The SQL Research skill provides a structured framework for investigating database-specific SQL functions, commands, and behaviors. It is designed to ensure technical accuracy by mandating a research-first workflow that prioritizes official documentation, tracks version-specific differences, and documents critical edge cases such as NULL handling and type coercion. By generating standardized research files, this skill helps developers build robust SQL translations, particularly for tools like dbplyr, while maintaining a clear audit trail of sources and limitations.
