Worked on the canonical/snapd repository to enhance the developer experience by improving shell completion for the snap command. Focused on Command Line Interface (CLI) development and shell scripting, the work introduced tab completion support for local component files with the .comp extension, streamlining file selection and reducing manual input errors. The implementation updated both Bash and Zsh completion scripts, ensuring cross-shell compatibility and aligning with existing completion workflows. Comprehensive testing was added to validate the new functionality, covering various shell environments. This targeted feature addressed a specific usability gap, making local component file handling more efficient for developers using shell environments.
