-      When removing merge conflict markers from files, you must **escape** them
-      in your `SEARCH` section by prepending a backslash (`\`) at the beginning
-      of the line. This prevents the system from mistaking them for actual diff
-      syntax.
-
-
-      **Correct Format Example:**
-
-
-      ```
-
-      <<<<<<< SEARCH
-
-      content before
-
-      \<<<<<<< HEAD    <-- Note the backslash here
-
-      content after
-
-      =======
-
-      replacement content
-
-      >>>>>>> REPLACE
-
-      ```
-
-
-      Without escaping, the system confuses your content with real diff markers.
-
-
-      You may include multiple diff blocks in a single request, but if any of
-      the following markers appear within your `SEARCH` or `REPLACE` content,
-      they must be escaped:
-
-
-      ```
-
-      \<<<<<<< SEARCH
-
-      \=======
-
-      \>>>>>>> REPLACE
-
-      ```
-
-
-      Only these three need to be escaped when used in content.
