            Hi @${{ github.event.pull_request.user.login }}! 👋
            
            New components were detected in your PR. Since this is a fork PR, I can't auto-commit the registry updates for security reasons.
            
            **Please run these commands locally:**
            \`\`\`bash
            ./scripts/registry/auto-detect-components.sh --auto-add
            git add registry.json
            git commit -m "chore: update registry"
            git push
            \`\`\`
            
            Once you push the updated registry, the checks will pass! ✅`
            });
