研究方向

Investigate the suggested library (omelette) or similar tools for generating shell completions. Look at how other CLI tools in the Dart ecosystem implement completions (e.g., Dart's own CLI completions). Review the sass command line interface to list all flags and arguments. Determine which shells to target (bash, zsh, fish). The issue has no maintainer response yet, so confirm with maintainers the desired scope before implementing.
