During August 2025, Khun Sang enhanced the pycbc_plot_singles_vs_params workflow in the gwastro/pycbc repository by improving the help and usability of the --filter-string command-line option. Using Python and a documentation-driven approach, Khun expanded the help string to include a clear usage example and clarified that filter parameters should originate from trigger or bank parameters. This targeted feature addressed user confusion, reduced support inquiries, and streamlined analyst onboarding for plotting workflows. The work demonstrated careful attention to user-facing documentation and command-line interface design, resulting in a maintainable enhancement that aligned with project standards and improved the overall user experience.
