Description

When using the edit tool, if the oldText does not match exactly (including whitespace and newlines), the edit fails with an error. There is no staleness detection or retry mechanism.

Expected behavior

The tool should either:

1. Detect if the file was modified between read and edit
2. Provide a retry option
3. Show current file content on match failure

Related Issues

• feat: allow suppressing tool-error warnings for mutating tools (exec) #18630
• Edit tool: return current file content on match failure (optimistic concurrency) #18132

Workaround

Using exec + echo/append to write to files instead.
