The check is made after parts like `.` (this folder) and `..` (the folder above) in the path are worked out. When it fails, the tool returns an error saying the path ends in white space.\n\n**Why**\n\nA path with a stray space at the end can quietly point to a different file from the one intended. Refusing it stops Claude from reading or writing the wrong file by accident.\n\n- Area: File Tools\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: yes"}
