What's Wrong?

Files over some size threshold (in my skill's case, a file >614 lines / >23,458 bytes) get cut off in the Linux-sandbox view, preventing skill from executing on Windows.

What Should Happen?

The read that Claude performs via the linux-sandbox view should return the same results as the Windows read, allowing the skill to execute correctly.
