When does this happen?

IF Editing files with pattern matching may cause unintended changes; the edit_file tool can double-apply if re-run.

How others solved it

THEN Always set dryRun: true on the edit_file tool first to review the diff and match information before applying changes. This prevents accidental data loss or corruption.

// Request: { "path": "/path/to/file", "edits": [{ "oldText": "foo", "newText": "bar" }], "dryRun": true }
// Response: diff output and match info without applying.
