+            Apply the code suggestions from Claude's PR review on PR #${{ github.event.pull_request.number }} in repo ${{ github.repository }}.
+
+            Steps:
+            1. Fetch Claude's inline review comments:
+               gh api repos/${{ github.repository }}/pulls/${{ github.event.pull_request.number }}/comments \
+                 --jq '[.[] | select(.user.login == "claude[bot]")]'
+            2. For each comment, check if it contains a concrete code suggestion (e.g. a code block showing a proposed change, a specific line replacement, etc.)
+            3. Apply each concrete suggestion to the corresponding file and location
+            4. Skip any comment that is purely informational, raises an architectural concern, asks a question, or requires a product decision
+            5. If any changes were made:
+               git add -A
+               git commit -m "chore: apply Claude review suggestions"
+               git push
+            6. If no actionable code suggestions exist, do nothing - no commit needed
+
+            IMPORTANT: Only apply clear, unambiguous code-level changes. Do not implement new features, refactor beyond what is explicitly suggested, or make any judgment calls.
