Edit tool proceeds despite user rejection

Description

When I reject an Edit tool call, the edit appears to go through anyway. I then had to ask Claude to change it back.

Steps to reproduce

1. Claude attempts to edit a file (e.g., changing a task label in .vscode/tasks.json)
2. User explicitly rejects the edit
3. The file is modified anyway despite the rejection

Expected behavior

When I reject an Edit tool call, the file should remain unchanged.

Actual behavior

The edit was applied to the file despite explicit rejection. Claude then had to make another edit to restore the original content.

Specific example

Claude attempted to change:

"dependsOn": ["Update Python UV lockfiles and dependencies"]

to:

"dependsOn": ["Sync Python dependencies"]

I rejected this edit, but the file was changed anyway. Claude later had to edit it back to the original.

Environment

• Claude Code version: 2.1.17
• OS: macOS Darwin 25.2.0
• Model: claude-opus-4-5-20250101
