Worked on the GitGuardian/ggshield repository, focusing on improving both the reliability of CLI features and the clarity of user documentation. Addressed a bug in the Incident Details CLI by refining the default handling of the --with-incident-details option, ensuring consistent display of incident information across all subcommands and reducing user confusion. Additionally, delivered a targeted documentation update clarifying the expected input format for the hmsl check command, which improved onboarding and reduced support overhead. Utilized Python for CLI development and bug fixing, and maintained documentation using Markdown, demonstrating attention to both technical stability and user experience within the project.
