If the file was modified in the last 3 commits on the base branch, warn the user that a rebase will likely conflict and suggest completing the split in a fast follow-up PR to minimize conflict surface.
 1. One refactoring at a time. Do not combine unrelated changes.
 2. Preserve all existing behavior. Refactoring changes structure, not behavior.
 3. Follow existing code style and conventions in the project.

+### Large Diff Handling
+
+If the diff exceeds 30KB, save it to a temp file instead of passing it inline:
+
+```bash
+git diff {base}...HEAD > /tmp/review-diff-{branch}.txt
+```
+
+Then replace the `FULL DIFF` section in the briefing with:
+
+```
+FULL DIFF: Read the diff from /tmp/review-diff-{branch}.txt
+```
+
+This prevents context window overflow in reviewer agents.
