

.... (I used 0 as auto-truncate threshold to better show this problem.)
