diff tool call failing

[rafaeltuelho]

I see a warning

Warning: [2025-10-28T16:31:26.563Z] [Augment Agent] Failed to read file via filter, returning original path | Data: {
  "filePath": "/tmp/pr-7-diff.patch"
}

and then this error in the logs:

🔧 Tool call: view
   path: "/tmp/pr-7-diff.patch"
   type: "file"
📋 Tool result: view
❌ Error:
File not found: /tmp/pr-7-diff.patch

The bot isn't able to extract code diffs during automated PR review.
