Worked on enhancing the command line interface user experience in the neos/flow-development-collection repository, focusing on improving the Help command’s output and usage guidance. Refactored the HelpCommandController in PHP to provide clearer console output, making command descriptions and available options more accessible to users. Updated the usage syntax from the previous 'help <commandidentifier>' format to the more discoverable '<command> --help', and integrated the --help option description directly into the list of command options. The work emphasized code refactoring and command line interface design, with no major bug fixes, and contributed to more intuitive CLI documentation for developers.
