"Image Upload Failure on macOS with Screenshot Filename Format"
Bug Description The issue I encountered is claude code cannot read image from my macos. Basically I drap drop an image file from my screenshorts folder, it just cannot read it. Macos screenshot has its own special name format something like "Screenshot 2025-06-16 at 7.24.08 pm". After a few debugging, I found the solution is to use 24-hour system format. Not entirely sure if you can fix this in code level.

Errors
Error: File does not exist.
it seems the space between 08 and pm a little special.
it's true that that space is "special" in an annoying way, but we have mitigation for this. can you confirm you are on a recent version?
I have upgraded to the latest version (1.0.27). it seems the issue still there. Here is the screenshot
happy to provide more context if required
renaming it to a more "normal" file name works, but i would like to know the fix as well
Not a fix but an explanation for why 24 hour system time works.
In macOS Sonoma (14.0 and above), the standard screenshot tool uses a U+202F character instead of a regular space between the time and "AM/PM" in the filename, for instance, "Screen Shot 2025-05-13 at 11.56.52 AM.png".
When Claude calls the Read tool, it sometimes converts the whitespace automatically, e.g.

However, it seems like Claude did not do so in your screenshot.
Until we identify a fix, consider sticking with your 24-hour system time workaround or updating Apple's default screenshot path to exclude the AM/PM part.
