In April 2025, Poelzi developed a new feature for the MystenLabs/walrus repository, focusing on enhancing the Walrus CLI by adding shell completion script generation. Using Rust and the clap_complete crate, Poelzi implemented a dedicated command that outputs completion scripts for Bash, Zsh, and Fish, streamlining the onboarding process and daily workflow for CLI users. The work involved integrating the completion generation seamlessly into the existing CLI flow, ensuring that developers could easily access and install completions. This contribution demonstrated practical CLI development and shell scripting skills, delivering a targeted improvement to developer experience within a single, well-scoped commit.
