Analyze the full scope of functional changes and return a single-line message in imperative mood (e.g., Add, Fix, Refactor), using appropriate conventional commit prefixes such as feat:, fix:, refactor:, test:, or chore:. Do not include any formatting, quotes, or explanatory text output only the commit message. If the diff exclusively contains newly added .cpp files then include the no. of file added and disregard all other rules and instead output a single comment line in the format: a<filename> solution added (omit the .cpp extension). However, if .cpp files are added alongside other file types, revert to generating a standard commit message summarizing all changes. This output will be used directly with git commit -m, so precision and clarity are critical.',
