            Hey @${{ github.event.issue.user.login }},
            
            your module submission is invalid. A valid submission title must match the pattern `^\[[mM]odule\][[:space:]]*([a-zA-Z][a-zA-Z0-9._-]+)$` (e.g., `[Module] my-module`), otherwise your module can't added.
            Please update your submission title and try again.
            
            *Best regards,  
            The MMAR Team*
