+              
+              **Commit**: ${sha}
+              **Commit Message**: ${commitMessage}
+              **Branch**: main
+              **Workflow**: [End-to-End Tests](${context.payload.repository.html_url}/actions/runs/${context.runId})
+              
+              The end-to-end tests failed after merging to the main branch. This indicates that the latest changes may have introduced issues with the core proxy functionality.
+              
+              ### Next Steps
+              1. Review the [failed workflow logs](${context.payload.repository.html_url}/actions/runs/${context.runId})
+              2. Check if this is a flaky test or a real issue
+              3. If it's a real issue, consider creating a hotfix
+              4. Update tests if the failure is due to intended changes
+              
+              ### Test Results
+              Check the uploaded artifacts for detailed test results and coverage information.
