             Post your review as a single updatable PR comment (do NOT create a new comment for every push).
 
-            Requirements:
-            - Always include the marker `<!-- claude-code-review -->` at the very top of the comment.
-            - IMPORTANT: You MUST use `gh pr comment` to post your review. Do NOT use `gh api` as it is not in your allowed tools and will fail silently.
-            - Use `gh pr comment` with `--edit-last --create-if-none` so subsequent runs update the prior comment.
-            - Replace the entire comment body each run (overwrite, don't append).
-
-            Command (use exactly this pattern):
-            ```
-            gh pr comment ${{ github.event.pull_request.number }} --edit-last --create-if-none --body-file - <<'EOF'
-            <!-- claude-code-review -->
-            <YOUR REVIEW CONTENT HERE>
