Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
Model will attempt to edit files with broken filenames, say at
/project/project-name-name/file.ext
When the real path is
/project/project-name/file.ext
It throws up a request to edit file, with only the final ‘file.ext’ part. You have to hover over the filename to see a tooltip, which due to this being caused by hallucination, looks correct, but is subtly wrong. I’ve seen it off by a single character, by dropping a character and by repeating a suffix.
“External-File Protection” is enabled, so this shouldn’t be happening.
Steps to Reproduce
Get the model to edit a filename, sometimes it doesn’t work.
Expected Behavior
File edits for files that don’t exist should be automatically denied regardless of “External-File Protection”, since it’s certainly an error.
File edits outside the workspace should be automatically denied when “External-File Protection” is enabled.

For AI issues: add Request ID with privacy disabled
Due to policy I can’t provide this, but this should be fixable with better tooling.
