Hey, thanks for the report. This is a known issue, and the team is already working on a fix.
The Write and StrReplace tools get blocked when trying to edit .cursor/rules without showing a confirmation prompt, even though they should ask for the user’s permission.
Detailed discussion and workarounds: [BUG] AI Agent Write/StrReplace Tools Blocked on .cursor/rules/private/*.mdc Files
Temporary workaround (from the linked thread):
cp .cursor/rules/file.mdc tmp_file- Edit
tmp_fileusing the agent - Confirm the changes
- `mv tmp_file .cursor/rules/file.mdc
