vintner completion bash|zsh prints a completion script meant to be sourced (source <(vintner completion bash)); completes subcommands (including short aliases), download's flags, and directory arguments for install/env --bin. Mentioned in the top-level usage text and documented in the README. The Nivora package doesn't auto-install these system-wide yet - it'd need Stapler's install-completion helper, whose calling convention isn't documented anywhere in this repo or Nivora's other packages, so guessing at it risked a broken package build for a nice-to-have. source <(vintner completion bash) works today regardless of install method (Nivora, prebuilt binary, or from source).
