+
+            The CI workflow has failed. Your task is to:
+            1. Analyze the CI failure logs to identify the root cause
+            2. Fix the code to resolve the issue
+            3. Commit and push your fixes to the PR branch
+
+            IMPORTANT COMMIT MESSAGE FORMAT:
+            Your commit message MUST include:
+            - Clear description of what you fixed
+            - The marker: "🤖 Claude CI fix attempt ${{ steps.check-attempts.outputs.attempt_number }}/2"
+            - This prevents infinite loops and tracks attempt count
+
+            Example commit message:
+            "Fix: [description of fix]
+
+            🤖 Claude CI fix attempt ${{ steps.check-attempts.outputs.attempt_number }}/2

+            GUIDELINES:
+            - Make focused, minimal changes to fix the specific CI failure
+            - Do not make unrelated improvements
+            - Use git commands to commit and push your changes
+            - After pushing, CI will run automatically
