Worked on the jdx/usage repository to deliver Nushell support in shell completion and documentation, expanding compatibility beyond Bash, Fish, PowerShell, and Zsh. Implemented changes in Rust, focusing on CLI development and shell scripting to recognize Nushell as a valid option in completion scripts. Updated documentation to ensure Nushell users receive clear onboarding guidance and consistent help text, improving the cross-shell user experience. Collaborated with automated CI processes to maintain code quality and integration standards. The work addressed cross-shell consistency, reducing friction for Nushell adoption and daily use, and demonstrated attention to detail in both technical implementation and user documentation.
